How are local orientation signals pooled?

Visual perception is capable of pooling multiple local orientation signals into a single more accurate summary orientation. However, there is still a lack of systematic inquiry into which summary statistics are implemented in that process. Here, the task was to recognize in which direction, clockwise or counter-clockwise, the mean orientation of a set of randomly distributed Gabor patches (N = 1, 2, 4, and 8) was rotated from the implicit vertical.

Does goal congruence dilate the pupil over and above goal relevance?

To better understand the mechanisms underlying preferential processing of affective stimuli (i.e., affective attention), it is useful to ask which appraisal dimensions characterize stimuli that capture affective attention.

Bending time: The role of affective appraisal in time perception.

Affective states are known to distort time perception, but it remains unclear why and how they do so. To test whether appraisal processes involved in affect may play a role in temporal distortions, we investigated bisection behavior during experimental events with varying appraisal values along three dimensions: goal relevance (high vs. low), goal type (approach vs.
