Examines, in two experiments, 5-month-old infants' sensitivity to auditory-visual specification of distance and direction of movement. One experiment presented two films with soundtracks in either a match or mismatch condition; the second showed the two films side-by-side with a single soundtrack appropriate to one. Infants demonstrated visual…

Assesses preschoolers' and adults' relative ability to solve classification problems in which a similarity criterion is the only criterion appropriate for solution. Also investigates effects of the salience of individual dimensions on solution-relevant similarity classifications. (AS)

Measures of prenatal exposure in 123 infants to polychlorinated biphenyls (PCBs), cord serum PCB level, and maternal report of contaminated fish consumption predicted less preference for a novel stimulus on Fagan's test of visual recognition memory (VRM) at 7 months. Preference for novelty decreased in a dose-dependent fashion and postnatal…

Examines an avant-garde illustrated book and suggests that "deviant" books urge a kind of reading that gives visibility to the text and seeks out relationships created between two volumes--the book and its words. (DF)

Examines the relationship between preschool children's (n = 96) cognitive processing of video (V) and audio (A) information on television under four conditions: A/V match, A/V mismatch, V alone, and A alone. Results suggest that in regular television programs the video material simply appears to be more salient and more memorable than the audio…

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.…

Serial habituation of visual fixations was investigated through a design permitting cross-sectional, within-subject longitudinal, cohort longitudinal, and time-lag analyses. Results suggested that for all ages habituation was under way to the parts of the stimulus in order of the realitive saliencies. No one methodology appeared to significantly…

A strong test of exposure effects was made by eliminating confounding demand characteristics through the use of a between-subject design. Each subject viewed novel stimuli at a single frequency level, and then rated them on several affective scales. (Editor)

Five developmental experiments examine the role of context in visual search. (Author/JH)

The present experiment supports the hypothesis that the letter is the basic perceptual unit in letter, nonword, and word identification. (Author)

The separate effects of stimulus and response relative frequency were studied in two choice reaction time tasks containing many: 1 stimulus-response (S-R) mappings and 2 levels of S-R compatability. (Editor)

Kindergarten children were trained to make same-different judgments of either 2 or 4 standard figures under either 2 or 4 transformations before being transferred to a novel set of figures. (Editor)

Twenty subjects were pretrained with oral presentations of either three- or six-letter pseudowords exposed 0, 1, 5, 25, or 50 times. Then tachistoscopic duration thresholds were obtained for these pseudowords. (Editor)

The present research was designed to investigate the use of contextual information for facilitating word prediction in a visual task. (Author)
