Visual behavior of infants was assessed with multiple discrimination tasks week to week from four to seven months of age. Task to task reliability was low, but attentional averages from week to week were reliable. Generally, infants with shorter fixations showed more novelty preferences, and infants' shift rate improved with age. (SKC)

Forty-six full-term and 54 high-risk preterm infants were tested at six, seven, and/or eight months of age (corrected age for preterms) on assessments of visual recognition memory and tactual-visual cross-modal transfer. Scores significantly predicted Stanford-Binet IQ scores. Stability coefficients attained the highest degree of predictive…

The spatial layout of visual displays was evaluated by means of three magnitude estimation tasks and one reproduction task. Each stimulus display consisted of 16 randomly-drawn, two-digit numbers. Six different spatial layouts, or display types, were used: systematic vs. random spatial order of numbers; regular vs. irregular boundaries of the…

Forty five-year-olds compared two arms of an L-shaped figure on-axis or perpendicular to axis inside circles of different diameters. In making perceptual judgments about the relative length, the children tended to describe the on-axis line as longer. The context model of visual anomalies was supported. (Author/CM)

A 2 x 2 x 4 factorial design was utilized to investigate the effects of sex of perceiver, race of expressor (Negro and White), and mode of presentation of stimuli (audio and visual, visual only, audio only, and still pictures) on perception of emotion (POE). Perception of seven emotions (anger, happiness, surprise, fear, disgust, pain, and…

Visual acuity as a function of target position and density was measured in a letter recognition task. A homogeneous pattern of equally-spaced elements was tachistoscopically exposed, where the target was never located at the boundaries of the pattern. The target was marked with a spatial cue to control attentional processes. With such a spatial…

This investigation of cognitive effort begins with a review of cognitive principles relating to memory and graphic encoding of information. The cognitive framework described allows explanation of improved memory due to reparsing of graphic representations. It also provides the basis for optimizing graphical material design to insure best retention…

The attentional blink refers to the finding that the 2nd of 2 targets embedded in a stream of rapidly presented distractors is often missed. Whereas most theories of the attentional blink focus on limited-capacity processes that occur after target selection, the present work investigates the selection process itself. Identifying a target letter…
