It has been hypothesized that ADHD is associated both with difficulties in mathematical problem solving and in updating information in working memory. However, the relationship between updating and performance on mathematical word problems has never been studied for children with ADHD. The present study examined these issues comparing the performance of solving mathematical word problems (with no updating request vs high updating request) in a group of 11-12year old children with ADHD compared to a matched control group with typical development (TD). Results showed that children with ADHD solved fewer problems correctly than typically-developing children; moreover they made more errors in solving problems with updating requirements than those without updating requirements. In contrast, typically-developing children did not show any differences in problems performance on problems with and without updating requirements. Fine grained analyses of children's problem solving processes showed that children with ADHD found more difficult to select the appropriate data prior to calculation and to choose and execute the correct solution than typically-developing children. The difficulty to select the appropriate data results more severe in problems with updating requirements. Overall, these results support the hypothesis that the learning difficulties of children with ADHD are related to their executive dysfunctions, that negatively affect complex tasks requiring updating of to-be-processed information.

In recent years, teachers in Western countries have developed beliefs and attitudes related to working with students with specific learning disabilities (LD) that may be critical in shaping their educational practices with them; however, their beliefs and attitudes differ across political and geographical contexts and may be influenced by specific contextual circumstances and national legislation. This study examines these issues by comparing beliefs and attitudes among 557 primary school teachers from specific areas of three countries (Italy, Spain, and the United States). Results from this study support the hypothesis that, in general, teachers in these areas are sufficiently well informed about students with LD and are in favor of policies supporting these students’ needs. However, substantial differences emerge among countries about the etiology of LD; teachers’ and specialists’ roles in managing LD students; intervention planning, inclusion, and compensatory provisions; and the range of emotional attitudes that teachers exhibit. These differences have implications for intervention and suggest that efforts should be made to increase collaboration and promotion of common policies across countries.

Objective: The hypothesis behind this study was that trained teachers using cooperative learning procedures with children in their classroom (aged from 6 to 10 years) can influence the social skills of children with ADHD symptoms and their acceptance by their peers. Method: The study involved 30 children with ADHD symptoms attending 12 different classes, where cooperative learning was adopted in some, and standard practices in others. ADHD children’s symptoms, social skills, and cooperative behavior were assessed by means of a teacher’s questionnaire, and the social preferences of the children in their class were collected. Results: Changes emerged in teachers’ assessments of the children’s cooperative behavior in the experimental classes. Improvements in the sociometric status of children with ADHD symptoms were only seen in the cooperative learning classes. Conclusion: These results show the importance of well-structured intervention in classes that include children with ADHD symptoms. Implications of these findings for future intervention are discussed.

Research has shown that individuals with dyslexia have difficulty in reading not only in their native language but also in a second language (L2). The considered L2, however, has always been a language acquired through exposure to both written and oral forms. The present study examines the case of Italian adolescents reading in Latin as an L2, which is the special case of a dead language with very limited use of orality. As the learning of Latin is mainly based on the acquisition of grammar, this study also examined the relationship between grammatical proficiency and reading ability in Latin. Results suggested that, compared with control peers, students with dyslexia had difficulty in reading words and non-words in Latin. Interestingly, in spite of Latin being learnt mainly through written language, the extent of their difficulty was no larger than they encountered when reading in their native language. Also, despite the fact that students with dyslexia showed relatively less severe difficulties with Latin grammar (as compared to reading), this did not support them when reading Latin words, unlike typical readers. The theoretical and educational implications of these results are discussed.

La complessità del campo delle capacità matematiche rende particolarmente articolato e intricato lo studio delle disabilità d’apprendimento a esso associate.Teoricamente una disabilità nell’apprendimento matematico può derivare da un deficit nell’abilità di rappresentare o elaborare l’informazione da utilizzare in una o in tutte le varie aree della matematica (per esempio, comprensione numerica, calcolo e aritmetica elementare, ragionamento e soluzione dei problemi, algebra, geometria). Il capitolo tratta tali aspetti alla luce dei recenti modelli teorici analizzando in modo critico i risultati sperimentali nel campo del ragionamento matematico e nella soluzione dei problemi.

