PSYB51H3 Lecture Notes - Lecture 4: Extrastriate Body Area, Illusory Contours, Two-Streams Hypothesis
Document Summary
Some ventral stream areas: lateral occipital complex (loc): perceiving and recognizing objects. Present in each hemisphere: parahippocampal place area (ppa): scenery locations, fusiform face area (ffa): facial recognition, extrastriate body area (eba): body recognition, dorsal stream: processes where, how info; fast but colourblind, ventral stream: processes what info. Broad generalization: cross connections, feedback as well as feedforward: object perception: the result of combining features into objects; middle vision, object recognition: when a perceived object representation is matched to a representation encoded in memory. These memory traces contain information about object categories: object identification: memory traces (o. r. ) contain info about specific object, object naming: recognized objects usually have semantic labels and names assigned to them; language functions. Challenges of seeing curved lines, gaps, and overlaps: gestalt law: set of rules describing which elements in an image will appear to group together.
