Assesses subjects' information output after presentation of pictorial, word, and sentence stimuli. Output is measured in two modes of response: reconstruction and verbal description. Complexity of the stimuli is demonstrated to have important effects on perceptual information processing. (DP)

The role of perceptual discrimination in the development of the ability to selectively process information was investigated. Using an incidental learning paradigm, the discriminability between relevant and irrelevant stimuli was experimentally varied in two ways: (1) contiguity versus non-contiguity in spatial arrangements and (2) alternating…

A total of 100 third and ninth grade students participated in a study to determine how children of different ages perceptually segment a continuing behavior sequence presented on a television program. The children were shown a short segment from a motion picture on a videotape viewer. Following the viewing, the children completed unitizing…

One question prompting the present research concerned the relation between performance under tachistoscopic'' conditions where exposure durations are too brief to permit active overt visual search, and performance when overt search is possible. (Author)
