PSYC 2000 Chapter : SI Session - Chapter 3
Document Summary
Supplemental instruction: chapter 3: increased heart rate, pupil constriction, slowed breathing, increased digestion, gaba, dopamine, serotonin, acetylcholine (most common inhibitory nt sleep, inhibition of movement) Warmup: sara has been experiencing a serious memory problem. An interdisciplinary team has ruled out a range of causes and believes that a neurotransmitter is involved. Activity 1: sensation: frontal lobes, temporal lobes, occipital lobes, parietal lobes, eeg, deep lesioning, ct scan, pet scan. Made up of sensory receptors that convert stimuli to neural activity. Transduction: conversion of outside stimuli into a neural signal in the brain. The smallest difference between two stimuli that is detectable 50% of the time. The smallest amount of energy needed for a person to consciously detect a stimulus 50% of the time. Think about subliminal stimuli, habituation, and sensory adaptation. Habituation: tendency of the brain to stop attending to constant, unchanging information (brain ignores unchanging stimuli)