We used structural equation modeling to study individual age-related differences in working memory, processing speed, and the general ability of intelligence. The study took advantage of the Italian Wechsler Adult Intelligence Scale 4th edition (WAIS-IV) standardization sample (N = 2174) to obtain separate measures of working memory, processing speed, and general ability. Core and supplemental subtests were administered to 16–90 years old participants to ensure breadth of cognitive assessment and broad age coverage. Both linear and quadratic ages were associated with processing speed and working memory, which entirely accounted for the relationship between participants' age and general ability. Specific indirect relationships revealed that age-related differences in working memory weighed more than cognitive speed in predicting individual differences in general ability. Processing speed and working memory sharply decreased after 34 and 44 years of age, respectively. Like working memory, general ability decreased after 44 years of age. Bearing in mind the cognitive changes across adulthood and old age, our findings support the view that working memory is a more proximal source of age-related differences in intelligence than the cognitive processing speed.

A multigroup bifactor model was used to compare the explained variance and the reliability of the general vs. specific factors of the Wechsler Intelligence Scale for Children-4th edition (WISC-IV) in 1617 Italian children diagnosed with specific learning disorder (SLD) and an Italian normative sample of typically-developing children (with the exclusion of IQ

BACKGROUND The Wechsler Intelligence Scale for Children - Fourth Edition often produces floor effects in individuals with intellectual disability. Calculating respondents' Z or age-equivalent scores has been claimed to remedy this problem. METHOD The present study applied these methods to the Wechsler Intelligence Scale for Children - Fourth Edition scores of 198 individuals diagnosed with intellectual disability. Confirmatory factor analysis and profile analysis were conducted using a Bayesian approach. RESULTS The intelligence structure in intellectual disability resembled the one previously reported for typical development, suggesting configural but not metric invariance. When Z or age-equivalent scores (but not traditional scaled scores) were used, the average profile resembled the one previously reported for other neurodevelopmental disorders. CONCLUSIONS Both methods avoided any floor effects, generating similar but not identical profiles. Despite some practical and conceptual limitations, age-equivalent scores may be easier to interpret. This was true even for a subgroup of individuals with more severe disabilities (mean IQ

Intelligence measures are typically used in the assessment of children with autism spectrum disorders (ASD), but there is a paucity of research on the implications of such testing. In the present study, we examined children with ASD using two of the most largely adopted instruments, i.e., the WISC-IV, arguably the most utilized scale in the world; and the Leiter-3, a nonverbal scale that also excludes, from the IQ calculation, working memory and processing speed, which are points of weakness in ASD. Results showed that IQ and indices of these two batteries are strongly correlated. However, the WISC-IV IQ might underestimates the potential of children with ASD, particularly in children with a low functioning profile. These hold true for both the full scale IQ and three out of four indices of the WISC-IV, with remarkable implications for both assessment and treatment of these children. Practitioners working with children with ASD should be aware that the battery that they are using might severely affect the estimation of these children's potential.

Successful reading demands the ability to combine visual-phonological information into a single representation and is associated with an efficient short-term memory. Reading disability may consequently involve an impaired working memory binding of visual and phonological information. The present study proposes two span tasks for assessing visual-phonological working memory binding. The tasks involved memorizing cross-modal associations between nonsense figures and nonwords, and they were administered, with other working memory measures, to children with and without a reading disability. The tasks required recognizing which figure was associated with a given nonword and recalling which nonword was associated with a given figure. Children with a reading disability had a similar significant deficit in both cross-modal binding tasks when compared with the control children, and the difference remained significant even after controlling for other verbal and nonverbal working memory measures. The cross-modal binding tasks described here seem to capture a core aspect of working memory associated with reading and may be a useful procedure for assessing reading disabilities.

The present study aimed to investigate L2 spelling skills in Italian children by administering an English word dictation task to 13 children with dyslexia (CD), 13 control children (comparable in age, gender, schooling and IQ) and a group of 10 children with an English learning difficulty, but no L1 learning disorder. Patterns of difficulties were examined for accuracy and type of errors, in spelling dictated short and long words (i.e. disyllables and three syllables). Notably, CD were poor in spelling English words. Furthermore, their errors were mainly related with phonological representation of words, as they made more ‘phonologically’ implausible errors than controls. In addition, CD errors were more frequent for short than long words. Conversely, the three groups did not differ in the number of plausible (‘non-phonological’) errors, that is, words that were incorrectly written, but whose reading could correspond to the dictated word via either Italian or English rules. Error analysis also showed syllable position differences in the spelling patterns of CD, children with and English learning difficulty and control children. Copyright © 2016 John Wiley & Sons, Ltd.

It has been hypothesized that learning disabled children meet short-term memory (STM) problems especially when they must bind different types of information, however the hypothesis has not been systematically tested. This study assessed visual STM for shapes and colors and the binding of shapes and colors, comparing a group of children (aged between 8 and 10 years) at risk of non-verbal learning disabilities (NLD) with a control group of children matched for general verbal abilities, age, gender, and socioeconomic level. Results revealed that groups did not differ in retention of either shapes or colors, but children at risk of NLD were poorer than controls in memory for shape-color bindings.

