MENTAL HEALTH OF TRAUMA-EXPOSED FIREFIGHTERS AND CRITICAL INCIDENT STRESS DEBRIEFING

Interest in critical incident stress debriefings for firefighters has grown over the last decade. Some researchers report that debriefings protect firefighters from stress-related disorders, including posttraumatic stress disorder (PTSD). Proponents of the interventions claim extraordinary need and success. Controlled and correlational studies have largely failed to demonstrate therapeutic effects, and some report iatrogenic effects. This study examined the relationships between debriefings and several mental health variables in a large sample of firefighters. Debriefing had a weak inverse correlation with negative affectivity and a weak positive correlation with positive world assumptions. No relationship was found between debriefing and PTSD.     

Object and action picture naming in English and Greek

When two orthographically similar words are displayed using rapid serial visual presentation (RSVP), the repeated letters in the second critical word (W2) are not detected, leading to a deficit in reporting this word known as repetition blindness (RB). In Turkish, letters containing diacritic markings (e.g., y, ö) are considered separate letters, yet are visually highly similar to their non-diacritic analogues (s,o). Two experiments used the phenomenon of RB to investigate whether diacritic letters are represented as more similar to their non-diacritic analogues than are two unrelated letters. In Experiment 1, substantially more RB was found for words differing in just a diacritic (i y im-isim) compared to orthographic neighbours (words differing in a visually non-similar letter, such as ilim-isim). In Experiment 2, the amount of RB for identical words (isim-isim) was comparable to words that differed by a single diacritic marking (i y im-isim). We conclude that diacritic letters are mentally represented as variants of their non-diacritic analogue. Letter / word recognition researchers may be interested in pursuing these findings using standard techniques such as backward masking and orthographic priming.     

Probabilistic numerical discrimination in mice

Previous studies showed that both human and non-human animals can discriminate between different quantities (i.e., time intervals, numerosities) with a limited level of precision due to their endogenous/representational uncertainty. In addition, other studies have shown that subjects can modulate their temporal categorization responses adaptively by incorporating information gathered regarding probabilistic contingencies into their time-based decisions. Despite the psychophysical similarities between the interval timing and nonverbal counting functions, the sensitivity of count-based decisions to probabilistic information remains an unanswered question. In the current study, we investigated whether exogenous probabilistic information can be integrated into numerosity-based judgments by mice. In the task employed in this study, reward was presented either after few (i.e., 10) or many (i.e., 20) lever presses, the last of which had to be emitted on the lever associated with the corresponding trial type. In order to investigate the effect of probabilistic information on performance in this task, we manipulated the relative frequency of different trial types across different experimental conditions. We evaluated the behavioral performance of the animals under models that differed in terms of their assumptions regarding the cost of responding (e.g., logarithmically increasing vs. no response cost). Our results showed for the first time that mice could adaptively modulate their count-based decisions based on the experienced probabilistic contingencies in directions predicted by optimality.     

Chronic Childhood Peer Rejection is Associated with Heightened Neural Responses to Social Exclusion During Adolescence

This functional Magnetic Resonance Imaging (fMRI) study examined subjective and neural responses to social exclusion in adolescents (age 12–15) who either had a stable accepted (n?=?27; 14 males) or a chronic rejected (n?=?19; 12 males) status among peers from age 6 to 12. Both groups of adolescents reported similar increases in distress after being excluded in a virtual ball-tossing game (Cyberball), but adolescents with a history of chronic peer rejection showed higher activity in brain regions previously linked to the detection of, and the distress caused by, social exclusion. Specifically, compared with stably accepted adolescents, chronically rejected adolescents displayed: 1) higher activity in the dorsal anterior cingulate cortex (dACC) during social exclusion and 2) higher activity in the dACC and anterior prefrontal cortex when they were incidentally excluded in a social interaction in which they were overall included. These findings demonstrate that chronic childhood peer rejection is associated with heightened neural responses to social exclusion during adolescence, which has implications for understanding the processes through which peer rejection may lead to adverse effects on mental health over time.     

