PSYB51H3 Lecture Notes - Lecture 7: Attentional Blink, Station Wagon, Electroencephalography
Document Summary
> entity of all the points and space, where for the two eyes there s zero disparity. 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. Arousal: a global state of the brain reflecting an overall level of responsiveness. > as your arousal increases, your attention decreases. Why we need attention: bottlenecks: it is impossible to process everything at once. Where does attention play a role: attention to vision. Attention to audition / touch / smell: attention across modalities, attention to thoughts, attention to motor tasks: ex. when you re doing something complex, it d change your motor complex. Attention in time: watching a movie: the physiological correlates of attention: what changes in brain activity, scene perception. How can we measure attention: perceptual thresholds: change with attention, motor accuracy, brain activity, eye movements: can reflect overt shifts of attention.
