Plasticity of memory for new learning in very old age: a story of major loss?

Longitudinal survivors of the Berlin Aging Study (N = 96, mean age = 84 years, range 75-101 years) were instructed and trained in a mnemonic skill to examine plasticity of episodic memory performance in very old age. Performance gains after mnemonic instruction were modest, and most individuals were unable to further enhance their performance during 4 sessions of mnemonic practice. Whereas the proportion of variance explained by measures from the broad fluid-ability domain (e.g., perceptual speed) increased with training, the proportion of variance explained by crystallized-ability domain (e.g., word knowledge) and sociobiographical variables decreased. Furthermore, prior 6-year longitudinal changes (loss) in perceptual speed predicted individual differences in plasticity. Results suggest that aging-induced biological factors are a prominent source of individual differences in cognitive plasticity in very old age.     

“A new and modern golden age of Jewish culture”: shaping the cultural politics of transnational Jewish antifascism

The Holocaust and a worldwide Jewish enthusiasm and support for the Red Army’s defeat of the German Army on the Eastern Front led to a greater sense of international Jewish consciousness and solidarity often tied to an antifascist politics. Utilizing a transnational lens, I explore how Jewish antifascists of the immediate post-war period proffered a novel cultural politics as a means of addressing ongoing international issues of post-Holocaust Jewish survival in a dangerous and politically uncertain modernity. I examine three Jewish left magazines of the late 1940s that were involved in a loose international antifascist progressive Jewish network and ideological framework. These magazines Jewish Life (USA), New Life (UK) and Unity (Australia) represented similar antifascist politics and cultural outlooks in the USA, Britain and Australia, respectively. They have received little sustained scholarly attention previously. I analyse their vision of diverse multilingual Jewish cultures which were to be promoted and developed in any country where Jews lived and in whatever language they spoke. Their cultural vision represented antifascist values against bourgeois or nationalist Jewish culture and broadly reflected a pro-Soviet, progressive and Jewish internationalist, Popular Front politics and worldview.     

How new is the new philosophy of psychiatry?

In their recent paper, Natalie Banner and Tim Thornton evaluate seven volumes of the Oxford University Press series “International Perspectives in Philosophy and Psychiatry,” an international book series begun in 2003 focusing on the emerging interdisciplinary field at the interface of philosophy and psychiatry. According to Natalie Banner and Tim Thornton, the series represents a clear indication that the interdisciplinary field of philosophy of psychiatry has been flourishing lately. Philosophers and psychiatrists face a “new philosophy of psychiatry”. However, the optimism which the “new” philosophy of psychiatry celebrates is precisely the exiling of philosophy from the foundations of psychiatry. The 150 year old belief that psychopathology cannot do without philosophical reflection has virtually disappeared from common psychiatric education and daily clinical practice. Though the discipline of psychiatry is particularly suited to contributions from philosophy, the impact of philosophy on psychiatry nowadays remains limited. With some exceptions, philosophical papers are embedded in a philosophical context inscrutable to ordinary psychiatrists. Much current philosophical work is perceived by psychiatrists as negativistic. I would encourage the field of psychiatry to incorporate once again basic philosophical attitudes which render possible true dialogue with philosophy and enrich both disciplines. The views developed here should not discredit the value and importance of Natalie Banner and Tim Thornton’s paper and the excellent series “International Perspectives in Philosophy and Psychiatry.” As Jaspers said “Everybody inclined to disregard philosophy will be overwhelmed by philosophy in an unperceived way”.     

Cognitive and communicative function: The effects of chronological age and “handicap age”

Abstract

Three classes of cognitive tests (short-term memory, long-term memory access/recall, and verbal ability) and one class of communicative tests (visual speech-reading) were administered to 49 hearing-impaired and 69 normal hearing subjects, varying in age between 23 and 75 years. It was found that when dB-loss and “handicap age” were partialled out, the negative effects of cognitive ageing remained: Speed in accessing alphanumeric symbols from long-term memory and as rehearsal speed correlated substantially with chronological age. Discriminant analyses revealed a communality between the discrimination of old from young subjects, and skilled from less skilled speech-readers: Visual decoding skill and rehearsal speed constituted the common discriminators. Departing from this result, an age-dependent componential model of visual speech-reading is delineated. with particular reference to the assumption that a temporally early lexical access system is crucial to the decoding of lip movements.     

What causes the effect of age of acquisition in lexical processing?

