Definitions:

Simultaneous Conditioning

A classical conditioning method where both the conditioned and unconditioned stimuli are presented at the same time.

Backward Conditioning

A conditioning process where a stimulus that normally elicits a response is presented after the response, instead of before it, which can result in weakened associative learning.

Trace Conditioning

A type of classical conditioning where the conditioned stimulus (CS) and unconditioned stimulus (US) are separated by a time interval, requiring the organism to maintain a mental representation of the CS to elicit a response.

Delayed Conditioning

A classical conditioning process where the conditioned stimulus begins before the unconditioned stimulus and continues until the unconditioned stimulus starts, facilitating the association between the two.
