The Persistent Interlocutor

A Persistent Interlocutor (PI) is someone who, in argumentative contexts, does not cease to question her opponent’s premises. The epistemic relevance of the PI has been debated throughout the history of philosophy. Pyrrhonians famously claim that our inability to dialectically vindicate our claims against a PI implies scepticism. Adam Leite disagrees (2005). Michael Resorla argues that the debate is based on a false premise (2009). In this paper, I argue that these views all fail to accurately account for the epistemic relevance of the PI. I then briefly present an account that aims to do better in this regard, based on the modal notion of safety. On the account proposed, the PI does not violate epistemic or dialectical norms. Rather, her behaviour tends to be epistemically perverse in the sense that it wastes cognitive resources. Perhaps surprisingly, this defect turns out not to be unique to the PI.

     

论错觉的逻辑

对于有关常识和诸如“理性”、“真理”和“实在”这样的哲学思想的主要范畴来说,错觉是一种异乎寻常的检验案例。我的目标是,通过与弗洛伊德的遗产和20世纪最引人注目的精神病学研究成果进行某种交锋,分析这种错觉所具有的各种富有悖论色彩的形式,从而阐明构成了它那些特定的时间化、概念化和论证样态之基础,并且为这些样态确定方向的逻辑。就英语而言,人们也许是在“幻觉”的意义上使用delusion(错觉)这个术语的,不过,它也可以被用来表示我们在罗曼诸语言之中称之为“delirio”或者“d啨lire”(这两个外来语在这里均指“迷狂”之意,前者是…     

Too exhausted to go to bed: Implicit theories about willpower and stress predict bedtime procrastination

While most people are aware of the importance of sleep for their health, well-being, and performance, bedtime procrastination is a pervasive phenomenon that can be conceptualized as a case of self-control failure (Kroese et al., Frontiers in Psychology, 5, 2014, 1). Two daily diary studies (N₁ = 185, N₂ = 137) investigated beliefs about willpower and stress as interactive predictors of bedtime procrastination. Beliefs about willpower capture whether people think of their willpower as limited resource that gets easily depleted (limited theory) or as something that remains regardless of previous acts of self-control (non-limited theory). Results show that after a stressful day, people with a limited versus non-limited theory procrastinate more on going to bed, while there is no difference in bedtime procrastination on less stressful days. Thus, ironically, limited theorists who should be more concerned with recovering their resources after a stressful day sleep less the following night.     

Visual effects in picture and word categorization

Two experiments are reported in which participants categorized stimuli as belonging or not belonging to the category of fruits. Blocks of pictures and words were used, with items referring to exemplars having either high or low intercategory visual similarity and/or semantic relatedness. For both pictures and words, response time was longer in the semantically related conditions than in the unrelated condition. Furthermore, there was a strong effect of visual similarity for pictures but not for words when semantic relatedness was held constant: Participants took longer to classify pictures of fruits when these were mixed with visually similar vegetables than when they were mixed with visually dissimilar vegetables. Reducing the stimulus visibility by adding a dot pattern had an additive effect for words but an interactive effect for pictures. The results are explained in terms of a unique locus for category decisions about pictures and words.     

Evidence for Opportunity Cost Neglect in the Poor

People often neglect opportunity costs: They do not fully take into account forgone alternatives outside of a particular choice set. Several scholars have suggested that poor people should be more likely to spontaneously consider opportunity costs, because budget constraints should lead to an increased focus on trade‐offs. We did not find support for this hypothesis in five high‐powered experiments (total N = 2325). The experiments used different products (both material and experiential) with both high and low prices (from $8.50 to $249.99) and different methods of reminding participants of opportunity costs. High‐income and low‐income participants showed an equally strong decrease in willingness to buy when reminded of opportunity costs, implying that both the rich and the poor neglect opportunity costs. © 2017 The Authors Journal of Behavioral Decision Making Published by John Wiley & Sons Ltd.     

