Examined which of the attentional operations underlying exogenous orienting (disengaging, shifting, and/or engaging) improves with age in children from 6 to 14 years old. Found that disengaging attention alone distinguished between younger and older children's performance, regardless of whether attention alone or attention and associated sensory…

The SeLective Attention Model (SLAM) performs visual selective attention tasks and demonstrates that object selection and attribute selection are both necessary and sufficient for visual selection. The SLAM is described, particularly with regard to its ability to represent an individual subject performing filtering tasks. (TJH)

A series of 6 experiments involving 210 subjects from a college subject pool examined orthographic priming effects between briefly presented pairs of letter strings. A theory of othographic priming is presented, and the implications of the findings for understanding word recognition and reading are discussed. (SLD)

Auditory-visual pattern equivalence and temporal-spatial equivalence of 72 children of 7-17 years were examined. Data indicated that aspects of intersensory integration were still developing between the ages of 13 and 17. Accuracy in performance increased with age for intra- and intersensory matching. (RH)

A profile analysis procedure was used with the Carrow Auditory-Visual Abilities Test to aid in the identification of systematic modality preferences in two preschool children with articulation disorders. Critical values are identified to facilitate the identification of the child's strengths and weaknesses at the subtest level. (Author/DB)

Investigates age differences in children's processes of simultaneously comprehending the auditory and visual content of a televised story. Reports a developmental increase in utilizing semantic content of both auditory and visual content to form a unified representation of narrated events. (MM)

Confirms that infants, like older children, are capable of responding categorically to stimuli of different shapes if these are similar in hue. (PCB)

Investigation of profoundly deaf adolescent students' ability to read signs in peripheral vision revealed a mean success rate of about 80 percent. Results support the supposition that peripheral vision may be linguistically and communicatively useful for deaf people, particularly as signs in isolation are more difficult to read than signs in…

Children aged 14 and 24 months were shown television depictions of adults manipulating toys in novel ways. Infants at both ages showed imitation of television models, even after 24-hour delays. This deferred imitation has social and policy implications as it suggests that television viewing can potentially affect infant behavior and development…

Uses a diode array spectrometer to explain why blue objects appear red when viewed through the yellowish amber lens of "blue blocking" sunglasses. (JRH)

This study compared visual word recognition (speechreading) in video sequences showing either full face or lips plus mandible to 26 normal hearing college students and 4 adults with bilateral sensorineural hearing loss. Percent phoneme correct scores were similar in the two conditions and scores significantly improved for the repeated measure in…

Adolescents identified letters presented to them on the basis of color. Subjects (n=20) with mental retardation exhibited facilitation when the target was identical to the target on the preceding trial but did not exhibit inhibition when it had been a distractor on the preceding trial. Inefficient suppression processes may result in performance…

Three experiments examined whether the perception and retention of feature relations, thought to be critical for object recognition in adults, are evident in early infancy. Three month olds' 24-hour retention was disrupted when features of a 6-item mobile were recombined, indicating that they not only encode feature relations but also remember…

Explores the relationship between virtual reality (VR) stimulation and perceptual equivalence. Topics include perceived realism; creating a virtual illusion; displayed realism; and VR as an instructional technology. (Author/AEF)

Tested 160 children on a Stroop-like day-night test that involved 2 rules. Also tested for whether remembering two rules alone was sufficient to cause difficulty. Concludes that the requirement to learn and remember two rules is not in itself sufficient to account for the poor performance of younger children (under five) in the experiment. (DR)
