Creative idea generation engages complex cognitive functions such as working memory capacity (WMC). The relationship between creativity and WMC has remained inconsistent due to the lack of experime...

Emotional conflict adaptation is an important process of cognitive control in human behavioral regulation. The face-word Stroop task and the emotional Simon task were employed to explore the correlation between fluid intelligence and neural processes of emotional conflict adaptation using event-related potential (ERP) techniques. Thirty-two intellectually average children (mean age of 10.72 years) and thirty-four intellectually gifted children (mean age of 10.86 years) participated in the present study. The behavioral results indicated that both intellectually gifted and average children showed reliable emotional conflict adaptation effects (CAEs) on reaction times (RTs) and error rates. However, the two IQ groups differed in the magnitude of error rates during emotional conflict adaptation. The electrophysiological results further revealed that the IQ differences in emotional conflict adaptation were mainly associated with emotional conflict detection processes as demonstrated by the frontal N2-CAE values. The two IQ groups did not differ in early P3 or late P3 responses during emotional conflict resolution processes. The gifted and average children showed different patterns during cognitive control processes when facing emotional Simon conflicts and emotional Stroop conflicts. The current study emphasizes the importance of frontal function during cognitive control of emotional information from the perspective of individual differences.

This study investigated the relationships between parental responsiveness, teaching responsiveness, and creativity, as well as the mechanism underlying these associations. We collected data from 584 Chinese college students via convenience sampling method and used self-report scales to measure their perceived parental responsiveness, teaching responsiveness, creative self-efficacy, and creativity. We employed structural equation modeling (SEM) to examine the relationships among these variables and the mediation effect. The results revealed that both parental responsiveness and teaching responsiveness were positively related to student creativity. Moreover, creative self-efficacy mediated the relationships of parental responsiveness, teaching responsiveness, and creativity. The findings highlight the significance of responsiveness from parents and teachers on student creativity and verify the potential mediating role of creative self-efficacy. These findings suggest that teachers and parents can foster creativity by providing warm and supportive responses to students’ creative needs.

This study examined the effects of fluid intelligence and trait emotional intelligence (trait EI) on academic performance in primary school-aged intellectually gifted and average children (8–11 years of age). One hundred and four average children and eighty gifted children were administered a Raven’s Standard Progressive Matrices and a Trait Emotional Intelligence Questionnaire-Child Form. The results demonstrated that intellectually gifted children showed better academic performance than did average children in math, Chinese and English. Fluid intelligence and trait EI played different roles in predicting gifted and average children’s academic performance, particularly in math and Chinese. Specifically, gifted children’s academic performance was associated only with fluid intelligence, whereas average children’s academic performance was related to both fluid intelligence and trait EI; trait EI had an incremental validity after controlling for fluid intelligence in predicting the average children’s academic performance. The present study enhances our understanding of how cognitive and emotional abilities interact in intellectually gifted and average children’s academic performance.

Objective This study explored behavioral and electrophysiological age-related changes in conflict adaptation to emotional stimuli among children, adolescents, and young adults. Method Children (N = 35, Mage = 10.72 years), adolescents (N = 35, Mage = 13.34 years), and young adults (N = 30, Mage = 21.82 years) were administered cognitive control tasks on emotional stimulus-stimulus (S-S) conflict and stimulus-response (S-R) conflict while event-related potential (ERP) signals were recorded. Results The behavioral results (response time [RT] and error rate) showed that all age groups exhibited reliable conflict adaptation effect (CAE) to emotional stimuli, and conflict adaptation performance improved with age. A similar developmental pattern was observed when the ERP magnitudes of the CAE to emotional stimuli (N2 amplitude, N2 latency, and early P3 latency) were compared. Participants performed better on conflict adaptation to emotional S-S stimuli when compared with the S-R stimuli (RT-CAE, N2 amplitude-CAE and late P3 amplitude-CAE), and only children performed better conflict adaptation to emotional S-S stimuli than on S-R stimuli in terms of error rates. Conclusion Children, adolescents, and young adults all presented reliable behavioral and electrophysiological conflict adaptation to emotional stimuli, and participants exhibited improved performance on conflict adaptation with age across the 3 age groups in emotional contexts. Moreover, all the age groups showed distinct cognitive control of emotional S-S and S-R conflict, and conflict adaptation to emotional S-S stimuli may mature earlier than S-R conflict. This study offers insight into how the processing of emotional stimuli affects cognitive control processes from a developmental perspective.

