Volatile Reasons

I argue for the existence of a category of practical reasons which I call ‘Deliberation-Volatile Reasons’ or ‘DVRs’. DVRs have the distinguishing feature that their status as reasons for action is diminished when they are weighed in deliberation by the agent. I argue that DVRs are evidence of ‘deliberative blind spots’. I submit that an agent manifests a peculiar kind of practical irrationality in so far as she endeavours to find a deliberative path to what she has reason to do, when the discovery of such a path renders the destination inaccessible.     

Cue competition effects in the planarian

The learning abilities of planarian worms (Dugesia tigrina) were assessed by using a number of Pavlovian conditioning paradigms. Experiment 1 showed that planaria were susceptible to basic conditioning in that they readily developed a conditioned response to a change in ambient luminance when it was consistently paired with an electric shock over a number of trials. In Experiment 2, the change in luminance was presented in a compound with a vibration stimulus during conditioning. Subsequent tests revealed poor conditioning of the elements compared with control groups in which the animals were conditioned in the presence of the elements alone, an instance of overshadowing. In Experiment 3, pre-training of one of the elements before compound conditioning resulted in blocking of learning about the other element. These results add to other studies that have reported cue competition effects in animal species belonging to different phyla (chordate, mollusk, arthropod), suggesting that learning in these phyla could be ruled by similar principles. The results are discussed adopting an evolutionary-comparative approach.     

Burnout and its relations with basic psychological needs and motivation among athletes: A systematic review and meta-analysis

ObjectivesThe present study is a review on studies about the relationships between the three basic psychological needs/motivational regulations (i.e., amotivation, controlled regulation, extrinsic autonomous regulation, and intrinsic motivation) and burnout.DesignA systematic review and meta-analysis.MethodStudies were identified through five electronic databases and manual search using combinations of three groups of keywords. Three inclusion criteria were then used to screen the searched articles.ResultsEighteen studies met the inclusion criteria and these studies varied considerably in terms of their study characteristics (e.g., characteristics of participants, study designs, and outcome measures). The results also showed that the three basic psychological needs, intrinsic motivation, extrinsic autonomous regulation, and amotivation had small to large effects on predicting global burnout and its three dimensions. However, controlled regulation showed no or weak correlations with the burnout subscales.ConclusionsSelf-determination theory was generally supported in explaining athlete burnout.     

The Blood of Jesus in revival theology and the contemporary Church with particular reference to the East African Revival and Roy Hession

One of the most common phrases heard in testimony, preaching, and song during the East African Revival (EAR) was the phrase ‘The Blood of Jesus Christ’. Taken from a rich biblical heritage, this phrase encapsulates a wide range of ideas concerning the work of the cross and the power of forgiveness in a believer's life. Whilst, as will be noted, the use of The Blood has been common to many revivals, this article examines especially the theology behind this phrase by looking at the most prominent of the EAR authors – Roy Hession. It investigates seven different applications of The Blood in a believer's life: The Blood as a testament that sin is forgiven, The Blood as cleansing the conscience, The Blood as victory over despair, The Blood as the remover of shame, The Blood as washing away sin, The Blood as the gateway of the Holy Spirit, and finally The Blood as the source of true fellowship. The theology of The Blood has a long history of use in the Church but it also comes with difficulties. To this end the article will investigate the legitimacy of the practice often found in Africa and some Pentecostal circles of invoking The Blood as protection against the demonic. The article closes by considering the reasons why speaking of The Blood in church can be uncomfortable yet is paradoxically of vital importance to revival.     

A Response to Patricia A. Williams' “The Fifth R: Jesus as Evolutionary Psychologist”

Panentheism has recently become a widely accepted and appreciated concept among scholars in the science-theology dialogue, and its theological repercussions have been discussed to great extent. Yet, there remains to be studied in more detail the notion of the philosophical foundations of the term. A prominent gap in our understanding of these foundations is the potential similarity between the metaphysics of Hegel and Whitehead, their understanding of the transcendence and immanence of God, and their respective versions of panentheism. In this article, I present a critical reflection on the possible resemblance between process thought and Hegelian metaphysics and philosophy of God. In the last section I refer to those who use panentheism within the science-theology dialogue. I try to specify which of the two versions of panentheism, that of Hegel or Whitehead, is more popular among those scholars.     

MEETING CALENDAR

Abstract

Stress, coping, and appraisal were explored in order to better understand the factors associated with smoking cessation. Employees from 61 worksites received one of three programs which incorporated the use of self-help manuals, incentives, social support groups, and cognitive-behavioral techniques. Results indicated successful quitters perceived less stress in their lives, used more problem-focused coping and less emotion-focused coping, and perceived more control over their stressors than participants who were not able to quit smoking.     

Inhibition of return promotes stop-signal inhibition by delaying responses

Inhibition of return (10R) refers to a mechanism that slows response times (RTs) to detect, localize, or discriminate a target that is presented at a location previously occupied by an irrelevant peripheral cue. Generally, the slowing of RTs is described as a negative effect on responding that is believed to promote searching to new locations. In this report, we consider whether IOR might benefit performance when the goal is to prevent a prepared response. Using the stop-signal paradigm, we show that IOR improved the ability to inhibit a prepared response by delaying responses to the target. Thus, in addition to aiding visual search, IOR may also provide an opportunity for the adjustment of decisions and behaviour in accordance with the demands of a dynamic environment.     

Objective assessment of the functional role of spike train correlations using information measures

The functional role of correlations between neuronal spike trains remains strongly debated. This debate partly stems from the lack of a standardized analysis technique capable of accurately quantifying the role of correlations in stimulus encoding. We believe that information theoretic measures may represent an objective method for analysing the functional role of neuronal correlations. Here we show that information analysis of pairs of spike trains allows the information content present in the firing rate to be disambiguated from any extra information that may be present in the temporal relationships of the two spike trains. We validate and illustrate the method by applying it to simulated data with variable degrees of known synchrony, and by applying it to recordings from pairs of sites in the primary visual cortex of anaesthetized cats. We discuss the importance of information theoretic analysis in elucidating the neuronal mechanisms underlying object identification.
