Resting autonomic activity in adults who stutter and its association with self-reports of social anxiety

PurposeThe purpose of this study was to investigate resting autonomic activity in adults who stutter (AWS) compared to adults who do not stutter (ANS) and the relationship this has on self-reports of social anxiety.MethodsThirteen AWS and 15 ANS completed the Social Interaction Anxiety Scale (SIAS; Mattick & Clark, 1998) and Brief Fear of Negative Evaluation (BFNE; Leary, 1983). Following this, measures of skin conductance levels (i.e. index of sympathetic activity) and respiratory sinus arrhythmia (i.e. index of parasympathetic activity) were taken during a 5-minute resting, baseline period. Independent sample t tests were used to assess differences between groups on self-reports of anxiety (SIAS, BFNE) and resting autonomic levels (SCL, RSA). Separate multiple regression analyses were performed in order to assess the relationship between self-reports of anxiety and autonomic measures.ResultsResults showed significantly higher mean SCL and lower mean RSA levels in the AWS compared to the ANS at resting, baseline. Regression analysis showed that self-reports from the SIAS had a significant effect on RSA levels for the AWS but not the ANS. No significant effects were found for BFNE on RSA. Nor was there a significant effect from SIAS or BFNE on SCL levels for either group.ConclusionFindings suggest that resting RSA levels may be a physiological marker for social anxiety levels in adults who stutter.     

Sexual activity while driving: A content analysis of media reports

Sexual activity while driving fits the definition of distracted driving because it involves the diversion of attention away from the driving task. However, this risky driving behaviour has received little attention compared to other distracted driving activities. To address the lack of research on sexual activity while driving, the internet was searched from April to June 2020 for media reports in which sexual activities occurred within the cabin of a moving vehicle, taking specific note of: gender, the presence of others, time of day, use of substances, the nature of the circumstances surrounding the incident, and whether crashes had occurred. A total of 106 unique and verified cases were identified from 2004 to 2020. The reports involved 76 male (71.7%) and 30 female drivers (28.3%), and there were 43 (40.5%) serious incidents that involved a crash and 23 fatalities (21.7%). In 17 (16.0%) incidents their vehicle hit another car, and a pedestrian or cyclist was hit in 3 (2.8%) incidents. The risk of a serious incident was higher during oral sex or intercourse than solitary activities (i.e. masturbation). A total of 63 (59.5%) mild incidents (without crashes or fatalities) were identified, in which reports included accounts by witnesses or police regarding sexual activity while driving. Given the potential seriousness of incidents, this topic deserves further research to better understand the prevalence and safety implications of sexual activity while driving.     

Safety of micro-mobility: Riders’ psychological factors and risky behaviors of cargo TTWs in China

Cargo two- or three-wheeled vehicles (TTWs), as a new form of micro-mobility, have become a popular mode of urban cargo transportation in China. Cargo TTW riders’ psychological factors and risky behaviors lead to a number of accidents. A questionnaire is designed by comprehensively considering these factors and behaviors of cargo TTW riders that includes eleven risk factors to quantitatively analyze the risky behaviors based on structural equation modeling (SEM). One thousand three hundred nineteen participants reported using cargo TTWs on a questionnaire distributed across the country. The characteristics of riding behavior data are analyzed to verify the three-layer risk theoretical framework of “Psychological factors (Personality traits/specific factors) - Psychological acceptability of risks (confidence/perception/attitude) - Risky behaviors”. The results show that anger has a strong direct effect on riding violations, while normlessness and altruism have a direct effect on riding errors. Workload has a weak but direct effect on risky behaviors, and riding feedback has a weak and mixed effect. In addition, high-risk groups are identified by analysis of variance (ANOVA) with rider population attributes. These quantitative analyses can help guide safety countermeasures to mitigate accidents involving cargo TTWs.     

Dynamiques représentationnelles et identitaires au cours de la socialisation professionnelle de jeunes recrues LGBT

This article examines the ways in which representational and identity transformations work during the socialization in the workplace of young LGBT hires, linked to discrimination perceived in their workplace environment as well as their impact on professional goals. Working within the theoretical framework of active socialization, the study is based on the IMIS method and proposes a detailed analysis of two cases recently entering the transportation workplace. The results show that, depending on how severe the perceived discrimination is in the workplace, previous experiences of homophobia encountered in other environments and already built self-image are reactivated in different ways, leading to a more or less important reconstruction of professional and identity representations, as well as the future goals of the individual. These elements are discussed from the point of view of interactions between environments and possible interventions by valuing diversity and accompanying the integration of young hires into organizations.     

Exercise is medicine… when you enjoy it: Exercise enjoyment,relapse prevention efficacy,and health outcomes for youth within a drug and alcohol treatment service

ObjectiveEvidence for the effectiveness of exercise as therapy for youth substance use disorder (SUD) is scarce. In this study, we investigated associations between exercise enjoyment and recovery outcomes for youth undergoing residential SUD treatment.MethodUsing ecological momentary assessment, each week participants reported perceptions of exercise enjoyment, relapse prevention efficacy, self-esteem, and physical health, and associations between these variables were assessed at both between- and within-person levels. There were 97 participants (age: M = 17.5, SD = 1.57, range = 14 to 21; 37 female, 60 male), with a final sample of 64 due to participants (n = 33) discontinuing treatment within 2 weeks of commencement. Of the remaining sample, 50% (n = 32) completed 3 or more assessments, 40% (n = 26) completed 5 or more, and 25% (n = 16) completed 7 or more.ResultsRelapse prevention efficacy, self-esteem, and perceived physical health increased over time in the program. Youth who, on average, enjoyed exercise more had higher self-esteem, perceived physical health, and relapse prevention efficacy than those who enjoyed it less. Additionally, on occasions when youth enjoyed exercise more (relative to their own average), they reported higher self-esteem, perceived physical health, and relapse prevention efficacy than on occasions when they reported enjoying it less.ConclusionParticipation in—and importantly, enjoyment of—exercise was linked to key health indices and predictors of relapse for youth during SUD treatment. These findings demonstrate that participation in enjoyable structured exercise may provide an important component of successful SUD treatment.     

