睾酮与人类决策行为

睾酮是一种类固醇激素, 主要的雄性激素之一。在神经科学与神经内分泌学领域中, 早期研究发现睾酮会对人类的攻击性、社会交往、冲动性等方面产生一定的影响; 后来心理学研究者开始关注睾酮与决策之间的关系, 包括社会性决策的信任、合作、利他与竞争方面以及经济性决策的风险决策。多项研究显示, 睾酮的水平与经济性决策中的风险寻求行为呈正相关关系; 在社会性决策领域中, 高睾酮水平的个体会表现出更高的攻击性、支配性和公平性行为, 同时表现出更低的人际信任。然而这些研究结果也存在难以重复验证的现象, 需要更多的研究探寻可能影响睾酮与决策的其他因素。未来对睾酮与决策的研究可以关注睾酮与消费决策领域、探寻青少年睾酮水平与社会行为的关系以及临床应用等。     

Emotional eating as a mediator between anxiety and cholesterol in population with overweight and hypertension

Although the relationship between cholesterol and mood states (especially anxiety) has been well studied, few researches have included the role of eating styles in this relationship. This study explored the associations among eating styles, negative emotional symptoms, and levels of cholesterol (and other medical variables) in a population with hypertension and overweight or obesity, analyzing the possible mediation mechanisms involved. A cross-sectional study was conducted in 68 adults with hypertension and overweight/obesity, and stepwise multiple regression analysis and mediation analyses were carried out to test the hypothesis that eating styles mediate the relationship between negative emotional symptoms and cholesterol. Several significant correlations among age, anthropometric, medical, and psychological variables (eating styles and negative emotional symptoms) were found. There was a significant indirect effect of anxiety on total cholesterol and LDL cholesterol through emotional eating. Results suggest that emotional eating has a relevant role in the rise in total and LDL cholesterol, acting as a mediator in the relationship between anxiety and cholesterol. This finding could have important implications, since it introduces a new variable in the relationship between emotions and cholesterol and, therefore, changes the way of understanding this relationship, and of treating high cholesterol in a hypertensive sample.     

Association of intimate partner violence with sociodemographic factors in married women: a population-based study in Iran

Intimate partner violence (IPV) is a neglected public health issue in Iran. This study was conducted among married women residing in urban Rasht (northern Iran), to estimate the prevalence and frequency of different forms of IPV from husband and their associations with socio-demographic factors. We carried out a population-based cross-sectional survey with cluster sampling design from February to October 2015. The samples consisted of married women aged ≥ 18 years with total household in Rasht city (north Iran) as the sample frame. We administered the Revised Conflict Tactics Scale (CTS-2) to estimate prevalence of past-year IPV. Of 2091 women, 57.1% had suffered psychological aggression, 27.6% physical abuse, 26.6% sexual abuse, and 6.9% injury. A significant association with IPV was found for women with, age ≤ 40 years, unemployed, low education, husband’s addiction and rented-householders. Women who experienced physical abuse, had less age at marriage than women without violence. Also women with sexual coercion had less length of marriage than other non-abused women. On logistic regression, the strongest predictor of psychological, physical and sexual abuse was unemployment of spouse, whereas for injury it was low educational level (<12 years) of women. Our findings suggest that risk of IPV is high in our population. There is an obvious need of preventive and treatment activities. Our findings point at that various forms of abuse are different from each other in terms of differing characteristics of the perpetrators and it might be that also different strategies are needed to reduce and prevent these violence. Confirmation by further research is needed.     

Associations of Emotional Abuse Types With Suicide Ideation Among Dating Couples

Numerous studies have demonstrated that coercive control is more strongly associated with suicidal ideation than other forms of intimate partner violence. However, a majority of these studies focused on samples of help-seeking women. This study examined whether coercive control remains the form of intimate partner violence most strongly associated with suicidal ideation within a sample of nonclinical dating couples. This cross-sectional, survey study on 104 dating couples examined the associations of coercive control (i.e., dominance/intimidation and restrictive engulfment) with suicidal ideation, while controlling for other forms of emotional abuse (i.e., hostile withdrawal and denigration), physical assault, and depressive symptoms. As expected, dominance/intimidation and depressive symptoms, but not denigration and physical assault, were associated with suicidal ideation. Contrary to our hypothesis, hostile withdrawal, but not restrictive engulfment, was associated with suicidal ideation. This study suggests that dominance/intimidation and hostile withdrawal are forms of emotional abuse that are pertinent to suicidal ideation in nonclinical dating couples.     

Applying the extended theory of planned behaviour to predict Chinese people's non‐remunerated blood donation intention and behaviour: The roles of perceived risk and trust in blood collection agencies

Against the backdrop of critical clinical blood shortage in China in recent years, the present research extends the theory of planned behaviour by incorporating two constructs potentially of importance in influencing non‐remunerated blood donation behaviour, namely perceived risk and individual trust in blood collection agencies to predict Chinese people's non‐remunerated blood donation intention and behaviour. A survey was conducted to measure variables of the theory of planned behaviour, and other variables such as experience of non‐remunerated blood donation, perceived risk and individual trust in blood collection agencies. Data to assess non‐remunerated blood donation behaviour were collected via phone interviews. Results of the path analysis are as follows. Subjective norm, perceived behavioural control and individual trust in blood collection agencies are all positively associated with attitudes toward non‐remunerated blood donation, explaining 46.9% of the variance in this variable. Perceived risk is negatively associated with blood donation intention, while subjective norm and attitudes toward non‐remunerated blood donation are both positively associated with blood donation intention. Together, the three variables account for 28.4% of the variance in donation intention. Both having a positive association with non‐remunerated blood donation behaviour, the combination of blood donation intention and donation experience explains 42.8% of its variance.     

