Emit, Evoke, Elicit

Emit

operant behavior/conditioning voluntary and can be consciously stopped (e.g. a mouse hitting a lever in order to receive a food pellet)

elicit

Produce as an invariable result. A puff of air on the eye elicits an eye blink. The term elicit refers to reflexes where the unconditioned response bears a one-to-one relationship to the unconditioned stimulus

Emit

Produce, but not as an invariable result of any particular stimulus. A student in a class emits many responses which are not an automatic response to any preceding stimuli. A term that describes the occurrence of operant behavior. In this text, familiar verbs such as express, perform, respond, and behave are used as equivalents.

Evoke

The production of a response. A response is sometimes said to be evoked if it is unclear whether it is emitted or elicited

Elicit

classical conditioning responses that are reflexive and involuntary (e.g. salivary response of a dog is elicited by meat powder)
