The social goals and social problem-solving of children who varied in social adjustment were examined in the context of hypothetical ambiguous provocation situations in which provocateurs' emotion displays were systematically manipulated. Children rated the importance of six different social goals and explained how they would solve the problems. Social adjustment was measured with rating and nomination sociometric procedures. Rejected-aggressive, rejected-nonaggressive, average-nonaggressive, and popular-nonaggressive children showed both commonalities and differences in rating the six social goals, the relative importance of the six social goals, and social problem-solving depending on the provocateur's emotion display. When provocateurs were happy, there were few group differences, but when provocateurs were angry or sad, rejected-aggressive children: a) rated hostile/instrumental goals more positively; b) rated prosocial goals less positively; and c) made problem-solving responses that were less friendly than those of other children. Results are discussed in relation to Lemerise and Arsenio's (2000) model of emotion and social information processing.

Object parts are signaled by concave discontinuities in shape contours. In seven experiments, we examined whether 5- and 6 1/2-month-olds are sensitive to concavities as special aspects of contours. Infants of both ages detected discrepant concave elements amid convex distractors but failed to discriminate convex elements among concave distractors. This discrimination asymmetry is analogous to the finding that concave targets among convex distractors pop out for adults, whereas convex targets among concave distractors do not. Thus, during infancy, as during adulthood, concavities appear to be salient regions of shape contours. The current study also found that infants' detection of concavity is impaired if the contours that define concavity and convexity are not part of closed shapes. Thus, for infants, as for adults, concavities and convexities are defined more readily in the contours of closed shapes. Taken together, the results suggest that some basic aspects of part perception from shape contours are available by at least 5 months of age.

This article demonstrates how taking the time out to play, commenting pungently on play, serving up surprise and adventure, and developing mutually understood codes or inside jokes help the psychiatrist to turn a child around. In this article, the authors categorized what principles of treatment their 10 vignettes about playfulness illustrated, they fell into four categories: (1) using the process of play to communicate; (2) commenting pungently and with good timing on play; (3) serving up creative surprise and adventure; and (4) developing mutually understood, imaginative "codes." Here, each author presents cases of each category.

This study investigated the influence of question repetition and question type (answerable, unanswerable, or opinion seeking) on children's recall. A total of 136 children (5-, 7-, and 9-year-olds) watched a live 15-min presentation. One week later, the children were asked 20 questions that were repeated an additional two times within the interview. Accuracy of children's responses to unanswerable questions declined with repetition. Children were more likely to change a response to an unanswerable question than to an answerable question. Overall, children maintained the same answers to only three-quarters of the repeated questions. The most common pattern of change was for children to change their answer the second time a question was asked and then to maintain that answer when questioned again. The high percentage of changed answers within a single interview has important implications for forensic interviewing.

Participants (6- and 7-year-olds, "N" = 130) participated in classroom activities four times. Children were interviewed about the final occurrence (target event) either 1 week or 4 weeks later, during which half of the event items were described inaccurately. Half of these suggestions were consistent with the theme of the detail across the occurrences (e.g., always sat on a kind of floor mat) or were inconsistent (e.g., sat on a chair). When memory for the target event was tested 1 day later, children falsely recognized fewer inconsistent suggestions than consistent suggestions, especially compared with a control group of children who experienced the event just one time. Furthermore, the longer delay reduced accuracy only for consistent suggestions. Source-monitoring ability was strongly and positively related to resistance to suggestions, and encouraging children to identify the source of false suggestions allowed them to retract a significant proportion of their reports of inconsistent suggestions but not of consistent suggestions. The results suggest that the gist consistency of suggestions determines whether event repetition increases or decreases suggestibility.

In this study, we investigated the development of basic effects that have been found in single-digit multiplication arithmetic: the problem size, five, and tie effects. Participants (9-,10-, and 11-year-olds and adults) performed a production task on simple multiplication. The procedure replicated Campbell and Graham's (1985) study ["Canadian Journal of Psychology," Vol. 39, pp. 338-366], but the results show that the gradual decrease of the problem size effect ends in sixth grade. We report analyses on raw latencies and state trace analyses that take into account reaction time scaling as a function of age. The results show that 11-year-olds do not differ significantly from adults on any of the three effects. Before 11 years of age, interesting developmental changes occur.

This study investigated associations between working memory (measured by complex memory tasks) and both reading and mathematics abilities, as well as the possible mediating factors of fluid intelligence, verbal abilities, short-term memory (STM), and phonological awareness, in a sample of 46 6- to 11-year-olds with reading disabilities. As a whole, the sample was characterized by deficits in complex memory and visuospatial STM and by low IQ scores; language, phonological STM, and phonological awareness abilities fell in the low average range. Severity of reading difficulties within the sample was significantly associated with complex memory, language, and phonological awareness abilities, whereas poor mathematics abilities were linked with complex memory, phonological STM, and phonological awareness scores. These findings suggest that working memory skills indexed by complex memory tasks represent an important constraint on the acquisition of skill and knowledge in reading and mathematics. Possible mechanisms for the contribution of working memory to learning, and the implications for educational practice, are considered.

