The effects of gaze direction on memory for faces were studied in children from three different age groups (6-7, 8-9, and 10-11 years old) using a computerized version of a task devised by Hood, Macrae, Cole-Davies and Dias (2003). Participants were presented with a sequence of faces in an encoding phase, and were then required to judge which…

This paper provides three representative examples that highlight the ways in which procedures can be combined to study interactions across traditional domains of study: segmentation, word learning, and grammar. The first section uses visual familiarization prior to the Headturn Preference Procedure to demonstrate that synchronized visual…

The abilities of 19 adult students with dyslexia and 19 students without dyslexia to recall number facts were compared. Despite being matched for estimated IQ, the dyslexic students were less accurate than the non-dyslexic students when answering subtraction and multiplication questions. When the dyslexic students answered addition and subtraction…

Current theories of environmental cognition typically differentiate between an online, transient, and dynamic system of spatial representation and an offline and enduring system of memory representation. Here the authors present additional evidence for such 2-system theories in the context of the disorientation paradigm introduced by R. F. Wang…

How long does it take to form a durable representation in visual working memory? Several theorists have proposed that this consolidation process is very slow. Here, we measured the time course of consolidation. Observers performed a change-detection task for colored squares, and shortly after the presentation of the first array, pattern masks were…

Case reports and sensory inventories suggest that autism involves sensory processing anomalies. Behavioral tests indicate impaired motion and normal form perception in autism. The present study used first-person accounts to investigate perceptual anomalies and related subjective to psychophysical measures. Nine high-functioning children with…

In this age of proliferating visual communications, there is a permissiveness in subject matter, content, and meaning that is exhilarating, yet overwhelming to interpret in a meaningful or consensual way. By recognizing visual statements, whether a piece of sculpture, an advertisement, a video, or a building, as communication, one can approach…

This paper examines how temporal and spatial observation variables can drastically alter a visitor's comprehension of the phenomena depicted by a museum exhibit. The focus is on a tornado exhibit at the Exploratorium, a museum of science and human perception in San Francisco (California). Videotaped recordings of 10 children interacting with the…

Reviewed are clinical and laboratory studies on the auditory-visual perception of speech by normal and hearing impaired children and adults. (Author/LS)

Evidence on the poorer spatial visualization ability in various Negro populations compared to the White populations and on the direction and magnitude of sex differences in spatial ability relative to other abilities suggests the genetic hypothesis that spatial ability is enhanced by a sex-linked recessive gene and that, since the 20-30 percent…