Quantitative Empirical Studies on Women’s Issues in Islamic Cultures: Introduction to Special Issue

The special issue aimed to focus on quantitative research articles covering gender and women’s issues in Islamic cultures which have not received sufficient attention. The present issue of gender and women’s issues in these cultures adds important information about topics such as the roles of honor, religiosity, and sexism as they interact with gender. In the special issue there are six quantitative research articles focusing on various topics relevant to honor, sexism, economic, and health issues. A study from Turkey examines the associations among benevolent sexism, hostile sexism, religiosity, and the endorsement of honor beliefs in Turkey. Another explores the effects of religious affiliation, patriarchy, and gender on the perception of honor-related crimes in Morocco, Cameroon, and Italy. Views about family issues are explored in a paper from North Cyprus that explores the associations among hostile sexism, benevolent sexism, religiosity, and attitudes toward childlessness. In another paper, researchers from Turkey investigate job-relevant gender issues such as work engagement, job insecurity, and turnover intentions. Finally, women’s health in Muslim cultures is the focus of papers on health screening behaviors in Turkey and on factors relevant to menopausal symptoms of women in Pakistan. In the introduction, the main purposes of the special issue articles are introduced. Then, the importance of studying honor, sexism, religiosity, the economic situation of women, and women’s health issues in Islamic cultures are covered. Some suggestions for future studies and implication and applications of the research findings also are discussed. Finally, limitations of the special issue are presented.     

Exploring Factors Associated with Psychological Resilience Among Earthquake Survivors from Turkey

This study aimed to explore factors associated with psychological resilience in a sample of 360 survivors of the two earthquakes in Van, Turkey in 2011. Using a survey with measures on various pre-, within-, and post-disaster variables, it has been shown that psychological resilience was influenced by multiple factors, providing empirical evidence for a multifactorial understanding of resilience. Furthermore, the study extended the traditional ways of resilience assessment by including stress-coping ability and severity of trauma-related symptoms as indicators of psychological resilience simultaneously. Findings were discussed considering the implications for research and interventions in the aftermath of natural disasters.     

Disentangling proactive and reactive aggression in children using self-report

The distinction between proactive and reactive functions of aggression is one of the most common divisions when investigating aggression among children and adolescents. To date, self-report is the least used measurement, despite existing literature supporting the view that the best informant regarding internal processes and motives are children themselves. The main aim of this study was to examine the construct and concurrent validity of a new self-report questionnaire, which aims to disentangle acts of reactive vs. proactive aggression that are most common within the daily lives of children. We examined the self-report measure among 578 children (313 girls, 265 boys, mean age 11 years, range 9–13 years). Most children (90% boys; 85% girls) reported at least one act of aggression over the last four weeks. Furthermore, the outcomes support the two-factor structure (reactive and proactive aggression) and the questionnaire showed good concurrent and discriminant validity with measures for emotional and social functioning. This study validates the use of the self-report instrument for reactive and proactive aggression and demonstrates that children can successfully distinguish between their own motives for reactive and proactive forms of aggressive behaviours.     

Burnout and occupational participation among dentists with teaching responsibilities in universities

The aim of this study was to investigate the levels of burnout and explore the relationships between burnout and occupational participation among dentists with teaching responsibilities. Canadian Occupational Performance Measure (COPM) was used to evaluate occupational participation with questions on demographic information among 155 dentists with teaching responsibilities. Age, gender, years of experience, academic position were the factors affecting level of burnout and occupational participation. Occupational performance score was negatively correlated with emotional exhausment (r = –.731) and depersonalization (r = –.693) while positively correlated with personal accomplishment (r = .611). Occupational satisfaction scores were negatively correlated with emotional exhausment (r = –.631) and depersonalization (r = –.625) while positively correlated with personal accomplishment (r = .614). Occupational participation level can effect burnout among dentists with teaching responsibilities. Further studies with a larger sample are needed to investigate these preliminary results deeply.     

The Effects of Alcohol Intoxication on Accuracy and the Confidence–Accuracy Relationship in Photographic Simultaneous Line‐ups

Acute alcohol intoxication during encoding can impair subsequent identification accuracy, but results across studies have been inconsistent, with studies often finding no effect. Little is also known about how alcohol intoxication affects the identification confidence–accuracy relationship. We randomly assigned women (N = 153) to consume alcohol (dosed to achieve a 0.08% blood alcohol content) or tonic water, controlling for alcohol expectancy. Women then participated in an interactive hypothetical sexual assault scenario and, 24 hours or 7 days later, attempted to identify the assailant from a perpetrator present or a perpetrator absent simultaneous line‐up and reported their decision confidence. Overall, levels of identification accuracy were similar across the alcohol and tonic water groups. However, women who had consumed tonic water as opposed to alcohol identified the assailant with higher confidence on average. Further, calibration analyses suggested that confidence is predictive of accuracy regardless of alcohol consumption. The theoretical and applied implications of our results are discussed.© 2017 The Authors Applied Cognitive Psychology Published by John Wiley & Sons Ltd.
