summaryAnimals and people integrate information acquired at different times when responding to novel situations or problems. For example, after being attacked by a boy at school, a child may become fearful of places where the boy had been previously encountered; and after learning the relationship between a particular sound and danger, an animal may become fearful of places where it had previously heard that sound. In the laboratory, this type of integration can be studied using sensory preconditioning protocols in which animals (rats) integrate innocuous sensory information acquired at time 1 (e.g., a sound is paired with a light) with emotional information acquired at time 2 (e.g., the light is paired with brief but aversive foot shock) and, thus, express fear to a stimulus that was never paired with danger at time 3 (e.g., the sound). The project that I will describe uses sensory preconditioning protocols to examine how the brain integrates sensory and emotional information. Specifically, I will present a series of experiments which show that the way in which rats integrate sensory and emotional information depends on characteristics of the stimuli to which they are exposed (e.g., their familiarity) and has consequences for learning about the danger. These experiments are part of a larger research program which aims to advance our understanding of how fear is processed in the mammalian brain. The findings will be discussed with respect to this program and different theories of information processing.
