Which is the real intelligence? A reply to Robinson (1999)

Robinson's ([Robinson, D.L. (1999). The ‘IQ’ factor: implications for intelligence theory and measurement. Personality and Individual Differences, 27, 715–735]) arguments that crystallized intelligence represents the “one valid intelligence factor” are disputed. It is argued that Robinson seriously underestimated the relevance of fluid abilities to “intelligence”, by using an inappropriate criterion for assessing the intelligence-saturation of cognitive ability variables. The relevance of fluid and crystallized abilities to popular, psychometric, and biological conceptions of intelligence is discussed, and the issue of age-related changes in fluid and crystallized intelligence is also addressed.     

Cognitive abilities of street children: Low-SES Bolivian boys with and without experience of living in the street

Objectives: This study compared results on cognitive tests measuring nonverbal visualization and reasoning, executive functions, and creativity between 36 boys with experience of living in the street and 31 housed yet socioeconomically equivalent boys, in Bolivia.

Results: The street children scored significantly higher on the creativity measure, which is discussed in relation to contextual relevance. No significant differences were found on the other cognitive tests. Time elapsed after living in the street and drug use were strongly associated with cognition, while age was not. Both groups scored below average compared to Western norms. The results are discussed in terms of the cultural relevance of the tests and the impact of socioeconomic status, stress, and stimulation on cognition.     

Differential ability antecedents of general and specific dimensions of declarative knowledge: More than g

The purpose of the current study is to test the proposition that the relative contribution of narrow abilities (but not of g) may have been obscured in prior research due to a failure to employ fully multidimensional latent variable analyses. The current study corrects for these deficiencies and examines the relationships between cognitive abilities and domain-specific declarative knowledge. Results show that when observed criterion test scores were individually regressed on abilities, only g was consistently related to the criteria. However, when a latent variable analysis was applied to the same data, both g and narrow ability factors accounted for substantial portions of variance in different latent criterion constructs. Implications are discussed.     

认知能力对学业成绩的影响:有中介的调节模型

学业成绩是衡量学生掌握知识水平的重要指标,受到认知能力、社会支持和学习动机等多重因素的显著影响,而这多重因素间的关系及其对学业成绩的共同作用机制尚不明确。本研究采用标准化的认知能力测验、社会支持量表、学习动机量表对4,973名初中生进行测试,并以各科测验成绩总分的平均值作为学业成绩指标。结果表明：（1）认知能力、社会支持、学习动机均与学业成绩正相关;（2）社会支持在认知能力对学业成绩的影响中起调节作用,学生感受到的社会支持水平越高,学业成绩表现越好,且其认知能力对学业成绩的预测作用越强;（3）社会支持的调节作用部分通过学习动机这一中介变量实现。本研究构建了一个基于个体因素（认知能力和学习动机）和环境因素（社会支持）共同影响学业成绩的理论模型,有利于人们深入理解认知能力影响学业成绩的内在机制和边界条件,为提升学生学业成绩提供了理论依据和实证支持。     

Social cognitive predictors of college students’ academic performance and persistence: A meta-analytic path analysis

This study tested Social Cognitive Career Theory’s (SCCT) academic performance model using a two-stage approach that combined meta-analytic and structural equation modeling methodologies. Unbiased correlations obtained from a previously published meta-analysis [Robbins, S. B., Lauver, K., Le, H., Davis, D., & Langley, R. (2004). Do psychosocial and study skill factors predict college outcomes? A meta-analysis. Psychological Bulletin, 130, 261–288.] were used to create the input correlation matrices for subsequent path-analytic tests of the model, using both college GPA and retention as performance criteria. Results suggested that SCCT does an adequate to excellent job of modeling academic performance and persistence, but that model fit was better when general cognitive ability versus high school GPA was used to operationalize the ability/past performance variable. Results are discussed in terms of their fit with SCCT and their practical implications.

L’apport des tests d’aptitudes dans le recrutement : l’exemple de la NV5-R

From the observation of a limited use of aptitude tests in the recruitment process, this article attempts to illustrate the relevance of such tests from applied research on the recruitment of sales persons. Thus, 32 candidates have participated in the recruitment process that is traditionally practiced by the organization, to which we have added three of the subtests of the battery NV5-R. The comparison of the scores at this test and the results of the classical procedure of recruitment for each subject shows that similar information is obtained by these two methods of selection. The contribution of aptitude tests in selection procedures has been discussed in terms of these results while laying the limitations of this study.     

Passive smoking is associated with cognitive and emotional impairment in adolescent girls

It is well established that smoking is associated with impaired mental health and sleep problems. However, the possible effects of passive smoking on cognitive and emotional characteristics have not previously been evaluated in adolescents. We investigated the association between passive smoking and cognitive and emotional function, and sleep patterns in 940 adolescent girls. The girls were divided into two groups [305 exposed subjects and 635 non-exposed subjects (the controls)]. The passive smokers had a significantly lower cognitive function and higher depression, aggression, and insomnia scores compared to the control group (P?<?0.05). No significant difference was detected with respect to day-time sleepiness and sleep apnea. Logistic regression analyses showed that the passive smokers were more likely than the controls to have cognitive impairments, depressive mood, aggressive behavior, and insomnia. Adolescent passive smokers had significant differences in their cognitive abilities and emotional function.     

