The Lucretian Puzzle and the Nature of Time

If a person’s death is bad for him for the reason that he would have otherwise been intrinsically better off, as the Deprivation Approach says, does it not follow that his prenatal nonexistence is bad for him as well? Recently, it has been suggested that the “A-theory” of time can be used to support a negative answer to this question. In this paper, I raise some problems for this approach.     

Flat intentions – crazy dispositions?

Future-directed intentions, it is widely held, involve behavioral dispositions. But of what kind? Suppose you now intend to Φ at future time t. Are you thereby now disposed to Φ at t no matter what? If so, your intention disposes you to Φ even if around t you will come to believe that Φ-ing would be crazy. And would not that be a crazy intention to have? – Like considerations have led Luca Ferrero and others to believe that only intentions with strong internal conditions are capable of rationality. This paper explores in how far a broadly dispositional view of intention supports their claims. Its first point will come as a surprise: Intentions indeed involve dispositions toward follies in plenty. Natural objections against this bizarre-sounding claim are shown to fail, and standard counterfactual analyses of disposition locutions are shown to underpin it further. However, since the dispositions at issue are pro tanto dispositions, the consequences are not as odd as might be expected: When hedged by reasonable habits to reconsider one’s intentions, dispositions toward follies do not entail any actual crazy behavior. On balance, unconditional intention is therefore found rational after all. Dispositions toward crazy actions need not be crazy dispositions.     

Consideration of the BDNF gene in relation to two phenotypes: hoarding and obesity

The gene coding for the brain derived neurotrophic factor (BDNF) has emerged as an interesting candidate for multiple brain and brain disorder-related phenomena. The primary aim of the present investigation was to consider the relationship between the BDNF Val66Met variant and two phenotypes: compulsive hoarding as a symptom dimension of obsessive-compulsive disorder (OCD), and body mass index (BMI). We examined the BDNF gene in a large (N=301) clinical sample of probands with OCD. Participants were classified as hoarding or nonhoarding using a strict, multimeasure grouping approach. Results revealed that the Val/Val genotype was linked with hoarding classification and more severe hoarding behaviors, as well as greater BMI levels. Hoarding status was also associated with greater BMI scores, with individuals in the hoarding group being far more likely to be classified as obese compared with the nonhoarding group. Our findings may provide a distinct avenue through which hoarding and BMI could be linked. These findings are suggestive of a complex gene, body weight, and psychopathology relationship wherein a primitive, survival "thrifty gene" strategy may be conserved and represented in a subgroup of humans manifesting severe hoarding symptoms.     

Keeping one's options open: The detrimental consequences of decision reversibility

People generally prefer to have the opportunity to revise their decisions. Surprisingly however, research has shown that keeping one's options open yields lower satisfaction with the decision outcome (Gilbert & Ebert, 2002). Two studies aimed to gain more insight into the detrimental consequences of decision reversibility and the cognitive processes underlying decision reversibility. Building upon literature on goal fulfillment we hypothesized and found in a first experiment that as long as decisions are still open to change, accessibility of decision-related constructs is increased compared to neutral constructs. A second experiment demonstrated that decision reversibility undermines working memory capacity. Moreover participants experienced higher regret after having made a reversible decision, an effect that was mediated by decreased working memory capacity. The study set implies that reversible decisions yield lower working memory capacity because people continue to think about the, still relevant, choice options. In the end this might increase dissatisfaction with the decision and regret.     

Stepping back to see the big picture: when obstacles elicit global processing

Can obstacles prompt people to look at the "big picture" and open up their minds? Do the cognitive effects of obstacles extend beyond the tasks with which they interfere? These questions were addressed in 6 studies involving both physical and nonphysical obstacles and different measures of global versus local processing styles. Perceptual scope increased after participants solved anagrams in the presence, rather than the absence, of an auditory obstacle (random words played in the background; Study 1), particularly among individuals low in volatility (i.e., those who are inclined to stay engaged and finish what they do; Study 4). It also increased immediately after participants encountered a physical obstacle while navigating a maze (Study 3A) and when compared with doing nothing (Study 3B). Conceptual scope increased after participants solved anagrams while hearing random numbers framed as an "obstacle to overcome" rather than a "distraction to ignore" (Study 2) and after participants navigated a maze with a physical obstacle, compared with a maze without a physical obstacle, but only when trait (Study 5) or state (Study 6) volatility was low. Results suggest that obstacles trigger an "if obstacle, then start global processing" response, primarily when people are inclined to stay engaged and finish ongoing activities. Implications for dealing with life's obstacles and related research are discussed.     

