Previous findings of a developmental trend from holistic to analytic modes of processing are subject to two possible interpretations: the ability to analyze according to dimensions increases with age, or a production deficiency for the strategy of analyzing decreases with age. This study tests these interpretations through an examination of…

Four experiments investigated the development of visuomotor control in sequential pointing in tasks varying in difficulty among 6- to 10-year-olds and adults. Comparisons across difficulty levels and ages suggest that motor development is not a uniform fine-tuning of stable strategies. Findings raise argument for stage characteristics of…

Describes two experiments that examined the conditions determining age changes in novelty preferences of children. (HOD)

Two experiments examined developmental changes in reasoning about intensive quantities--predicting mixture intensity of pairs of liquids with different intensities of red color. Results showed that cognitive averaging in this domain developed late and slowly. Predominating up to 12 years was an extensivity bias, a strong tendency to use rules that…

Adults' ability to track a moving target was examined in two experiments in order to compare their performance with that of very young infants. Results indicated that (1) adults'"overshoot" errors resembled those reported for young infants; and (2) adults had problems tracking a moving target which unexpectedly changed direction. (Author/DB)
