Boring Infinite Descent

In formal ontology, infinite regresses are generally considered a bad sign. One debate where such regresses come into play is the debate about fundamentality. Arguments in favour of some type of fundamentalism are many, but they generally share the idea that infinite chains of ontological dependence must be ruled out. Some motivations for this view are assessed in this article, with the conclusion that such infinite chains may not always be vicious. Indeed, there may even be room for a type of fundamentalism combined with infinite descent as long as this descent is “boring,” that is, the same structure repeats ad infinitum. A start is made in the article towards a systematic account of this type of infinite descent. The philosophical prospects and scientific tenability of the account are briefly evaluated using an example from physics.     

On the function of a ‘break’ within the psychoanalytic double session

This article considers theoretical and clinical implications of the practice of ‘double sessions’ as defined by two consecutive sessions of psychotherapy divided by a 10-minute break. Limited existing literature of ‘double sessions’ is critiqued and the therapeutic significance of the 10-minute break provides the focus for this article with reference to the Lacanian practice of ‘scansion’. The author draws on relevant therapeutic experience and case material to elucidate the potential benefits of the introduction of double sessions with particular client groups. It is argued that the break provides the opportunity to access often hidden archaic defences as the effects of rupture and reconnection are worked through. Equally, the separation of the break allows the patient's immediate associations following the end of the first session to be brought immediately back into the work. The practice is problematised in relation to potential contraindications with particular patient groups and this, in turn, elucidates the conceptual differences between Freudian/Lacanian and object relations traditions.     

L’invention managériale : une compétence cardinale pour les situations organisationnelles complexes

This study models “the manager invention”, cardinal skill to face the complex, contradictory, unpredictable socio-organizational reality. The works of Morin (on 1986, 1999, 2001) on the processes of the complex thought and those of Detienne and Vernant (1974), of Frontisi-Ducroux (1975) and Dejours (1993) about the mètis or practice intelligence serve us as theoretical supports, the analysis of contents of managers' narratives of empirical supports. The principles of a complex cognition (dialogical of the contradictory, complementarity of opposite, logic of the inclusive third) support the creative strategies of the managers : guile rather than force, diversion, bypassing, double position, happy medium, oblique speeches.     

Causal uncertainty and metacognitive inferences about goal attainment

These four studies investigated G. Weary and J. A. Edwards’ (1996) hypothesis that causal uncertainty feelings serve as input to perceivers regarding the adequacy of their causal knowledge and thus determine the amount of processing accorded a given task. Participants worked on a task until they had satisfied an assigned stop rule. In three experiments, high causally uncertain people processed more information under a sufficiency of information rule and less under an enjoyment rule, whereas low causally uncertain people generally did not differentiate between the rules. In the last experiment, low causally uncertain people exhibited a similar pattern to the chronic causally uncertain individuals in the first experiments, but only after their causal uncertainty beliefs and feelings had been primed.     

Conceptualising Decadent Technology: A Case Study of Path Dependence in Radiotherapy

Abstract

Large-scale investments in health technologies often have limited evidence for effectiveness when first introduced. Nevertheless, professional and public discourses often present the advantages of such investments, with unknown risks, as necessary and entailing significant improvement. Such discourses are evident with the introduction of the Linac Adapted Conebeam Imager (LACI), introduced to improve the accuracy of radiotherapy treatments. From one perspective, the introduction of such technologies can be considered to be decadent since there is limited, if any, evidence of improvement of current standards and procedures, yet they are promoted as the latest and best technologies for solving societal problems. Connecting the concepts of decadence to those of path dependence, through the case of the LACI, enables the exploration of the ‘technical interrelatedness’ of technological changes. Building on the concept of path dependence, it is possible to demonstrate how introducing a closely related technology does not only become a low-risk course of action. Rather change is demanded (but not determined) as well as potential alternative systems being obscured. With decadent technologies, any future changes are not only dependent upon past introductions; but also they create a need for future changes. Such a view demonstrates how these technologies may not necessarily offer any improvements, but rather contribute to the creation of ongoing demand for unproven technologies. As a result they may encourage the introduction of increasingly complex technologies.     

