PSYC 2000 Study Guide - Absolute Threshold, Inner Ear, Color Constancy
Document Summary
Perception- selecting, organizing, and interpreting raw sensory data into useful mental representations of the world. Sensation- receiving, converting, and transmitting information from outside world. Data goes to the brain: energy stimulates a receptor cell in a sense organ, receptor cell- specialized cell that responds to a particular type of energy, receptor sends a signal along sensory nerves the appropriate area of. Auditory- sounds, etc cerebral cortex: sensory messages enter brain on different channels, sensory thresholds, absolute thresholds- minimum intensity of physical energy required to produce any sensation at all. Taste- 1 gram of table salt in 500 liters of water, hearing- hear a ticking watch from 20 ft away: sensory adaptation- adjustment of senses to level of stimulation they are receiving. Your senses adjust to surroundings so as not to enable sensory overload. Stadium vs. library: difference threshold- aka just noticeable difference- smallest change in stimulation that you can notice 50% of the time.
