The relationship between testosterone and route-learning strategies in humans

The relationships between route-learning strategies and circulating testosterone and estradiol levels were investigated in men and women. Testosterone and estradiol concentrations were measured by salivary assays and route-learning strategies were assessed using a direction-giving paradigm based on a novel map. Testosterone was positively correlated with the use of male-biased route-learning strategies in men, but not in women. These findings suggest sex-specific patterns of relationships between circulating testosterone and spatial processing, which apply to everyday spatial behavior.     

Associations between financial strain and the diurnal salivary cortisol secretion of long-term unemployed individuals

Objective: The study investigated the associations between self-rated financial strain and overall diurnal salivary cortisol levels, as well as secretory patterns among long-term unemployed individuals.Methods: Psychosocial and life-style variables were assessed by means of questionnaires among 85 participants (mean age 42±9 years; 56% females). Salivary cortisol was sampled on four occasions during a 24-hour period and data was analysed separately for men and women.Results: Among females, high financial strain was related to higher overall cortisol levels, and to elevated levels in the evening. These associations did not reach significance among men. Multivariate analyses showed that evening levels of cortisol were positively associated with financial strain, but largely unrelated to life-style variables and psychological distress.Conclusions: The results suggest that high financial strain influences the diurnal cortisol secretion of unemployed individuals in terms of elevated cortisol levels in the evening. The mediating mechanisms are in need of further investigation.     

Guiding others for their own good: Action orientation is associated with prosocial enactment of the implicit power motive

Prior research has repeatedly documented how people who are implicitly motivated by power motives may hurt other people’s interests. However, people may also enact the implicit power motive (nPower) in a prosocial manner. Using an Operant Motive Test, the authors differentiated five enactment strategies within nPower and investigated personality antecedents and personal benefits of a prosocial enactment strategy. Two studies found that demand-related action orientation (i.e., ability to self-regulate positive affect) was associated with prosocial enactment of nPower. Furthermore, prosocial enactment of nPower was associated with a higher explicit power motive among future teachers (Study 1) and future psychologists (Study 2). Finally, there was an indirect effect of action orientation through the prosocial enactment of nPower on the explicit power motive (Studies 1 and 2) and, in turn, on well-being (Study 2). Our integration of motivation and self-regulation research (the “what” and “how” of goal striving) helps to better understand the dual nature of power motives.     

A 10-year prospective study of personality and reproductive success: Testing the mediating role of healthy living

Abstract

Objective: There is some evidence that personality relates to childbearing in adulthood but the importance of personality for reproductive capacity is unknown. This study explored cross-time associations between the major dimensions of trait personality and self-reported fertility and fecundity. Methods: A representative sample of young Australian adults [n?=?4501; age range ≈ 18–44 (women), 18–54 (men)] provided information on personality, fertility, fertility intentions, fecundity and lifestyle factors (cigarette smoking, alcohol consumption, physical activity) in 2006 and again in 2016. Older Australian adults [n?=?4359; age ≥?45 (women), ≥ 55 (men)] provided information on personality, lifestyle factors and completed fertility. Results: After controlling for sociodemographic factors, completed fertility was associated with higher agreeableness in both sexes, and lower conscientiousness and openness in women. In younger adults, higher levels of openness were associated with fewer children 10 years later in both sexes, and higher extraversion was associated with more children 10 years later in men. The association between fertility intentions and subsequent fertility was stronger among women scoring higher on conscientiousness, and women scoring higher on neuroticism were more likely to acquire medical or health difficulties in having children – an effect that was mediated by higher levels of cigarette smoking. Conclusions: The study provides initial evidence for an association between personality and the acquisition of difficulties in having children.     

The relationship between shame and guilt: cultural comparisons between Ireland and the United Arab Emirates

The current study examines whether proneness to shame and guilt is related to the cultural dimensions of collectivism and individualism. Two groups of participants from Ireland (n?=?120) and the United Arab Emirates (UAE) (n?=?115) completed measures assessing collectivism, individualism, and shame and guilt proneness. Results indicated that both samples displayed similar levels of individualism and collectivism. The UAE sample reported significantly higher levels of guilt proneness and shame proneness characterised by negative self-evaluation. In contrast, the Irish sample displayed significantly higher levels of shame characterised by withdrawal tendencies. Guilt was positively correlated with individualism, but shame was not correlated with either scores on collectivism or individualism. Young Arab women appear to experience higher levels of guilt and shame characterised by negative self-evaluation in comparison to their Irish counterparts who displayed higher levels of guilt proneness.     

