Effects of Stress on Nonassociative Learning Processes in Male and Female Rats

In this study we assessed habituation and sensitization of the acoustic startle response (ASR) to discern whether intense, inescapable stress affects nonassociative learning differently in male and female rats. Rats were inescapably stressed 2 hours per day over 3 consecutive days. ASR magnitudes were measured at several times post-stress (1, 4, 8, and 15 days after cessation). Females generally showed greater ASR magnitudes (compared to males), but both sexes exhibited short and long-term habituation across the testing days. ASR magnitudes were only affected by stress in male subjects. The effect in males was an increase in short-term sensitization of the ASR on post-stress day-4. The results suggest that stressed males and females react differently to ASR testing, in that stress males appear to develop an exaggerated ASR response over repeated test sessions due to short-term sensitization. The source of the short-term sensitization is discussed with regards to possible stress-induced enhanced contextual learning during ASR testing on post-stress day-1.     

Learning to Understand the Balance Beam

Twenty-two university students who did not initially know the quantitative rule for predicting whether a configuration of weights placed on a balance beam would cause the beam to balance, tip left, or tip right were asked to induce the rule in a training procedure adapted from Siegler (1976). For each of a series of balance beam problems, subjects predicted the action of the beam and explained how they arrived at their prediction. Protocols revealed that although all subjects realized on early on that both weight and distance were relevant to their predictions, they used a variety of heuristics prior to inducing the correct quantitative rule. These heuristics included instance-based reasoning, qualitative estimation of distance, and the use of quantitative rules of limited generality. The common use of instance-based reasoning suggests that learning to understand the balance beam cannot be described completely in terms of a simple rule acquisition theory. Also, the variability in the use of heuristics across subjects suggests that no simple theory that depicts subjects as linearly progressing through a hierarchy of levels can be adequately describe the development of balance understanding.

Effects of Cooperative Learning on Perceived Status of Male and Female Pupils

Abstract

The effects of cooperative and individualistic learning experiences on the status of male and female American pupils were compared. Expectation states theory predicts that male pupils would have higher status than female pupils and, therefore, be more active and more influential. Social interdependence theory predicts that interaction within cooperative learning groups would result in a process of acceptance characterized by equal status of male and female pupils. Seventy-five sixth-grade boys (n = 43) and girls (n = 32) were randomly assigned to three cooperative conditions and one individualistic condition stratifying for sex, ability level, and original classroom. They participated in the study for 55 min per day for 14 instructional days. Cooperative learning resulted in greater retention and higher level learning than did individualistic learning. Although there were initial achievement differences between boys and girls, and although boys gained in status over girls in the individualistic condition, at the end of the study in the cooperative conditions there were no differences between them in achievement, verbal participation in the group, perceived leadership, and status. These results are consistent with the predictions of social interdependence theory and inconsistent with the predictions of expectation states theory. The results were basically the same in male-majority, female-majority, or equal-sex groups.     

Asian Female and Caucasian Male Couples: Exploring the Attraction

This essay examines the dynamics that trigger attraction between Asian females and Caucasian males. The author conducted ten interviews with Caucasian males who are interested in having a relationship with an Asian female; these men discussed their assumptions about Asian females. This essay then explores these dynamics in light of two books on East-West relations: Orientalism by Edward W. Said (1979) and The Asian Mystique by Sheridan Prasso (2005). Next this essay explores the psychological aspects of finding partners by drawing on the thought of John A. Sanford and C. G. Jung. And, finally, this essay concludes by addressing the need for pastoral care professionals to attend to interracial—in this case, Asian female and Caucasian male—couples.     

A Priestly Approach to Environmental Theology: Learning to Receive and Give Again the Gifts of Creation

Abstract : A priestly sensibility is here presented as a way to characterize humanity's place in creation. Sacrifice, asceticism, and gratitude are described as three distinct and practical modalities of a priestly life that contribute to the care and celebration of creation. While a priestly understanding is often associated with Orthodox environmental theology, it has the potential to inform environmental theology broadly construed.     

Beyond Male and Female: Poststructuralism and the Spectrum of Gender

ABSTRACT

Transgender explodes the notion that male and female are discrete categories. Transgender people change sex or inhabit third (or multiple) sex, androgynous, or fluid identities. I theorize this by developing and then critiquing poststructuralist transgender theory. A poststructuralist theory of transgender disassociates sex and gender, models both as constructed, and emphasizes the technologisation and commodification of the body. Poststructuralist accounts can, however, entail denial of bodily limitations, erase transgender people's subjective experience, and overlook social and political factors, such as the importance of gender categories as a basis for identity politics. I argue for the deconstruction of gender binaries to be combined with the development of a gender-pluralist, flexible, model of gender. This points to the replacement of bipolar models of gender with a gender spectrum, with important implications for conceptualizing gender. My analysis is based on empirical research with a range of transgender people.

Male and Female Preferences in Selected Career Factors

This study investigated seven factors relating to personal preferences in choosing a career. Differences between male and female preferences were also studied. While males and females express similarities relating to the seven factors, they also reveal differences that should be considered by counselors helping individuals explore career choices.     

