A modal model of information processing was defined, and nine tasks that could be completed by persons with mental retardation were developed to operationalize the model. Results showed that individual differences in higher mental processes are highly dependent on basic cognitive abilities and can be predicted from them. (Author/JDD)

Twenty-two college students from each of three different epistemological groups--dualistic, multiplistic, and relativistic--completed both a syllogism and ink blot problem-solving task. Findings indicated that the three epistemological groups reliably differed in how they mentally organized the ink blot stimuli but not the syllogism problems.…

This study of the choice behavior of 14 adults with severe disabilities in residential programs found that 24 staff members correctly predicted the individuals' choices 78% of the time, when compared to choices made by the individuals themselves. (Author/DB)

Visual, auditory, and bimodal event-related potentials were recorded from 50 males, and lateral asymmetry indices were derived. Eleven psychometric tests of different cognitive attributes were also administered to them. This area of research has been labeled aptitude-treatment-interaction (ATI). The emphasis of ATI research is on identification of…

Inherent limitations on the feasibility of experimentation have made it difficult for investigators to formulate an adequate understanding of individuality as a psychological phenomenon. Recently, Fiske (1979) and Sontag (1971) have suggested that application of a longitudinal or developmental strategy might be of some use in remedying this…

An overview of theory and research in memory as it relates to developmental differences is offered in this paper, which is intended to provide background information for the staff of the Skills Essential to Learning Television Project (a multi-level series of video and print resources for classroom use). A model for viewing information processing…

Examined how an unstable rather than stable view of dispositions--that is, personality traits and abilities--affected the motivational consequences of 7- and 8-year-old children's success and failure experiences, and their self-confidence and impressions of other persons. (SKC)

The persistence of individual differences in phonological development of 10 normally developing children observed at age one and again at age three was studied. The children differed considerably in rate of vocabulary acquisition and relative phonological maturity and also in their general approach to learning. (Author/JDD)

A path model of genetic and shared family environmental transmission was fitted to general cognitive ability data from 1-, 2-, 3-, and 4-year-old adopted and nonadopted children and their parents to assess the etiology of longitudinal stability from infancy to early childhood. (HOD)

Experiment 1 examined the position that mirror-image confusions reflect an inability among three- to five-year-olds to determine whether their performance level differences reflect differences among nonreaders already attending and those not yet attending to reading cues. Experiment 2 examined the Experiment 1 four- and five-year-olds, identified…

Compared 32 childfree with 20 child-anticipated couples. No differences were found between the groups on marital adjustment, marital type, or sex role identification, although a trend was found suggesting that childfree women tended to view themselves as less sex-typed than child-anticipated women. (Author/NRB)

Study of children aged 21 to 31 months tentatively concludes: (1)behavioral tendency to be inhibited or uninhibited with unfamiliar people or during unfamiliar events is moderately stable across time and context; and (2)moderately negative relationship exists between behavioral inhibition and heart rate variability, and positive relationship…

Three studies investigated: the effect of parent involvement on the exploratory behaviors of children rated as high-, moderate-, or low-explorers; whether maternal presence increased the exploration of low-exploratory children, decreased the exploration of high-exploratory children, or both; and whether maternal presence or mother/child…

Combinatorial abilities in language and elicited symbolic play were compared in a longitudinal study of 30 children at 20 and 28 months. In addition, multivariate analyses were used to assess the stability of individual differences. Generally, different symbolic play variables contributed unique explained variance to different language variables.…

Twenty-five infants were tested every two weeks on the AB Object Permanence Task, from the time they first reached for a hidden object until they were 12 months old. Results indicate that the AB provides an index of the ability to carry out an intention based on stored information despite a conflicting habitual tendency. (Author/RH)
