MAXIMALITY,DUPLICATION, AND INTRINSIC VALUE

In this paper, I develop an argument for the thesis that ‘maximality is extrinsic’, on which a whole physical object is not a whole of its kind in virtue of its intrinsic properties. Theodore Sider has a number of arguments that depend on his own simple argument that maximality is extrinsic. However, Peter van Inwagen has an argument in defence of his Duplication Principle that, I will argue, can be extended to show that Sider's simple argument fails. However, van Inwagen's argument fails against a more complex, sophisticated argument that maximality is extrinsic. I use van Inwagen's own commitments to various forms of causation and metaphysical possibility to argue that maximality is indeed extrinsic, although not for the mundane reasons that Sider suggests. I then argue that moral properties are extrinsic properties. Two physically identical things can have different moral properties in a physical world. This argument is a counterexample to a classical ethical supervenience idea (often attributed to G.E. Moore) that if there is identity of physical properties in a physical world, then there is identity in moral properties as well. I argue moral value is ‘border sensitive’ and extrinsic for Kantians, utilitarians, and Aristotelians.     

Positive psychology and war: an oxymoron

The author was deeply disturbed by the January 2011 issue of the American Psychologist, which engendered a series of emotions in the author: first dismay, then anger, and finally a sense of shame about the current state of the profession. This was ostensibly an exposition of "positive psychology" principles and how they are to be applied in a colossal experiment designed to support our military in their fight against the ideology of jihadist Islam. The author found it hard to see what was positive in the presentation. Not one of the authors in this special issue discussed applying positive psychology principles to the reduction of conflict between nations, to the prevention of war, or to the promotion of peace. How about a positive psychology that questions the wisdom of leaders who tell us that the use of force is unavoidable, and seeks instead to help them find alternative, peaceful solutions? A true positive psychology should be primarily addressed to eradicating the disease of war, not to supporting those who fight it.     

Interteaching: the impact of lectures on student performance

Several studies suggest that interteaching improves student learning more than traditional lectures, but few have examined which components of interteaching contribute to its efficacy. We examined whether the lecture component of interteaching affected students' exam grades and cumulative point totals in a research methods course. Although students who received lectures had consistently higher exam scores than students who did not, the differences were statistically significant on only 2 of 5 exams. Students who received lectures, however, earned significantly more points during the semester.     

Getting it right generally,but not precisely: learning the relation between multiple inputs and outputs

In real-world situations, people are often faced with the complex task of deciding which of many potential variables are affecting their own or others’ behavior, as well as noting which specific aspects of behavior are being affected. Although it is common for professionals who encounter such conditions to claim that they acquire accurate and specific knowledge from their experience, it is unclear that such confidence is justified. Using a managerial task, we examined participants’ ability to learn how various interventions affect various aspects of their employees’ performance. The results of three experiments reveal that although participants appear to avoid prescribing an intervention that has a positive effect on a primary performance measure and a negative side effect on a secondary measure, when asked directly about the impact of the intervention, they respond by reducing their judgments of its positive impact. This was true regardless of whether participants indicated clear knowledge of its negative side effect (Experiment 3) or did not (Experiments 1 and 2). Thus, participants appear to be automatically integrating across the effects on different outcome measures.     

Common factors of change in couple therapy

Though it is clear from meta-analytic research that couple therapy works well, it is less clear how couple therapy works. Efforts to attribute change to the unique ingredients of a particular model have consistently turned up short, leading many researchers to suggest that change is due to common factors that run through different treatment approaches and settings. The purpose of this article is to provide an empirically based case for several common factors in couple therapy, and discuss clinical, training, and research implications for a common factors couple therapy paradigm. Critical distinctions between model-driven and common factors paradigms are also discussed, and a moderate common factors approach is proposed as a more useful alternative to an extreme common factors approach.     

Caught in a bad romance: perfectionism, conflict, and depression in romantic relationships

According to the social disconnection model, perfectionistic concerns (i.e., harsh self-scrutiny, extreme concern over mistakes and others' evaluations, and excessive reactions to perceived failures) confer vulnerability to depressive symptoms indirectly through interpersonal problems. This study tested the social disconnection model in 226 heterosexual romantic dyads using a mixed longitudinal and experience sampling design. Perfectionistic concerns were measured using three partner-specific self-report questionnaires. Conflict was measured as a dyadic variable, incorporating reports from both partners. Depressive symptoms were measured using a self-report questionnaire. Perfectionistic concerns and depressive symptoms were measured at Day 1 and Day 28. Aggregated dyadic conflict was measured with daily online questionnaires from Days 2 to 15. Data were analyzed using structural equation modeling. There were four primary findings: (a) Dyadic conflict mediated the link between perfectionistic concerns and depressive symptoms, even when controlling for baseline depressive symptoms; (b) depressive symptoms were both an antecedent and a consequence of dyadic conflict; (c) perfectionistic concerns incrementally predicted dyadic conflict and depressive symptoms beyond neuroticism (i.e., a tendency to experience negative emotions) and other-oriented perfectionism (i.e., rigidly demanding perfection from one's partner); and (d) the relationships among variables did not differ based on gender. As the most rigorous test of the social disconnection model to date, this study provides strong support for this emerging model. Results also clarify the characterological and the interpersonal context within which depressive symptoms are likely to occur.     

Concurrent validity of an online version of the Timeline Followback assessment

The Timeline Followback (TLFB) interview has been used extensively in the assessment of alcohol and other substance use. While this methodology has been validated in multiple formats for multiple behaviors, to date no systematic comparisons have been conducted between the traditional interview format and online versions. The present research employed a randomized within-subjects design to compare interview versus online-based TLFB assessments of alcohol and marijuana use among 102 college students. Participants were randomly assigned to receive either the online version first or the in-person interview format first. Participants subsequently completed the second format within 3 days. While we expected few overall differences between formats, we hypothesized that differences might emerge to the extent that participants are more comfortable and willing to answer honestly in an online format, which provides a degree of anonymity. Results were consistent with expectations in suggesting relatively few differences between the online version and the in-person version. Participants did report feeling more comfortable in completing the online version. Moreover, greater discomfort during the in-person assessment was associated with reporting more past-month marijuana use on the online assessment, but reported discomfort did not moderate differences between formats in reported alcohol consumption.

Effects of symptom presentation order on perceived disease risk

People are quick to perceive meaningful patterns in the co-occurrence of events. We report two studies exploring the effects of streaks in symptom checklists on perceived personal disease risk. In the context of these studies, a streak is a sequence of consecutive items on a list that share the characteristic of being either general or specific. We identify a psychological mechanism underlying the effect of streaks in a list of symptoms and show that the effect of streaks on perceived risk varies with the length of the symptom list. Our findings reveal a tendency to infer meaning from streaks in medical and health decision making. Participants perceived a higher personal risk of having an illness when presented with a checklist in which common symptoms were grouped together than when presented with a checklist in which these same symptoms were separated by rare symptoms. This research demonstrates that something as arbitrary as the order in which symptoms are presented in a checklist can affect perceived risk of disease.