Daily life with early orphanhood from HIV/AIDS: An exploratory study

This study explored the everyday lived life by South African early adolescents orphaned by HIV/AIDS. Informants were ten early adolescents (age range 12 to 14 years; females?=?6; males?=?4) from a low socioeconomic status neighbourhood of Johannesburg. The adolescents completed autobiographical essays and in-depth individual interviews on their quality of life in the school, home, and community. Thematic analysis of the data revealed the early adolescents, orphaned due to HIV/AIDS, to experience extreme sadness, anxiety, and fear. Their sense of emotional distress was compounded by living in material and relational poverty, with frequent exposure to bullying at school, and crime in their neighbourhood. Integrated psycho-social interventions addressing both material and relational poverty might enhance the physical and psycho-social well-being of adolescents with orphanhood from HIV/AIDS.     

Safe Danger – On the Experience of Challenge,Adventure and Risk in Education

This article reconsiders the presence and value of danger in outdoor and adventurous activities and sports in safety-conscious societies, especially in relation to the education of children and youth. Based on an original analysis of the relation between the concepts of ‘risk’ and ‘danger’, we offer an account of the relation between challenge, adventure, risk and danger, and emphasise the importance of teaching risk recognition, risk assessment, risk management and risk avoidance to children and youth, without the necessity of exposing them to jeopardy in dangerous situations. Our conclusion is that ‘Safe Danger’ describes what educators should seek, namely: the educational benefits of the challenges set by risk-taking and the demands of risk-facing, including those in adventurous situations, which are obtainable in the absence of significant danger, and which contribute to risk education. The educational value of adventurous and outdoor pursuits lies elsewhere than in the opportunities that they present for danger-facing, for example in their promotion of self-reliance, confidence, ability to team-work, and especially in their promotion of risk education, as an integral aspect of everyday life planning, as preparation for the day’s adventurous challenges, and as an instrument of task completion.     

Uncertainty,Indeterminacy, and Agent-Centred Constraints

Common-sense morality includes various agent-centred constraints, including ones against killing unnecessarily and breaking a promise. However, it's not always clear whether, had an agent ?-ed, she would have violated a constraint. And sometimes the reason for this is not that we lack knowledge of the relevant facts, but that there is no fact about whether her ?-ing would have constituted a constraint-violation. What, then, is a constraint-accepting theory (that is, a theory that includes such constraints) to say about whether it would have been permissible for her to have ?-ed? In this paper, I canvass various possible approaches to answering this question and I argue that teleology offers the most plausible approach—teleology being the view that every act has its deontic status in virtue of how its outcome (or prospect) ranks, relative to those of its alternatives. So although, until recently, it had been thought that only deontological theories can accommodate constraints, it turns out that teleological theories not only can accommodate constraints, but can do so more plausibly than deontological theories can.     

Adolescent risk-taking is predicted by individual differences in cognitive control over emotional,but not non-emotional,response conflict

While much research on adolescent risk behaviour has focused on the development of prefrontal self-regulatory mechanisms, prior studies have elicited mixed evidence of a relationship between individual differences in the capacity for self-regulation and individual differences in risk taking. To explain these inconsistent findings, it has been suggested that the capacity for self-regulation may be, for most adolescents, adequately mature to produce adaptive behaviour in non-affective, “cold” circumstances, but that adolescents have a more difficult time exerting control in affective, “hot” contexts. To further explore this claim, the present study examined individual differences in self-control in the face of affective and non-affective response conflict, and examined whether differences in the functioning of cognitive control processes under these different conditions was related to risk taking. Participants completed a cognitive Stroop task, an emotional Stroop task, and a risky driving task known as the Stoplight game. Regression analyses showed that performance on the emotional Stroop task predicted laboratory risk-taking in the driving task, whereas performance on the cognitive Stroop task did not exhibit the same trend. This pattern of results is consistent with theories of adolescent risk-taking that emphasise the impacts of affective contextual influences on the ability to enact effective cognitive control.     

How Does Explicit Versus Implicit Risk Information Influence Adolescent Risk‐Taking Engagement?

Adolescents have been shown to be more likely to engage in risky behaviors in daily life. Many studies have indicated that adolescents could make advantageous choices when they receive explicit information but could fail to choose advantageously when they are not informed about risks. The current study aimed to examine the influence of explicit risk information (i.e., when risk information is directly available) versus implicit risk information (i.e., when risk information has to be learned from feedback) on risk‐taking engagement, in order to clarify whether the enhanced risk‐taking observed in decision making under ambiguity in adolescents results from either a greater exploration of ambiguous situations (i.e., a higher ambiguity tolerance) or a specific difficulty associated with learning based on previous choices' outcomes. Adolescents and young adults completed a new adaptation of the Balloon Analogue Risk Task. They were required to accumulate as many points as possible by inflating balloons associated with variable break points and avoiding explosions. This adaptation involved a manipulation of the information level with two conditions, an “informed” condition and a “noninformed” condition, in which the participants had to learn the matching of colors with balloons' resistances based on feedback. The results demonstrated that providing explicit risk information allows adolescents to be as efficient as adults at the end of the game. In contrast, adolescents failed to adjust risk‐taking to the balloon resistance in the noninformed condition. These findings critically suggest that this failure reflects a specific impairment of feedback‐based learning ability but not a global excess of risk‐taking during adolescence.
