PSYB51H3 Lecture Notes - Lecture 8: Zoom Lens, Receptive Field, Superior Colliculus
Document Summary
In green flow of information from the retina to lgn and v1 and other higher level vision areas. Information flow from sensory inputs sensory and perceptual analysis high level of analysis executive functions which will give you a response: pipeline of information processing could intersect at different stages of flow of information. Multi-level filtering what works best in a given situation = control at multiple levels. Perceptual load degree to which the processing (in green) is effortful: doing something computationally expensive cognitively/perceptually difficult. In graphs increase activity in motion (brain activity); therefore, presented with motion stimulus = low load. If trying to find someone in a crowd zoom out and bigger fixation/spotlight. Problems with spotlight and zoom lens models: attention shifts rather instantly. Spotlights shift continuously have a time where you would pay attention to things between the 2 faces that you want to pay attention to.
