Forty-eight neonates were randomly assigned to view a moving stimulus either in the horizontal or the upright position, with or without added vestibular stimulation and with or without pacifier sucking. Results indicate that vestibular proprioceptive stimulation, provided horizontally or semi-vertically, significantly enhanced visual tracking.…

Results indicate that for children in this study's age range orientation is a less salient discriminative cue than either size or color. (Author/MB)

To test perceptual responses, 120 subjects viewed 12 experimental and one controlled housing environments. Three levels of building form diversity were combined with four levels of space diversity in the experimental environments. Results indicated that amount of visual coverage of the field of view increased significantly with increases in both…

Response patterns of deaf and hearing children in matching visual stimuli employing the dimensions of color, size, orientation, and form were compared. (KW)

Results support the contention that infant attention should be divided into separate attention-getting and attention-holding processes. (Author)

Three experiments employed rectangles in stimulus identification tasks. It was concluded that the initial perceptual processing of rectangles is accomplished by separate dimensional analyzers operating in parallel. Observers adopt different decision strategies for negatively correlated sets and for single dimension sets when the number of…

Tested 61 randomly selected college students to determine whether methodologies employed in psycholinguistic investigation of sentence perception can be used to ascertain how screen media communicate. The paralinguistic techniques were not transferable to the examination of visual perception. More than 60 references are listed. (FM)

The hypothesis was that the two hemispheres have different functions in normal vision, the dominant one analyzing the "figure," and the nondominant the "background." The investigation examined responses of 41 female psychology students. Results were consistent with the hypothesis. (Author/RD)

Repeated observations of a colored form results in slower reaction-time responses to the familiarized stimulus than to a comparable novel stimulus due to alertness decrement and encoding facilitation. This two-factor theory of repetition was found to hold for words as well as for colors. (Author/BW)

Presents results of two experiments which measured contrast sensitivity function in infants. Information concerning development of visual acuity, low frequency attenuation, and sensitivity to contrast were collected. Results provide an approximate picture of and means for detection of infants' pattern information. (Author/DB)

This research reexamined the hypothesis that recognition is a developmentally stable component of the memory system. Recognition performance was compared across age groups. Particular attention was paid to the role of response biases and perceptual skills in developmental increases in recognition performance. (Author/DB)
