Understanding and Essence

Modal epistemology has been dominated by a focus on establishing an account either of how we have modal knowledge or how we have justified beliefs about modality. One component of this focus has been that necessity and possibility are basic access points for modal reasoning. For example, knowing that P is necessary plays a role in deducing that P is essential, and knowing that both P and ¬P are possible plays a role in knowing that P is accidental. Chalmers (2002) and Williamson (2007) provide two good examples of contrasting views in modal epistemology that focus on providing an account of modal knowledge where necessity and possibility are basic access points for modal knowledge, and Yablo (1993) provides a good account of how we have justified beliefs about modality. In contrast to this tradition I argue for and outline a modal epistemology based on objectual understanding and essence, rather than knowledge or justification and necessity and possibility. The account employs a non-modal conception of essence and takes objectual understanding of essence, rather than knowledge of essence to be basic in modal reasoning. I begin by articulating Kvanvig’s (2003) account of objectual understanding, on which objectual understanding of Φ is not equivalent to propositional knowledge of Φ. I then argue that an epistemology of essence that uses property variation-in-imagination is better construed as a model that delivers objectual understanding of essence rather than knowledge of essence. I argue that this is so, since the latter and not the former runs into a version of the Meno paradox. I show how this account can be applied to two issues in modal epistemology: the Benacerraf problem for modality, and the architecture of modal knowledge.     

Preventive interventions among children exposed to trauma of armed conflict: a literature review

Increasing research is available on the preconditions for child mental health and optimal development in traumatic conditions, whereas less is known how to translate the findings into effective interventions to help traumatized children. This literature review analyses the effectiveness of psychosocial preventive interventions and treatments and their theoretical bases among children traumatized in the context of armed conflicts (war, military violence, terrorism and refugee). The first aim is to evaluate the effectiveness of preventive interventions in preventing emotional distress and impairment and promoting optimal emotional‐cognitive and social development. The second task is to analyze the nature of the underlying mechanisms for the success of preventive interventions, and the theoretical premises of the choice of intervention techniques, procedures and tools. We found 16 relevant published studies, but an examination of them revealed that only four of them had experimental designs strong enough that they could be included in the meta‐analysis. While the subjective reports of the researchers suggested that systematic preventive interventions were effective in decreasing PTSD and depressive symptoms among children traumatized due to armed conflict, the more objective results of the meta‐analysis and the weaknesses in designs uncovered during the meta‐analysis undermine such a conclusion. Additionally, a majority of the reported preventive interventions focused only on children's biased cognitive processes and negative emotions, while only a few aimed at influencing multiple domains of child development and improving developmental functioning on emotional, social and psychophysiological levels. It is concluded that substantial additional work needs to be done in developing effective preventive interventions and treatments for children traumatized by exposure to war and violence. Aggr.

Maternal experience of their infants’ crying in the context of war trauma: Determinants and consequences

We examined, first, how prenatal maternal mental health and war trauma predicted mothers’ experience of their infant crying, indicated by emotions, cognitions, and behavior; and second, how these experiences influenced the mother–infant interaction and infant development. Participants were 511 Palestinian mothers from the Gaza Strip, reporting their war trauma, symptoms of posttraumatic stress disorder (PTSD), depression, and perceived stress during pregnancy (Time 1). They reported experiences of infant crying at 4 months (Time 2), and the mother–infant interaction and infant sensorimotor and language development at 12 months of infants’ age (Time 3). Results revealed that maternal mental health problems, but not war trauma, were important to experiences of infant crying. A high level of PTSD symptoms predicted negative emotions evoked by infant crying, and high depressive symptoms predicted low active and positive responses to crying. Unexpectedly, high prenatal perceived stress predicted high active and positive responsiveness. Concerning the consequences, mothers’ sensitive interpretation of infant crying predicted optimal infant sensorimotor development, and mothers’ active and positive responses predicted high emotional availability in mother–infant interaction. Crying is the first communication tool for infants, and mothers’ sensitive responses to crying contribute to infant well-being. Therefore, reinforcing mother's optimal responses is important when helping war-affected dyads.     

