Cognitive processing in specifically language-impaired children

Eighteen language-impaired children and 25 non-language-impaired children were evaluated to investigate the relationship between language ability and selected aspects of the five-component problem-solving process defined by Kagan and Kogan (1970). Non-impaired children performed better than language-impaired children on nearly all components of the problem-solving process. Language-impaired children had particular difficulties in the areas of coding and hypothesis generation. In fact, coding ability was inversely related to the number of errors made in hypothesis evaluation. Coding ability was also positively correlated with language ability. The exact causal relationship between coding ability, language ability, and error-making in hypothesis evaluation is unclear; however, improving coding skills through training may increase automaticity and lead to improved performance in the higher levels of the problem-solving process.

The common factors in fifty-two mental tests

An analysis by Thurstone's centroid method of the intercorrelations of fifty-two tests was carried to ten factors. Included were tests of social intelligence, Philip's attention tests, and Seashore's tests of musical ability. After rotation of axes, the most important factors appeared to pertain to operations conventionally alluded to by the following terms: verbal facility; spatial ability; numerical ability; attention; musical ability; and memory (or memory span). The social intelligence tests proved to be mainly tests of the verbal factor. A factorial sex difference was indicated by the superiority of men in tests of spatial ability.     

Gender Differences in Persistence and Attributions in Stereotype Relevant Contexts

The present research was designed to examine the effects of gender math stereotypes on performance attributions and persistence. Two experiments tested whether stereotypes guided men’s and women’s reactions to negative or positive feedback on an alleged test of verbal or math ability. In Study 1, attributions to ability were influenced by gender stereotypes: women were more sensitive to feedback on a test that was described as a test of their math ability than when the same test was described as a test of their verbal ability, whereas men showed the opposite pattern. Study 2 replicated these findings for negative feedback and further showed that gender differences in attributions to ability mediated the gender difference in persistence in the math domain following an alleged failure on a math test. The implications of stereotype-consistent attributions for women’s persistence in quantitative fields are discussed.     

Individual differences in spatial learning from computer-simulated environments

A multivariate study examined relationships between the following factors: paper-and-pencil assessments of verbal and spatial ability, ability to form an accurate spatial representation of a large real-world environment, gender, computer attitudes and experience, proficiency with the navigational interface of a virtual environment (VE), and the ability to acquire and transfer spatial knowledge from a VE. Psychometrically assessed spatial ability and proficiency with the navigational interface were found to make substantial contributions to individual differences in the ability to acquire spatial information from a VE. Gender influenced many VE-related tasks, primarily through its relationship with interface proficiency and spatial ability. Measures of spatial knowledge of a VE maze were highly predictive of subsequent performance in a similar real-world maze, suggesting that VEs can be useful for training people about real-world spaces.     

Individual differences in deductive reasoning

Three studies are reported, which examined individual differences in deductive reasoning as a function of intellectual ability and thinking style. Intellectual ability was a good predictor of logical performance on syllogisms, especially where there was a conflict between logic and believability. However, in the first two experiments there was no link between ability and performance on indicative selection tasks, in sharp contrast to previous research. This correlation did, however, return in the final study. Our data are consistent with the claim that the correlation with logical accuracy on abstract selection tasks is found primarily with participants of relatively high ability. At lower levels, pragmatically cued responses are given but those of slightly higher ability divorce the rule from the scenario and respond consistently (though incorrectly) across problems. Self-report questionnaires were generally poor predictors of performance, but a measure of the ability to generate alternative representations proved an excellent predictor. These results are consistent with a mental models approach to reasoning and also have implications for the debate about human rationality.     

Individual differences in religiosity as a function of cognitive ability and cognitive style

The current study examines the degree to which individual differences in cognitive ability and cognitive style (rational thinking vs. experiential thinking) uniquely and jointly account for differences in religiosity. Using an array of measures of religiosity, results show that cognitive ability has a medium to large negative effect on various aspects of religiosity. Though also negatively related to religiosity, rational thinking style did not add significant unique effects, nor did it convey a significant indirect effect from cognitive ability. Experiential thinking was generally unrelated to ability but was positively related to some aspects of religiosity. Overall the results confirm that those with higher cognitive ability are less likely to accept religious doctrine or engage in religious behaviors and those with lower ability are more likely to accept religious doctrine and exhibit higher levels of fundamentalism. Cognitive style appears to play a lesser role in explaining individual differences in religiosity than cognitive ability.     