Parents are increasingly expected to supplement their children's school-based learning by providing support for children's homework. However, parents' capacities to provide such support may vary and may be limited by the experience of depression. This may have implications for child development. In the course of a prospective, longitudinal study of children of postnatally depressed and healthy mothers, we observed mothers (N=88) and fathers (N=78) at home during maths homework interactions with their 8-year-old children. The quality of parental communication was rated and analysed in relation to child functioning. The quality of communication of each of the parents was related to their mental state, social class and IQ. While postnatal depression was not directly related to child development, there was some evidence of the influence of maternal depression occurring in the child's school years. Different aspects of parental communication with the child showed specific associations with different child outcomes, over and above the influence of family characteristics. In particular, child school attainment and IQ were associated with parental strategies to encourage representational thinking and mastery motivation, whereas child behavioural adjustment at school and self-esteem were linked to the degree of parental emotional support and low levels of coercion. Notably, the influence of maternal homework support was more strongly related to child outcome than was paternal support, a pattern reflected in mothers' greater involvement in children's schools and school-related activities. Some parents may need guidance in how to support their children's homework if it is to be of benefit to child functioning.

State and trait anxiety define different aspects of anxiety, and may represent environmentally and genetically mediated components of this phenotype. Furthermore their relationship, where trait anxiety is expressed through levels of state anxiety under threatening circumstances, may represent a process of interplay between a genetic vulnerability factor and an environmental stressor. To test these hypotheses, we explored genetic and environmental influences on measures of state and trait anxiety in a sample of 1058 twins (521 males and 537 females) aged 8-16. The results were consistent with these hypotheses. State anxiety is largely influenced by environmental factors in males and females whereas trait anxiety shows moderate genetic effects and substantial non-shared environment effects. Their association was accounted for by non-shared environmental effects, with modest genetic and shared environmental inputs. The implications of these results for vulnerability mechanisms involving stress reactivity on anxiety are discussed.

This paper is a commentary of the special series on involving fathers in psychological services for children. The following themes are addressed: the effects of fathers on child development; benefits of father involvement in child psychology services; obstacles to father involvement; engaging fathers; specific interventions for fathers; and implications for service development, training, and research.

Very young infants are sensitive to and follow other people's gaze. By 18 months children, like chimpanzees, apparently represent the spatial relationship between viewer and object viewed: they can follow eye-direction alone, and react appropriately if the other's gaze is blocked by occluding barriers. This paper assesses when children represent this relationship as psychological in nature. Studies examining sensitivity to gaze, gaze following, and explicit judgement of gaze direction are reviewed. The evidence suggests that neither infants nor chimpanzees represent gaze as psychological. It is concluded that mentalistic gaze understanding develops from the age of 3 years.

This article highlights the defining principles, progress and future directions in developmental psychopathology in relation to this special section. Six fundamental principles of developmental psychopathology are identified and the pervasive impact of this integrative framework on research, theory, and practice in behavioral health fields over the past three decades is described. This special section reflects the increasing influence of developmental systems theory, the growing focus on "change", intensifying interest in translational research, and the increasingly complex and differentiated nature of research on pathways toward and away from psychopathology. A new era in developmental psychopathology is dawning, with exciting frontiers in brain development and plasticity, gene-environment interaction, resilience and recovery, multilevel dynamics, interdisciplinary research and training, and methodologies for assessing and analyzing change over time within and across individual systems and their contexts. (Contains 2 tables.)

The vision for "School Psychology Review" for the 2006-2010 editorial term is described, and five major goals are outlined. These goals include (a) addressing issues of critical importance to school psychology and the broader domains of child-oriented psychology and education; (b) promoting intervention and prevention research and publishing this work in its various stages of development; (c) strengthening the link between science and practice; (d) promoting a cross-fertilization of ideas through interdisciplinary collaboration; and (e) building the infrastructure through the use of electronic technologies. Strategies that will be used by the leadership team of "SPR" to address each goal during the next 5 years are described. (Contains 1 figure, 1 table and 1 footnote.)

Resilience allows one to achieve emotional health and social competence in spite of a history of adversity. There are three waves of resilience research. The first wave, 40 years ago, examined risk factors in children. The second wave of research asked the question, what do resilient children look like? These studies concluded that while there is not a universal set of traits among resilient children, children who beat the odds usually demonstrate a cluster of characteristics. The second wave also examined conditions that buffer children from the negative effects of risk factors. An important finding from the second generation of resilience research is that resilience is not innate. People acquire resilience. It's a learned behavior. This finding has obvious implications for parents and educators. It means there are things they can do to promote resilience in children. This is the focus of the third wave of research. In this article, the author describes what people can do to enhance a child's ability to achieve emotional health, social competence, and academic success in the face of adversity.

