Memory factors in Rey AVLT: Implications for early staging of cognitive decline

Supraspan verbal list learning is widely used to assess dementia and related cognitive disorders where declarative memory deficits are a major clinical sign. While the overall learning rate is important for diagnosis, serial position patterns may give insight into more specific memory processes in patients with cognitive impairment. This study explored these patterns in a memory clinic clientele. One hundred eighty three participants took the Rey Auditory‐Verbal Learning Test (RAVLT). The major groups were patients with Alzheimer's disease (AD), Vascular Dementia (VD), Mild Cognitive Impairment (MCI), and Subjective Cognitive Impairment (SCI) as well as healthy controls (HC). Raw scores for the five trials and five serial partitions were factor analysed. Three memory factors were found and interpreted as Primacy, Recency, and Resistance to Interference. AD and MCI patients had impaired scores in all factors. SCI patients were significantly impaired in the Resistance to Interference factor, and in the Recency factor at the first trial. The main conclusion is that serial position data from word list testing reflect specific memory capacities which vary with levels of cognitive impairment.     

Norwegian airline passengers are not more afraid of flying after the terror act of September 11. The flight anxiety,however, is significantly attributed to acts of terrorism

The aim of this paper is to study: (1) the prevalence of flight anxiety among Norwegian airline passengers; (2) situations that may be of concern during flights and situations not related to flying; (3) whether passengers feel more afraid after the terror act of September 11, 2001; and (4) whether passengers were more afraid in 2002 than in 1986.A questionnaire was distributed during domestic flights in Norway in 1986 and 2002. To asses flight anxiety, a six point scale was used, from 0 = not afraid at all, to 5 = always very afraid, and sometimes avoid flying because of that. A 10‐cm visual analogue scale (VAS) was used to measure the degree of anxiety. There were 50.8% who were not afraid at all. There were 12 women (5.2%) and one man (0.4%) with flight phobia. However, 22 (4.5%) had cancelled flights because of anxiety during the last two years. Situations that caused most concern during flights were turbulence and fear of terrorism and highjacking. After September 11, 48% were not more afraid, 38% a little more, 10% moderately, 3% rather much and 2% very much. The passengers, however, were not more afraid of flying in 2002 than in 1986. About 3% of Norwegian airline passengers have a flight phobia. Women are significantly more concerned than men. The impact of the terror act September 11, 2001 was rather moderate. The level of flight anxiety among Norwegian airline passengers was not significantly different in 2002 and 1986.     

Cognitive Complexity and Dissociative Identity Disorder

Thirteen patients with dissociative identity disorder (DID), 13 with other mental disorders, and 10 nondiagnosed comparison participants were given individual grids. Results showed that displaying alternate personalities did not portend a more multidimensional level of thinking. Instead, the nonclinical comparison group had the greater degree of complexity in comparison to both clinical groups. A notable clinical observation was that DID patients, as compared to non-DID participants, had a greater understanding and speed in completing the grid. Findings are discussed in terms of the advantages of personal construct theory for conceptualizing the construct of dissociation.     

Childhood Adverse Experience: Yes or No? Mothers' Decision-Making Process When Responding to Survey Questions

The aim of this pilot study was to assess how difficult it is for mothers to answer questions regarding adversities their children might have experienced, and to investigate their considerations in the decision-making process. A nonrepresentative community sample of 628 mothers of 6- to 8-year-old children responded to an online survey. The mothers answered questions regarding adversities, rated the acceptability of these questions, and reported on any difficulties they had in responding. Based on the mothers' reports, qualitative analyses were conducted to identify metacategories of arguments. The study highlights the need for increased awareness of the complexity involved in soliciting information about adverse experiences in research and clinical settings, and for caution in interpreting epidemiological results in this field.     

How Much for the Child?

In this paper we explore what sacrifices you are morally required to make to save a child who is about to die in front of you. It has been argued that you would have very demanding duties to save such a child (or any adult who is in similar circumstance through no fault of their own, for that matter), and some examples have been presented to make this claim seem intuitively correct. Against this, we argue that you do not in general have a moral requirement to bear more than moderate cost to save even a child who is just in front of you. Moreover, we explain why you have a much more demanding moral requirement in certain cases by appealing to the notions of undue risk and cost sharing.     

Rumfitt on the logic of set theory

According to a famous argument by Dummett, the concept of set is indefinitely extensible, and the logic appropriate for reasoning about the instances of any such concept is intuitionistic, not classical. But Dummett's argument is widely regarded as obscure. This note explains how the final chapter of Rumfitt's important new book advances our understanding of Dummett's argument, but it also points out some problems and unanswered questions. Finally, Rumfitt's reconstruction of Dummett's argument is contrasted with my own preferred alternative.     

Adolescent Suicide Attempters: What Predicts Future Suicidal Acts?

Predictors for repetition of suicide attempts were evaluated among 92 adolescent suicide attempters 9 years after an index suicide attempt (90% females). Five were dead, two by suicide. Thirty-one (42%) of 73 had repeated a suicide attempt. In multiple Cox regression analysis, four factors had an independent predictive effect: comorbid disorders, hopelessness, having ever received treatment for mental or behavior problems, and having a father exerting control without affection. Prediction on an individual level was difficult. Since almost half repeated a suicidal act, the best strategy is to evaluate all adolescent suicide attempters thoroughly and provide treatment as needed.     

EXPLAINING EMERGENCE: TOWARDS AN ONTOLOGY OF LEVELS

The vitalism/reductionism debate in the life sciences shows that the idea of emergence as something principally unexplainable will often be falsified by the development of science. Nevertheless, the concept of emergence keeps reappearing in various sciences, and cannot easily be dispensed with in an evolutionary world-view. We argue that what is needed is an ontological non reductionist theory of levels of reality which includes a concept of emergence, and which can support an evolutionary account of the origin of levels. Classical explication of emergence as “the creation of new properties” is discussed critically, and specific distinctions between various kinds of emergence is introduced for the purpose of developing an ontology of levels, framed in a materialistic and evolutionary perspective. A concept of the relation between levels as being inclusive is suggested, permitting the “local” existence of different ontologies. We identify, as a working hypothesis, four primary levels and explicate their nonhomomorphic interlevel relations. Explainability of emergence in relation to determinism and predictability is considered. Recent research in self-organizing non-linear dynamical systems represents a revival of the scientific study of emergence, and we argue that these recent developments can be seen as a step toward a final “devitalisation” of emergence.     

A critical discussion of Prior’s philosophical and tense-logical analysis of the ideas of indeterminism and human freedom

This paper is a critical discussion of A.N. Prior’s contribution to the modern understanding of indeterminism and human freedom of choice. Prior suggested that these ideas should be conceived in terms of his tense logic. It can be demonstrated that his approach provides an attractive formalization that makes it possible to discuss indeterminism and human freedom of choice in a very precise manner and in a broader metaphysical context. It is also argued that Prior’s development of this approach was closely linked to his very personal struggles with fundamental religious and metaphysical questions. In his opinion, holding the doctrine of divine foreknowledge together with the doctrine of human freewill gives rise to difficult logical and philosophical problems. It appears that Prior, rather early on, decided to support what was later known as the Peircean solution, although he also analysed what he considered to be the most important alternative solution—the Ockhamist solution. This paper offers a discussion of some of Prior’s published books and papers as well as some of the papers in his Nachlass.
