Document Summary

Infants fixate a green square less after habituating to a green triangle than after habituating to a red triangle. *sucking can also be measured; higher frequency of sucking means they want to keep the object visible for longer. When they have habituated, the amplitude of sucking decreases drastically. *pair the conditioned stimulus and unconditioned stimulus to create a conditioned response. *omitting an aversive us (noise) produces heart-rate acceleration (protective) *omitting an appetitive us (sucrose) produces heart-rate deceleration (where is it?) *smiling was tested to see if infants responded to timetables. *partial reinforcement group had a higher response rate. Deferred imitation: infants observe a sequence of target. Infants who say the original demonstration for 30 seconds exhibited deferred imitation 7 days later. Sensory preconditioning: an association is formed between 2 stimuli or events that occur together such that what is eventually learned about one of them generalizes to the other: s1 and s2 are paired, s1=r1, s2=r1.
