Three models representing different relations between intellectual ability, metacognitive skills, and learning were compared. The conditions under which each of these models holds were investigated, on the basis of the threshold of problematicity theory [Elshout, J. J. (1987). Problem solving and education. In E. De Corte, H. Lodewijks, R.…

The current study explored body image self-discrepancy as moderator and social comparison as mediator in the effects on women from thin-ideal images in the media. Female undergraduates (N = 112) with high and low body image self-discrepancy were exposed to advertisements either with thin women (thin ideal) or without thin women…

According to the hedonic treadmill model, good and bad events temporarily affect happiness, but people quickly adapt back to hedonic neutrality. The theory, which has gained widespread acceptance in recent years, implies that individual and societal efforts to increase happiness are doomed to failure. The recent empirical work outlined here…

This paper reports the findings of a longitudinal study of the literacy teaching of two teachers who were involved in a large-scale government initiative to change the way literacy is taught. These two teachers were identified at the outset of the study as being very different in ways in which they thought about the teaching of reading and…

Evoked potential studies have demonstrated that musicians have the ability to distinguish musical sounds preattentively and automatically at the temporal, spectral, and spatial levels in more detail. It is however not known whether there is a difference in the early processes of auditory data processing of musicians. The most emphasized and…

Prosodic, or expressive, reading is considered to be one of the essential features of the achievement of reading fluency. The purpose of this study was to determine (a) the degree to which the prosody of syntactically complex sentences varied as a function of reading speed and accuracy and (b) the role that reading prosody might play in mediating…

To examine effects of input and learner characteristics on morphology acquisition, 60 adult English speakers learned to inflect masculine and feminine Russian nouns in nominative, dative, and genitive cases. By varying training vocabulary size (i.e., type variability), holding constant the number of learning trials, we tested whether learners…

Seventy 15-month-old children were observed during 90 minutes of free play with their peers in childcare centers. The study aimed to describe individual differences in the children's contacts with peers and to explain the individual differences in relation to: (1) child temperament, (2) the quality of parental behavior toward the child and (3) the…

Individual differences may partly explain how students react to potentially offensive sexual behaviors from peers. This study focused on situational and personal characteristics that may make such behaviors more or less upsetting. Six hundred and thirty two Quebecois high-school students in Grades 8-11 completed questionnaires regarding their…

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…

The assessment of individual differences in facial expression recognition is normally required to address two major issues: (1) high agreement level (ceiling effect) and (2) differential difficulty levels across emotions. We propose a new assessment method designed to quantify individual differences in the recognition of the six basic emotions,…

This contribution offers an overview of two studies testing two attachment theoretical correspondence hypotheses in the prediction of individual differences in young children's God concepts. The correspondence hypothesis supposes that people's view on God parallels their images of their early caregiver-child relationship. The revised…

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…

The authors investigated the relationships between cognitive, motivational, and emotional variables across Hispanic and White students to predict mathematics performance. A theoretically based structural model fit a total sample of 666 4th- to 10th-grade students well, supporting that self-efficacy, sources of self-efficacy, and emotional feedback…

This paper presents a lifespan perspective of sexuality issues for individuals with developmental disabilities. Individuals with developmental disabilities are human beings who have historically been denied the right to express their sexuality or engage in sexual relationships due to misconceptions or negative attitudes. Using a hypothetical case…