The impact of beliefs about face recognition ability on memory retrieval processes in young and older adults

This study examined whether beliefs about face recognition ability differentially influence memory retrieval in older compared to young adults. Participants evaluated their ability to recognise faces and were also given information about their ability to perceive and recognise faces. The information was ostensibly based on an objective measure of their ability, but in actuality, participants had been randomly assigned the information they received (high ability, low ability or no information control). Following this information, face recognition accuracy for a set of previously studied faces was measured using a remember–know memory paradigm. Older adults rated their ability to recognise faces as poorer compared to young adults. Additionally, negative information about face recognition ability improved only older adults' ability to recognise a previously seen face. Older adults were also found to engage in more familiarity than item-specific processing than young adults, but information about their face recognition ability did not affect face processing style. The role that older adults' memory beliefs have in the meta-cognitive strategies they employ is discussed.     

The Role of Cognitive Ability Tests in Employment Selection

Cognitive ability tests correlate with measures of job performance across many jobs. However, cognitive ability tests produce racial differences that are 3 to 5 times larger than other predictors-such as biodata, personality inventories, and the structured interview-that are valid predictors of job performance. Given that (a) cognitive ability tests can be combined with other predictors such that adverse impact is reduced while overall validity is increased, and (b) alternative predictors with less adverse impact can produce validity coefficients comparable to those obtained with cognitive ability tests alone, sole reliance on cognitive ability tests when alternatives are available is unwarranted.     

Cognitive ability and political beliefs in the United States

Recent evidence indicates that cognitive ability has a monotonically positive relation to socially liberal beliefs and some measures of fiscally conservative beliefs, and that it has a non-monotonic relation to other measures of fiscally conservative beliefs. This study examines the relationship between cognitive ability and political beliefs in a recent, nationally representative sample of American adults. It finds that cognitive ability is positively associated with both socially liberal beliefs and fiscally conservative beliefs. The relationships with socially liberal beliefs are monotonically positive. In contrast, some of the relationships with fiscally conservative beliefs are non-monotonic: Americans of highest ability are less fiscally conservative than those of high ability. The association between cognitive ability and a dimension of fiscal conservatism is reduced substantially when controlling for socio-economic position.

Relating inter-individual differences in metacognitive performance on different perceptual tasks

Human behavior depends on the ability to effectively introspect about our performance. For simple perceptual decisions, this introspective or metacognitive ability varies substantially across individuals and is correlated with the structure of focal areas in prefrontal cortex. This raises the possibility that the ability to introspect about different perceptual decisions might be mediated by a common cognitive process. To test this hypothesis, we examined whether inter-individual differences in metacognitive ability were correlated across two different perceptual tasks where individuals made judgments about different and unrelated visual stimulus properties. We found that inter-individual differences were strongly correlated between the two tasks for metacognitive ability but not objective performance. Such stability of an individual’s metacognitive ability across different perceptual tasks indicates a general mechanism supporting metacognition independent of the specific task.     

Characteristics of 12th-grade students seriously deficient in spatial ability

When spatial ability was regressed on a measure of general intelligence in a large national sample of 12th-graders, there was a distinct downturn in the regression line at about -2 SD units. A bimodal distribution of spatial ability was found among these low scoring students, suggesting 2 qualitatively different types of individuals. Relative to students of expected spatial ability, those below expected in spatial ability were high on verbal skills and low on performance skills. Students unexpectedly low in spatial ability performed relatively well on cognitive tests that required answering unambiguous questions by retrieving information directly from long term memory, whereas they performed relatively poorly on tests requiring inference and perception of relations among novel stimuli. Students unexpectedly low in spatial ability performed especially poorly at tests involving visual-spatial perception skills. Results were similar for both sexes. The relatively poor performance of those unexpectedly low in spatial ability does not appear to be related to health problems, personality, interest differences, or biographical data. An organic impairment possibly related to lateralization represents a reasonable causal hypothesis for these data.     

