Reflective subjects generated characteristically different and more efficient hypothesis-testing strategies than impulsive subjects. (Author)

This study is consistent with a model of semantic memory that assumes that the memory store is organized primarily into noun categories, and that the process of retrieving information from this store consists of entering the appropriate category as a first step. (Authors)

Given a chance to eat the candy or drink the juice in this study, the 5-year-olds, 7-year-olds and young adults failed to conserve and made choices based on what they said was appearance of greater quantity rather than upon the already established equivalencies. (Authors/CB)

Children who recognize a compensatory relationship between height-width dimensions are more susceptible to conservation training than children who do not recognize this relationship. (Authors)

Results confirm the hypothesis that identity and equivalence conservation require different mental processes. (Authors/MB)

It is evident from this task that preschool children can remember simple pictures as well as their names, that either pictorial or verbal codes can mediate memory of either pictures or words in accordance with task demands, and that same-different judgments tend to be faster to pictures than to words.

Testing Pollack's hypothesis that decreases in effective contour contrast (resulting from a decrease in receptor sensitivity with age or from a change in actual stimulus contrast) lead to decreases in illusion magnitude. Conclusions are questioned by Sjostrom and Pollack (PS 501 740). (Author/MB)

Author challenges the findings of Helene Borke who presented evidence interpreted as demonstrating that children as young as 3 years of age were able to successfully abandon their own egocentric perspectives and adopt the points of view of others. Rejoinder by Borke is presented in PS 502 130. (MB)

It was shown that hierarchies change with development and that relative salience of a dimension is negatively associated with both reaction time of choice and number of errors on the identity task. (Authors)