Social identity leadership in sport and exercise: Current status and future directions

The social identity approach is fast becoming a prominent framework for understanding effective leadership in sport and exercise contexts. The last five years, in particular, has seen a proliferation of research informed by the identity leadership approach, with a focus on two broad outcomes: performance and health. Using these two key outcomes as an organising framework, we provide a critical narrative review of research that has examined the presence, role, and benefits of identity leadership in sport and exercise contexts, and identify fruitful avenues for future research. Applying a broader lens, we then make five key recommendations for future identity leadership research in sport and exercise contexts. Specifically, we highlight the need for research (a) using more rigorous and varied research designs, (b) using stronger measures, (c) comparing the effects of identity leadership to the effects of other types of leadership, (d) assessing further potential mediators of relationships between identity leadership and key outcomes, and (e) exploring the possible dark side of identity leadership.     

Sexual jealousy in young women and men: Aggressive responsiveness to partner and rival

Two studies compared judgments about aggressive components of jealous reactions to the partner and to the rival, specifically, emotional (anger), cognitive (blame), and behavioral components. The first study randomly assigned 172 young women and men to two questionnaires on jealous reactions to mild (flirting) and serious (cheating) transgressions. One questionnaire assessed standards for appropriate behavior and perceptions of how people usually react. The second questionnaire asked people to report how they had reacted or, if not experienced with a sexual transgression, how they would react. The second study asked 113 people to imagine a situation in which they knew their partner had been sexually unfaithful. There were three major findings that were interpreted in the context of courtship, a time when attention is focused on the qualities of one's potential long-term partner. First, the jealous individual's anger and blame were focused more on the partner than the rival. Second, mean anger and blame scores given the partner were well matched. In contrast, the rival received more anger and blame than deemed appropriate and considerably more anger than blame. These data suggest that, in the context of courtship, a rival is not simply a competitor. Third, men were more inclined to think about aggressive action against the rival but women were more emotionally and behaviorally reactive to the rival. The latter result implies that, in the context of competition for an established romantic partner, a rival is more salient for women than for men. © 1993 Wiley-Liss, Inc.     

Aggressive behavioral characteristics,hormones, and sexual orientation in men and women

Aggressive behavioral characteristics were assessed in groups of men and women by a self-report instrument, the Aggression Inventory, in which adult males reported more physical and verbal aggression than did females. Furthermore, males had higher scores on measures of impulsiveness and lack of frustration tolerance than did females, while women were more likely to avoid confrontation. In a second study, groups of male and female homosexuals and heterosexuals completed this Aggression Inventory after having blood samples taken to assay resting levels of testosterone (T) and estradiol (E). Groups of subjects within each gender were closely matched in terms of age, education, and vocational interests. Women were matched for the same time in their menstrual cycle (early follicular phase). Among men, homosexuals were indistinguishable from heterosexuals on all measures of aggression. Lesbians did not differ from heterosexual women on any aggression subscale except physical aggression, in which the homosexual women had lower scores. T and E were positively correlated with several indices of aggressive behavioral characteristics in men but were negatively correlated with those same measures in women.     

Fighting experiences and natural killer cell activity in male laboratory mice

There is currently much interest in the potential impact of psychological factors on immune responses. An attempt was made to assess the effects of dominant/subordinate polarity in male mice on the cytotoxic activities of their natural-killer (NK) cells. On the basis of repeated agonistic encounters, categories of subordinate and dominat animals were selected. These animals were compared with manipulated controls (introduced to a novel test cage without an opponent on each occasion) and undisturbed controls (who remained in isolation without manipulation). In terms of NK activity, immunosuppression was observed in both dominant and subordinate categories when compared to undisturbed controls. There were, however, no differences between the fighting exposed subjects and the manipulated controls, suggesting that stress accounts for any changes. © 1994 Wiley-Liss, Inc.     

Influence of timing of post-weaning isolation on play fighting and serious aggression in the male golden hamster (Mesocricetus auratus)

Effects of timing of social isolation on play fighting and serious fighting were studied at different ages in male golden hamsters. Litters were isolated at 21, 35, and 65 days of age, and tested in a resident-intruder paradigm. Behaviors were compared within grous and with a fourth group of socially reared conspecifics. The earlier the pups were isolated, the more they engaged in play activities. Later, in adulthood, the aggression level of the same animals was retested using the same paradigm. The three isolated groups showed a high level of aggression, with significant differences among them. When compared with socially reared subjects, a reliable difference in the level of aggression was also found. These results support the view that early social experience is important, suggesting that isolation during early critical periods of socialization has a significant impact on play fighting, whereas short periods of isolation may be enough to trigger adult agonistic behavior. © 1994 Wiley-Liss, Inc.
