This report chronicles the development and production of the short film, Just Us Chickens, written, directed, and produced by Erin Randall. The film is based on several true stories told by a Diane Hill James, who grew up in Smithville, Texas during the 1950s. The script weaves together Ms. James’s experiences growing up near the famous Texas brothel, The Chicken Ranch, located in the neighboring town of La Grange. Diane and her friends would frequently spy on the brothel and once a stranger, new to town, mistook her family home as the brothel and her as a prostitute. The film, Just us Chickens, considers how these experiences could inform and influence the sexual identity of a young woman, and aims to clarify the contradictory expectations put upon female sexual development both then and now. / text

It is well established that the neurotransmitter serotonin participates in the control of sexual behaviour in the male rat. Recently, it has been found that serotonergic activity may either inhibit or facilitate sexual behaviour, depending on the subtypes of serotonin receptors involved. However, the participation of 5-HT2 receptors in the control of male rat copulation has received little experimental attention, and the published data are equivocal. In Experiments 1-4, it was established that the 5- HT2/1C agonist DCI inhibits sexual behaviour in male rats; this inhibition is effectively reversed by the antagonists ritanserin, pirenperone, and ketanserin. Comparison of these effects , with reference to the binding profiles of each drug, provided strong evidence that 5-HT2/1C receptors mediate an inhibitory influence on sexual behaviour in male rats. In addition, a tentative claim may be made that the effects of these drugs may be more attributable to 5-HT2 activity than 5-UT1C activity. ‘Wet dog shake’ behaviour in rats is known to be 5-HT2- dependent. Experiments 5—7 evaluated the novel proposition that the incidence of spontaneous wet dog shaking (WDS) by male rats in mating tests may provide a behavioural assay of concurrent 5—HT2 activity. WDS was found to be associated with copulatory inhibition in noncopulating males, compared to normal copulators, and this relationship was specific to mating situations. Activating 5-HT2/1C receptors with DOl simultaneously induced WDS and inhibited copulation. Thus, the incidence of spontaneous WDS in untreated males may reflect the function of a 5—HT2—mediated neural mechanism that tonically inhibits copulation in male rats. In Experiment 8, DOl microinjection in the nucleus raphe obscurus/inferior olivary complex also induced WDS and inhibited copulation. This suggests that the hypothesized 5- flT2-dependent inhibitory mechanism is vested in the ventromedial brainstem. Recent anatomical findings support this suggestion: cells in this region have bifurcating axons, projecting collaterally to both the medial preoptic area (implicated in sexual behaviour) and to the ventral cervical spinal cord (implicated in WDS). Overall, the results of the eight experiments provide strong evidence that 5-HT2 receptors mediate some of the inhibitory effects of serotonin on male rat sexual behaviour.

To date, only two studies have examined the accuracy of people’s perceptions of their romantic partners’ sexual satisfaction. These have yielded inconsistent results, with one study suggesting that men tend to overestimate their partners’ sexual satisfaction while women do not, and the other suggesting that women tend to overestimate their partners’ sexual satisfaction while men do not. Both studies have significant methodological limitations that make it difficult to interpret their findings. The first purpose of the current study was to investigate how similar people’s perceptions of their partners’ sexual satisfaction were to the levels of sexual satisfaction their partners reported, using an improved research methodology that addressed the limitations of past research. The second purpose of the current study was to better understand the factors that predict bias in perceptions of partner sexual satisfaction, using an integrative model that included both interpersonal and intrapersonal factors. Participants were 84 heterosexual couples who were married or cohabiting. They completed measures of sexual satisfaction (their own and their partners’), relationship satisfaction, quality of communication about sexual issues within their relationships, and also completed a task designed to assess emotion recognition abilities. We found that partner perceptions of sexual satisfaction were strongly correlated with self-reported sexual satisfaction for both males and females. We also found that males’ perceptions of their female partners’ sexual satisfaction were significantly biased, such that they underestimated their partners’ levels of sexual satisfaction. Females neither over nor underestimated their partners’ sexual satisfaction. Additionally, we found that better quality of sexual communication predicted decreased bias, while there was a trend toward better emotion recognition abilities predicting decreased bias. Further, quality of sexual communication and emotion recognition abilities interacted such that when the quality of sexual communication was good, there was no association between emotion recognition abilities and bias, but when the quality of sexual communication was poor, better emotion recognition abilities were associated with less bias. Implications of these findings are discussed.

The most commonly reported sexual concerns for women are low desire and orgasm difficulties (Laumann, Paik & Rosen, 1999; Laumann et al., 2005). Previous research indicates that women with sexual problems may have different reasons for engaging in sex than women with healthy sexual functioning (Giles & McCabe, 2009; Sand & Fisher, 2007). The current study investigated whether motivations for sex differed by levels of sexual functioning overall and specifically among women with and without problems with sexual desire or orgasm. Seven hundred and eight heterosexual women completed an online questionnaire assessing reasons for sex and sexual functioning. Women with sexual functioning concerns were more likely to endorse insecurity reasons for sex, while women without were more likely to endorse physical reasons for sex. Women experiencing low desire were less likely to endorse emotional and physical reasons for sex. Women experiencing orgasm difficulties were more likely to endorse insecurity reasons. The limitations and implications of the results are discussed.

