Is It Possible to Become Happier? (And If So,How?)

Although some theory suggests that it is impossible to increase one's subjective well-being (SWB), our 'sustainable happiness model' ( Lyubomirsky, Sheldon, & Schkade, 2005 ) specifies conditions under which this may be accomplished. To illustrate the three classes of predictor in the model, we first review research on the demographic/circumstantial, temperament/personality, and intentional/experiential correlates of SWB. We then introduce the sustainable happiness model, which suggests that changing one's goals and activities in life is the best route to sustainable new SWB. However, the goals and activities must be of certain positive types, must fit one's personality and needs, must be practiced diligently and successfully, must be varied in their timing and enactment, and must provide a continued stream of fresh positive experiences. Research supporting the model is reviewed, including new research suggesting that happiness intervention effects are not just placebo effects.     

A critical review of ERP and fMRI evidence on L2 syntactic processing

The current review focuses on recent event-related brain potential (ERPs) and functional magnetic resonance imaging (fMRI) in L2 syntactic processing data. To this end, critical factors influencing both the dynamics of neural mechanisms (ERPs) and critical functional brain correlates (fMRI) are discussed. These entail the critical period hypothesis, levels of proficiency, cross-linguistic syntactic similarities and dissimilarities as well as brain bases that may or may not be shared during syntactic processing in a first (L1) and a second (L2) language. The data to date reveal that (i) the critical period hypothesis plays less of a significant role than initially discussed, (ii) L2 proficiency is a driving factor influencing peak and extent of activation in brain correlates and in neurophysiological mechanisms as a function of learning, and (iii) language transfer effects (i.e., positive transfer effects when L1 and L2 are structurally similar or negative transfer effects when L1 and L2 are structurally dissimilar) primarily from the L1 to the L2 and potentially vice versa need to be critically considered in future research.     

Car use of young adults: The role of travel socialization

This study evaluates how different aspects of travel socialization during childhood and adolescence contribute to the explanation of travel mode choice in young adulthood. In an online survey with 2612 students who had access to a car three different socialization aspects were measured retrospectively: communication with parents about the environmental impact of travel mode choice at the participants’ age of 15, the symbolic-affective importance of driving and acquisition of a driver’s license at the age of 18, and finally multi-mobility in the peer group at the age of 18. It was expected that socialization constructs would have a direct effect on social and personal norm as wells as on car use habit and an indirect effect on car use, mediated by norms, habit and intention. Structural equation modelling showed a significant impact of all socialization constructs on either norms or car use habit or both. Moreover, the postulated mediator effect could be confirmed. The paper encourages widening the perspective of transport studies by aspects of socialization, which have been neglected in former research on adults mobility behaviour.     

Keep ‘hoping’ for rationality: a solution to the backward induction paradox

We formalise a notion of dynamic rationality in terms of a logic of conditional beliefs on (doxastic) plausibility models. Similarly to other epistemic statements (e.g. negations of Moore sentences and of Muddy Children announcements), dynamic rationality changes its meaning after every act of learning, and it may become true after players learn it is false. Applying this to extensive games, we “simulate” the play of a game as a succession of dynamic updates of the original plausibility model: the epistemic situation when a given node is reached can be thought of as the result of a joint act of learning (via public announcements) that the node is reached. We then use the notion of “stable belief”, i.e. belief that is preserved during the play of the game, in order to give an epistemic condition for backward induction: rationality and common knowledge of stable belief in rationality. This condition is weaker than Aumann’s and compatible with the implicit assumptions (the “epistemic openness of the future”) underlying Stalnaker’s criticism of Aumann’s proof. The “dynamic” nature of our concept of rationality explains why our condition avoids the apparent circularity of the “backward induction paradox”: it is consistent to (continue to) believe in a player’s rationality after updating with his irrationality.     

Character Strengths and Job Satisfaction: Differential Relationships Across Occupational Groups and Adulthood

Character strengths are a central construct within positive psychology, and their importance for the workplace was supported recently. Little is known, however, which strengths matter the most at the workplace. The aim of the present investigation was thus to assess the relationship between the level of the 24 character strengths with overall job satisfaction in a general working population (N = 12,499) as well as in eight occupational subgroups (nurses, physicians, supervisors, office workers, clinical psychologists, social workers/educators, economists, and secondary-school teachers) and in six age groups (from 18 to 61+ years) and to compare the overall level of character strengths across the eight occupational subgroups. Results showed that, similar to life satisfaction, zest, hope, curiosity, love, and gratitude, and emotional strengths in general, related most strongly to overall job satisfaction. However, the relationships of the strengths with job satisfaction differed depending on the facet of job satisfaction, the occupational subgroup, and the age group under study. Knowing which individual strengths as well as strengths factors are more important for specific working populations can help to develop and apply more effective strength-based interventions in the workplace, thus improving positive and reducing negative work-related outcomes.