The need for Power,sympathetic activation,and illness

This paper provides a brief summary of a number of recent research reports indicating thatn Power, if it is inhibited or stressed, is associated with high blood pressure and with the frequency and severity of infectious diseases. Other motive/stress or inhibition combinations failed to show these relationships. Blockedn Power apparently leads to chronic sympathetic activation, which, over time, results in high blood pressure and which increases epinephrine output that interferes with lymphocyte function, weakening the body's immune defenses against infectious diseases. On the other hand,n Power that is expressed successfully and rewarded may lead to better adaptation.     

Do Positive Self-Perceptions Have a “Dark Side”? Examination of the Link between Perceptual Bias and Aggression

The hypothesis that positive self-perceptions may have a dark side was investigated in the present study by examining the relationship between positively biased self-perceptions and aggression. Ratings of actual and perceived social acceptance of third-grade (n = 278), fourth-grade (n = 260), and fifth-grade (n = 321) students were compared to form a measure of perceptual bias. Peers provided nominations for overt and relational aggression. Gender differences were found for aggression (males were more overtly and relationally aggressive than females) but not perceptual bias. African-American children held more positive perceptions of their social acceptance and were perceived by peers as more aggressive than Caucasian children. Even after controlling for the effects of gender and ethnicity, more positively biased perceptions were associated with more peer nominations for overt and relational aggression. Contrary to an optimal range of bias hypothesis, even moderately positive self-perceptions were associated with elevated levels of aggression.     

Risk perception of a chronic threat of terrorism: Differences based on coping types,gender and exposure

High levels of risk perception of terrorism (RPT) may impair an individual's quality of life and welfare. To understand the mechanisms responsible for RPT, this study investigated the association of gender and coping styles with individual differences in two key elements of RPT: perceived control and perceived vulnerability. A convenience sample of 400 Israelis (181 men and 219 women) filled out questionnaires on sociodemographic background, RPT and coping. Employing a multidimensional approach for coping, we divided participants into four coping types: problem-focused (n = 65), emotion-focused (n = 70), mixed (n = 122) and minimal (n = 142). The results indicate that problem-focused coping is associated with higher levels of perceived control than other types of coping and mixed coping is associated with higher levels of perceived vulnerability than other coping strategies. Also, interactions between gender and exposure to terrorism contributed to understanding the differences in perceived control. The discussion addresses gender differences in RPT and coping in the context of traditional gender roles. The study concludes with implications for risk management and therapeutic interventions regarding high levels of fear of terrorism.     

Gender differences in power and self-disclosure in dating and married couples

The relationship between power and self-disclosure was studied for 20 dating and 20 married couples. Power and self-disclosure scales (of feelings and of accomplishments) were constructed and administered individually. We hypothesized that: (1) Women disclose more about feelings than men. (2) Men disclose more about accomplishments than women. (3) Power is positively correlated with disclosure of accomplishments. (4) Power is negatively correlated with disclosure of feelings and weaknesses. (5) Dating men are more powerful than dating women, but there are no gender differences in power in marriage. Hypotheses 1,3, and 5 were supported. Hypotheses 2 and 4 were rejected. Our findings revealed that there were no differences in power or disclosure of accomplishments between men and women for the total group. However, a significant interaction was found between gender and marital status for power. Dating men had more power than dating women, but married women had more power than married men. Last, women disclosed more feelings than men across both groups.     

Associations between psychological characteristics and indicators of metabolic syndrome among Chinese adults

Current knowledge about the relationship between psychological characteristics and metabolic syndrome (MetS) components is limited in Asian populations. The purpose of this study is to investigate linkages between physiological markers of MetS and life satisfaction, hostility, and depression in Chinese adults. Secondary analyses were conducted using cross-sectional data from parents of randomly selected middle school students participating in a pilot study in Qingdao, China. Among 440 parents who consented to participate (237 women, 203 men), 368 provided valid responses in all three categories of psychological characteristics, and only those subjects were included in these analyses. General linear models and logistic regressions were run separately by gender, controlling for covariates. Among women, life satisfaction was inversely associated with triglyceride levels (p = .04), LDL-C (p < .01), risk of hypertriglyceridemia (OR[.53], p < .01), HDL-C (OR[.78], p = .03), and MetS (OR[.52], p = .03). No associations were found between life satisfaction and any psychological characteristics among men. Among women, hostility was positively associated with triglyceride level (p = .04) and risk of hypertriglyceridemia (OR[2.12], p < .05). Among men, hostility was positively associated with waist circumference (p = .04), waist-hip ratio (p < .05), and fasting plasma insulin (p < .01). Depression was not associated with any physiological measurement in either gender. These findings indicate that relationships exist between certain psychological characteristics and physiological indicators of MetS among Chinese adults, although there may be important differences between genders.     

