The effects of exposure to an acute naturalistic stressor on working memory, state anxiety and salivary cortisol concentrations

Exposure to an acute naturalistic stressor induces both psychological and physiological changes in humans. The two studies reported here explored the impact of exposure to an acute naturalistic stressor on state anxiety, working memory and HPA axis activation (salivary cortisol). In both experiments, ten healthy male participants were exposed to an acute naturalistic stressor, helicopter underwater evacuation training (HUET), and their physiological and behavioural responses before (first study) and after (second study) the stressor were compared to ten non-stressed controls. The results of both experiments showed that working memory performance was preserved during anticipation of an acute stressor, but impairments were observed immediately after stress exposure. Participants reported significantly higher state anxiety levels during anticipation and following stress exposure, whereas significant elevations in cortisol levels were only observed 25 min post exposure to stress, but not before or immediately after stress exposure. The results of both experiments demonstrated a dissociation between behavioural and biochemical measures and provided evidence for a dissociation of the effects of stress on cognitive and physiological measures depending on the time of testing, with cognitive impairments most evident following stress exposure.     

Perceived Meeting Effectiveness: The Role of Design Characteristics

Purpose  The aim of this investigation was to test hypotheses about meeting design characteristics (punctuality, chairperson, etc.) in relation to attendees’ perceptions of meeting effectiveness. Design/Methodology/Approach  Two studies were conducted: Study 1 investigated meetings attended in a typical week (N = 958), whereas Study 2 examined the last meeting attended on a particular day (N = 292). Findings   A number of design characteristics (in particular agenda use and quality of facilities) were found to be important in predicting perceived effectiveness. Attendee involvement served as a key mediator variable in the observed relationships. Neither meeting type nor size was found to affect the relationships of the design characteristics and involvement with effectiveness. Meeting size, however, was negatively related to attendee involvement. Implications  The findings help us to better understand relationships between design characteristics and attendees’ perceptions of meeting effectiveness. Meeting organizers can use the findings to guide administration of meetings, with potential to enhance the quality of meetings. Originality/Value   Meetings are a common organizational activity but are rarely the focus of empirical research. The use of two complementary studies, to our knowledge, provides a unique account of the contribution of design characteristics to perceptions of meeting effectiveness.

Perception of Easy–Difficult: Attitude or Self‐Efficacy?

This study investigates the semantic-differential item easy-difficult in order to evaluate whether it can be considered a measure of attitude or self-efficacy in relation to consistent condom use with sex partners. Using confirmatory factor analysis and comparing a set of logically nested models, our findings suggest that easy-difficult acts most like an attitude item in relation to this particular behavior, especially for males rating condom use with their main sex partners. However, for females and to a less extent males with nonmain sex partners, easy-difficult acts as a measure of both attitude and self-efficacy. Therefore, the use of easy-difficult items should be avoided or used with caution in this research context.     

The link between time orientation and religious orientation among American college students

The purpose of this study was to explore how an individual’s religion relates to their time orientation. Specifically, we hypothesised (a) intrinsic orientation would positively correlate with future orientation, (b) extrinsic orientation would positively correlate with present-hedonistic orientation, (c) quest orientation would positively correlate with present-hedonistic and future orientations, (d) orthodox orientation would positively correlate with past positive orientation, and (e) secularism would positively correlate with past negative orientation, present-fatalistic and future orientations. Participants (n?=?150) completed an online survey of time orientation and religious orientation. The results showed that perceptions of the past are strongly linked to religious orientation, with more positive perceptions being linked to the more traditional orientations, and less positive perceptions linked to the looser and secularist orientations.     

