Two studies examined associations between theory of mind performance and counterfactual thinking using both antecedent and consequent counterfactual tasks. Moreover, the studies examined children's abilities to generate different types of counterfactual statements in terms of direction and structure. Participants were 3-, 4-, and 5-year-old…

Two experiments examined children's early judgments about numerical relations. Found that children as young as three years old are already adept at reasoning about relations between sets, independently of their ability to form numerical representations. Results support the existence of protoquantitative schemas, or ways of thinking about relations…

Hypothesizes that horizontal decalage, or the mastery of one task but not another formally similar to it, is an expected outgrowth of Piagetian theory. (MB)

In this article, the author gives a general introduction of a few ideas on cognitive development in children. In the first part, he deals with the topic of development, a process which concerns the totality of the structures of knowledge. He reviews the stages of development of operational structures, distinguishes four main stages of development,…

This research contrasts the learning effects of an affective dimension of meaningfulness with the word-quality of consonant-vowel-consonant trigrams. Subject rated trigrams for both "association value"--having word-quality versus lacking word-quality--and "reinforcement value"--liking versus disliking the trigram regardless of word quality. Paired…

Investigates the comparative effectiveness of two teaching strategies, large-group and individual/small group singing activities, on kindergartners' developmental music aptitude. Examines improvements in children's singing and musical aptitude in order to ascertain length of time and types of instruction necessary to affect improvement. (MJP)

Piaget's model of children's conceptual learning and development was compared with Klausmeier's Conceptual Learning and Development (CLD) model in a longitudinal study. The CLD model suggests four successive levels of concept learning: (1) concrete--recognizing an object which has been encountered previously; (2) identity--recognizing a known…

The Conceptual Learning and Development (CLD) Model specifies four levels of concept attainment (concrete, identity, classificatory, and formal) and three uses of concepts (problem solving, subordinate-supraordinate, and principles). Longitudinal and cross-sectional studies of concept attainment may be conducted. The results of this study of 300…
