Definitions:

Trial And Error

A problem-solving method that involves attempting different solutions and eliminating those that fail to solve the problem until the correct one is found.

Latent Learning

Learning that occurs without any obvious reinforcement or immediate demonstration of understanding, becoming apparent only when it is needed.

Classical Conditioning

An associative learning process where the consistent pairing of two stimuli facilitates a response that initially originates from the second stimulus but later originates from the first stimulus alone.

Insight Learning

A form of problem-solving that occurs when a solution is suddenly realized after a period of reflection, rather than through trial and error.