Individuals with high vs. low sensation seeking respond to and remember emotional events in different ways. The present study investigates how high vs. low sensation seekers differ in memory performance for emotional events. Participants were presented with a series of pictures depicting everyday events, some of which had an emotional outcome, and subsequently administered a recognition task. Results showed that high vs. low sensation seekers differed in memory performance for episodes with negative outcome, such that performance was better in low sensation seekers. It is suggested that heightened aversive reactions to negative stimuli may improve memory for scripted episodes in low sensation seekers, while high sensation seekers may be motivated to avoid consideration of events that had a negative outcome.

Emotional disorders have been related with attentional and memory biases, especially for emotional material. Recent research has shown that depression, dysphoria and high internalizing traits are related with an increase of false memories for negative events. However, it is not clear whether anxiety alone may imply the same effect and whether it applies to all emotional events or only negative ones. The present study examined these questions by using a paradigm based on pictorial scripted material to analyze inferential memory errors for negative, positive and neutral everyday events in high-anxious vs. control young adults. Results showed an increase in negative (but not positive) inferential false memories in high-anxious individuals, even after controlling for depression level. On the contrary, negative material reduced false memories in control participants, further supporting previous research. It is concluded that high trait anxiety enhances elaboration of negative emotional material, which eventually leads to misremember causal antecedents of negative events as previously experienced while they were only inferred.

The ability to assess and monitor one’s own understanding of a written text is fundamental for learning and academic achievement. In the current paper, postdictive monitoring of text comprehension (i.e., the ability to judge the accuracy of responses previously given to a reading comprehension test) was investigated in both typically developing (TD) children and children with reading comprehension difficulties. Children from primary school (3rd to 5th grade) and secondary school (6th to 8th grade) participated in the study (N = 245). They were administered standardized tasks for reading comprehension, in which they had to read two texts and answer 12 multiple-choice questions after each text; subsequently, they had to provide postdictive judgments evaluating their performance: for each answer they had to select whether they judged it as correct, incorrect or whether they were uncertain. Two scores were calculated: Bias score, indicating the difference between metacognitive judgments of accuracy and actual performance; and Accurate estimation, indicating the sum of correct answers judged as “correct” and incorrect answers judged as “incorrect.” Results showed that primary school children were more overconfident than secondary school children and made fewer Accurate estimations especially for “correct” responses. Furthermore, the consideration of a group of children with reading comprehension difficulties showed that these failures are linked to worse metacognitive monitoring ability of comprehension performance in comparison not only to age-matched controls but also to the TD group of third-graders. Implications for learning and achievement are discussed.

Introduction: Preschoolers with attention-deficit/hyperactivity disorder (ADHD) have been found to exhibit impairments on neuropsychological measures of working memory (WM). As WM is an important predictor of future learning abilities, early intervention could help to prevent severe problems. The purpose of this research was to ascertain the efficacy of an intervention for training WM in 5-year-old children with symptoms of ADHD. Method: Thirty-four children with symptoms of ADHD were randomly divided into two groups: One was assigned to the WM training condition, and the other continued normal class activities. The training was provided at school in small groups that also included typically developing children. Results: The trained group showed a significant improvement in tasks measuring their WM and other controlled processes at conclusion of study, whereas no significant improvement was found in the control group. Conclusions: We concluded that early intervention on WM may be effective in chil...

Many children fail in geometric learning, but factors underlying these failures have not been explored in detail. The present study addresses this issue by comparing fifth and sixth-grade children who had good or poor geometric learning, and were otherwise comparable on verbal intelligence, gender and age. Results showed that children with poor geometric learning have deficits in both arithmetic and geometric problem solving but they are more impaired in the latter. Results also showed that poor geometric learners have weaknesses in working memory, calculation, and visuospatial mental imagery. The results from logistic regressions pointed out that mental imagery skills and arithmetic problem solving ability had the highest discriminatory power in distinguishing between the two groups. Theoretical and practical implications of this research for designing interventions to help poor geometric learners are discussed. © 2018 Elsevier Inc.

