The present study examined Mexican-American and white subjects' response to same race stimulus persons who were differentiated only by the similarity of their beliefs to the subjects' beliefs. The prediction that a stimulus person whose beliefs are unknown and who is the same race as the subject would be responded to as if he had beliefs similar…

In a permanently changing environment, it is by no means an easy task to distinguish potentially important events from negligible ones. Yet, to survive, every animal has to continuously face that challenge. How does the brain accomplish this feat? Building on previous work in "Drosophila melanogaster" visual learning, we have developed an…

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…
