Study Notes
- Short-term memory (STM) refers to the temporary storage of relatively small amounts of information.
- Early approaches to STM involved the digit span and related sequential verbal tasks.
- The concept of a phonological loop explains verbal STM by assuming a temporary store and an articulatory rehearsal process.
- Inherent in the memory span task is the problem of serial order and how it is maintained, a problem that has led to a number of detailed models.
- Free recall typically shows a marked recency effect, which has resulted in a number of influential models applied to both STM and LTM.
- Most current studies of visual STM focus on simple stimuli such as colors and shapes and the question of how these are bound into unified colored shapes.
- Spatial STM is separable from its visual equivalent and depends on somewhat different neural systems.
- Laboratory studies of both verbal and visual STM have been extended and enriched by studies of patients with STM deficits.
