Relationship of Prosody Perception to Personality and Aggression

One-hundred-fifteen participants (73 female, 42 male) were evaluated for prosody, or vocal emotion, perception, personality factors, relational aggression and physical aggression. The male participants reported higher levels of physical aggression, and the female participants reported greater Neuroticism, consistent with other data. For the male participants, better perception of prosody was related to both greater Extraversion and greater Conscientiousness, all involved in interpersonal functioning. These relationships were not found in the female participants, but there was a relationship between perception of prosody and relational aggression. Women who were better at perceiving the emotional status of others based on vocal cues were less relationally aggressive. Perhaps greater relational aggression reflects a poor adaptation to diminished ability to perceive emotional status.     

Developing Culturally Responsive Evidence-Based Practice: A Game-Based Group Therapy Program for Child Sexual Abuse (CSA)

The American Psychological Association has called for the development and dissemination of evidence-based practices (EBPs) that are culturally responsive to ethnically and socioeconomically diverse groups. Delivering culturally responsive EBPs is essential for mental health practitioners working within racially, culturally, and ethnically diverse settings and across a variety of disorders. Child sexual abuse (CSA) affects people from diverse backgrounds and results in a myriad of difficulties impacting children and families. Therefore, effective treatment for CSA must take cultural factors into consideration. The authors describe the culturally congruent elements of a Game-Based Cognitive-Behavioral Group Therapy (GB-CBT) model for CSA, which was developed within a center serving predominantly urban, economically disadvantaged, African-American and Latino families. Lessons learned from families served through the GB-CBT program are incorporated and illustrate the ongoing and dynamic process of improving cultural competence in clinical practice. Cultural and socioeconomic considerations and obstacles to treatment are discussed along with strategies and recommendations for delivering EBPs for CSA in a culturally informed manner.     

What is Absolute Undecidability?†

It is often alleged that, unlike typical axioms of mathematics, the Continuum Hypothesis (CH) is indeterminate. This position is normally defended on the ground that the CH is undecidable in a way that typical axioms are not. Call this kind of undecidability “absolute undecidability”. In this paper, I seek to understand what absolute undecidability could be such that one might hope to establish that (a) CH is absolutely undecidable, (b) typical axioms are not absolutely undecidable, and (c) if a mathematical hypothesis is absolutely undecidable, then it is indeterminate. I shall argue that on no understanding of absolute undecidability could one hope to establish all of (a)–(c). However, I will identify one understanding of absolute undecidability on which one might hope to establish both (a) and (c) to the exclusion of (b). This suggests that a new style of mathematical antirealism deserves attention—one that does not depend on familiar epistemological or ontological concerns. The key idea behind this view is that typical mathematical hypotheses are indeterminate because they are relevantly similar to CH.     

Commitment to the GLBT community: an investment model analysis of its antecedents and consequences

The present research applied the investment model to the study of how gay, lesbian, bisexual, and transgender (GLBT) persons become committed to the broader community of sexual minorities. In addition, the present research examined the potential consequences associated with such commitment. In Study 1, satisfaction, investments, and alternatives each uniquely predicted an individual's commitment to the GLBT community. In Study 2, commitment to the GLBT community predicted higher levels of GLBT identification and stronger intentions to be involved in the community in the future. This research has important implications for understanding the factors that promote strong commitment to minority communities and how such commitment may play a vital role in facilitating social and political change for lower status groups.     

The cost of forfeiting causal inheritance

Jaegwon Kim’s causal inheritance principle says that the causal powers of a mental property instance are identical with the causal powers of its particular physical realizer. Sydney Shoemaker’s subset account of realization is at odds with Kim’s principle: it says that a mental property instance has fewer causal powers than Kim’s principle entails. In this paper, I argue that the subset account should be rejected because it has intolerable consequences for mental causation, consequences that are avoided by accepting causal inheritance. I develop my argument in part by drawing on one of the central debates that has arisen regarding the extended mind hypothesis defended by Andy Clark and David Chalmers.     

Teenage Drug and Alcohol Use: Comparing Individual and Contextual Effects

While both macro- and micro-level studies have identified important correlates of substance use, multi-level models may explain more than each level alone. Drawing on extant research and Akers' (1998 Akers , Ronald L. 1998 . Social Learning and Social Structure: A General Theory of Crime and Deviance . Boston : Northeastern University Press . [Google Scholar]) Social Structure-Social Learning model, we offer hypotheses about the relationship between contextual- and individual-level explanatory variables and substance use. The sample included 85,000 students in 202 school districts. Hierarchical linear modeling revealed low socioeconomic status, percent rural, and racial composition directly affected use of some substances net individuals' characteristics. Further, the effects of gender, age, and class were substantially mediated by differential association and school bonds, which significantly influenced alcohol, marijuana, ecstasy, and methamphetamine use.     

Rebel Without a (Conscious) Cause: Priming a Nonconscious Goal for Psychological Reactance

Psychological Reactance is typically studied using conscious manipulations and individual-difference measures. We hypothesized that, similar to other goals, a reactance motive can be primed nonconsciously. In this experiment, participants were given an explicit expectation that a pill would improve their performance on an accuracy task, or they were not given this expectation. Participants also received a reactance or neutral prime. On a subsequent accuracy task, participants given both the reactance prime and the explicit accuracy expectation committed the most errors. The findings suggest that reactance can be nonconsciously primed, generating behavioral effects. Evidence supporting the goal-priming interpretation is also presented.     

Decision criteria do not shift: Commentary on Mueller and Weidemann (2008)

The effects of base rates and payoffs on the shapes of rating receiver operating characteristic curves are inconsistent with the basic assumptions of signal detection theory (SDT), in particular the notion of a shifting decision criterion. Mueller and Weidemann (2008) propose that these unexpected phenomena are not due to problems with the decision- criterion construct but are instead due to two compounded effects: instability of the decision criterion across trials, and even greater instability in the flanking criteria that determine which confidence rating will be reported. There are several problems with the authors’ decision-noise hypothesis. First, even if their hypothesis about decision noise were taken for granted, the key feature of the ratings data that rejects the SDT model would remain a mystery. Second, the same violations of SDT that are exhibited in the ratings paradigm are also exhibited in the yes-no detection task when response time is substituted for confidence as a basis for analysis. Finally, the decision-noise hypothesis predicts that sensitivity will increase when one source of this variation-the response on a previous trial-is controlled for. This prediction was consistently violated in both the yes-no and ratings conditions of Mueller and Weidemann’s experiment. In an Addendum, we respond to Weidemann and Mueller’s (2008) reply to this Comment.
