Contextual Influence on Amygdala's Role in Fear Learning: Rat Pup Experiment
An experiment by Moriceau & Sullivan (2006) demonstrates how social context can modulate the amygdala's function in fear learning. When rat pups were conditioned with an odor paired with an electrical shock in their mother's absence, their amygdalas showed increased activation, and they developed an aversion to the odor. In contrast, when the mother was present during the same conditioning, there was no corresponding increase in amygdala activation, and the pups learned a preference for the odor. This highlights that maternal presence can inhibit the typical fear-learning response in the amygdala.

Contextual Influence on Amygdala's Role in Fear Learning: Rat Pup Experiment
A research study compares brain activity in two groups of participants: one group with a diagnosed anxiety disorder and a control group with no disorder. Both groups are shown a series of images, some of which are emotionally neutral and others designed to elicit a fear response. Based on the known function of a key brain structure in processing fear, which of the following outcomes would be most expected?
