Parent Programs for Reducing Adolescent’s Antisocial Behavior and Substance Use: A Randomized Controlled Trial

Two theoretically based parent training programs, delivered in real-world settings by the social services, were examined in this randomized controlled trial for effectiveness in reducing adolescents’ antisocial behavior and substance use. Two hundred and thirty-seven (237) adolescents in ages between 12 and 18 and their parents were assigned to one of two programs or to a wait-list control condition. The programs were the nine weekly group sessions program Comet 12–18 (Swedish Parent Management Training Program) and the six weekly ParentSteps (Swedish shortened version by Strengthening Families Program 10–14). Outcome measures were antisocial behavior, substance use, and delinquency, and psychosocial dysfunction. Data based on adolescents’ and parents’ ratings of the adolescents’ problem behavior at baseline and 6 months later were analyzed with repeated measures ANVOA, Logistic regression, and Kruskal–Wallis H test. The results showed that parents’ ratings of adolescents’ antisocial behaviors decreased significantly over time, but no time by group effect emerged. No program effects were found in the adolescents’ self-reported antisocial behavior, delinquency, or psychosocial functioning. A threefold risk of illicit drug use was found in both intervention groups. The results suggest that neither Comet nor ParentSteps had beneficial effects on adolescent’s antisocial or delinquent behavior, or on alcohol use. The only significant group difference found was a threefold risk of drug use in the intervention adolescents at follow-up, but for several reasons this finding should be interpreted with caution.

Counterfactual and prefactual conditionals.

We consider reasoning about prefactual possibilities in the future, for example, "if I were to win the lottery next year I would buy a yacht" and counterfactual possibilities, for example, "if I had won the lottery last year, I would have bought a yacht." People may reason about indicative conditionals, for example, "if I won the lottery I bought a yacht" by keeping in mind a few true possibilities, for example, "I won the lottery and I bought a yacht." They understand counterfactuals by keeping in mind two possibilities, the conjecture, "I won the lottery and I bought a yacht" and the presupposed facts, "I did not win the lottery and I did not buy a yacht." We report the results of three experiments on prefactuals that examine what people judge them to imply, the possibilities they judge to be consistent with them, and the inferences they judge to follow from them. The results show that reasoners keep a single possibility in mind to understand a prefactual.     

Embodied emotion concepts: How generating words about pride and disappointment influences posture

Embodiment theories predict that activating conceptual knowledge about emotions can be accompanied by re‐experiencing bodily states, since simulations of sensory, motor, and introspective experiences form the foundation of conceptual representations of emotion. In the present study, we examine whether the activation of the specific emotion concepts of pride and disappointment are embodied in the sense that they are accompanied by changes in posture. Participants generated words associated with pride and disappointment while posture height was measured. Results show that during the generation of disappointment words participants decreased their posture height more than when participants generated pride words. This finding suggests that the activation of conceptual knowledge about disappointment can lead to a spontaneous expression of the associated body posture. In contrast to posture changes along the vertical axis, movement along the horizontal axis was not influenced by concept activation. In addition to bodily simulation the data also indicated introspective simulation, since feelings of disappointment increased after generating disappointment words. The current study provides the first evidence for the claim that the activation of conceptual knowledge about emotion can instantiate spontaneous simulations at a behavioral level.

How to Precisify Quantifiers

I here argue that Ted Sider's indeterminacy argument against vagueness in quantifiers fails. Sider claims that vagueness entails precisifications, but holds that precisifications of quantifiers cannot be coherently described: they will either deliver the wrong logical form to quantified sentences, or involve a presupposition that contradicts the claim that the quantifier is vague. Assuming (as does Sider) that the “connectedness” of objects can be precisely defined, I present a counter-example to Sider's contention, consisting of a partial, implicit definition of the existential quantifier that in effect sets a given degree of connectedness among the putative parts of an object as a condition upon there being something (in the sense in question) with those parts. I then argue that such an implicit definition, taken together with an “auxiliary logic” (e.g., introduction and elimination rules), proves to function as a precisification in just the same way as paradigmatic precisifications of, e.g., “red”. I also argue that with a quantifier that is stipulated as maximally tolerant as to what mereological sums there are, precisifications can be given in the form of truth-conditions of quantified sentences, rather than by implicit definition.     

When your heart is in your mouth: the effect of second language use on negative emotions

Research on bilingualism and emotions has shown stronger emotional responses in the native language (L1) compared to a foreign language. We investigated the potential of purposeful second language (L2) use as a means of decreasing the experience of psychological distress. Native Swedish speakers read and answered questions about negative and neutral texts in their L1 (Swedish) and their L2 (English) and were asked to rate their level of distress before or after the questions. The texts and associated questions were either written in the same (within-language), or different languages (cross-language). We found that within-language trials when the text was written in participants’ native language (Swedish–Swedish) resulted in an increase of distress, whilst cross-language trials (Swedish–English) resulted in a decrease of distress. This implies that purposeful second language use can diminish levels of distress experienced following a negative event encoded in one's first language.     

Testing a Moderated Mediation Model of Objectification Theory among Black Women in the United States: The Role of Protective Factors

Recent studies find that Black women experience rates of eating pathology and body dissatisfaction comparable to those of White women. Abundant research suggests that objectification theory could help explain the development and maintenance of eating disorder (ED) symptoms among diverse women. However, research on the applicability of objectification theory to ED symptoms in Black women is equivocal. Specifically, some have suggested that body surveillance might operate differently for Black women. Thus, the current study examined ethnic-racial identity (ERI) commitment and body appreciation as moderators of the mediated associations among body surveillance, body shame, and ED symptoms. Black women (n?=?175) in the United States completed measures of body image, ERI commitment, and ED symptoms. Consistent with objectification theory, body shame mediated the association between body surveillance and ED symptoms. Contrary to our hypothesis, ERI commitment did not moderate the link between body surveillance and body shame. However, body appreciation was a significant moderator, such that the strength of the relation between body surveillance and ED symptoms via body shame was weakened at high levels of body appreciation. Future work should consider interventions that foster body appreciation in Black women.

     

Effects of normal aging and Alzheimer's disease on emotional memory

Recall is typically better for emotional than for neutral stimuli. This enhancement is believed to rely on limbic regions. Memory is also better for neutral stimuli embedded in an emotional context. The neural substrate supporting this effect has not been thoroughly investigated but may include frontal lobe, as well as limbic circuits. Alzheimer's disease (AD) results in atrophy of limbic structures, whereas normal aging relatively spares limbic regions but affects prefrontal areas. The authors hypothesized that AD would reduce all enhancement effects, whereas aging would disproportionately affect enhancement based on emotional context. The results confirmed the authors' hypotheses: Young and older adults, but not AD patients, showed better memory for emotional versus neutral pictures and words. Older adults and AD patients showed no benefit from emotional context, whereas young adults remembered more items embedded in an emotional versus neutral context.
