The effect of time pressure on risky choice behavior

Thirty six subjects chose individually between pairs of gambles under three time pressure conditions: High (8 seconds), Medium (16 seconds) and Low (32 seconds). The gambles in each pair were equated for expected value but differed in variance, amounts to win and lose and their respective probabilities. Information about each dimension could be obtained by the subject sequentially according to his preference.The results show that subjects are less risky under High as compared to Medium and Low time pressure, risk taking being measured by choices of gambles with lower variance or lower amounts to lose and win. Subjects tended to spend more time observing the negative dimensions (amount to lose and probability of losing), whereas under low time pressure they preffered observing their positive counterparts. Information preference was found to be related to choices.Filtration of information and acceleration of its processing appear to be the strategies of coping with time pressure.     

Gender differences in loss of psychological resources following experimentally-induced vicarious stress

The present research focuses on gender differences in resource loss, perceived threat, and negative affective reactions induced by experimental manipulation of vicarious stress. Israeli students (54.7% women) were randomly allocated to one of two conditions: (1) Threat Condition (n=98), in which participants were exposed to a video film depicting terror attacks and (2) Control Condition (n=30), in which participants viewed a video film depicting a series of non-emotive news broadcasts. Participants also completed measures of mastery, optimism, and self-esteem. The data indicated that whereas under the Threat Condition women scored lower on psychological resources and higher on perceived threat than men, no significant gender differences were observed under the Control Condition. A path analysis revealed that gender was directly related to perceived threat and resource loss, which, in turn, were related to negative affect. In addition, a greater sense of mastery was related to lower resource loss. Overall, these experimental findings suggest that gender and mastery bear prominent effects on cognitive and emotional reactions to vicarious life threat.     

Effects of an experimental social stressor on resources loss,negative affect,and coping strategies

This experimental study, grounded in Hobfoll's conservation of resources (COR) theory, assessed the effects of manipulating a social stressor on loss of psychological resources, negative affect, and coping strategies. Israeli student volunteers were randomly allocated to one of two conditions: (1) social stressor (n = 66) and (2.) nonstressor (n = 59). The social stressor, aimed at reducing participant's personal resources, was experimentally induced via the Trier Social Stress Test protocol. The protocol consisted of a mock job interview administered under evaluative conditions, followed by performing a difficult arithmetic calculation task. The nonstressor condition involved a neutral interaction with an experimenter, followed by performing a relatively easy mental calculation task. Consistent with our hypotheses, the social stressor, compared to the nonstressor condition, resulted in statistically significant lower mean levels of psychological resources, higher levels of negative affect, and increased emotion-oriented and avoidance-oriented coping. Furthermore, under the social stressor condition, compared with the nonstressor condition, negative affect was more strongly related to loss of psychological resources and various coping strategies. Overall, the data provide experimental support for key tenets of COR theory     

Anger In Or Out,Which Is Healthier? An Attempt To Reconcile Inconsistent Findings

Abstract

A survey of the literature concerning the relationship between style of anger expression and health disorders does not lead to a clear-cut conclusion. Some studies suggest that the outward expression of anger (anger-out) contributes to health problems of various types, while others present evidence suggesting that it is the suppression of anger (anger-in) which contributes to health problems. The present study examined three conceivable explanations for the contradictory evidence produced in this research area: (1) different aspects of anger expression are differentially related to the individual's health; (2) the pattern of anger expression is related differentially to health disorders of different types; (3) the degree of matching between the individual's style of anger expression and social desirability accounts for the inconsistency in the empirical findings. A sample of 134 men underwent comprehensive medical examinations and also filled in several anger expression questionnaires. The results supported the first hypothesis, namely that intensity of anger expression was negatively correlated with ill health while frequency of anger expression was positively correlated with ill health. No support was found for the hypothesis that anger expression relates differentially to health disorders of different types. However, the matching hypothesis was confirmed in part. It was found that individuals low on both intensity of anger expression and social desirability reported the highest frequency of health problems. The theoretical significance of these findings and their practical implications are discussed.     

Personal resources of mastery–optimism,and communal support beliefs,as predictors of posttraumatic stress in uprooted Israelis

Abstract

The study aims to assess the personal resources of mastery–optimism, and communal support beliefs, as predictors of posttraumatic stress and adaptation in uprooted Israelis following Israel's disengagement from the Gaza Strip and northern Samaria in the summer of 2005. A telephone interview of a sample of 104 respondents slated to be uprooted was conducted several weeks before the disengagement (T1), and again 9 months after the event (T2). At T1, respondents answered a questionnaire which included assessments of dispositional optimism and mastery, beliefs in the availability of community–family and governmental–societal support, nation-related anxiety, and demographic data. Posttraumatic stress levels were assessed at T2. The main findings showed that high levels of mastery–optimism and low nation-related anxiety at T1 predicted a low severity of total posttraumatic stress scores at T2. A high educational level and a secular identity also predicted low posttraumatic stress. In contrast, communal support beliefs were not related to posttraumatic stress. These findings point to the importance of personal resources and education as protective factors against posttraumatic stress following an event such as forced uprooting.     

