In three experiments, 5-month-old infants discriminated between a perfectly contingent live display of their own leg motion and a noncontingent display of self or a peer. They showed this discrimination by preferential fixation of the noncontingent display. (Author/NH)

Tested and confirmed, in three experiments, the hypothesis that children's interpretation of pictorial conventions and of the expression "look like" may increase their tendency toward intellectual realism. That is, a tendency to respond to requests for perceptual reports by indicating what is known about an object or array, rather than…

Three experiments involving institutionalized mentally retarded persons revealed that the antecedent stimulus manipulation (i.e., hiding the candy or the kitty) was critical to establishing correct performance, while manipulation of the consequent stimuli afffected performance slightly. Findings had implications for reinforcement conditions. (CL)

Twenty profoundly retarded children (mean chronological age 14 years) were observed while playing with special toys which emitted stimuli when appropriately operated. They were also observed with the toys when the stimuli were unavailable. Ss interacted significantly more with the experimental toys than control toys and engaged in significantly…

Differential looking and manipulation were assessed in 44 six-month-old infants who were presented with familiar and novel visual stimuli. The infants looked at the novel stimuli longer. (ST)

Data from an article published by other authors is reanalyzed to demonstrate how contour density can account for the infant fixation preferences reported. (ST)

Twenty subjects between the ages of six and 12 years with a diagnosis of seizure disorder were used to investigate the relationship between therapeutically applied tactile stimulation and the incidence of seizures and changes in the electrical activity as measured by the EEG. (Editors/JA)

The form of the cardiac reaction to the novel stimulus was regarded as support for an attentional interpretation of cardiac deceleration. (Author)

This study was planned to explore the effect of two typographic factors on the perceived appeal of a printed page: typeface and leading." (Author)

The research reported here is based on a thesis submitted by the author to Yale University in partial fulfillment of requirements for the Ph.D. degree. (MH)

For infants from 3 to 6 months old, novel stimuli commanded significantly more attention than familiar stimuli on both immediate and delayed tests of stimulus recognition. (MH)
