Age at menarche and digit ratio (2D:4D): relationships with body dissatisfaction, drive for thinness, and bulimia symptoms in women

This study examined the hypothesis that lower prenatal androgen exposure and earlier puberty are associated with more dysfunctional eating attitudes and behaviors. Relationships between both age at menarche (AAM) and 2D:4D (a marker of prenatal androgen exposure), and EDI-2-Body Dissatisfaction, EDI-2-Drive for Thinness, and EDI-2-Bulimia scores, were examined in women using correlations and regressions. Earlier menarche was associated with higher drive for thinness after controlling for BMI and negative affect, but only in women who were not exclusively heterosexual. Higher 2D:4D was associated with higher Bulimia and Body Dissatisfaction scores, but only in exclusively heterosexual women, and relationships disappeared when covariates were controlled. Later AAM and higher 2D:4D were unique predictors of higher Bulimia scores for exclusive heterosexuals when BMI was controlled. These findings suggest future research should examine sexual orientation as a mediator or moderator of prenatal and postnatal organizational hormonal effects on women's disordered eating attitudes and behaviors.     

Myopic loss aversion: Demystifying the key factors influencing decision problem framing

Advancement of myopic loss aversion theory has been hamstrung by conflicting results, methodological inconsistencies, and a piecemeal approach toward understanding the key factors influencing decision problem framing. A series of controlled experiments provides a more holistic view of the variables promoting myopia. Extending the information horizon promotes broad framing, which propels risk. Evaluation frequency and decision frequency interact regardless of information horizon, supporting the notion that restricting either mechanism alleviates myopia. When conducting evaluations infrequently, neither segregating nor aggregating retrospective returns significantly alters risk preferences. Moreover, students and real retirement plan participants exhibit comparable appetites for risk, implying that both groups frame decision problems similarly. Explanations for these findings and avenues for future research are discussed.     

Inanspruchnahme psychosozialer Versorgungsstrukturen

In spite of the high proportion of persons with a migration background in Germany, professional mental health care utilization by this population group still seems to be insufficient. This could be due to social as well as structural and individual barriers which impede the professional mental health care-seeking process. The heuristic Mental Health Action Process Approach (M-HAPA) model was developed in order to be able to empirically investigate the specific mechanism of action as well as the specific time of influence of these factors. An empirically supported model should possibly be able to justify targeted interventions. The M-HAPA model describes mental health care utilization behavior, combines the basic ideas of already existing models describing health behavior and health care utilization behavior as well as factors which are specifically relevant for the health care utilization behavior of persons with a migration background. This combination may serve as a basis for future research in the field of mental health care utilization behavior of persons with a migration background.     

Artificial Intelligence and Medical Humanities

The use of artificial intelligence in healthcare has led to debates about the role of human clinicians in the increasingly technological contexts of medicine. Some researchers have argued that AI will augment the capacities of physicians and increase their availability to provide empathy and other uniquely human forms of care to their patients. The human vulnerabilities experienced in the healthcare context raise the stakes of new technologies such as AI, and the human dimensions of AI in healthcare have particular significance for research in the humanities. This article explains four key areas of concern relating to AI and the role that medical/health humanities research can play in addressing them: definition and regulation of “medical” versus “health” data and apps; social determinants of health; narrative medicine; and technological mediation of care. Issues include data privacy and trust, flawed datasets and algorithmic bias, racial discrimination, and the rhetoric of humanism and disability. Through a discussion of potential humanities contributions to these emerging intersections with AI, this article will suggest future scholarly directions for the field.

     

THE FRUITS OF PLURALISM: A VISION FOR THE NEXT SEVEN YEARS IN RELIGION/SCIENCE

This article offers a vision for work at the intersection of science and religion over the coming seven years. Because predictions are inherently risky and are more often than not false, the text first offers an assessment of the current state of the science‐religion discussion and a quick survey of the last 50 years of work in this field. The implications of the six features of this vision for the future of the field are then presented in some detail. Rather than bemoaning the current diversity of approaches and conclusions as a negative result, I endorse it as a healthy sign—if acknowledged honestly and managed well.     

Western scrub-jays allocate longer observation time to more valuable information

When humans mentally reconstruct past events and imagine future scenarios, their subjective experience of mentally time travelling is accompanied by the awareness of doing so. Despite recent popularity of studying episodic memory in animals, such phenomenological consciousness has been extremely difficult to demonstrate without agreed behavioural markers of consciousness in non-linguistic subjects. We presented western scrub-jays (Aphelocoma californica) with a task requiring them to allocate observing time between two peepholes to see food being hidden in either of two compartments, one where observing the hiding location was necessary to later relocate the food, and another where food could easily be found without watching. Jays first separately experienced these consequences of possessing information in each compartment and subsequently, once given a choice, made more looks and spent more time looking into the compartment where information was necessary than into the compartment where it was unnecessary. Thus, the jays can collect information to solve a future problem. Moreover, they can differentiate sources of information according to their potential value and modify behaviour to efficiently collect important, usable information. This is the first evidence of metacognition in a species that passes the behavioural criteria for both retrospective and prospective mental time travel.     

Reduced attentional capture in action video game players

Recent studies indicate that playing action video games improves performance on a number of attention-based tasks. However, it remains unclear whether action video game experience primarily affects endogenous or exogenous forms of spatial orienting. To examine this issue, action video game players and non-action video game players performed an attentional capture task. The results show that action video game players responded quicker than non-action video game players, both when a target appeared in isolation and when a salient, task-irrelevant distractor was present in the display. Action video game players additionally showed a smaller capture effect than did non-action video game players. When coupled with the findings of previous studies, the collective evidence indicates that extensive experience with action video games may enhance players’ top-down attentional control, which, in turn, can modulate the negative effects of bottom-up attentional capture.     

Who Fights,Who Flees? An Integration of the LC4MP and Psychological Reactance Theory

ABSTRACT

This study tests the hypothesis that defensive message processing, like defensive behaviors in the real world, has two directions, fight-and-flight. The Limited Capacity Model of Motivated Mediated Message Processing (LC4MP) characterizes defensive message processing by increases in unpleasantness and arousal reports, and accelerated heart rate indicating either a focus on internal processing (internal thoughts) or the active withdrawal of cognitive resources from processing highly arousing and unpleasant media messages. However, the LC4MP has not included direct measures that allow discrimination between fight-and-flight responses. Psychological reactance theory (PRT) predicts defensive responses including anger and counterarguments (reactance) when media messages threaten viewers’ freedom and autonomy. We hypothesized that PRT provides the LC4MP with the appropriate measures (anger and counterarguments) needed to discriminate fight-or-flight responses. Results supported this prediction. Participants (N = 49 adult-smokers) high in defensive and low in appetitive reactivity (risk-avoiders) withdrew from the message (fled: characterized by low anger and counterarguments) while those high in appetitive and low in defensive reactivity (risk-takers) experienced reactance (fought: characterized by high anger and counterarguments) in response to freedom threatening antitobacco messages that are highly arousing and unpleasant. Moreover, both reactance and message withdrawal yielded the same cognitive, emotional, and physiological responses predicted by the LC4MP as indicators of defensive message processing. Theoretical and message design recommendations are discussed.
