Can infants use interposition and line junction cues to infer three-dimensional (3D) structure? Previous work has shown that in a task that required 4-month-olds to discriminate between static two-dimensional (2D) pictures of possible and impossible cubes, infants exhibited a spontaneous preference for displays of the impossible cube but left open…

Attempts to determine whether the stimulus dimension to which infants respond is different in fixed-trial and infant-control methodologies. Infants 10 weeks of age were shown four facelike patterns differing along two dimensions: number of elements and extent to which elements were organized to resemble the human face. (Author/RH)

Four-month-old infants' stimulus preferences were assessed using an operant paradigm with mobile reinforcers of different colors (blue, green). (Author/MP)

An investigation of 4-month-old children's attention responses to pattern dimensions and orientations by comparing the duration of an infant's fixation to changes in the orientation and structural arrangement of a previously exposed pattern. (ED)

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)

Preverbal infants can represent the causal structure of events, including distinguishing the agentive and receptive roles and categorizing entities according to stable causal dispositions. This study investigated how infants combine these 2 kinds of causal inference. In Experiments 1 and 2, 9.5-month-olds used the position of a human hand or a…

Two experiments investigated whether 5-month olds would look longer at rotating "drawbridge" appearing to violate physical laws because they knew it was causally impossible. Findings indicated that infants' longer gaze at 180-degree rotations was due to simple perceptual preference for more motion, challenging Baillargeon's (1987) claim…

Three experiments examined infants' processing of three-dimensional (3D) information in static images. Results indicated that 3-month olds are sensitive to 3D cues in static images. However, discrepancies based on these cues may not engage infants' attention like those based on fundamental features. (Author)

Newborns were presented with a tape-recorded rattle sound through a single loudspeaker, through two loudspeakers with one onset leading the other by seven msecs., and through two loudspeakers simultaneously. Newborns turned toward the single source sound, but not toward either of the dual source sounds. (Author/RH)

Investigates intersensory interaction between auditory and visual stimulation in newborn infants. Following auditory stimulation, newborns' visual preferences for light patches of different intensity were examined. Results indicate that newborns attend to quantitative variations in stimulation and that these variations reflect both the objective…

Compared food texture preferences during infancy and toddlerhood. Found that infants displayed more negative expressions and head and body movements in response to complex textures than to simple textures. Toddlers displayed more positive head and body movements and more eagerness in response to complex than to simple textures. Experience with…

This study examined behavioral correlates of the rapid central nervous system changes occurring in the first 4 months of life. It was hypothesized that during the early months of infancy, visual preference would occur as a function of quantitative dimensions of the stimuli (size) which could be mediated at a subcortical level. It was further…

Studied feeding-related arousal effects on a visual recognition paired-comparison task at newborn, 1, and 4 months of age. Found that newborns and 1-month olds shifted from a familiarity preference before feeding to a novelty preference after feeding. Control-group testing confirmed that shift was not due to increased stimulus exposure. By 4…

This study examines serial habituation in a sample of 54 infants aged 2, 3, and 4 months to determine whether age changes are partially a function of different "strategies" rather than simply different rates of habituation. The serial habituation hypothesis proposes that attention and habituation of attention proceed in order of the relative…
