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。     

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.     

Conversation: The challenges of teaching in a “nano department”

A panel at the 2016 American Academy of Religion conference staged, taped, transcribed, and edited this conversation about the challenges and opportunities of teaching in a “nano department” – an undergraduate religion or religious studies department (or combined religion and philosophy department) with only one, two, or three faculty members. Two things quickly become evident: one is the impossibility of coverage of the full religious studies curriculum, and the other is the necessity for collaboration with other departments. Neither of these is unique to nano departments, but there exists an intimacy between students and faculty in small departments, a necessary freedom to rethink the place of the study of religion in the liberal arts curriculum, and a disruptive value in what can be critiqued and contributed from a marginalized position. Arguably, nano departments are the canaries in the academic coal mine, charting the future of the humanities that cannot be discerned from the vantage point of Research‐1 contexts.     

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.     

Adult's amae as a tool for adjustment to a new environment

Past research has found that people of East Asian backgrounds avoid seeking help out of relational concerns. Research on amae, however, suggests that Japanese may use amae to simultaneously obtain the needed help and enhance relationships. Study 1 showed that among Japanese entrepreneurs and managers, the propensity toward amae correlated with perceiving fewer costs of help‐seeking, seeking more help at work, greater engagement in new relationships and higher general trust. These associations suggest that the Japanese may be using amae to get the help they need and to build new relationships. Study 2 further showed that first‐year undergraduates who reported engaging in amae soon after entering college showed a significant increase in sense of purpose and satisfaction with college life in their first year. These findings suggest that, unlike dependency or passive love, amae can be highly adaptive for the Japanese.     

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.     

An exploration of the benefits of animal‐assisted activities in undergraduate students in Singapore

The rise in psychological problems, attrition, and suicide rates of university students has been linked to the stressful challenges faced during university life. To buffer this, animal assisted activities (AAA) may assist in improving psychological and physiological well‐being in students, however, to date, there is little empirical evidence for their effectiveness. Consequently, this study explored the psychological and physiological benefits of AAA in a sample of undergraduate students. Sixty‐two students from two local universities participated in an hour‐long AAA session delivered by Therapy Dogs Singapore. Measures of perceived stress, anxiety, state self‐esteem, and blood pressure (BP) were taken before and after the sessions. The results indicated that students experienced significant decreases in state anxiety, systolic, and diastolic BP post AAA, and when compared to a quiet reading comparison session. State self‐esteem increased post AAA and, further, was found to moderate the change in anxiety in addition to perceived stress, whereby perceived anxiety reduced more in those with low state self‐esteem and high perceived stress. These results suggest that AAA can be an effective intervention for stress among undergraduate students, which utilizes a novel, easy to implement and enjoyable approach for Singaporean students.     

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.     

Self‐efficacy or perceived behavioural control: Which influences consumers' physical activity and healthful eating behaviour maintenance?

This research investigated the role of a commercial program, Michelle Bridges 12 Week Body Transformation (MB12WBT), that uses a variety of tools including social support to influence weight management behaviours such as exercising and eating healthfully. The need for research into weight management remains current given obesity rates have continued to increase in recent decades. Weight management is a complex behaviour that for many consumers involves barriers that influence their commitment to continue exercising and eating healthily. The Theory of Planned Behaviour is frequently used to explain, and to a lesser extent predict, behaviours such as physical activity and healthy eating; however, there is much debate as to whether a perceived behavioural control variable or self‐efficacy is the best predictor of behaviour. Structural equation modelling was used to analyse data from a sample of 724 respondents who answered a baseline and three month follow‐up survey. The analysis revealed self‐efficacy and perceived behavioural control were two distinct constructs. Self‐efficacy was a better predictor of behaviour than perceived behavioural control variables as suggested in the original Theory of Planned Behaviour. Furthermore, self‐efficacy had a significant impact on exercising and eating healthfully behaviour. The findings and implications for both behaviour change theory and practice are discussed.
