This study examined if listener behavior and responding by exclusion would emerge after training 3 participants with autism to tact stimuli. Tacts for 2 of 3 stimuli were directly trained using discrete trial training methodology and were followed by an auditory-visual discrimination probe in which auditory-visual discrimination by naming (i.e.,…

Informal education in museums is structured through movement in space. This article summarizes a range of research that examines the role of spatial layout in shaping the ways in which visitors explore, engage, and understand museums and museum exhibitions. It is demonstrated that behavior patterns are systematically linked to spatial…

Proposed is a neuronal network capable of learning pattern discrimination. (Author)

The present article discusses the possibility that behavioral recovery following brain damage is not dependent on the functional reorganization of neural tissue but is rather the result of the continued normal operation of spared neural mechanisms. (Editor)

Two variants of the habituation paradigm were used to investigate fine orientation discrimination and shape constancy in 34 young infants. Results demonstrate that conditions determine whether young infants show sensitivity to relatively fine variations in pattern orientation or give evidence of shape constancy with the same patterns. (HOD)

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)

Presents nine experimental studies investigating auditory and visual discrimination in very young infants. Results are discussed in terms of their implications for understanding habituation, cross-modal stimulation, receptive language development, and individual differences. Appendices include data on visual fixation duration and information on…

The Stroop effect is psychology's classic measure gauging the selectivity of attention to individual attributes of complex stimuli. The emotional Stroop effect gauges the influence on behavior of threat and emotional stimuli. The former taps central/executive processes abstracted from particular stimulus contexts, whereas the latter taps automatic…

This study investigated at the age at which infants become able to discriminate between their mothers and females strangers, as measured by differential patterns of pauses during the infants' crying while being spoken to by their mothers and female strangers. The subjects, 14 infants ranging in age from 7 to 20 days, were fed, burped, and changed,…

Boys (N=55) aged 8-11, categorized as impulsives by the Matching Familiar Figures test, participated in a study comparing the effects of three different techniques, designed to change an impulsive cognitive style on response accuracy and response latency. Subjects trained to increase response latency did show a significant increase in latency.…

Examines whether three-month-old infants can detect variations within the single expression category of smiling and whether individual differences in infants' sensitivities are related to identifiable mother or infant behaviors. (HOD)

THE BASIC INTENTION OF THE STUDY WAS TO INVESTIGATE MENTAL RETARDATION IN TERMS OF PERCEPTUAL AND RESPONSE ABILITY DEFINITIONS, TO TEST THESE ABILITY DEFINITIONS OBJECTIVELY, AND TO EVALUATE THEM AS THEY RELATE TO THE INTELLIGENCE FACTOR. BOTH PERCEPTUAL AND RESPONSE FACTORS WERE EXAMINED FROM THE STANDPOINT OF MENTAL DISTURBANCES WITH REFERENCE…

A comparison of observed classroom behavior, tonic and phasic physiological arousal level, and task performance of 98 male and female first-grade children revealed sex differences in only 3 of 18 variables. Many assumed sex differences may be negligible and teachers' expectations may influence their perceptions. (SB)
