Skin conductance and neuroendocrine responses provided indices of sympathetic arousal and stress responses, respectively.

Despite equivalent initial learning, stressed participants showed marked impairments in reversal learning relative to controls.

When exploring a visual scene, we frequently move our eyes to obtain high-resolution information from individual objects.

In addition, the results demonstrate that surface-feature continuity contributes to visual stability across saccades.In addition, the retinal locations of objects shift as the eyes rotate to change the point of regard.These natural consequences of a foveal visual system and a moveable eye create a problem of object correspondence and continuity that has been one of the central areas of research in vision science.We found that stress exposure led to marked deficits in updating affective responses to shifting sources of threat and that this deficit emerged from a failure to adjust learning rates to accurately reflect new patterns of aversive reinforcement.Our findings point to stress exposure as playing a causal role in reducing affective flexibility through selective learning mechanisms and have implications for healthy and clinical populations alike.

Additionally, reversal learning deficits across participants were related to heightened levels of alpha-amylase, a marker of noradrenergic activity.
