Learning:
ā¢A lasting change as function of experience"
ā¢Closely tied to memory"
ā¢Crucial to adapting to the environment"
Basic Types of Learning:"
1. Associative (much of our focus)"
-Involved linking two types of stimuli together"
-Example: recognizing a smell which indicates a particular food "
-Example : when you hear a song and it makes you think of a speciļ¬c moment/time
in your life"
2. Non-Associative"
-Involves one single stimulus"
-Two kinds"
1. Habituationādecrease in responding (i.e., loss of interest in a toy)"
2. Sensitizationāincrease in responding (i.e., startle to a noise)"
Key Perspectives:
ā¢Behavioral Perspective"
ā¢Cognitive Perspective"
ā¢Ecological Perspective"
Learning: Behavioral Perspective:
ā¢Classical Conditioning: ExampleāPavlovās Dogs"
-Factors aļ¬ecting Classical Conditioning:"
ā¢Timingābest when neutral stimulus
immediately precedes unconditioned stimulus"

Document Summary
Learning: a lasting change as function of experience, closely tied to memory, crucial to adapting to the environment. Basic types of learning: associative (much of our focus) Involved linking two types of stimuli together. Example: recognizing a smell which indicates a particular food. Example : when you hear a song and it makes you think of a speci c moment/time in your life: non-associative. Two kinds: habituation decrease in responding (i. e. , loss of interest in a toy, sensitization increase in responding (i. e. , startle to a noise) Key perspectives: behavioral perspective, cognitive perspective, ecological perspective. Learning: behavioral perspective: classical conditioning: example pavlov"s dogs. Factors a ecting classical conditioning: timing best when neutral stimulus immediately precedes unconditioned stimulus, stimulus generalization response to additional, similar stimuli, stimulus discrimination response to speci c stimuli and not others, extinction gradual weakening/disappearance of a conditioned response, spontaneous recovery reappearance of conditioned response, operant conditioning:
