title: Facilitative and inhibitory factors in visual texture discrimination.
abstract: In this paper we consider some spatial and temporal properties of visual textures which either inhibit of enhance their discrimination. From exposure time and texture mixing studies two findings emerge. First, it is clear that the spatial summation process involved in texture discrimination has a time course consistent with counting models for decision making. Secondly, the receptive field structures of salient texture features, in particular-orientation, seem to involve simple excitatory center and inhibitory surround mechanisms.