     

The dynamic turn in quantum logic

In this paper we show how ideas coming from two areas of research in logic can reinforce each other. The first such line of inquiry concerns the ??dynamic turn?? in logic and especially the formalisms inspired by Propositional Dynamic Logic (PDL); while the second line concerns research into the logical foundations of Quantum Physics, and in particular the area known as Operational Quantum Logic, as developed by Jauch and Piron (Helve Phys Acta 42:842?C848, 1969), Piron (Foundations of Quantum Physics, 1976). By bringing these areas together we explain the basic ingredients of Dynamic Quantum Logic, a new direction of research in the logical foundations of physics.     

Primary Care Physicians’ Awareness, Experience and Opinions of Direct-to-Consumer Genetic Testing

The purpose of this study was to assess primary care physicians’ awareness, experience, opinions and preparedness to answer patients’ questions regarding direct-to-consumer (DTC) genetic testing. An anonymous survey was mailed to 2,402 family and internal medicine providers in North Carolina. Of the 382 respondents, 38.7% (n = 148) were aware of and 15% (n = 59) felt prepared to answer questions about DTC genetic tests. Respondents aged 50 or older were more likely to be aware of DTC genetic testing than those less than 40 years old (OR = 2.42). Male providers were more likely to feel prepared to answer questions than female providers (OR = 2.65). Among respondents who reportedly were aware, family practitioners were more likely than internists (OR = 3.30) to think DTC testing was clinically useful, and 18.9% had patients ask questions or bring in test results. The small percent of physicians who were aware of DTC genetic testing or felt prepared to answer questions about it suggests that education of providers will be necessary if testing becomes more widespread.     

Involving Parents in Indicated Early Intervention for Childhood PTSD Following Accidental Injury

Accidental injuries represent the most common type of traumatic event to which a youth is likely to be exposed. While the majority of youth who experience an accidental injury will recover spontaneously, a significant proportion will go on to develop Post-Traumatic Stress Disorder (PTSD). And yet, there is little published treatment outcome research in this area. This review focuses on two key issues within the child PTSD literature—namely the role of parents in treatment and the timing of intervention. The issue of parental involvement in the treatment of child PTSD is a question that is increasingly being recognized as important. In addition, the need to find a balance between providing early intervention to at risk youth while avoiding providing treatment to those youth who will recover spontaneously has yet to be addressed. This paper outlines the rationale for and the development of a trauma-focused CBT protocol with separate parent and child programs, for use with children and adolescents experiencing PTSD following an accidental injury. The protocol is embedded within an indicated intervention framework, allowing for the early identification of youth at risk within a medical setting. Two case studies are presented in order to illustrate key issues raised in the review, implementation of the interventions, and the challenges involved.     

Neural substrates of individual differences in human fear learning: Evidence from concurrent fMRI, fear-potentiated startle, and US-expectancy data

To provide insight into individual differences in fear learning, we examined the emotional and cognitive expressions of discriminative fear conditioning in direct relation to its neural substrates. Contrary to previous behavioral-neural (fMRI) research on fear learning--in which the emotional expression of fear was generally indexed by skin conductance--we used fear-potentiated startle, a more reliable and specific index of fear. While we obtained concurrent fear-potentiated startle, neuroimaging (fMRI), and US-expectancy data, healthy participants underwent a fear-conditioning paradigm in which one of two conditioned stimuli (CS(+) but not CS(-)) was paired with a shock (unconditioned stimulus [US]). Fear learning was evident from the differential expressions of fear (CS(+) > CS(-)) at both the behavioral level (startle potentiation and US expectancy) and the neural level (in amygdala, anterior cingulate cortex, hippocampus, and insula). We examined individual differences in discriminative fear conditioning by classifying participants (as conditionable vs. unconditionable) according to whether they showed successful differential startle potentiation. This revealed that the individual differences in the emotional expression of discriminative fear learning (startle potentiation) were reflected in differential amygdala activation, regardless of the cognitive expression of fear learning (CS-US contingency or hippocampal activation). Our study provides the first evidence for the potential of examining startle potentiation in concurrent fMRI research on fear learning.     

Self-Construal and Cooperation: Is the Interdependent Self More Cooperative Than the Independent Self?

The present study examined whether a temporary activation of independent or interdependent self-construals by priming has an influence on cooperation in social dilemmas. It was expected that individuals primed with independence would be primarily concerned with their own outcomes, whereas individuals primed with interdependence would also be concerned with the outcomes of their interaction partner. The former should therefore exhibit lower levels of cooperation. Additionally, the influence of social value orientation on cooperation was measured. Participants played 32 rounds of a give-some dilemma with an alleged interaction partner. As predicted, participants primed with independence exhibited lower levels of cooperation than participants primed with interdependence. Results are discussed in terms of their significance for research on self-construals and social dilemmas.
