Mobility: Disability and Life in the Spirit

Abstract : The author employs the narrative of his own personal experience of disability as an entry to several large issues: the place of body; the challenge of mobility; the processes of medical treatment, therapy, and fitness training; the network of dependence upon family, friends, and society; and the challenge to actively avail oneself of the resources of this network. The power of the human spirit is affirmed as the prerequisite for moving the body and attaining the possibilities of one's life. This power is the work of God's Spirit. A concept of body‐spiriting is suggested. The argument is framed in two parts: (1) in the world in my own skin, and (2) living in the presence of God.     

On the meaning and the epistemological relevance of the notion of a scientific phenomenon

In this paper I offer an appraisal of James Bogen and James Woodward’s distinction between data and phenomena which pursues two objectives. First, I aim to clarify the notion of a scientific phenomenon. Such a clarification is required because despite its intuitive plausibility it is not exactly clear how Bogen and Woodward’s distinction has to be understood. I reject one common interpretation of the distinction, endorsed for example by James McAllister and Bruce Glymour, which identifies phenomena with patterns in data sets. Furthermore, I point out that other interpretations of Bogen and Woodward’s distinction do not specify the relationship between phenomena and theories in a satisfying manner. In order to avoid this problem I propose a contextual understanding of scientific phenomena according to which phenomena are states of affairs which play specific roles in scientific practice and to which we adopt a special epistemic attitude. Second, I evaluate the epistemological significance of Bogen and Woodward’s distinction with respect to the debate between scientific realists and constructive empiricists. Contrary to what Bogen and Woodward claim, I argue that the distinction does not provide a convincing argument against constructive empiricism.     

Defection in the dark? A randomized‐response investigation of cooperativeness in social dilemma games

As previous research has demonstrated numerous times, humans show a robust tendency for cooperation. However, part—or indeed all—of this cooperativeness may be due to socially desirable responding. To address this problem, we propose and apply a new approach for the unbiased measurement of cooperativeness in social dilemma games. Specifically, we employ an extension of the randomized‐response technique (RRT). The RRT protects the privacy of respondents by adding random noise to their responses. It thus encourages more honest responding and thereby provides less biased estimates of sensitive attributes. In a large‐scale study with 2043 respondents we maximized anonymity in a one‐shot prisoner's dilemma game through use of the RRT. Comparing the prevalence rates for cooperation obtained via the RRT with those from direct self‐report showed that traditional direct questioning formats overestimate cooperation rates, with a relative bias of 18%. This finding suggests that to a considerable extent, self‐reported cooperation is due to socially desirable responding, rather than actual cooperativeness. However, our results also demonstrate that cooperation remains substantial even under conditions of maximized anonymity. Copyright © 2011 John Wiley & Sons, Ltd.     

RALPH BURHOE: RECONSIDERING THE MAN AND HIS VISION OF YOKING RELIGION AND SCIENCE

Ralph Wendell Burhoe was a leading figure in relating religion and science in the second half of the twentieth century. His autodidactic style and character as a public intellectual resulted in a vision that is comprehensive in its concern for the salvation of society. He does not fit easily into academic frameworks, even though he has been influential upon scholars who work in academia. This article discusses some conundrums posed by his work. There are also brief presentations of the concerns that motivated Burhoe, his style of work, and the content of his vision.     

Sensory memory of illusory depth in structure-from-motion

When multistable displays (stimuli consistent with two or more equally plausible perceptual interpretations) are presented intermittently, their perceptions are stabilized by sensory memory. Independent memory traces are generated not only for different types of multistable displays (Maier, Wilke, Logothetis, & Leopold, Current Biology 13:1076–1085, 2003), but also for different ambiguous features of binocular rivalry (Pearson & Clifford, Journal of Vision 4:196–202, 2004). In the present study, we examined whether a similar independence of sensory memories is observed in structure-from-motion (SFM), a multistable display with two ambiguous properties. In SFM, a 2-D planar motion creates a vivid impression of a rotating 3-D volume. Both the illusory rotation and illusory depth (i.e., how close parts of an object appear to the observer) of an SFM object are ambiguous. We dissociated the sensory memories of these two ambiguous properties by using an intermittent presentation in combination with a forced-ambiguous-switch paradigm (Pastukhov, Vonau, & Braun, PLoS ONE 7:e37734, 2012). We demonstrated that the illusory depth of SFM generates a sensory memory trace that is independent from that of illusory rotation. Despite this independence, the specificities levels of the sensory memories were identical for illusory depth and illusory rotation. The history effect was weakened by a change in the volumetric property of a shape (whether it was a hollow band or a filled drum volume), but not by changes in color or size. We discuss how these new results constrain models of sensory memory and SFM processing.     

