Associative Learning Through Acquired Salience

Most associative learning studies describe the salience of stimuli as a fixed learning-rate parameter. Presumptive saliency signals, however, have also been linked to motivational and attentional processes. An interesting possibility, therefore, is that discriminative stimuli could also acquire salience as they become powerful predictors of outcomes. To explore this idea, we first characterized...

Relative salience versus relative validity: cue salience influences blocking in human associative learning.

Two studies of human contingency learning investigated the influence of stimulus salience on the cue competition effect of blocking. These studies demonstrated that blocking (defined as a difference in responding to blocked and control cues) was greater for target cues that had high "semantic salience" than those of lower salience. Moreover participants showed weaker responding to high salience...

Attention and salience in associative blocking.

The associative learning effect called blocking has previously been found in many cue-competition paradigms where all cues are of equal salience. Previous research by Hall, Mackintosh, Goodall,and dal Martello (1977) found that, in animals, salient cues were less likely to be blocked. Crucially, they also found that when the to-be-blocked cue was highly salient, the blocking cue would lose some...

Awake, Offline Processing during Associative Learning

Offline processing has been shown to strengthen memory traces and enhance learning in the absence of conscious rehearsal or awareness. Here we evaluate whether a brief, two-minute offline processing period can boost associative learning and test a memory reactivation account for these offline processing effects. After encoding paired associates, subjects either completed a distractor task for t...

Circuits and Expressions with NOn-Associative Gates

We consider circuits and expressions whose gates carry out multiplication in a non associative algebra such as a quasigroup or loop We de ne a class we call the polyabelian algebras formed by iterated quasidirect products of Abelian groups We show that a quasigroup can express arbitrary Boolean functions if and only if it is not polyabelian in which case its Expression Evaluation and Circuit Va...
