Reaction time to threat stimuli in panic disorder and social phobia

Two studies assessed response time among clinically anxious subjects and normal controls when presented with threat, positive and neutral stimuli under perceptual (lexical decision) and semantic (category decision) task conditions. In Study 1, panic disorder subjects' (n = 14) performance was compared to that of matched normal controls (n = 14) while in Study 2 social phobic subjects (n = 24) were compared to matched normal controls (n = 24). Relative to matched normal controls, panic disorder subjects but not social phobics tended to show greater slowing in performance on the more cognitively complex (category) task. A second finding, consistent across both studies was that, compared to the normal control groups, both panic and social phobic groups showed significantly slowed responses to threat words in both the perceptual and semantic tasks. Such findings are directly counter to the predictions of a mood congruence hypothesis. This apparent contradiction is resolved by a review of the literature which indicates that mood-related facilitation effects are obtained only in tasks which tap awareness of threat information rather than speed of response. It is suggested that while anxiety may produce enhanced awareness of threat, it may inhibit responsiveness to it. The results of these studies are seen as consistent with ethological theories of inhibited motoric responses under certain threat conditions. Furthermore, the findings suggest that caution is indicated in interpreting slowed reaction time to threat stimuli in tasks such as the Stroop color naming task as purely the result of attentional processes.     

Pursuing Academic Interests: The Role of Implicit Theories

Students can believe that their academic interests are fixed (entity theory) or malleable (incremental theory). A measure of implicit theories of academic interests was developed to examine how such theories influence students' decisions to retain or change their majors. As hypothesized, entity theorists who believed that they were not doing well in their majors were more likely to choose a new major than were all other groups. This result is consistent with previous findings that entity theorists tend to give up in the face of adversity.     

Should We Agree to Disagree? The Multilevel Moderated Relationship Between Safety Climate Strength And Individual Safety Motivation

Organisational research investigating climate perceptions often use constructs reflecting dispersion and disagreement, termed ‘climate strength’, to investigate situational pressures on behaviour expression. Within safety-specific contexts, research has tended to emphasise the prediction of climate strength rather than an examination of its effects on behaviour. The present paper investigates the important first pathway in the prediction of safety behaviour by investigating the influence of safety climate strength on the relationship between safety climate perceptions and individual safety motivation in a safety critical context using multilevel analyses. Contrary to expectations, results initially indicated that safety climate strength negatively influenced the relationship between safety climate perceptions and safety motivation, such that greater variability was associated with greater motivation. Post hoc analysis re-grouping responses into broader functional levels found support for an interaction, suggesting a difference in the scope of influence for safety climate strength between the two levels of analysis. These findings are discussed in light of self-determination theory, and suggestions for future research and practice made.

     

Brief Report: Symptoms of PTSD,Coping Strategies,and Social Adjustment among Survivors of Early Life Interpersonal Trauma

Dysphoria symptoms of posttraumatic stress disorder (PTSD) have been associated with impairments in social functioning; however, this relationship has been unexamined among interpersonal trauma populations. A sample of 303 women with a history of early life interpersonal trauma completed measures of PTSD severity, coping, and social functioning. Results revealed that dysphoria symptoms had a strong and unique association with total social adjustment and social functioning (i.e., social activities). Active coping significantly mediated the relationship between dysphoria symptoms and total social adjustment, and active coping and seeking emotional support significantly mediated the relationship between dysphoria symptoms and social functioning. Findings elucidate variants of coping that might compound impaired social functioning and highlight the value of integrating coping skills into PTSD interventions.     

What individuals believe they can and cannot do: explorations of realistic and unrealistic control beliefs

We examined construct validity and implications of scales that assess perceived control over controllable events (realistic control belief) and perceived control over uncontrollable events (unrealistic control belief). We found that people high in unrealistic control belief are less likely to discriminate between controllable and uncontrollable situations and to distort task outcomes so as to make them appear more favorable (more under control). We also found that people high in realistic control belief are more likely to assume responsibility for past mistakes. In additional studies on coping and health risk behavior, higher realistic control belief was related to direct engagement with the stressor and to less risky sexual behavior; higher unrealistic control belief was related to less emotional processing and to more risky sexual behavior. The results demonstrate a need to discriminate between the two types of control beliefs.

Family business: A fertile ground for research on time,teams and positive organizational study

Further reflecting on the study of organizational behaviour (OB) in family business (FB), this rejoinder piece discusses and integrates the points raised in the three thoughtful commentaries and our original article. We start by highlighting the general agreement between us and the commentators on three points: (1) that family firms are theoretically distinct from non-family firms due to significant involvement of kinship ties in the enterprise; (2) there is paucity of research at the interface of OB and FB and (3) there is an abundance of interesting research questions at this interface with the potential to benefit both domains of study. Next, we discuss and elaborate on the research possibilities on time, teams and positive organizational study, suggested by the commentators. An illustrative list of interesting research questions at the OB–FB interface that extend and enrich our agenda for future research is shared. We conclude that not only is FB a promising context for behavioural scholars to investigate, the timing is perfect for such investigations.     

Peritraumatic dissociation and PTSD severity: do event-related fears about death and control mediate their relation?

Relations among peritraumatic dissociation, PTSD severity, event-related fear (i.e. fear experienced during traumatic event) about death, and event-related fear about losing control were examined in the current study. Particular emphasis was placed on testing whether or not fears about death and losing control mediate the relation between peritraumatic dissociation and PTSD severity in a sample of 146 nontreatment-seeking university women. Results indicated that event-related fears about death and losing control accounted for the relation between peritraumatic dissociation and PTSD severity; that is, the effect of peritraumatic dissociation on PTSD severity was eliminated after controlling for these fears. Speculations about findings are discussed.     

To Follow Expert Advice When Making a Decision: An Examination of Reactive Versus Reflective Autonomy

The present study examined whether reactive and reflective autonomy moderated individuals' responses to expert influence. Participants were given the opportunity to win money at a racetrack betting task for which they were provided with objective information about horses' previous performances along with specific expert recommendations. The experts were made to look either credible or noncredible by manipulating information on the success rate of their previous predictions. The results showed that the two forms of autonomy led to exactly opposite behaviors in response to the advice of credible experts. Reflective autonomy was significantly positively associated with following the recommendations of credible experts whereas reactive autonomy was significantly negatively associated with following the recommendations. The results also showed that it was particularly after losing their first race that reactive autonomy was related to rejecting the advice of experts. These findings indicate that reactive and reflective forms of autonomy may yield opposite patterns of behavior in certain situations.