Sex Differences in Evaluations of Female and Male Victims' Responses to Assault

In an investigation of perceptions of victim response to assult, 84 female and 70 male subjects read a narrative in which either a female or a male victim was roughly assaulted by a male stranger. The victim was described as either offering no resistance, resisting in a verbally aggressive manner, or resisting in a physically aggressive manner. Results of 3 × 2 × 2 ANOVA's revealed that women and men expected different outcomes for aggressive victim resistance. Women anticipated a worse outcome than did men, especially for victims who resisted. Men expected the most favorable outcome for the victim when he or she fought with the assailant; women expected the most positive outcome with nonresistance, especially for female victims. Female victims were seen as much more likely than male victims to be raped by the assailant. Women rated rape as a more likely outcome for physically aggressive victims while men considered rape least likely when the victim fought back. Sex differences in evaluations of victim resistance are discussed in terms of identification and empathy with the victim, goals of the victim's response strategy, and the expected effectiveness of aggressive and nonaggressive reactions to attack.     

Vaginoplasty in Male to Female Transsexuals Using Penile Skin and Urethral Flap

ABSTRACT.

Objectives: Vaginoplasty presents the main problem in male to female surgery. There are many operative techniques that can be used, but none is ideal. We present our one stage vaginoplasty in male to female sex reassignment surgery.

Patients and Methods: The principle of our technique is based on penile disassembly and usage of all penile entities for vaginoplasty except corpora cavernosa. We developed our disassembly technique on a very large number of severe hypospadias reconstruction and adrenogenital “conversions.” Penile skin flaps and urethral work are used in each of these. Our new vagina consists of two parts: a long vascularized urethral flap and a pedicled island tube skin flap created from the penile skin. The urethral flap is embedded into the skin tube. The tube, consisting of skin and urethral flap, is inverted, thus forming the new vagina. The new vagina is inserted into the previously prepared perineal cavity between the urethra, bladder, and rectum. The new vagina is fixed to the sacrospinous ligament. The labia minora and majora are formed from the remaining penile and scrotal skin.

Results: The follow-up ranged from 3 months to 6 years (mean 4.6 years). Good cosmetic and functional results were obtained in 77 out of 89 patients (87%).

Conclusions: The technique provides results that have the most normal anatomical and physiological characteristics, in comparison to other methods, since all penile entities are used (except corpora cavernosa) to form almost normal external female genitalia. Vaginoplasty using pedicled penile skin with a urethral flap could be a very good alternative to other methods of vaginoplasty.

Mind-Mindedness of Male and Female Caregivers in Childcare and the Relation to Sensitivity and Attachment: An Exploratory Study

Mind-mindedness refers to the caregiver’s ability to be attuned to the child’s mental states. Within the parent-child relationship, mind-mindedness relates to parents’ sensitive caregiving, and to children’s secure attachment. However, the same relations are still unexplored in out-of-home care settings. We investigated the associations between childcare professionals’ mind-mindedness, sensitive responsiveness and respect for autonomy, and child-caregiver attachment security. Moreover, we examined whether these relations are influenced by caregivers’ and children’s gender. Participants were 17 caregiver couples (17 males, 17 females) and 34 three-year-old children (17 boys, 17 girls), recruited in childcare centers. Mind-mindedness toward the boy or the girl (dyadic) or both children (non-dyadic), sensitive responsiveness and respect for autonomy were assessed during a semi-structured play. Attachment security was assessed through observations. Male and female caregivers had equivalent scores of mind-mindedness, sensitive responsiveness, and respect for autonomy. Similarly, children were securely attached to male and female caregivers. Girls’ and boys’ secure attachment was predicted by caregivers’ use of non-dyadic mind-related comments. For girls, but not for boys, the relation was partially mediated by caregivers’ respect for autonomy. The results are discussed in terms of their relevance for the quality of child-caregiver relationships, and children’s socio-emotional development.     

Stress and Gender in Unemployed Female and Male Managers

The purpose of this pioneering study was to investigate the overall impact of unemployment on female managers compared to their male counterparts, an area which to date has received no specific attention. A questionnaire was designed based on a review of the relevant literature and content analysis of in‐depth interviews with 40 unemployed managers. This was distributed to the 80 government run Executive Job Clubs located throughout England, and was used to gain quantitative data exploring respondents' experiences of unemployment in terms of sources of stress, stress moderators, and stress outcomes. Completed questionnaires were received from 115 female and 169 male unemployed managers registered at 46 Executive Job Clubs (return rate 47%). Multiple regression techniques were used to develop individual and comparative models of unemployment for unemployed female and male managers. The findings indicated that unemployed female managers encountered substantially greater sources of stress than their male counterparts in all aspects of unemployment. Increased stressors and less effective stress moderators resulted in female managers experiencing significantly poorer mental well‐being and greater negative physical effects during unemployment than their male counterparts. Recommendations are made to key organisations.