A core task in language acquisition is mapping words onto objects, actions, and events. Two studies investigated how children learn to map novel labels onto novel objects. Study 1 investigated whether 10-month-olds use both perceptual and social cues to learn a word. Study 2, a control study, tested whether infants paired the label with a particular spatial location rather than to an object. Results show that 10-month-olds can learn new labels and do so by relying on the perceptual salience of an object instead of social cues provided by a speaker. This is in direct contrast to the way in which older children (12-18 and 24-month-olds) learn and extend new object names.

Four-year-olds were tested for their ability to use differences in the spacing among features to recognize familiar faces. They were given a storybook depicting multiple views of 2 children. They returned to the laboratory 2 weeks later and used a "magic wand" to play a computer game that tested their ability to recognize the familiarized faces and their own face based on the spacing of features. Children performed at chance levels. Follow-up studies confirmed that they had attended to internal facial features and validated the stimuli. The results contrast with studies showing some sensitivity to the spacing of features in infants and preschool children; multiple mechanisms of face processing may make use of spatial relations and develop at different rates.

Three studies (N=144) investigated how toddlers aged 18 and 24 months pass the surprise-mark test of self-recognition. In Study 1, toddlers were surreptitiously marked in successive conditions on their legs and faces with stickers visible only in a mirror. Rates of sticker touching did not differ significantly between conditions. In Study 2, toddlers failed to touch a sticker on their legs that had been disguised before being marked. In Study 3, having been given 30-s exposure to their disguised legs before testing, toddlers touched the stickers on their legs and faces at equivalent levels. These results suggest that toddlers pass the mark test based on expectations about what they look like, expectations that are not restricted to the face.

Background: The relationship between the age of reaching infant developmental milestones and later intellectual function within the normal population remains unresolved. We hypothesised that the age of learning to stand in infancy would be associated with adult executive function and that the association would be apparent throughout the range of abilities, rather than confined to extremes. Methods: The Northern Finland 1966 Birth Cohort is based upon 12,058 live-born children in a geographic and temporally defined population. Information on age at learning to stand without support was obtained at one year. At age 33-35 a random sample of 104 subjects underwent a neuropsychological test battery including tests of executive function (cognitive categorisation), visuo-spatial memory, verbal learning and visual object learning. We investigated associations between developmental data and adult neuropsychological test scores. Results: There was a significant linear relationship between age of learning to stand and adult categorisation: the earlier the attainment of the milestone, the better was the categorisation. No such relationships were observed between infant neurodevelopment and adult cognition in other neuropsychological domains. Conclusion: Even within the normal range of development, early development in the gross motor domain is associated with better adult executive function (in tests of categorisation). Investigation of the determinants and sequelae of normal neural development will facilitate research into a variety of neurodevelopmental disorders.

This article reports on the findings of a questionnaire survey of 142 educational psychologists from England and Wales on their approach to the assessment of children with learning and behavioural problems. Participants were asked to report on the frequency with which they used a variety of approaches to assessment, including interviews with pupils and parents, observations, psychometric tests of ability and achievement, criterion referenced approaches and dynamic assessment. They were also asked to indicate the approaches that they found most useful. The findings indicate that partial psychometric assessments of ability feature prominently in the assessment of children with learning difficulties, though less in the assessment of children with behaviour problems. Approaches based on dynamic assessment are not used frequently although those who do use them find them to be useful to the purpose of the assessment. On the whole, the educational psychologists in this survey were not influenced by the written guidance proposed by the professional associations--the Division of Educational and Child Psychology and the Association of Educational Psychologists. In addition, 40 percent of respondents indicated that their work was not influenced by any one or more theoretical orientations in psychology that could be linked to the origins of behaviour or learning difficulties or about approaches to intervention. The findings are discussed in the light of developments in which the British Government is proposing to introduce wholesale changes to the ways in which services for children will be organized and to the professional roles and qualifications of different helping professions. Within these developments, it seems likely that educational psychologists will be required to justify their distinctive contribution to child assessment and intervention.

Findings yielded a comprehensive portrait of the predictive relations among children's aggressive or withdrawn behaviors, peer rejection, and psychological maladjustment across the 5-12 age period. Examination of peer rejection in different variable contexts and across repeated intervals throughout childhood revealed differences in the timing, strength, and consistency of this risk factor as a distinct (additive) predictor of externalizing versus internalizing problems. In conjunction with aggressive behavior, peer rejection proved to be a stronger additive predictor of externalizing problems during early rather than later childhood. Relative to withdrawn behavior, rejection's efficacy as a distinct predictor of internalizing problems was significant early in childhood and increased progressively thereafter. These additive path models fit the data better than did disorder-driven or transactional models.