The peacock (Pavo cristatus) has long been considered the quintessential example of a sexually selected animal, and in the last two decades, peafowl have provided widely-cited evidence for female mate choice as well as the genetic benefits of mate preferences for ornamented males. However, previous studies have failed to reach a consensus with respect to the importance of various signaling modalities in peafowl courtship. In this thesis, I repeat two previous studies of peacock train morphology and I describe the use of light by males during their courtship displays, to clarify the role of visual signaling. I confirm previous reports that removing a large number of eyespots decreases male mating success, yet I find substantial variation in mating success among normal males that cannot be explained by eyespot number. I show that these two apparently conflicting results are not contradictory, since the removal treatment modifies males beyond the normal range of eyespot number. Next, I describe the two display behaviours used by males during courtship. When males perform their pre-copulatory “train-rattling” display, they are oriented at about 45° relative to the sun on average, with females directly in front. This directional pattern suggests that train-rattling is involved in the communication of a visual signal. The “wing-shaking” display, on the other hand, is performed with females positioned behind males, and is always elicited when a model female is positioned on the shaded side of a male. The wing-shaking display may therefore allow males to control female viewing geometry. These results indicate that mate choice in peafowl is complex, and that visual signaling is important despite recent claims to the contrary. Females may avoid males missing a large number of eyespots via a threshold-based mechanism, while choosing among full-trained males based on some other (possibly visual) cue. / Thesis (Master, Biology) -- Queen's University, 2008-09-12 16:29:20.772

Female sexual arousal refers to one’s feelings of sexual excitement and pleasure and has both physiological (i.e., objective) and psychological (i.e., subjective) components. It is an important, yet difficult phenomenon to investigate. As a result, many instruments have been used in an attempt to accurately measure female arousal; however, there are problems associated with each. Furthermore, the relationship between the subjective and physiological indicators of sexual arousal appears to be influenced by the instrument used to measure physiological sexual arousal. Specifically, instruments measuring physiological arousal internally (i.e., vaginal photoplethysmography) typically yield lower correlations between measures of physiological and subjective sexual arousal than instruments examining the external genitals (i.e., labial thermistor, thermal imager), which indirectly measure blood flow. Alternatively, laser Doppler imaging (LDI) is a direct measure of external genital blood flow but has only been used in one previous study that did not assess the relationship between physiological and subjective sexual arousal. The aims of the current study were to investigate the usefulness of LDI for assessing genital blood flow in women in response to erotic visual stimuli, and to explore the relationship between physiological and subjective indicators of sexual arousal. In addition, the role of psychosocial variables in predicting physiological and subjective sexual arousal was also examined. Eighty sexually healthy women completed a psychosocial interview and questionnaires. Participants also watched three 15-minute films during LDI scanning: two nature films (measuring acclimatization and baseline blood flow levels) and one randomly assigned experimental film (erotic, anxiety, humor, or neutral). They were asked to rate their level of subjective sexual arousal throughout and following the third film. Results indicated that LDI was able to differentiate the erotic condition from the three non-erotic conditions, and that physiological and subjective sexual arousal were significantly correlated. Although the psychosocial variables did not significantly predict either component of sexual arousal, specific variables moderated the association. Psychological, sexual, and social variables, along with genital sensations, played significant roles in the relationship between subjective and physiological sexual arousal. These findings suggest that LDI is a useful instrument for measuring female sexual arousal, and that sexual arousal is a complex process that requires further empirical investigation. / Thesis (Ph.D, Psychology) -- Queen's University, 2009-08-27 10:09:26.355

This thesis examined the effect of age on sexually offensive behaviour. Research has noted both an increase in the average age of incarcerated offenders and that a higher percentage of older offenders are incarcerated for sexual offences than are younger offenders. Older sexual offenders were initially compared with younger offenders on offender and offence characteristics and these analyses revealed that older sexual offenders had a higher incidence of male victims, a younger victim age, and more intra-familial victims. Phallometric assessments of all sexual offenders were then examined to see whether sexual deviance may account for the differences found between older and younger sexual offenders in victim age and gender. These analyses revealed that the oldest and youngest offenders were more deviant than middle-aged sexual offenders and that the sexual interests of older offenders were more commonly for females. Finally, all subjects were classified as either Historical (offending had ceased, without judicial intervention, at least 7 years prior to incarceration), First-time (incarcerated for a recent sexual offence and no history of sexual offending), or Recidivist sexual offenders (currently incarcerated for a sexual offence and have at least one prior sentencing date for any sexual offence): age accounted for 12% of the variance in categorisation. Fifty-five percent of the sexual offenders age 60 years or more were found to have committed and ceased their offending at least seven years prior to incarceration (i.e., were Historical offenders). The percentage of Recidivist offenders remained relatively consistent across age groups at about 20%. No difference was found in phallometrically assessed sexual deviance between the groups of older offenders. / Thesis (Ph.D, Psychology) -- Queen's University, 2010-07-29 11:40:51.234
