Does Philosophy of Action Rest on a Mistake?

Philosophers of action tend to take for granted the concept of basic actions – actions that are done at will, or directly – as opposed to others that are performed in other ways. This concept does foundational work in action theory; many theorists, especially causalists, take part of their task to be showing that normal, complex actions necessarily stem from basic ones somehow. The case for the concept of basic actions is driven by a family of observations and a cluster of closely related anti-infinite regress arguments. I review this case in the work of Arthur Danto, Donald Davidson, and Jennifer Hornsby – three of the most important developers of the concept – and find it lacking. I conclude by sketching the possibility of non-foundationalist action theory.     

Does the Traditional Treatment of Enthymemes Rest on a Mistake?

In many actual arguments, the conclusion seems intuitively to follow from the premisses, even though we cannot show that it follows logically. The traditional approach to evaluating such arguments is to suppose that they have an unstated premiss whose explicit addition will produce an argument where the conclusion does follow logically. But there are good reasons for doubting that people so frequently leave the premisses of their arguments unstated. The inclination to suppose that they do stems from the belief that the only way in which an argument's conclusion can follow definitely from its premisses is to follow logically. I argue that this belief is mistaken. I propose a revision of the current generic conception of logical consequence, and its variant specifications, to avoid the paradoxes of strict implication. The revised conception can then be naturally extended to include also what we might call 'enthymematic consequence'. This concept is a kind of consequence, whose properties merit investigation.     

Does timeframe adjustment of the Life Orientation Test-Revised assess optimism as a state?

ABSTRACT

Optimism is prospectively associated with superior health outcomes in cardiac patients, making it an attractive target for well-being interventions in this population. However, optimism measured by the Life Orientation Test-Revised (LOT-R) has largely been considered a static, dispositional construct. Among 125 patients with a recent acute coronary syndrome who received a positive psychology intervention, we assessed the properties of a modified LOT-R that changed the timeframe of items from general dispositional statements to queries about ‘right now.’ We aimed to learn whether this modified LOT-R was more dynamic than the original LOT-R via administration of both instruments at three timepoints over the 16-week study period. Contrary to our hypothesis, this modified LOT-R showed no greater change in mean score or intra-individual variance than the original LOT-R over 16 weeks. This suggests that simply changing the timeframe of the LOT-R may not facilitate assessment of more state-like optimism in medical patients.     

End of Life Pediatric Research: What About the Ethics?

Clinical trials are required in order to develop new treatments and improve both patient life expectancy and quality of life. In this respect the last 10 years proved their efficiency. However clinical research shows one of the most difficult dilemmas from an ethical point of view. Patients included in clinical trials are submitted to known and unknown risks and hazards, but rarely benefit from the results. This is even more evident when clinical trials use children who are terminally ill. The core consideration becomes how far should we go with research when considering the child best interest.     

Does Death Render Life Absurd?

In this paper, I assess the claim that death renders life absurd. First, I characterize absurdity as something we perceive in situations involving extreme disharmonies which strike us as unexpected or unacceptable. Next, I outline several potential disharmonies which death might introduce into our existence (such as the disharmony between our dignity and capacities, and the undignified annihilation which death promises), but suggest that these examples need not be seen as necessarily absurd; there are perspectives available to us from which these facts can appear to be acceptable aspects of life. Finally, I consider a more problematic case of absurdity—that human beings allegedly fail to grasp the truth of their mortality—but suggest that the underlying disharmony here can be eliminated provided we develop an authentic attitude toward death (and that this is possible, despite some objections). In short, I argue that none of the most obvious potential absurdities which might arise from our mortality are strong enough to entail the claim that death inevitably renders life absurd, at least on one plausible and interesting interpretation of that claim.     

The Effect of Participating in Suicide Research: Does Participating in a Research Protocol on Suicide and Psychiatric Symptoms Increase Suicide Ideation and Attempts?

The effect of engaging in an intensive research protocol that inquired extensively about psychiatric and suicide symptoms and exposed participants to a number of images, including suicide-related content was explored. Individuals experiencing a major depressive episode were called at 1 and 3 months after the initial protocol. Participants were asked about changes in suicide ideation and the occurrence of self-harm or suicide attempts following participation. Participants reported experiencing reductions in suicide ideation at the first follow-up and no changes at the second follow-up. No participant reported having engaged in self-harm or having attempted suicide at either follow-up. Results suggest that basic science/nontreatment research can be conducted safely with suicidal participants and in a manner that does not increase suicide symptoms or suicide risk.     

Does Life Satisfaction Determine Subjective Health?

The majority of previous studies on life satisfaction and health status were conducted in the advanced developed countries, while less attention has been focused on transitional countries, especially those in Central Asia, the Caucasus, and the Balkans. This study is among a very few studies that focused on the regions which faced on the prolonged economic and political crisis during the transition. Drawing on comparable data from 28 transitional countries in Eastern and Central Europe, the Caucasus, the Central Asia, and Turkey, we quantify the effect of self-reported life satisfaction on the self-reported health status of the population. To rule out reverse causality and to reduce estimation biases, we employed simultaneous equation models with instrumental variables. Two models used standard simultaneous equation regression (2SLS) and bivariate ordered probit regression (bioprobit) for categorical ordered variables. Our main finding is that, regardless of the model used, higher levels of life satisfaction determine higher health status. The mechanisms regarding the effects of life satisfaction on health are discussed. Future researchers are encouraged to include life satisfaction in their analyses of health status. From a methodological standpoint, we demonstrate that a strong endogeneity exists between life satisfaction and health status, regardless of the models used. Ignoring endogeneity and estimating a single stage regression model with life satisfaction and health status will likely lead to biased results.     

