Right hemispheric dominance in unconscious emotional processing has been suggested, but remains controversial. This issue was investigated using the subliminal affective priming paradigm combined with unilateral visual presentation in 40 normal subjects. In either left or right visual fields, angry facial expressions, happy facial expressions, or…

The study explored whether children with high functioning autism (HFA), Asperger syndrome (AS), and pervasive developmental disorder not otherwise specified (PDD-NOS) can be differentiated on the Children's Communication Checklist (CCC). The study also investigated whether empirically derived autistic subgroups can be identified with a cluster…

Biological phenomena can be investigated at multiple levels, from the molecular to the cellular to the organismic to the ecological. In typical biology instruction, these levels have been segregated. Yet, it is by examining the connections between such levels that many phenomena in biology, and complex systems in general, are best explained. We…

A meta-analysis in the form of Brinley plots was conducted on the mean reaction times of Attention Deficit Hyperactivity Disorder (ADHD) and Control groups of children and adolescents on the Stroop Color and Word Test (SCWT). ADHD reaction times were regressed on Control group reaction times for 17 data sets (accessed from 13 published studies).…

A large number of national and geographic population samples were used to test the hypothesis that the variation in mean values of skin color in the diverse populations are consistently correlated with the mean measured or estimated IQs of the various groups, as are some other physical variables, known as an ecological correlation. Straightforward…

This study examined whether children's inferential styles moderate the association between the onset of depressive symptoms in children and their parents. To provide a powerful test of our hypotheses, we utilized a high-risk sample (parents with a history of major depressive episodes and their children) and a multiwave longitudinal design. During…

Predictions about the role of contingency, imitation, and affect sharing in the development of social awareness were tested in infants during natural, imitative, and yoked conditions with their mothers at 5 and 13 weeks of age. Results showed that at both ages, infants of highly attuned mothers gazed, smiled, and vocalized positively more during…

Efforts to test hypotheses derived from social cognitive theory require sound measures of the theory's constructs. Because the theory is concerned with domain-specific aspects of human functioning, it raises special measurement challenges. For example, unlike traits, which can be indexed with general, all-purpose measures, social cognitive…

There is a sharp divide between quantitative and qualitative methodologies in the social sciences. We investigate an innovative way to bridge this gap that incorporates quantitative techniques into a qualitative method, the "quanti-qualitative method" (QQM). Specifically, our research utilized small survey questionnaires and experiment-like…

Objective: Many studies have confirmed the efficacy of cognitive behavioral therapy (CBT) as a treatment for depression. However, the mechanism of CBT for depression reduction is still not well understood. This study explored the mechanism of CBT from the perspective of individuals' problem-solving appraisal. Method: A one-group pretest-posttest…

The central tenet of Gottfredson and Hirschi's self-control theory is that antisocial behavior is caused by stable between-individual differences in self-control. They also argue that after early childhood, interventions aimed at reducing antisocial behavior will be unsuccessful, as one's level of self-control is resilient to such efforts. This…

Although developmental increases in the size of the position effect within a mispronunciation detection task have been interpreted as consistent with a view of the lexical restructuring process as protracted, the position effect itself might not be reliable. The current research examined the effects of position and clarity of acoustic-phonetic…

The purpose of the present study was to evaluate the regulation of goal orientations and strong "oughts" in students with learning disabilities (LD). Participants were 132 Greek students with state-identified LD using the achievement-discrepancy criterion, and 538 typical students. The first hypothesis tested was that feeling obliged to…

In recent work by Tsimpli (2003) and Tsimpli and Dimitrakopoulou (to appear) an explicit claim is made about the nature of end-state grammars in older second language (L2) learners: uninterpretable syntactic features that have not been selected during first language (L1) acquisition will not be available for L2 grammar construction. Interpretable…

Studies evaluating hypotheses about sources of differential item functioning (DIF) are classified into two categories: observational studies evaluating operational items and randomized DIF studies evaluating specially constructed items. For observational studies, advice is given for item classification, sample selection, the matching criterion,…
