In all 794 young people aged around 30 yrs completed three intelligence (Raven's Progressive matrices: GMA Numerical and GMA Verbal) and one personality inventory (16PF). They were all graduates and 173 were identified clearly as Arts graduates and 518 as Science students. There were various sex differences on all measures. All seven hypotheses…

This study investigated whether individual differences in thinking styles influence explicit and implicit learning. Eighty-seven university students in China participated in this study. Results indicated that performance in the explicit learning condition was positively associated with Type I thinking styles (i.e. legislative and liberal styles)…

Experimental games like the dictator game have proven of great value for the study of altruism and sharing behavior. It has been shown that individuals differ substantially in the amount of money they offer to an anonymous receiver. Yet, to date little is known about how personality dispositions shape differences in altruistic sharing. The current…

The present study investigated individual and cross-cultural differences in statistics anxiety among 223 Turkish and 237 American college students. A 2 x 2 between-subjects factorial multivariate analysis of covariance (MANCOVA) was performed on the six dependent variables which are the six subscales of the Statistical Anxiety Rating Scale.…

The current research examines whether and how beliefs about intelligence moderate the effects of expecting rapid feedback on exam performance. Thirty-six undergraduates participated in a field experiment with two between-subjects independent variables: anticipated feedback proximity and beliefs about intelligence. The results show that expecting…

Children whose parents are more highly educated enjoy greater age-linked gains in cognitive abilities and academic achievement. Different researchers have typically focused on different outcomes, and the extent to which parental education relates to multiple child outcomes via a single developmental pathway has received little empirical attention.…

Executive functions (EF) are closely related to math performance. Little is known, however, about the role of EF in numerical magnitude skills (NS), although these skills are widely acknowledged to be important precursors of math learning. The current study focuses on the different roles of updating, shifting, and inhibition in NS. EF and NS were…

The present research investigates the role of individual differences in preference for adopting extrinsic frame of reference (EFR) in ability to represent mentally spatial information learned through survey and route descriptions. A sample of 191 participants (100 females and 91 males) was categorized as four groups with high (H-EFR), medium-high…

Few studies have identified individual differences in vocational knowledge or its association with career aspirations or expectations of children. We investigated whether individual differences in grade, gender, academic achievement, and SES predict levels of vocational knowledge, and further examined the relationship between vocational knowledge…

Previous research shows that children's ability to estimate numbers of items using their Approximate Number System (ANS) predicts later math ability. To more closely examine the predictive role of early ANS acuity on later abilities, we assessed the ANS acuity, math ability, and expressive vocabulary of preschoolers twice, six months apart. We…

In the present study, we investigated the ability of 106 (55 males, 51 females) college students to recall an 8-step path from different viewpoints (0 degrees; 90 degrees; 180 degrees and 270 degrees) after primary and secondary learning without a time limit. For each participant, we computed the time and number of repetitions necessary to learn…

Little is known about individual differences in integrating numeric base-rates and qualitative text in making probability judgments. Fuzzy-Trace Theory predicts a preference for fuzzy processing. We conducted six studies to develop the FPPI, a reliable and valid instrument assessing individual differences in this fuzzy processing preference. It…

In order to enhance our understanding of individual differences in scholastic motivation, the present study examined if social relationships in school are equally important for motivation across a large sample of adolescent students. Based on past research as well as our preliminary findings, it was hypothesized that there would be four different…

Anecdotal evidence indicates that dyslexia is positively associated with superior visuospatial ability but empirical evidence is inconsistent. We explicitly tested the hypothesis that dyslexia is associated with visuospatial advantage in 20 dyslexic and 21 unimpaired adult readers using paper-and-pencil measures and tests of "everyday"…

The purpose of this study was to identify sources of individual differences in knowledge acquired under natural conditions. Through its direct influence on background knowledge, crystallized intelligence (Gc) had a major impact on political knowledge, acquired over a period of more than 2 months, but there were independent influences of…
