Ratings of perceptual experience on a trial-by-trial basis are increasingly used in masked priming studies to assess prime awareness. It is argued that such subjective ratings more adequately capture the content of phenomenal consciousness compared to the standard objective psychophysical measures obtained in a session after the priming…

Bhatt and Quinn (2011) present a compelling case that human learning is "early" in two very different, but interacting, senses. Learning is "developmentally" early in that even infants show strikingly robust adaptation to the structures present in their world. Learning is also early in an information processing sense because infants adapt their…

Purpose: The purpose of this study was to examine children's head orientation relative to the arrival angle of competing signals and the sound source of interest in actual school settings. These data were gathered to provide information relative to the potential for directional benefit. Method: Forty children, 4-17 years of age, with and without…

Gottlieb promoted the value of a developmental psychobiological systems approach to the study of human development. This approach recognizes the importance of comparative, animal-based research to advancing our understanding of the complexities and dynamics of the process of development. The major contribution of animal developmental studies is…

The short-term reliability and long-term stability of visual habituation and dishabituation in infancy were assessed in a sample of 186 infants from four age groups (3-, 4-, 7- and 9-month-olds) seen for two within-age sessions, and in a sample of 69 infants seen longitudinally at 3, 4, 7, and 9 months of age.

This paper offers a model of visual functioning focusing on three factors: (1) visual capacity, (2) visual processing, and (3) visual attention. Practical implications of visual therapy are considered, and intervention strategies with children with impaired visual functioning are suggested. (Author/DB)

Examined in two studies the moderating effect of perceptual load on visual selective attention. Found that children's performance was as efficient as adults' under conditions of high but not low loads, suggesting that early selection engages rapidly maturing neural systems and late selection engages later-maturing systems. The onset of early…

Describes two experiments that examined the effects of quantity and depth of processing on elementary school children's time perception. (HOD)

Examined the role of same-sex peer interactions in influencing early school competence and the degree to which effortful control (EC) moderated these relations. Results indicated that EC, measured at the end of the Fall semester, moderated the relations of children's same-sex play to their school competence, measured at the end of the following…

Children with mental retardation are particularly prone to failure on relational tasks such as oddity and match-to-sample, suggesting a differential sensitivity to relational information. This paper reports on several studies in which characteristics of stimulus arrays were enhanced. Results demonstrated the theoretical and practical significance…

Investigates age differences in selective attention in a coded visual search task where subjects were given different types of information about target location before trial onset. (Author/SS)

Discusses changes occurring in two-, four-, and six-month-old infants' visual attention span, through a series of experiments examining their ability to orient to peripheral visual stimuli. The results obtained were consistent with the hypothesis that infants get faster with age in shifting attention to a spatial location. (AA)
