Describes an in-depth, comprehensive method that enables students to understand the basic concepts of visual perception. (JRH)

This article reviews the theoretical and research literature on vision stimulation and vision training of children with severe irreversible visual impairments. It recommends early stimulation to prevent visual deprivation, use of operant conditioning, and the presentation of highly contrasting stimuli to stimulate visual awareness in children with…

The basis for the category specific living things advantage in object recognition (i.e., faster and more accurate identification of living compared to nonliving things) was investigated in two experiments. It was hypothesised that the global shape of living things on average provides more information about their basic level identity than the…

This article examines how the human visual system represents the shapes of 3-dimensional (3D) objects. One long-standing hypothesis is that object shapes are represented in terms of volumetric component parts and their spatial configuration. This hypothesis is examined in 3 experiments using a whole-part matching paradigm in which participants…

Observers often miss the 2nd of 2 visual targets (first target [T1] and second target [T2]) when these targets are presented closely in time; the attentional blink (AB). The authors hypothesized that the AB occurs because the attentional response to T2 is delayed by T1 processing, causing T2 to lose a competition for attention to the item that…

This experiment assesses spatial and nonspatial relational memory in freely moving 9-mo-old and adult (11-13-yr-old) macaque monkeys ("Macaca mulatta"). We tested the use of proximal landmarks, two different objects placed at the center of an open-field arena, as conditional cues allowing monkeys to predict the location of food rewards hidden in…

Investigates the different levels in the visual system at which laterality effects may be elicited in children and adults in five different experiments. (LLK)

Experiment 1 supported in part by National Institute of Mental Health (NIMH) Research Grant M2232. Experiment 2 submitted as the senior author's PhD dissertation at the University of Miami and supported by NIMH grant MH-14914.

Sixty-four preschool children were individually trained on a task requiring them to recognize an isolated phoneme in a word context. A learning set design encompassing 192 trials over eight days was employed. The major factors investigated were: the presence of a redundant visual cue; phoneme type (stop vs. continuant); phoneme position (initial…

A long-range investigation is being made to define the characteristics required of a television system to simulate a visual environment which will permit target acquisition performance comparable to that obtained in the real world. In this portion of the investigation, target recognition performance under direct viewing conditions was compared…

Verbal self-instruction was employed in training impulsive first-grade children to perform visual discrimination matching tasks. Posttests, following the four training conditions, showed that while strategy training increased latency, self verbalization both increased latency and reduced errors. (Author/DEP)

Examines 3-month-old infants' perception of "camouflaged" forms that were only visible when moving. Shows infants effectively use kinetic information to organize visual input in higher-order structures. (HOD)

Results of 7200 responses recorded from 180 children indicate that there is a tendency for stimuli which are pigmented in the orange-red arc of the spectrum to have a high noticeability factor. (Author)
