A factor-analytic study of creative-thinking abilities

Fifty-three tests designed to measure aspects of creative thinking were administered to 410 air cadets and student officers. The scores were intercorrelated and 16 factors were extracted. Orthogonal rotations resulted in 14 identifiable factors, a doublet, and a residual. Nine previously identified factors were:verbal comprehension, numerical facility, perceptual speed, visualization, general reasoning, word fluency, associational fluency, ideational fluency, and a factor combining Thurstone'sclosure I andII. Five new factors were identified asoriginality, redefinition, adaptive flexibility, spontaneous flexibility, andsensitivity to problems.Under Contract N6onr-23810 with the Office of Naval Research.

A second-order factor analysis of reasoning abilities

This article reports a second-order factor analysis of the 13 interpretable first-order factors of Adkins and Lyerly based on 66 variables for 200 Army men. The approach to simple structure for 6 second-order factors was unusually good. Loadings of the original 66 variables on the second-order factors were also obtained. Five of the factors are tentatively interpreted as Precision in Formation and Use of Verbal Concepts, General Verbal Fluency, Visualizing Spatial Constancy During Movement, Speed in Analysis, and Flexibility in Analysis.     

A factor-analytic study of measures of Machiavellianism

Three Machiavellian (Mach) scales together with measures of authoritarian personality, the EPQ and the 16PF test were subjected to a rotated factor analysis in order to identify and locate in personality space a Mach factor or factors. One Mach factor was identified independent of the main personality factors.     

A study of disjunctive reasoning

Summary Whilst it is currently fashionable to construct sequential models of reasoning, the results of recent experiments on conditional reasoning tasks are apparently incompatible with this notion. There is evidence of two orthogonal statistical components, one logical and the other non-logical. It has been suggested that non-logical tendencies are response biases independent of the linguistic structure of the rule. However, certain results suggest that the matching bias observed in conditional tasks may not occur with disjunctives.Two experiments are reported in which subjects generated subjective truth tables for disjunctive rules, in which the presence and absence of negative components was varied. Experiment I provided a powerful test of the matching bias hypothesis and found no evidence of its presence. The presence of negative components did, however, systematically affect performance. Experiment II, with the aid of latency measurements, provided support for the hypothesis that negatives were affecting the ease of interpretation of the disjunctive sentences, with one negative component causing at least as much difficulty as two.In discussion, it is pointed out that the present results can be reconciled with those on conditional tasks, on the assumption that matching bias is a special case of associational biases which are dependent on the linguistic form of the rule. It still appears necessary to retain the distinction between logical and non-logical components of the performance. However, this does not necessarily imply parallel processes underlying the data. A single muddled thought process, in which a rational sequential strategy fails to be consistently applied, could give rise to the type of data obtained.     

Using domain-general principles to explain children's causal reasoning abilities

A connectionist model of causal attribution is presented, emphasizing the use of domain-general principles of processing and learning previously employed in models of semantic cognition. The model categorizes objects dependent upon their observed 'causal properties' and is capable of making several types of inferences that 4-year-old children have been shown to be capable of. The model gives rise to approximate conformity to normative models of causal inference and gives approximate estimates of the probability that an object presented in an ambiguous situation actually possesses a particular causal power, based on background knowledge and recent observations. It accounts for data from three sets of experimental studies of the causal inferencing abilities of young children. The model provides a base for further efforts to delineate the intuitive mechanisms of causal inference employed by children and adults, without appealing to inherent principles or mechanisms specialized for causal as opposed to other forms of reasoning.     

A computer-based test battery for the assessment of static and dynamic spatial reasoning abilities

A battery of 10 computerized tests of spatial ability is described. It includes 5 tests that require reasoning about static spatial displays and 5 tests that require reasoning about dynamically displayed spatial information. An integrated software package for task presentation and data analysis is described, along with a summary of results from a validation study comparing performance on the computer-based tests with performance on standardized paper-and-pencil tests of spatial abilities. Finally, research applications of the current battery are discussed.     

Contribution of sex-differentiated experiences to spatial and mechanical reasoning abilities

For 137 women and 115 men first-year college students tested spatial visualization and mechanical reasoning were most strongly correlated with four everyday spatial abilities--understanding mathematics/science and graphs/charts, drafting and drawing things, and arranging objects. Despite greater practice on only 2 of 10 activities, men uniformly judged they had significantly better spatial ability compared to their same-gender peers than did the women.     

Left-handedness and spatial reasoning abilities: The deficit hypothesis revisited

Left-handers with an inverted handwriting posture have been found by Levy and Reid to have relatively bilateral representation of tachistoscopically tested verbal and spatial functions. On the assumption that such bilateral representation is inefficient, it was hypothesized that left-inverted subjects (N = 20) would score lower than left- and right-handers with normal handwriting postures (Ns = 64, 66 respectively) on spatial reasoning. Results were consistent with the hypothesis. Possible alternative explanations and directions for future research are outlined.     

Effects of adult age and working memory on reasoning and spatial abilities

Three predictions were derived from the hypothesis that adult age differences in certain measures of cognitive functioning are attributable to age-related reductions in a processing resource such as working-memory capacity. Each prediction received at least some degree of empirical support in a study involving 120 males ranging between 20 and 79 years of age. First, older adults exhibited greater impairments of performance than did young adults when task complexity increased and more demands were placed on the limited processing resources; second, the magnitudes of these complexity effects were highly correlated across verbal (reasoning) and spatial (paper folding) tasks. Finally, statistical control of an index of a working-memory processing resource attenuated the effects of age on the measures of cognitive performance. It was concluded that further progress in understanding the mechanisms of the relation between age and cognitive functioning will require improved conceptualizations of the nature of working memory or other hypothesized mediating constructs.     

