Forward pairing
CS precedes the UCS
Forward pairing (Delayed)
CS is presented before the US and it (CS) stays on until the US is presented. This is generally the best, especially when the delay is short.
Forward pairing (traced)
discrete event is presented, then the US occurs. Shorter the interval the better, but as you can tell, this approach is not very effective.
second-order conditioning
when a new CS is paired with a previously learned CS instead of an UCS during learning

Reinforcement is:
any consequence that increases the likelihood of the event occuring
Positive reinforcement
presentation of appetitive stimulus
Negative reinforcement
removal of aversive stimulus
During acquisitions of a learned response, the plateau is referred to as the
asymptope
Partial reinforcement schedules are MORE or LESS resistant to extinction over the long term?
MORE
The total number of responses an animal has made are plotted in a
cumulative record of performance
Ratio schedules give reinforcement on the basis of
responses made
interval schedules give reinforcement on the basis of
time
Variable ratio schedules produce very ________ levels of responding
high
Hebb
Neurons that fire together, WIRE together
The theory attempts to explain associative or Hebbian learning, in which simultaneous activation of cells leads to pronounced increases in synaptic strength between those cells, and provides a biological basis for errorless learning methods for education and memory rehabilitation.
Belongingness
Garcia’s term: some associations are easier to learn and others are simply impossible.
Due to biological constraints; this contradicts equipotentiality principle