Cognitive competencies and aggressive behavior: A developmental study

A number of studies have demonstrated that increased socially related cognitive skills are associated with decreases in aggressive behavior. However, the link between aggression and intelligence or academic skills is less evident. While some research indicates that poor academic performance is related to aggression, it is unclear which components of intellectual ability and performance are critical to the management of aggressive behaviors. In two independent longitudinal studies of elementary school-age children, the relationship among several aspects of cognitive competence and several aspects of aggressive behavior were examined. The results of the first study showed that aggressive behavior observed in kindergarten children was more closely related to academic performance in the first and second grades than to general cognitive ability (IQ). The results of the second study, a comprehensive three-year investigation of upper elementary school-age children, indicated that teachers' assessments of aggression and parents' ratings of cruelty were consistent over time for boys, but not for girls. The intercorrelations among aggression measures within each of the three years also revealed stable sex differences. Boys identified as aggressive in the classroom were more likely to be perceived as aggressive, cruel, and/or delinquent at home, but for girls, there was little correlation between aggression at school and in the home. The analyses relating measures of cognitive functioning to indices of aggressive behavior made clear the importance of discriminating among various facets of these psychological constructs. IQ had a negligible relationship with aggression and a weak inverse relationship to delinquency. An overall index of cognitive functioning was a somewhat more consistent negative correlate of aggression, cruelty, and delinquency, especially for boys. A similar pattern was found for the correlates of academic performance. Academic disability was strongly related to delinquency in boys, and to a lesser degree to aggression in boys. Of the several cognitively related factors that were explored, Low Need Achievement manifested the strongest and most consistent relationships with the different facets of aggression and antisocial behavior, especially in boys. The implications of these results for psychological interventions in the school are discussed.     

Does learning behavior augment cognitive ability as an indicator of academic achievement?

Measures of cognitive ability have a rich history of accounting for meaningful levels of achievement variance. In contrast to other student characteristics, however, they are somewhat limited in terms of their intervention relevance and treatment validity. Alternatively, children's observable learning behaviors are believed to enhance both treatment validity and the predictions afforded by cognitive ability. This study examined student learning behaviors in the context of cognitive ability and academic achievement. Three structural models were evaluated on a sample of 1304 students ranging in age from 6 to 17 years. Results supported the unique relationship between learning behavior and academic achievement, beyond cognitive ability. Multi-group structural equation modeling (SEM) analysis revealed that these findings were invariant across groups differing by gender and ethnicity. These findings are consistent with previous observations that children's behavioral features in learning situations will supplement the outcome-oriented standardized tests of cognitive ability.     

Effects of age and ability on components of cognitive change

Prior experience with a cognitive task is often associated with higher performance on a second assessment, and these experience effects can complicate the interpretation of cognitive change. The current study was designed to investigate experience effects by obtaining measures of cognitive performance separated by days and by years. The analyses were based on data from 2017 adults with two longitudinal occasions, of whom 948 had also completed a third occasion, with each occasion consisting of three parallel versions of the tests on separate sessions. Change across short intervals was typically positive, and greater among older adults and adults with low levels of cognitive ability, whereas change over intervals of approximately three years was often negative, particularly at older ages. In contrast to the expectation that change over short intervals might be informative about change over longer intervals, relations between short-term change and long-term change were negative, as the individuals who gained the most with assessments separated by days tended to experience the greatest losses across assessments separated by years.     

Scholastic Attainment Following Severe Early Institutional Deprivation: A Study of Children Adopted from Romania

The relationship between severe early institutional deprivation and scholastic attainment at age 11 in 127 children (68 girls and 59 boys) adopted from institutions in Romania was compared to the attainment of 49 children (17 girls and 32 boys) adopted within the UK from a non-institutional background. Overall, children adopted from Romania had significantly lower attainment scores than those adopted within the UK; the children within the Romanian sample who had spent 6 months or more in an institution had significantly lower attainment scores than those who had spent less than 6 months in an institution, but there was no additional risk of low attainment associated with longer institutional care after 6 months. The lower scholastic attainment in the children adopted from Romanian institutions, as compared with domestic adoptees, was mediated by IQ, and to a lesser degree, inattention/overactivity. When these factors were taken into account, only small between-group differences in attainment remained.     

Probing the limits of tool competence: Experiments with two non-tool-using species (Cercopithecus aethiops and Saguinus oedipus)

Non-human animals vary in their ability to make and use tools. The goal of the present study was to further explore what, if anything, differs between tool-users and non-tool-users, and whether these differences lie in the conceptual or motor domain. We tested two species that typically do not use tools-cotton top tamarins (Saguinus oedipus) and vervet monkeys (Cercopithecus aethiops)-on problems that mirrored those designed for prolific tool users such as chimpanzees. We trained subjects on a task in which they could choose one of two canes to obtain an out-of-reach food reward. After training, subjects received several variations on the original task, each designed to examine a specific conceptual aspect of the pulling problem previously studied in other tool-using species. Both species recognized that effective pulling tools must be made of rigid materials. Subsequent conditions revealed significant species differences, with vervets outperforming tamarins across many conditions. Vervets, but not tamarins, had some recognition of the relationship between a tool's orientation and the position of the food reward, the relationship between a tool's trajectory and the substance that it moves on, and that tools must be connected in order to work properly. These results provide further evidence that tool-use may derive from domain-general, rather than domain-specific cognitive capacities that evolved for tool use per se.
