Recognition by infants, 13 and 22 weeks old, was tested by pairing novel stimuli with the familiarization stimulus at different points in an experimental session. Younger subjects showed no recognition of either two- or three- dimensional stimuli. Older subjects demonstrated more recognition in the three-dimensional condition. (MS)

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. (Author/JH)

The ability of 3-month-old infants to discriminate novel components of a pre-familiarized stimulus was assessed using an operant paradigm. Subjects were 20 infants; adult judgments were taken from 15 college students. (Author/JH)

Author claims that Piaget's account of the construction of reality needs modification and a shift in emphasis. (Author/MB)

Study attempted to determine the viability of optimal level theory as it pertains to infant perceptual and cognitive development. (Authors)

Paper presented at the Merrill-Palmer Conference on Research and Teaching of Infant Development, February 13-15, 1970. (JE)

Traditional developmental protocols based on neurological or sensorimotor models frequently underestimate the cognitive status of physically handicapped infants. A critical review of current clinical practices in the area of infant assessment is followed by a discussion of an alternative approach, a perceptual-cognitive approach, and the…

One- and two-month-old infants were shown schematic drawings of a human face with features arranged (1) naturally, (2) symmetrically but scrambled, and (3) asymmetrically and scrambled. Two-month-olds discriminated among all arangements and preferred the natural arrangement; one-month-olds showed no discrimination or preference. (Author/DB)

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)

Two experiments were conducted to examine whether gross perceptual similarity (shape similarity) and basic conceptual similarity (label similarity) are processed by very young children and influence preferences for novel stimuli. The 88 subjects were 12 to 38 months of age. (MP)

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…

Results indicate that seven-month-old infants are sensitive to the depth cues of linear perspective and texture gradients. Self-produced locomotor experience is not necessary for the development of sensitivity to static-monocular depth information. (RJC)

Investigated infants' integration of visual information across space and time. In four experiments, infants aged 12 months and 6 months viewed objects after watching light trace similar and dissimilar shapes. Infants looked longer at novel shapes, although six-month-olds did not recognize figures taking more than 10 seconds to trace. One-year-old…
