The Sad Truth: Optimism, Pessimism, and Pragmatism

Pragmatists (such as William James) recommend optimism as a successful strategy, and recent psychological research has confirmed its value. But optimism comes at a price: optimists are less accurate in their assessments and expectations than are pessimists. Thus optimism 'proves itself to be good in the way of belief', and by pragmatic standards should count as true; but that makes the accuracy costs of optimism invisible (the problem is only exacerbated by Rorty's recommendation that pragmatists stop speaking of truth altogether). The problem prevents pragmatists from offering a Darwinian explanation of why pessimism survives, and also blocks any pragmatist account of the well-documented and highly successful exploratory behavior of many animal species.     

Building self-control strength: Practicing self-control leads to improved self-control performance

Self-control performance may be improved by the regular practice of small acts of self-control.Ninety-two adults’ self-control capacity was assessed using the stop signal paradigm before they started practicing self-control and again at the end of 2 weeks. Participants who practiced self-control by cutting back on sweets or squeezing a handgrip exhibited significant improvement in stop signal performance relative to those who practiced tasks that did not require self-control. Participants who did not practice self-control believed that the tasks should improved self-control, engaged in tasks that were effortful and made self-control salient, but did not actually require self-control. Supplemental analyses suggested that only practicing self-control built self-control capacity; the improved outcomes cannot be explained by self-fulfilling prophecies, increased self-efficacy or awareness of self-control. The results may have implications for understanding the development of self-control in both children and adults, as well as clinical implications for treating disorders that involve low self-control.     

Flexibility,friendship, and family

This article is concerned with the impact of late modernity on patterns of solidarity in friend and family relationships. It takes as its starting point the transformations in partnership, family, and household formation and dissolution that have been occurring in Western societies since the 1970s. Accepting these shifts as indicative of the greater freedoms people now have over the construction of their personal relationships and social networks, the article examines the degree to which the domains of family and friendship are merging. Its principal argument is that despite increased flexibility in the construction of personal life, including diversity in the prioritization of different relationships, at a cultural level clear boundaries exist between family and friendship ties.     

Commitment, choice and self-control

When offered a choice (Choice Y) between a small immediate reward (2-sec exposure to grain) and a large reward (4-sec exposure to grain) delayed by 4 sec, pigeons invariably preferred the small, immediate reward. However, when offered a choice (Choice X) between a delay of T seconds followed by Choice Y and a delay of T seconds followed by restriction to the large delayed reward only, the pigeon's choice depended on T. When T was small, the pigeons chose the alternative leading to Choice Y (and then chose the small, immediate reward). When T was large, the pigeons chose the alternative leading to the large delayed reward only. The reversal of preference as T increases is predicted by several recent models for choice between various amounts and delays of reward. The preference for the large delayed alternative with long durations of T parallels everyday instances of advance commitment to a given course of action. Such commitment may be seen as a prototype for self-control.     

Truthier Than Thou: Truth,Supertruth and Probability of Truth

Different formal tools are useful for different purposes. For example, when it comes to modelling degrees of belief, probability theory is a better tool than classical logic; when it comes to modelling the truth of mathematical claims, classical logic is a better tool than probability theory. In this paper I focus on a widely used formal tool and argue that it does not provide a good model of a phenomenon of which many think it does provide a good model: I shall argue that while supervaluationism may provide a model of probability of truth, or of assertability, it cannot provide a good model of truth—supertruth cannot be truth. The core of the argument is that an adequate model of truth must render certain connectives truth‐functional (at least in certain circumstances)—and supervaluationism does not do so (in those circumstances).     

Procrastination,deadlines, and performance: self-control by precommitment

Procrastination is all too familiar to most people. People delay writing up their research (so we hear!), repeatedly declare they will start their diets tomorrow, or postpone until next week doing odd jobs around the house. Yet people also sometimes attempt to control their procrastination by setting deadlines for themselves. In this article, we pose three questions: (a) Are people willing to self-impose meaningful (i.e., costly) deadlines to overcome procrastination? (b) Are self-imposed deadlines effective in improving task performance? (c) When self-imposing deadlines, do people set them optimally, for maximum performance enhancement? A set of studies examined these issues experimentally, showing that the answer is "yes" to the first two questions, and "no" to the third. People have self-control problems, they recognize them, and they try to control them by self-imposing costly deadlines. These deadlines help people control procrastination, hit they are not as effective as some externally imposed deadlines in improving task performance.     

Alcohol, sexual arousal, and self-control

The effects of alcohol on self-regulation were investigated using delay of gratification for viewing time for an erotic film as the primary dependent measure. Other measures included reflection--impulsivity, locus of control, sexual-guilt scores, and continuous recording of subject's penile tumescence. Using a balanced placebo design, subjects were led to believe that they had consumed an alcoholic or a nonalcoholic beverage, and half of each of these two groups received either alcohol or tonic water. In addition, the effects of three doses of alcohol (placebo, low dose, high dose) were investigated. Instructional set, regardless of drink content, resulted in longer delay times and increased thoughts with sexual content. Although there was no significant relation between increasing dose of alcohol and delay time, there was an interaction between locus-of-control scores and alcohol dose. Externalizers showed an inverse linear relation between increasing dose of alcohol and delay time. Internalizers showed the opposite trend. Implications for the self-regulation of sexual behavior under the influence of alcohol are discussed.     

