Two experiments with a working-memory updating task investigated dual-task interference between short-term storage of numerical and spatial material, between execution of a numerical and a spatial updating operation, and between storage and processing participants memorised a set of digits and a set of spatial. Working memory capacity was significantly related to overall level of correct performance on the short-term task, and to the degree of proactive interference experienced however, there was no evidence for individual differences in the ability to suppress the interfering foil, nor in priming effects associated. Both forms of external interference have been shown to detrimentally impact the ability to maintain information in working memory (wm) emerging evidence suggests that these different types of external interference exert different effects on behavior and may be mediated by distinct neural mechanisms. Abstract previous neuroimaging studies have identified brain regions that underlie verbal working memory in humans according to these studies a phonological. In some cases the interval duration can go beyond the typical interval for working memory tasks this can also have a consequence on the age effects (inman & parkinson, 1983), since it has been shown that the elderly are less impaired in long term memory recall and by long term memory interference conversely one.
These results call for a modification of the attentional allocation model to incorporate the idea of specialized processing resources two major theoretical frameworks—multiple resource theory and the working memory model—are critically evaluated with respect to the resource demands of timing and temporal/ nontemporal. Assessing the age-related effects of proactive interference on working memory tasks using the rasch model ryan p bowles and timothy a salthouse university of virginia inhibition–reduction theory (l hasher & r zacks, 1988) hypothesizes that the age-related decline in working memory (wm) span is a result of a. Of the contents of working memory from the disruptive effects of interference (eg, knight, staines, swick, & chao, 1999 postle & brush, 2004) the present article is focused on the mediation of proactive interference (pi), the deleterious effect of previously remembered in- formation on current memory representations.
The present study more directly explored the relationships among working- memory capacity, divided attention, and interference effects in memory to this end, we tested high-and low-span participants in a pi buildup and release task ( eg, craik & birtwistle, 1971 wickens, born, & allen, 1963), with half the participants. Conversely, other studies adopting similar rationale have found that cognitive load does not significantly interfere with affect recognition and support that emotion processing is automatic and independent of working memory resources [ 17,18] however, these studies have failed to control the stimulus presentation duration.
In the memory literature, both decay and interference have been proposed as causes of forgetting however research is that interference is a primary source of memory failure, affecting both the ability to maintain one of the most prominent accounts of memory function: the baddeley working memory model ( baddeley. Although the effect of working memory (wm) load on the degree of distractor processing has been investigated in a number of paradigms, a common feature in prior research is that the target and distractors pertain to different objects the present experiments examine the effect of wm load on distractor interference when the.
Also new learning can sometimes cause confusion with previous learning ( starting french may affect our memory of previously learned spanish vocabulary ) in the short term memory interference can occur in the form of distractions so that we don't get the chance to process the information properly in the first place. Visuospatial working memory is confined to the encoding phase the locus of interference in dual task, working memory experiments is typically difficult to identify for example, logie et al (1990) examined the effects of concurrent visuospatial tasks on recognition memory span for visuospatial matrix patterns the spatial.
These findings characterize spatially and temporally a proactive interference effect that may reflect the operation of a pfc-mediated response-inhibition mechanism that contributes to working memory performance substantial evidence has accumulated that the prefrontal cortex (pfc) supports a heterogeneous set of. The article introduces an interference model of working memory for information in a continuous similarity space, such as the features of visual objects similarity between target and nontarget features improves recall, and (c) precueing-but not retro-cueing-the target substantially reduces the set-size effect. 1990 keppel and underwood 1962) interference from prior memories, whether these are stored in long-term or short-term (working) memory, is referred to as proactive interference (pi) for instance, the memory trace of a previously encoded word or an image may affect the ability to recollect another word.
