The Interactive Learning Model illustrates how we process information (cognition), perform learning tasks (conation), and develop a self when performing difficult learning tasks (affectation). Individuals approach learning tasks with varying degrees of sequence, precision, technical reasoning, and confluence. These ingredients are embedded in the…

Examined infants' use of configural and physical knowledge in segregating three-dimensional adjacent displays. Found that infants do use configural knowledge: they expect similar parts to belong to same unit and dissimilar parts to belong to distinct units. Also found that physical knowledge, such as impenetrability and support, influences their…

Reed believes the proper study of psychology is not mind or stimulus-response phenomena but ways animals (including humans) encounter the world. In this view, animals are seen in environmental and evolutionary contexts; a fundamental concept is not mind or behavior but affordance or what environments offer animals; and new topics, such as…

Tested Beck's theory explaining efficacy of cognitive- behavioral therapy (CT) for depression. Involved randomly assigning 150 outpatients with major depression to a treatment focused on the behavioral activation (BA) component of CT, a treatment including BA and teaching skills to modify automatic thoughts, but excluding the components of CT…

The Holocaust has challenged students, scholars, and educators to make sense of a ghastly episode of modern times. Multidisciplinary accounts of the Holocaust should not mix history and literature domains and their symbol systems haphazardly, but should honor each domain while pursuing a fuller understanding of the experience. Docudramas confuse…

Examined 7- and 9-month-olds' ability to categorize cats and dogs as separate from one another. Found that both groups formed a cat category that included novel cats but excluded a dog and an eagle, and formed a dog category that included novel dogs and a novel cat but excluded an eagle. Results mirrored those of 3- to 4-month-olds with visual…

Twelve- and 18-month-olds played with 2 adults and 2 new toys. For a third toy, one adult left the room while the child and other adult played with it. This adult returned, looked at the 3 toys, expressed excitement, and asked "Can you give it to me?" Infants at both ages were able to do so, suggesting that 1-year-olds understand other persons as…

Presented preschoolers and first graders with 3-term inversion problems such as 3 + 2 - 2 and similar standard problems to examine whether children used the inversion principle and if use was based on qualitative identity, length, or quantity. Found that both age groups showed evidence of using inversion in a fully quantitative manner, indicating…

This study contrasted development of processing speed in 122 children between 7.5 and 11.8 years with learning disabilities and that of 206 nondisabled controls. No differences were found in relation to age in processing speed development in the two groups. Findings suggest that underlying etiologies for the normal developmental change in…

Analyzes one student's thinking using the Van Hiele levels of geometric thinking. (KHR)

Subtypes of nonsocial play were examined for matched groups of young typically developing children and children with mild developmental (cognitive) delays. Findings indicated that the nonsocial play of these children can be characterized as multidimensional in a manner similar to that of typically developing children. However, context did not…

Five experiments demonstrated that 6.5-month-olds perseverated in a violation-of-expectation task to examine reasoning about width information in containment events. After watching a familiarization event in which a ball was lowered into a wide container, infants failed to detect the violation when the same ball was lowered into a container half…

Showed English- and Japanese-speaking 3-year-olds novel objects named with either known nouns referring to items similar in shape or material and color, or novel nouns. Found that with known nouns, children attended to shape when names referred to a shape-organized category, but not when names referred to a category organized by other properties.…

Two experiments examined whether the correlation between advances on theory-of-mind and executive function tasks results from the tasks posing the same executive demands among 3- to 6- year-olds. Findings indicated that performance on the dimensional change card-sorting task (a measure of executive function) was correlated with performance on the…

Two experiments examined the influence of a delay between learning and reproducing locations on 7-, 9- and 11-year-old children's memory for location. Findings indicated that bias toward category centers when replacing objects in their original locations increased following an intervening delay, as predicted by the Category-Adjustment model, with…