Recently, the integrated control hypothesis (Lu et al., 2020) was proposed to explain the relationship between fluid intelligence (Gf) and attentional resource allocation. This hypothesis suggested that individuals with higher Gf tend to flexibly and adaptively allocate their limited resources according to the task type and task difficulty rather than simply exert more or fewer resources in any conditions. To examine this hypothesis, the present study used electroencephalogram (EEG) indicators (i.e., frontal theta-ERS and parietal-occipital alpha-ERD) as the measurement of participants’ resource allocation during the exploration task and exploitation task with different difficulties. The results found that higher Gf individuals tend to allocate fewer resources in all difficulty levels in the exploitation task compared to average Gf participants. In contrast, in the exploration task, higher Gf participants would allocate more resources in the medium- and high-difficulty levels than average Gf participants, but this phenomenon was only found in males. These findings provided supportive evidence for the integrated control hypothesis that flexible and adaptive attentional control ability are important characteristics of human intelligence.

Reward is deemed a performance reinforcer. The current study investigated how social and monetary reward anticipation affected cognitive control in 39 children, 40 adolescents, and 40 adults. We found that cognitive control performance improved with age in a Simon task, and the reaction time (RT) was modulated by the reward magnitude. The conflict monitoring process (target N2 amplitudes) of adolescents and the attentional control processes (target P3 amplitudes) of adolescents and adults could be adjusted by reward magnitude, suggesting that adolescents were more sensitive to rewards compared to children. Reward magnitudes influenced the neural process of attentional control with larger P3 in congruent trails than that in incongruent trials only in low reward condition. The result of hierarchical drift-diffusion model indicated that children had slower drift rates, higher decision threshold, and longer non-decision time than adolescents and adults. Adolescents had faster drift rates in monetary task than in social task under the high reward condition, and they had faster drift rates under high reward condition than no reward condition only in the monetary task. The correlation analysis further showed that adults' non-decision time and decision threshold correlated with conflict monitoring process (N2 responses) and attentional control process on conflicts (P3 responses). Adolescents' drift rates associated with neural process of attentional control. The current study reveals that reward magnitude and reward type can modulate cognitive control process, especially in adolescents.

To clarify the effects of individual differences in fluid intelligence (Gf) on attentional resource allocation, the present study proposes a new hypothesis (i.e., the integrated control hypothesis) based on previous studies and provides preliminary empirical evidence through a pupillometry study. The results showed that both task type and task difficulty play crucial roles in the relationship between Gf and attentional resource allocation when participants perform visuospatial-domain tasks. In particular, in the exploitation task, higher Gf individuals allocated fewer attentional resources than those with average Gf at all the difficulty levels. In contrast, in the exploration task, those with higher intelligence allocated equivalent resources in the low- and medium-difficulty trials and more resources in the high-difficulty trials; this phenomenon was more significant among the male subjects. In conclusion, this study suggests that high Gf individuals tend to control their attention state in tasks with diverse demands, allowing them to dynamically optimize the use of attentional resources and flexibly adapt to changing conditions.

Children are found to exhibit high degrees of delay discounting compared with adults in many delay discounting studies. However, the temporal dynamics of the differences behind the behaviors are not well known. In this study, we chose two age groups of participants and adopted event-related potential (ERP) techniques to investigate the neural dynamic differences between children and adults during delay discounting processes. Behavioral findings showed that children discounted more than adults and chose more immediate choices. Electrophysiological findings revealed that children exhibited longer neural processing (longer P2 latency) than adults during the early detection and identification phase. Children showed less cognitive control (smaller N2 amplitude) than adults over the middle frontal areas, and they devoted more neural effort (larger P3 amplitudes) to making final choices than adults. The factors of reward amount and time delay could influence the development of delay discounting in male children.

