Assessed the relative difficulty in the utilization of oddity and matching response strategies in 144 children, ages 5-13 years. A model of matching and oddity problem-solving is presented based on the data collected. (Author/ED)

Both observational techniques indicated similar findings in age-related behavior changes. Continuous-recording yielded a more molecular analysis and was concluded to be more desirable for collecting naturalistic observation data. (ST)

Explores a methodology for determining if young children's responses to a specific training procedure could be identified as "learning" or "development." Twelve nonconserving kindergartners were administered a standard conservation of substance task, and three variations of the same task. (CM)

This study was designed to determine if: a) attentuation of irrelevant information on a selective attention task would result in increased selective attention, and b) a developmental increase in selective attention would be replicated with the use of a different procedure of data analysis than has been used previously.

Employed regression analysis to determine the association between multiplicative classification and inductive reasoning. Subjects were 103 fourth grade children. (SDH)

A total of 60 kindergarten and first- and second-grade girls were presented with three tasks: concept-shift, sort, and hierarchization. Without exception, children who failed a task also failed the higher-order task(s), and children who passed a task also passed the lower-order task(s). Implications in relation to Piaget's theory of development of…
