Walking activity and emotional distress among breast cancer survivors: the parallel mediating effects of posttraumatic growth and body image
Purpose
Although the antidepressant effects of physical activity have been well established, the underlying psychological mechanisms are understudied among cancer survivors. The present study aims to examine the parallel mediating effects of posttraumatic growth and body image on the association between walking activity and emotional distress (anxiety and depression) among Chinese breast cancer survivors.
Methods
Chinese breast cancer survivors (
n
= 235) completed a cross-sectional questionnaire that assessed walking activity, anxiety, depression, posttraumatic growth, and body image over the past week. Path analysis was conducted to test the hypothesized mediation model.
Results
The hypothesized model was supported: walking activity was positively associated with posttraumatic growth and body image satisfaction, which were then negatively associated with anxiety and depression. After controlling for the mediators, the direct effect of physical activity on depression was still significant, whereas the direct effect of physical activity on anxiety was no longer significant.
Conclusion
Our findings suggest that posttraumatic growth and body image may be essential psychological pathways underlying the association between walking activity and emotional distress among Chinese breast cancer survivors. Researchers and health practitioners should consider supplementing physical activity interventions with mental health services that facilitate psychological growth and a positive body image to enhance the potential psychological benefits of physical activity.

Thoughts on Integrating Evolutionary Analysis into Sociological Action Theory
It is explored if and to what extent two approaches in behavioral sciences, which are promising with respect to an evolutionary grounded, integrative action theory, are actually compatible. These two approaches are, on the one hand, evolutionary psychology, which conceptualizes human nature as a collection of evolved psychological mechanisms, each being functionally specialized with respect to a specific problem of adaptation. And on the other hand, the dual-process perspective, which holds that human behavior is driven by the interplay of two qualitatively distinct types of cognitive processes: Autonomous, fast, and associative Type 1 processes, which operate outside of the consciousness of the actor, on the one hand, and controlled, slow, and rule-based Type 2 processes of which the actor is aware. Notably, both of these approaches have descendants in modern sociological action theory, i.e., goal-framing theory (Lindenberg 2008, 2009) and the model of frame-selection (Esser 2001; Kroneberg 2011). It is argued that evolutionary psychology and the dual-process perspective are largely compatible, thereby giving rise to an evolutionary grounded, integrative action theory. Accordingly, Type 1 processes can be traced back to evolutionary old cognitive modules, which humans share with other species and which are highly efficient at solving specific problems of adaptation in a stable environment. In contrast, Type 2 processes of higher cognition are distinctly developed in humans and highly effective at dealing with a rapidly changing life space.

States in Mind: Evolution, Coalitional Psychology, and International Politics
The use of evolutionary models to examine political behavior in international relations has been the subject of much debate, but serious scholarly work has generally been lacking, in part because the causal mechanisms have not always been clearly explicated. An evolutionary psychological framework can correct this deficit and benefit research in at least three major areas of international relations: (1) how political groups such as states are perceived and represented by individuals and groups; (2) how coalitional action is facilitated among states; and (3) sex differences in coalitional behavior. Hypotheses are offered in each of these areas to more clearly demonstrate the psychological mechanisms that are the bridge between evolutionary theory and political behavior in the international system. The social and political landscape of the ancestral environments in which humans evolved strongly suggests that the psychological architecture of humans possesses specialized design for coalitional living that continues to guide behavior in the modern political world. These evolved mechanisms structure human motivation and engagement in areas including leadership and war.

