Absolute judgment may be characterized as a special case of paired-associate learning in which the stimuli and responses are ordered, and responses are assigned to stimuli in serial order. (Authors)

Results of this study indicated that the frequency of an auditory stimulus is a dimension to which infants differentially respond in terms of response rate and acoustic characteristics of their vocalizations. (Authors)

Primary purpose of this study was to examine the effect of observed verbal reward to a model on an observer's performance while controlling for the presentation of verbal consequences to the critical responses of the model. (Author)

Structural approaches to musical meaning are discussed, and the educator's responsibilities in helping students develop aethetic sensitivity are described. (DB)

Some infants, soon after birth, are capable of storing visual information as reflected in their ability to detect and respond to change in the immediate environment. (Author)

Implications of the findings for support of trace modality hypotheses are discussed. (MB)

Testing Pollack's hypothesis that decreases in effective contour contrast (resulting from a decrease in receptor sensitivity with age or from a change in actual stimulus contrast) lead to decreases in illusion magnitude. Conclusions are questioned by Sjostrom and Pollack (PS 501 740). (Author/MB)

Glanzer and Clark's verbal loop hypothesis" appeared to be contradicted by these data. (Author)

Results demonstrate that 12 - 15 - week-old male infants smile to nonsocial stimuli, and offers support for the recognition hypothesis of infant smiling. (Authors/MB)