Aging and response inhibition: Normative data for the Victoria Stroop Test

Increased difficulty with response inhibition occurs with age, although there is some controversy as to whether increased interference on Stroop tasks reflects difficulties with response inhibition or simply reflects generalized cognitive slowing. The Victoria Stroop Test (VST) is a brief, easily administered, psychometrically sound version of Stroop's original task. Performance on the VST by adults across a wide age span was examined to determine the association between age and various measures of interference. In addition, normative data for the VST were calculated. Participants were 272 healthy, community-dwelling adults age 18 to 94. Age and speed were negatively correlated on all trials of the VST. Importantly, however, interference scores that were corrected for baseline slowing remained highly correlated with age. Similarly, age and error scores on the interference trial were positively correlated, indicating decreased accuracy with age. These findings suggest that increased interference on Stroop tasks with age is not accounted for by simple cognitive slowing and more likely reflects other cognitive changes, such as decreased response inhibition. The VST has a number of administrative and psychometric strengths, and the provision of normative data should enhance its potential for clinical and research applications.     

Less is more: executive function and symbolic representation in preschool children

Executive function is recognized as a critical component of children's cognitive and social development. In two studies, a measure of executive function that had been used in research with chimpanzees was adapted for preschoolers. On this task, called Less Is More, children must point to a smaller reward (two candies) to receive a larger reward (five candies). In Study 1 (N= 101), performance was significantly related to age (3 vs. 4), verbal ability, and established measures of executive function. In Study 2 (N= 128), symbolic representations substituted for real candies in this task. Three-year-olds' performance improved significantly as a function of symbolic distancing. This research has implications for the role of symbol systems in the development of executive control over thought and action.     

The Value of Strength-Based Approaches in SERE and Sport Psychology

During the past 2 decades, the psychosocial landscapes of the military and elite sport have drastically changed, with the presence of stress an increasing health and safety concern. For example, in modern warfare, fighters must have the psychological capabilities to counter terrorism and undertake extended deployments in extreme environments against enemies with increasing skills for rapid development and dissemination of information and weaponry via global communication networks. In sport, performers have also reported being affected by globalization, reporting a hazardous array of stressors (e.g., roles, relationships, development issues, and organizational structure and climate) associated with preparation for and performance at major international competitions. The result of such developments is the need for leaders in both the military and sport to better understand optimal performance, and in particular the preparation of their charges, the war fighter and athlete, for the demands of their respective competition arenas. Therefore, in this narrative review we identify strength-based concepts of common interest and potential knowledge transfer in the study of psychology of excellence in the face of adversity between sport and military domains. Specifically, we highlight a value of 6 strength-based concepts for elite performance environments in sport (i.e., Olympic performance) and the military (Survival, Evasion, Resistance, and Extraction: SERE); mental toughness, positive emotion, learned optimism, resilience, posttraumatic growth, and self- and emotion regulation. In line with this discussion we highlight commonalities and knowledge transfer considerations regarding interventions in these spheres of psychological practice, the potential value of humanism and existentialism, the importance of post career and rehabilitation intervention, and readiness to change and engagement in training.     

How do Physicians Decide to Refer Their Patients for Psychiatric Genetic Counseling? A Qualitative Study of Physicians’ Practice

Psychiatric genetic counseling (PGC) is an emerging specialty discipline within the genetic counseling profession. A specialist PGC service was founded in 2012 in Vancouver, Canada, and though patient benefits have been demonstrated, many physicians do not regularly refer patients to the service despite awareness of its availability. We conducted a qualitative study involving semi-structured telephone interviews with Vancouver-based physicians who were aware of the PGC service to explore this phenomenon. Interviews were audio-recorded, transcribed verbatim, coded, and analysed for emergent themes. Consistent with a grounded theory approach, constant comparison was employed throughout data collection and analysis. Analyses of interviews conducted with 12 physicians revealed that referral practices were informed by perceptions about the purpose of PGC and interpretation of patient cues. Physicians perceived PGC as an information-focused intervention, and considered referral when patients explicitly expressed desire for information about recurrence risk or etiology that they felt unable to adequately address themselves. Even when physicians identified psychotherapeutic benefits of PGC, patient needs of this nature were not perceived as cues prompting referral to PGC. These data suggest that further work is necessary to position PGC in physicians’ minds as a service that could potentially benefit most individuals with psychiatric disorders and their families, and that it encompasses more than information provision. It is important to increase physicians’ awareness of the complementary role that genetic counselors can play to that of the physician in providing psychotherapeutically oriented counselling about illness etiology.
