The results of this experiment indicate that continuous stimulation has a marked pacifying effect on young infants. (WY)

Outlines a method by which observation time as measured by visual fixation on an object in the visual field can be predicted for N items viewed simultaneously in the field when the time for observing each item presented singly is known. (Author/MG)

Subjects recalled the more rewarding stimuli significantly better. (MH)

Study supported by the Research and Development Center for Learning and Re-Education, University of Wisconsin, pursuant to contracts with the U.S. Office of Education.

Errors made by 5- and 8-year-old children asked to draw a model were investigated in two studies. Results from both indicated that 5-year-old children are more likely to produce visually accurate drawings than had previously been supposed; for both ages difficulty in producing accurate drawings occurred when drawing rules and conventions…

Three experiments demonstrate that the context of a two-object array greatly influences the way in which young children represent the array in their copies. Children were aware of differences in orientation and in the nature of paired objects and were concerned with marking these differences in their drawings. (RH)

The results offered little support for the hypothesis that teaching severely retarded learners to label stimuli would reduce the likelihood of stimulus overselectivity. (Author)

Shows how the visual differential theory provides a model that illuminates the effects of visual manipulation on communication. Includes illustrations. (GT)

Several propositions deduced from the discrepancy hypothesis were tested with four-month-old infants using random shapes in a habituation/discrepancy paradigm. (JMB)

Four-month-old infants' stimulus preferences were assessed using an operant paradigm with mobile reinforcers of different colors (blue, green). (Author/MP)
