Stress,healthiness and health behaviours: An exploration of the role of life events,daily hassles,cognitive appraisal and the coping process

In a study of 220 participants, the relationship between life events, daily hassles, cognitive appraisal and coping, stress and general healthiness was investigated utilizing a self report methodology. The different aspects of healthiness and health behaviour/lifestyle appear to be related to different appraisal and coping styles. The role of daily hassles and life events in the process also vary across different aspects of health, illness and health behaviours. In fact the number of life events experienced appear to contribute more to hardiness than to vulnerability. It is proposed that to understand the process an integrative model is required which allows for flexibility in analysis.     

Coping with neck and low back pain in the general population.

This study had 2 objectives: (a) to assess the psychometric properties of the Pain Management Inventory (PMI; G. K. Brown & P. M. Nicassio, 1987) with individuals in the general population with neck or low back pain, and (b) to assess the relationship between pain severity and coping. Data were taken from a mailed survey of a random sample of adults residing in Saskatchewan, Canada. Results validated the 2-factor structure of the PMI and provided evidence for the internal consistency of the coping subscales. Regression analyses revealed that passive coping was associated with being married, greater pain severity, depression, and poor health. Active coping was associated with female gender, higher education, less depression, good health, and frequent exercise. This study provides psychometric data to support the use of the PMI and information about factors associated with use of active and passive coping strategies in pain sufferers.     

NARROW HEDONISM

Narrow hedonism is defined and defended, as a view according to which pleasurable states are individuated as concrete and total experiential situations of a sentient being at a time. Typical of such situations is that, when we are in them, we are at a certain hedonic level. They feel in a certain way for the creature in them. On this understanding of narrow hedonism, which is the only one making good sense of the theory and which was probably also intended by classical hedonists such as Bentham and Edgeworth, standard objections to hedonism, based on the claim that different pleasures have nothing in common, can be set to one side as misplaced and irrelevant. It is also hard to see how this kind of hedonism can be refined, or revised, in the direction indicated by J.S. Mill, when he wants to distinguish “higher” pleasures from “lower” ones. On this understanding of hedonism, we must claim that, those who want to follow Mill will have to rely on non-hedonistic intuitions and thus desert the hedonist camp altogether.     

Priming as a way of understanding children’s mental representations of the social world

Priming is a well established tool for experimental examination of how mental representations drive thoughts, feelings, and behaviors that has been widely used in adult research. Priming is also a well established technique in cognitive development research. Social development research, however, has rarely used priming as a research method despite evidence that this technique is promising for helping researchers untangle causal connections between children’s mental representations and children’s social development outcomes. This paper discusses how priming methods may yield important insights into the role that children’s mental representations of the social world play in children’s social functioning. We begin by discussing the theoretical conceptualization underlying priming and priming methods. We next review evidence demonstrating the effectiveness of priming techniques in child development research. We conclude by suggesting ways in which priming can inform future research in social development using research examining attachment, social-information-processing, gender development, and mood and mental health as examples.     

The politics of time: Conservatives differentially reference the past and liberals differentially reference the future

Conservatives are thought to favor certainty and value tradition (suggesting a focus on the past), whereas liberals are thought to favor change (suggesting a focus on the future), even when it is associated with some degree of uncertainty. On this basis, two studies contrasted references to the past versus the future in language usage. Study 1 analyzed 600 texts from conservative and liberal websites. After adjusting for normative differences, a cross‐over interaction was obtained: Conservative posts referenced the past to a greater extent than the future and liberal posts referenced the future more than the past. A conceptually parallel cross‐over interaction was obtained in Study 2, which analyzed 145 State of the Union addresses. The temporal orientation of conservatives and liberals, then, appears qualitatively different.     

Executive function and psychosocial adjustment in healthy children and adolescents: A latent variable modelling investigation

The objective of this study was to establish latent executive function (EF) and psychosocial adjustment factor structure, to examine associations between EF and psychosocial adjustment, and to explore potential development differences in EF-psychosocial adjustment associations in healthy children and adolescents. Using data from the multisite National Institutes of Health (NIH) magnetic resonance imaging (MRI) Study of Normal Brain Development, the current investigation examined latent associations between theoretically and empirically derived EF factors and emotional and behavioral adjustment measures in a large, nationally representative sample of children and adolescents (7–18 years old; N = 352). Confirmatory factor analysis (CFA) was the primary method of data analysis. CFA results revealed that, in the whole sample, the proposed five-factor model (Working Memory, Shifting, Verbal Fluency, Externalizing, and Internalizing) provided a close fit to the data, χ²(66) = 114.48, p < .001; RMSEA = .046; NNFI = .973; CFI = .980. Significant negative associations were demonstrated between Externalizing and both Working Memory and Verbal Fluency (p < .01) factors. A series of increasingly restrictive tests led to the rejection of the hypothesis of invariance, thereby precluding formal statistical examination of age-related differences in latent EF-psychosocial adjustment associations. Findings indicate that childhood EF skills are best conceptualized as a constellation of interconnected yet distinguishable cognitive self-regulatory skills. Individual differences in certain domains of EF track meaningfully and in expected directions with emotional and behavioral adjustment indices. Externalizing behaviors, in particular, are associated with latent Working Memory and Verbal Fluency factors.     

Do gray wolves (<Emphasis Type="Italic">Canis lupus</Emphasis>) support pack mates during aggressive inter-pack interactions?

For group-living mammals, social coordination increases success in everything from hunting and foraging (Crofoot and Wrangham in Mind the Gap, Springer, Berlin, 2010; Bailey et al. in Behav Ecol Sociobiol 67:1–17, 2013) to agonism (Mosser and Packer in Anim Behav 78:359–370, 2009; Wilson et al. in Anim Behav 83:277–291, 2012; Cassidy et al. in Behav Ecol 26:1352–1360, 2015). Cooperation is found in many species and, due to its low costs, likely is a determining factor in the evolution of living in social groups (Smith in Anim Behav 92:291–304, 2014). Beyond cooperation, many mammals perform costly behaviors for the benefit of group mates (e.g., parental care, food sharing, grooming). Altruism is considered the most extreme case of cooperation where the altruist increases the fitness of the recipient while decreasing its own fitness (Bell in Selection: the mechanism of evolution. Oxford University Press, Oxford 2008). Gray wolf life history requires intra-pack familiarity, communication, and cooperation in order to succeed in hunting (MacNulty et al. in Behav Ecol doi: 10.1093/beheco/arr159 2011) and protecting group resources (Stahler et al. in J Anim Ecol 82: 222–234, 2013; Cassidy et al. in Behav Ecol 26:1352–1360, 2015). Here, we report 121 territorial aggressive inter-pack interactions in Yellowstone National Park between 1 April 1995 and 1 April 2011 (>5300 days of observation) and examine each interaction where one wolf interferes when its pack mate is being attacked by a rival group. This behavior was recorded six times (17.6 % of interactions involving an attack) and often occurred between dyads of closely related individuals. We discuss this behavior as it relates to the evolution of cooperation, sociality, and altruism.
