Four experiments (E1, E2, E3 and E4) investigated whether or not 5- to 7-month-old infants could detect auditory-visual relationships in audiovisual presentations of affective expressions, thereby perceiving the bimodally-presented expressions as unitary events. In E1, 16 infants were simultaneously shown two 2-minute films of a "happy"…

Despite external changes such as those of magnitudes, the functional properties of the visual system also improve with increased age. According to Jean Piaget's centration/decentration theory, the process of perceptual development might continue until adulthood and even after. However, perceptual development should not be understood in all of its…

It was discovered a few years ago that a child's capacity for academic learning was partially dependent on visual and audio perception. It was also found that the development of perception in these sensory modalities was sometimes deficient. Educators immediately began to devise programs for perceptual-motor training, but ignored the role of the…

Forty-two nursery school children were exposed to two procedures designed to assess their discrimination of orientation. Under one procedure, subjects had no difficulty in discriminating between stimuli which differed only in orientation. Under a second procedure, where color and size of stimuli were also varied, orientation proved to be a…

In the design of visual simulation equipment for training systems, one key decision is the nature of the image storage medium to be used. One consideration in this complex issue is the adequacy of the depth cues which can be derived from imagery based on two- rather than three-dimensional sources. Although motion parallax is a relatively minor…

This handbook, written for parents, teachers, and others working with children for the purpose of early recognition of defective visual perceptual functioning, presents a training program designed to improve visual perception and suggestions for implementation of this program. To assist the trainer in establishing a beginning level for training,…

The sensory modality of a task and the modality of a retroactive interfering activity were systematically covaried in order to test two models of intersensory functioning. Subjects were 40 ten-year-old boys and girls. (BD)

Learning music can help children with reading readiness and beginning reading skills. (MKM)

In order to evaluate the effectiveness of the Wechsler Intelligence Scale for Children (WISC) in discriminating auditory or visual deficits, 121 learning disabled children (mean age 100 months) were tested. (PHR)

This study investigated infants' differential responding to novel and familiar stimuli after familiarization in a different sensory modality. Results showed that infants gain information about the shape of objects from their oral experience with them and that this information can be transferred to the visual modality. (Author/JMB)

Development of the relation between skills of visual and auditory pattern classification was studied at the second grade, sixth grade, and adult age levels using visual and auditory representations of the same abstract information. Results showed evidence of common processing of pattern class structure for the modalities, patterns, prototypes, and…

Four experiments assessed converging aspects of four-month-old infants' perceptions of visual patterns. Results together corroborate and extend previous findings that vertical symmetry has a special status in early perceptual development and that infants can perceive pattern wholes. (Author/AS)

Compares monocular depth perception with binocular depth perception in five- to seven-month-old infants. Reaching preferences (dependent measure) observed in the monocular condition indicated sensitivity to monocular depth information. Binocular viewing resulted in a far more consistent tendency to reach for the nearer object. (Author)

The development of space awareness should facilitate effective playing and coaching through increased ability to observe spatial arrangements as they apply to game strategy. (JD)

Results of this study suggest that 3-year-olds have a good deal of sensitivity to static depth information. (Authors)
