Learning is defined as a relatively permanent change in behavior resulting from practice or experience. Key elements include behavior demonstration, lasting change, and the significant brain alterations that occur. Learning is influenced by stimuli, which provoke responses from organisms, as illustrated by Pavlov's classical conditioning. In his experiments, unconditioned responses occur naturally, while conditioned responses develop through repeated pairing of stimuli. The effectiveness of conditioning increases with more repetitions and optimal intervals. Explore how learning shapes our behaviors through these foundational concepts.

Learning A relatively permanent change in behavior that results from practice or experience.
4 key elements to learning • BEHAVIOR • Demonstrate the learning • CHANGE • The brain is altered • PERMANANCE • The behavior is retained • PRACTICE/EXPERIENCE • Are both ways to effect change
STIMULUS: A stimulus is something that produces activity in an organism. • Touch • Sound • Smell RESPONSE: • A response is the reaction of a organism to a stimulus.
Ivan Pavlov and Classic Conditioning Natural Response Unconditioned Response-UCR no training necessary, involuntary (salivation) Unconditioned Stimulus-UCS The thing that produces the UCR (the food)
Conditioned Response Conditioned Response-CR dog salivates (to the bell) Conditioned Stimulus-CS sound that caused the response (the bell)
Repetition: the treatment must be repeated. More repetitions makes for a stronger association. • Interval: • Time between treatments . Pavlov found that .5 seconds was the best interval.
