Before revision:  To answer this question and understand post-acquisition behavior and its related individual differences, we propose a psychological principle that naturally extends the basic associative single-cue Rescorla-Wagner model (which may also be called Hull model) of Pavlovian conditioning to (i) a framework of dynamical models predicting resistance to learning in the first few sessions followed by an over-optimal response peak . In turn, (ii) the theory can be further extended to describe response fluctuations by the laws of quantum mechanics. (iii) We also introduce an independent model characterized by the presence of a stochastic noise of cognitive origin .
After revision:  To answer this question and understand post-acquisition behavior and its related individual differences, we propose a psychological principle that naturally extends the basic associative single-cue Rescorla-Wagner model (which may also be called Hull model) of Pavlovian conditioning to (i) a framework of dynamical models predicting resistance to learning in the first few sessions followed by an over-optimal response peak and a sequence of progressively damped response oscillations. We detected the first peak and trough of the new learning curve in our data, but their dispersion was too large to also check the presence of a stochastic noise of cognitive origin .
