Does Socio-Economic Status Have Different Impact on Fluid and Crystallized Abilities? Comparing Scores on Raven's Progressive Matrices, Kaufman Assessment Battery for Children II Story Completion and Kilifi Naming Test Among Children in Ghana.

Current literature shows an association between intelligence and socio-cultural or socio-economic factors. The available evidence supports a stronger effect of exogenous factors on measures of crystalized intelligence than on fluid intelligence. Despite this, the sources of variability in fluid and crystalized intelligence have not been explored adequately in intelligence research. The purpose of this study was to compare performance on tests that measure fluid and crystallized intelligence among children selected from public and private schools in Ghana. We tested the assumption that socio-economic status (SES) will have a stronger effect on tests that measure crystallized intelligence than on fluid intelligence. We selected 185 children between 6 and 12 years from private and public schools, and used inclusion in a private or public school as a proxy for SES. We administered the Raven’s Coloured Progressive Matrices (RCPM), a fluid intelligence test, the KABC II story completion subtest as a measure of inductive reasoning and crystallized intelligence and the Kilifi Naming Test, a verbal ability measure designed to minimize the effect of school on vocabulary. The results showed age-related improvement in scores on all three tests with effect sizes ranging from 0.42 to 0.52. We also found significant effect for type of school on all the tests with effect sizes ranging from 0.37 to 0.66. The results also showed an increasing disparity in performance on the tests favoring children selected from private schools. These suggest that fluid and crystalized intelligence are affected by socioeconomic factors. The results also showed that SES factors tend to affect crystallized ability more than it affects fluid ability. The results are discussed in the context of differences in socioeconomic resources available to children such as quality of education in low- and middle-income countries.

Voice Biomarkers as Possible Indicators of Cognitive Aging

There is emerging evidence that measures of voice prosody are related to diagnoses of Alzheimer’s Disease and Related Disorders. The goal of this study was to examine whether voice prosody measures (pitch, pulse, voice breaks, jitter, shimmer, and amplitude) are also related to individual differences in normal cognitive aging. Data are from the Midlife in the United States Wave 2 (M2) and Wave 3 (M3) for 2693 participants (ages 42-92 at M3) who completed the M2 and M3 Brief Test of Adult Cognition by Telephone (BTACT) and had M3 voice recordings. Voice variables were measured from cognitive interviews using three cognitive tests and averaged to create a composite for each voice variable. Voice prosody was related to age, sex, education, and health, which were included as covariates. Older adults, men, and those with more health conditions had higher jitter and shimmer. Older adults, women, and those with higher education and better health had more voice breaks. Hierarchical regression models, controlling for the covariates, examined the voice composites as predictors of each cognitive measure at M3 and change over 9 years from M2 to M3. As hypothesized, higher jitter predicted lower performance and greater decline on memory, category fluency, and attention. Contrary to predictions, a lower number of voice breaks predicted worse performance and greater declines on all cognitive tests. The results suggest that voice biomarkers are related to cognitive performance and decline, and they may offer a promising approach for identifying early signs of cognitive impairment or dementia.

Education Differences in Older Adults' Performance on Online Assessments of Inductive Reasoning and Verbal Memory

Paper-and-pencil measures of inductive reasoning and verbal memory administered in-person are well-established methods for measuring cognitive ability in adults. However, given recent increases in the use of online surveys, particularly during the COVID-19 pandemic when in-person research with older adults became difficult, we investigated whether these cognitive measures could be administered effectively online and whether older adults’ performance on these measures of inductive reasoning and verbal memory might differ by education level. Data were collected online between mid-May and mid-June of 2020 from 292 individuals aged 66-90 years (M=69.1, SD=3.3). The sample was primarily White (91%) and had more women (62%) than men; 83 participants had a graduate-level education (master’s/doctoral degree), 101 had an associate’s or bachelor’s degree, and 108 had less than an associate’s degree. Three measures of inductive reasoning (Number Series, Letter Sets, and Word Series) and two measures of verbal memory (Immediate Recall and Delayed Recall of a list of 20 words) were completed by participants on an online platform. One-way MANOVA found a significant main effect for education group on the inductive reasoning measures (Wilks’ lambda=.93, p=.001). However, follow-up univariate ANOVAs indicated significant differences by education group only for Number Series, with Tukey post hoc tests showing that the graduate-level and college-degree groups performed significantly better than the group with less than an associate’s degree. Factorial repeated-measures ANOVA found a significant decline between immediate and delayed recall (p<.001) and that this difference varied by education group (p=.003). Implications of these findings will be discussed.

