Item and Associative Interactions in Short-term Memory: Multiple Memory Systems?

Three interactions of item and associative information are discussed: differential forgetting (item recognition declines over lag ranges where pair recognition does not; Hockley, 1991); differential emphasis (instructions to attend to items degrade later pair recognition but instructions to attend to pairs does not degrade later item recognition; Hockley & Cristi, 1996a), and multiple presentations of pairs or items from pairs has little effect on judgements of frequency of items and pairs (Hockley & Cristi, 1996b). Taken as a whole, these results seem to be inconsistent with a separate memory-systems view of memory. TODAM, a global-matching model, has always assumed a single memory system for the storage and retrieval of item and associative information and, with the addition of context and mediators, it can generate the whole pattern of data.     

Skills and Knowledge - Nothing but Memory?

The aim of this article is to enquire into neuroscientific research on memory and relate it to topics of skill, knowledge and consciousness. The article outlines some contemporary theories on procedural and working memory, and discusses what contributions they give to sport science and philosophy of sport. It is argued that memory research gives important insights to the neuronal structures and events involved in knowledge and consciousness contributing to sport skills, but that these explanations are not exhaustive. The article argues that phenomenal consciousness in skills is not explained by the neuroscience of memory, and hence neither are skills.     

Imagery and Recognition: Dissociable Measures of Memory?

An assumption of many theories of visual cognition is that imagery tasks and picture recognition tasks tap the same kind of memory processes (i.e. visual), implying that these two types of tests can be used as interchangeable measures of visual memory. In this paper, we investigated whether articulatory suppression—a variable known to improve imagery performance—has a similar effect on picture recognition performance. In Experiment 1, subjects performed either an imagery task or a recognition task while engaging or not in articulatory suppression; in Experiment 2, the same subjects performed first the imagery task, and then the recognition task, while engaging or not in articulatory suppression. When the type of task was manipulated between subjects (Experiment 1), imagery performance was significantly improved by articulatory suppression. In contrast, recognition performance was significantly impaired by the introduction of articulatory suppression. In accordance with results of Experiment 1, in Experiment 2 imagery and recognition performance were found to be unrelated. However, when the same subjects performed both tasks, the opposite effect of articulatory suppression on imagery vs recognition performance was observed only on the first item. It does appear that when the imagery task and the picture recognition task are performed in isolation, performance is found to be independent, suggesting that the two tasks are mediated by different mechanisms. However, when a within-subjects design is used, performance in one task can be contaminated by the presence of the other task.     

Memory Development or the Development of Memory?

For 30 years, the question "What is memory development the development of?" has guided research on children's memory. As theories and research paradigms have evolved over this period, so too has knowledge of the surprising mnemonic competence of young children and of age-related differences in memory performance. Never the less, there are serious limits to current understanding of the development of memory. Indeed, there have been few investigations of changes over time in the memory skills of individual children, and researchers have yet to shed much light on the more difficult question of "What are the forces that propel the development of skilled remembering?" From our perspective, the answer to this question will require movement toward longitudinal research designs that illuminate the mechanisms that bring about developmental change.     

Remote Memory Function and Dysfunction in Korsakoff’s Syndrome

Korsakoff's syndrome (KS) is a pervasive disorder of memory characterized by both anterograde and retrograde amnesia. Although retrograde memory impairment in KS has been less frequently studied, the status of remote memory in KS has been tested across a number of different tasks that measure knowledge of public information (e.g., famous faces/news events), general semantic information (e.g., vocabulary words), personal semantic information (e.g., facts about oneself), and autobiographical events (e.g., events from one's personal past). In each of these domains, Korsakoff patients demonstrate remote memory impairments that can extend back many years or decades. In addition, a majority of studies report that the extensive remote memory impairment in KS is temporally graded, with relative preservation of memories from childhood and early adulthood. The current paper reviews published experimental studies of remote memory in KS, with particular attention paid to (a) the selectivity of the deficit with respect to the age of the memory and (b) the relationship of memory impairment to underlying neuropathology. We discuss the significance of the reported pattern and extent of remote memory impairment with respect to theories about the nature of the underlying cognitive deficits in KS.     

Working Memory and Learning in Early Alzheimer’s Disease

Cognitive deficits associated with early Alzheimers disease (AD) have been recently operationalised in terms of an acquisition deficit and the research supporting this view is presented. However, there is still debate concerning the nature of this deficit and how underlying cognitive processes may be detrimentally affecting the ability to acquire new information in early AD. This review argues that the pattern of cognitive deficits contributing to the acquisition impairment in early AD patients may be readily interpreted within the context of a working memory model. Isolating the component processes of working memory that underlie the acquisition deficit in early AD patients will aid in the design of clinical applications that are focussed at enhancing the ability to acquire new information in everyday life.     

