PSYCH 2H03 Lecture Notes - Subjective Constancy, Template Matching, Outline Of Object Recognition
Document Summary
Perception sensation: our perception goes far beyond the info given. We see the world in terms of objects. However, the visual stimulus (colours, lines) does not consist of objects. We hear what we expect to hear. Upper levels recognize objects and give us the conscious recognition of what the objects are. Physical characteristics of stimulus influence perception. Knowledge and expectations influence perception: parsing: to disassemble a stimulant into its individual parts. Size constancy: size of objects around us are unchanging. Emergence: reification: the constructive/generative aspect of conception. The perception that you experience contains more spatial info than the sensory stimulus that you are looking at. You are imposing more info to what you are looking at. We impose order on nothingness based on arrangement. Invariance: angles of objects don"t matter. We know that the object is still the same object. Closure: tendency to fill in gaps and perceive a whole object (imposing lines).
