An experimental analysis of exposure to “explicit” heterosexual stimuli as an effective variable in changing arousal patterns of homosexuals

The effect of exposure to explicit heterosexual stimuli on heterosexual arousal was experimentally analyzed in four homosexuals in a series of single case experimental designs. Each subject was sequentially exposed to films of female or male sexual content under positive therapeutic instructions. Penile response to female slides in separate measurement sessions increased during exposure to the female film, decreased during exposure to the male film, and increased once again when the female film was reinstated. The increase in penile response to female stimuli was paralleled in many instances by changes in masturbatory fantasy, reports of arousal and heterosexual behavior outside the laboratory. Increasing heterosexual arousal had little effect on homosexual responsivity. Results are discussed in terms of exposure facilitating extinction of avoidance responses toward females and providing new sexual fantasy content.     

Reduction of sadistic sexual arousal by olfactory aversion: a case study

A sexual sadist was treated by an olfactory aversion procedure for eight weeks. Pre-treatment assessment of sexual arousal showed high levels of response to sadistic stimuli as well as high arousal to non-sadistic heterosexual stimuli. In treatment the inhalation of the gas of an odoriferous chemical agent, valeric acid, was paired with slide presentations of sadistic materials while penile erection was monitored. The aversive stimulus immediately and permanently suppressed the response for the duration of treatment. In separate measurement sessions, with valeric acid absent, deviant response remained suppressed and nondeviant response was unaffected. Post-treatment reassessment revealed very low levels of response to sadistic stimuli. Follow-up sessions showed that the deviant response was absent eight months following the conclusion of treatment.     

Treatment of bisexual pedophilia by a biofeedback-assisted self-control procedure

A bisexual pedophile was treated for 88 days using a biofeedback procedure which displayed his erection response to sexually deviant stimuli on a closed-circuit television monitor. Told to develop a strategy of self-control using the biofeedback, his response to young boys and girls was treated sequentially in a multiple baseline design. His concurrent response to boys, girls and adult males was evaluated in separate generalization sessions. The treatment was successful in suppressing deviant response while maintaining nondeviant response in strength. Debriefing of the client following treatment revealed that he had used a self-developed technique of covert sensitization to suppress deviant response and had used the biofeedback to confirm and validate this self-control strategy.     

Fading to increase heterosexual responsiveness in homosexuals

Heterosexual responsiveness, measured by penile responses and reports of behavior, was strengthened in three homosexuals through a fading procedure. Using two slide projectors, colored slides of nude females were superimposed on colored slides of nude males. As the sexual response was emitted, the nude male was faded out and the nude female faded in. Heterosexual arousal decreased when the fading procedure was reversed or stopped and increased once again when fading was resumed. Homosexual arousal remained high during this experiment but had decreased in two subjects at follow-up. The results suggest that fading was responsible for altering stimulus control of sexual arousal and that aversive techniques may not be necessary in the treatment of sexual deviation.     

AN EXPERIMENTAL INVESTIGATION OF PREORGASMIC RECONDITIONING AND POSTORGASMIC DECONDITIONING

The effects of pre- and postorgasmic presentation of moderately erotic cues were assessed in an analogue study. Eight heterosexual male volunteers (18 to 23 years) participated in three assessment (baseline, termination-of-treatment, and two- to three-month followup) and eight masturbatory conditioning sessions. Three slides of nude females of initially equal erotic value were paired respectively with the plateau, refractory, and resolution phases of the subjects' sexual cycles. Over treatment, stimuli paired with the plateau phase increased significantly in penile tumescence indices of eroticism; conversely, stimuli paired with the refractory phase decreased significantly. The conditioned effects on tumescence were largely extinguished at followup. While treatment did not alter short-term subjective indices of eroticism, stimuli presented during the refractory phase were rated significantly less erotic than the other stimuli at followup. The findings suggest that the “pairing” model of orgasmic conditioning is insufficient to account for previously reported clinical findings. A broader conceptualization of the mechanisms of orgasmic conditioning, and implications for treatment are discussed.     

