Children from grades 1, 3 and 5 classified and later recalled 24 pictorial items. It was found that classification, recall and clustering scores increase with age and vary as a function of item category. (GO)

The possible effect of experimenter expectancy in number conservation task experiments was explored. (JMB)

Examined how college-age adults and 8-, 11-, and 13-year-olds retrieve semantic information from long-term memory. Closely comparable results were obtained across ages. This developmental similarity is discussed in relation to developmental differences in the use of semantic information in other cognitive tasks. (JMB)

Boys, ages 6, 8, and 10, were classified with regard to conceptual tempo and were presented with cartoon stimuli varying in cognitive complexity and level of affectivity. The results indicate that reflective subjects generally displayed the highest comprehension scores while impulsive subjects displayed the greatest spontaneous mirth. (JMB)

Two experiments investigated the role of kindergarten and elementary school children's spontaneous cognitive sets in pictorial discrimination learning.

A necessary condition for studying cognitive images of environments is an appropriate method to define and measure these. Using a sample of students in Bristol, the Repertory Grid method was used to measure images of the retailing environment. The empirical results are discussed and possible future research is outlined.
