Demeter's Compromise: Separation,Loss, and Reconnection in Mothers with Daughters Entering Adulthood

Drawing on contemporary theory of female development that focuses on the dynamics of the mother/daughter relationship regarding issues of separation and individuation, this article examines the treatment of a middle aged mother as she navigates her way through her daughter's adolescence and early adulthood. Psychoanalytic object relations, psychoanalytic relational theory, and feminist theory serve to frame an understanding of the case material in terms of developmental challenges that are uniquely female. Issues around mother/daughter attachment, separation, competition, conflict, and love are explored in the relationships between the patient and her mother, the patient and her daughter, and the patient and the therapist. The therapist's countertransference, intensified by her relationships with her own mother and daughter, suggests the possibility of both pitfalls and opportunities in the treatment. The article attempts to address a gap in psychoanalytic developmental theory, which offers little understanding of the challenges for women in midlife.     

女性对新异性事件加工的偏向:来自ERP的证据

采用修订后的oddball范式,结合ERP技术考察女性与男性在加工中性新异刺激时的差异。ERP结果表明,在早期已经出现新异性效应。在300-500ms内,新异刺激在男性和女性被试中都比标准刺激诱发了更大的LPC。在500-700ms内,新异刺激仅在女性被试中比标准刺激诱发更大的LPC,在男性被试中没有显著差异。这些结果表明男性和女性都对中性新异刺激表现出加工偏向,但是女性对其加工的时间比男性更长。这可能与女性容易对显著性(salient)的刺激进行沉思(rumination)相关。     

Interfemale aggression in adult bank voles (Clethrionomys glareolus)

Agonistic interaction may play a large role in shaping the social structure and spatial distribution of rodents such as Clethrionomys glareolus. Aggressive and non-aggressive behaviors of adult bank vole females were investigated with a home cage test during 10 min sessions. The number of attacks was significantly higher in virgin females kept with intact adult males than in singly reared females or those exposed to male urine. Bulbectomy of the tested females completely inhibited the male stimulating effect. This indicates that males influence the behavior of females by activating their olfactory systems. Aggressive behavior in pregnant or lactating females, which is linked to maternal behavior, was also tested. Female bank voles between 11 and 17 days of pregnancy or lactating at 3–4 days or 9–10 days attacked their partners significantly more frequently than virgins did. Females that had direct contact with males, even if they were not fertilized, appeared to be more successful in same-sex competition. Aggr. Behav. 24:53–61, 1998. © 1998 Wiley-Liss, Inc.     

Gonadal hormones and intrasexual aggressive behavior in female bank voles (Clethrionomys glareolus)

The effects of gonadal hormones on aggressive behavior in the female bank vole was investigated in 10 min home cage tests. Ovariectomized (ovx) or intact females injected with oil, with progesterone (P), with a mixture of progesterone and estrogen (P+E), or with testosterone (T) alone were confronted in a resident-intruder test with unfamiliar, nonoperated females as intruders. Intact females showed aggressive behavior more frequently than ovx females. Ovx females injected with P, with P+E, or with T made significantly more attacks, and these attacks lasted longer than those observed for oil-treated voles. The results indicate that P, the typical female hormone, is responsible for aggressive behavior in female bank voles; however, only T increased the duration of interfemale aggression. Aggr.

Inhibition of aggression by progesterone and its metabolites in female Syrian hamsters