The facilitatory effect of negative feedback on the emergence of analogical reasoning abilities

This paper focuses on the development of analogical reasoning abilities in 5‐ and 6‐year‐old children. Our particular interest relates to the way in which analogizing is influenced by the provision of task‐based feedback coupled with a self‐explanation requirement. Both feedback and self‐explanation provide children with opportunities to engage in self‐reflective thinking about the process of analogical reasoning. To examine the role of such metacognitive factors in analogical strategy development the reported study combined a proportional analogy paradigm with a small‐scale microgenetic approach involving multiple testing sessions over a restricted time period. The key manipulation involved exposing participants either to the correct or incorrect analogy completions of another reasoner that they were then asked to explain. The data revealed that the development of an effective analogizing strategy embodying a ‘relational shift’ from superficial to relational responding was modulated by the feedback condition that the child was placed in, with a negative feedback intervention providing the greatest developmental benefit. We suggest that the value of negative feedback for the acquisition of analogical reasoning abilities derives from the way in which a self‐reflective analysis of the reasons for erroneous responses sensitizes the child to a deeper understanding of how to make effective relational mappings.     

A factorial study of the reasoning and closure factors

A battery of 46 tests was given to 237 college men. A factor analysis using the Thurstone technique revealed eight clearly interpretable first-order factors, one dubious factor, and a residual factor. The factors were interpreted as induction, deduction, flexibility of closure, speed of closure, space, verbal comprehension, word fluency, and number. Four second-order factors were abstracted from the matrix of first-order correlations. The presence of induction, deduction, and flexibility of closure on the first second-order factor, interpreted as an analytic factor, confirmed previous indications of relationships between the reasoning and closure factors. A second bipolar factor is interpreted as a speed of association factor. The third factor is interpreted as facility in handling meaningful verbal materials—perhaps an ability to do abstract thinking. The fourth factor is possibly a second-order closure factor—perhaps an ability to do concrete thinking.The author is grateful to Professor L. L. Thurstone for his encouragement and invaluable advice and for permission to use many tests originally prepared in the Psychometric Laboratory of the University of Chicago, to Mr. James Degan for assistance in rotations, and to the Social Science Research Committee of the University of Chicago for a grant to this study.     

Young Humeans: the role of emotions in children's evaluation of moral reasoning abilities

Three experiments investigated whether children in grades K, 2, and 4 (n = 144) view emotional comprehension as important in solving moral dilemmas. The experiments asked whether a human or an artificially intelligent machine would be best at solving different types of problems, ranging from moral and emotional to nonmoral and pragmatic. In Experiment 1, children in all age groups indicated that a human would be superior to a computer not only at comprehending emotions, but also at solving moral dilemmas. In Experiment 2, older children also indicated that a human could solve moral dilemmas better than a 'robot' with human-like perceptual and physical abilities. Experiment 3 further demonstrated that these effects were not solely due to a bias towards humans. Thus, children as young as age 5 view emotional understanding as an important element for moral, but not for nonmoral, reasoning, suggesting that the basis for Humean intuitions emerges early in life.     

The ABCs of analogical abilities: Evidence for formal analogical reasoning abilities in 24‐month‐olds

Solving formal analogy problems requires the identification of an initial term and the transformation that occurs between the initial two terms as well as the determination of the final term. Experiment 1 tested 24‐month‐olds' ability to determine final terms when they were shown the initial term and told the transformation that was to occur. Children selected their responses from an array of two principled distracters. The children were able to determine the correct final term when they were given information about the initial term and transformation. Experiment 2 tested 24‐month‐olds' ability to solve final‐term problems, partial analogies, and complete analogies. The children solved all the three types of problems.     

A parent-offspring adoption study of cognitive abilities in early childhood

Do cognitive abilities in early childhood relate genetically and/or environmentally to isomorphic abilities in adulthood? Are specific cognitive abilities diffentiated in early childhood in terms of their prediction of adult cognitive abilities? The present study, the first behavioral genetic analysis of specific cognitive abilities in early childhood, explored these questions using parent-offspring data for 186 adopted children and 151 nonadopted children tested in the longitudinal Colorado Adoption Project at 3 years of age and 162 adopted children and 138 nonadopted children tested at 4 years. The children's Stanford-Binet IQ and scores for four specific cognitive abilities (verbal, spatial, perceptual speed, and memory) were correlated with corresponding measures for their parents—the biological and adoptive parents of the adopted children and the natural parents of the nonadopted children. Significant correlations were found between biological mothers' IQ and the IQ of their adopted away offspring at 3 and 4 years of age, suggesting genetic influence for IQ. However, specific cognitive abilities yielded no significant correlations between biological mothers and their adopted-away offspring. These results suggest that substantial genetic continuity exists for IQ from early childhood to adulthood, but not for specific cognitive abilities.     

Semantic, executive, and visuospatial abilities in mathematical reasoning of referred college students

Semantic retrieval (SR) and executive-procedural (EP), but not visuospatial (VS) skills, have been found to be uniquely predictive of mathematical calculation skills in a sample of clinically referred college students. This study set out to cross-validate these results in an independent sample of clinically referred college students (N = 337) as well as extend them by examination of the contributions of these cognitive domains to math reasoning skills. Results indicate that these cognitive domains were able to predict 30% of the variance in calculation skills and 50% of the variance in math reasoning; however, in both cases, only the domains of semantic retrieval and visuospatial skill contributed uniquely. Differences between studies, and the lack of unique contribution of the EP domain to either type of math skill, may be due to measurement and sampling differences, the degree of shared relations among domains, and the choice of measures that represent the EP domain. Implications and future directions are explored.