A major form of data analysis in clinical child and adolescent psychology is multiple regression. This article reviews issues in the application of such methods in light of the research designs typical of this field. Issues addressed include controlling covariates, evaluation of predictor relevance, comparing predictors, analysis of moderation, analysis of mediation, assumption violations, outliers, limited dependent variables, and directed regression and its relation to structural equation modeling. Analytic guidelines are provided within each domain.

The emotional trauma of recent events may never go away. A million people were uprooted by Hurricane Katrina, including an estimated 372,000 children of school age. Three weeks later, Hurricane Rita slammed into the Texas-Louisiana coastline, forcing thousands more to evacuate. Acute symptoms of trauma range from confusion, nightmares, and clinging behavior in young children to sleep disturbances, depression, and fighting in preadolescents and teens. Months or perhaps years later, some may also develop Post Traumatic Stress Syndrome, which typically occurs with crime victims and soldiers in combat and is characterized by disturbing flashbacks and panic attacks. Academic problems could be exacerbated by the high level of poverty among evacuees. The combined effect of poverty-related problems and trauma from the storms could be debilitating for some children, experts say. The good news is that children can be remarkably resilient, often more so than their parents, said Howard Adelman, co-director of the Center for Mental Health in Schools at UCLA. After the hurricanes, parents must deal with the added stressors of insurance, housing, and employment. Kids just need to look after themselves. Schools can help them build resiliency by linking them with adult mentors and student buddies, experts say. School boards can cut red tape that may prevent students from getting needed help, especially important for those who had academic or emotional problems before the storms. Teachers should be careful not to pour on needless academic work, yet at the same time not treat evacuees differently because of what they went through. Developing new routines, new challenges--in short, a new sense of normalcy--is key to helping these children recover.

Urie Bronfenbrenner (1917-2005) was a pioneer in studying the behavior of children in their natural life space of family, school, peer group, and community. His concept of the ecology of human development is transforming practice for effective work with children and youth. Bronfenbrenner's research highlights the power of human relationships to propel children on pathways to problematic or positive life outcomes. (Contains 3 notes.)

Three-month-olds are sensitive to orientation changes of line drawings when they have a three-dimensional (3-D) interpretation and when the changes are defined by both 3-D depth and two-dimensional (2-D) picture plane cues [Bhatt, R. S., & Bertin, E. (2001). Pictorial cues and three-dimensional information processing in early infancy. Journal of Experimental Child Psychology, 80, 315-332]. In the current study, we examined whether 3-month-olds are sensitive to pictorial line junction cues that signal orientation changes solely in the 3-D depth plane. The results revealed that infants discriminated a misoriented elongated cube in an array when the stimuli contained both shading and lines (Experiment 2) but not when only lines depicted the elongated cubes (Experiment 1). Testing with comparable 2-D images revealed that, even in the presence of shading information, detection of orientation changes is specific to images that have a 3-D interpretation. Together, the results suggest that 3-month-olds are sensitive to pictorial line junction cues that signal orientation changes in the 3-D depth plane to adults provided that shading information is available and the images have a 3-D interpretation.

Adults' source judgments are more accurate when they focus on speakers' emotions than when adults focus on their own emotions. Focusing on speakers may lead to better source memory because it encourages processing of the perceptual characteristics of the source and binding of that information to the content of what is being said. The purpose of the current work was to evaluate whether young children's source memory similarly benefits from this outward encoding focus and whether this effect changes developmentally. In Experiment 1, when 4- and 5-year-olds heard an audiotape of two dissimilar speakers, only the 5-year-olds showed better source memory when asked to adopt an other-focus. In Experiment 2, when 4- and 5-year-olds watched a videotape of two similar speakers, the same pattern was found. However, in Experiment 3, when 4-year-olds watched a videotape of two dissimilar speakers (a more optimal encoding condition in which 5-year-olds showed ceiling performance), 4-year-olds benefited from taking an other-focus during encoding. Overall, the data suggest that the benefit for source memory of focusing on another person develops over the preschool years.

Objective: To devise and test a model describing the process of help-seeking for child psychopathology in professional and informal service settings. Method: Using structural equation modeling, associations between several help-seeking stages, and the influence of child, family, and context characteristics on these stages were investigated in 246 Dutch children (4-11 years old) between April 2000 and July 2002. Children were selected for having emotional or behavioral problems from a representative general practice sample; 68% of the selected children participated. Results: School personnel played an important role in the process of help-seeking for child psychopathology, in both detecting service need and the provision of and the referral for help. Although Dutch general practitioners are supposed to be gatekeepers of mental health care, their role in help-seeking for child psychopathology was limited. Various family characteristics were shown to influence service need and informal or professional help-seeking. The influence of child characteristics on the help-seeking process was limited. Conclusions: Educating parents about child psychopathology and the availability and accessibility of care, improving general practitioners' skills in detecting child psychopathology, and direct contact of mental health professionals with general practitioners and schools may enhance access to care for children in need.

