Females in the forefront: time-based intervention effects on impulsive choice and interval timing in female rats

Impulsive choice has been implicated in substance abuse, gambling, obesity, and other maladaptive behaviors. Deficits in interval timing may increase impulsive choices, and therefore, could serve as an avenue through which suboptimal impulsive choices can be moderated. Temporal interventions have successfully attenuated impulsive choices in male rats, but the efficacy of a temporal intervention has yet to be assessed in female rats. As such, this experiment examined timing and choice behavior in female rats, and evaluated the ability of a temporal intervention to mitigate impulsive choice behavior. The temporal intervention administered in this study was successful in reducing impulsive choices compared to a control group. Results of a temporal bisection task indicated that the temporal intervention increased long responses at the shorter durations. Further, results from the peak trials within the choice task combined with the progressive interval task suggest that the intervention increased sensitivity to delay and enhanced timing confidence. Overall, these results indicate that a temporal intervention can be a successful avenue for reducing impulsive choice behavior in female rats, and could contribute to the development of behavioral interventions to prevent impulsive choice and maladaptive behaviors that can be applied to both sexes.     

From Social Construction to Relational Construction: Practices from the Edge

In this paper, I talk about Ken Gergen??s influence in the communication discipline. Beginning with his ground-breaking publications in the 1970??s (Gergen 1973, 1978), we see him challenging the taken for granted separation of theory and practice, scholar and practitioner. One of Ken??s many contributions?Cregardless of disciplinary domain?Chas been the nurturing of forms of practice being developed by creative and innovative practitioners and young scholars alike. There are several key resources that are woven throughout Ken??s work that have continued to inspire and influence practitioners working in mental health, healthcare, organizations, schools, communities, and peace building endeavors. The most central of these resources include (1) centering relational processes which, in turn, generate the expansion of (2) collaborative, participatory practices that embrace alternative worldviews through a (3) a reflexive stance. Ken has challenged himself and all of us to stay on the edge because it is on the edge that new relational possibilities can be created. He has invited us to embrace the edge as the place of great comfort; comfort in knowing that there will always be possibilities for forging new ways of making meaning together.     

Caller characteristics, call contents, and types of assistance provided by caller sex and age group in a Canadian Inuit crisis line in Nunavut, 1991-2001

Analysis of calls made to a northern Canadian Inuit crisis line in the territory of Nunavut between 1991 and 2001 revealed that the majority of users were adult females who called to discuss problems primarily related to relationships and loneliness/boredom. Younger callers tended to make prank calls. The volunteer staff used mostly empathetic listening and suggestions. Referral recommendations made were primarily to social services. Although some callers experienced a language barrier, others found the service to be helpful. Results suggest that the crisis line was underused by young Inuit males who represent a group that are most in need of crisis intervention.     

Gender Differences in Spatial Task Performance as a Function of Speed or Accuracy Orientation

Performance differences in spatial abilities as a function of gender may be modified by practice and relevant background experiences, as well as by directions given in laboratory situations. We examined whether a focus on speed or accuracy influenced performance in various spatial domains, using several different scoring techniques. Men and women from a small, predominantly White private college completed tasks of spatial perception, spatial visualization, and mental rotation under one of three conditions: speed-emphasis, accuracy-emphasis, or control. Participants also provided information concerning experiences pertinent to spatial ability. Results revealed relative parity between men and women on tasks of spatial visualization and spatial perception; speed/accuracy orientation did not alter these findings. Men outperformed women on mental rotation, but only when scored in a strict manner and when explicitly told to focus on accuracy, but not when directional emphasis was absent or geared toward speed. Self-reported background in math, sports, and the arts was unrelated to performance. The results are discussed in terms of women's efficacy beliefs about performing tasks explicitly designated as spatial in nature.
