Sophistication about Self-Control

We propose a broadly applicable empirical approach to classify individuals as time-consistent versus naive or sophisticated regarding their self-control limitations. Operationalizing our approach based on nationally representative data reveals that self-control problems are pervasive and that most people are at least partly aware of their limited self-control. Compared to naifs, sophisticates have higher IQs, better educated parents, and are more likely to take up commitment devices. Accounting for both the level and awareness of self-control limitations has predictive power beyond one-dimensional notions of self-control that neglect awareness. Importantly, sophistication fully compensates for self-control problems when choices involve immediate costs and later benefits. Raising people's awareness of their own self-control limitations may thus assist them in overcoming any adverse consequences.

Improvement of group climate in a residential setting for juveniles with mild intellectual disability through training of staff in Non-Violent Resistance.

An open group climate is essential in successful residential care for juveniles with mild intellectual disability (MID). This study examined whether non-violent resistance, adapted for MID (NVR-MID), stimulates an open group climate in time. NVR-MID was implemented in three residential settings in The Netherlands, in a quasi-experimental stepped wedge design. In total, 124 clients with MID (Mage = 16.39 [SD=4.95], 49.9% male) participated. Group climate was assessed seven times with the Group Climate Inventory for Children or the Group Climate Inventory-Revisited (GCI-R), during a total of 20 months. Open group climate scores increased in all three institutions; effect size was medium. Clients with lower IQs experienced group climate as more positive compared to clients with higher IQs. Effects were similar for both groups. As NVR-MID appeared to contribute to a positive experienced group climate, it might be advisable to implement NVR-MID on larger scale.

Examining the Relationships among Cognitive Ability, Domain-Specific Self-Concept, and Behavioral Self-Esteem of Gifted Children Aged 5-6 Years: A Cross-Sectional Study.

Although childhood is a critical period of development during which all children begin a lifelong process of self-discovery that shapes their identities, few studies have focused on the self-concept and self-esteem of young, gifted children. This study recruited 108 gifted children aged 5–6 years from Greece and their preschool teachers to explore the relationships among cognitive ability, domain-specific self-concepts, and global self-esteem. The Pictorial Scale for Perceived Competence and Social Acceptance was used to assess the domain-specific self-concepts of the participants, whereas behavioral manifestations of self-esteem were rated by the children’s teachers using the Behavioral Academic Self-Esteem Scale. There were positive correlations among IQ, perceived scholastic competence, and global self-esteem. Hierarchical regression analysis indicated that significant predictors of global self-esteem were male gender, higher IQ, perceived scholastic competence, and perceived maternal acceptance. Additionally, there were gender differences in global self-esteem and perceived physical competence in favor of boys, whereas perceived maternal acceptance favored girls. This article discusses the need for practitioners working with gifted children to enact a comprehensive social–emotional learning curriculum in schools that promotes academic as well as personal and character strengths. Finally, the limitations of the study and suggestions for future research are also presented.

Breakfast Consumption Habits at Age 6 and Cognitive Ability at Age 12: A Longitudinal Cohort Study.

This study aimed to assess the relationship between breakfast composition and long-term regular breakfast consumption and cognitive function. Participants included 835 children from the China Jintan Cohort Study for the cross-sectional study and 511 children for the longitudinal study. Breakfast consumption was assessed at ages 6 and 12 through parental and self-administered questionnaires. Cognitive ability was measured as a composition of IQ at age 6 and 12 and academic achievement at age 12, which were assessed by the Chinese versions of the Wechsler Intelligence Scales and standardized school reports, respectively. Multivariable general linear and mixed models were used to evaluate the relationships between breakfast consumption, breakfast composition and cognitive performance. In the longitudinal analyses, 94.7% of participants consumed breakfast ≥ 4 days per week. Controlling for nine covariates, multivariate mixed models reported that compared to infrequent breakfast consumption, regular breakfast intake was associated with an increase of 5.54 points for verbal and 4.35 points for full IQ scores (p < 0.05). In our cross-sectional analyses at age 12, consuming grain/rice or meat/egg 6–7 days per week was significantly associated with higher verbal, performance, and full-scale IQs, by 3.56, 3.69, and 4.56 points, respectively (p < 0.05), compared with consuming grain/rice 0–2 days per week. Regular meat/egg consumption appeared to facilitate academic achievement (mean difference = 0.232, p = 0.043). No association was found between fruit/vegetable and dairy consumption and cognitive ability. In this 6-year longitudinal study, regular breakfast habits are associated with higher IQ. Frequent grain/rice and meat/egg consumption during breakfast may be linked with improved cognitive function in youth.

