Butler (1980) compared errors representing intrusions and mislocalizations on 3x3 letter displays under pattern-mask versus no-mask conditions and found that pattern masking increased character mislocalization errors (naming a character in the display but not in the target position as being the target) over intrusion errors (naming a character not…

This study explores the reason why very young infants are unable to respond differentially to faces and the cause for developmental changes in infant face perception by age 3 months. Linear systems analysis (LSA) and the contrast sensitivity function (CSF) were used to estimate the facial pattern information available to 1- and 3-month-old…

The processing of mental structures in perception appears to be serial, in that viewers can fill in missing parts from an impoverished stimulus following a top down process. To investigate the effects of unfamiliarity, complexity, and legibility on object and layout perception of unfamiliar stimuli, ten subjects were shown one of four ribbon…

Human infants are sensitive from birth to some intrinsic properties of objects; they are also sensitive to position. During the first weeks of life, pertinent dimensions of differentiation between objects are relative to global properties of the entire object or pattern. Position is defined by the direction of a displacement: the trajectory…

Described are three experiments which probed children's sensitivity to structure or organization in visual patterns. Each experiment employed a different paradigm (complexity judgment, discrimination learning, recognition learning, and memory) in order to tap different aspects of children's use of structural information. Subjects were children in…

Two experiments evaluated the effects of mnemonic training upon 5- and 10-year-old children's learning and retention of patterns at varying intervals. Subjects were 172 middle class children evenly distributed across the two age groups. Experiment I investigated the effects of individual strategies (perceptual exploration, organization of…

Perceptual units are involved in the reading process in a particular way. Reading starts with patterns of visual perception visual stimuli in combination with either previously learned information or a strategy for selectively attending to part of the stimuli. Whether the visual pattern selected for deeper information processing is a letter, a…

Aspects of problem-solving measured here are delay of gratification, field-dependence independence, and the relection-impulsivity dimension. The following hypotheses are proposed (1) Those subjects who score high on externality will not delay gratification as those who score low, but they will score lower on measures on field-independence than…

Individual differences in perceptual information processing were tested using 327 ten year old children, with verbal tasks representing successive information processing and spatial tasks representing simultaneous information processing. Three sets of tasks, (1) visual/reconstruction (V/R), (2) visual/verbal (V/VL), and (3) verbal/reconstruction…