Student Ratings of a Male and Female Professors’ Lecture on Sex Discrimination in the Workforce

Using an experimental design, male (n = 41) and female (n = 46) undergraduate students in the southeastern USA evaluated an identical written lecture by a male and female professor on pay disparities between men and women in the workforce suggesting sex discrimination. Regardless of the students’ sex, the male professor and his lecture was rated more positively and less sexist than the female professor. Moderated multiple regression analysis indicated that more traditional and gender stereotypical attitudes toward women in male students were related to greater sexism ratings of the female professor compared to the male professor whereas; no differences on ratings of sexism between the male and female professor were found for male students with more liberal attitudes.     

Living with the unexplained: coping,distress, and depression among women with chronic fatigue syndrome and/or fibromyalgia compared to an autoimmune disorder

Chronic fatigue syndrome (CFS) and fibromyalgia are disabling conditions without objective diagnostic tests, clear-cut treatments, or established etiologies. Those with the disorders are viewed suspiciously, and claims of malingering are common, thus promoting further distress. It was hypothesized in the current study that levels of unsupportive social interactions and the coping styles used among those with CFS/fibromyalgia would be associated with perceived distress and depressive symptoms. Women with CFS/fibromyalgia (n = 39), in fact, reported higher depression scores, greater perceived distress and more frequent unsupportive relationships than healthy women (n = 55), whereas those with a chronic, but medically accepted illness comprising an autoimmune disorder (lupus erythematosus, multiple sclerosis, rheumatoid arthritis; n = 28), displayed intermediate scores. High problem-focused coping was associated with low levels of depression and perceived distress in those with an autoimmune condition. In contrast, although CFS/fibromyalgia was also accompanied by higher depression scores and higher perceived distress, this occurred irrespective of problem-focused coping. It is suggested that because the veracity of ambiguous illnesses is often questioned, this might represent a potent stressor in women with such illnesses, and even coping methods typically thought to be useful in other conditions, are not associated with diminished distress among those with CFS/fibromyalgia.     

Job resources and flow at work: Modelling the relationship via latent growth curve and mixture model methodology

The aim of the present three‐wave follow‐up study (n = 335) among employees of an employment agency was to investigate the association between job resources and work‐related flow utilizing both variable‐ and person‐oriented approaches. In addition, emotional exhaustion was studied as a moderator of the job resources–flow relationship, and as a predictor of the development of job resources and flow. The variable‐oriented approach, based on latent growth curve analyses, revealed that the levels of job resources and flow at work, as well as changes in these variables, were positively associated with each other. The person‐oriented inspection with the growth mixture modelling identified four trajectories based on the mean levels of job resources and flow and on the changes of these mean levels over time: (a) moderate work‐related resources (n = 166), (b) declining work‐related resources (n = 87), (c) high work‐related resources (n = 46), and (d) low work‐related resources (n = 36). Exhaustion was found to be an important predictor of job resources and flow, but it did not moderate their mutual association. Specifically, a low level of exhaustion was found to predict high levels of job resources and flow. Overall, these results suggest the importance of a person‐oriented view of motivational processes at work. In addition, in order to fully understand positive motivational processes it seems important to investigate the role of negative well‐being states as well.     

The Interrelations of Agency,Depression, and Suicidal Ideation Among Older Adults

The high rates of suicide among older men are cause for concern, and have prompted the investigation of factors that might explain these elevated rates. The current research examined whether the gender role construct agency was associated with depression and suicidal ideation among older adults. The results, based on self‐report data from a sample of older Australian men (n = 69) and women (n = 90), indicated that depression mediated the relation between agency and suicidal ideation. In addition, for older men only, agency moderated the depression‐suicidal ideation relation. The results suggest that older adults, and particularly men, with low levels of agency should be the targets for interventions aimed at increasing levels of agency and improving mental health.     

Regulatory focus systems and personal values

The present studies sought connections between two highly influential, but separate motivational systems: the regulatory foci and personal values. Study 1 (N = 173) showed that promotion focus was positively associated with Achievement and negatively with Tradition values, whereas prevention focus was positively associated with Conformity and Security values, and negatively with Self‐Direction and Stimulation values. Furthermore, interdependent self‐construal moderated trait prevention focus' associations with Power, Benevolence, Universalism, and Conformity values. Study 2 (N = 150) showed that a promotion‐framed message evoked more compliant behavior among those scoring high on Stimulation, Achievement, and Self‐Direction values, but that a prevention‐framed message evoked more compliance among those high in Conformity values. The results suggested that the regulatory foci are associated with certain values, and that these values may increase motivation in promotion‐ versus prevention‐relevant situations.