INTELLIGENCE'S EFFECTS ON SECOND LANGUAGE LEARNING

It is often assumed that intellect is the most important element in determining whether or not a person would be successful in learning a second language. When compared to someone with a moderate IQ, someone with a high IQ learns a second language faster. However, this is not always the case. In my perspective, not every person with a high IQ finds it difficult to learn a second language. Other research discovered other factors that influence someone's performance in learning a second language. This demonstrates how various things impact someone's decision to learn a second language. The most significant variables in learning a second language are social variables. As a result, if they have medium intellect, learning a second language is not an issue. If they acquire a second language in a supportive atmosphere, they will be able to master the second language. As a result, selecting a decent social context in which to learn a second language is the most efficient approach to master it.

Examining Phenotypical Heterogeneity in Language Abilities in Chinese-Speaking Children with Autism: A Naturalistic Sampling Approach.

Phenotypical heterogeneity in language abilities is a hallmark of autism but remains poorly understood. The present study collected naturalistic language samples from parent-child interactions. We quantified verbal abilities (mean length of utterance, tokens, types) of 50 Chinese-speaking children (M = 5; 6) and stratified subgroups based on their autism traits, IQ, and language abilities. Using hierarchical cluster analysis, four groups were identified. Group 1, the least affected group, had mild autism, the highest IQ, and the strongest verbal abilities. Group 2, the severely affected group, had the lowest IQ, most severe autism symptoms, and weakest verbal abilities. Group 3 and Group 4 displayed average levels of verbal abilities and IQ. These findings may characterize the heterogeneous profiles of verbal abilities in Chinese-speaking children.

An exploration of the genetic epidemiology of non-suicidal self-harm and suicide attempt

BackgroundEmpirical evidence supporting the distinction between suicide attempt (SA) and non-suicidal self-harm (NSSH) is lacking. Although NSSH is a risk factor for SA, we do not currently know whether these behaviours lie on a continuum of severity, or whether they are discrete outcomes with different aetiologies. We conducted this exploratory genetic epidemiology study to investigate this issue further.MethodsWe explored the extent of genetic overlap between NSSH and SA in a large, richly-phenotyped cohort (the Avon Longitudinal Study of Parents and Children; N = 4959), utilising individual-level genetic and phenotypic data to conduct analyses of genome-wide complex traits and polygenic risk scores (PRS).ResultsThe single nucleotide polymorphism heritability of NSSH was estimated to be 13% (SE 0.07) and that of SA to be 0% (SE 0.07). Of the traits investigated, NSSH was most strongly correlated with higher IQ (rG = 0.31, SE = 0.22), there was little evidence of high genetic correlation between NSSH and SA (rG = − 0.1, SE = 0.54), likely due to the low heritability estimate for SA. The PRS for depression differentiated between those with NSSH and SA in multinomial regression. The optimal PRS prediction model for SA (Nagelkerke R2 0.022, p < 0.001) included ADHD, depression, income, anorexia and neuroticism and explained more variance than the optimal prediction model for NSSH (Nagelkerke R2 0.010, p < 0.001) which included ADHD, alcohol consumption, autism spectrum conditions, depression, IQ, neuroticism and suicide attempt.ConclusionsOur findings suggest that SA does not have a large genetic component, and that although NSSH and SA are not discrete outcomes there appears to be little genetic overlap between the two. The relatively small sample size and resulting low heritability estimate for SA was a limitation of the study. Combined with low heritability estimates, this implies that family or population structures in SA GWASs may contribute to signals detected.

Critical Thinking: A Model of Intelligence for Solving Real-World Problems.