Spinoza’s error: Memory for truth and falsity

Two theoretical frameworks have been proposed to account for the representation of truth and falsity in human memory: the Cartesian model and the Spinozan model. Both models presume that during information processing a mental representation of the information is stored along with a tag indicating its truth value. However, the two models disagree on the nature of these tags. According to the Cartesian model, true information receives a “true” tag and false information receives a “false” tag. In contrast, the Spinozan model claims that only false information receives a “false” tag, whereas untagged information is automatically accepted as true. To test the Cartesian and Spinozan models, we conducted two source memory experiments in which participants studied true and false trivia statements from three different sources differing in credibility (i.e., presenting 100% true, 50% true and 50% false, or 100% false statements). In Experiment 1, half of the participants were informed about the source credibility prior to the study phase. As compared to a control group, this precue group showed improved source memory for both true and false statements, but not for statements with an uncertain validity status. Moreover, memory did not differ for truth and falsity in the precue group. As Experiment 2 revealed, this finding is replicated even when using a 1-week rather than a 20-min retention interval between study and test phases. The results of both experiments clearly contradict the Spinozan model but can be explained in terms of the Cartesian model.     

Memory monitoring and memory performance: Linked closely or loosely?

Summary An experimental test of the metamemory hypothesis claiming a substantive positive relationship between memory monitoring and memory performance is provided. Forty-eight university students learned a set of abstract nouns. They were either instructed to make use of monitoring activities (experimental group), simply to learn the words (control-1) or to use non-metacognitive learning strategies (control-2). Prior to recall, the subjects had to predict the number of items they expected to remember. The experimental predictions were derived on two levels. First, prediction accuracy should be best for the experimental group. This is a necessary prerequisite for a valid test of the second prediction, namely that memory performance, too, should be best for the experimental group. Whereas the first prediction was confirmed, the second, vital for the metamemory hypothesis, was not. Thus, this hypothesis did not stand up to an experimental test, but would have been confirmed if tested by the correlation between prediction accuracy and memory performance.     

On ‘Doing’ Memory and Self in Different Cultural Contexts

After a brief and pointed recapitulation of the main issues of Demuth, Chaudhary and Keller’s article, Memories of me. Comparisons from Osnabrück (Germany) and Delhi (India) students and their mothers (doi:), alternative or complementary approaches to the investigation of ‘doing’ memory and self in different cultural contexts are outlined in a sketch of three interrelated proposals. These proposals turn around a) ‘contemporaneousness of the non-contemporaneous’ (Gleichzeitigkeit des Ungleichzeitigen) and the analysis of ‘cultural hybrids’, b) ‘indigenous concepts of memory and self’ and c) ‘memory and self in actual cultural practice’.     

Memory cueing and instructional effects on Wason’s selection task

The present study examined the hypothesis that violation and role-playing instructions are necessary conditions for facilitation on Wason’s selection task and that facilitation due to memory cueing via thematic content is secondary. The results of a factorial experiment employing these factors did not support the hypothesis. Memory cueing was indicated as the primary factor, but violation instructions did increase the amount of facilitation observed. This interactive effect and the nature of facilitation by memory cueing are briefly discussed.     

Short-Term Memory and Working Memory in Children with Blindness: Support for a Domain General or Domain Specific System?

The study explored the contribution of two component processes (phonological and executive) to blind children's memory performance. Children with blindness and sight were matched on gender, chronological age, and verbal intelligence and compared on measures of short-term memory (STM) and working memory (WM). Although the measures were highly correlated, the results from two experiments indicated that the blind children were superior to sighted children on measures of STM, but not on measures of WM. The results supported the notion that children with blindness have advantages on memory tasks that draw upon resources from the phonological loop. However, comparable performance between the ability groups on WM measures suggests there are domain specific aspects in the executive system.     

The Wechsler Memory Scale—Revised: Psychometric characteristics and clinical application

The psychometric characteristics of the Wechsler Memory Scale—Revised (WMS-R) are evaluated and related to dits clinical utility. The accuracy of the scale scores is shown to be limited by their high standard error, low reliabilities, and consequent large standard errors of measurement. Specific procedures are discussed for establishing confidence intervals and for testing the significance of differences between scores. It is concluded that the WMS-R, like the original Wechsler Memory Scale, provides only a rough estimate of overall memory functioning. The multidimensional index scores have not been shown effective in describing the nature or the pattern of memory deficits. Recommendations for the clinical use of the WMS-R are provided.     