Adolescence is an essential developmental period characterized by reward-related processes. The current study investigated the development of monetary and social reward processes in adolescents compared with that in children and adults; furthermore, it assessed whether adolescents had different levels of sensitivity to various types of rewards. Two adapted incentive delay tasks were employed for each participant, and event-related potentials (ERPs) were recorded. The behavioral results showed that both monetary and social rewards could motivate response speed, and participants were more accurate under the monetary reward condition than under the social reward condition. The behavioral performances of individuals increased with age. For the ERP data, the cue-P3, target-P2, target-P3 and feedback-related negativity (FRN) components were investigated to identify reward motivation, emotional arousal, attention allocation and feedback processing. Children and adolescents showed higher motivation (larger cue-P3) to rewards than adults. Adolescents showed larger emotional responses to rewards; that is, they had larger target-P2 amplitudes than adults and shorter target-P2 latencies than children. Children showed stronger emotional reactivity for monetary rewards than for social rewards. All age groups had stronger attentional control (larger target-P3) under the monetary reward condition than under the social reward condition. The present study sheds light on the neurodevelopment of reward processes in children, adolescents and adults and shows that various reward process stages demonstrate different age-related and reward-type-related characteristics.

This study investigated the inhibitory process of collaborative inhibition. An emotional Stroop task was manipulated three times after a group-recall task across three experiments. The results showed that, when participants performed an emotional Stroop task immediately after a group-recall task (Experiment 1) or between two subsequent individual-recall tasks after a group-recall task (Experiment 3), they were able to discriminate color information relating to studied but nonrecalled emotional stimuli more rapidly in the collaborative-recall condition than in the nominal-recall condition. This indicated that participants experienced a stronger inhibition effect in the former condition. However, when the emotional Stroop task was performed after the final individual-recall task (Experiment 2), there were no differences in discrimination between the conditions. These results suggest that the inhibition effect occurs immediately after the group-recall phase and lasts until the final individual-recall task is completed (4 minutes or longer in Experiment 3). It is therefore possible to discuss retrieval inhibition as an underlying mechanism of collaborative inhibition.

The education of gifted children is of considerable interest.The present study focused on the effect of enriched education on intellectually gifted children's attention. In the present study, 7-12-year-old children completed seven tests of attention (alertness, focused attention, divided attention, attentional switching, sustained attention, spatial attention, and supervisory attention) to investigate the differences among intellectually gifted children under different educational environments. The results showed that intellectually gifted children who received enriched education had better attentional performance than did intellectually gifted children who received standard education. The result affords theoretical support for gifted-education practice.

Previous researches have shown that people with higher fluid intelligence are more likely to detect the unexpected stimuli. The current study systematically explored the relationship between fluid intelligence and sustained inattentional blindness in children. In Experiment 1, we measured one hundred and seventy-nine 7-to-14-year-old children's fluid intelligence and sustained inattentional blindness. The results showed that fluid intelligence was negatively related to sustained inattentional blindness only in 7-to-8-year-old children. In Experiment 2, we explored sustained inattentional blindness in sixty children with high Raven's scores. We found that compared with children who have average Raven's scores aged 11-to-12 years old, children with high Raven's scores were unable to better avoid sustained inattentional blindness. In general, this research implies that the relation between fluid intelligence and sustained inattentional blindness is weak. Fluid intelligence could predict sustained inattentional blindness only when children do not have enough perceptual capacities to complete the primary task.

The authors examined sustained attention performance and PTSD symptoms in a sample of 281 orphans and non-orphans who experienced the Sichuan Earthquake in China. They hypothesized that the orphans had a higher possibility to risk for PTSD than non-orphans, and the former also might even tend to be more impulsive, allergic which might affect their basic cognitive skill-attention. The findings showed evidence of cognitive developmental stages, from vigilance to numbness and avoidance, in the continuous performance test (CPT) task by including pre-earthquake orphans. The post-earthquake orphans were still in a high level of vigilance and performed well in the CPT task when compared with the pre-earthquake orphans. The non-orphans with high possibility to risk for PTSD were the most concentrated and least impulsive. Given the potentially mutual relationship between sustained attention and posttraumatic stress disorder, careful consideration must be given to the treatment of traumatized children who present with PTSD symptoms. In accordance with practice guidelines, a duplex informant, duplex measure approach in the decision of educational plans for these children is strongly recommended.

