Memory length as a feedback parameter in learning systems
George Epstein · 1986
In a classic learning experiment, a higher vertebrate is presented with two levers. To start, a reward is given if the left lever is pushed, no reward is given if the right lever is pushed. After a certain period of time, T, the meaning of the two levers is interchanged. Now a reward is given if the right lever is pushed and no reward is given if the left lever is pushed. This happens for the same period of time T. Once again there is an interchange in the meaning of the two levers for the period of time T. This alternation is repeated a number of times.
