PSYB51H3 Lecture 8: Perception lecture 8
Document Summary
Under certain conditions we are very good at scene perception. We perceive things globally , don"t need to analyze every single little detail, we are able to extract salient information from photos, multiple dimensions to categorize certain aspects of a scene. The details in one picture or other global features are very similar we have to use other local strategies to tell the differences. We don"t represent them at a first glance. We can use attention to zoom into details and process them one at a time. Selective attention is a cognitive brain mechanism that enables one to process relevant inputs, thoughts or actions while ignoring others that are less important, irrelevant or distracting. Attention is not arousal; a global state of the brain reflecting an overall level of responsiveness (also known as affect intensity in the context of emotions) Early selection or early with adaptable filter system. Late selection even semantic processes can remain unattended/unconscious.
