Working-memory capacity protects model-based learning from stress.
Accounts of decision-making have long posited the operation of separate, competing valuation systems in the control of choice behavior. Recent theoretical and experimental advances suggest that this classic distinction between habitual and goal-directed (or more generally, automatic and controlled) choice may arise from two computational strategies for reinforcement learning, called model-free ...
متن کاملThe Effect of Working Memory Training on Working Memory Capacity and Performance of Novice Karateka
Objective: This study aimed to investigate the effect of working memory (WM) training on WM capacity and performance of novice karate practitioners (karateka). Methods: Research method is quasi-experimental with a pretest posttest control group design. A total of 24 karate practitioners were selected among Alborz (Alborz Province, iran) novice karateka by convenience sampling me...
متن کاملA working memory model based on fast Hebbian learning.
Recent models of the oculomotor delayed response task have been based on the assumption that working memory is stored as a persistent activity state (a 'bump' state). The delay activity is maintained by a finely tuned synaptic weight matrix producing a line attractor. Here we present an alternative hypothesis, that fast Hebbian synaptic plasticity is the mechanism underlying working memory. A c...
متن کاملWorking Memory Capacity Limits Motor Learning When Implementing Multiple Instructions
Although it is generally accepted that certain practice conditions can place large demands on working memory (WM) when performing and learning a motor skill, the influence that WM capacity has on the acquisition of motor skills remains unsubstantiated. This study examined the role of WM capacity in a motor skill practice context that promoted WM involvement through the provision of explicit ins...
متن کاملHow working memory capacity constrains the learning of relational concepts
We investigated the way in which working memory (WM) constrains the learning of relational concepts – categories defined by the way objects are assigned to roles in the structure of an underlying relation, and not by objects’ intrinsic features. By applying to a large sample a novel test of concept learning as well as the battery of WM tasks, we found that WM is a strong predictor of the scores...
