Remembering as discrimination in delayed matching to sample: discriminability and bias.
Task difficulty in delayed matching-to-sample tasks (DMTS) is increased by increasing the length of a retention interval. When tasks become more difficult, choice behavior becomes more susceptible to bias produced by unequal reinforcer ratios. Delaying reinforcement from choice behavior also increases both task difficulty and the biasing effect of unequal reinforcer probability. Six pigeons com...
متن کاملBest matching Barenblatt profiles are delayed
The growth of the second moments of the solutions of fast diffusion equations is asymptotically governed by the behavior of self-similar solutions. However, at next order, there is a correction term which amounts to a delay depending on the nonlinearity and on a distance of the initial data to the set of self-similar Barenblatt solutions. This distance can be measured in terms of a relative ent...
متن کاملAcute and Delayed Stress Symptoms Following Snakebite
Background: Overwhelming life experiences can trigger stress disorders including acute stress disorder (ASD) and post-traumatic stress disorder (PTSD). The objective of this study was to investigate the frequency of and predictive factors for ASD and PTSD in snakebite victims. Methods: In this study, snakebite victims who were admitted to Mashhad Medical Toxicology Centre, Imam Reza Hospital, I...
متن کاملThe performance of amnesic subjects on tests of delayed matching-to-sample and delayed matching-to-position.
Forced-choice tests of recognition have become the favoured behavioural method for the assessment of models of amnesia in nonhuman primates, yet the profile of deficits shown by human amnesic subjects remains uncertain. The present study explored the performance of 12 amnesic subjects on two delayed matching-to-sample tasks. Experiment 1, which used retention delays of between 2 and 60 sec, con...