Construction and validation of a game-based intelligence assessment in minecraft

Video games are a promising tool for the psychometric assessment of cognitive abilities. They can present novel task types and answer formats, they can record process data, and they can be highly motivating for test takers. This paper introduces the first game-based intelligence assessment implemented in Minecraft, an exceptionally popular video game with more than 200 m copies sold. A matrix-based pattern completion task (PC), a mental rotation task (MR) and a spatial construction task (SC) were implemented in the three-dimensional, immersive environment of the game. PC was intended as a measure of inductive reasoning, whereas MR and SC were measures of spatial ability. We tested 129 children aged 10–12 years old on the Minecraft-based tests as well as equivalent pen-and-paper tests. All three scales fit the Rasch model and were moderately reliable. Factorial validity was good with regard to the distinction between PC and SC, but no distinct factor was found for MR. Convergent validity was good as abilities measured with Minecraft and conventional tests were highly correlated at the latent level (r = 0.72). Subtest-level correlations were in the moderate range. Furthermore, we found that behavioral log-data collected from the game environment was highly predictive of performance in the Minecraft test and, to a lesser extent, also predicted scores in conventional tests. We identify a number of behavioral features associated with spatial reasoning ability, demonstrating the utility of analyzing granular behavioral data in addition to traditional response formats. Overall, our findings indicate that Minecraft is a suitable platform for game-based intelligence assessment and encourage future work aiming to explore game-based problem solving tasks that would not be feasible on paper or in conventional computer-based tests.

Sex differences in inductive reasoning: A research synthesis using meta-analytic techniques

Meta-analyses concerning sex differences in measures of fluid ability have been limited to discussions of sex differences in the Raven's Progressive Matrices, a measure of inductive reasoning. This study synthesized data concerning sex differences on several different types of inductive reasoning tests in order to assess the evidence for an overall sex difference in manifest scores, as well as whether the magnitude of the sex difference may vary depending on certain test characteristics such as stimuli and item type. Meta-analytic techniques were used to summarize data concerning sex differences in inductive reasoning from 98 studies reporting data from 96,957 adults with mean ages 18 to 64 years. The overall summary effect size was g = +0.13 (range −0.54 to +0.68), however there was significant variation in the magnitude, and in some cases direction, of the effect size in measures of inductive reasoning. Some implications of this variation in the effect size of the sex difference across tests are discussed in light of theoretical interpretations and practical uses.

Impaired option generation underpins deficient reasoning in Parkinson’s disease patients with apathy

Apathy is a debilitating neurological syndrome known to be associated with executive dysfunction, particularly affecting abstract reasoning. However, the underlying cognitive mechanism remains unclear. Recently, it has been proposed that one cognitive process disrupted in apathy is option generation. We investigated whether impaired option generation could explain deficient reasoning in apathy. Data was retrospectively analyzed from patients with Parkinson’s disease (n = 51) who had completed the Lille Apathy Rating Scale and the Brixton Spatial Anticipation Task (Brixton), a measure of inductive reasoning. A hierarchical regression analysis showed that higher levels of apathy predicted poorer Brixton performance. Detailed analysis of Brixton errors was conducted to investigate the cognitive process underlying this relationship. Additional hierarchical regression analyses showed that apathy specifically predicted Brixton errors associated with a failure to generate either correct or incorrect rules. These findings suggest that deficient reasoning in apathy may be underpinned by impaired option generation.