Emotional intelligence is an important factor contributing to social adaptation. The current study investigated how salivary testosterone (T) and cortisol (C) levels, cognitive control of emotional conflict processing were associated with children’s emotional intelligence (EI). Thirty-four 10- to 11-year-old children were enrolled and instructed to complete questionnaires on emotional intelligence as well as empirical tasks of emotional flanker and Stroop with event-related potential (ERP) recordings. Saliva collection took place on another day without ERP tasks. Results showed that lower T and C levels were associated with higher accuracy in emotional conflict tasks, as well as better emotional intelligence (managing self emotions). In the Stroop task, higher T/C ratios were associated with greater congruency effects of N2 latencies, and lower cortisol levels correlated with stronger slow potential activities (SP). For girls, the correlation between cortisol and emotional utilization was mediated by the SP amplitudes on fearful conflicts in the flanker task (95% CI: −8.64, −0.54, p < 0.050). In conclusion, the current study found the relationship between cortisol and an emotional intelligence ability, emotional utilization, might be mediated by brain activities during emotional conflict resolution processing (SP responses) in preadolescent girls. Future studies could further investigate testosterone-cortisol interaction and its relation with cognitive control of emotion as underlying mechanisms of emotional intelligence.

Tonic pupil size and its variability are sensitive to cognitive abilities (such as fluid intelligence [Gf]) among individuals. The present study aimed to examine this relationship in a new sample set (i.e., adolescents aged 11-14 years) with several important factors considered. We conducted two task-free tasks (the blank-screen viewing task and the scene viewing task) to measure tonic pupil size and its variability in 11-14-year-old adolescents with different Gf levels and preliminarily tested the role of task type and stimuli's luminance on this relationship. The results found that high-Gf adolescents showed smaller tonic pupil size in both tasks but showed larger variability of tonic pupil size in the blank-screen viewing task. Task type and stimuli's luminance could influence tonic pupil size and its variability in different ways. Cognitive and underlying neural mechanisms of these results are discussed to provide an explanation and suggestions for future studies.

The SNARC (Spatial-Numerical Association of Response Codes) effect (i.e., a tendency to associate small / large magnitude numbers with the left / right hand side), is prevalent across the whole lifespan. Because the ability to relate numbers to space has been viewed as a cornerstone in the development of mathematical skills, the relationship between the SNARC effect and math skill has been frequently examined. The results remain largely inconsistent. Studies testing groups of people with very low or very high skill levels in math sometimes found relationships between SNARC and math skill. So far, however, studies testing such extreme math skill level groups were mostly investigating the SNARC effect in individuals revealing math difficulties. Groups with above average math skills remain understudied, especially in regard to children. Here, we investigate the SNARC effect in gifted children, as compared to normally developing children (overall n = 165). Frequentist and Bayesian analysis suggested that the groups did not differ from each other in the SNARC effect. These results are the first to provide evidence for the SNARC effect in a relatively large sample of gifted (and mathematically highly skilled) children. In sum, our study provides another piece of evidence for no direct link between the SNARC effect and mathematical ability in childhood.

This research investigated the individual behavioral and electrophysiological differences during emotional conflict adaptation processes in preschool children. Thirty children (16 girls, mean age 5.44 ± 0.28 years) completed an emotional Flanker task (stimulus-stimulus cognitive control, S-S) and an emotional Simon task (stimulus-response cognitive control, S-R). Behaviorally, the 5-year-old preschool children exhibited reliable congruency sequence effects (CSEs) in the emotional contexts, with faster response times (RTs) and lower error rates in the incongruent trials preceded by an incongruent trial (iI trial) than in the incongruent trials preceded by a congruent trial (cI trial). Regarding electrophysiology, the children demonstrated longer N2 and P3 latencies in the incongruent trials than in the congruent trials during emotional conflict control processes. Importantly, the boys showed a reliable CSE of N2 amplitude when faced with fearful target expression. Moreover, 5-year-old children showed better emotional CSEs in response to happy targets than to fearful targets as demonstrated by the magnitude of CSEs in terms of the RT, error rate, N2 amplitude and P3 latency. In addition, the results demonstrated that 5-year-old children processed S-S emotional conflicts and S-R emotional conflicts differently and performed better on S-S emotional conflicts than on S-R emotional conflicts according to the comparison of the RT-CSE and P3 latency-CSE values. The current study provides insight into how emotionally salient stimuli affect cognitive processes among preschool children.

