Short-term memory is part of the system known as working memory - the mechanism by which we retain and manipulate information over short time intervals. Working memory is considered to be a fundamental cognitive process, required to perform many everyday tasks and closely correlated with intelligence.
Our research provides a fundamental challenge to conventional wisdom which considers visual working memory to be limited to a fixed number of items - just 3 or 4 - that are stored with every glimpse of the visual scene. Using precision of memory recall we have provided compelling evidence that visual working memory is not in fact ‘quantal’, but a limited resource that can be flexibly redistributed. With increasing number of items held in memory, however, the fidelity and resolution with which each object is stored declines.
