92
Q

Negative reinforcement

A

A response is strengthened by removal or avoidance of a stimulus
-taking away annoying sound each time we ask a question would lead to us asking questions more

93
Q

positive punishment-Aversive punishment

A

a response is weakened by the presence of an unpleasant stimulus (e.g. scolding a child)

98
Q