Adults produce fewer inferential false memories for scripted events when their conclusions are emotionally charged than when they are neutral, but it is not clear whether the same effect is also found in children. In the present study, we examined this issue in a sample of 132 children aged 6-12 years (mean 9 years, 3 months). Participants encoded photographs depicting six script-like events that had a positively, negatively, or a neutral valenced ending. Subsequently, true and false recognition memory of photographs related to the observed scripts was tested as a function of emotionality. Causal errors-a type of false memory thought to stem from inferential processes-were found to be affected by valence: children made fewer causal errors for positive than for neutral or negative events. Hypotheses are proposed on why adults were found protected against inferential false memories not only by positive (as for children) but also by negative endings when administered similar versions of the same paradigm.

The present study was devoted to test the validity, of the Italian adaptation of the Motor Observation Questionnaire for Teachers (MOQ-T, Schoemaker, Flapper, Reinders-Messelink, & De Kloet, 2008) as a fast screening instrument, based on teachers' ratings, for detecting developmental coordination disorders symptoms and to study its relationship with praxic and visuospatial working memory deficits. In a first study on a large sample of children, we assessed the reliability and structure of the Italian adaptation of the MOQ-T. Results showed a good reliability of the questionnaire and a hierarchical structure with two first-order factors (reflecting motor and handwriting skills), which are influenced by a second-order factor (general motor function) at the top. In a second study, we looked at the external validity of the MOQ-T and found that children with symptoms of Developmental Coordination Disorder (children with high scores on the MOQ-T) also had difficulty reproducing gestures, either imitating others or in response to verbal prompts. Our results also showed that children with high MOQ-T scores had visuospatial WM impairments. The theoretical and clinical implications of these findings are discussed. (C) 2014 Elsevier Ltd.

OBJECTIVE Research suggests that metacognitive beliefs may be involved in psychological distress and even in the pathogenesis of emotional disorders. The present research is a first attempt to investigate how certain metacognitive aspects operate as favorable or adverse factors influencing subjective wellbeing (SWB) in the parents of children with cancer. METHOD Thirty parents of children being treated for cancer completed questionnaires on their metacognitive beliefs (Metacognition Questionnaire), sensitivity to autobiographical memory, and self-reported measures of positive and negative affect (Positive and Negative Affect Schedule). Results in the study group were compared with those obtained from 36 control parents of children being treated for acute, not life-threatening illnesses (hospitalized control group) and from 30 control parents of healthy children (healthy control group). RESULTS Parents in both the study group and the hospitalized control group reported less SWB than the healthy control group. Most important, metacognitive aspects explained up to 77% of the variance in SWB in parents of children with cancer, as opposed to only 23% in hospitalized control group and 33% in the healthy control group. CONCLUSION Differentmetacognitive aspects have a crucial role—both negative and positive—inSWB of parents of children with cancer. It is suggested that the psychological support for parents copingwith a child suffering from oncological disease should assess such aspects and try to address them in clinical practice.

Although geometry is one of the main areas of mathematical learning, the cognitive processes underlying geometry-related academic achievement have not been studied in detail. This study explored the relationship among working memory (WM), intelligence (g factor), and geometry in 176 typically developing children attending school in their fourth and fifth grades. Structural equation modeling showed that approximately 40% of the variance in academic achievement and in intuitive geometry (which is assumed to be independent of a person's cultural background) was explained by WM and the g factor. After taking intelligence and WM into account, intuitive geometry was no longer significantly related to academic achievement in geometry. We also found intuitive geometry to be closely related to fluid intelligence (as measured by Raven's colored progressive matrices) and reasoning ability, whereas academic achievement in geometry depended largely on WM. These results were confirmed by a series of regressions in which we estimated the contributions of WM, intelligence, and intuitive geometry to the unique and shared variance explaining academic achievement in geometry. Theoretical and educational implications of the relationship among WM, intelligence, and academic achievement in geometry are discussed.

The effects of warning on false recognition and associated subjective experience of false recollection and familiarity were investigated in 7- to 13-year-old children and young adults (N = 259) using the Deese-Roediger-McDermott (DRM) paradigm. Two warning conditions (warning with an example of a critical lure and warning without an example of a critical lure) were compared to a control condition, in which no warning was received. We found that 7- to 8-year-olds exhibited higher false recognition in the warning-with-example condition compared with the control condition; in contrast, 12- to 13-year-olds and young adults exhibited reduced false recognition in the warning-with-example condition. No effect of warning was observed in 10- to 11-year-olds. The subjective experience associated with false memories was similar across ages. In contrast, age-related increases in subjective recollection were found for true memories. The processes that enhance or suppress false memories during development are discussed.

