Muscularity Beliefs of Female College Student-Athletes

Female athletes in the United States face the paradoxical challenge of acquiring a degree of muscularity to be successful in their sport, yet they also endure pressure from societal expectations of femininity that often don??t conform with the notion of muscularity. To address research questions about how female student-athletes balance muscularity and femininity, we conducted a mixed-methods study to examine muscularity beliefs among female student-athletes, female college students, and male college student-athletes. We quantitatively examined Drive for Muscularity Scale (DMS) scores from 221 participants attending college in the Midwestern US. Results indicated that female student-athletes reported significantly higher DMS scores than female students, but male student-athletes reported the highest DMS scores in the sample. Qualitative results indicated that female student-athletes wanted to be muscular for these reasons: functionality (45%), health (42%), external gratification (21%), and internal gratification (18%). Only 16% of female student-athletes did not want to be muscular, whereas every male student-athlete reported a desire to be muscular. The results of this study can be used to better understand the unique drive for muscularity among athletes, particularly female college student-athletes who live the paradox of negotiating societal standards of femininity with this desire to be muscular. This enhanced understanding can help create more nuanced interventions for coaches, administrators, and mental health professionals to use to help female student-athletes create space to resist constraining societal gender ideologies. Doing so can help these student-athletes actualize their athletic potential on the field as well as their interpersonal and intrapersonal potential off the field.     

On people’s understanding of the diagnostic implications of probabilistic data

Two lines of prior research into the conditions under which people seek information are examined in light of two statistical definitions of diagnosticity. Five experiments are reported. In two, subjects selected information in order to test a hypothesis. In the remaining three, they selected information in order to convince someone else of the truth of a known hypothesis. A total of 567 university students served as subjects. The two primary conclusions were as follows: (1) When the task is highly structured by the environment, subjects select information diagnostically, and (2) when the task is less structured, so that subjects must seek relevant information not manifest, they select information pseudodiagnostically. Possible relations to other laboratory inference tasks and to clinical judgment are discussed.     

Team-Track: A tool for investigating tracking performance in teams

Team performance and coordination have gained considerable interest in disparate fields (e.g., aviation, process control, medicine, and wartime operations). Team-Track, a C program that allows controlled experimental manipulation of team conditions, was developed to meet the research needs resulting from this interest. Using Team-Track, one can manipulate task interdependence, team staffing, relative contributions of team members, communications, and informational displays in a low-cost environment. The dependent measure of performance generated by the program is the absolute tracking error along each dimension. The program is ideal for investigating team interactions as it allows for orthogonal manipulation of team variables, therefore accommodating a multitude of research paradigms.     

Expectations for Traditional Family Roles: Palestinian Adolescents in the West Bank and Gaza

This study explored the family role expectationsof 14- and 15-year-old Palestinian young men and womenliving in the West Bank and the Gaza Strip. It wasanticipated that modernization, along with the youth's involvement in the intifada, thepopular uprising against Israeli occupation, hadfostered more liberal family role expectations among theyouth. The data were collected via questionnaire in1994-1995 from all of the ninth grade students attendingUnited Nations Relief and Works Agency (UNRWA) schoolsin the West Bank. The students completed the Arabicquestionnaire at school and took home questionnaires for their mothers and their fathers. In Gaza,samples of the ninth grade students attending UNRWAschools and of those attending schools operated by thePalestinian Ministry of Education were selected. The students' response rates were over 90%,while mothers' and fathers' exceeded 80%. Overall, datawere collected from 7,000 Palestinian families. Theresults revealed that, contrary to our expectation, Palestinian youth desire and anticipate havingtraditional families very similar to those of theirparents. Interestingly, intifada participation was notassociated with a decrease in support for traditional family roles. There were significantdifferences between the boys' and girls' perceptions offuture gender roles in Palestinian society. The youngwomen expressed more liberal attitudes towards women's roles and participation in society, while atthe same time supporting traditional familyroles.     

Can organisational safety climate and occupational stress predict work-related driver fatigue?

Road crashes are a significant cause of work-related injury and death. Driver fatigue is thought to cause 20–30% of fatal crashes. The current study utilised a survey to examine the relationship between safety climate, occupational stress and work-related driver fatigue. Drivers (n = 219) from two government organisations responded to items from the job-related tension scale [Kahn, R. L., Wolfe, D. M., Quinn, R. P., & Snoek, J. D. (1964). Organisational stress: Studies in role conflict and ambiguity. Malabar, FL: Krieger Publishing], safety climate questionnaire [Glendon, A., & Litherland, D. (2001). Safety climate factors, group differences and safety behaviour in road construction. Safety Science, 39, 157–188] and purpose-designed items on fatigue-related behaviour. Outcome measures were current self-reported, fatigue-related behaviour and self-reported ‘near (crash) misses’ during the previous 6 months. Together, occupational stress and safety climate predicted fatigue-related behaviour, accounting for 29% of the variance over and above that explained by control variables. Further, logistic regression revealed occupational stress and safety climate to be significant predictors of fatigue-related near misses. Safety climate emerged as a stronger predictor of both fatigue-related behaviour and near misses than occupational stress. Results suggest that organisations can play a part in improving the safety-related behaviours of their workforce through attention to safety climate and occupational stress.     

The development of functional response units: the role of demarcating stimuli.

An experiment with rats examined the roles of demarcating stimuli and differential reinforcement probability on the development of functional response units. It examined the development of units in a probabilistic, free-operant situation in which the presence of demarcating stimuli was manipulated. In all conditions, behavior became organized into two-response sequences framed by changes in local reinforcement probability. A tone demarcating the beginning and end of contingent response sequences facilitated the development of functional response units, as in chunking, but the same units developed slowly in the absence of the tone. Complex functional response units developed even though reinforcement contigencies remained constant. These findings demonstrate that models of operant learning must include a mechanism for changing the response unit as a function of reinforcement history. Markov models may seem to be a natural technique for modeling response sequences because of their ability to predict individual responses as a function of reinforcement history; however, no class of Markov chain can incorporate changing response units in their predictions.     

Ceding and Succeeding: How the Altruistic Can Benefit from the Selfish in Joint Decisions

We examine how the interplay of two partners’ interpersonal orientations (selfish vs. altruistic) in a decision‐making dyad impacts the extent to which the joint decision matches each partners’ individual a priori preferences. Two experiments, in which we manipulate and measure interpersonal orientations, as well as examine real consumption decisions, demonstrate the benefit of mismatching interpersonal orientations (selfish‐altruistic) in dyadic decisions. Specifically, altruistic and selfish consumers reach joint decisions that better reflect their individual preferences when working with a partner who has the opposite interpersonal orientation (heterogeneous dyad) versus a matching one (homogeneous dyad). Initial evidence suggests that this effect occurs because homogeneous dyads are more prone to engage in negotiation (communication that involves departure from one's initial position to a mutually serving position) than heterogeneous dyads. This leads homogeneous dyads to focus more on equally preferred options than on their own most preferred options, which pushes them further down both partners’ preferences lists. This research contributes to the literature on joint decision making and has important implications for consumer well‐being.
