This study examined whether 49 adults with mild or moderate mental retardation could perform reliably enough on the Penn Facial Discrimination Task to make this a useful research measure for evaluating visual-receptive processing. Results found subjects generally performed well above chance level, that retest reliability was reasonably high, and…

A survey of department chairs at colleges and universities investigated the administrators' perceptions of the importance of 26 administrative duties. Results reveal patterns in perceived importance of functions and perceptions of effectiveness in achieving them. Factors of hiring, discipline, gender, or orientation (manager, leader, developer,…

The Perky effect, identified in 1910, is the reduction in performance from the no-imagery to the imagery condition. A series of experiments with over 100 undergraduates and graduates shows that the reduction reflects a true reduction in visual sensitivity, not just alteration in criteria for responding or response organization. (SLD)

The relationship between general intelligence and the ability to ignore irrelevant stimuli appearing in the same visual field as an attended target was studied for 167 college students. Results indicate that psychometric intelligence does not tap visual focused attention. (SLD)

The complex ideas of William James on emotion were oversimplified during his lifetime, with his emphasis on the interpretation of the stimulus largely overlooked. Damaging scientific consequences of this mischaracterization are described. (SLD)

This study with 47 university students having reading disabilities, 15 students with other learning disabilities, and 12 nondisabled readers found that most nondisabled subjects used a phonological rehearsal strategy for words and nonwords, whereas students with reading disabilities consistently used a strategy of visual scanning for these tasks.…

Shows that color blindness, whether partial or total, inhibits literacy acquisition. Offers a case study of a third grader with impaired color vision. Presents a review of literature on the topic. Notes that people with color vision deficits are often unaware of the handicap. (RS)

In three experiments, children of three through six years of age were generally better able to reproduce a perceiver's perspective if a visual cue in the perceiver's line of sight was salient. Children had greater difficulty when the task hinged on attending to configural cues. Availability of distinctive cues affixed to objects facilitated…

This reprinted 1971 article reports on analysis of a 1968 survey of 221 research administrators in terms of organizational affiliation, duties and responsibilities, titles, and educational background. The paper argues that administration is like the doughnut hole, but research is the doughnut, and points out that research as an activity needs to…

The effect of background color on the perception of color by students is discussed. Explanations on why students only see certain colors when viewing colored marks on a blackboard through different color filters are provided. (KR)

A large body of data is reviewed to support a new theory of motion perception described by S. Grossberg and M. E. Rudd (1989). The Motion Boundary Contour System is used to explain classical and recent data about motion perception that have not been explained by other models. (SLD)

A sample of 48 children with and without musical training were presented with a melody of 9 notes and asked to select the line drawing that best depicted the melodic contour. Findings indicated a lengthy course of development of sensitivity to diatonic scale structure and suggested that musical training may enhance acquisition of this type of…

Event-related potentials (ERPs) of children and adults were measured while subjects observed pictures of facial expressions. Adults had greater ERP responses to happy than to angry faces, whereas children had greater ERP responses to angry than to happy faces. (BC)

This study compared 20 children (ages 8-14) with either autism or receptive developmental language disorder (RDLD) to 10 controls in their ability to detect frequent and infrequent randomly presented auditory stimuli. Only the children with autism demonstrated an abnormally small amplitude of the P3b, a component of the event-related brain…

This study evaluated the peripheral and central auditory functioning (and thus the potential to perceive obstacles through reflected sound) of eight totally blind persons and eight sighted persons. The blind subjects were able to process auditory information faster than the control group. (Author/DB)