Dimensionality of the Raven's Advanced Progressive Matrices: Sex differences and visuospatial ability

Raven's progressive matrices are considered a measure of inductive reasoning. However, there is evidence to suggest that they are not unidimensional, and they may measure visuospatial ability in addition to inductive reasoning. We investigated the psychometric properties of several versions of the Advanced Progressive Matrices (APM). Confirmatory factor analyses and Rasch analyses were used to investigate the dimensionality of the test, sex differences regarding dimensionality, and the utility of proposed taxonomies of item solution strategies. Three samples were administered three different forms of the test. Sample 1 consisted of 1297 individuals (929 females) who completed a 12-item short form; Sample 2 consisted of 455 individuals (327 females) who completed the full APM; and Sample 3 consisted of 362 individuals (244 females) who completed a 15-item short form. Results indicated that all three forms of the APM are unidimensional and measurement invariant across sex. There was little support for the validity of the taxonomies of solution strategies.

Cognitive predictors and age-based adverse impact among business executives.

Age differences on measures of general mental ability and specific cognitive abilities were examined in 2 samples of job applicants to executive positions as well as a mix of executive/nonexecutive positions to determine which predictors might lead to age-based adverse impact in making selection and advancement decisions. Generalizability of the pattern of findings was also investigated in 2 samples from the general adult population. Age was negatively related to general mental ability, with older executives scoring lower than younger executives. For specific ability components, the direction and magnitude of age differences depended on the specific ability in question. Older executives scored higher on verbal ability, a measure most often associated with crystallized intelligence. This finding generalized across samples examined in this study. Also, consistent with findings that fluid abilities decline with age, older executives scored somewhat lower on figural reasoning than younger executives, and much lower on a letter series test of inductive reasoning. Other measures of inductive reasoning, such as Raven's Advanced Progressive Matrices, also showed similar age group mean differences across settings. Implications for employee selection and adverse impact on older job candidates are discussed.

Cognitive training for children: Effects on inductive reasoning, deductive reasoning, and mathematics achievement in an Australian school setting

Inductive reasoning is a core cognitive process of fluid intelligence, predicting a variety of educational outcomes. The Cognitive Training for Children (CTC) program is an educational intervention designed to develop children's inductive reasoning skills, with previous investigations finding substantial effects of the program on both inductive reasoning ability and classroom learning. The present study assessed both individual and small‐group CTC training against a no‐treatment control condition to investigate the effects on inductive and deductive reasoning and mathematics achievement in a primary school‐aged Australian cohort. Students who received individual training outperformed those in the control condition on measures of inductive and deductive reasoning, and those in the small‐group condition also outperformed the control condition on a measure of inductive reasoning 3 months following training. However, hypotheses regarding transfer effects to mathematics achievement were not supported. Directions for future research, focusing on extended longitudinal studies and motivational variables, are discussed.

The correlation of inductive reasoning with multi-dimensional perception

Intelligence correlated with perception in previous studies. The aim of this investigation was to specify the relationship between inductive reasoning and perception. For this purpose, 125 healthy adults performed the Raven’s Advanced Progressive Matrices as measure of inductive reasoning and six perception tasks. Inductive reasoning correlated with simultaneous perception of locus and pitch (r=.29, p<.001) and with perception of four distinct colors (r=.32, p<.001). Inductive reasoning was not significantly associated with pitch discrimination, pitch contour perception after partialing out effects of covariates, pitch identification, and visual localization. Inductive reasoning, locus-pitch perception, and color perception required the processing of unrelated categories. Therefore, inductive reasoning and the correlating perception skills may share multi-dimensional mental representation. This multi-dimensional representation may differ from one-dimensional scales such as pitch. The findings suggest a differentiation of pre-semantic cognitions and its interactions with perception.

Openness to experience and activity engagement facilitate the maintenance of verbal ability in older adults.

The current study used data from the Aberdeen Birth Cohort, 1936, to investigate the hypothesis that the positive effects of the personality trait Openness on cognitive ability are mediated by activity levels. Results of latent growth modeling analysis revealed that higher Openness predicted better reading ability, inductive reasoning, and memory performance across three testing occasions when participants were aged 64-68 years. Higher Openness predicted higher activity levels, and higher activity levels in turn predicted higher reading ability, but not higher performance on measures of inductive reasoning, memory, and speed of processing. Overall, Openness and activity engagement appear related to preserved higher cognitive ability in older adults, with Openness having a direct effect on marker tests of fluid ability and with the combined influence of Openness and activity being particularly important for marker tests of crystallized intelligence.

