Discusses the role of visualization of information in learning. Theorizes that the comprehension of visualizations is a process of structure mapping between a visuo-spatial configuration and a mental model. Tests the model and finds differences in the use of text and picture information to answer different kinds of text questions. (DSK)

Investigates the size and shape of the effective visual field in Chinese reading by systematically manipulating the availability of meaningful information on both sides of a fixated character. Shows that the effective visual field was asymmetric and skewed in the direction of scanning with a highly limited size, composed of the fixated character…

Four studies assessed a cognitive explanation for development of infants' preference for attractive faces: cognitive averaging and preferences for mathematically averaged faces, or prototypes. Findings indicated that adults and 6-month olds prefer prototypical, mathematically averaged faces and that 6-month olds can abstract the central tendency…

Three experiments investigated whether 4-month-olds would attend to and utilize the global configuration ("good form") of a partly occluded, moving object to perceive its unit and coherence behind the occluder. Results indicated that curvature per se provided information in support of completion, in addition to global configuration and…

Three experiments investigated children's understanding of inference as a knowledge source. Most 4- to 6-year-olds did not rate a puppet as more certain of a toy's color after the puppet looked at the toy or inferred its color than they did after the puppet guessed the color. Most 8- and 9-year-olds distinguished inference and looking from…

The saccadic eye movements, generated during a visual oddball task, were compared for 10 autistic children, 10 children with attention deficit hyperactivity disorder, 10 dyslexic children, and 10 typically developing children. Several abnormal patterns of saccades were found in the autistic group. (DB)

Studies with 65 adults found two new visual processing tasks, visual change detection and visual movement detection, to be correlated with inspection time and the nonverbal scores from the Alice Helm 4 test of general intelligence. Results are discussed in terms of the correlation between inspection time and intelligence and the psychobiological…

Developing visual communication media technologies, such as computerized television, three-dimensional video, digital video interactive (DVI), and high-definition television hinder rather than enhance viewers' perceptual processes, understanding, and aesthetic appreciation of visual messages. Visual communication media researchers should reach out…

Two experiments examined visual attention in 5- to 13-year olds who were hearing or deaf with or without cochlear implants. Findings indicated that visual selective attention changes occurred around 8 years for all groups, with deaf children without cochlear implants performing less well than others. Differences between deaf children with and…

Examined visual search for compound patterns in 6-, 8-, 10-, and 22-year-olds. Found large improvements with age in search rate for long-range targets; search rate for short-range targets was fairly constant across age. This pattern held regardless of ease of perceptual access to target, supporting the hypothesis of different processes involved at…

Investigated 4- and 7-month-olds' perception of transparency, using computer-generated achromatic or color displays depicting a semitransparent box occluding the center of a rod. Found that 4-month-olds indicated perception of transparency in color but not in achromatic displays. Seven-month-olds showed some evidence of transparency perception in…

Used event-related potentials to novel and primed upright and inverted faces to examine evidence of repetition priming in 6-month-olds. Found that repeated faces demonstrated greater negativity than novel faces, and upright faces demonstrated greater negativity than inverted faces. Comparisons with adults tested in a similar experiment support the…

A rather consistent finding in studies of perceived (imagined) compared to actual movement in a reaching paradigm is the tendency to overestimate at midline. Explanations of such behavior have focused primarily on perceptions of postural constraints and the notion that individuals calibrate reachability in reference to multiple degrees of freedom,…

People presume that the light source in pictures comes from above, and there is some evidence that this phenomenon also demonstrates lateral biases. When investigators present multiple ambiguous stimuli or visually complex objects, people assume that the source of light is from above, and to the left. However, when single relatively simple stimuli…

When presented simultaneously with equally discriminable, but unfamiliar, visual and auditory stimuli, 4-year-olds exhibited auditory dominance, processing only auditory information ( Sloutsky & Napolitano, 2003). The current study examined factors underlying auditory dominance. In 6 experiments, 4-year-olds (N181) were presented with auditory and…
