Focal Abnormality

Memory capacity depends on prior knowledge, both in working memory and in long-term memory. For example, radiologists have improved long-term memory for medical images compared to novices. Furthermore, people tend to remember abnormal or surprising items best. This is often claimed to arise primarily because such items attract additional attention at encoding. How do expertise and abnormality interact when experts are actively searching for abnormalities; e.g. radiologists looking at mammograms? In the current work, we investigate whether expert radiologists (N=32) show improved memory performance for abnormal images compared to novice participants (N=60). We consider two types of “abnormality.” A mammogram can have a focal abnormality that can be localized or it could simply be the mammogram of a woman known to have cancer (e.g. the image of the breast contralateral to the focal abnormality). Must an image have a focal abnormality for additional attentional processing to be engaged? We found that experts have better memory for mammograms than novice participants and enhanced memory for abnormal images relative to normal images. Overall, radiologists showed no memory benefit for the contralateral-abnormal images and did not discriminate them from normal images, but had enhanced memory for images with focal abnormalities. Our results suggest that focal abnormalities play an important role in enhancing memory of expert observers.

This chapter reviews evidence from behavioural and cognitive neuroscience research that supports a unitary view of memory whereby working memory and long-term memory phenomena arise from representations and processes that are largely shared when remembering over the short or long term. Using ‘false working memories’ as a case study, it highlights several paradoxes that cannot be explained by a multisystem view of memory in which working memory and long-term memory are structurally distinct. Instead, it is posited that behavioural memory effects over the short and long term relating to semantic processing, modality/domain-specificity, dual-task interference, strategic processing, and so on arise from the differences in activational states and availability of different representational features (e.g. sensory/perceptual, associative, action-based) that vary in their time courses and activity, attentional priority, and susceptibility to interference. Cognitive neuroscience evidence primarily from brain imaging methodologies that support this view is reviewed.

Short And Long Term

Declines in both short and long-term memory are typical of healthy aging. Recent findings suggest that retrospective attentional cues ("retro-cues") that indicate the location of to-be-probed items enhance both short (STM) and long-term memory (LTM) performance in young adults. Whether older adults can also use retro-cues to facilitate both STM and LTM memory is unknown.Young and older adults performed a visual STM task in which spatially informative retro-cues or non-informative neutral-cues were presented during STM maintenance of real-world objects. We tested participants' memory for retro-cued and neutral-cued objects at both at short and long delays in order to measure the effect of retrospective attention on STM and LTM. Older adults showed reduced STM and LTM capacity compared to young adults. However, they showed similar magnitude retro-cue memory benefits as young adults at both STM and LTM delays. To the best of our knowledge, this is the first study to investigate whether retro-cues improve both STM and LTM in older adults. Our results support the idea that retrospective attention can be an effective means by which older adults can improve their short and long-term memory performance, even in the context of reduced memory capacity.

Hebb Repetition Effect

In tests of working memory with verbal or spatial materials repeating the same memory sets across trials leads to improved memory performance. This well-established “Hebb repetition effect” could not be shown for visual materials. This absence of the Hebb effect can be explained in two ways: Either persons fail to acquire a long-term memory representation of the repeated memory sets, or they acquire such long-term memory representations, but fail to use them during the working memory task. In two experiments, (N1 = 18 and N2 = 30), we aimed to decide between these two possibilities by manipulating the long-term memory knowledge of some of the memory sets used in a change-detection task. Before the change-detection test, participants learned three arrays of colors to criterion. The subsequent change-detection test contained both previously learned and new color arrays. Change detection performance was better on previously learned compared to new arrays, showing that long-term memory is used in change detection.

Span Tasks

Individual differences in working memory have been related to interactions between working memory and long-term memory (LTM). The present study examined this interaction in children with and without language impairment. We used two listening span tasks and two nonword repetition tasks. The results suggest a strong interaction among age, language status, and task complexity. Children with specific language impairment showed consistently poor performance across tasks and indicated a weakness in using long-term knowledge to support working memory performance. The findings show that these children do not benefit from various manipulations designed to enhance working memory performance via LTM support due to a combination of inefficiencies in maintaining and updating items in working memory and retrieving information from LTM, in part because of their poor resistance to interference.

Abstract The different environmental conditions in which people live might challenge memory in different ways. Moreover, the frequency of usage can be a source of improvement of both short- and long-term memory. The aim of our study was to investigate the effects of environmental differences on short- and long-term memory in a traditional versus a contemporary population (Dani of Papua, n = 62; Polish, n = 134). We found that both short- and long-term memory varied in the two populations, living in totally distinct surroundings. However, there were no age differences between Polish and Dani participants in either short- or long-term memory tasks, indicating that culture was not a significant moderator of the memory differences between populations. The differences in short- and long-term memory between the two populations are consistent with the argument that short-term memory plays a more significant role in contemporary societies because of technical developments, the electronic revolution, and reading ability. The lack of an age difference appears to support the assumption that it is age, not culture, that plays a crucial role in the memory performance.
