Document Summary
Human infants cannot make any verbal responses until they are about 1 year old. Visual recognition - infants look selectively at novel stimuli over familiar stimuli. Novelty preference - bias to look at things that are new. Researchers can tell when an infant remembers something, because the novelty preference will not be present. The functioning auditory system appears to support recognition of the mother"s voice, even before birth. Nonnutritive sucking - infants suck a pacifier differentially in the presence of a novel stimulus compared to a familiar stimulus; researchers measure the rate of sucking. Conjugate reinforcement technique - a ribbon is attached to the infant"s foot and eventually will be attached to a mobile placed overhead. Kicking behavior is observed to measure learning and memory. Imitation - mimicking the actions of another; can be used as a marker of memory in infants because imitation requires learning.