Conspiracy Theories: Evolved Functions and Psychological Mechanisms
Belief in conspiracy theories—such as that the 9/11 terrorist attacks were an inside job or that the pharmaceutical industry deliberately spreads diseases—is a widespread and culturally universal phenomenon. Why do so many people around the globe believe conspiracy theories, and why are they so influential? Previous research focused on the proximate mechanisms underlying conspiracy beliefs but ignored the distal, evolutionary origins and functions. We review evidence pertaining to two competing evolutionary hypotheses: (a) conspiracy beliefs are a by-product of a suite of psychological mechanisms (e.g., pattern recognition, agency detection, threat management, alliance detection) that evolved for different reasons, or (b) conspiracy beliefs are part of an evolved psychological mechanism specifically aimed at detecting dangerous coalitions. This latter perspective assumes that conspiracy theories are activated after specific coalition cues, which produce functional counterstrategies to cope with suspected conspiracies. Insights from social, cultural and evolutionary psychology provide tentative support for six propositions that follow from the adaptation hypothesis. We propose that people possess a functionally integrated mental system to detect conspiracies that in all likelihood has been shaped in an ancestral human environment in which hostile coalitions—that is, conspiracies that truly existed—were a frequent cause of misery, death, and reproductive loss.

Mechanisms Linking Social Ties and Support to Physical and Mental Health
Over the past 30 years investigators have called repeatedly for research on the mechanisms through which social relationships and social support improve physical and psychological well-being, both directly and as stress buffers. I describe seven possible mechanisms: social influence/social comparison, social control, role-based purpose and meaning (mattering), self-esteem, sense of control, belonging and companionship, and perceived support availability. Stress-buffering processes also involve these mechanisms. I argue that there are two broad types of support, emotional sustenance and active coping assistance, and two broad categories of supporters, significant others and experientially similar others, who specialize in supplying different types of support to distressed individuals. Emotionally sustaining behaviors and instrumental aid from significant others and empathy, active coping assistance, and role modeling from similar others should be most efficacious in alleviating the physical and emotional impacts of stressors.

Two Strikes: Race and the Disciplining of Young Students
There are large racial disparities in school discipline in the United States, which, for Black students, not only contribute to school failure but also can lay a path toward incarceration. Although the disparities have been well documented, the psychological mechanisms underlying them are unclear. In two experiments, we tested the hypothesis that such disparities are, in part, driven by racial stereotypes that can lead teachers to escalate their negative responses to Black students over the course of multiple interpersonal (e.g., teacher-to-student) encounters. More generally, we argue that race not only can influence how perceivers interpret a specific behavior, but also can enhance perceivers' detection of behavioral patterns across time. Finally, we discuss the theoretical and practical benefits of employing this novel approach to stereotyping across a range of real-world settings.

Individual Differences in Women’s Rape Avoidance Behaviors
Rape can exact severe psychological, physical, and reproductive costs on women, and likely was a recurrent adaptive problem over human evolutionary history. Therefore, women may have evolved psychological mechanisms that motivate rape avoidance behaviors. Guided heuristically by an evolutionary perspective, we tested the hypothesis that women’s rape avoidance behaviors would vary with several individual difference variables. Specifically, we predicted that rape avoidance behaviors would covary positively with (1) women’s attractiveness, (2) women’s involvement in a committed romantic relationship, and (3) the number of family members living nearby. We also predicted that women’s rape avoidance behaviors would covary negatively with age. We administered the Rape Avoidance Inventory (McKibbin et al., Pers Indiv Differ 39:336–340, 2009) and a demographic survey to a sample of women (
n
= 144). The results of correlational and regression analyses were consistent with the predictions, with the exception that women’s rape avoidance behaviors did not covary with women’s age. Discussion highlighted limitations of the current research and directions for future research on women’s rape avoidance psychology and behaviors.

Toward a Mechanistic Understanding of Links Between Close Relationships and Physical Health
Although researchers have made great strides in identifying links between close relationship processes and physical health, we know less about the psychological and behavioral mechanisms underlying these links. As we move toward considering relationships as a public health issue, understanding mechanistic pathways in relationships–health links is crucial for designing efficient and effective interventions. In this review, we outline criteria for establishing a construct as a relationships–health mechanism. We then discuss how best to test potential mechanisms of relationships–health links and identify some promising mechanism candidates on the basis of initial evidence (emotion, attachment, sleep, and substance abuse). We conclude by recommending key directions for future research.