Breaching the Contract: Aggressive Interpersonal Behaviors in Paternalistic Relationships

ABSTRACT

The study examined student evaluations (N?=?221) of frequency and impact of negative interpersonal behaviors by academic faculty and other students. As expected, negative behaviors by faculty was rated as less frequent but as more upsetting than those carried out by fellow students. The impact of such behaviors was not affected by the setting in which they occurred. However, students with a strong power motivation perceived negative behaviors by faculty as more upsetting than did students with a weak power motivation. The findings highlight the importance of covert restrictions on the exploitation of the potential power intrinsic in paternalistic relationships.     

Coping strategies and leadership in the adaptation to social change: The Israeli Kibbutz

This research assessed adaptation to community change in the Israeli kibbutz. A sample of 270 kibbutz members provided self-reports on their perception of the leaders of the change, change appraisals, coping strategies, and assessment of change outcomes. The main results showed that the perception of transformational leadership was negatively related to threat/loss and positively related to challenge/controllability appraisals; challenge/controllability appraisals were related positively to problem-focused coping and positive affect, whereas threat/loss appraisals were related positively to emotion-focused coping and negative affect. The findings contribute to an understanding of the stress and coping processes during a major change in a communal way of life, and underline the importance of leadership perception as a resource that contributes to better adaptation.     

Anxiety and bodily symptoms under the threat of missile attacks: The israeli scene

Abstract

The present research, conducted in Israel during the recent “Desert Storm” operation in the Gulf, sets out to assess the degree of anxiety and bodily symptoms of Israeli citizens, threatened by Scud missile attacks and undergoing a period of acute stress. Data were gathered via questionnaires distributed during the crisis period to over 500 respondents, most of them residing in Haifa, one of the high-risk areas for the missile attacks at the time. State anxiety was reported to be highly elevated during the crisis period, in comparison with norm group data collected during normal times. The most frequently reported bodily symptoms were changes in eating habits (loss of appetite or overeating), fatigue, and insomnia. Women reported more anxiety and bodily symptoms, on average, than men, as well as higher tension, fear and depression. The younger adults in the sample reported more anxiety and bodily symptoms, as well as tension, fear and depression, than their older counterparts. Lower levels of fear and depression were reported at the later stages of the crisis than at the earlier ones; most stress indicators evidenced lower levels with the passage of time. Finally, a strong positive relationship between anxiety and bodily symptoms was found, over and above the contribution of background variables and response tendencies. The possible explanations for the effects of background variables, as well as the strong relationship between anxiety and symptoms reported, are discussed.     

Aging holocaust survivors' well-being and adjustment: associations with ambivalence over emotional expression

A sample of 90 older respondents (age range: 78-83 years) composed of 2 Holocaust groups (camp inmates and other survivors) and a comparison group completed questionnaires measuring ambivalence over emotional expression, positive and negative affect, and psychosocial adjustment. The Holocaust groups rated higher than the comparison group on negative affect and ambivalence over emotional expression and lower on psychosocial adjustment. Ambivalence over emotional expression mediated the effects of the Holocaust on negative affect. These data suggest that the effects of the Holocaust are evident 60 years later, highlighting the role of ambivalence over emotional expression in the well-being of Holocaust survivors.     

Monitoring/Blunting and Social Support: Associations with Coping and Affect

The present study examined the associations of personal factors and social resources with coping and affective reactions to simulated stressful encounters. The study tested coping strategies and assessments of affect in the context of 'health' and 'work' threats described in 2 vignettes in a sample of 147 community residents. They also completed the Monitor-Blunter Style Scale (MBSS) and a perceived social support scale. The results showed positive associations between active coping and positive affect, and negative associations between avoidant coping and negative affect, replicating previous findings. Most interestingly, neither monitoring/blunting nor social support were directly related to either negative or positive affect, but were differentially related to coping strategies. Monitoring and social support were positively correlated with active coping and support-seeking in both vignettes, while blunting was related positively to avoidant coping, and social support was related negatively to this coping strategy. These results suggest that personal factors and social resources affect the use of coping strategies, rather than the affective reactions to threats, and contribute to our understanding of the stress and coping process.
