We evaluated over 200 participants semiannually from 12 to 48 months of age on measures of intellectual (Bayley Scales, Stanford-Binet Scale) and verbal (MacArthur-Bates Inventory, Peabody Picture Vocabulary Test) status. Structural equation modeling and hierarchical linear (growth curve) analyses were applied to address the nature of development…

This study examined the second language (L2) development of adult learners of Spanish at three levels of proficiency during and after a semester of instruction. A fundamental goal was to identify cognitive and psychosocial individual differences (IDs) that can explain between-learner variation over time in order to expand our understanding of the…

In this study, 600 school teachers completed a 116-item questionnaire consisting of questions regarding classroom communication as well as a general list of social skills. The aim of the study was to compare the self-perceptions, given by the teachers of art and the teachers of science and the male and female teachers to the statements of social…

This study investigates the relationship between student engagement (as measured by the National Survey of Student Engagement benchmarks) and pharmacy student professionalism (as measured by the Pharmacy Professionalism Domain instrument) in first and third year pharmacy students at seven different schools of pharmacy. Engagement provides the…

Contemporary thinking seems to be particularly interested in the investigation of the role of culture in socio-political life. This article presents aspects of a research project, undertaken in Greece, looking into whether a cultural product can foster intercultural communication and influence young people's perceptions of and attitudes to…

E-learning technologies are often seen as a driving force in the democratisation of contemporary education. However, few researchers have focused on inequalities in online learners' access to technologies or their abilities to use them. In 2009, we assessed The University of Western Australia's "SmARTS" outreach program, investigating…

In psychological research, one often aims at explaining individual differences in S-R profiles, that is, individual differences in the responses (R) with which people react to specific stimuli (S). To this end, researchers often postulate an underlying sequential process, which boils down to the specification of a set of mediating variables (M)…

The nature of fluid intelligence was investigated by identifying variables that were, and were not, significantly related to this construct. Relevant information was obtained from three sources: re-analyses of data from previous studies, a study in which 791 adults performed storage-plus-processing working memory tasks, and a study in which 236…

The relationship between love styles and lifetime number of sexual partners was explored using survey data from 507 college students. Love styles significantly (p less than 0.001) contributed to the prediction of number of lifetime sex partners after controlling for demographic characteristics and attitudes toward sexually transmitted infections.…

There is increasing evidence relating psychometric measures of general intelligence and reasoning to regional brain structure and function assessed with a variety of neuroimaging techniques. Cognitive dimensions independent of general intelligence can also be identified psychometrically and studied for any neuroanatomical correlates. Here we…

Autoantibodies to central nervous system antigens, such as myelin basic protein (MBP), may play a role in autism. We measured autoantibody titers to MBP in children with autism, both classic onset and regressive onset forms, controls (healthy age- and gender-matched) and individuals with Tourette syndrome via enzyme-linked immunosorbent assays. We…

Previous studies provide empirical support for the reported colour experience in grapheme-colour synaesthesia by measuring the synaesthetic experience from an externally presented grapheme. The current study explored the synaesthetic experience resulting from a visual mental image of a grapheme. Grapheme-colour synaesthetes (N=6) and matched…

The present paper contributes to individual difference research in the field of working memory (WM) and reasoning and their contribution to the prediction of real-life criteria. Therefore, a broad WM test battery, a well-established measure of reasoning, and school grades were applied. It is argued that abilities as assessed with the WM component…

Three experiments examined the nature of individual differences in switching the focus of attention in working memory. Participants performed 3 versions of a continuous counting task that required successive updating and switching between counts. Across all 3 experiments, individual differences in working memory span and fluid intelligence were…

The objective of this study was to investigate the effects of working memory capacity, access to subordinate meanings of L1 homonyms and degree of cross-language activation on the access to subordinate meanings of L2 homonyms. In Experiment 1, Spanish-English bilinguals completed a word recognition task which assessed how quickly and accurately…