The term “intellectually gifted rural-to-urban migrant children” refers to intellectually gifted children who are in migration from rural to urban areas. We compared performances on seven attention tasks among intellectually gifted (n = 26) and average (n = 30) rural-to-urban migrant and intellectually gifted urban children (n = 31). Our results showed that intellectually gifted rural-to-urban migrant children performed more correctly and faster on some attention tasks than did the intellectually average rural-to-urban migrant children, but they did not perform as well on some attention tasks as did the intellectually gifted urban children. Based on the attentional structures, it was evident the intellectually gifted rural-to-urban migrant children developed more mature than did either the intellectually gifted urban or the intellectually average rural-to-urban migrant children. This suggests the intellectually gifted rural-to-urban migrant children’s attention is overall superior to that of their...

The relationship between recognition memory and cognitive control is an important research topic. The current study investigated how conflict control influences an individual's emotional memory. During the encoding phase, participants were required to judge the affective valence of a Chinese Chengyu word (either positive or negative) in a modified Simon paradigm and to remember the word. Half of the words were presented in the congruent condition and the other half were displayed in the incongruent condition. During the retrieval phase, participants were instructed to make an 'old/new judgment' and decide whether the word had been presented previously. Electrophysiological responses were recorded using the event-related potential (ERP) technique. The behavioral results of retrieval processes showed that participants remembered more positive than negative words when they were encoded in the congruent condition. The electrophysiological results revealed that the retrieval of words encoded in the incongruent condition elicited less negative frontal negativity (FN) and early posterior negativity (EPN) amplitudes than those encoded in the congruent condition. The retrieval of words encoded in the incongruent condition induced greater late positive complex (LPC) amplitudes, relative to those encoded in the congruent condition on the left hemisphere. It was also observed that the recognition of positive words induced faster LPC responses than negative words when they were encoded in the incongruent condition. The present electrophysiological study illustrates that emotional memory processes may be affected by conflict control. (C) 2015 IBRO. Published by Elsevier Ltd. All rights reserved.

Two studies comparing Chinese and German samples by using work-related verbal creativity tasks examined the role of culture in creative expression thereby also exploring culture's potential influence on creativity judgements. In Study 1, German participants (N = 60) scored higher than Chinese respondents (N = 60) in a work-related unusual uses test on all objective creativity measures. Study 2 (Chinese: N = 59, German: N = 52) replicated these findings by applying an occupational creative problem-solving task evaluated by using the Consensual Assessment Technique with judges from China as well as Germany. We observed high consensus among judges of each country as well as between the two cultures. Both German and Chinese judges rated the German respondents’ outcomes higher on most creativity dimensions (e.g., originality). Overall, German judges provided lower ratings. Our research extends previous intercultural findings solely based on art-based creative performance to the occupational domain and indicates that higher creativity ascriptions toward the performance of Western people cannot be explained by assessments from Western raters.

Intelligence explains some variance in children's school achievement, but not all. Parental intrusive control behavior on children generally negatively correlates with children's school achievement, yet nothing has been done to examine the validity of this relation independent of intelligence and parental education. Child report has mainly been used as the parental control indicator, and parental report has rarely been explored. This study assessed the validity of the associations between two parental control indicators and children's school achievement independent of intelligence and parental education. In a sample of 310 German elementary school children, we found a correlation of .67 between parents' and children's perceptions of parents' control behavior. Independent of measured intelligence and parental education, parent-perceived control behavior was significantly associated adversely with school achievement. Child-perceived control did not predict school achievement when parent-perceived control was included in the model. Reasons for this pattern were discussed.