Beyond Protection Motivation: An Integrative Theory of Health Appeals

We develop an integrated theory of health communication by combining protection motivation theory (PMT; Rogers, 1983) with the stages of change described in the transtheoretical model (Prochaska & DClemente, 1982). Our study challenges the assumption implicit in PMT that perceptions of vulnerability, severity, response efficacy, and self-efficacy are equally weighted across individuals. Rather, we propose that people at different stages of readiness to change are differentially affected by levels of these predictor variables. Results from our experiment confirm that vulnerability, severity, and efficacy (response and self) are the main motivators to change behavior during the precontemplation, contemplation, and action stages, respectively. Furthermore, we explore how specific categories of beliefs identified by the transtheoretical model are associated with perceptions of vulnerability, severity, response efficacy, and self-efficacy.     

The Relationship Between Religious Service Attendance and Coronary Heart Disease and Related Risk Factors in Saskatchewan, Canada

Research suggests that attending religious services could provide small yet important protective benefits against coronary heart disease (CHD) and CHD risk factors (e.g., diabetes, hypertension). The extent to which these benefits apply to Canada deserves study because approximately one-third of adult Canadians attend religious services at least monthly. Therefore, the objective of this study is to examine the association between frequency of religious service attendance and prevalence of (1) CHD, (2) diabetes, and (3) hypertension in Canada. We used the Saskatchewan sample (n = 5,442) of the Canadian Community Health Survey (CCHS-4.1) and built multivariable logistic regression models to evaluate associations between religious service attendance and self-reported CHD, diabetes, and hypertension. After controlling for demographic, socioeconomic and health behavior variables, the association between religious service attendance and prevalence of CHD was not significant (OR = 0.82; 95 % CI 0.61–1.11). However, persons who attended religious services more than once a week exhibited lower prevalence odds of diabetes (OR = 0.60; 95 % CI 0.45–0.80) and hypertension (OR = 0.82; 95 % CI 0.68–0.99) compared to persons who attended less than once a year. The findings of this study are the first to suggest religious service attendance may be associated with a lower prevalence of CHD risk factors in Canada.     

On Getting Best of Both the Worlds

As continuing globalization brings psychological insights from varied backgrounds closer, the prospect for developing a richer psychology based on complementary insights and techniques opens up. Against this background, Prof. Rao’s paper correctly points out that time is now right for the convergence of traditional Indian Psychology (IP) and Positive Psychology (PP). What brings them together is their common aim to pursue the highest possible level of happiness. As pointed out by the author, the deeper philosophical foundations of Indian psychology (IP), and the expanding empirical studies of Positive Psychology (PP), are the strongest instances of their complementarity. Mutually enriching exchange between these fields can take place only on grounds of compatible principles. If this is correct, then a close examination of the basic ontological premises, epistemic principles, and convergent values is needed to ensure success in collaboration. At the same time it is important to recognize the points of conflict and possible fault lines so we could steer clear of them.     

When multiple identities compete: The role of centrality in self‐brand connections

The current research provides a framework for understanding how centrality impacts people's choice of brands and related brand connectedness. Motivated by the need to validate their self‐image, individuals use brands to express and confirm their identities. The authors hypothesize that greater centrality of the identity to the self strengthens the connectedness an individual has for brands with value‐expressive properties. Three studies using experimental designs examined whether people whose identity is central to their self‐conception leads to stronger self‐brand connectedness than peripheral identities. In study 1, the results showed that people whose shopping identity was central (versus peripheral) to their self‐concept led to stronger self‐brand connections. Study 2 replicated the findings of study 1 employing brand symbolism as a moderator. Brands high in symbolic properties led to stronger brand connections for an individual's central identities compared with their peripheral identities. Study 3 replicated the influence of centrality on brand choice and self‐brand connections by generalizing this effect to reference group identities. Collectively, the studies provide evidence that individuals integrate brand associations into their self‐concept on the basis of both the centrality of the identity and the level of symbolism the brands holds for an identity.