Back to “the Future”: Evidence of a Bifactor Solution for Scores on the Consideration of Future Consequences Scale

Despite its widespread use, disagreement remains regarding the structure of the Consideration of Future Consequences Scale (CFCS). In particular there is disagreement regarding whether the scale assesses future orientation as a unidimensional or multidimensional (immediate and future) construct. Using 2 samples of high school students in the United Kingdom, 4 models were tested. The totality of results including item loadings, goodness-of-fit indexes, and reliability estimates all supported the bifactor model, suggesting that the 2 hypothesized factors are better understood as grouping or method factors rather than as representative of latent constructs. Accordingly this study supports the unidimensionality of the CFCS and the scoring of all 12 items to produce a global future orientation score. Researchers intending to use the CFCS, and those with existing data, are encouraged to examine a bifactor solution for the scale.     

Muslim Experiential Religiousness in Pakistan: Meaning in Life,General Well-Being and gender differences

This study examined relationships of Muslim spirituality with positive psychology in Pakistan. In a sample of 200 university students and community members, the spirituality of Muslim Experiential Religiousness displayed direct linkages with Meaning in Life and General Well-Being subscales. Muslim Experiential Religiousness also correlated positively with single-item assessments of the Intrinsic, Extrinsic Personal, and Extrinsic Social Religious Orientations and explained the relationships of these religious motivations with General Life Satisfaction. Women scored higher than men on Muslim Experiential Religiousness, but at least some linkages of Muslim spirituality with positive psychology were more robust in men. As in other recent investigations, these data confirmed Muslim Experiential Religiousness as a valid index of Muslim spirituality beyond the Iranian cultural context in which it was developed.     

Discrepancies Between Implicit and Explicit Motivation and Unhealthy Eating Behavior

ABSTRACT Many people change their eating behavior as a consequence of stress. One source of stress is intrapersonal psychological conflict as caused by discrepancies between implicit and explicit motives. In the present research, we examined whether eating behavior is related to this form of stress. Study 1 (N=53), a quasi‐experimental study in the lab, showed that the interaction between the implicit achievement motive disposition and explicit commitment toward an achievement task significantly predicts the number of snacks consumed in a consecutive taste test. In cross‐sectional Study 2 (N=100), with a sample of middle‐aged women, overall motive discrepancy was significantly related to diverse indices of unsettled eating. Regression analyses revealed interaction effects specifically for power and achievement motivation and not for affiliation. Emotional distress further partially mediated the relationship between the overall motive discrepancy and eating behavior.     

The Effects of Uncontrollable, Unpredictable Aversive and Appetitive Events: Similar Effects Warrant Similar, but not Identical, Explanations?

Exposure to uncontrollable, unpredictable appetitive events produces a variety of cognitive debilitations and vegetative changes, as does exposure to uncontrollable, unpredictable aversive events. Similarities include impaired escape from aversive events, impaired discrimination, finicky consumption, analgesia, and body weight loss. However, in stark contrast, uncontrollable aversive stress causes reduced motor activity where as similar appetitive treatment does not; aversively induced debilitation is causally related to energy regulation, whereas the appetitively induced effects are not. Parallel mechanisms are suggested to explain these effects in terms of a revised anxiety account of the aversive effects, and a frustration account of the appetitive effects. Finally, factors likely to limit important research to resolve the many remaining issues are identified: negative presentation of animal research, political decision making, and ignorance and fear in committees which review the ethics of research.     

Muslim Distress Mobilization Hypothesis: complex roles of Islamic Positive Religious Coping and Punishing Allah Reappraisal in Iranian students

Muslim religious coping may include distress mobilisation effects that explain why adaptive and maladaptive forms of religious coping correlate positively rather than nonsignificantly, as they usually do in the West. In this study, 147 Iranian university students responded to Islamic Positive Religious Coping (IPRC) and Punishing Allah Reappraisal (PAR) Scales along with Religious Orientation, Perceived Stress, and mental health measures. IPRC and PAR correlated positively, and procedures accounting for their covariance were essential in disambiguating their implications. IPRC predicted stronger Intrinsic and Extrinsic Personal Religious Orientations, but PAR displayed no relationship with religious motivations. PAR pointed toward broadly negative mental health influences with IPRC displaying limited ties with adjustment. PAR partially mediated some Perceived Stress relationships with poorer mental health. These data offered some support for a Muslim Distress Mobilization Hypothesis, but also uncovered issues that require further clarification.