Leisure activities,caregiving demands and catecholamine levels in dementia caregivers

This study examined whether satisfaction from leisure activities moderates the relationship between caregiving demands (i.e., hours per day spent caring for a spouse with dementia) and resting levels of the catecholamines norepinephrine (NE) and epinephrine (EPI). Spousal caregivers (n?=?107; mean age?=?73.95?±?8.12 years) were assessed in home for plasma levels of NE and EPI, amount of care provided, and leisure satisfaction. Regression was used to determine whether leisure satisfaction moderated the relationship between hours providing care per day and catecholamine levels. A significant interaction was found between hours caregiving and leisure satisfaction for NE, but not for EPI. Post hoc regressions were conducted for both NE and EPI. At low leisure satisfaction, time spent caring for a spouse was positively associated with plasma NE (β?=?0.41; p?=?0.005) and EPI (β?=?0.44; p?=?0.003). In contrast, at high levels of satisfaction, time caregiving was not significantly associated with plasma NE (β?=?–0.08; p?=?0.57) or EPI (β?=?0.23; p?=?0.12). These findings suggest that leisure satisfaction may protect caregivers from increases in catecholamines, which have been implicated in cardiovascular risk. Further support for these findings may impact psychological treatments for distressed caregivers.     

Sexism as a Predictor of Attitudes Toward Women in the Military and in Combat

This study examined four forms of sexist beliefs as predictors of attitudes toward women in the military and in combat. Survey data revealed that military-affiliated college students (n = 62) held more negative attitudes than civilian students (n = 254) toward women in combat, but the groups did not differ on attitudes toward women in the military. All forms of sexism contributed uniquely to the prediction of attitudes toward women in the military, and 3 forms were associated with approval of women in combat. Sexist beliefs mediated the relationship between military-affiliation status and approval of women in combat.     

A Comparison of the Construct Validity of Two Alternative Approaches to the Assessment of Psychopathy in the Community

This study compared the validity of 2 different self-report approaches to the assessment of psychopathy in nonforensic samples: the Psychopathy Resemblance Index (PRI), derived from a measure of normal personality functioning, and the Self-Report Psychopathy Scale (SRP), developed specifically to assess the maladaptive traits associated with psychopathy. In 2 adult samples (n ₁ = 260, n₂ = 250), the PRI and the SRP were positively correlated with each other and with measures of maladaptive personality traits related to Machiavellianism and narcissism. However, unlike the SRP, the PRI was independent of trait empathy and general psychopathology and was positively associated with trait emotional intelligence. These results suggest that the PRI captures a more adaptive variant of psychopathy than does the SRP.     

Does a self management intervention lower distress in woman diagnosed with breast cancer?1

Psychological distress is particularly common with any cancer diagnosis. This paper examined the psychological distress in a cohort of women newly diagnosed with breast cancer and postulates on the underlying theory. A longitudinal study of a cohort of women (n = 147) diagnosed with breast cancer (within the past 1 year), was conducted at University Malaya Medical Centre, Kuala Lumpur. Data were collected at baseline and at post 4‐week intervention. Analysis of variance was conducted to examine for any significant differences in the change‐scores between the experimental group (n = 69) and the control group (n = 78). Using the change scores, analyses of variance showed significant differences between groups for stress, F(1, 140) = 13.68, p < .0001, anxiety F(1, 140) = 8.44, p < .004, and depression, F(1, 140) = 11.57, p < .0001. Levels of stress, anxiety and depression generally decreased significantly in the experimental groups, p < .05, but either maintained or increased in the control group. This study indicates that the level of psychological distress of women with breast cancer can be ameliorated with a 4‐week self‐management intervention. Lower stress levels were also found in women who reported engagement in higher physical activity than women with low physical activity.     

Reactive aggression tracks within‐participant changes in women's salivary testosterone

The relation between testosterone and aggression has been relatively well documented in men, but it is less well understood in women. Here we assessed the relationship between salivary testosterone and reactive aggression (i.e., rejection rate for unfair offers) in the Ultimatum Game. Forty naturally cycling women were tested twice, once in the late follicular phase (around ovulation) and once during the luteal phase. Ovulation was determined using urine test strips measuring luteinizing hormone levels. Salivary samples were assayed for testosterone, estradiol, progesterone, and cortisol at both test sessions. There was no association with the cycle, but multilevel modeling revealed a significant within‐participant association between testosterone and rejection rate for extremely unfair offers (i.e., high reactive aggression), indicating that women showed greater reactive aggression when their testosterone levels were higher. Additionally, we found that women with relatively high individual concentrations of testosterone were more likely to reject extremely unfair offers than women with relatively low concentrations of testosterone. This study is the first to demonstrate that women react more aggressively in response to provocation when their testosterone level is high than when their testosterone is low, suggesting that testosterone plays an important role in the regulation of women's aggressive behavior following social provocation.
