PSYB51H3 Lecture Notes - Lecture 8: Zoom Lens, Frontal Lobe, Superior Temporal Gyrus
Document Summary
Week 8 july 3 rd , 2015. Early vs. late selection: stream of information from earlier stages up to higher-level brain areas (several synapses) up to executive functions (structures embedded in frontal cortex). Metaphor of pipelines: early selection or early with adaptable filter system, late selection: Although you"re told to do something you pay attention to something else. E. g. , being told to listen to a sentence in the left ear yet process language in the right ear: multilevel filtering, perceptual (or cognitive) load: E. g. , every time you see x" you have to push a button, but not when you see o . Higher perceptual load if it"s x"s and n"s. Spotlight (or search light) model: attention is confined to a coherent region of space and can move from one point to the next. Attention can split into more than one focus; not necessarily coherent region in space. E. g. , multiple object tracking (tracking 4 dots)