Collaborative inhibition refers to when people working together remember less than their predicted potential. The most common explanation for this effect is the retrieval-disruption hypothesis during collaborative recall. However, several recent studies have obtained conflicting results concerning this hypothesis. In the current study, item similarity was manipulated in Experiment 1 by requiring participants to study overlapping or non-overlapping unrelated wordlists. The unstructured instructions were then manipulated during a turn-taking recall task between conditions. The results showed that collaborative inhibition occurred for both overlapping and non-overlapping conditions. Subsequently, response competition during collaborative recall, in addition to item similarity, was manipulated in Experiment 2, and the results showed that when collaborative group members were instructed to recall in turn and monitor their partner’s recall (the medium- and high-response-competition conditions), collaborative inhibition occurred. However, no such effect was shown when collaborative group members were instructed not to communicate with each other, but to simply recall in turn while in a group (low-response-competition condition). Together, these results suggest that the conflicts between the findings of the aforementioned studies were probably caused by differing instructions, which induced response competition in collaborative settings. Aside from retrieval-disruption, other possible mechanisms underlying collaborative inhibition were also discussed.

We explored the development of attention among elementary school children. Three hundred and sixty-five primary school children aged 7–12 years completed seven attention tests (alertness, focused attention, divided attention, attentional switching, sustained attention, spatial attention, and supervisory attention). A factor analysis indicated that there was no stable construct of attention among 7- to 8-year-old children. However, from 9 years on, children’s attention could be separated into perceptual and executive attention. Notably, however, the attention types included in these two factors differed from those among adults.

Conflict control refers to an individual's goal-directed cognitive control and self-regulation of behavior. The neurodevelopment related to conflict control is crucial for the development of cognitive and emotional abilities in children. In the current study, preadolescent children and adults completed the Simon and Stroop tasks in emotional and non-emotional contexts with simultaneous electroencephalography recordings. The behavioral findings showed that adults had faster response speed and better conflict control performance compared to children. Children's accuracy was affected by the emotional context, whereby children had a lower accuracy in the emotional contexts compared to the non-emotional contexts. Adults had similar performances in both contexts. During the neural processes of conflict detection and conflict resolution, children had longer N2 latencies for conflict detection, and devoted more neural efforts with larger P3 amplitudes to execute resolution control on the conflicts than adults. Moreover, both age groups' reaction times (RT) were shorter in the Simon task than in the Stroop task in the non-emotional context, while, RTs were longer in the Simon task than in the Stroop task in the emotional context. Children showed larger P3 responses in the Simon task than in the Stroop task in the emotional contexts, while adults showed no such differences. The current findings demonstrate that children have immature neurodevelopment of conflict control compared to adults, and their cognitive control processes on conflicts were distracted by the emotional contexts. Children's emotional conflict control processes were also affected by the characteristic of conflict types, and they need to devote more neural effort to process Simon-like conflicts than Stroop-like conflicts compared to adults.

Posttraumatic stress symptoms in Chinese rural children and adolescents were examined after the May 2008 Wenchuan earthquake. Analysis showed that three factors were identified, namely, avoidance, intrusion, and arousal, resembling those in the studies with Western samples. Gender differences in posttraumatic stress symptoms were not significant. Moderate negative correlation coefficients between posttraumatic stress symptom scores and mental health scores were found, indicating that the more severe the posttraumatic stress symptoms, the worse the person's mental health.

The present study investigated the roles of cognitive (working memory, intelligence) and motivational variables (self-perceived ability, intrinsic value) in explaining school achievement. The sample consisted of N = 320 German elementary school children in the fourth grade. Working memory and intelligence were assessed in the classroom. Questionnaires including the motivational items were answered at home. Teachers provided midterm and endterm grades for the domains of German and Math. Using structural equation modeling, our main results indicated that across domains, both cognitive and motivational predictors explained substantial amounts of specific variance in school grades. The findings are, however, to some degree domain-specific in that cognitive variables were stronger predictors of Math (COG: beta = .59; MOT: beta = .41), whereas for German, motivational influences turned out to be better predictors (COG: beta = .34; MOT: beta = .67). Together, cognitive ability (including both WM and intelligence) and motivation (including self-perceived ability and intrinsic value) explained 75% and 71% of the variance in children's German and Math grades, respectively.

