The Effects of Mode of Presentation and Number of Categories on 4-Year-Olds' Proportion Estimates.
Widom, Cathy Spatz; Ginsburg, Herbert
Two experiments investigate the effects of mode of presentation and number of categories on 4-year-olds' proportion estimates. Experiment I compares simultaneous and successive presentations of proportion problems using two categories of elements. The subjects were 40 children chosen randomly and tested individually. Four problems were presented simultaneously to one half of the children, and given successively to the other. The results indicate that 4-year-olds are fairly accurate in their estimates and are able consistently to discriminate proportions differing by .20, but not by .10. The results replicate fairly well an earlier study by Ginsburg (1967). There were no significant differences in estimates of proportion as a result of mode of presentation. Experiment II studied the effects of three categories of elements presented simultaneously. The subjects were thirteen 4-year-olds chosen randomly. The results show that estimates are different from and poorer than those of two category problems, and the children performed approximately at chance level. (JF)
