Abstract: Sensory signals are highly structured in both space and time. These regularities allow expectations about future stimulation to be formed, thereby facilitating perceptual decisions about visual features and objects.

In my talk, I will discuss recent data that elucidate how temporal and spatial context change sensory computations in the visual system and modify perception and post-perceptual decision-making. I will also compare the effects of time and space with the effects of learnt statistical regularities on the neural and behavioral response.
