Simons, Daniel J. Ambinder, Michael Scott 2015-09-25T20:39:22Z 2015-09-25T20:39:22Z 10000-01-01 2008 2008 Current theories of the capacity of visual short-term memory postulate fixed limits on the amount of information stored in memory. Both object- and information-based accounts provide structural limitations of storage in visual memory. The current paper challenges these notions of fixed limits by providing redundant top-down information to tasks of visual memory. Neither of the current theories predicts an effect of this information on measurements of memory capacity. However, the results of these studies show that the measured capacity of visual memory can be increased through this manipulation---resulting in modifications of the extant theories to accommodate additional factors as determinants of memory capacity. The inclusion of these additional factors suggests that memory capacity should be viewed as a relative and malleable construct---shaped and determined by a variety of factors---as opposed to a single, fixed number.
