Document Summary

Changed or differences in physiological responses: heart rate and eeg (electroencephalogram, we can access a baseline, see how their heart rate is when they are not looking at something we are interested in, or vice versa. Procedures for measuring infant behavior: visual tracking, high amplitude sucking, habituation procedures, preference methods. Infant is given special pacifier that responds to sucking rate. Change in sucking rate can be detected. Can access stimuli by sucking at a particular time. When you change the stimulus you can evaluate the sucking rate. Suck fast turn on a stimulation, suck slow a different sucking stimulation. Habituate infant to stimuli (by repeat exposure) Observe response: change in response (dishabituation, no change in response. Plays on the fact that we get used to certain stimulation. Infants prefer: patterns, complex patterns, moms face. Preference used to detect early learning demonstrated by high amplitude sucking. If you could suck at a different speed you could turn on different books.
