Psychologists have long been captivated by the perception of animacy--the fact that even simple moving shapes may appear to engage in animate, intentional, and goal-directed movements. Here we report several new types of studies of a particularly salient form of perceived animacy: "chasing", in which one shape (the "wolf") pursues another shape…

Alerting, orienting and executive control of attention are investigated in five adult cases of dyslexia. In comparison with a control group, alerting and executive control were found to be generally intact for each case. Two spatial cueing tasks were employed. For the task requiring target detection, orienting difficulties were evident only in…

Attempts to replicate Gogel's (1972) observations with points of light and examines in addition whether the same results would be obtained if the binocularly nearer object was made visually more massive than the farther object and if the residual oculomotor cues were varied to produce different values of the reference distance.

The present study casts doubt on (1) the validity of assuming certain geometric illusions as being "perspective" related, and (2) the consistency of perspective explanation (constancy scaling) for geometric illusions. (Author)

Explores the possibility that measurable individual differences in hypnotic susceptibility or the ability to attend selectively to informational cues may account for a portion of the variability found in several types of geometrical visual illusions. (Author/RK)

Attempts to determine how the ability of African secondary students to understand pictures three-dimensionally changes, as the number of different types of depth cue increases in carefully stages. Also investigates the existence of interactions involving the different types of picture and differences in amount of formal training which people have…

This paper investigates the processes by which visual mental images--the precept-like short-term memory representations--are created from information stored in long-term memory. It also presents a new method for studying image generation. Three experiments were conducted using college students as subjects. In the first experiment, a Podgorny and…