The sequence of estradiol and progesterone is known to inhibit the expression of aggression in female hamsters. Despite the key importance of progesterone in the inhibition of aggression, little is known of the mechanisms through which progesterone may exert this effect. Three experiments were performed to assess the degree to which metabolites of progesterone can affect aggression in female Syrian hamsters. Systemic estradiol treatment followed by injections of either progesterone (300 μg IP) or 4‐pregnen‐21‐ol‐3,20‐dione (DOC, 300 μg IP) reliably inhibited aggression. Systemic injection (75, 150, or 300 μg IP) of either 5α‐pregnan‐3α,21‐diol‐20‐one (THDOC) or 5α‐pregnan‐3α‐ol‐20‐one (3α,5α‐THP) did not affect aggression. Intracerebroventricular infusion of 3α,5α‐THP following systemic estradiol treatment also did not affect aggression. In a third experiment, female hamsters were given systemic treatments with estradiol and progesterone that were subthreshold with respect to inhibition of aggression. In these females, intracerebroventricular infusion of THDOC inhibited aggression. These results indicate that metabolites of progesterone can inhibit aggression, most notably in synergy with progesterone itself. Aggr. Behav. 27:372–381, 2001. © 2001 Wiley‐Liss, Inc.     

On the dual nature of maternal aggression in rats

Presentation of a natural predator, a cat, was used to differentiate elements of maternal attack by female rats on a male intruder. Following exposure (without direct physical contact) of post-partum females to a cat or to a toy stuffed cat (control group), the females were replaced in their home cages and presented with a male intruder rat. Cat exposure reliably decreased lateral attack to the intruder, as well as locomotion, but had no effect on either jump attack or an upright defensive posture (boxing). Since predator exposure produces a somewhat durable increase in defense, along with inhibition of nondefensive behavior, these results suggest that maternal aggression represents a mixture of offensive, usually related to competition, and defensive (protective) behaviors. The results indicate that maternal aggression, as a parental care behavior, appears to be at least partially resistant to fear. © 1996 Wiley-Liss, Inc.     

男性监控配偶、配偶不贞与精子竞争的关系

精子竞争是指同一女性产道中两个或两个以上男人的精子相互竞争卵子的过程。女性得到社会承认的性伙伴可能因精子竞争失败而损失惨重,因为女性私通可能引起男性投资于不携带自己基因的后代。过去研究表明进化而来的男性配偶监控策略可以防止女性不贞,减少精子竞争失败的危险。当前研究发现男性与配偶进行性行为后离别时间越久,男性就越采取出其不意地打电话、独占配偶时间、威胁对配偶感兴趣的男性等手段来监控配偶     

Offender and crime characteristics of female serial arsonists in Japan

This study of Japanese female serial arsonists examined their crimes and background characteristics. The data were a sample from the national police register containing arson cases resulting in charges in Japan between 1982 and 2005. Serial arsonists were 6% of the arson offenders and 12% of these were female, resulting in 83 female serial arsonist data sets. The mean age was 37.6 years and 43% were unemployed. Nearly half were married. Only 28% had a documented history of mental problems and 22% had a prior arrest, usually for theft (19%). Female serial arsonists are characterised by going to a place near their home with a lighter and setting fire directly to combustible materials. Non‐metric multidimensional scaling was used to analyse 33 variables related to the offences. The arsons could be differentiated in terms of either expressive or instrumental sources of action. Expressive arsons were opportunistic and impulsive acts, motivated by emotional distress. The fires were mostly set close to home. Expressive arsons were characteristic of 66% of the females. Instrumental arsons were often motivated by revenge and involved planned and goal‐directed behaviours. They were committed by 13% of the females. Instrumental arsonists tended to travel further from home. Copyright © 2007 John Wiley & Sons, Ltd.     

Effect of conspecific sex on aggression during pregnancy and lactation in golden hamsters

The effect of conspecific sex on maternal aggression in hamsters was determined by comparing the frequency of aggressive responses by dams continuously housed with either a virgin male or female cagemate during pregnancy and lactation. Dams easily established aggressive dominance over male cagemates soon after pairing, and their aggression was low thereafter for the duration of pregnancy and lactation. The aggression of dams with females, on the other hand, tended to fluctuate with highs during mid pregnancy and mid lactation and lows around birth. When dam aggression was low around birth, female cagemates frequently became aggressively dominant, and several dams lost their litters. The higher aggression of dams toward females than males is probably a reflection of greater intrasexual competition for environmental resources that includes pups.
