Any behavior that is followed by pleasant consequences is likely to be repeated, and any behavior followed by unpleasant consequences is likely to be stopped
Edwin Guthrie’s view of Association
The simple association of an external stimulus and a behavioral response was sufficient for an animal or human subject to connect the two mentally. Only a single incident was enough for the association to be learned
