The safety-efficiency dilemma describes the problem of maintaining safety during efficient exploration and is a special case exploration-exploitation in face potential dangers. Conventional solutions collapse punishment reward into single feedback signal, whereby early losses can be overcome by later gains. However, brain has separate system for Pavlovian fear learning, suggesting possible computational advantage to specific memory exploratory decision-making. In series simulations, we show this promotes safe but learning optimised arbitrating avoidance instrumental decision-making according uncertainty. We provide basic test model simple human approach-withdrawal experiment, that flexible captures choice reaction times. These results more sophisticated role than previously thought, shaping behaviour computationally precise manner.

The ABA renewal effect occurs when behavior is trained in one context (A), extinguished a second (B), and the test training (A).Two mechanisms that explain are summation at contextual modulation of extinction learning, with former being unlikely if both contexts have similar associative history.In two experiments, we used within-subjects designs which participants learned to avoid loud noise (unconditioned stimulus) signaled by discrete visual stimuli (conditioned [CSs]), pressing space bar on computer keyboard.The was conducted contexts, different pair CSs (CS+ CS-) each context.During extinction, CS+ CS-stimuli were presented alternative from training, allowed freely respond, but no presented.Finally, all tested resulting versus ABB comparison.Across increased avoidance responses during decreased them although Experiment 2 revealed less extinction.During test, responding higher (ABA) (ABB), revealing instrumental avoidance.Experiment also measured expectancy after remarkable similarity between ratings.This study shows humans, results suggest operation modulatory role for renewal, occasion setting learning context.
