The effects of attentional training on physiological stress recovery after induced social threat

Abstract

Social stress has been related to both physiological and psychological responses. The recovery of stress is influenced by the way environmental information is processed, i.e., what information is attended to and how it is interpreted. The present study investigated the effect of attention modification training on physiological stress recovery following induced stress. A group of applicants preparing for a job interview were randomly allocated to an attention training condition versus a control condition. Afterwards, they were asked to give an artificial job interview to a real life jury while being videotaped. Participants in both conditions showed decreased heart rate variability during the job interview, which indicates an overall physiological stress response. However, during a 30-minute follow-up period after the training, indices of heart rate variability showed improved stress recovery only in the attention training condition. Attentional training is proposed as a promising strategy to prevent enduring stress reactions.     

Search for a curvilinear relationship between the sense of coherence and the intensity of PTSD in MVA survivors

Abstract

The relationship between the sense of coherence (SOC) and the intensity of posttraumatic stress disorder (PTSD) was examined in order to determine its nature and to resolve the inconsistencies between (1) a growing body of empirical research that indicates a linear relationship between these variables, and (2) the schema-based theories of PTSD that suggest a curvilinear relationship between cognitions and the intensity of PTSD. In this cross-sectional study an attempt was also made to identify some psychological factors that moderate this relationship. Participants were a sample of 1132 motor vehicle accident (MVA) survivors. The results showed that gender and temperamental predisposition to PTSD constituted moderator variables of the relationship between SOC and the intensity of PTSD. This supported both the empirical evidence on the linear and negative relationship between SOC and the intensity of PTSD and the theories that postulated the curvilinear relationship.     

Main and interactive effects of social support in predicting mental health symptoms in men and women following military stressor exposure

Abstract

Evidence across a multitude of contexts indicates that social support is associated with reduced risk for mental health symptoms. More information is needed on the effectiveness of different sources of support, as well as sex differences in support. Associations between social support from two sources – the military unit and friends and family – and mental health symptoms were examined in a study of 1571 Marine recruits assessed at the beginning and end of a highly stressful 13-week training program. Military social support buffered the stressor exposure–posttraumatic stress symptomatology (PTSS) relationship, whereas the relationship between stressor exposure and PTSS was highest when civilian social support was high. Further inspection of the interactions revealed that military support was most important at high levels of stressor exposure. Sex differences in the relationship between social support and symptoms were found, such that support from military peers was associated with lower levels of PTSS for men, whereas civilian support was associated with lower PTSS for women. While civilian social support was associated with lower levels of depression symptom severity in both women and men, the relationship was stronger for women. Reviewed implications focus on the importance of considering the recipient, source, and context of social support.     

Sexual Harassment: Prevalence,Outcomes, and Gender Differences Assessed by Three Different Estimation Methods

This study investigates gender differences in prevalence and effects of sexual harassment using three different estimation methods. In a representative sample of 2,349 Norwegian employees, 1.1% self-labeled as targets of sexual harassment, whereas 18.4% reported exposure to sexually harassing behaviors during the last six months. When employing latent class cluster analysis as a method for estimating prevalence of sexual harassment, 2.2% could be classified as targets of frequent harassment and 19.1% could be classified as targets of unwanted sexual attention. Although more women than men self-labeled as targets of sexual harassment, men reported the same number of sexually harassing behaviors as women. Sexual harassment was found to be significantly related to mental health problems and low job satisfaction among men and women.     

Is attention necessary for perceiving gaze direction? It depends on how you look at it: Evidence from the locus-of-slack method

Several researchers have studied how we process and perceive gaze direction. However, it is still unclear at which perceptual stage of gaze processing (encoding or/and categorization), attention is required to judge gaze direction. We report a study in which we manipulated the difficulty of gaze perceptual judgements (easy vs. difficult) and used the locus-of-slack method to test the role of different types of attention (spatial and central) in the encoding and categorization of gaze direction. In Experiment 1 we used the spatial cueing paradigm to investigate if gaze direction judgements can be carried out while spatial attention is diverted. In Experiment 2 we used the psychological refractory period (PRP) paradigm to determine whether judgement of gaze direction involves central attention processes. The findings demonstrate that gaze judgements require input attention (both for the encoding and categorization stage) but not central attention. The implications of the results are discussed.     

