Presolution reversal prevented or significantly retarded learning in kindergarten and first-grade children but did not hinder learning in fifth-grade children. (Authors)

Major finding of this study is that relative cue similarity can be used as a definition of dimensional dominance and that it predicts both initial learning and shift behavior for normal first- and third-grade children. (Author)

Children's performance on multidimensional classification tasks was examined in two experiments. In Experiment 1, preschool, first-, and third-grade children were shown a standard stimulus and were then asked to judge whether several comparison stimuli were the same as or different from the standard. Comparison stimuli differed from the standard…

Experiment was designed to examine the relationship between intelligence, stimulus meaningfulness and stimulus selection. (Authors)

It was concluded that previous explanations of visual exploration or stimulus preference have been oversimplified, and studies on the whole have failed to take into account a crucial interaction between sex and age variables. (Authors)

This study was designed to determine if the failure of previous investigations to find habituation and response to novelty in infants younger than 2 months of age was because the stimuli used were too complex or because a constant number of trials rather than an individual criterion of habituation was used. A total of 24 infants between 5 and 6…