Adoption and maintenance of physical activity: Planning interventions in young, middle-aged, and older adults

Young, middle-aged, and older adults in orthopaedic outpatient rehabilitation (N?=?373) were randomly assigned to either an interviewer-assisted or a standard-care self-administered planning intervention. Physical activity planning consisted of specifying action plans to facilitate action initiation, and coping plans to overcome barriers. The interviewer-assisted condition led to more complete action plans and a longer duration of physical activities up to six months after discharge. Regarding coping planning, older and middle-aged adults benefited more from interviewer-assisted planning while younger adults benefited more from self-administered planning. Planning as such was found to be an effective tool for enactment irrespective of chronological age. The delayed effect of coping planning on enactment suggests that coping planning is important for long-term maintenance.     

Enhanced old–new recognition and source memory for faces of cooperators and defectors in a social-dilemma game

A popular assumption in evolutionary psychology is that the human mind comprises specialized cognitive modules for social exchange, including a module that serves to enhance memory for faces of cheaters. In the present study, participants played a trust game with computerized opponents, who either defected or cooperated. In a control condition, no interaction took place. In a surprise memory test, old–new recognition for faces and source memory for the associated cooperative or non-cooperative behavior were assessed. A multinomial model was used to measure old–new discrimination, source memory, and guessing biases separately. Inconsistent with the assumption of a memory mechanism that focuses exclusively on cheating, the present study showed enhanced old–new discrimination and source memory for both cooperators and defectors. Rarity of the behavior strategies within the experiment modulated source memory, but only when the differences in base rates were extreme. The findings can be attributed to a mechanism that focuses on exchange-relevant information and flexibly adapts to take into account the relative significance of this information in the encoding context, which may be more beneficial than focusing exclusively on cheaters.     

From Religious to Consumption‐Related Routine Activities? Analyzing Ireland's Economic Boom and the Decline in Church Attendance

Using Ireland, which experienced an economic boom in the mid 1990s, as a case study, the negative association between economic growth and religious practice is examined by testing two competing hypotheses. Secularization theory argues that the cultural changes that accompany economic growth lead to a decline in religious values. As religious values diminish, so does attendance at religious services. An alternative explanation is that economic growth increases individual purchasing power and therefore consumption‐related behavior. Consumption supplants religion by providing alternative intermediaries (symbols, infrastructures, and practices) for social behavior, but only marginally affects religious values. Using data from the 1988 to 2005 International Social Survey Programme (ISSP), analyses show that the economic boom in Ireland was clearly associated with a decline in religious attendance, while religious values remained stable. Thus, in Ireland the consequences of economic growth deviate from the predictions of secularization theory and therefore support the consumption argument.     

The effects of action,normality, and decision carefulness on anticipated regret: Evidence for a broad mediating role of decision justifiability

Two distinct theoretical views explain the effects of action/inaction and social normality on anticipated regret. Norm theory (Kahneman & Miller, 1986) emphasises the role of decision mutability, the ease with which one can imagine having made a different choice. Decision justification theory (Connolly & Zeelenberg, 2002) highlights the role of decision justifiability, the perception that the choice was made on a defensible basis, supported by convincing arguments or using a thoughtful, comprehensive decision process. The present paper tests several contrasting predictions from the two theoretical approaches in a series of four studies. Study 1 replicated earlier findings showing greater anticipated regret when the chosen option was abnormal than when it was normal, and perceived justifiability mediated the effect. Study 2 showed that anticipated regret was higher for careless than for careful decisions. Study 3 replicated this finding for a sample holding a different social norm towards the focal decision. Finally, Study 4 found that, when decision carefulness, normality and action/inaction were all specified, only the former showed a significant effect on anticipated regret, and the effect was again mediated by perceived justifiability. Decision justification theory thus appears to provide a better account of anticipated regret intensity in this context than does norm theory.     

Affective and health-related outcome expectancies for physical activity in older adults

This study tests the effects of affective and health-related outcome expectancies on physical exercise, assuming stronger direct and indirect (via intention) effects from affective outcome expectancy to physical exercise than from health-related outcome expectancy to exercise. Physical exercise and social cognitive variables were assessed at baseline, and 6- and 12-month follow-up in 335 older adults (60–95 years of age). Applying structural equation modelling, there was a direct effect from affective, but not from health-related outcome expectancy on intentions and behaviour. Also, the indirect effect from self-efficacy on physical exercise via affective outcome expectancy was significant, whereas the mediation via health-related outcome expectancy was not. These findings emphasise the relative importance of affective versus health-related outcome expectancies in predicting intentions and physical exercise in older adults and highlight the importance to separate these facets at a conceptual level to enhance both theory development and health promotion.
