Color and form preferences of kindergarten, first and third grade Ss were tested using standard two-dimensional geometric forms. (Author)

Results lend partial support to the proposition that the effectiveness of a particular rehearsal strategy depends on the degree to which it provides a discriminative cue for the materials on hand: With homonym pairs, imagery constituted such a discriminative cue, while vocalization did not; with synonym pairs, the converse was true.

Attempted to maximize the efficacy of time-delay discrimination training of 16 preschoolers. No indications were found of effects of precision response pretraining on the outcome of time delay of static cues. Transfer and lack of transfer of stimulus control were associated with nonshifts and shifts of response loci, respectively. (RH)

Used shift-rate recovery method in three experiments to examine extent to which 6-month-olds find perceptual cues such as density and length useful in discrimination of linearly arranged sets of large numbers of objects. Found that infants can discriminate between large number sets by relying on absolute cues such as density and on relative cues…

A total of 128 first- and second-graders participated in two sets of shift problems: (1) four extra-dimensional shifts; and (2) shift problems with two types of cue-reinforcement conditions (same and reversal). (ED)

Three experiments investigated 4-, 6-, and 8-month-olds' perception of the audible, visible, and combined attributes of bimodally specified syllables. Results suggested that at 4 months, infants attended primarily to the featural information, at 6 months primarily to the asynchrony, and at 8 months to both features independently. (Author/KB)
