Aristotle's Four Causes of Action

Aristotle's typical procedure is to identify four causes of natural changes. Intentional action, a natural change, has standardly been treated as an exception: most think that Aristotle has the standard causalist account, according to which an intentional action is a bodily movement efficiently caused by an attitude of the appropriate sort. I show that action is not an exception to Aristotle's typical procedure: he has the resources to specify four causes of action, and thus to articulate a powerful theory of action unlike any other on offer.     

Cognitive behavioral therapy for suicide prevention (CBT‐SP): Implications for meeting standard of care expectations with suicidal patients

Accumulating evidence supports the efficacy of cognitive behavioral therapy for suicide prevention (CBT‐SP) as an empirically supported treatment approach for suicidal patients. In light of these findings, several procedures pulled from CBT‐SP have been recommended for standard care with suicidal patients. The present article provides an overview of the procedures used in CBT‐SP and discusses how these procedures meet, or even exceed, standard of care expectations for outpatient mental healthcare clinicians. Finally, the relevance of clinician fidelity to the CBT‐SP model when evaluating standard of care expectations is discussed.     

Smoking in movies, implicit associations of smoking with the self, and intentions to smoke

We examined whether identifying with a film character who smokes increases implicit associations of the self with smoking. Undergraduate men were randomly assigned to view film clips in which the male protagonist either smoked or did not smoke. We measured subsequent levels of self-smoking associations using a reaction time task, as well as self-reported beliefs about smoking and smokers. Greater identification with the smoking protagonist predicted stronger implicit associations between the self and smoking (for both smokers and nonsmokers) and increased intention to smoke (among the smokers). Stronger implicit self-smoking associations uniquely predicted increases in smokers' intentions to smoke, over and above the effects of explicit beliefs about smoking. The results provide evidence that exposure to smoking in movies is causally related to changes in smoking-related thoughts, that identification with protagonists is an important feature of narrative influence, and that implicit measures may be useful in predicting deliberative behavior.     

The generation effect: A meta-analytic review

The generation effect refers to the finding that subjects who generate information (e.g., produce synonyms) remember the information better than they do material that they simply read. Meta-analytic techniques were used to summarize 445 effect sizes over 86 studies, thereby assessing the magnitude and 11 potential moderators of the generation effect. The size of the generation effect across the 86 studies was .40--a benefit of almost half a standard deviation of generation over reading. The variability of the effect size due to moderator type was substantial, and we attempted to use this information to clarify several theories that have been proposed to explain the generation effect.     

Displaywide visual features associated with a search display’s appearance can mediate attentional capture

Whether or not the capture of visual attention is driven solely by the salience of an attention-capturing stimulus or mediated by top-down control has been a point of contention since Folk, Remington, and Johnston (1992) introduced their contingent involuntary orienting hypothesis, which states that the capture of attention by a salient stimulus depends on its relevance to a feature distinguishing the target from nontargets. Gibson and Kelsey (1998) extended Folk et al.’s (1992) hypothesis by demonstrating that features associated with the appearance of the target display also mediate capture. Although similar to Folk et al. (1992), Gibson and Kelsey’s displaywide contingent orienting hypothesis makes it difficult to demonstrate stimulus-driven capture, because an observer must always use some perceptible feature as a signal of the target display’s appearance; hence, such features could always be mediating capture. The present article reviews and applies the logic of Gibson and Kelsey’s and Folk et al.’s (1992) hypotheses to experiments from the attentional capture literature, and assesses whether previously reported capture effects were mediated by top-down attentional control. It concludes that these capture effects were not stimulus-driven.     

A preliminary examination of the intergenerational continuity of maternal psychopathic features

The study provided a preliminary test of the intergenerational continuity of maternal psychopathic features in a non-referred elementary aged sample of children. Consistent with dominant etiological models and recent behavioral genetics research, a direct association was expected between maternal and child affective features of psychopathy (i.e., callous-unemotional or CU traits). Potential mediators representative of alternative transmission mechanisms were assessed including parenting dysfunction, parental hostility/interpersonal insensitivity, and child impulsivity. Behavioral features of psychopathy were also assessed and were predicted to bear weaker and more indirect parent-child associations. A mixed sex sample of 83 children accompanied by a biological mother were administered a multi-informant rating-scale battery including separate parent (i.e., Levenson Self-Report Psychopathy Scale) and child (i.e., Antisocial Process Screening Device) measures of psychopathy. Consistent with prediction, a significant association was documented between maternal and child CU traits (r=.22). Additionally, a slightly weaker association and statistical trend (r=.21) was observed in the relation between maternal and child interpersonal features of the psychopathy construct. Contrary to prediction, all documented associations were fully mediated by parental hostility and parenting dysfunction. Given the preliminary nature of study findings, implications for developmental modeling and future intergenerational continuity research are discussed.     

The Fisher-Pitman permutation test when testing for differences in mean and variance

The Fisher-Pitman permutation test can detect any type of difference between two samples: hence, a significant Fisher-Pitman permutation test does not necessarily provide evidence for a difference in means. It is possible, however, to test separately for differences in means and variances. Here, we present a recently proposed two-stage procedure to decide whether there are differences in means or variances that can be applied when samples may come from nonnormal distributions with possibly unequal variances.     

Randomness and inductions from streaks: “Gambler’s fallacy” versus ”hot hand“

Sometimes people believe that a run of similar independent events will be broken (belief in thegambler’s fallacy) but, other times, that such a run will continue (belief in the hot hand). Both of these opposite inductions have been explained as being due to belief in a law of small numbers. We argue that one factor that distinguishes these phenomena is people’s beliefs about the randomness of the underlying process generating the events. We gave participants information about a streak of events but varied the scenarios in such a way that the mechanism generating the events should vary in how random the participants would judge it to be. A manipulation check confirmed our assumptions about the scenarios. We found that with less random scenarios, the participants were more likely to continue a streak.     

What makes a girl (or a boy) popular (or unpopular)? African American children's perceptions and developmental differences

Open-ended questions were used to obtain narrative accounts of what makes a girl (or a boy) popular (or unpopular) at school. The participants were 489 African American students in Grades 1, 4, and 7 recruited from high-risk inner-city neighborhoods. Appearance and self-presentation were mentioned the most in Grades 4 and 7. Prosocial characteristics were especially relevant for popularity in Grade 1, as were studentship in Grade 4 and peer affiliations in Grade 7. Deviant behaviors were nominated for popularity more frequently in Grade 7 than in the younger grades and more for boys' popularity than for girls'. The mean deviance scores were negative in all grade levels, suggesting a normative peer culture. Male groups in Grade 7 showed significant homophily in reports of deviant behaviors.     

Treatment choice for PTSD

The impetus for seeking help for assault-related difficulties often rests upon the victims themselves. Yet, we know very little about what factors influence a woman's decision to seek a particular kind of help after an assault. To learn more about these factors, data from 273 women with varying degrees of trauma history and subsequent PTSD symptoms were collected. All participants read a standard, "if this happened to you, what would you do" scenario describing a traumatic event and subsequent trauma-related psychiatric symptoms. Participants were given the same trauma scenario (i.e., sexual assault) and three treatment options to choose from: sertraline (SER), prolonged exposure (PE), or no treatment. Ratings of treatment credibility, personal reactions to treatment options, and treatment choice were examined. Women were more likely to choose PE than SER for the treatment of chronic PTSD. Perceived credibility of the treatment and personal reactions coincided with women's choices. By better understanding who would choose which treatments for PTSD and why, we will improve our ability to tailor how we approach discussing treatment options with these women.
