PSYCH 120A Lecture Notes - Lecture 9: Peanut Butter, Inattentional Blindness, Ambiguous Image
Document Summary
We have separate feature maps which are consulted without attention. Might have separate maps for squares, circles, colors, etc. Maps are generated during the preattentive stage. Focused attention stage: combine features together to create object representations. Attention is a glue that binds separate features together at the same location. Attention moves from one location to another in order to bind features. When neurons are firing together, the synchrony indicates that they"re responding to the same object. Synchrony should be different for different perceptions of an ambiguous image. Broadbent"s filter model suggests an attentional filter blocks out info early so that. Brain biases processing against unattended information and toward attended info immediately. Selection of attended info occurs after some analysis of the input. Even if we don"t consciously recognize the influence of unattended information, it still influences our behavior so it is being perceived.