Objective: We investigated the role of genetic and environmental factors in the developmental association among symptoms of eating disorders, depression, and anxiety syndromes in 8-13-year-old and 14-17-year-old twin girls. Methods: Multivariate genetic models were fitted to child-reported longitudinal symptom data gathered from clinical interview on 408 MZ and 198 DZ female twin pairs from the Virginia Twin Study of Adolescent Behavioural Development (VTSABD). Results: Model-fitting revealed distinct etiological patterns underlying the association among symptoms of eating disorders, depression, overanxious disorder (OAD), and separation anxiety disorder (SAD) during the course of development: 1) a common genetic factor influencing liability to all symptoms--of early and later OAD, depression, SAD, and eating symptoms; 2) a distinct genetic factor specifically indexing liability to early eating disorders symptoms; 3) a shared environmental factor specifically influencing early depression and early eating disorders symptoms; and 4) a common environmental factor affecting liability to symptoms of later eating disorders and both early and later separation anxiety. Conclusions: These results suggest a pervasive genetic effect that influences liability to symptoms of over-anxiety, separation anxiety, depression, and eating disorder throughout development, a shared environmental influence on later adolescent eating problems and persistent separation anxiety, genetic influences specific to early eating disorders symptoms, and a shared environmental factor influencing symptoms of early eating and depression.

This study investigated children's sensitivity to spelling consistency, and lexical and sublexical (rime) frequency, and their use of explicitly learned canonical vowel graphemes in the early stages of learning to spell. Vowel spellings produced by 78 British children at the end of reception year (mean age 5 years, 7 months) and 6 months later in mid-Year 1 were assessed. Regression analyses revealed that, at both test times, knowledge of sound-letter correspondences influenced spelling performance; however, unconditional consistency of vowel spellings affected children's spelling most strongly, over and above additional effects of word and rime frequency and the complexity of the target vowel grapheme. The effect of conditional consistency of vowel spellings given coda contexts was not significant. Thus, young children are sensitive to various statistical properties of the orthography from the earliest phases of spelling development and, in particular, to the unconditional consistency of the vowel spelling pattern.

Geudens and Sandra, in their 2003 study, investigated the special role of onsets and rimes in Dutch-speaking children's explicit phonological awareness. In the current study, we tapped implicit phonological knowledge using forced-choice similarity judgment (Experiment 1) and recall of syllable lists (Experiment 2). In Experiment 1, Dutch-speaking prereaders judged rime-sharing pseudowords (/f[alpha]s/-/m[alpha]s/) to sound more similar than pseudowords sharing an equally sized nonrime unit (/f[alpha]s/-/f[alpha]k/). However, in a syllable recall task (/t[epsilon]f/, /r[iota]s/, /n[alpha]l/), Dutch-speaking prereaders were as likely to produce recombination errors that broke up the rime (/t[epsilon]s/) as to produce errors that retained the rime (/r[epsilon]f/). Thus, a rime effect was obtained in a task that highlighted the phonological similarity between items sharing their rimes, but this effect disappeared in tasks without repetition of rime units. We conclude that children's sensitivity to rimes depends on similarity relations and might not reflect a fixed perceived structure of spoken syllables.

In Dutch, vowel duration spelling is phonologically consistent but morphologically inconsistent (e.g., "paar--paren"). In German, it is phonologically inconsistent but morphologically consistent (e.g., "Paar--Paare"). Contrasting the two orthographies allowed us to examine the role of phonological and morphological consistency in the acquisition of the same orthographic feature. Dutch and German children in Grades 2 to 4 spelled singular and plural word forms and in a second task identified the correct spelling of singular and plural forms of the same nonword. Dutch children were better in word spelling, but German children outperformed the Dutch children in nonword selection. Also, whereas German children performed on a similar level for singular and plural items, Dutch children showed a large discrepancy. The results indicate that children use phonological and morphological rules from an early age but that the developmental balance between the two sources of information is constrained by the specific orthography.

Background: Whether selective attention is a primary deficit in childhood Attention Deficit Hyperactivity Disorder (ADHD) remains in active debate. Methods: We used the "perceptual load" paradigm to examine both early and late selective attention in children with the Primarily Inattentive (ADHD-I) and Combined subtypes (ADHD-C) of ADHD. Results: No evidence emerged for selective attention deficits in either of the subtypes, but sluggish cognitive tempo was associated with abnormal early selection. Conclusions: At least some, and possibly most, children with DSM-IV ADHD have normal selective attention. Results support the move away from theories of attention dysfunction as primary in ADHD-C. In ADHD-I, this was one of the first formal tests of posterior attention network dysfunction, and results did not support that theory. However, ADHD children with sluggish cognitive tempo (SCT) warrant more study for possible early selective attention deficits.

