PHYSICS 102 Lecture Notes - Lecture 12: Traumatic Brain Injury, Sensation Seeking, Human Musculoskeletal System
Document Summary
Physiological measures commonly used in personality research: electrodes: noninvasive, movement is constrained, telemetry (electrical signals are sent from one participant to the polygraph through bluetooth, wi-fi or other radio waves instead of by wires. Introverts according to this have higher levels of cortical arousal because their aras lets in too much stimulation, need to keep their already heightened level of arousal in check. Incorporated hebb"s notion of optimal level of arousal, level that is just right for any given task. Introverts are above their optimal level of arousal more often than extraverts, leads them to be more restrained and inhibited. Introverts should display enhanced responsiveness on measure of cortical activity: experiment where patients where presented with either no stimulation or very mild stimulation, differences between intro and extraverts turned out to be small or non-existent. Sensation seeking: tendency to seek out thrilling and exciting activities, take risk and avoid boredom (comes from research on sensory deprivation)
