Is music a memory booster in normal aging? The influence of emotion

Age-related differences in episodic memory have been explained by a decrement in strategic encoding implementation. It has been shown in clinical populations that music can be used during the encoding stage as a mnemonic strategy to learn verbal information. The effectiveness of this strategy remains equivocal in older adults (OA). Furthermore, the impact of the emotional valence of the music used has never been investigated in this context. Thirty OA and 24 young adults (YA) learned texts that were either set to music that was positively or negatively valenced, or spoken only. Immediate and delayed recalls were measured. Results showed that: (i) OA perform worse than YA in immediate and delayed recall; (ii) sung lyrics are better remembered than spoken ones in OA, but only when the associated music is positively-valenced; (iii) this pattern is observed regardless the retention delay. These findings support the benefit of a musical encoding on verbal learning in healthy OA and are consistent with the positivity effect classically reported in normal aging. Added to the potential applications in daily life, the results are discussed with respect to the theoretical hypotheses of the mechanisms underlying the advantage of musical encoding.     

The origins of the synagogue in past and present research – some comments on definitions,theories, and sources

The idea that the synagogue originated in the Babylonian exile has been so frequently repeated over the centuries that, despite the fact that this consensus broke down over 20 years ago, some researchers still quote it as if it were an incontestable historical fact. The present study analyses the history of scholarship on the origins of the synagogue, from the first century writings of Philo to the recent work of Lee Levine. Challenging old assumptions and ideas, it takes a new approach to the study of the synagogue and proposes a radical solution to this ancient riddle.     

The bodily complexity of truth‐telling in qualitative research: Some implications of Gendlin's theory

Abstract

Gendlin's philosophy of the body is used as an approach to the “truth values” of qualitative research. In this view, our bodily participation in life provides a grounded quality to understanding, a shared reference point for an experientially‐grounded language that can “'work.” This understanding is a bodily‐informed practice and involves the body's access to “more than words can say.” As such, the body is intimate to understanding and such bodily‐informed sense‐making adds a dimension to the ways we have access to and present truth. Implications of this approach for qualitative methodology will be discussed, in particular the implications for the informant's task, the interviewer's task, the task of analysis and the task of the reader.     

Working memory in healthy aging and in Parkinson’s disease: evidence of interference effects

Focusing on relevant information while suppressing the irrelevant one are critical abilities for different cognitive processes. However, their functioning has been scarcely investigated in the working memory (WM) domain, in both healthy and pathological conditions. The present research aimed to study these abilities in aging and Parkinson’s disease (PD), testing three groups of healthy participants (young, older and elderly) and one of PD patients, employing a new experimental paradigm. Results showed that the transient storing of irrelevant information in WM causes substantial interference effects, which were remarkable in elderly individuals on both response latency and accuracy. Interestingly, PD patients responded faster and were equally accurate compared to a matched control group. Taken together, findings confirm the existence of similar mechanisms for orienting attention inwards to WM contents or outwards to perceptual stimuli, and suggest the suitability of our task to assess WM functioning in both healthy aging and PD.     

Destination memory in social interaction: better memory for older than for younger destinations in normal aging?

Destination memory, a memory component allowing the attribution of information to its appropriate receiver (e.g., to whom did I lend my pen?), is compromised in normal aging. The present paper investigated whether older adults might show better memory for older destinations than for younger destinations. This hypothesis is based on empirical research showing better memory for older faces than for younger faces in older adults. Forty-one older adults and 44 younger adults were asked to tell proverbs to older and younger destinations (i.e., coloured faces). On a later recognition test, participants had to decide whether they had previously told some proverb to an older/younger destination or not. Prior to this task, participants reported their frequency of contact with other-age groups. The results showed lower destination memory in older adults than in younger adults. Interestingly, older adults displayed better memory for older than for younger destinations. The opposite pattern was seen in younger adults. The low memory for younger destinations, as observed in older adults, was significantly correlated with limited exposure to younger individuals. These findings suggest that for older adults, the social experience can play a crucial role in the destination memory, at least as far as exposure to other-age groups is concerned.     

The critical distance of interaction in the Zöllner illusion

Two experiments attempted to de termine the distance (as visual angle) over which the Zöllner distortion of a straight line could be produced by a background field. Experiment 1 showed that the background lines did not need to intersect the test line in order to distort it but could exert this effect up to a distance of 1 deg visual angle from it. Experiment 2 indicated that when the background lines do intersect the test line portions of these formed beyond an angle of 1 deg do not contribute to the distortion. These values may indicate the size of the cortical receptive fields interacting to produce the illusion.     