Background: Studies of school-aged children, adolescents, and adults with Attention Deficit/Hyperactivity Disorder (ADHD) have variably shown ADHD-related impairment in both inhibitory control and sustained attention. However, few studies have examined ADHD-associated patterns of performance on these tasks among younger children (below age 7 years). Methods: A combined continuous performance test and go/no-go task (CPT/GNG) and the Day-Night Stroop Task (DNST) were administered to an ethnically diverse sample of 3.44- to 6.95-year-old children rated by parents and teachers as being either high risk or low risk for ADHD. All children performed the DNST (N = 71) and a subset of the sample (N = 44) performed the CPT/GNG. Analyses assessed task validity as well as the effects of age and risk status. Results: Significant main effects for age and risk status were found on all tasks. In addition, age x condition interactions were found for the CPT and DNST, which suggest that the tasks were sensitive to age-related changes in sustained attention and inhibitory control respectively. No significant risk status x condition interactions were found, suggesting that young children at risk for ADHD do not exhibit specific deficits in either inhibitory control or sustained attention. The most consistent effect related to risk status across tasks was the greater number of errors and longer and more variable reaction times on the part of children at risk for ADHD irrespective of condition. Conclusions: ADHD-associated decrements in performance on these tasks appear to be attributable either to generalized behavioral dysregulation or poor state regulation rather than to deficient inhibitory control.

This study explored different gradations of emulation in the imitation of actions on objects by 17-month-olds. Experiment 1 established levels of behavioral reproduction following prerecorded video demonstrations similar to those levels following live demonstrations. In Experiment 2, two digitally modified videos, where object movements or body movements critical to producing the target action were highlighted in isolation, were developed. Infants produced the target action equally frequently by observing the object movement video and observing the unmodified video. In contrast, their performance was much less successful based on the body movement video. In Experiment 3, the performance obtained following the object movement video was similar to that following a further video that emphasized the object movements produced in unsuccessful attempts to produce the target action. These findings suggest that emulation in the form of object movement reenactment or affordance learning plays a role in the social learning of actions on objects during infancy.

Romanian adoptees have a background of severe neglect. International research has shown that this can give rise to symptoms of autistic behavior. Rutter "et al." (1999, "Journal of Child Psychology Psychiatry," 40 (4), 537-549.) refers to "quasi-autistic patterns", and Federici (1998, "Help for the hopeless child: A guide for families." Alexandria: Federici & Assocoates.) to Post-Institutional Autistic Syndrome (PIAS). Eighty Romanian adoptees, averaging 8 years of age, who had resided in the Netherlands for 5 years were studied. Parent interviews and the Auti-R scale showed the extent to which the children exhibited PIAS. In one third of these children we observed (in addition to other behavioral problems) stereotypic behaviors and communication and language disorders. Our findings resembled the Rutter "et al." (1999, "Journal of Child Psychology Psychiatry," 40 (4), 537-549.) data. Six of the children were classified within the autistic spectrum pursuant to the Auti-R, and seven within the so-called intermediate group. No difference was found between the girls and the boys. Children who had been in their adoptive families for 5 years or more showed fewer behavior problems than children who had been in their adoptive families for four or less years.

Systemic analyses of psychological functioning in families of children with autism have typically shown that parents report different experiences (e.g., stress) and that siblings may also be affected. The purpose of the present research was more explicitly to address relationships between child, partner, and parent variables. Parents of 48 children with autism (41 mother-father pairs) reported on child characteristics, and their own stress and mental health. Mothers were found to report both more depression and more positive perceptions than fathers. Regression analyses revealed that paternal stress and positive perceptions were predicted by maternal depression; maternal stress was predicted by their children's behavior problems (not adaptive behavior or autism symptoms) and by their partner's depression. The future testing of the mechanisms underlying these results is discussed. In addition, the need is emphasized for more systemic analyses to understand the psychological functioning of children with autism and their siblings and parents.

Background: There is a growing interest in the study of the genetic origins of comorbidity, a direct consequence of the recent findings of genetic loci that are seemingly linked to more than one disorder. There are several potential causes for these shared regions of linkage, but one possibility is that these loci may harbor genes with manifold effects. The established genetic correlation between reading disability (RD) and attention-deficit/hyperactivity disorder (ADHD) suggests that their comorbidity is due at least in part to genes that have an impact on several phenotypes, a phenomenon known as pleiotropy. Methods: We employ a bivariate linkage test for selected samples that could help identify these pleiotropic loci. This linkage method was employed to carry out the first bivariate genome-wide analysis for RD and ADHD, in a selected sample of 182 sibling pairs. Results: We found evidence for a novel locus at chromosome 14q32 (multipoint LOD = 2.5; singlepoint LOD = 3.9) with a pleiotropic effect on RD and ADHD. Another locus at 13q32, which had been implicated in previous univariate scans of RD and ADHD, seems to have a pleiotropic effect on both disorders. 20q11 is also suggested as a pleiotropic locus. Other loci previously implicated in RD or ADHD did not exhibit bivariate linkage. Conclusions: Some loci are suggested as having pleiotropic effects on RD and ADHD, while others might have unique effects. These results highlight the utility of this bivariate linkage method to study pleiotropy.

