Working memory is a cognitive system essential to our daily life. It allows us to temporarily store information in order to perform a cognitive task. One of the main features of this type of memory is to be limited in capacity. The reasons for this limitation are widely debated in the literature. Some models consider that a main cause of forgetting in working memory is the existence of a passive temporal decay in the activation of memory representations whereas other models assume that interference between information are sufficient to explain the limited capacity of this memory. Two computational models have recently been proposed (TBRS* and SOB-CS) and they perfectly illustrate this debate. Indeed, they both describe differently what happ...
