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)

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)

Approximately 150 references divided into 20 categories such as Cognition, Computers, and Curriculum. (LS)

Described and discussed is the use of discs for visual recordings to be played on television screens. (LS)

Experiments investigated whether more elements in the upper part of a visual configuration influenced newborns' preference for face-like patterns. Findings indicated that newborns preferred nonface-like stimuli with more upper part elements over nonface-like stimuli with more lower elements, but did not prefer face-like over nonface-like stimuli…

The capacity to exhibit generalized sameness-difference judgments is a hallmark of cognition that is regularly exhibited by humans. As yet, that capacity has not been well documented in New World monkeys such as the capuchin (Cebus apella). This article presents data obtained with 6 capuchin monkeys with a variety of procedures that might lead to…

In face-to-face conversation speech is perceived by ear and eye. We studied the prerequisites of audio-visual speech perception by using perceptually ambiguous sine wave replicas of natural speech as auditory stimuli. When the subjects were not aware that the auditory stimuli were speech, they showed only negligible integration of auditory and…

Two experiments examined the exploratory behaviour of flower-naive bumblebees. Bees were tested four times in a 12-arm radial arm maze in which they never received reward. Patterned and unpatterned stimuli were presented at the end of each corridor and the choices of the bees were recorded. We examined the effects of two variables, time and the…

Two studies are reported in which monolingual and bilingual children, approximately 6 years old, attempted to identify the alternative image in a reversible figure. In both studies, bilingual children were more successful than monolinguals in seeing the other meaning in the images. In the first study, there was no relation between the ability to…

This study tested whether 4-month-old infants respond primarily to objects' physical or retinal image sizes. In the study's main experiment, infants were habituated to either a 6-cm-diameter disk at a distance of 18 cm or a 10-cm disk at 50 cm. They were then given 2 test trials in which the 6- and 10-cm disks were presented side by side at a…
