Visual reinforcement in the female Siamese fighting fish, Betta splendens

Operant conditioning with Betta splendens (Bettas) has been investigated extensively using males of the species. Ethological studies of female Bettas have revealed aggressive interactions that qualitatively parallel those between male Bettas. Given these similarities, four experiments were conducted with female Bettas to examine the generality of a widely reported finding with males: mirror-image reinforcement. Swimming through a ring was reinforced by a 10-s mirror presentation. As with males, ring swimming was acquired and maintained when mirror presentations were immediate (Experiments 1, 2, and 3) and delayed (Experiment 4). The failure of conventional extinction (Experiments 1 and 2) and response-independent mirror presentations (Experiment 3) to maintain responding confirmed the reinforcing properties of mirror presentation. These results extend previous findings of mirror images as reinforcers in males of the same species and illustrate a complementarity between behavioral ecology and the experimental analysis of behavior.     

Feminism and Women's Autonomy: the Challenge of Female Genital Cutting

Feminist studies of female genital cutting (FGC) provide ample evidence that many women exercise effective agency with respect to this practice, both as accommodators and as resisters. The influence of culture on autonomy is ambiguous: women who resist cultural mandates for FGC do not necessarily enjoy greater autonomy than do those women who accommodate the practice, yet it is clear that some social contexts are more conducive to autonomy than others. In this paper, I explore the implications for autonomy theory of these understandings of the relation between culture, FGC, and women's agency. I review the range of worldwide FGC practices – including "corrective" surgery for "ambiguous genitalia" in Western cultures as well as the various initiation rites observed in some African and Asian cultures – and the diverse cultural rationales for different forms of FGC. I argue that neither latitudinarian, value-neutral accounts of autonomy nor restrictive, value-saturated accounts adequately explain women's agentic position with respect to FGC. I then analyze a number of educational programs that have enhanced women's autonomy, especially by strengthening their introspection, empathy, and imagination. Such programs, which engage women's autonomy skills without exposing them to autonomy-disabling cultural alienation, promote autonomy-within-culture. This understanding of autonomy as socially situated, however, entails neither endorsement of FGC nor resignation to its persistence.     

Role of female behavior in controlling population growth in mice

Sex ratio does not appear to be a factor in generating the characteristic population growth curve. Freely growing populations of house mice, consisting of all females and one male, stopped their growth at approximately the same densities as normal sexratio populations used as references. The mechanism(s) of female control of population dynamics may be related to female aggressive behavior. As the all-female/one-male populations approached their maximum size, the females began to show wounding patterns and social hierarchies in much the same manner as males in populations with normal sex ratios. The male in each of the populations was severely wounded in the posterior region, and each lost its tail as a result of injuries which could have been inflicted only by the females. The female social hierarchy can be seen only when there has been reproduction and population growth. Assembled populations of all females rarely exhibit aggressive behavior. Female aggression becomes apparent only when the population approaches its maximum size and thereafter. These data are consistent with the hypothesis that males are competitive among themselves for territory and social rank, and ultimately to mate with the females. Other investigators have indicated that females respond to population size, which may reflect increased competition between the females with the establishment of territories. Thus female agression may control population growth, a role previously ascribed to male aggression.     

Role of female aggression in prevention of infanticidal behavior in male common voles,Microtus arvalis (Pallas, 1779)

Infanticidal behavior of male common voles (Microtus arvalis) was investigated in relation to the age of unfamiliar pups. Sires from 18 pairs were removed after parturition of their offspring and replaced by unfamiliar males at different ages of the neonates. In group 1, containing six females with their offspring, the new male was introduced into the females' cages on day 1 after the parturition. In group 2 the new male was introduced on day 5 after parturition and in group 3 on day 9 after parturition. The male was removed after 3 days and the neonates recounted. Male common voles killed up to 100% of the neonates in litters containing neonates younger than 9 days by rapid bites to the head of the neonates (groups 1 and 2, mortality rates of 0.86 and 0.38). However, with older pups, a mortality rate of 0.06 was observed while 33% of the intruder males showed signs of injuries (group 3). These findings show that infanticidal behavior of male common voles represents one factor of pup mortality. The results are discussed in relation to changes in the degree of maternal aggression and in the context of the social system of the common vole for solving the conflict between postpartum estrous mating and infanticidal behavior of male common voles.

