Many researchers regard the word-length effect (WLE) as one of the strongest pieces of evidence for timebased 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 word characteristics. Recent research has confirmed that such confounds are responsible for much… Expand

Topics from this paper

When does length cause the word length effect?
TLDR
It is suggested that the word length effect may be better explained by the differences in linguistic and lexical properties of short and long words rather than by length per se. Expand
Does neighborhood size really cause the word length effect?
TLDR
In six experiments, the hypothesis that the previous abolition of the word length effect when neighborhood size was controlled was due to a confounded factor: frequency of orthographic structure was tested and the results were not consistent with the predictions of Jalbert et al. and clearly showed a large and reliableword length effect after controlling for neighborhood size. Expand
In search of decay in verbal short-term memory.
TLDR
The results of these studies indicate that short-term memories are subject to very small decay effects with the mere passage of time but that interference plays a much larger role in their degradation. Expand
Two Systems of Maintenance in Verbal Working Memory: Evidence from the Word Length Effect
TLDR
The present study re-evaluated the WLE in a complex span task while controlling for time parameters and the amount of concurrent articulation and found that the existence of two systems of maintenance for verbal information is supported. Expand
Retroactive interference in short-term memory and the word-length effect.

TLDR
This study shows that long words produce more retroactive interference than short words, supporting an interference-based account for the word-length effect. Expand
Reconsidering the two-second decay hypothesis in verbal working memory
Abstract A common belief in the study of short-term memory is that the verbal trace decays around two seconds after it is encoded. This belief is typically assumed to follow from the finding that inExpand
Decay uncovered in nonverbal short-term memory
TLDR
It appears that the mere passage of time can lead to forgetting in some forms of short-term memory, as slow-acting trace decay was observed. Expand
Do familiar memory items decay?
TLDR
The findings suggest that time-based forgetting is persistent across all of these factors while simultaneously challenging prominent views of trace decay. Expand
Interpreting potential markers of storage and rehearsal: Implications for studies of verbal short-term memory and neuropsychological cases
TLDR
It is indicated that the absolute magnitude of phonological similarity and word length effects depends on overall levels of recall, and that these effects are necessarily eliminated at low levels of verbal short-term memory performance. Expand
Memory, Interference and Depression.
Is forgetting in the short-term due to decay with the mere passage of time, interference from other memoranda, or both? Past research on short-term memory (STM) has revealed some evidence for decayExpand

There Are Two Word-Length Effects in Verbal Short-Term Memory: Opposed Effects of Duration and Complexity
In the word-length effect (WLE), lists of shorter words are better recalled than lists of longer words This effect is fundamental to decay-based theories of verbal short-term memory, such as theExpand
Word-length effects in immediate memory: Overwriting trace decay theory
TLDR
It is argued that word-length effects do not offer sufficient justification for including time-based decay components in theories of memory, and an extension of Nairne’s (1990) feature model is used. Expand
Is There a Temporal Basis of the Word Length Effect? A Response to Service (1998)
TLDR
It is concluded that both duration and complexity are likely to contribute to the word length effect in serial recall. Expand
Word length and the structure of short-term memory
A number of experiments explored the hypothesis that immediate memory span is not constant, but varies with the length of the words to be recalled. Results showed: (1) Memory span is inverselyExpand
The role of verbal output time in the effects of word length on immediate memory.
In three experiments, we examined the role of delays within overt verbal responding in causing effects of word length on immediate recall. Although a phonological memory decay mechanism has beenExpand

TLDR
It is suggested that either memory search or rehearsal processes (or both) can be used to refresh items in a list and that search processes would tend to be used when there is a strong lexical representation of each word, so that recall of the word is an all-or-none event. Expand