Background: The seven papers in this special section chart where we are in the quest for quantitative trait loci (QTLs) in key areas of child psychology and psychiatry such as reading and hyperactivity. But we are not there yet. Methods: This commentary considers some new developments that are likely to accelerate the journey towards the identification of QTLs. Results: The single most important factor is the need for very large samples to attain adequate power to detect and replicate QTLs of very small effect size. Another important development is the microarray, which makes it possible to genotype hundreds of thousands of SNPs simultaneously. Using microarrays in association studies allows SNPs across the whole genome to be genotyped. Microarrays will boost power even more when they contain all functional polymorphisms in the genome, including functional non-coding DNA. Conclusions: Once replicable QTLs are identified in areas such as reading and hyperactivity, the real journey will begin. Future studies will use sets of QTLs as genetic risk indicators in top-down behavioural genomic research, leading to gene-based diagnoses, gene-based treatments tailored to the individual, and early warning systems and interventions. These discoveries will eventually help to prevent or at least ameliorate childhood disorders before they cast their long shadow over development.

The association between the development of antisocial behavior, affiliation with deviant friends, and peer rejection was tested with a preventive intervention; 664 boys and girls were randomly assigned to a universal classroom-based intervention targeting disruptive behavior or a control condition. Peer nominations of antisocial behavior, friends' antisocial behavior, and peer rejection were assessed annually for 4 years. A high, a moderate, and a stable low antisocial behavior trajectory were identified. Large reductions in antisocial behavior were found among intervention children who followed the high trajectory. These reductions coincided with affiliations with nondeviant peers and with decreases in peer rejection. The affiliation between deviant and nondeviant peers was initiated by nondeviant children. The results support a causal role of deviant friends and peer rejection in the development of antisocial behavior. The implications for our understanding of the mechanisms leading to reductions in antisocial behavior are discussed.

In response to the serious crisis in mental health care for children in the United States, this article proposes as a priority for psychology a comprehensive approach that treats mental health as a primary issue in child health and welfare. Consistent with the principles of a system of care and applying epidemiological, risk-development, and intervention-research findings, this approach emphasizes 4 components: easy access to effective professional clinical services for children exhibiting disorders; further development and application of sound prevention principles for high-risk youths; support for and access to short-term intervention in primary care settings; and greater recognition and promotion of mental health issues in common developmental settings and other influential systems. Integral to this approach is the need to implement these components simultaneously and to incorporate family-focused, culturally competent, evidence-based, and developmentally appropriate services. This comprehensive, simultaneous, and integrated approach is needed to achieve real progress in children's mental health in this country.

This article is intended to serve as a practical guide for practitioners interested in incorporating evidence-based diagnosis (EBD) instruments into their clinical practices to refine the diagnostic process. Three measures are used to illustrate this process, the DISC-IV (Shaffer et al., 2000), the Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime version (K-SADS-PL) (Kaufman, et al., 1996), and the Achenbach System of Empirically Based Assessment (ASEBA) School-Age Forms (i.e., the Child Behavior Checklist, the Youth Self-Report Form, and the Teacher's Report Form; Achenbach and Rescorla, 2001). The purpose of this article is not to advocate for incorporation of these specific measures into clinical practice but rather to provide interested practitioners with useful information to make decisions about what form of EBD may be most appropriate for their own practice settings. Guidelines are provided for practitioners, including suggestions for identifying instruments, examining the evidence in support of those instruments, evaluating the feasibility of using those instruments in clinical practice, and implementing them.

In this study, the author examined the relationship between theory-of-mind understanding and preschool-aged children's peer-related social competence. One hundred eleven 3- to 5-year-old children (48 boys, 63 girls) participated in 2 theory-of-mind tasks designed to assess their understanding of false belief. Teachers rated children's peer-related social behavior in terms of prosocial behavior, aggressive or disruptive behavior, and shy or withdrawn behavior. Results indicated that, after controlling for age, theory-of-mind understanding significantly predicted aggressive or disruptive behavior for boys and prosocial behavior for girls. Theory-of-mind understanding also was related to lower scores of shy or withdrawn behavior for boys. Results are discussed in terms of the gender differences in the factors contributing to early peer competence. (Contains 6 tables and 1 figure.)