Socioeconomic status moderates the association between carotid intima-media thickness and cognition in midlife: Evidence from the Whitehall II study

BackgroundCommon carotid artery intima-media thickness (IMT) is a measure of generalized atherosclerosis and has been shown to be associated with cognitive function. We examine two questions: does socioeconomic status (SES) moderate this association and is IMT more strongly associated with specific aspects of cognitive function? MethodsData are drawn from the Phase 7 (2003–2004) of the Whitehall II study (N=3896). In cross-sectional analyses the association between IMT and six measures of cognition (short-term verbal memory, inductive reasoning, vocabulary, semantic and phonemic fluency and a measure of global cognitive status) was examined in analyses adjusted for previous history of coronary heart disease, health behaviours and other vascular risk measures such as blood pressure, cholesterol and body mass index. ResultsThe overall association between IMT and the six measures of cognition was restricted to the low SES group (p=0.02). Within this group, IMT was significantly associated with inductive reasoning (p=0.001), vocabulary (p=0.002), phonemic (p=0.006) and semantic fluency (p=0.02). The covariates examined explained about a quarter of the association between IMT and cognition in the low SES group. The associations with the measure of inductive reasoning (p=0.02), vocabulary (p=0.02) and phonemic fluency (p=0.04) remained after adjustment for all covariates. ConclusionsSES is an important modifier of the association between IMT and cognition, an inverse association between the two was observed only in the low SES group. It is possible that high cognitive reserve among the high SES individuals prevents the functional manifestations of atherosclerosis. Verbal memory was not one of the cognitive domains associated with IMT.

Inductive reasoning and the understanding of intention in schizophrenia

Background. The study explored the relationship between the understanding of intention in veiled speech acts and the ability to reason inductively. Methods. A total of 39 people with DSM-IV-defined schizophrenia with no behavioural signs and 44 healthy participants performed the Hinting Task, a measure of pragmatic language in which the speaker's intention must be inferred, and a measure of inductive reasoning (Aha! Sentences) in which the meaning of ambiguous nonsocial sentences had to be inferred. The participants also completed measures of general intellectual ability, immediate memory for narrative and social problem-solving ability. Results. A substantial correlation was found between performance on the inductive reasoning task and the Hinting Task in the sample of people with schizophrenia. The same relationship was not seen in the normal control sample. The robust relationship between these two measures in this sample survived when the roles of immediate memory for narrative and intellectual ability were controlled for. Furthermore, the relationship was distinctly more compelling for the patients who were currently ill compared to those in remission. Results. These data suggest that people with schizophrenia use a different strategy to infer the meaning behind pragmatic language than that used by normally functioning adults. It is suggested that a reliance on different, possibly less specialised, skills in this group to perform this simple social inference task underlies their deficient performance on this and other measures of social inference. The fact that the relationship between the tasks in patients in remission is not as robust implies that the use of specialised skills to perform social inference tasks may be compromised most significantly during acute phases.

Locus of Control, Expectational Set, and Problem Solving

The purpose of this study was to investigate whether experimentally induced expectational sets of success or failure differentially affect the performance of internal and external scorers. Another purpose was to determine the relation between locus of control and verbal and figural measures of inductive reasoning. Subjects were 144 fifth graders who were administered the children's Nowicki-Strickland instrument. Analysis indicated that the external scorers' mean was significantly lower than that of internal scorers on a verbal problem-solving task. Experimenter's instructions did not differentially affect performance on the two types of tasks and did not differentially affect the two groups of scorers.

Inferences about age impairments in inferential reasoning.

Two experiments are reported in which specially constructed series completion tests were administered to samples of young and older adults to determine why increased age is associated with poorer performance on measures of inductive reasoning. The results indicated that young and older adults did not differ significantly in the effectiveness of processes concerned with determining simple relations, but that older adults were impaired when the relations are complex or when different problems involve alternative organizational patterns. We conclude that the poorer performance of older adults relative to young adults on tasks of this type may be due to inadequate (e.g., overly simplistic or temporally instable) relational structures for the integration of problem elements.
