Structured priors in visual working memory revealed through iterated learning
What hierarchical structures do people use to encode visual displays? We examined visual working memory’s priors for locations by asking participants to recall the locations of objects in an iterated learning task. We designed a nonparametric clustering algorithm that infers the clustering structure of objects and encodes individual items within this structure. Over many iterations, participant...
متن کاملThe Effect of Working Memory Rehabilitation on Visual Memory and Memory Span
Introduction: Age-related cognitive decline or cognitive aging is largely the result of structural and functional decline in specific areas of the brain, but lifestyle also contributes to this cognitive decline. The aim of this study was to investigate the effect of working memory rehabilitation on visual memory and memory span in ageing. Methods: This was a quasi-experimental study with pret...
متن کاملAge Differences in the Neural Representation of Working Memory Revealed by Multi-Voxel Pattern Analysis
Working memory function declines across the lifespan. Computational models of aging attribute such memory impairments to reduced distinctiveness between neural representations of different mental states in old age, a phenomenon termed dedifferentiation. These models predict that neural distinctiveness should be reduced uniformly across experimental conditions in older adults. In contrast, the C...
متن کاملRostral-caudal gradients of abstraction revealed by multi-variate pattern analysis of working memory
The lateral frontal cortex (LFC) is thought to represent contextual and rule-based information that allows adaptive behavior according to circumstance. Recent progress has suggested that the representations of the LFC vary along its rostral-caudal axis with more abstract, higher level representations associated with rostral areas of the LFC and more concrete, lower level representations associa...
