Bilingualism Is Associated with a Delayed Onset of Dementia but Not with a Lower Risk of Developing it: a Systematic Review with Meta-Analyses

Neuropsychology Review - Some studies have linked bilingualism with a later onset of dementia, Alzheimer’s disease (AD), and mild cognitive impairment (MCI). Not all studies have observed...     

On the Genus and Species of Recognition

This article makes several conceptual proposals for a closer analysis of recognition more or less in line with Axel Honneth's account of recognition: (1) a proposal as to the genus of recognitional attitude and recognition, (2) a sketch of an analytical scheme intended to be heuristically useful for analysing the different species of recognitional attitude and recognition, (3) some proposals as to the precise contents of self-conceptions involved in each species and subspecies of recognition, and (4) suggestions as to the relation of the species of recognitional attitude to social settings and concrete personal relationships as well as to the totalities of attitudes instantiated in these settings and relationships. A guiding idea is that the somewhat mechanistic Meadian vocabulary of 'urges' and 'internalizations' of Honneth's original formulations should be replaced with formulations where recognition is consistently conceptualized as consisting of attitudes with propositional or judgmental content.     

Long-term associations of stress and chronic diseases in ageing and retired employees

Long-term associations of prolonged stress symptoms and work-related stressors with chronic diseases were assessed in a sample of ageing and retired food industry workers (N = 100, mean age 62 years) using independent samples t-test, chi-squared test and binary logistic regression analyses. Data was gathered at health checkups and using self-report questionnaires in 1989 and 2000. Prolonged stress symptoms were associated with overall morbidity. Higher scores of stress symptoms predicted musculoskeletal disorders, diseases of the nervous system, eye and ear, endocrine and metabolic diseases, and mental disorders. Of work-related stressors, only job dissatisfaction had a long-term association with endocrine and metabolic diseases. Importantly, prolonged stress symptoms could not be explained by job strain and demands. Identification of prolonged stress symptoms along with traditional and potential risk factors, and combining this knowledge with stress reduction and management is essential for disease prevention and in postponing subsequent onset of disease.     

The effects of different intensity levels of background noise on dichotic listening to consonant-vowel syllables

It has previously been shown that the right ear advantage in dichotic listening to consonant-vowel syllables is affected if a background noise is presented at the same time as the dichotic stimuli. What is not known is, however, if there is also an effect of varying the intensity level of the background noise. We therefore presented conversation or traffic noise background noise simultaneously with the dichotic syllable stimuli to healthy adult subjects. The intensity of the background noises varied between 50-65 dB in steps of 5 dB. The results showed that the right ear correct reports decreased, while left ear correct reports increased as a consequence of increasing background noise intensity. The effects were also stronger for the right ear, and for the traffic background noise condition, particularly at the two highest intensity levels. The results are discussed in terms of alertness and attentional mechanisms.     

Does traffic congestion increase driver aggression?

In his recent article about aggressive driving, David Shinar proposed that the classical frustration-aggression hypothesis (Dollard, J., Doob, L., Miller, N., Mowrer, O. & Sears, R. (1939). Frustration and aggression. New Haven, CN: Yale University Press) provides a useful tool for understanding driver aggression (Shinar, D. (1998). Aggressive driving: the contribution of the drivers and situation. Transportation Research Part F, 1, 137–160). According to Shinar's (1998) application of the frustration–aggression hypothesis, driver aggression is caused by frustration because of traffic congestion and delays. In the present study, the relationships between exposure to congestion (rush-hour driving) and aggressive violations (DBQ) were investigated in Great Britain, Finland and the Netherlands. Partial correlations showed that the frequency of rush-hour driving did not correlate statistically significantly with driver aggression. Correlations between driving during rush-hour and aggression did not differ in magnitude from those between driving on country roads and aggressive violations. In addition, correlations between exposure to congestion and aggressive violations in countries with large number of vehicles per road kilometre (UK, Netherlands) were not higher than those in a sparsely populated country (Finland). These results from three countries suggest that congestion does not increase driver aggression as directly as suggested by Shinar (1998).     

Psychosynthesis of the brain and mind: Comments on a new intellectual framework in psychiatry and psychotherapy

Abstract

Eric R. Kandel, the Nobel Prize winner of 2000 in physiology and medicine, emphasises five scientific principles of which psychiatrists must be aware and which are presented and critically analysed in this article. Kandel states that professional requirements for future psychiatrists will impose a greater knowledge of the structure and functioning of the brain, and that the rationale for the unique domain that psychiatry occupies within academic medicine is the analysis and understanding of the interaction between the social and biological determinants of behaviour. The work of a psychotherapist is based both on scientific knowledge and, to a large extent, on an empathic understanding of the patient's history as well as his or her verbal and non-verbal expressions – as a consequence, the orientation of hermeneutic philosophy and semiotics should also be included in the intellectual framework. The aim of this paper is to update the channels of communication between modern neurobiology, psychoanalysis, semiotics and philosophy to the best advantage for their multidisciplinary, holistic cooperation.     

Visuospatial representations used by chess experts: A preliminary study

Blindfold chess is played without the players seeing either the pieces or the board. It is a skill‐related activity, and only very skilled players can construct the mental images required. This is why blindfold chess provides a good task with which to investigate the spatial memory and skilled mental images of expert players. In a PET investigation, we compared memory performance and problem solving in very experienced chess players with their performance in an attention task, in which the subjects classified the names of chess pieces. The memory task predominantly activated the temporal areas, whereas problem solving activated several frontal areas. The relevance of these findings to concepts such as general imagery, skilled imagery, apperception, and long‐term working memory are discussed.