基于易感人格的药物成瘾者工作记忆对执行控制功能的调节作用

为了解工作记忆在易感性人格对药物成瘾者执行控制功能和抑制性影响过程中的调节作用,采用BIS和SSS量袁以及连续操作测验（CPT）、2-back任务、威斯康星卡片分类任务（WCST）对150名药物成瘾者和100名年龄、性别及智商相匹配的非药物成瘾者实施冲动性人格、认知控制功能测试。结果发现在2-back任务正确率（工作记忆）高低不同的情况下,注意冲动性人格特质得分对执行控制功能会产生不同的影响。这说明工作记忆在冲动性人格对抑制性的影响中具有调节作用。     

Psychological treatment of hypnotic-dependent insomnia in a primarily older adult sample

Objective

This study tested cognitive behavior therapy (CBT) in hypnotic-dependent, late middle-age and older adults with insomnia.

Method

Seventy volunteers age 50 and older were randomized to CBT plus drug withdrawal, placebo biofeedback (PL) plus drug withdrawal, or drug withdrawal (MED) only. The CBT and PL groups received eight, 45 min weekly treatment sessions. The drug withdrawal protocol comprised slow tapering monitored with about six biweekly, 30 min sessions. Assessment including polysomnography (PSG), sleep diaries, hypnotic consumption, daytime functioning questionnaires, and drug screens collected at baseline, posttreatment, and 1-year follow-up.

Results

Only the CBT group showed significant sleep diary improvement, sleep onset latency significantly decreased at posttreatment. For all sleep diary measures for all groups, including MED, sleep trended to improvement from baseline to follow-up. Most PSG sleep variables did not significantly change. There were no significant between group differences in medication reduction. Compared to baseline, the three groups decreased hypnotic use at posttreatment, down 84%, and follow-up, down 66%. There was no evidence of withdrawal side-effects. Daytime functioning, including anxiety and depression, improved by posttreatment. Rigorous methodological features, including documentation of strong treatment implementation and the presence of a credible placebo, elevated the confidence due these findings.

Conclusions

Gradual drug withdrawal was associated with substantial hypnotic reduction at posttreatment and follow-up, and withdrawal side-effects were absent. When supplemented with CBT, participants accrued incremental self-reported, but not PSG, sleep benefits.     

Reference-dependent sympathy

Natural disasters and other traumatic events often draw a greater charitable response than do ongoing misfortunes, even those that may cause even more widespread misery, such as famine or malaria. Why is the response disproportionate to need? The notion of reference dependence critical to Prospect Theory (Kahneman & Tversky, 1979) maintains that self-utility, or benefit to self, is not absolute level of wealth but rather gain or loss relative to a reference point. Four studies show that sympathy (Study 1), dictator offers (Study 2), and judgments of deservingness (Study 3a) are reference-dependent: people respond greater to victims of loss than to victims of chronic conditions. This tendency goes away when people evaluate victims in comparison (Study 3b) and when evaluating affect-poor “statistical victims”, as compared to affect-rich “identifiable victims” (Study 4). Together, these results shed light on seemingly irrational patterns of humanitarian aid.     

To err again is human: exploring a bidirectional relationship between pressure and performance failure feedback

ABSTRACT

Background and Objectives: While the potentially negative effects of pressure on skilled performance have been well studied in laboratory-based research, theoretically driven questions based on real-world performance data are lacking.

Design: We aimed to test the predictions of the newly developed Attentional Control Theory: Sport (ACTS), using archived play-by-play data from the past seven seasons of the National Football League (American Football).

Methods: An additive scoring system was developed to characterize the degree of pressure on 212,356 individual offensive plays and a Bayesian regression model was used to test the relationship between performance, pressure and preceding negative outcomes, as outlined in ACTS.

Results: There was found to be a clear increase in the incidence of failures on high pressure plays (odds ratio?=?1.20), and on plays immediately following a previous play failure (odds ratio?=?1.09). Additionally, a combined interactive effect of previous failure and pressure indicated that the feedback effect of negative outcomes was greater when pressure was already high (odds ratio?=?1.10), in line with the predictions of ACTS.

Conclusions: These findings reveal the importance of exploring momentary changes in pressure in real-world sport settings, and the role of failure feedback in influencing the pressure-performance relationship.