From a fixation on sports to an exploration of mechanism: The past,present, and future of hot hand research

We review the literature on the hot hand fallacy by highlighting the positive and negative aspects of hot hand research over the past 20 years, and suggesting new avenues of research. Many researchers have focused on criticising Gilovich et al.'s claim that the hot hand fallacy exists in basketball and other sports, instead of exploring the general implications of the hot hand fallacy for human cognition and probabilistic reasoning. Noting that researchers have shown that people perceive hot streaks in a gambling domain in which systematic streaks cannot possibly exist, we suggest that researchers have paid too much attention to investigating the independence of outcomes in various sporting domains. Instead, we advocate a domain-general mechanistic approach to understanding the hot hand fallacy, and conclude by suggesting approaches that might refocus the literature on the important general implications of the hot hand fallacy for human probabilistic reasoning.     

Transitivity for height versus speed: To what extent do the under-7s really have a transitive capacity?

Transitive inference underpins many human reasoning competencies. The dominant task (the “extensive training paradigm”) employs many items and large amounts of training, instilling an ordered series in the reasoner's mind. But findings from an alternative “three-term paradigm” suggest transitivity is not present until 7 + years. Interestingly, a second alternative paradigm (the “spatial task”), using simultaneously displayed height relationships to form premise pairs, can uphold the 4-year estimate. However, this paradigm risks cueing children and hence is problematic. We investigated whether a height-task variant might correspond to a more ecologically valid three-term task. A total of 222 4–6-year-olds either completed a modified height task, including an increased familiarisation phase, or a computer-animated task about cartoon characters running a race in pairs. Findings confirmed that both tasks were functionally identical. Crucially, 4-year-olds were at chance on both, whereas 6-year-olds performed competently. These findings contrast with estimates from all three paradigms considered. A theoretical evaluation of our tasks and procedures against previous ones, leads us to two conclusions. First, our estimate slightly amends the 7-year estimate offered by the three-term paradigm, with the difference explained in terms of its greater relevance to child experiences. Second, our estimate can coexist alongside the 4-year estimate from the extensive training paradigm. This is because, applying a recently developed “dual-process” conception of reasoning, anticipates that extensive training benefits a species-general associative system, while the spatial paradigm and three-term paradigm can potentially index a genuinely deductive system, which has always been the target of transitive research.     

Executive functions in decision making: An individual differences approach

This individual differences study examined the relationships between three executive functions (updating, shifting, and inhibition), measured as latent variables, and performance on two cognitively demanding subtests of the Adult Decision Making Competence battery: Applying Decision Rules and Consistency in Risk Perception. Structural equation modelling showed that executive functions contribute differentially to performance in these two tasks, with Applying Decision Rules being mainly related to inhibition and Consistency in Risk Perception mainly associated to shifting. The results suggest that the successful application of decision rules requires the capacity to selectively focus attention and inhibit irrelevant (or no more relevant) stimuli. They also suggest that consistency in risk perception depends on the ability to shift between judgement contexts.     

Culture,religion, and the underlying value dimensions of the metapersonal self-construal

The metapersonal self-construal (MPS) is presented in the context of a three-factor model of self-construal that is grounded in the literature on culture and values. The MPS is an understanding of the self as profoundly interconnected with all humanity and nature. It is distinct from the independent and interdependent self-construals and may emerge from one's cultural, religious, or spiritual background. Relating self-construal with a structural model of values, Study 1 indicated that while the independent and interdependent self-construals marked each end of a continuum, the MPS was associated with a unique cluster of values centred around universalism. Studies 2 and 3 found support for the predicted effects of membership in Buddhist groups and identification with Aboriginal culture on MPS. These results support the MPS as a unique understanding of the self that reflects surrounding beliefs and values. Implications for understanding the relationship between spirituality and well-being are discussed.     

Intersecting cultural identities and help-seeking attitudes: the role of religious commitment,gender, and self-stigma of seeking help

ABSTRACT

The current study (N?=?404) used a moderated moderation model to examine how gender, religious commitment, and self-stigma toward seeking psychological help may interact in the prediction of help-seeking attitudes. Bivariate zero-order correlations indicated that help-seeking attitudes was negatively associated with self-stigma of seeking help (r?=??.55) and positively associated with religious commitment (r?=?.14), and self-stigma was not significantly associated with religious commitment. Men reported more negative attitudes than women (ΔM?=??.18). Furthermore, multiple regression results revealed a three-way interaction such that the relationship between gender and help-seeking attitudes was moderated by both self-stigma and religious commitment. Specifically, men with high religious commitment and high self-stigma endorsed the most negative help-seeking attitudes, suggesting that religious men’s help-seeking attitudes may be particularly susceptible to the influence of self-stigma. Implications for research and the development of targeted interventions are discussed.