Most theories of intelligence do not directly address the question of whether people with high intelligence can successfully solve real world problems. A high IQ is correlated with many important outcomes (e.g., academic prominence, reduced crime), but it does not protect against cognitive biases, partisan thinking, reactance, or confirmation bias, among others. There are several newer theories that directly address the question about solving real-world problems. Prominent among them is Sternberg’s adaptive intelligence with “adaptation to the environment” as the central premise, a construct that does not exist on standardized IQ tests. Similarly, some scholars argue that standardized tests of intelligence are not measures of rational thought—the sort of skill/ability that would be needed to address complex real-world problems. Other investigators advocate for critical thinking as a model of intelligence specifically designed for addressing real-world problems. Yes, intelligence (i.e., critical thinking) can be enhanced and used for solving a real-world problem such as COVID-19, which we use as an example of contemporary problems that need a new approach.

Limited Internal Comparability of General Intelligence Composites: Impact on External Validity, Possible Predictors, and Practical Remedies.

Research on comparability of general intelligence composites (GICs) is scarce and has focused exclusively on comparing GICs from different test batteries, revealing limited individual-level comparability. We add to these findings, investigating the group- and individual-level comparability of different GICs within test batteries (i.e., internal score comparability), thereby minimizing transient error and ruling out between-battery variance completely. We (a) determined the magnitude of intraindividual IQ differences, (b) investigated their impact on external validity, (c) explored possible predictors for these differences, and (d) examined ways to deal with incomparability. Results are based on the standardization samples of three intelligence test batteries, spanning from early childhood to late adulthood. Despite high group-level comparability, individual-level comparability was often unsatisfactory, especially toward the tails of the IQ distribution. This limited comparability has consequences for external validity, as GICs were differentially related to and often less predictive for school grades for individuals with high IQ differences. Of several predictors, only IQ level and age were systematically related to comparability. Consequently, findings challenge the use of overall internal consistencies for confidence intervals and suggest using confidence intervals based on test–retest reliabilities or age- and IQ-specific internal consistencies for clinical interpretation. Implications for test construction and application are discussed.

Investigation of clinical features of dysgraphia related to the subtypes of developmental coordination disorder in children regarding high IQ

IntroductionHandwriting disorder is commonly observed in Developmental Coordination Disorder (DCD) (87-88%) and is often noted in children with high Intellectual Quotient (HIQ).Two mainly pure DCD subtypes: ideomotor-DCD (IM), visuospatial/or visuoconstructional-DCD (VSC) and a mixed subtype (MX) were identified in the literature but nothing is known regarding IQ and dysgraphia.ObjectivesTo refine the specific clinical features of dysgraphia related to DCD subtypes regarding IQ levels.Methods Neurovisual, neuropsychological, neuropsychomotor functions, and handwriting performances of 38 children (6-to-12 years-old: mean 9y, SD 2.7) diagnosed with DCD (DSM-5 criteria) were collected. Two matched groups were analyzed according to their IQ: 19 (TC) typical children (IQ=90-110) and 19 HIQ children (IQ&gt; 120).Results IQ scores were not significantly associated with dysgraphia. There isa significant difference between TC vs HIQ with a lower rate of IM-DCD respectively 11% vs 5% (p=.035) and 68% vs 37% for VSC-DCD (p=.03) but 21% vs 58% in MX-DCD (p=.41). Dysgraphia was significantly more present in TC group with MX-DCD and in HIQ with VSC-DCD. A negative correlation between Kho’s’ cubes test failure (p=.006), visual-spatial memory (p=.05) and VSC-DCD was noted in HIQ group. The deficit of visual spatial memory was significantly related to dysgraphia in HIQ children (p=.01) associated to visual gnosis impairment (p=.03).ConclusionsDysgraphia was significantly found with VSC-DCD subgroup in FIQ&gt;120 with specific features of visual perception disorders suggesting more involvement of the right cortex. These results suggest that VSC-DCD in HIQ could be a neurovisual impairment rather than a pure VSC-DCD.