Numerical predictors of arithmetic success in grades 1–6

Math relies on mastery and integration of a wide range of simpler numerical processes and concepts. Recent work has identified several numerical competencies that predict variation in math ability. We examined the unique relations between eight basic numerical skills and early arithmetic ability in a large sample (N = 1391) of children across grades 1–6. In grades 1–2, children's ability to judge the relative magnitude of numerical symbols was most predictive of early arithmetic skills. The unique contribution of children's ability to assess ordinality in numerical symbols steadily increased across grades, overtaking all other predictors by grade 6. We found no evidence that children's ability to judge the relative magnitude of approximate, nonsymbolic numbers was uniquely predictive of arithmetic ability at any grade. Overall, symbolic number processing was more predictive of arithmetic ability than nonsymbolic number processing, though the relative importance of symbolic number ability appears to shift from cardinal to ordinal processing.     

Accounting for individual differences in speed in the discretized signed residual time model

With advances in computerized tests, it has become commonplace to register not just the accuracy of the responses provided to the items, but also the response time. The idea that for each response both response accuracy and response time are indicative of ability has explicitly been incorporated in the signed residual time (SRT) model (Maris & van der Maas, 2012, Psychometrika, 77, 615–633), which assumes that fast correct responses are indicative of a higher level of ability than slow correct responses. While the SRT model allows one to gain more information about ability than is possible based on considering only response accuracy, measurement may be confounded if persons show differences in their response speed that cannot be explained by ability, for example due to differences in response caution. In this paper we propose an adapted version of the SRT model that makes it possible to model person differences in overall speed, while maintaining the idea of the SRT model that the speed at which individual responses are given may be indicative of ability. We propose a two-dimensional SRT model that considers dichotomized response time, which allows one to model differences between fast and slow responses. The model includes both an ability and a speed parameter, and allows one to correct the estimates of ability for possible differences in overall speed. The performance of the model is evaluated through simulation, and the relevance of including the speed parameter is studied in the context of an empirical example from formative educational assessment.     

Independent and interdependent self-construals as predictors of multicultural case conceptualization ability in counsellor trainees

This study examined the extent to which independent and interdependent self-construals were related to counsellor trainees' multicultural case conceptualization ability (i.e., ability to conceptualize clients from a multicultural perspective). Results revealed that, after accounting for race or ethnicity and prior multicultural training, counsellor trainees' self-construal scores were significantly predictive of their ability to conceptualize clients from a multicultural perspective. Specifically, independent self-construal scores were negatively related to trainees' ability to conceptualize clients from a multicultural perspective, whereas interdependent selfconstrual scores were positively associated with multicultural case conceptualization ability. Future research directions are offered.

Primacy effects in self-attribution of ability1

Primacy effects in self-attribution of ability were investigated in an experiment. Subjects' performance on a 30-item test was experimentally manipulated to reflect one of three patterns: ascending, descending, or random success. It was predicted that there would be a primacy effect in self-attribution of ability regarding the task when subjects had no previous expectation or anchor to which performance could be assimilated, but that the primacy effect would be attenuated when a previous anchor existed. The presence or absence of a prior anchor was manipulated by describing the task as either a test related to intelligence or a test of an unsual ability, unrelated to previous experience. Results supported the hypothesis that there is a primacy effect in self-attribution of ability, and that this effect occurs most strongly where an individual has no prior anchor or expectation regarding his ability.     

No Association between Music Ability and Hand Preference in Children

Hand preference was studied in 2 groups of children—children with musical ability and children without musical ability—to examine whether particular markers that may connect with handedness patterns, such as bias away from dextrality or mixed-handedness, stabilize during childhood and are associated with musical ability. Children were administered the Edinburgh Handedness Inventory to determine levels of right, left, and mixed handedness. Results demonstrated no differences in hand preference between both cohorts of children, suggesting the relative independence of musical ability and handedness. However, the inclusion of handedness as a motor marker for musical ability in children in conjunction with other preexisting neurocognitive factors cannot be entirely discounted.     

Parental ability,education and occupation as influences on offspring cognition in Hawaii and Korea

Partial correlation procedures were used to assess the separate influences of parental ability and parental status (as measured by educational and occupational attainment) on offspring ability, using data acquired from persons of European and Japanese ancestry residing in Hawaii and from Koreans residing in Korea. The magnitudes of the correlations of parental ability and attainment with offspring ability varied substantially across groups. Partial correlations indicate that parent ability and parent status each independently influence offspring performance on measures of cognition, but that the influence of status generally is far weaker than is the influence of parental cognitive ability.
