Four experiments were conducted to investigate the extent to which infants of different ages respond to facelike drawings on the basis of stimulus complexity and/or resemblance to the human face. Infants' responses to stimulus patterns were assessed using the corneal reflection technique developed by Robert Trantz. In the first two experiments,…

Three groups of Nigerian high school and college students were tested for response to four pictorial depth cues. Students had more difficulty with cues concerning the relative size of objects and the foreshortening of straight lines than with cues involving overlap of lines and distortion of the angles between lines.

A series of experiments is described whose aim was to define certain of the effective dimensions of stimulation in the newborn's visual environment. (Author/JMB)

Human infants' discrimination of changes in internal and external elements of compound visual patterns was investigated in four experiments employing a familiarization-novelty paradigm in which visual reinforcing patterns were presented contingent upon rate of high-amplitude nonnutritive sucking.

Stabilization of the retinal image of the boundary between a pair of red/green or yellow/blue stripes, but not their outer edges, results in the entire region being perceived simultaneously as both red/green or yellow/blue. This suggests that the percepts of reddish-green/yellowish-blue apparently are possible in corticocortical color vision…

Eight sets of paired auditory and visual stimuli were constructed. Each member of the auditory pair was matched by one member of the visual pair (e.g., ascending "tone/up arrow"; descending "tone/down arrow"). Sixty-one infants with a mean age of 11.4 months were presented matching and unmatching stimuli; total fixation time…

The effectiveness of motion parallax for relative and absolute distance judgments was studied using second-, fourth-, and sixth-grade children and college students. (JMB)

Tested whether a verbal description given before or after presentation of a picture effected visual processing and/or memory. (SB)

Three studies investigated whether eye gaze cueing in 4-month-old infants is the result of a domain-specific module or reflects the activity of domain-general processes. In two of three experiments, infants perceived apparent motion of the pupils, and this directly elicited saccades, but only when this motion was preceded by a period of direct…

Used a habituation-dishabituation procedure to test ability of 4-, 5-, and 7-month-olds to differentiate between a subjective ellipse and a nonsubjective pattern that were constructed by displacing the inducing elements of the illusory figure. Found that even 4-month-olds discriminated between the subjective ellipse and nonillusory display. This…

The capacity of six-month-old infants to maintain information in working memory for several seconds was studied using two versions of an oculomotor delayed response task. The results indicated that infants maintained information about stimulus locations in working memory for three to five seconds. (MDM)

Explored the role of motion versus shape in children's categorization of animal and non-animal kinds. Found that 4-year olds significantly used motion cues over shape cues to categorize objects. Seven-year olds and adults tended to use motion more than shape to categorize animals but not geometric figures. Findings support view that children are…

Vidic and Haaf (2004) questioned the idea that infants use head information to categorize cats as distinct from dogs (Quinn & Eimas, 1996) and argued instead that the torso region is important. However, only null results were observed in the critical test comparisons between modified and unmodified stimuli. In addition, a priori preferences for…

Why are human observers particularly sensitive to human movement? Seven experiments examined the roles of visual experience and motor processes in human movement perception by comparing visual sensitivities to point-light displays of familiar, unusual, and impossible gaits across gait-speed and identity discrimination tasks. In both tasks, visual…