Lateral inhibition and echoic memory: Some comments on Crowder’s (1978) theory

Crowder (1978) has proposed a theory of the suffix effect based on lateral inhibition among echoic representations of the list and suffix items. The theory was prompted by, and derives its principal support from, the counterintuitive finding that the effect is smaller with multiple suffixes than with a conventional single suffix. In this paper, we describe four experiments, each of which fails to replicate this finding. In addition, we note a prediction of the theory and show that it is contrary to available evidence. It is argued that the details of the suffix effect are too complex to be captured by a theory of peripheral mechanism, even one as ingenious as Crowder’s.     

Establishment sociology: The value of being value‐free

This is an excursion into the sociology of American sociology. It is an attempt to present a typology of the relationship between sociological empiricism as an ideology, and the pre‐eminence and power of empiricist sociologists. Toward this end, such concrete factors as recruitment practices, educational orientations, status strivings of the social scientists, forms of financial subsidization, and the profes‐sionalization of the field are taken into account. The article concludes by noting the limited field of investigations open to sociological empiricism, and its general impoverishment as the leading ideology of the science of sociology.     

The Renewal of Dewey – Trends in the Nineties

This article proposes that the `renewal' of Dewey might contributeto filling the gap between the pedagogical commitment tocontingency and plurality and the fact that the pedagogicaltradition, until now, has neutralized contingency and deniedits systematic meaning for education. Therefore, the maintraits of the `renewal of Dewey' are shown in thework of some Dewey scholars who, critically and creatively,reconstruct Dewey in the mirror of poststructural, communicational and constructive theory developments.Following Dewey, these researches balance the objectiveevaluation of Dewey's work by a deliberate and overtpursuit of their own intentions and (pre-)selections by the scholars.Intersubjectivity and communication are key concepts in thisrenewal of pragmatism rejecting the subject-centered philosophy of consciousness, the traditional westernepistemology and metaphysics. The turn to the philosophicalpriority of the unforeseeable also leads to anunderstanding of action as an essentialfocus. In this context Dewey's pragmatistic view of radical democracy is received as a non-foundationaltheory and the concept of consensus is criticized.The scholars clarify that the boundaries of the subjectare broadened by communicative destabilization.At the end of the article it is asked what the renewal-dimensions mean for education locatedin the public sphere.     

Is there anything special about the aging of source memory?

A battery of cognitive tests designed to measure the constructs of episodic memory, perceptual speed, fluid ability, executive functioning, and vocabulary was administered to 330 adults between the ages of 18 and 89. Each participant also performed 4 different tasks designed to assess source memory. Structural equation modeling was used to evaluate the validity of a source-memory construct and to explore the relation of the source-memory construct to age and to the other cognitive variables. The variance common to the source-memory variables was strongly related to other cognitive abilities, suggesting that source memory may not have discriminant validity, and there were only small unique age-related effects on the source-memory construct after the influence of other abilities was considered.     

The importance of working memory updating in the Prisoner’s dilemma

Successful cooperation requires that humans can flexibly adjust choices to their partner’s behaviour. This, in turn, presupposes a representation of a partner’s past decisions in working memory. The aim of the current study was to investigate the role of working memory processes in cooperation. For that purpose, we tested the effects of working memory updating (Experiment 1) and working memory maintenance demands (Experiments 2 and 3) on cooperative behaviour in the Prisoner’s dilemma game. We found that demands on updating, but not maintenance, of working memory contents impaired strategy use in the Prisoner’s dilemma. Thus, our data show that updating a partner’s past behaviour in working memory represents an important precondition for strategy use in cooperation.     

The consequences for memory of imagining in another person’s voice

Subjects listened to and imagined words and then attempted to discriminate words they had heard from words they had imagined. Discrimination was better when subjects imagined themselves saying the words (Experiments 1 and 2) than when subjects imagined the words in the speaker’s voice. Subjects also had more difficulty discriminating imagined from perceived words when they imagined in the speaker’s voice than when they imagined words in a voice other than their own or the speaker’s (Experiment 1). The results are consistent with the idea that reality monitoring is affected by the degree of similarity in sensory characteristics of memories derived from perception and from imagination (Johnson & Raye, 1981).     

The joint effect of forward and backward visual masking: Some comments on Uttal’s “Character in the hole” experiment

The joint effect of forward and backward visual masking appears to be more extended in time than that predicted from an algebraic summation of individual forward and backward masking effects. It is suggested that this apparent extension of the temporal range of masking arises from the summation of forward and backward masking effects which in themselves are insufficient to influence observed performance. Such latent masking effects are possible if it is not assumed that when stimulus identification reaches the 100% level the mask has no effect at all on the stimulus.
