Eye gaze has been shown to be an effective cue for directing attention in adults. Whether this ability operates from birth is unknown. Three experiments were carried out with 2- to 5-day-old newborns. The first experiment replicated the previous finding that newborns are able to discriminate between direct and averted gaze, and extended this…

The present study investigates visual orienting to directional cues (arrow or eyes) in adults with high functioning autism (n = 19) and age matched controls (n = 19). A choice reaction time paradigm is used in which eye-or arrow direction correctly (congruent) or incorrectly (incongruent) cues target location. In typically developing participants,…

The functions of spaces between words in adult reading of text were investigated in three experiments. Results were consistent with a two-process theory in which filling parafoveal spaces disrupts guidance of the next eye movement and filling foveal spaces disrupts processing of the fixated word as well.

This study examined 4- and 6-month-olds' responses to static or dynamic stimuli using behavioral and heart-rate-defined measures of attention. Infants looked longest to dynamic stimuli with an audio track and least to a static stimulus that was mute. Overall, look duration declined with age to the different stimuli. The amount of time spent in…

The generalized optic acceleration cancellation (GOAC) theory of catching proposes that the path of a fielder running to catch a ball is determined by the attempt to satisfy 2 independent constraints. The 1st is to keep the angle of elevation of gaze to the ball increasing at a decreasing rate. The 2nd is to control the rate of horizontal rotation…

THE VARIOUS PROCESSES AND CONTROLS INVOLVED IN THE VARIATION OF EYE MOVEMENTS ACCORDING TO READING MATERIAL ARE DISCUSSED. RELEVANT RESEARCH LITERATURE IS CITED, AND AREAS REQUIRING ADDITIONAL RESEARCH ARE OUTLINED. LANGUAGE TEXT CONTROL AND THE CENTRAL NERVOUS SYSTEM AS POSSIBLE LOCI OF CONTROL FOR EYE MOVEMENTS ARE EXPLORED. EVIDENCE SUPPORTING…

Eye movement data indicate that perceptual efficiency increases with familiarization of graphemes. Research supported by grant from National Institute of Health. (DS)

When a visual target is identified, there is a period of several hundred milliseconds when the processing of subsequent targets is impaired, a phenomenon labeled the attentional blink (AB). The emerging consensus is that the identification of a visual target temporarily occupies a limited attentional resource that is essential for all visual…

An infant's unique style and temperament is thought to develop during a given small time segment as a consequence of the initiatives taken by caretaker or infant; usually an interaction of the two. (WY)

Reported are three series of experiments analyzing the development of the visual function of infants. The first experimental series was aimed at the investigation of infants' reaction to moving objects. The second experimental series dealt with the analysis of the development of binocular vision in infants. The goal of the third series was to…

READING READINESS IN YOUNG CHILDREN IS INFLUENCED BY SEVERAL FACTORS. PHYSICAL FACTORS OF VISUAL AND AUDITORY ACUITY, MOTOR COORDINATION, AND GENERAL GOOD HEALTH CONTRIBUTE TO READINESS. SOCIALLY, THE CHILD MUST BE SELF-RELIANT, COOPERATIVE, AND ABLE TO SHARE WITH OTHERS, HAVE GOOD LISTENING HABITS, AND BE ABLE TO ASSUME RESPONSIBILITY. MENTAL…

Studies have suggested attention-free semantic processing of natural scenes in which concurrent tasks leave category detection unimpaired (e.g., F. Li, R. VanRullen, C. Koch, & P. Perona, 2002). Could this ability reflect detection of disjunctive feature sets rather than high-level binding? Participants detected an animal target in a rapid serial…

A study investigated the size of the perceptual span within which adults use visual information to distinguish among letters as they read. The eye movements of fifteen college students were monitored as they read passages from a cathode-ray tube. On occasional fixations, letters in specified visual regions were replaced by other letters. The…