In general, intellectually gifted children perform better than non-gifted children across many domains. The present validation study investigated the speed with which intellectually gifted children process information. 184 children, ages 9 to 13 years old (91 gifted, M age = 10.9 yr., SD = 1.8; 93 non-gifted children, M age = 11.0 yr., SD = 1.7) were tested individually on three information processing tasks: an inspection time task, a choice reaction time task, an abstract matching task. Intellectually gifted children outperformed their non-gifted peers on all three tasks obtaining shorter reaction time and doing so with greater accuracy. The findings supported the validity of the information processing speed in identifying intellectually gifted children.

Inhibitory control (including response inhibition and interference control) develops rapidly during the preschool period and is important for early cognitive development. This study aimed to determine the training and transfer effects on response inhibition in young children. Children in the training group (N = 20; 12 boys, mean age 4.87 ± 0.26 years) played “Fruit Ninja” on a tablet computer for 15 min/day, 4 days/week, for 3 weeks. Children in the active control group (N = 20; 10 boys, mean age 4.88 ± 0.20 years) played a coloring game on a tablet computer for 10 min/day, 1–2 days/week, for 3 weeks. Several cognitive tasks (involving inhibitory control, working memory, and fluid intelligence) were used to evaluate the transfer effects, and electroencephalography (EEG) was performed during a go/no-go task. Progress on the trained game was significant, while performance on a reasoning task (Raven’s Progressive Matrices) revealed a trend-level improvement from pre- to post-test. EEG indicated that the N2 effect of the go/no-go task was enhanced after training for girls. This study is the first to show that pure response inhibition training can potentially improve reasoning ability. Furthermore, gender differences in the training-induced changes in neural activity were found in preschoolers.

Results of prev ious studies of the relationship between prosocial behav ior and intelligence hav e been inconsistent. This study attempts to distinguish the dif f erences between sev eral prosocial tasks, and explores the way s in which cognitiv e ability inf luences prosocial behav ior. In Study One and Two, we reexamined the relationship between prosocial behav ior and intelligence by employ ing a costly signaling theory with f our games. The results rev ealed that the prosocial lev el of smarter children is higher than that of other children in more complicated tasks but not so in simple tasks. In Study Three, we tested the moderation ef f ect of the av erage intelligence across classes, and the results did not show any group intelligence ef f ect on the relationship between intelligence and prosocial behav ior.

The objective of this study was to investigate the impact of trauma exposure on the posttraumatic stress symptomatology (PTSS) of children who resided near the epicenter of the 2008 Wenchuan earthquake. The mechanisms of this impact were explored via structural equation models with self-esteem and coping strategies included as mediators. The findings suggested that the effect of trauma exposure was partially mediated by self-esteem, which subsequently affected coping strategies and finally determined PTSS. These results imply that self-esteem and coping strategies may impact children's resilience to trauma exposure.

We examined relationships between ethical leadership and leaders' personality dimensions using the Ethical Leadership Scale (Brown, Trevino, & Harrison, 2005) and the NEO Five-Factor Inventory: Form S (Costa & McCrae, 1996; McCrae & Costa, 1987). We obtained data from subordinate-supervisor dyads from 59 community healthcare centers located in a city in northern China. Results of regression analysis revealed that neuroticism was negatively (beta = -.29, p < .05), and extraversion (beta = .27, p < .05), agreeableness (beta = .40, p < .01), and conscientiousness (beta = .40, p < .01) positively, related to ethical leadership, when leaders' demographics were controlled for. Implications for future investigations of ethical leadership and for management practice are discussed.

A cued Go-Nogo task was employed to explore the neural correlation among response preparation, cognitive control and intelligence in two groups of early adolescents with different intellectual levels using event-related potential (ERP) technique. Behavioral results indicated that the gifted children had better cognitive control performances with higher correct hit rate and lower commission error rate than the average children. Electrophysiological results further showed that the gifted children elicited efficient cue-P2 response for automatic cue detection and stronger cue-P3 activation for cue evaluation. Moreover, gifted children induced faster N2 and Nogo-P3 responses for conflict monitoring and inhibition processing and stronger P3 activation for attentional control. The current results supported the neural efficiency hypothesis of intelligence and further shed light on the close relationship among response preparation, cognitive control and human intelligence.

