Document Summary
Some general principles derived from studies of conditioning: cs and us intensity determine the rate and asymptote of learning, learning tends to be incremental, i. e. it accumulates with experience, learning reaches an asymptote and then stops. In 1972, robert rescorla and allan wagner attempted to integrate these principles into a comprehensive model of associative learning. We need a better description of the associative learning process . Conceptually, the rw model states that learning will continue as long as events are unexpected. Discrepancy between what is expected and what actually occurs determines the change in associative strength, i. e. this is an error correction model of learning. Relatedly, the rw model stipulates that an increase in associative strength will occur when the animal receives more than it expected, and a decrease in associative strength will occur when the animal receives less than it expected. Accordingly, excitation is represented a positive associative strength, and inhibition is represented as negative associative strength.
