Four experiments examined whether infants' use of task-relevant information in an action task could be facilitated by visual experience in the laboratory. Twelve- but not 9-month-old infants spontaneously used height information and chose an appropriate (taller) cover in search of a hidden tall toy. After watching examples of covering events in a…

This investigation examined whether infants display "boundary extension"--a tendency to remember more of a visual scene than was presented. Three- to 7-month-olds were familiarized with a photograph of a visual scene, and tested with wide-angle versus close-up views of the scene. Infants preferred the close-up, indicating that they perceived the…

Background: Trials in developing countries suggest that improving young children's diet may benefit cognitive development. Whether dietary composition influences young children's cognition in developed countries is unclear. Although many studies have examined the relation between type of milk received in infancy and subsequent cognition, there has…

This paper discusses recent studies of the adult visual evoked potential (VEP) which have indicated that specific components of the complex waveform obtained are related to the three basic color processes, and that these components interact in ways that seem to agree with opponent-colors phenomena. The components identified as being related to the…

Examines the ability of infants ranging in age from 21 to 44 hours old to discriminate among visual stimulus arrays. Infants were able to discriminate between small sets of dots (two to three dots) but not between larger sets (four to six). (Author/MP)

Examined acuity thresholds for 1- and 2-month-old infants by presenting square wave gratings in a preference paradigm at four viewing distances. (Author/JMB)

Six experiments assessed 4- to 8-month-old infants' reactions to probable and improbable orientation positions following invisible transformations from an original orientation. Availability of orientation cues, objects' path of motion, and amount of invisible spatial transformation were varied. Results indicated that infants as young as 4 months…

Assessed 14-week-olds' attention to green or red target objects moving in a field of distracting objects that varied in color. Found that infants' detection of green moving targets was masked in the presence of mixed red and green objects. Masking was not observed for red targets or for green targets in a field of green objects. (BC)

Results indicated that habituated 20-week-olds showed evidence of color constancy, but habituated 9-week-olds did not. The younger subjects responded with increased attention to simulated changes either of the illuminant or of surface reflectance, whereas older subjects responded with increased attention only to simulated changes of surface…

Infants were habituated to reversible and nonreversible pictures of faces. The reversible picture depicted a different face when inverted 180 degrees. For the reversible picture, the infants devoted more visual attention to the inverted picture than to the original picture. (BC)

A study involving 90 children (50 preterm and 40 full-term) found continuity in visual recognition memory from early infancy (7 months) to later childhood (11 years), even when other measures of memory at 11 years were controlled. Implications for the study of other types of infant memory are discussed. (SLD)

Examined infants' categorization using object manipulation tasks that involved objects that were models of animals, vehicles, or furniture. Objects were normal, had anomalous moving parts (such as a dog with wheels), or had different textures. Found that 14- to 22-month olds attended to the parts and structural configuration of objects, but not to…

Thirty 12- to 13-month-olds were tested to determine whether they could use the self as an analogy for understanding others' looking. Using a procedure similar to Brooks and Meltzoff (2002), we examined gaze-following when the adult's view of a target was occluded by a blindfold (blindfold without training). Some infants received experience with…

The perception of colour in an embedded field is affected by the surround colour. This phenomenon is known as chromatic induction. In the present study we investigated whether the colour perception by infants aged 5-7 months could be affected by the surround colour. In Experiments 1 and 2 each stimulus was composed of an array of six squares in…
