Decay uncovered in nonverbal short-term memory.
Decay theory posits that memory traces gradually fade away over the passage of time unless they are actively rehearsed. Much recent work exploring verbal short-term memory has challenged this theory, but there does appear to be evidence for trace decay in nonverbal auditory short-term memory. Numerous discrimination studies have reported a performance decline as the interval separating two tone...
متن کاملEvidence for temporal decay in short-term episodic memory.
In their article, ‘No temporal decay in verbal short-term memory’, Lewandowsky, Oberauer and Brown [1] omit any mention of work suggesting an important functional role for decay in episodic memory and showing that decay is detectable with sufficiently sensitive behavioral measures [2,3] (see also Refs [4–6]). The functional argument for decay is simply that interference is so potent an influenc...
متن کاملVisual memory decay is deterministic.
After observers see an object or pattern, their visual memory of what they have seen decays slowly over time. Nearly all current theories of vision assume that decay of short-term memory occurs because visual representations are progressively and randomly corrupted as time passes. We tested this assumption using psychophysical noise-masking methods, and we found that visual memory decays in a c...
متن کاملThe word-length effect provides no evidence for decay in short-term memory.
Many researchers regard the word-length effect (WLE) as one of the strongest pieces of evidence for time-based decay in short-term memory. We argue that the WLE is, in fact, undiagnostic for the decay hypothesis for two reasons. First, the WLE represents a correlation across words between articulation duration and memory performance, and articulation duration is inevitably confounded with other...
متن کاملInferring decay in short-term memory: The issue of capacity.
Experiments examining the issue of decay in short-term memory have assumed a single undifferentiated source of processing capacity which cannot be devoted to rehearsal when consumed in the processing of a nonverbal interpolated task. Three experiments reported here call this logic into question, since variations in difficulty in the nonverbal interpolated task failed to affect recall. Slight fo...
