title: Short-term memory: a brief commentary.
abstract: Over the years, a metatheoretical view of short-term memory has developed. This view, closely related to the "modal" model from the 1960s, is supported by an increasing base of neurophysiological data, and a wide variety of empirical findings. It treats short-term memory as (1) the temporary, above threshold, activation of neural structures (related in not-too-well-specified ways to various recency effects); (2) a work space for carrying out virtually all cognitive operations involved in human cognition; and (3) the source of capacity limitations, accounting for certain memory limitations and most attentional limitations. The main problem with this view is the fact that it encompasses virtually everything that we are concerned with in human cognition--a successful model would almost be a general model of cognition, something the field has not yet approached. This situation is not grounds for despair. Progress is being made on many fronts, notwithstanding the fact that the most successful models are focused on specific task domains. Recent advances include an increasing awareness of the necessity for detailed models of short-term retrieval, a theme reflected in a number of articles in the present collection.