This study examined the involvement of verbal and visuo-spatial domains in solving addition problems with carrying in a sample of children diagnosed with developmental dyscalculia (DD) divided into two groups: (i) those with DD alone and (ii) those with DD and dyslexia. Age and stage matched typically developing (TD) children were also studied. The addition problems were presented horizontally or vertically and associated with verbal or visuo-spatial information. Study results showed that DD children's performance on mental calculation tasks was more impaired when they tackled horizontally presented addition problems compared to vertically presented ones that are associated to verbal domain involvement. The performance pattern in the two DD groups was found to be similar. The theoretical, clinical and educational implications of these findings are discussed.

Introduction Research has shown that lay people, and even psychologists, may have distorted knowledge about memory functioning. May different study programs in psychology influence their ideas? Objective(s) The study was aimed at evaluating psychology students’ and psychology professors’ knowledge about memory and factors potentially affecting the accuracy of episodic memory reports in clinical and legal contexts. Method A questionnaire was administered to introductory and advanced students of psychology enrolled at different curricula – experimental psychology and clinical psychology with a psychoanalytical orientation – and to professors teaching the courses in the same curricula. Results Results showed that advanced students and professors in experimental psychology have higher general knowledge of factors influencing memory performance than their peers, including memory issues of particular relevance to clinical psychology; no difference between the curricula was found for the introductory students. Conclusion The results are discussed in terms of the risks that the lack of knowledge on memory functioning of the psychologists with a psychodynamic orientation may have in producing wrong reports in forensic contexts.

The present study investigates intraindividual variability (IIV) in the Color-Stroop test and in a simple reaction time (SRT) task. Performance level and variability in reaction times (RTs)-quantified with different measures such as individual standard deviation (ISD) and coefficient of variation (ICV), as well as ex-Gaussian parameters (mu, sigma, tau)-were analyzed in 24 children with attention deficit/hyperactivity disorder (ADHD) and 24 typically developing children (TDC). Children with ADHD and TDC presented equivalent Color-Stroop interference effects when mean RTs were considered, and the two groups did not differ in the SRT task. Interestingly, compared to TDC, children with ADHD were more variable in their responses, showing increased ISD and ICV in the Color-Stroop interference condition and in the SRT task. Moreover, children with ADHD exhibited higher tau values-that is, more frequent abnormally long RTs-in the Color-Stroop interference condition than did the TDC, but comparable tau values in the SRT, suggesting more variable responses. These results speak in favor of a general deficit in more basic and central processes that only secondarily may affect the efficiency of inhibitory processes in children with ADHD. Overall the present findings confirm the role of IIV as a cornerstone in the ADHD cognitive profile and support the search for fine-grained analysis of performance fluctuations.

This study examined forward and backward recall of locations and colours and the binding of locations and colours, comparing typically developing children - aged between 8 and 10 years - with two different groups of children of the same age with learning disabilities (dyslexia in one group, non-verbal learning disability [NLD] in the other). Results showed that groups with learning disabilities had different visuospatial working memory problems and that children with NLD had particular difficulties in the backward recall of locations. The differences between the groups disappeared, however, when locations and colours were bound together. It was concluded that specific processes may be involved in children in the binding and backward recall of different types of information, as they are not simply the resultant of combining the single processes needed to recall single features.

It has been argued that children with dyslexia (DC) are poor at learning a foreign language (L2) and, in particular, reading foreign words. This assumption is so general that an Italian law (law 170, October, 2010) has established that DC may be completely exempted from foreign language learning and, in any case, should not be engaged in tuition via written material. However, evidence of L2 difficulties of DC is scarce and, in particular, absent for Italian children learning English. This absence of data is problematic, as it precludes information on the pattern of weaknesses and strengths, which could be found in DC. The present paper assessed these issues by administering an English word and pseudoword reading test to 23 DC and to 23 control children, matched for age, gender, schooling and IQ. The patterns of difficulties were examined individually for accuracy and speed, and the role of measures of native (L1) competence in L2 difficulties was also taken into account. Results confirmed that Italian DC are also poor in reading English words. However, they are accurate in reading pseudowords, suggesting that they have assimilated English pronunciation rules. Difficulties in L2 were, to some extent, but not completely, explained by difficulties in reading in L1.

The present experiment was conducted to investigate whether negative emotionally charged and arousing content of to-be-remembered scripted material would affect propensity towards memory distortions. We further investigated whether elaboration of the studied material through free recall would affect the magnitude of memory errors. In this study participants saw eight scripts. Each of the scripts included an effect of an action, the cause of which was not presented. Effects were either negatively emotional or neutral. Participants were assigned to either a yes/no recognition test group (recognition), or to a recall and yes/no recognition test group (elaboration + recognition). Results showed that participants in the recognition group produced fewer memory errors in the emotional condition. Conversely, elaboration + recognition participants had lower accuracy and produced more emotional memory errors than the other group, suggesting a mediating role of semantic elaboration on the generation of false memories. The role of emotions and semantic elaboration on the generation of false memories is discussed.