Memory,Rite, and Tradition： A Comparative Confucian-Christian Literary Analysis

I The Confucian Classics and Christian Scriptures speak often about the role ＂the past＂ plays in shaping individual and communal character, life, perception, morality and purpose. In both Christianity and classical Confucianism, memory, rite and tradition are each accorded a central place in preserving and interpreting the past as a dynamic force in the present. The first part of this paper studies points of thematic similarity in Christian and Confucian interpretation of memory, rite and tradition. In the second part of the paper, however, critical points of divergence are addressed; for behind the formal similarities lie deeper intellectual, relational and moral differences in understanding the nature and function of ＂the past＂ in determining both the present and the future. Comparative literary analysis provides a rich resource for contemporary application of the Confucian Classics and Christian Scriptures to discussion of cultural memory and global harmony. The comparative reading of ＇texts＇ also provides an important point of access for understanding the role literature itself plays in determining the form, content and power of memory, ritual and tradition in both Confucianism and Christianity.     

What Part of Working Memory is not Working in ADHD? Short-Term Memory, the Central Executive and Effects of Reinforcement

Deficits in Working Memory (WM) are related to symptoms of Attention-Deficit/Hyperactivity Disorder (ADHD). In children with ADHD visuospatial WM is most impaired. WM is composed of Short-Term Memory (STM) and a Central Executive (CE). Therefore, deficits in either or both STM and the CE may account for WM impairments in children with ADHD. WM-component studies investigating this find deficits in both STM and the CE. However, recent studies show that not only cognitive deficits, but also motivational deficits give rise to the aberrant WM performance of children with ADHD. To date, the influence of these motivational deficits on the components of WM has not been investigated. This study examined the effects of a standard (feedback-only) and a high level of reinforcement (feedback + 10 euros) on the visuospatial WM-, visuospatial STM-, and the CE performance of 86 children with ADHD and 62 typically-developing controls. With standard reinforcement the STM, CE, and WM performance of children with ADHD was worse than that of controls. High reinforcement improved STM and WM performance more in children with ADHD than in controls, but was unable to normalize their performance. High reinforcement did not appear to improve the CE-related performance of children with ADHD and controls. Motivational deficits have a detrimental effect on both the visuospatial WM performance and the STM performance of children with ADHD. Aside from motivational deficits, both the visuospatial STM and the CE of children with ADHD are impaired, and give rise to their deficits in visuospatial WM.     

Memory and identity among post-Soviet Evangelical Christians–Baptists in contemporary Ukraine

Evangelical Christians–Baptists (ECBs) are a prominent denomination in contemporary Ukraine. They survived persecution by Soviet state atheism and are meeting the challenges of postcommunist freedom. They provide good ground for a case study on how religious communities preserve their collective memories and identities when times and conditions change. In this paper, based on various sources produced by churches and religious organisations, I analyse the ways in which ECBs maintain and reflect upon their collective memories and reinvent their traditions. Particularly I focus on historical narratives and commemorations. I argue that the ECBs develop their collective memories in transnational, local and personal perspectives. They are eager to see the history of their community as an inalienable part of the national history of Ukraine, but also consider themselves as both rooted in Russian culture and heirs of a European Protestant tradition. The main values in the core of their memory discourse are holiness, spirituality, suffering for faith and survival of the community in a hostile society. Celebrations of faith heroes and martyrs are especially popular among those who belong to the former underground wing of this denomination. A more recent trend is the celebration of the history of local congregations. As ECBs perceive threats to their traditional way of life from the West and the national liberalism of today, they become more fundamentalist and persistent in its preservation and protection. Ultimately, in order to defend their cultural space from ‘immoral’ influences, they have become more politically active and have contributed to conservative and anti-liberal agendas on the national level in Ukraine.

Children and the Test of Memory Malingering: Is one trial enough?

There is a growing body of research suggesting that the first trial of the TOMM may provide an accurate screener of effort in children. During neuropsychological assessments, some circumstances result in only one completed trial of the TOMM. Research on adults reflects that passing scores on Trial 1 (based on Trial 2 cutoff) are highly predictive of passing scores on Trial 2 and the TOMM overall. Pediatric research found that 100% of children and adolescents who passed Trial 1 of the TOMM also passed Trial 2. Our research hypothesis is that children who pass Trial 1 will also pass Trial 2. Data from 75 clinically diagnosed children (ages 6–18 years) found that 64% performed above the published adult TOMM cutoff on Trial 1. All children who passed Trial 1 also passed Trial 2 suggesting support for the research hypothesis. Sensitivity was 1.0, specificity was 0.72, positive predictive value was .33, and negative predictive value was 1.0. These findings suggest that in this sample, the children who performed above the Trial 2 cutoff on Trial 1 also all passed Trial 2 (so there were no false negatives, thus a perfect sensitivity and negative predictive value). Of the 36% of children who did not pass the Trial 1 cutoff, 67% passed on Trial 2. Data clearly support that children passing Trial 1 have a high likelihood of passing Trial 2, thus drawing conclusions about performance validity after passing Trial 1. Conclusions after failing Trial 1 require further investigation.
