Results of a study involving control, learning disabled, and attention deficit disorder with hyperactivity (ADD-H) children (14 per group, aged 8-10 years) revealed that LD and ADD-H Ss habituated more rapidly, but they also encoded fewer aspects of the stimulus field than control Ss. (CL)

An expanded assessment model examining physiological conditions, durational events, and behavioral histories is suggested as one way to understand the stimulus events controlling aggression of developmentally disabled persons. Implications for more effective treatment are considered. (CL)

Habituation to single female faces and to single geometric patterns was observed separately in two groups of infants who participated in two sessions separated by 10 days. Habituation was found to be distributed into three patterns and showed moderate but significant reliability between assessment sessions. (Author/RH)

Response latencies of 27 learning disabled (LD) and 27 normal control boys (8-11 years old) were compared on a picture-word interference task. Both LD and control Ss exhibited greater interference effects (longer response latencies) when naming pictures (versus naming words) and when categorizing words (versus categorizing pictures).

Results of a study involving 60 autistic children (three-16 years old) showed that equivalence training was more effective than functional object-use in improving posttest scores on visual overselectivity. (Author/CL)

Two experiments involving six profoundly retarded Ss (3-18 years old) evaluated a formal method for identifying reinforcers. Results revealed that preferred stimulus conditions typically produced higher rates of responding than did either baseline or nonpreferred stimulus conditions, suggesting that the procedure can assess reinforcer value for Ss…

The authors suggest that line graphs that average response frequency over long periods obscure the major rate changes that indicate sources of behavioral control. A scatter plot can make patterns of responding identifiable and, in turn, suggest environmental features that occasion undesirable behavior. Use of scatter diagrams is illustrated in…

Reports the measurement of response latencies and the recording of eye movements in a task in which children of approximately five-and-a-half years counted one to eight dots presented in different configurations. (Author/RH)

Bibliography of research on pictures and imagery is organized according to major sections of general-purpose taxonomy, i.e., theoretical approaches to picture perception; picture perception research; memory for pictures; concept learning, problem solving, and cognitive skills; learning from prose; affective picture responses; pictoral media design…

Results of three experiments suggest that groups of schizophrenic, younger normal, and older normal children used a serial information-processing strategy while performing on a partial report version of a span of apprehension task. Impairment of schizophrenic children on the partial report versions seemed to reflect inefficiencies in the…

Compares comprehension monitoring skills of younger (five- to six-year-old) and older (eight- to nine-year-old) children. Subjects examined ambiguous and incomplete pictorial instructions for making two models and were asked whether they needed additional information to make the models. (RH)

The relationship between the use of concrete objects and pictorial representations of those objects when teaching noun labels to 3 autistic boys was analyzed. Although results indicated no consistent functional relationship between the two types of stimulus presentation, there were varying degrees of generalization between the two conditions.…

Five groups--second year students, psychiatric inpatients, incoming students, mothers, and relocated women were tested with verbal samples to examine the effects of cognitive anxiety as a construct implying a reaction to being unable to anticipate and integrate experiences meaningfully. The measure used was found to be valid. (Author/DEP)

A probe-type serial memory task was used to determine whether 3-dimensional objects would produce better recall than colored pictures of the same objects in elementary school students with low IQ's. (ST)

Discusses the positive aspects of verbalizing ideas in order to provide a frame of reference which serves to clarify the concept. (Author/HV)