Prognostic factors and classification issues in the treatment of secondary orgasmic dysfunction

The present study examined patient and problem characteristics as well as therapy process factors associated with success and failure in sex therapy for secondary orgasmic dysfunction. Ss were 23 married couples selected for emotional and marital stability; all wives were suffering from secondary orgasmic dysfunction. Sexual functioning and satisfaction were evaluated before and after 15 sessions of therapy. Ss also engaged in daily self-monitoring throughout the therapy program. Two criteria of therapeutic success were used: the couples' global sexual harmony and the females' frequency of orgasmic response in couple sexual activity. Higher pre-treatment masturbation rates by the female, as well as better awareness of her partner's sexual tastes and preferences, were related to poor therapeutic outcome. Greater pre-treatment enjoyment of non-genital caressing by the female as well as higher incidence of interpersonal orgasmic response in the past were associated with therapeutic success. The theoretical and research implications of the present findings are discussed.     

Dimensions of subjective female orgasmic responsiveness

Results of recent psychological research have been at odds with the major physiological evidence on the nature of female orgasmic responsiveness. Although female orgasm appears to be a single process physiologically, subjective reports by women indicate that individual differences in their experience is multidimensional. The basis for the discrepant findings is analyzed via two studies of reported orgasmic experiences in women. One sample of 115 sexually experienced women yielded data that replicated the finding that coital and masturbatory orgasmic responsiveness can be statistically distinguished and independently assessed, thus indicating that sample selection associated with prior research could not explain the result. A separate sample of 101 sexually experienced women were given an instrument that assessed coital responsiveness but differentiated masturbatory responsiveness into dimensions associated with masturbation when alone and with a partner without intercourse. A confirmatory factor analysis substantiated the existence of the three dimensions of female orgasm. However, female orgasmic responsiveness was highly correlated across the three dimensions so that it was possible to isolate a large second-order factor of general orgasmic responsiveness that is consistent with most of the physiological evidence on the unitary nature of orgasm. Correlates of the orgasm scales with background data revealed some discriminant validity for the three dimensions of responsiveness.     

Male-related chemical cues promote sexual receptivity in the female musk shrew

The role of conspecific chemical cues in the activation of sexual behavior was investigated in the female musk shrew (Suncus murinus). In Experiment 1, virgin female musk shrews were exposed to either clean cages or cages recently vacated by an adult male. Regardless of whether the male used for the sexual behavior test was "familiar" to the female (having spent the 24 h exposure in his vacant cage) or "unfamiliar," females exposed to male-related cues received mounts from males significantly sooner than females exposed to clean cages. In Experiment 2, females housed for 24 h in a cage soiled by an adult male allowed males to mount significantly sooner than females housed in a cage soiled by a castrated male, another female, or a clean cage. These results demonstrate that chemical cues, produced exclusively by adult males, promote sexual receptivity in female musk shrews.     

Facilitating sexual arousal via anger,aggression, or dominance

The hypothesis that either an angry emotional state or the expression of aggressive behavior facilitates sexual arousal has been the subject of considerable speculation but relatively little research. In a series of studies, Barclay found that anger increased sexual arousal as measured by the amount of sexual imagery produced in response to TAT-like stimuli that depicted males and females in dominant and submissive roles. In the present research, a series of experiments was conducted to determine whether such facilitation can be generalized beyond the specific procedures used by Barclay. Subjects (151 males and 136 females) in three experiments were angered by being negatively evaluated by a confederate identified as a fellow subject. Some subjects were subsequently given an opportunity to aggress; additionally, some subjects were exposed to male- and female-dominant pictorial stimuli. Results indicated that neither anger instigation nor the opportunity to engage in aggressive acts influenced self-reported sexual arousal. There was consistent evidence, however, that portrayals of dominance influenced perceptions of the stimulus person's sexuality. Though anger and aggression do not seem to facilitate sexual arousal, dominance cues (which can be confounded with anger manipulation) clearly elicit perceptions of sexuality.     

Autoeroticism,sexual satisfaction,and sexual adjustment among university females: Past and current patterns

A review of the research literature reveals a general paucity of rigorous scientific analyses of masturbatory behavior in adult females. The availability of a data base from a pilot study concerned with self‐perceptions of the orgasmic response during masturbation and sexual intercourse has provided the opportunity to investigate the role of masturbation in the sexual repertoire of university female students. This data base also permitted an assessment of what differences, if any, exist among those respondents who are currently masturbating, have masturbated but not currently masturbating, and have never masturbated.