Special Educational Need of the Gifted and Talented Students in Saudi Arabia: A Review Paper

Giftedness refers to proficient distinctive intelligent knowledgeable abilities, due to high IQ which possess talent, excellent performance abilities and skill in diverse field of learning. The gifted children’s style of learning is quite different as they need special academic, scientific support and input since they are characterized by actively metacognitive thinking skills and learning strategies. Due to the complexities of twice-exceptional gifted students, educators lack the experience in dealing with the unique needs of the gifted students. In Saudi Arabia, there is a need for the government to restructures the educational system in order to refine gifted student’s talent to their educational needs. This is a review paper aims at reviewing relevant literature on the special educational needs of the gifted and talented students in Saudi Arabia. From the available literature reviewed, the general need for gifted and talented students identified are cognitive needs, social and emotional needs, psychomotor needs, affective and intuitive needs, the needs of diverse gifted populations. The Study also identified the four major special educational needs of the gifted and talented students which comprises; the need for challenging education, need for true peers, the need for the responsive parenting, the need for adult empathy.

Prognostic factors and predictors of outcome in children with autism spectrum disorder: the role of the paediatrician

BackgroundAutism spectrum disorder is a complex condition with wide variation in type and severity that involves persistent challenges in social interaction, speech and nonverbal communication, restricted/repetitive behaviours and adaptive behaviours. In recent years, research has deepened the study of the predictive factors of optimal outcome, intended as indicators of positive trajectory in children with a previous diagnosis of autism who, after a therapeutic path, show a significant reduction in the “core” symptoms of autism and a positive evolution in social, adaptive, affective, and relational skills.MethodsThe study included 40 children aged 21 to 66 months, enrolled between 2015 and 2016 for an autism spectrum disorder clinical suspicious. Children were re-evaluated after at least 2 years of therapy and they were divided into two groups: the ASD-ASD group included children with a confirmed diagnosis of ASD, and the ASD-OO comparison group included children who no longer met the criteria for an autism classification. The aim of this retrospective study was to investigate the presence of cognitive, emotional and relational predictors capable of predicting the presence of optimal outcome in with a diagnosis of autism; the predictors taken into consideration were the intelligence quotient, the play, the emotional contagion and the understanding of other’s intentions. In this way, it is possible to support clinicians in defining a more complete diagnostic framework of autism, using assessment tools that can be administered quickly and therefore suitable for short observation sessions in paediatric patients.ResultsThe findings showed that 15 out of 40 children, after at least for 2 years, no longer fell into the diagnostic ASD category based on the ADOS-2, DSM-5 and clinical criteria. The children in the ASD-OO group initially had a higher IQ than those in the ASD-ASD group, lower severity of autistic symptoms, greater understanding of intentions, more emotional contagion, and better quality of play. The results suggest that the initial coexistence of skills in these areas at the time of the first diagnostic assessment may allow us to predict the possibility of achieving optimal outcome after 2 years of therapy.ConclusionsThe data of this study highlight the importance of considering, during assessment, intelligence quotient, play, emotional contagion, and understanding of the intentions of others as potential prognostic predictors that can become useful tools for clinicians and paediatricians. This allows us to focus attention, in both the diagnostic and prognostic phases, on emotional-relational variables that can support the clinician in defining a more complete diagnostic framework and in planning a more personalized therapeutic path.

Review of Cognitive Characteristics of Autism Spectrum Disorder Using Performance on Six Subtests on Four Versions of the Wechsler Intelligence Scale for Children

This study was a systematic review of research using the Wechsler Intelligence Scale for Children (WISC) with Autism Spectrum Disorder (ASD) to examine cognitive characteristics of children with ASD beyond the impact of revisions based on WISC and diagnostic criteria changes. The classic “islets of ability” was found in individuals with full-scale IQs < 100. The “right-descending profiles” were observed among high IQ score individuals. High levels on the Block Design and low Coding levels were consistently found regardless of the variation in intellectual functioning or diagnosis. This review identified patterns of cognitive characteristics in ASD individuals using empirical data that researchers may have previously been aware of, based on their experiences, owing to the increased prevalence of ASD.