The present study had two aims: First, to investigate the joint and specific roles of working memory (WM) and intelligence as predictors of school achievement. And second, to replicate and extend earlier findings (Spinath, Spinath, Harlaar, & Plomin, 2006) on the incremental validity of non-cognitive over cognitive abilities in the prediction of school achievement. The present sample consisted of N = 179 Chinese primary school children in the fourth grade. All measures including working memory (WM), intelligence and motivational items were assessed in class. Teachers provided test scores for the domains of Chinese and Math. We found that WM was a good predictor of school achievement and comparable in predictive power to intelligence. Together, cognitive ability including both WM and intelligence explained 17.8% and 36.4% of the variance in children's Chinese and Math scores, respectively. The relative importance of WM and intelligence varied with school domains with greater predictive power of WM for Math while intelligence explained a greater proportion of the variance in Chinese although the magnitude of this difference was only moderate. Domain-specific motivational constructs contributed only marginally to the prediction of school achievement for both Chinese and Math. Crown Copyright (C) 2011 Published by Elsevier Inc.

Accumulating evidence suggests that inhibitory ability is related to intelligence, while other studies don’t confirm this finding. This study explored the relationship of intelligence to inhibitory control in primary school children, aged 7- to 8-year-old, 9- to 10-year-old and 11- to 12-year-old. Raven's advanced progressive matrices and Cattell's Culture Fair Test were administered. The inhibitory ability was measured with a computerized Stroop Test. There was only significant correlation between intelligence and Stroop Test on 11- to 12-year-old children. These results suggested that the relationship between intelligence and inhibitory control was dependent on the participants’ age. © 2009 Published by Elsevier Ltd.

In diesem Beitrag werden zwei Untersuchungen zur diagnostischen Kompetenz von Lehrkräften und den motivational-affektiven Merkmalen unterschätzter und überschätzter Schüler präsentiert. An den Untersuchungen in Deutschland und China nahmen jeweils acht Grundschulklassen sowie deren Mathematiklehrer teil. Die Viertklässler bearbeiteten einen Mathematikleistungstest und einen Selbstbeschreibungsfragebogen. Die Lehrkräfte schätzten die Schüler in Bezug auf die Testleistung und motivational-affektive Merkmale ein. Auf Grundlage der geschätzten und der tatsächlichen Testleistung erfolgte eine Einteilung in unterschätzte und überschätzte Schüler. Beide Untersuchungen kommen zu übereinstimmenden Ergebnissen. Die Lehrkräfte konnten Testleistungen mit guter Genauigkeit prognostizieren, aber hatten Schwierigkeiten damit motivational-affektive Schülermerkmale richtig einzuschätzen. Unterschätzte Schüler zeigten die gleiche Testleistung und Lernmotivation wie überschätzte Schüler, aber hatten eine niedrigere Erfolgserwartung, ein niedrigeres Fähigkeitsselbstkonzept und eine höhere Leistungsangst. Die Lehrer erwarteten, dass unterschätzte Schüler in der nächsten Mathematikarbeit schlechter abschneiden werden und mit schlechteren Noten zufrieden sind als überschätzte Schüler. Der Beurteilungsfehler der Lehrer beschränkte sich nicht allein auf die Testleistung, sondern generalisierte auf motivational-affektive Schülermerkmale.

The personality predictors of posttraumatic stress disorder in orphan survivors after the 2008 Sichuan earthquake in China were investigated. Half a year after the earthquake, 196 preearthquake and 116 postearthquake orphans who survived were recruited. All participants completed the Eysenck Personality Questionnaire for Children (Gong, 1984) and Children's Revised Impact of Event Scale (Smith, Perrin, Dyregrov, & Yule, 2003). The regression analysis showed that the Neuroticism score was the strongest predictor of the severity of PTSD symptoms for both pre- and postearthquake orphans. For the preearthquake orphans, the Extraversion trait predicted Arousal negatively, and the Lie trait predicted Intrusion and Arousal positively. However, for the postearthquake orphans, only the Extraversion trait predicted Avoidance positively.