E noto che la memoria e un’abilita molto sensibile all’invecchiamento, tuttavia in letteratura sono presenti numerose evidenze della possibilita di potenziare tale funzione attraverso interventi di ri-attivazione cognitiva di vario tipo. Ancora controversi sono i risultati di questi interventi in termini di mantenimento e generalizzazione dei benefici ottenuti, dove un punto cruciale e rappresentato dagli aspetti metacognitivi e dalle convinzioni di autoefficacia degli anziani: il cambiamento di tali aspetti potrebbe difatti favorire l’applicazione delle strategie insegnate e quindi condurre ad un maggiore mantenimento e generalizzazione dei benefici. L’obiettivo di questo studio e presentare l’intervento strategico-metacognitivo "Lab.I Empowerment Cognitivo", proposto alla popolazione di Mestre dall’Antica Scuola dei Battuti. Tale intervento e stato effettuato con lo scopo di migliorare le prestazioni degli anziani in compiti di memoria e, al contempo, modificare gli atteggiamenti legati "al ricordare". Lo studio ha coinvolto 90 partecipanti. I risultati hanno evidenziato un miglioramento significativo sia nelle prove di memoria che nel livello di benessere psicologico percepito alla fine del training. Tali benefici si sono mantenuti al follow up condotto a 4 mesi dal termine del training. Con questo tipo di intervento si evidenzia l’importanza non solo dell’insegnamento delle strategie ma anche del cambiamento nelle convinzioni e atteggiamenti relativi alla memoria, al fine di modificare gli aspetti "caldi" e "freddi - della cognizione nell’invecchiamento.

This study examined the production of inferential false memories for complex pictorial stimuli and the implications of affective content in Alzheimer's disease (AD). A group of 24 AD patients and a group of 24 healthy older adults studied a sequence of pictures depicting stories that included positive, negative or neutral consequences of an unseen action, and then completed an old-new picture recognition test. The number of causal errors was higher in healthy older adults compared to AD patients but affective content attenuated the effect. Causal errors increased in AD patients when stories included affective (positive or negative) outcomes. In addition, negative content produced a larger number of errors than positive content across groups. This data confirms that although memory processing is poorer in AD, it is sensitive to affective content. Accordingly, the nature of affective false memory errors suggest the need to consider the use of affective information in the development of new cognitive training procedures.

Whereas a link between working memory (WM) and memory distortions has been demonstrated, its influence on emotional false memories is unclear. In two experiments, a verbal WM task and a false memory paradigm for negative, positive or neutral events were employed. In Experiment 1, we investigated individual differences in verbal WM and found that the interaction between valence and WM predicted false recognition, with negative and positive material protecting high WM individuals against false remembering; the beneficial effect of negative material disappeared in low WM participants. In Experiment 2, we lowered the WM capacity of half of the participants with a double task request, which led to an overall increase in false memories; furthermore, consistent with Experiment 1, the increase in negative false memories was larger than that of neutral or positive ones. It is concluded that WM plays a critical role in determining false memory production, specifically influencing the processing of negative material.

It has been argued that there may be a higher proportion of exceptional intelligence profiles and giftedness among children with learning disorders (LD) than among typically developing (TD) children, but this impression is only based on anecdotal evidence concerning famous individuals. In a large dataset of 1413 intellectual profiles of children with a diagnosis of LD (assessed with the WISC-IV scale), the proportion of children with an overall intelligence quotient higher than 130 was

International audience; The purpose of the present study was to test the efficacy of a working memory (WM) training in elderly people, and to compare the effects of a WM training based on an adaptive procedure with one combining the same procedure with the use of a strategy, based on the construction of visual mental images. Eighteen older adults received training with a WM task (the WM group), another 18 received the same WM training and were also taught to use a visual imagery strategy (the WM + Strategy group), and another 18 served as active controls. Training-related gains in the WM (criterion) task and transfer effects on measures of verbal and visuospatial WM, short-term memory (STM), processing speed, and reasoning were considered. Training gains and transfer effects were also assessed after 6 months. After the training, both the trained groups performed better than the control group in the WM criterion task, and maintained these gains 6 months later; they also showed immediate transfer effects on processing speed. The two trained groups also outperformed the control group in the long term in the WM tasks, in one of the STM tasks (backward span task), and in the processing speed measure. Long-term large effect sizes were found for all the tasks involving memory processes in the WM + Strategy group, but only for the processing speed task in the WM group. Findings are discussed in terms of the benefits and limits of teaching older people a strategy in combination with an adaptive WM training.

