Examines the relationship between the magnitude of the stimulus familiarity effect and the level of stimulus incongruity. Results support a theory of visual selection based on information-conflict resolution. (Author/ED)

The eye movements of subjects, ages 4 through 62, were recorded by a corneal reflection technique during familiarization with and recognition of random patterns of luminous dots. Findings were consistent with the views of both Soviet researchers and Piaget, that overt, perceptual activity diminishes with increasing age. (Author/SDH)

Results from three studies involving college, third grade, and kindergarten subjects, suggest that individuals across a wide age range are able to use the visual properties of a stimulus for only a very brief period as the basis for making matched judgments. (Author/SDH)

This study was designed to investigate whether age differences in timesharing performance would be found if the baseline performance of younger and older children was experimentally equated. Two groups of twelve 8-year-olds and one group of twelve 13-year-olds participated. Each subject performed a compensatory tracking task and an auditory…

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

This article reported the development of a method aimed at exploring the relations among covert muscle behavior, mental imagery, and the perception of external stimulation. (Author/RK)

The theory is developed and contrasted with other theories of pattern recognition in which concepts such as stimulus generalization, tuned detectors, and preprocessing play major roles. A relation of this theory to problems encountered among disabled readers ("dyslexics") is also brought out. (Author/BJG)

Investigates extent to which perceptual factors of speed and flexibility of closure represent more general processes also operating in cognitive and personality domains by including in a single factor analysis perceptual tests and new tests requiring cognitive abilities resembling closure abilities operating in the perceptual domain.

Clarifies issues involved in use of heart rate as index of newborn attentional responsivity by reviewing related studies and concluding that heart rate variability can be used in studying attentional responsivity state, and intra-individual and individual variables. (ED)

This experiment (involving kindergarteners and fourth graders) examined the development of the ability to encode, store, and retrieve verbally-or visually-presented material when the modality of the test stimulus was varied. (JMB)

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.

Thirty learning disabled and thirty nondisabled children (mean age 10 years) were compared on a paired associate learning task that simulated the process of sight word learning. Two instructional variables (response competition and stimulus complexity) that have been hypothesized as contributing to overloading in learning disabled children, were…