Questionnaire data were obtained from 512 never‐married, female university students enrolled in lower and upper division courses in anthropology, biology, psychology, and sociology. Respondents in the currently masturbating group were more likely to have experienced their first orgasm via masturbation, to have had greater success in achieving orgasm via masturbation, and to enjoy masturbating alone more when contrasted with the not currently masturbating group. Other findings suggest that masturbating to orgasm serves as an enhancement and/or supplement to sexual intercourse. The currently masturbating respondents were more likely to have experienced sexual intercourse and those who had experienced sexual intercourse reported a greater number of sex partners than those respondents in the never masturbated group. Finally, no statistically significant differences were found in sexual adjustment, using self‐evaluations of physiological satisfaction and psychological satisfaction, between the three respondent groups.     

Increased conformity to a fellow deviant as a function of prior deviation

A subject was induced to publically report his opinions on a variety of issues. A group of confederates disagreed with the subject; one confederate agreed with him. Thus, the subject deviated from the majority of the group, but received social support from one other individual. Each subject was then paired with one individual from the previous group, and regardless of his pairing, was subjected to a constant amount of conformity pressure from the confederate on a new set of judgments. Deviant subjects conformed more to the confederate who had previously given them social support than they did to a previous majority member. This increased conformity was found in two studies, (1) females judging physical realities and, (2) males reporting their opinions on attitudinal issues. Ratings taken in the second study demonstrated that the deviant subject felt increased liking for and similarity to the confederate who initially provided him with social support, but comparisons between various experimental groups indicated conformity to a confederate was not completely predictable from the subject's liking for that confederate. Instead, conformity was greatest following an experience of deviation from the majority.     

Evaluating the Psychometric and Measurement Characteristics of a Measure of Sexual Orientation Harassment

We use classical test theory (CTT) and item response theory (IRT) methodologies to examine the psychometric and measurement properties of an instrument designed to assess sexual orientation harassment among military personnel (N?=?71,989). CTT analyses indicated that items were unidimensional and exhibited adequate levels of reliability. IRT analyses demonstrated that the items functioned similarly and exhibited appropriate levels of item discrimination. However, the analyses also suggested that the sensitivity of the items may be limited. Differential test functioning analyses provided evidence of the measurement equivalence of the instrument across male and female respondents. The findings provide support for the psychometric properties and measurement equivalence of the instrument for measuring sexual orientation harassment among male and female military personnel. We discuss the implications of our findings for future research on sexual orientation harassment in the workplace.     

Consistency of the labial temperature change measure of human female eroticism

Six adult, human female volunteers participated in a study to determine the consistency of their pattern of sexual arousal to two erotic films over two experimental sessions. Sexual arousal was assessed objectively by means of continuous measurement of temperature changes of the labia minora and subjectively by periodic self-ratings. Each subject developed increases in labial temperature to both film presentations that ranged from about 0.10°C to 1.36°C above basal levels. The amount of temperature change in a subject's labia minora during the first film presentation was significantly correlated with that during the second film, and there was a reasonable degree of consistency across the two sessions with regard to the rate at which the subject's labial temperature subsided towards basal levels after the cessation of erotic stimulation. Labial temperature changes and subjective ratings were also significantly correlated during each of the two film presentations.     

SATIATION THERAPY: A PROCEDURE FOR REDUCING DEVIANT SEXUAL AROUSAL

Two single-case experiments demonstrated the efficacy of satiation therapy with adult males who had long-standing deviant sexual interests. The procedure involves the pairing of prolonged masturbation (1 hour) with the verbalization by the patient of his deviant sexual fantasies and in both cases the designs permitted the attribution of control over aberrant responding to the satiation therapy. The results are discussed in terms of the possible active ingredients of the procedure.     

Matching to Reinforcer Value: Human Concurrent Variable-Interval Performance

A male paedophile offender chose between pairs of sexual stimulus classes in a two-operandum procedure with reinforcement arranged according to concurrent variable-interval variable-interval schedules. Condition 1 involved choice between slides of women and slides of men; condition 2, slides of men vs. slides of children; and condition 3, slides of women vs. slides of children. On the assumption that the subject matched his ratios of responses and times on the two operanda to reinforcer value, estimates were obtained from the data in conditions 1 and 2 of the values of slides of women and of children relative to slides of men. These yielded predictions of the relative allocations of responses and of time in condition 3. The predicted and obtained outcomes were similar. The results support the use of matching-based scaling of reinforcer values in the prediction of choice between qualitatively different reinforcers and extend the application to a human subject, the two-operandum procedure, and sexual stimuli.     

