The Ape That Kicked the Hornet's Nest: Response to Commentaries on “The Ape That Thought It Was a Peacock”

We respond to the commentaries on our target article, “The Ape That Thought It Was a Peacock.” We start with specific issues raised by the article. These relate to the magnitude of human sex differences; the evolution and relative importance of pair bonding, paternal care, and polygyny in our species; and the distinction between the males-compete/females-choose (MCFC) model of human sexual psychology and the mutual mate choice (MMC) model. We then evaluate two competing theories of human sex differences and similarities: Social Role Theory and Attachment Fertility Theory. We conclude with some thoughts about how to present and teach evolutionary psychological research and theories without conveying an exaggerated impression of the scale of human sex differences.     

GLOMOsys: A Systems Account of Global Versus Local Processing

Within GLOMO^sys (the GLObal versus LOcal processing MOdel, a systems account) we examine the functionalities of two processing systems that process information either globally or locally (looking at the forest vs. the trees). GLOMO^sys suggests that (a) global versus local perceptual processing carries over to other tasks; (b) perceptual processing is related to conceptual processing (e.g., creative/analytic tasks; face/verbal recognition; similarity/dissimilarity generation; abstract/concrete construals, distance estimates, inclusive/exclusive categorization; assimilation/contrast in social judgments); (c) perceptual and conceptual processing is elicited by real-world variables (e.g., mood, exteroceptive and interoceptive cues of approach/avoidance, promotion/prevention focus, high/low power, distance, obstacles, novelty/familiarity, love/sex, interdependent/independent selves); (d) regulatory focus, psychological distance, and novelty are driving effects; and (e) the global system (glo-sys) processes novelty and the local system (lo-sys) processes familiarity. We discuss whether glo-sys is responsible for understanding meaning, relate the systems to physiological research, and discuss new research questions.     

The Concept of Identification in Threat Assessment

Identification is one of eight warning behaviors—superordinate patterns of accelerating risk—that are theorized to correlate with targeted violence, and have some empirical validation. It is characterized by one or more of five characteristics: pseudo-commando behavior, evidence of a warrior mentality, a close association with weapons or other military or law enforcement paraphernalia, wanting to imitate and often surmount previous attackers or assassins, or believing oneself to be an agent to advance a particular cause or belief system. The authors briefly explore the history of the psychology of identification, its current usage, and its application to threat assessment. Four cases are used to illustrate identification as both a process and a product, and a likely motive for targeted violence in some subjects. Its operational relevance for threat assessment is suggested. Copyright © 2015 John Wiley & Sons, Ltd.     

Begutachtung der posttraumatischen Belastungsstörung

There is a high prevalence of posttraumatic stress disorder in community-based samples; therefore psychiatric assessment and expert opinion is often required. Professional standards of psychiatric expert opinion in the assessment of posttraumatic stress disorder are outlined. The significance of symptom validity tests is critically discussed. Test results have to be considered carefully in the medicolegal context and require thorough clinical assessment.     

A closer look at the discrimination outcomes in the IAT literature

To what extent the IAT (Implicit Association Test, Greenwald et al., 1998) predicts racial and ethnic discrimination is a heavily debated issue. The latest meta‐analysis by Oswald et al. (2013) suggests a very weak association. In the present meta‐analysis, we switched the focus from the predictor to the criterion, by taking a closer look at the discrimination outcomes. We discovered that many of these outcomes were not actually operationalizations of discrimination, but rather of other related, but distinct, concepts, such as brain activity and voting preferences. When we meta‐analyzed the main effects of discrimination among the remaining discrimination outcomes, the overall effect was close to zero and highly inconsistent across studies. Taken together, it is doubtful whether the amalgamation of these outcomes is relevant criteria for assessing the IAT's predictive validity of discrimination. Accordingly, there is also little evidence that the IAT can meaningfully predict discrimination, and we thus strongly caution against any practical applications of the IAT that rest on this assumption. However, provided that the application is thoroughly informed by the current state of the literature, we believe the IAT can still be a useful tool for researchers, educators, managers, and students who are interested in attitudes, prejudices, stereotypes, and discrimination.     

Virtual social environments as a tool for psychological assessment: dynamics of interaction with a virtual spouse

Computer games are advocated as a promising tool bridging the gap between the controllability of a lab experiment and the mundane realism of a field experiment. At the same time, many authors stress the importance of observing real behavior instead of asking participants about possible or intended behaviors. In this article, the authors introduce an online virtual social environment, which is inhabited by autonomous agents including the virtual spouse of the participant. Participants can freely explore the virtual world and interact with any other inhabitant, allowing the expression of spontaneous and unprompted behavior. The authors investigated the usefulness of this game for the assessment of interactions with a virtual spouse and their relations to intimacy and autonomy motivation as well as relationship satisfaction with the real-life partner. Both the intimacy motive and the satisfaction with the real-world relationship showed significant correlations with aggregated in-game behavior, which shows that some sort of transference between the real world and the virtual world took place. In addition, a process analysis of interaction quality revealed that relationship satisfaction and intimacy motive had different effects on the initial status and the time course of the interaction quality. Implications for psychological assessment using virtual social environments are discussed.     

Attacks on German public figures, 1968-2004: warning behaviors, potentially lethal and non-lethal acts, psychiatric status, and motivations

Fourteen non-terrorist attackers of public figures in Germany between 1968 and 2004 were intensively studied, with a particular focus on warning behaviors, attack behaviors, and the relationship between psychiatric diagnosis, symptoms, and motivations for the assault. A large proportion of the attackers were severely mentally ill, and most likely to be in the potentially lethal rather than the non-lethal group. A new typology of seven warning behaviors was applied to the data, and all were present, most frequently fixation and pathway warning behavior, and least frequently a direct threat. Psychiatric diagnosis could be closely linked to motivation when analyzed at the level of symptom and content of thought, often delusional. Most of the attacks were directed at political figures, and the majority occurred after 1995.     

Suche nach der Ursache des chronischen Ersch?pfungssyndroms

The etiology of chronic fatigue syndrome is subject to a longstanding controversy between scientists, healthcare providers, patients and self-help groups. The reasons for this, sometime heated, dispute are most likely not only due to the diversity and complexity of scientific facts alone but can also be seen as the consequences of the desired legitimation or dreaded delegitimation of the syndrome by the respective etiological model. The mechanisms of these processes will be described one the basis of the current discussion regarding the role of xenotropic murine leukemia virus-related virus in chronic fatigue syndrome.