Daily living skills in adolescents with autism spectrum disorder: Implications for intervention and independence

BackgroundChallenges in adaptive behaviors are present in individuals with autism spectrum disorder (ASD), while variation in IQ, social skills, and comorbidities are possible influences on adaptive behaviors. However, adaptive behaviors do not consistently map onto cognitive abilities in ASD, as high IQ is not protective against challenges in adaptive behaviors. Additionally, individuals with both ASD and elevated levels of externalizing problem behaviors experience even worse adaptive behaviors. Identifying factors that contribute to the variance in adaptive behaviors, particularly daily living skills (DLS), may inform strategies to improve adaptive behaviors necessary for independence in adulthood. MethodAdolescents with typical cognitive development (TD, n = 84), intellectual disability (ID, n = 30), or ASD (n = 45) were included in this study to examine group differences in adaptive behaviors, identify relations between IQ and DLS, and determine factors that contribute to variance in DLS at youth age 13. The Vineland Adaptive Behavior Scales, 2nd Edition (VABS-II) was used to measure adaptive behaviors. ResultsAll domains of adaptive behavior were significantly higher in TD groups compared to ASD and ID youth. Significant positive correlations were observed between IQ and DLS in the ASD and ID groups. In the ASD youth group, higher externalizing behavior problems explained the most variance in DLS. ConclusionsDLS are below age-expected levels in young adolescents with ASD, in part because of the higher externalizing behavior problems in this group. Incorporating adaptive skills training and behavior management strategies into current interventions may serve to prepare adolescents and families for the transition to adulthood.

Anime affection on human IQ and behavior in Saudi Arabia

The present study attempted to determine the effects of watching anime and understanding if watching anime could affect the mental and social aspects of kids or other group of ages, and also to decide that the teenagers and children should watch anime or not. The research design used in this study is the descriptive research method and observational where in data and facts from direct observations and online questionnaires were used to answer the research question. The finding of this study suggested that anime viewers has higher level of general knowledge comparing with the non- anime viewers and as well as higher IQ level significantly in a specific group, besides anime can be used to spread a background about any culture and plays a role in increase the economy.

A Retrospective Study of Demographic, Medical, and Psychological Predictors of Readiness in Service Members With Mild Traumatic Brain Injury

Given the significant number of service members who have incurred mild traumatic brain injury (TBI) over the past two decades, this study was completed to determine the relative contribution of demographic, TBI-related, and psychological factors that predict the readiness of service members with primarily mild TBI. This retrospective study included 141 service members who were evaluated at an outpatient military TBI rehabilitation clinic. Information regarding demographics, TBI-related variables, and psychological factors was collected and entered into hierarchical multinomial logistic regressions to predict military work status. Demographic predictor variables included age, race, gender, rank, service branch; TBI-specific variables including time since injury and neuropsychological variables (i.e., Wechsler Adult Intelligence Scale-IV (WAIS-IV) Full Scale Intelligence Quotient (FSIQ) and Processing Speed Indices; California Verbal Learning Test-IV total recall t-score); and psychiatric variables including concomitant psychiatric diagnoses and Personality Assessment Inventory indices. The outcome variable was the service member's military work status (i.e., return to duty (RTD); Medical Evaluation Board-disabled (MEB); retired) at time of discharge from the TBI clinic. Statistical analyses indicated that the total model predicted 31% of the variance in work status, with demographics predicting 16% of the variance, concomitant psychiatric diagnoses and WAIS-IV FSIQ predicting an additional 12%, and subjective somatic/psychological distress (Personality Assessment Inventory indices) predicting an additional 3%. Regarding the primary groups of interest (i.e., RTD vs. MEB), stepwise regressions indicated that those who RTD have higher intelligence and report less physical/psychological distress than the disabled group. In general, those service members who were able to RTD versus those who were classified as disabled (MEB) were of higher IQ and reported less somatic/psychological distress. Of note, traditional indices of TBI severity did not predict the ability of the sample to RTD. The results suggest the importance of treating psychological conditions and identifying possible indicators of resilience (e.g., higher intelligence) to increase the readiness of service members with mild TBI.

