The aim of this study is to investigate the mediating role of attachment styles in the relationship between childhood trauma and cognitive distortion. The sample comprised 358 (44.7% males) university students. Participants completed the Childhood Trauma Questionnaire, the Three-Dimensional Attachment Style Scale, and the Interpersonal Cognitive…

Family socioeconomic status (SES) is strongly associated with children's cognitive development, and past studies have reported socioeconomic disparities in both neurocognitive skills and brain structure across childhood. In other studies, bilingualism has been associated with cognitive advantages and differences in brain structure across the…

This exploratory Intergenerational Program (IGP) focused on reading to determine whether it affects mood and communication in older adults with mild dementia and neurocognitive deficits, and if it influences school-aged children's perceptions of older adults over time. Six older adults with cognitive-communication deficits and 12 school-aged…

Reports four experiments focusing on Piaget's claims that conservation and transitivity concepts are experienced as logically necessary truths. Two experiments examined feelings of certainty and necessity in college students presented with Piagetian tasks. Two other experiments extended these procedures to children and the issue of developmental…

Comments on Lewis's ideas about reconciling stage and specificity in neo-Piagetian theory in this issue. Focuses on whether general stages, domain specificity, and individual diversity are compatible from a nonlinear, dynamic perspective. Suggests that, by using catastrophe theory, intra- and interindividual diversity and domain specificity can be…

Discusses the role of abstraction in the development of mathematical concepts among young children. (MDH)

Investigates, using eight scenarios, children making inferences about memory from incomplete knowledge and children varying in what they judge as relevant information in their schema. Showed that older children are less likely than younger ones to invoke an inferential schema when making memory judgements. (Author/BB)

To resolve tension between general stages and conceptual specificity in neo-Piagetian theory, R. Case introduced the idea of central conceptual structures. To resolve difficulties of separating developmental level and conceptual diversity, this article reconceptualizes central conceptual structures as self-organizing systems that stabilize in…

Comments on Lewis's ideas about reconciling stage and specificity in neo-Piagetian theory in this issue. Summarizes R. Case's central conceptual structure and its relation to other neo-Piagetian theories. Notes similarities between Lewis and Piaget, suggesting that differences adhere to a limited number of general laws instead of being…

Proposes that conceptual change is constrained by the child's conceptual structures and the structures inherent in problem-solving tasks. Uses a microgenetic case study and group data to examine how interaction between strategies children bring to a task and the detailed task structure redirect children's attention and create the possibility of…

Investigated the emergence of class and propositional reasoning skills as a function of the developing ability to coordinate increasingly complex negation and affirmation operations with children from grades 1, 3, 5, and 7. Found that children's reasoning follows a logical development sequence and that different groups of items account for…

Explicit representation of relations plays some role in virtually all higher cognitive processes, but relational knowledge has seldom been investigated systematically. This paper considers how relational knowledge is involved in some tasks that have been important to cognitive development, including transitivity, the balance scale, classification…

Two experiments compared 10-year-olds' and adults' ability to choose positive and negative diagnostic tests over positive and negative nondiagnostic tests. Findings indicated that both age groups were more likely to prefer positive diagnostic tests over positive nondiagnostic tests, although only adults showed a significant preference for negative…

Investigated development of reasoning about the teaching of values in school and family contexts among 8-, 10-, and 13-year olds and college students. Found that children and young adults' reasoning is multifaceted and distinguishes between moral values that reflect justice, rights, and moral character traits and other forms of desirable…

Examined the nature of perceptual classification in children and young adults. Found that most children attend selectively to one stimulus dimension when making perceptual classification judgments. Suggests that this developmental trend does not appear to be a holistic-to-analytic shift but rather a trend toward greater consistency in following a…