The present study analyzes whether and how the most common diagnoses within the specific learning disorder (SLD) category are characterized by different intellectual profiles. The issue is relevant to the current debate on the unitary versus decomposable nature of the SLD category and may help define specific interventions. Intellectual profiles were obtained using the Wechsler Intelligence Scale for Children–IV (WISC-IV) on 1,049 children diagnosed with SLD using the ICD-10 codes. Four major subsamples were compared: reading disorder, spelling disorder, disorder of arithmetical skills, and mixed disorder of scholastic skills. The four main WISC-IV indexes (verbal comprehension, perceptual reasoning, working memory, and processing speed) were considered. Results showed that all SLD subgroups share similar weaknesses in working memory and processing speed, but they also showed that the subgroups are characterized by partly different intellectual profiles. These specificities should be considered in the definition of SLD.

A study was conducted on the involvement of visuospatial working memory (VSWM) in intuitive geometry and in school performance in geometry at secondary school. A total of 166 pupils were administered: (1) six VSWM tasks, comprising simple storage and complex span tasks; and (2) the intuitive geometry task devised by Dehaene, Izard, Pica, and Spelke (2006), which distinguishes between core, presumably innate, and culturally-mediated principles of geometry; and (3) a task measuring academic achievement in geometry. Path analysis models showed that some VSWM components support culturally-mediated principles of geometry, whereas no VSWM component is related to the core principles of geometry. A complex VSWM task requiring the manipulation of visual information as well as core and culturally-mediated principles of geometry directly predicted academic achievement in geometry. Our results are discussed in terms of the role of VSWM in learning geometry.

Recent results of international assessment programs (e.g., PISA) have shown a large difference in high school students' performance between northern and southern Italy. On this basis, it has been argued that the discrepancy reflects differences in average intelligence of the inhabitants of regions and is associated with genetic factors ( Lynn, 2010a , Lynn, 2012 ). This paper provides evidence in contrast to this conclusion by arguing that the use of PISA data to make inferences about regional differences in intelligence is questionable, and in any case, both PISA and other recent surveys on achievement of North and South Italy students offer some results that do not support Lynn's conclusions. In particular, a 2006–2009 PISA data comparison shows a relevant decrease in the North–South difference in only three years, particularly evident in the case of a single region (Apulia). Other large surveys (including INVALSI-2011) offer different results; age differences suggest that schooling could have an important role.

Time-based prospective memory (PM) is the ability to remember to perform an intended action at a given time in the future. It is a competence that is crucial for effective performance in everyday life and may be one of the main causes of problems for individuals who have difficulty in planning and organizing their life, such as children with attention deficit/hyperactivity disorder (ADHD). This study systematically examines different aspects of time-based PM performance in a task that involves taking an action at a given future time in a group of 23 children with ADHD who were compared with a matched group of typically-developing (TD) children. The children were asked to watch a cartoon and then answer a questionnaire about its content (ongoing task). They were also asked to press a key every 2 minutes while watching the cartoon (PM task). The relationships of time perception and verbal working memory with PM performance were examined by administering appropriate tasks. The results showed that the children with ADHD were less accurate than the TD children in the PM task and exhibited less strategic time-monitoring behavior. Time perception was found to predict PM accuracy, whereas working memory was mainly involved in time-monitoring behavior, but this applied more to the TD group than to the ADHD group, suggesting that children with ADHD are less able to use their cognitive resources when meeting a PM request.

Enhanced semantic processing is associated with increased false recognition of items consistent with studied material, suggesting that children with poor semantic skills could produce fewer false memories. We examined whether memory errors differed in children with Attention Deficit/Hyperactivity Disorder (ADHD) and controls. Children viewed 18 photographs for each of 4 scripts (e.g., eating at a restaurant). A recognition test followed which included old and new photographs, some of which presenting script consistent information and others depicting the cause (e.g., knocking over a glass of coke) of an effect actually viewed during encoding (wiping the table at the restaurant). Children with ADHD exhibited lower false recognition for script-consistent photographs and were more confident in their errors than controls.