Three hypotheses for effects of age of acquisition (AoA) in lexical processing are compared: the cumulative frequency hypothesis (frequency and AoA both influence the number of encounters with a word, which influences processing speed), the semantic hypothesis (early-acquired words are processed faster because they are more central in the semantic network), and the neural network model (early-acquired words are faster because they are acquired when a network has maximum plasticity). In a regression study of lexical decision (LD) and semantic categorization (SC) in Italian and Dutch, contrary to the cumulative frequency hypothesis, AoA coefficients were larger than frequency coefficients, and, contrary to the semantic hypothesis, the effect of AoA was not larger in SC than in LD. The neural network model was supported.

Developmental changes in retention: Independent of age?

It is commonly believed that age differences in memory are due primarily to input processes and secondarily, if at all, to retention processes. The present study examined this belief with a test-retest paradigm, varying rehearsal conditions orthogonal to age (first- and second-graders vs. college students). Large age effects were found for both original learning and retention, and these effects were independent of rehearsal conditions. An estimate of the relative magnitude of each suggested that age effects on retention were about half as large as age effects on original learning (e.g., input).

Higher realities and the inner self: One quest? Transcendence and the significance of the body in the new age circuit

Can New Age be religious? In this article it is argued that New Age should not be treated as just one meaning system. It is possible to discern several different meaning systems in the New Age networks, even though they share a common language. Before examining whether these meaning systems are religious or, in other words, whether they contain transcendent elements, the concept of transcendence is ‘de‐christianised’. For it is precisely the Christian interpretation, namely the idea that the transcendent reality has to be ‘outside’, that makes the concept useless for the study of New Age meaning systems. The analysis then shows that sometimes there is a higher reality, and sometimes not. Even in one and the same meaning system this difference can occur, since central notions are interpreted in different ways.     

Soames’s new conception of propositions

In this paper, I argue that, when it comes to explaining what can be described as “representational” properties of propositions, Soames’s new conception of propositions—on which the proposition that Seattle is sunny is the act of predicating the property being sunny of Seattle and to entertain that proposition is to perform that act—does not have an advantage over traditional ones.     

Antecedents of fathers’ perception of child behavior at child age 12 months

This study investigates whether fathers’ adverse childhood experiences (ACE) and attachment style reported during pregnancy predict fathers’ perception of child behavior assessed 12 months postpartum, expressed by the Parenting Stress Index (PSI), Child Domain. Prospective fathers (N = 835) were recruited to “The Little in Norway (LiN) study” (Moe & Smith) at nine well-baby clinics in Norway, with data collection composed of five time points during pregnancy and two time points postpartum (6 and 12 months). The main analyses included linear regression, path-analysis modeling, and intraclass correlation based on mixed effects modeling. First, linear regression analyses showed that neither fathers’ ACE nor attachment style significantly predicted perceived child behavior postpartum directly. Furthermore, path analyses showed that ACE and less secure attachment style (especially avoidant attachment) measured early in pregnancy strongly predicted negatively perceived child behavior, mediated by fathers’ mental health symptoms during pregnancy and partner disharmony postpartum. Second, intraclass correlation analyses showed that fathers’ perceived child behavior showed substantial stability between 6 and 12 months postpartum. Family interventions beginning in pregnancy may be most beneficial given that fathers’ early experiences and perceptions of attachment in pregnancy were associated with later partner disharmony and stress.

The ‘coming of age’ for Southern African psychobiography

This study investigated the effects of perceived values (personal, artistic, and sociocultural) of tourists’ attitude and behavioural intention to visit Africa. Participants were tourists (176 men and 124 women) who visited the Museum of African Art based on Jeju Island in the Republic of Korea. Results, following hierarchical analysis, suggest personal value and sociocultural value rather than artistic value to predict tourists’ attitude and behavioural intention to visit Africa. The findings of this study imply that personal and sociocultural predispositions lead to the tourists’ likely adoption of a tourist destination beyond familiarities with artistic works associated with the destination. Tourism promotion campaigns aimed at promoting African as a destination should customise messages to address the personal and sociocultural predispositions of would-be international tourists.     

The square of opposition — A new approach

Summary The theory of the square of opposition has been worked out many centuries ago as a part of Aristotelian logic of terms.In spite of its inexactness (for instance it is not possible to decide whether the termsquare of opposition is a logical or a metalogical term) this theory is included without any changes in the usual elementary course of logic.The author defines the square of opposition in the language of the logic of propositions (see Def. 1.000) and derives from this definition the usual laws of the square of opposition and several new theorems.     

