— In classical conditioning
, a form of internal inhibition
, in which the positive conditioned stimulus
is temporarily transformed into a negative or inhibitory
response, by the simple method of repeating it several times in succession without reinforcement.
- Dog is conditioned to associate bell with food.
- Dog salivates at bell
- This happens a few times, but no food arrives.
- Dog stops salivating when the bell rings.

Expectation and Disappointment
An association has been taught. That is, a conditioned response (CR
) has been produced in the learner. When the conditioned stimulus appears, there is an expectation
that the unconditioned stimulus (US
, usually something rewarding) is about to occur. In an ANN
one should be able to produce a signal that represents expectation. That is, after the CS
occurs and before the UR
occurs. In Netlab, this signal can even be set to increase with the passage of time sans UR
Expectation unmet: (disappointment?)
If the expectation is not met after a certain amount of time passes, a disappointment signal should begin to ramp up. Disappointment may be a bad name for this phase,
since, if the US
is noxious (i.e., conditioned avoidance
), the response will not be disappointment (relief? hopefulness? joy?).
