Definitions:

Delayed Conditioning

A classical conditioning process where there is a time gap between the presentation of the conditioned stimulus and the unconditioned stimulus, which can affect the strength of conditioning.

Trace Conditioning

A form of classical conditioning where the conditioned stimulus and unconditioned stimulus are presented separately with a time interval, complicating the association between them.

Backward Conditioning

A conditioning procedure where the unconditioned stimulus (US) is presented before the conditioned stimulus (CS), which is less effective than forward conditioning.

Simultaneous Conditioning

A conditioning procedure in which the conditioned stimulus (CS) and the unconditioned stimulus (US) are presented at the same time.