Do children need to learn to collaborate?: The effect of age and age differences on collaborative recall

We used a collaborative recall task to explore the nature and consequences of children's interaction with another child at the same or different age. Ninety-six children memorised word lists for recall. In a first condition children recalled collaboratively: in a pair with another child. In a second condition children recalled words independently (this made possible the creation of “nominal” pairs for comparison). Pairs were either composed of two 7-year-olds, two 9-year-olds, or a 7- and a 9-year-old. Older pairs, like adults, showed a net negative effect of collaborative recall. However, younger children showed no effects of collaboration. Analyses of the different contributions offered by each child in a pair, and of measures of social dominance suggest that older children dominate social aspects of interaction and recall when paired with a younger child. We argue that younger children may lack full awareness of the role of interaction as a forum for the co-construction of knowledge.     

Does manual asymmetry of right-handers change between six and nine years of age?

The development of manual asymmetry was studied in rhythmic tapping tasks and in repetitive timed tapping tasks on a sample of normal 6- and 9-year-olds. All subjects were right-handed. On all tappings tasks performance improved between 6 and 9 years of age. The right preferred hand induced better performance than the left non-preferred hand on all tasks except successive tapping on one key with the four fingers. On rhythmic tapping tasks the asymmetry in stability of rhythm favoring the right hand was more pronounced in younger than in older children. However, asymmetry in the discrepancy between the expected and the actual number of beats per trial on rhythmic tapping did not change with age. On the three repetitive timed tasks there was no change of asymmetry with age. These results are analyzed in the light of findings reported by other authors.     

Is gerontology a branch of astrology? The role of advanced age in scientific explanation

Although gerontologists have been troubled by meta-scientific problems such as the proper definition of their discipline, the nature of time and age, and the lack of a nonarbitrary distinction between the old and the not old [e.g., Baltes & Goulet (1970) In Life-span developmental psychology (pp. 4–23). New York: Academic Press; Birren (1959) In Handbook of aging and theindividual (pp. 3–42). Chicago, IL: University of Chicago Press; McKee (1982) Philosophical foundations of gerontology. New York: Human Sciences Press; Reese & Overton (1970) In Life-span developmental psychology (pp. 116–149). New York: Academic Press; Wohlwill (1970) Psychological Review, 77, 49–647], philosophers of science have paid little attention to the meta-scientific problems of gerontology. In this paper some philosophical problems in gerontology are examined through an analysis of the nature of scientific explanation. An argument is presented that claims that gerontology avoids many of the meta-scientific problems associated with time and advanced chronological age because these terms will tend to be obviated or “screened off” in scientific explanations in gerontology.     

“Upright” orientations of forms change with subject age and with features of form

This research investigated the role of certain intrinsic features of two-dimensional nonrepresentational forms in their judged “upright” orientation. The forms were individually projected by an apparatus that allowed rotation through the 360-deg range. The subjects (from kindergarten, 2nd, 4th, 6th, college grades) were asked to place each form in “upright” orientation. For some forms, these chosen orientations were the same for all age groups, apparently reflecting the universal and equal effect of certain intrinsic features. For other forms, chosen orientation changed systematically across age, in a manner possibly reflecting the influence of reading-scansion habits that changed with age. The intrinsic features related to upright judgments were symmetry, polar axes, texture lines, taper, and flat bottoms. Results partly disconfirm the hypothesis that forms are judged “upright” with their “focal portions” at the top.     

Reading in Spanish and Italian: Effects of age of acquisition in transparent orthographies?

Despite the similar transparency of their orthographies, reading in Italian has been found to be affected by frequency but not age of acquisition (AoA) [Barca, L., Burani, C., & Arduino, L. S. (2002). Word naming times and psycholinguistic norms for Italian nouns. Behaviour Research Methods, Instruments and Computers, 34, 424–434] while reading in Spanish is affected by AoA but not frequency [Cuetos, F., & Barbón, A. (2006). Word naming in Spanish. European Journal of Cognitive Psychology, 18, 415–436]. We examined this cross-linguistic difference, firstly, through a reanalysis of the Italian and Spanish reading latencies. After eliminating several between-experiment differences, we replicated the AoA effect in Spanish but not in Italian and the frequency effect in Italian but not in Spanish. The cross-linguistic comparison could not equate stimulus imageability; therefore, secondly, we compared the Italian reading latencies with new Spanish reading latencies for imageability-matched words. We found frequency effects but neither an AoA effect nor a language by AoA interaction. We argue that the previously reported cross-linguistic difference in the AoA effect resulted from a between-study difference in stimulus imageability. More imageable words induced more semantic involvement in reading, yielding an AoA effect in Spanish.
