Conflicting recommendations exist in the literature regarding the optimal order of stimulus presentation when teaching auditory-visual conditional discriminations. The present study examined the generality of a previously demonstrated advantage of presenting the auditory sample before visual comparisons (sample-first condition) over the reverse…

Infant responses to adult-defined unattractive male body shapes versus attractive male body shapes were assessed using visual preference and habituation procedures. Looking behavior indicated that 9-month-olds have a preference for unattractive male body shapes over attractive ones; however, this preference is demonstrated only when head…

It has been claimed that exposure to distorted faces of one sex induces perceptual aftereffects for test faces that are of the same sex, but not for test faces of the other sex (A. C. Little, L. M. DeBruine, & B. C. Jones, 2005). This result suggests that male and female faces have separate neural coding. Given the high degree of visual similarity…

This study examined the use of an antecedent-based intervention to reduce the vocal stereotypy of a student diagnosed with Autism within the general education classroom. The student displayed frequent nonfunctional speech and disruptive vocal sounds. An antecedent-based intervention, involving the use of qualitatively different cards--to cue the…

Subjects with PDD excel on certain visuo-spatial tasks, amongst which visual search tasks, and this has been attributed to enhanced perceptual discrimination. However, an alternative explanation is that subjects with PDD show a different, more effective search strategy. The present study aimed to test both hypotheses, by measuring eye movements…

Many everyday matching tasks taught to persons with developmental disabilities are visual-visual non-identity matching (VVNM) tasks, such as matching the printed word DOG to a picture of a dog, or matching a sock to a shoe. Research has shown that, for participants who have failed a VVNM prototype task, it is very difficult to teach them various…

Based on a master's thesis submitted to the University of Illinois.

Sex specific biases in visual images was explored. When photographs of male and female faces were presented in a deliberately ambiguous manner, university students overreported the number of male faces and underreported female faces. The results are predictable with the variation of generic sentences shown with the photographs. (VM)

Male school children of three age levels were tested on a 2-choice visual discrimination task that varied in spatial continguity of stimulus, response, and reward. Separation of stimulus from response and reward was found to retard learning. (WY)

Eighteen profoundly retarded men (mean age 41) were given repeated presentations of a two-choice visual discrimination using a modified Wisconsin General Test Apparatus and two probabilistic reinforcement schedules counterbalanced for order. (Author)

THE LABELING AND DISCRIMINATION OF COLORS WERE STUDIED IN CHILDREN WITH PRIMARY READING RETARDATION AND IN A MATCHED GROUP OF NORMAL CHILDREN. TEN MALE STUDENTS IN MICHIGAN REPRESENTING AN AGE RANGE OF 9 YEARS 10 MONTHS TO 14 YEARS 10 MONTHS WERE CHOSEN AS SUBJECTS. DEVELOPMENTAL, MEDICAL, EDUCATIONAL, NEUROLOGICAL, PSYCHIATRIC, AND PSYCHOMETRIC…

Facial configuration and height were systematically varied as four different strangers--a male and female child, a female adult and a small female adult (midget)--each approached 40 different infants. The infants responded as if there were 3 classes of persons, suggesting that both size and facial configuration cues were used. (Author/SB)

Research indicated that visual discrimination training could compensate for the impulsive response style of first-graders on reading tests. (GW)