Pre-breeding aggression in male and female three-spined sticklebacks (gasterosteus aculeatus)

The reactions of 34 female and 32 male three-spined sticklebacks to a conspecific were observed in the month before the breeding season. Factor analysis indicated that the organization of the response in the two sexes was very similar; in both cases, axes labelled “aggression,” “threat,” “curiosity,” and “sex” emerged, with male fish having significantly higher scores on the first factor and females on the second. Any theory of the causes of aggression in sticklebacks should accommodate these facts.     

Offensive and defensive bite-target topographies in attacks by lactating rats

The attacks by resident lactating Wistar rats on sexually naive conspecifics of both sexes were examined. Male and female intruders were equally attacked in terms of frequency and number of bites, but the topographies of biting seen in these encounters were different. Similarly to male-male agonistic interactions, females were attacked in a fashion which avoided bites to the head and snout (“offensive” attack), whereas males were frequently bitten on such vulnerable regions (“defensive” attack). This dichotomy in bite pattern suggests that different motivations and functions underlay maternal aggression in these situations. The defensive attack on males may be a deterrent to infanticide since only male intruders counterattack lactating females and kill their pups. The attack on females may be concerned with resource competition.     

Laboratory and questionnaire measures of aggression among female parolees with violent or nonviolent histories

Female parolees were recruited into a laboratory study to determine the relationship between their previous aggression history, questionnaire measures of aggression, and behavioral measures of aggressive responding using a laboratory methodology: the Point Subtraction Aggression Paradigm (PSAP). Subjects were assigned to a violent or nonviolent group based on their criminal history. Subjects participated in sessions in which they were given three response options: (1) nonaggressive responding that earned money, (2) aggressive responding that ostensibly subtracted money from another fictitious person and was defined as aggressive since it resulted in the ostensible delivery of an aversive stimulus (subtraction of money) to another person, and (3) escape responding that protected the subject's earnings from periodic subtractions initiated by the fictitious other person. Results indicated that the violent female parolees emitted significantly more aggressive responses than subjects in the nonviolent group. This study provides additional external validity as well as evidence for convergent and discriminant validity for PSAP laboratory measurement of human aggressive responding and extends these findings to female parolees. Comparisons to previously published data with male parolees showed that gender differences were found among violent but not nonviolent parolees. Aggr.

APPRECIATING DIFFERENCE: ROY SCHAFER ON PSYCHOANALYSIS AND WOMEN

The author describes and appreciates Roy Schafer's critique of Freud's view of female psychology and his other contributions to the psychoanalytic literature on women, noting his then‐novel emphasis that took into account social and cultural factors in analytic treatment. She relates the influence on Schafer's work of his ambiance in that era: the Yale University Student Health Services during the social turmoil of the 1970s (where she was his supervisee), with the university becoming coed, as well as the theoretical plurality even in the early days of the Western New England Psychoanalytic Institute.     

Psychoanalytic considerations about the anti‐oedipal condition in Heinrich von Kleist’s Penthesilea and in the analysis of Miss M1

Based on Heinrich von Kleist’s drama Penthesilea and a clinical case, this study seeks to demonstrate a theoretical concept that is developed and identified as the anti‐oedipal condition. This state involves a regressive insistence on suffocating any form of oedipal maturation and, with it, any form of genital–sexual desire; it damages, even destroys, any form of intellectual–creative curiosity. A specific form of defensive organization, the anti‐oedipal condition, is sought out when psychic development, when oedipal–genital maturation requires re‐establishing contact with a sort of inner terra cremata, an emotional domain that once had been supposed to be eliminated due to catastrophic experiences that could not be integrated. This defensive organization dominated Kleist’s Amazons as well as Miss M. What happened first in both instances was a regression to and fixation at the anti‐oedipal condition, but the paths leading out of this incapsulation were antipodal.
