Definitions:

Classical Conditioning

A learning process that occurs when two stimuli are repeatedly paired; a response that is at first elicited by the second stimulus is eventually elicited by the first stimulus alone.

Reinforcement

In behavioral psychology, a consequence applied that will strengthen an organism's future behavior whenever that behavior is preceded by a specific antecedent stimulus.

Study Habits

Methods and practices used consistently to acquire new knowledge or skills.

Operant Conditioning

A form of learning in which a voluntary response is strengthened or weakened by its association with positive or negative consequences.
