Associative learning is an essential feature of human cognition, accounting for the influence of priming and interference effects on memory recall. Here, we extend our account of associative learning that learns asymmetric item-to-item associations over time via experience by including link maturation to balance associations between longer-term stability while still accounting for short-term variability. This account, combined with an existing account of activation strengthening and decay, predicts both human response times and error rates for the fan effect for both target (...) and foil stimuli.

I argue in favor of a certain connection between knowledge and the permissibility of action. On this approach, we do not think of the relation between those notions as reflecting a universal epistemic principle. Instead, we think of it as something resembling a platitude from folk psychology. With the help of some elementary tools from the logic of normativity and counterfactuals, I attempt to establish the connection by deriving it from more elementary principles. The new formulation involves a ceteris paribus (...) clause. Though it is often difficult to specify the exact content of a ceteris paribus clause, we will see that our clause is derived from a descriptive generalization with independent motivation. (shrink)