How can wellbeing at work and sustainable employability of gifted workers be enhanced? A qualitative study from a capability approach perspective

BackgroundBeing gifted with a very high IQ (> 98 percentile) can provide an advantage in the occupational context but can also come with its` own specific challenges. Where some studies found higher than average levels of wellbeing at work and successful careers amongst the gifted, other studies report boredom and less job satisfaction. This poses the question what gifted people value in work, and which factors are associated with the achievement of valued work related outcomes, wellbeing and sustainable employability. In this study these questions were explored using the value driven capability approach as a theoretical framework.MethodA qualitative approach was chosen and 16 in-depth semi-structured interviews with gifted workers (IQ > 130) were conducted. The transcripts were analysed using a reflexive thematic analysis aimed at identifying the work related outcomes participants aspired to achieve and the contextual and personal factors that affected the actualisation of these outcomes.ResultsParticipants placed great value on the opportunity to learn, to use their knowledge and skills, and tended to have high ethical standards. If realized, these values contributed to wellbeing whereas if not fulfilled, this often resulted in frustration and sadness. The most important personal factors associated with wellbeing at work and sustainable employability were the level of organizational awareness, self-knowledge, a willingness to compromise, and fear of stigmatisation. Contextually a facilitating leadership style of managers was important, allowing the worker autonomy and decision latitude. Socially, participants enjoyed others as sparring partners but often had an aversion to small talk which could lead to social avoidance and loneliness.ConclusionsIf gifted workers managed (to get) what they valued in work, this was associated with wellbeing and sustainable employment Coaching aimed at improving organizational awareness, specific social skills (e.g. small talk, adaptability) and understanding their own cognitive processes could be valuable. The application of an autonomy supporting facilitative leadership style by supervisors would be beneficial. Further research should try to confirm the findings using quantitative methods and needs to examine more closely the impact of stigmatisation and leadership styles.

The Nuanced Relationship Between Creative Cognition and the Interaction Between Executive Functioning and Intelligence

AbstractThe current study addresses gaps in our understanding of the relationship between creative cognition, intelligence (IQ), and executive functioning (EF). Undergraduate students completed an IQ test, verbal and figural divergent thinking (DT) tests, and a self‐assessment of EF, across four study sessions. Participant data (N = 199) were analyzed using linear regression and PROCESS moderation models. Results demonstrated that EF interacts with IQ to predict figural and verbal DT in distinct ways, with different patterns emerging from different methods of scoring DT. Using traditional DT scoring, Gf (but not Gc) significantly moderated the relationship between EF and scores on both verbal and figural DT tasks. Low EF was associated with diminished DT scores for those with low Gf scores, unrelated for those with relatively higher Gf, and enhanced scores for those with the highest Gf. Using originality ratio scores, low EF was associated with diminished originality in verbal DT responses for those with low IQ (both Gf and Gc), unrelated for those with relatively higher IQ, and enhanced originality for those with the highest Gc (but not Gf) scores. Thus, there are several nuances in the way that EF interacts with IQ to predict DT.

Relationship between IQ and academic performance of medical students.

Objective: The objectives of this study were to find the correlation among the intelligence and academic achievement of MBBS students and to see if the correlation differs between boys and girls. Study Design: Cross Sectional Study. Setting: Ameer Ud Din Medical College / PGMI Lahore. Period: 1st January 2019 to 31st January 2019 Material &amp; Methods: A total of 100 second year MBBS students volunteered to participate (46 males and 54 females). Modified Wechsler Adult Intelligence Scale (WAIS) was used to access the IQ of students. Previous academic records of the students before their admission in medical college and written and oral test marks of second year MBBS students during the year were used for measuring academic achievements of students. The results were analyzed by spearmans correlation, Independent t test and Mann Whitney U test. Results: A statistically significant difference (p = 0.04) between IQ of boys and girls was found with males having mean IQ of 97.4±22.7 as compared to females 89.3±15.5. No significant difference was observed in academic achievements of male and female students. Correlation of IQ with academic achievements was also non-significant. Conclusion: Although males have higher IQ but it has no relationship with academic achievement of medical students. Hard work of the students with average or low IQ could be the reason that there was no difference in the academic achievement when they were compared with the students having higher IQ.