This study investigated gender differences in kindergarteners' literacy skills, specifically, whether differences in children's classroom behaviors explained females' early learning advantage. Data included information on 16,883 kindergartners (8,701 boys and 8,182 girls) from the Early Childhood Longitudinal Study, Kindergarten Cohort of 1998-1999 (ECLS-K). The ECLS-K directly assessed children's cognitive skills and collected extensive data on children's sociodemographic and behavioral backgrounds through structured telephone interviews with parents and written surveys with children's teachers. Findings suggested that not only did girls enter kindergarten with somewhat stronger literacy skills but they also learned slightly more than boys over the kindergarten year. Taking into account teachers' reports of girls' more positive learning approaches (e.g., attentiveness, task persistence) explained almost two-thirds of the female advantage in literacy learning. Accounting for boys' more prevalent external behavior problems, thought by many to explain girls' advantage in literacy development, did little to diminish the gender gap.

Objective: This study compared experiences of children sexually abused by peers to those of children abused by adolescents/adults. Variables examined included perceived negativity of the abuse, self-reported outcomes, overall psychological functioning, and disclosure. Method: An archival data set containing retrospective reports of childhood sexual experiences was culled for instances of sexual abuse by child peers and adolescents/adults. An equivalent nonabused comparison group was identified. The Self-Report Outcome Checklist (SROC; Gilbert, 1994b), the MMPI-Hugo Short Form (Hugo, 1971) and a disclosure survey were also retrieved from these data. Results: Compared to abuse by peers, abuse perpetrated by adolescents/adults was more intrusive and intrafamilial. Both groups rated their experiences as equally negative, and reported equally pervasive outcomes. Those abused by adolescents/adults reported significantly higher scores on the Psychopathic Deviate, Psychasthenia, and Schizophrenia scales compared to nonabused controls; similar findings did not emerge for those abused by child peers. Less than a fourth in either abuse group reported disclosing their experience to a parent. Among those who did not disclose, participants abused by child peers anticipated less support from both parents and more anger from their mothers. Conclusions: The findings suggest that child peer sexual abuse may be associated with adverse outcomes.

The concept and measurement of psychopathy in young people is discussed with respect to five key issues: (1) the respective merits of self-reports and ratings by others; (2) whether callous/unemotional (CU) features may be more appropriately tapped by physiological measures; (3) the possible utility of genetic studies; (4) the distinctiveness of CU from other risk factors for antisocial behavior; and (5) the homogeneity of CU as a construct.

The current study tests whether the presence of callous-unemotional (CU) traits designates a group of children with conduct problems who show an especially severe and chronic pattern of conduct problems and delinquency. Ninety-eight children who were selected from a large community screening of school children in grades 3, 4, 6 and 7 were followed across four yearly assessments. Children with conduct problems who also showed CU traits exhibited the highest rates of conduct problems, self-reported delinquency, and police contacts across the four years of the study. In fact, this group accounted for at least half of all of the police contacts reported in the sample across the last three waves of data collection. In contrast, children with conduct problems who did not show CU traits continued to show higher rates of conduct problems across the follow-up assessments compared to non-conduct problem children. However, they did not show higher rates of self-reported delinquency than non-conduct problem children. In fact, the second highest rate of self-reported delinquency in the sample was found for the group of children who were high on CU traits but without conduct problems at the start of the study.

The construct validity of psychopathy was examined in a sample of 114 male and female young offenders ([M.sub.age] = 15.16) at a southeastern detention center. The interpersonal circumplex served as a framework of general personality from which to examine the construct of adolescent psychopathy. A supplementary analysis of the psychopathy measures and the Big 5 factors of personality was also conducted using a matrix approach. Measures included: (a) Antisocial Process Screening Device (P. J. Frick & R. D. Hare, 2001); (b) Child Psychopathy Scale (D. R. Lynam, 1996); (c) Psychopathy Checklist--Youth Version (A. E. Forth, D. S. Kosson, & R. D. Hare, 2003); and (d) Interpersonal Adjective Scales Revised--Big 5 Version (P. Trapnell & J. S. Wiggins, 1991; J. S. Wiggins, 1995). Results showed substantial convergence among the three psychopathy measures. In addition, meaningful associations between psychopathy and constructs within the interpersonal circumplex and broader domains of the Big 5 were obtained. Two psychopathy scales correlated to a higher degree than expected with neuroticism. These findings provide evidence linking personality theory to the concept of child and adolescent psychopathy, thereby adding to its construct validity. However, they do so with the caveat that youth may also be displaying some characteristics of neuroticism, suggesting that worry and anxiety may accompany psychopathic features in earlier developmental stages. The implications of the current study are discussed. (Contains 7 notes.)

The cultural contexts of home, school and community all have important parts to play in the music education of children, but at present in Australia, these three entities are insufficiently connected on a number of fronts, not the least being an understanding about the purpose(s) of young people's engagement with music. This paper puts forward two specific proposals for action aimed to help build linkages among the three cultural contexts and ensure young people's on-going engagement with music. These proposals, which call on the education sector to assume leadership for action, have implications for policy makers, school personnel, as well as parents, individual artists and community arts organisations.