Objective: It has been argued that ADHD characteristics children have difficulties in selecting the best strategy when they accomplish cognitive tasks. The detrimental influence of these poor strategy skills may be crucial for several aspects of academic achievement such as mathematical learning. Method: Fourth- and fifth-grade children with ADHD symptoms and matched controls were asked to select the better of two rounding strategies in a computational estimation task (i.e., finding the best estimate of two-digit addition problems). Results: (a) Both control and ADHD children correctly executed a selected strategy, (b) ADHD children selected the best strategy less often than controls, (c) ADHD took more time to estimate sums of two-digit addition problems and provided poorer estimates, and (d) different factors predicted best strategy selections in each group. Conclusion: These findings have important implications for further understanding the sources of differences in cognitive performance between ADHD and control children. (J. of Att.

The development of subjective recollection was investigated in participants aged 6–18 years. In Experiment 1 (N = 90), age-related improvements were found in understanding of the subjective experience of recollection, although robust levels of understanding were observed even in the youngest group. In Experiment 2 (N = 100), age-related differences were found in subjective recollection during a memory task, suggesting development not only in the ability to reflect on memory states, but also in the informational basis of subjective recollection. Lower understanding of memory states was associated with increased propensity to claim recollection. These results indicate that subjective recollection develops considerably during childhood and suggest that the development of metamemory supports this capacity.

The need for a battery for testing adult dyslexia, and especially university students, is being increasingly recognized in view of the increased number of adult requests for a dyslexia examination in relation to both assistance and protection from discrimination. The present study examines the discriminative validity of a battery we have developed—the Battery for the Assessment of Reading and Writing in Adulthood—through comparison of the performance of 24 university students with a history of severe developmental dyslexia and 99 controls. All the reading, writing, lexical decision and spelling tasks of the battery, except omissions in a lexical decision task and reading comprehension, showed a good discriminatory power. In addition, use of just two of these tasks (fluency in reading a text and spelling under articulatory suppression) gave 87% sensitivity and 97% specificity. Our results confirm that in transparent languages, measures of phonological automaticity are the best indexes of reading decoding competence, particularly in adults.

Visuospatial working memory and its involvement in arithmetic were examined in two groups of 7- to 11-year-olds: one comprising children described by teachers as displaying symptoms of nonverbal learning difficulties ( N = 21), the other a control group without learning disabilities ( N = 21). The two groups were matched for verbal abilities, age, gender, and sociocultural level. The children were presented with a visuospatial working memory battery of recognition tests involving visual, spatial-sequential and spatial-simultaneous processes, and two arithmetic tasks (number ordering and written calculations). The two groups were found to differ on some spatial tasks but not in the visual working memory tasks. On the arithmetic tasks, the children with nonverbal learning difficulties made more errors than controls in calculation and were slower in number ordering. A discriminant function analysis confirmed the crucial role of spatial-sequential working memory in distinguishing between the two groups. Results are discussed with reference to spatial working memory and arithmetic difficulties in nonverbal learning disabilities. Implications for the relationship between visuospatial working memory and arithmetic are also considered.

Background Despite the critical role attributed to working memory (WM) updating for executive functions and fluid intelligence, no research has yet been carried out on its specific role in the vital case of fluid intelligence weakness, represented by indi- viduals with intellectual disability (ID). Further- more, the relationship between updating and other WM functions has not been considered in depth. Method The current study examines these areas by proposing a battery of WM tasks (varying in degree of active attentional control requested) and one updating task to groups of ID individuals and typi- cally developing children, matched for fluid intelli- gence performance. Results Comparison between the group of ID indi- viduals and a group of children showed that, despite being matched on the Raven test, the updat- ing measure significantly differentiated the groups as well as the WM complex span. Furthermore, updating proved to be the task with the greatest power in discriminating between groups. Conclusions Our results confirm the importance of the demand for active attentional control in explain- ing the role of WM in fluid intelligence perfor- mance, and in particular show that updating information in WM plays an important role in the distinction between typically developing children and ID individuals.

A large body of evidence shows that many of the academic difficulties Attention Deficit Hyperactivity Disorder (ADHD) children have may be related to their problems in executive control. However, the particular case of expressive writing has not been deeply explored. The present study examines the typical school exercise of writing a letter. Participants were 33 third, fourth, and fifth graders referred by teachers for the presence of ADHD symptoms plus 33 controls. The task consisted of describing an aspect of their life in the form of a letter. Texts of ADHD children were poorer than those of the controls for structure, vocabulary, grammar, length, and accuracy. Furthermore, the difference persisted even when a guide was used to support the writing task. However, the two groups were not significantly different in a metacognitive test measuring knowledge on critical factors affecting expressive writing. Results show that ADHD children may encounter severe difficulties in expressive writing that are not due to differences in knowledge about how to write. Educational implications are discussed.