Exhibitionists: sexual preferences for exposing

An assessment of the sexual preferences of exhibitionists and matched non-offenders, revealed greater arousal to scenes of exposing among the offenders but the actual degree of deviant preferences was not marked. Closer analyses of the individual response profiles, using various criteria for deviance, indicated that only a small proportion of exhibitionists displayed deviant arousal. We take these results, along with the findings from previous research, to deny the primacy of sexual motivation in exhibiting behavior. We also consider these results to indicate that there is little value in determining the sexual preferences of exhibitionists when planning treatment or estimating their risk to re-offend.     

Sex-role orientation and stereotypes about male-female sexuality

An experiment was conducted to examine the stereotypes about human sexuality held by persons of different sex-role orientations. Sex-typed and androgynous subjects were given bogus information about the sexual experience of another person. This other person was either a male or a female and either high or low in sexual experience. The subjects were then shown some erotic slides and asked to predict how sexually aroused the target person would be by viewing these stimuli. Additionally, the subjects were asked to rate the target person on traits of a sexual and evaluative nature. The results showed, as predicted, that the sexual experience of a female target influences how much sexual arousal is attributed to her. Female targets of high experience were attributed more arousal than inexperienced female targets. For male targets, no such difference was found. Ratings of the targets on an evaluative dimension revealed a double standard: Sexually experienced females were rated lower than were inexperienced females; no difference was found for male targets. In addition, sex-typed subjects tended to express more traditional stereotypes of sexuality than androgynous subjects. The influence that these stereotypes may have in guiding malefemale interactions is discussed.This article is based on the author's doctoral dissertation, submitted to Kansas State University.

Treatment of secondary orgasmic dysfunction: a comparison of systematic desensitization and sex therapy

Forty-eight couples complaining of secondary orgasmic dysfunction were randomly allocated to one of three treatment methods or to a control group. Sexual function, sexual anxiety and satisfaction with the total relationship were evaluated in a pretest, an intermediate test (after 12 therapeutic sessions) and a follow-up test. The intermediate test revealed significant improvement in the sexual function of women treated by systematic desensitization, and that of women and men treated by an adapted version of the Masters and Johnson method. The follow-up test showed significant improvement in women and men treated by desensitization. Both methods significantly improved the satisfaction with the total relationship in men and women, and desensitization significantly reduced sexual anxiety in men and women. The results of combined treatment —desensitization followed by treatment according to Masters and Johnson—were very poor. The control group showed no significant changes. Evaluation of the differences between the treatments revealed a near-significant difference in sexual function of women in the intermediate test, with desensitization and the Masters and Johnson method yielding better results than combined treatment or no treatment.     

Assessment of sexual preference using a choice reaction time task

The purpose of this study was to investigate the use of a choice reaction time task, during which slides of sexually explicit and neutral stimuli were used as an interference task, to differentiate between groups of individuals on the basis of their sexual preference. Twenty subjects, in each of the four groups (heterosexual males, heterosexual females, homosexual males, and homosexual females), participated in this study. Sexual orientation was determined by self-report. Subjects were given a choice reaction time with interference task, followed by a recall incidental learning task. A significant higher-order interaction was found among gender, orientation, and stimulus type for all four groups. This interaction indicated a longer reaction time to slides depicting preferred sexual partners than to nonpreferred sexual partners or neutral scenes. These results indicate that sexual arousal does interfere with cognitive processing. A main effect for gender was found for the incidental learning task, with males having the fewest errors.     

Responsiveness to estrous chemostimuli in male rats (Rattus norvegicus) of different ages

Previous findings indicate that Norway rats (Rattus norvegicus) respond differentially to estrous chemostimuli in early infancy and that adult male sexual responsiveness to such chemostimuli depends on infantile experience with suckling odors (Fillion & Blass, in press). The development of behavioral responsiveness to estrous chemostimuli in male rats from late infancy to adulthood was examined in this study. Preweanling, adolescent, and adult males were observed for 20 min in the presence of an anesthetized estrous or an anesthetized diestrous female. This was, for adolescent and adult subjects, the first heterosexual encounter since weaning. Rats in each age-group responded differentially according to female state, but in distinct, age-related ways. Preweanling spent more time investigating the female's body if she was estrous. Adults expressed the same affinity but by more focused investigation directed perivaginally. Adolescents showed no female-directed bias but groomed themselves more if the female was estrous. These data identify developmental continuities and discontinuities in male rat behavior toward sexually receptive females.