Does a Religious Transformation Buffer the Effects of Lifetime Trauma on Happiness?

A number of studies have examined religious transformations. But most of this work has been concerned with identifying different types of transformations and steps in the process of transformation. The current study was designed to examine the ways in which religious transformations may be associated with happiness. We take a novel approach toward the evaluation of this relationship. We argue that a religious transformation may be an important resource for coping with lifetime trauma. Two major findings emerge from our nationwide survey (N = 2,851). First, the data indicate that the magnitude of the relationship between lifetime trauma and happiness is reduced significantly for people who have had a religious transformation but not for those who have not had this type of religious experience. Second, the results reveal that the potential stress-related benefits of a religious transformation are more evident among younger adults than among middle-aged or older adults.     

Does empirical moral psychology rest on a mistake?

Many philosophers assume that philosophical theories about the psychological nature of moral judgment can be confirmed or disconfirmed by the kind of evidence gathered by natural and social scientists (especially experimental psychologists and neuroscientists). I argue that this assumption is mistaken. For the most part, empirical evidence can do no work in these philosophical debates, as the metaphorical heavy-lifting is done by the pre-experimental assumptions that make it possible to apply empirical data to these philosophical debates. For the purpose of this paper, I emphasize two putatively empirically-supported theories about the psychological nature of moral judgment. The first is the Sentimental Rules Account, which is defended by Shaun Nichols. The second is defended by Jesse Prinz, and is a form of sentimentalist moral relativism. I show that both of the arguments in favour of these theories rely on assumptions which would be rejected by their philosophical opponents. Further, these assumptions carry substantive moral commitments and thus cannot be confirmed by further empirical investigation. Because of this shared methodological assumption, I argue that a certain form of empirical moral psychology rests on a mistake.     

Does a panel discussion on analytic technique have any effect on an audience of analysts?

This is a report of a followup study to determine whether attending a panel discussion group on post-termination patient-analyst contact influenced the analytic audience's attitude on that subject. A questionnaire about post-termination contact was given to 21 analysts who did not attend the discussion group and to 45 analysts before they attended. The same questionnaire was given again to both groups six months later. Responses by the 21 analysts who had not been present remained essentially unchanged. Responses of the 45 analysts, after attending the discussion group, when compared to responses of an earlier group of 300 analysts, showed an increase in the proportion of analysts who said, in reference to psychoanalytic psychotherapy patients, either that they hoped to hear from the patient or that they would like the patient to return to see them at some specified period after treatment termination. Attendance at the discussion seems responsible for a significant effect on the analytic audience's attitude on post-termination patient-analyst contact.     

Is Age a Good Predictor of Research Productivity?

The research productivity of psychologists holding appointment in Australian universities was established at two times of measurement across groups defined with respect to chronological age and date of birth. The design allowed cross-sectional gradients to be contrasted over times of measurement, and longitudinal gradients to be compared across cohorts. Psychologists aged 26–35 years in 1970 showed no decline in publication rate between 1968–1970 and 1978–1980, while psychologists aged more than 35 years in 1970 showed a drop in research output over the 10-year period. However, a person's publication rate in 1978–1980 was better predicted by their past productivity (publication rate in 1968–1970) than by their age. These results are discussed in the context of factors that affect research productivity, as well as changes that will occur in the age distribution of Australian academics over the next 20 years.     

Does an estimate of environmental size precede size scaling on a form-comparison task?

In a number of studies reaction time has been found to increase with increases in size ratio on a same -different form-comparison task. Bennett and Warren (2002, Perception & Psychophysics 64 462-477) teased apart environmental and retinal size ratios by showing the forms along a (simulated) texture hallway, viewed monocularly, on a simultaneous form-comparison task; roughly equal effects of environmental and retinal size ratios were found. The current study enhanced scene-size information by showing the forms in simulated stereo and by adding texture to the forms themselves; special care was also taken to perceptually isolate the stimuli. In two experiments, with different kinds of forms, strong effects of environmental size ratio were found; no effect of retinal size ratio (same trials) was observed in either experiment. The results support the hypothesis that the (same-trial) form-size codings reflect 'all told' estimates of environmental size, and place constraints on modeling the functional architecture of the visual system.     

The effects of redundant communications on the behavior of listeners: Does a picture need a thousand words?

Using a referential communication paradigm, two types of, informative messages, contrastive and redundant, were compared developmentally in terms of their relative effects on the accuracy of listeners' responses as a function of task variables. Contrastive messages contained the minimal information necessary to distinguish a referent from a nonreferent. Redundant messages contained additional information. We predicted that redundant messages would be more effective than contrastive ones when the stimulus array was too complex for a listener to notice all aspects of it in the allotted time. Also manipulated were the order of presentation of the message and array and the delay between the two in order to determine how these factors would contribute to task complexity. Subjects were first-and third-graders and college students. The stimuli were drawings of cartoonlike figures. The results confirmed our predictions for the older subjects but not for the younger ones. The discussion of the data centered on why the picture-message sequence, was a more difficult sequence than the message-picture one for all age groups.     

Does a Tired Mind Help Avoid a Decision Bias? The Effect of Ego Depletion on Escalation of Commitment

In this research, we investigated the effect of ego depletion on escalation of commitment. Specifically, we conducted two laboratory experiments and obtained evidence that ego depletion decreases escalation of commitment. In Study 1, we found that individuals were less susceptible to escalation of commitment after completing an ego depletion task. In Study 2, we confirmed the effect observed in Study 1 using a different manipulation of ego depletion and a different subject pool. Contrary to the fundamental assumption of bounded rationality that people have a tendency to make decision errors when mental resources are scarce, the findings of this research show that a tired mind can help reduce escalation bias.
