The purpose of this study was to determine the sources of visual information used by highly skilled tennis players in anticipating their opponent's shots. In Experiment 1, motion analysis of the strokes showed that the relative motion between the racquet and forearm was different between the ground strokes and lobs, but there were no reliable…

Two experiments compared responses of 5-month-old infants to a live person, the person's photograph, photographs of dissimilar persons, and photographs of similar persons. Results indicated that infants use gross physiognomic features to perceive similarity between live persons and their photographs. (Author/JMB)

Investigates the effects of qualitative and quantitative factors on the perception of mechanical causality through a photographic animation technique. (MB)

Increase in visual perceptual ability will result in a concomitant increase in reading ability. (CK)

Describes an automated system which administers the Hidden-Figures Test and the Embedded Figures Test electronically. (RW)

Two-month-old infants were examined to determine whether, during localization of peripheral target, step size and number of steps were determined prior to the first saccade in a localizing series. It was found that on the majority of trials, a series of saccades was made toward the target hemifield. (Author/RH)

Previous studies have found that the gaze direction of a centrally presented face facilitates response time (RT) to a lone peripheral target. The widely accepted interpretation of this finding is that gaze direction triggers a cortically mediated reflexive shift of spatial attention. In the present study we tested an alternative explanation, that…

Theorists have predicted that repetition blindness (RB) should be absent for nonwords because they do not activate preexisting mental types. The authors hypothesized that RB would be observed for nonwords because RB can occur at a sublexical level. Four experiments showed that RB is observed for word-nonword pairs (noon noof), orthographically…

This study tested whether multiple-object tracking-the ability to visually index objects on the basis of their spatiotemporal history-is scene based or image based. Initial experiments showed equivalent tracking accuracy for objects in 2-D and 3-D motion. Subsequent experiments manipulated the speeds of objects independent of the speed of the…
