The Prototype Abstraction Lab (PAL) is devoted to the exploration of fundamental issues in human categorization, ranging from the variables known to shape concepts to the investigation of higher-order issues in categorization theory.
In PAL, we also investigate topics outside of category abstraction – visual selective attention, abrupt onset capture & encapsulated mechanisms embedded within complex cognitive processing, haptic memory & cross-modality transfer, recognition memory & retrieval, and multidimensional scaling as a geometric model of human memory - but mostly we study category abstraction.