He just wants to play: how goals determine the influence of violent computer games on aggression

Generally, the accessibility of goal-related constructs is inhibited upon goal fulfillment. In line with this notion, the current studies explored whether violent computer games may reduce relative accessibility of aggression if the game involves the fulfillment of an aggressive goal. Specifically, in Study 1, participants who watched a trailer for a violent computer game that fulfilled the goal of venting anger showed less relative accessibility of aggression compared to participants who watched the trailer without goal fulfillment. In Study 2, actually playing a violent computer game to vent anger also decreased the relative accessibility of aggression compared to a control condition in which the game was played without such a goal. Lastly, in Study 3, the relative accessibility of aggression was reduced after playing a violent computer game for participants who reported a high general tendency to vent their anger.     

Two-Year Findings from a National Effectiveness Trial: Effectiveness of Behavioral and Non-Behavioral Parenting Programs

Long-term follow-up studies of selective parent training (PT) programs are scarce, particularly in the case of effectiveness trials conducted within regular care settings. This study evaluated the 2-year effects of 4 programs: Comet, Incredible Years, Cope, and Connect and differences in the rate of change among programs were investigated using Latent Growth Modeling (LGM). Participants were parents who had sought help at 30 local service sector units (e.g., child psychiatric clinics and social services centers) for major problems in managing their children’s externalizing behavior. Parents of 749 children (63 % boys) with moderate levels of externalizing behavior, aged 3–12, were randomized to one of the 4 PT programs. Assessments included parent-reported measures of child externalizing, hyperactivity and inattention, as well as parenting practices, sense of competence, and parents’ stress and depressive symptoms. At 2-year follow-up, there were no differences in any of the child outcomes among the programs. All programs had reduced externalizing behaviors with large effect sizes (d = 1.21 to d = 1.32), and negative parenting practices with moderate to large effect sizes (d = 0.49 to d = 0.83). LGM analyses showed that the 2 behavioral programs, Comet and Incredible Years, produced more rapid reductions in externalizing behavior during the course of the intervention than the non-behavioral program, Connect. Connect, however, was the only program where children continued to improve after the intervention. Overall, the results indicate that the 4 programs were equally effective in a clinical setting, despite differences in their theoretical origin.     

Parfit on fission

Derek Parfit famously defends a number of surprising views about “fission.” One is that, in such a scenario, it is indeterminate whether I have survived or not. Another is that the fission case shows that it does not matter, in itself, whether I survive or not. Most critics of the first view contend that fission makes me cease to exist. Most opponents of the second view contend that fission does not preserve everything that matters in ordinary survival. In this paper I shall provide a critique that does not rely on either of these contentions. There are other, interrelated reasons to reject Parfit’s defense of the two theses. In particular, the availability of the following view creates trouble for Parfit: I determinately survive fission, but it is indeterminate which fission product I am.     

How love and sex can influence recognition of faces and words: A processing model account

A link between romantic love and face recognition and sexual desire and verbal recognition is suggested. When in love, people typically focus on a long‐term perspective which enhances global perception, whereas when experiencing sexual encounters they focus on the present which enhances a perception of details. Because people automatically activate these processing styles when in love or sex, subtle reminders of love versus sex should suffice to change ways of perception. Global processing should further enhance face recognition, whereas local processing should enhance recognition of verbal information. In two studies participants were primed with concepts and thoughts of love versus sex. Compared to control groups, recognition of verbal material was enhanced after sex priming, whereas face recognition was enhanced after love priming. In Experiment 2 it was demonstrated that differences in global versus local perception mediated these effects. However, there was no indication for mood as a mediator.
