Participants first became familiar with an image showing moderate symptoms of the skin cancer melanoma. In a generalization test, they indicated whether images showing more and less pronounced symptoms were "like the original." Some groups (cancer context) were told that the images depicted melanoma and that the disease is deadly unless…

Among the findings were that the treatment procedure produced immediate and substantial suppression effects on the self-injurious behavior, which generalized to the nontraining environment and endured over an eight-month interval. (Author/DLS)

We have used a genetically tractable model system, the fruit fly "Drosophila melanogaster" to study the interdependence between sensory processing and associative processing on learning performance. We investigated the influence of variations in the physical and predictive properties of color stimuli in several different operant-conditioning…

Describes a computer tutorial that teaches the fundamentals of stimulus generalization in operant learning. Concepts covered include reinforcement, discrimination learning, stimulus continua, generalization, generalization gradients, and peak shift. The tutorial also reviews applications in human and animal situations. The content is appropriate…