Impulsivity,self-control,and hypnotic suggestibility

Hypnotic responding might be due to attenuated frontal lobe functioning after the hypnotic induction. Little is known about whether personality traits linked with frontal functioning are associated with responsiveness to hypnotic suggestions. We assessed whether hypnotic suggestibility is related to the traits of self-control and impulsivity in 154 participants who completed the Brief Self-Control Scale, the Self-Regulation Scale, the Barratt Impulsiveness Scale (BIS-11), and the Harvard Group Scale of Hypnotic Susceptibility (HGSHS:A). BIS-11 non-planning impulsivity correlated positively with HGSHS:A (Bonferroni-corrected). Furthermore, in the best model emerging from a stepwise multiple regression, both non-planning impulsivity and self-control positively predicted hypnotic suggestibility, and there was an interaction of BIS-11 motor impulsivity with gender. For men only, motor impulsivity tended to predict hypnotic suggestibility. Hypnotic suggestibility is associated with personality traits linked with frontal functioning, and hypnotic responding in men and women might differ.     

Drugs, mental instruments, and self-control

The instrumental model offered by Müller & Schumann (M&S) is broadened to apply not only to drugs, but also to other methods of self-control, including the use of mental constructs to produce adaptive changes in behavior with the possibility of synergistic interactions between various instruments.     

Non-psychological weakness of will: self-control,stereotypes, and consequences

Prior work on weakness of will has assumed that it is a thoroughly psychological phenomenon. At least, it has assumed that ordinary attributions of weakness of will are purely psychological attributions, keyed to the violation of practical commitments by the weak-willed agent. Debate has recently focused on which sort of practical commitment, intention or normative judgment, is more central to the ordinary concept of weakness of will. We report five experiments that significantly advance our understanding of weakness of will attributions by showing that the ordinary concept of weakness of will is less thoroughly psychological than the philosophical debate has assumed. We begin by showing that a sizable minority of people attribute weakness of will even in the absence of a violated commitment (Experiment 1). We then show that weakness of will attributions are sensitive to two important non-psychological factors. First, for actions stereotypically associated with weakness of will, the absence of certain commitments often triggers weakness of will attributions (Experiments 2–4). Second, the quality of an action’s outcome affects the extent to which an agent is viewed as weak-willed: actions with bad consequences are more likely to be viewed as weak-willed (Experiment 5). Our most important finding is that the ordinary concept of weakness of will is sensitive to two non-psychological factors and is thus much broader than philosophers have thus far imagined. We conclude by suggesting a two-tier model that unites our findings with traditional philosophical theorizing about weakness of will.     

Anxiety, self-control and shooting performance

55 rifle shooters were administered state-trait anxiety and self-control questionnaires. Shooting performance was recorded on 7 competitive occasions. Analysis indicated shooting performance is dependent more on anxiety state than on anxiety trait and self-control. Highly skilled shooters were less anxious and performed better across all competitions than moderately skilled shooters but did not differ on self-control and anxiety trait. The assumption that increased anxiety negatively affects performance through the mediation of self-control should be further studied.     

Social skills, friendship and happiness: a cross-cultural investigation

The present study investigated the associations between social skills, friendship quality, and happiness, and tested a mediational model positing that friendship quality would mediate the relationship between social skills and happiness among American and Malaysian college students. Although American students reported significantly higher levels of psychosocial well-being than Malaysian students, the study variables were positively associated with each other in both cultures. More importantly, findings supported the proposed model in both groups. Results suggest that part of the reason why social skills are associated with positive psychological well-being is because of friendship experiences. Overall, the findings of the present study reinforce, extend and cross-culturally generalize the presumed benefits of social skills in positive well-being elaborated by Segrin and Taylor (2007). The authors also provided suggestions for future research.     

Positive affect and self-control: Attention to self-control demands mediates the influence of positive affect on consecutive self-control

Positive affect (PA) can either improve or impair self-control performance, depending on whether two tasks are dissimilar, and thus require flexible releasing and switching, or similar, which requires stable maintenance. The present study suggests that this effect is mediated by attentional shifts. The authors found that participants under PA, who performed on two dissimilar tasks and had to switch to a new response dimension, were less attentive to distracting information compared to neutral affect (NE), leading to better performance. In contrast, participants under PA who did not have to switch, were more attentive to distracting information compared to participants under NE. These findings highlight the opposite effects of PA on consecutive self-control.     

The Truth, Goodness, and Beauty of Darwinism

As a young proponent of "creation science," I rejected Darwinian biology as false, bad, and ugly. Now I defend Darwinism as true, good, and beautiful. Moreover, I now see Darwinism as compatible with the natural piety that arises as one moves from nature to nature's God.     

The ethics of belief: doxastic self-control and intellectual virtue

Most of the literature on doxastic voluntarism has concentrated on the question of the voluntariness of belief and the issue of how our actual or possible control of our beliefs bears on our justification for holding them and on how, in the light of this control, our intellectual character should be assessed. This paper largely concerns a related question on which less philosophical work has been done: the voluntariness of the grounding of belief and the bearing of various views about this matter on justification, knowledge, and intellectual virtue. In part, my concern is the nature and extent of our voluntary control over our responses to reasons for believing—or over what we take to be such reasons. This paper provides a partial account of such control and, on the basis of the account, will clarify the criteria for appraising intellectual virtue.
