Investigates the responsiveness of 14- and 20-week-old infants to binocular information using a stereoscopic shadow caster showing an object approaching on a collision course. (Author/SS)

Three experiments investigated four-month-old infants' capacity to perceive bimodally specified events by detecting the temporal synchrony of sound bursts with the visable impacts of surfaces. (Author/SS)

Examined effects on duration of gaze of infant- and adult-directed (ID and AD) speech signalling presentation of adult faces. Found that, when ID speech segments signaled presentation of a smiling, sad, fearful, or angry face, significant and comparable conditioning occurred with the smiling and sad faces, whereas nonsignificant and more variable…

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…

Describes 4 experiments examining 10-month-old infants' causal event perception. Results from all experiments indicated that infants perceived causality of simple events by associating a specific agent with a causal action. These results provide more support for an information-processing view of causal perception than for a view that explains…

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…

Two experiments tested the DeLoache, Pierroutsakos, Uttal, Rosengren, and Gottlieb (1998) claim that 9-month-old infants attempt to grasp objects depicted in photographs. In Experiment 1, 9-month-olds viewed an object, a photograph of the object, and 2 flat, nonpictorial displays. On average, they reached for the photograph and nonpictorial…

Infants' visual perception of number change was investigated in three studies. These studies focused on infants' perception of events in which the total number of objects in a small group was changed through addition of another object. Involving 60 infants 5 months of age, Study I attempted to determine whether subjects perceived the properties in…

In this study of the visual placing response (an extension of the paws or arms on approach to a visual surface), infants extended their arms almost as much to a gray surface as to a patterned one. (Author/CS)

Subjects of this study were 19- and 23-week-old infants. Results showed that the older infants demonstrated differential attention to novel over familiar stimuli during recognition tests. An examination of their responsiveness during familiarization presentations indicated differing trends of looking activity. (Author/CS)

This paper deals with research on the development of infants' ability to perceive invariant features of things and the relation of objects to both the spatial layout of the infants' environment and to themselves. Basic assumptions regarding the perception of invariance are discussed and a theoretical view of the role of motion in the development…

A looming paradigm was used to determine what depth information infants process in addition to that provided by the expansion of a single, closed contour of an object. A total of 18 male and 15 female infants aged 22-48 days watched a film in which the circular elements and inter-element spaces of the projected image alternately expanded and…

Results showed that 2- and 3-dimensional forms affected 4- and 8-week-old infant visual behavior differently. (Author/JMB)

This study was designed to investigate the development of the visual placing response in infants, as well as the visual mediation of the response and texture factors that influence this response during its development. The response was associated with age and apparently developed in two phases. (Author/DB)

Results of two studies were consistent with the view that 3-month-old infants perceive movement in depth during their own movement. They can move to avoid a surface just prior to contacting it. (Author/RH)
