Pictorial cues and sexual desire : an experimental approach

The cognitive processing of sexual and non-sexual pictorial stimuli was examined to see whether picture rating and recognition tasks have potential utility as a means of assessing levels of sexual desire. Previous research has revealed slower responding to sexual compared to neutral semantic cues in persons with lower self-reported sexual desire. The present study investigated whether sexual pictorial cues evoked a similarly slower responding in people reporting low sexual desire compared to other individuals. A total of 136 participants completed two self-report measures of sexual desire (the Hurlbert Index of Sexual Desire and the Sexual Desire Inventory) before carrying out tasks involving affective ratings and recognition memory for pictorial stimuli. Participants were classified into relatively low, average, and higher groups on the basis of their scores on the desire measures. The stimuli were selected from the International Affective Picture System, and the tasks included (1) rating the valence, arousal, and sense of dominance or control for each picture, (2) recognition of previously seen images, and (3) a second rating of pictures viewed earlier. Level of sexual desire did not influence responding in the male participants. Female participants with lower sexual desire rated sexual images less pleasant and less arousing than the other participants, and completed picture recognition tasks more quickly. Sexual desire levels significantly influenced the interest ratings women gave to sexual pictures. We also found sexual content induced delays. These delays were not significantly different among desire groups. The variation in responding linked to levels of sexual desire in women suggests that more investigation of this methodology in a clinically diagnosed population might contribute to an understanding of low desire, and help design interventions addressing distress due to lack of sexual desire.

Subjective wellbeing as an affective construct

The affective component of Subjective Wellbeing (SWB) was investigated according to the Circumplex model of affect. Structural equation modelling demonstrated that affect is the dominant component of SWB and it is concluded that core affect is the central component of SWB, and the driving force behind SWB homeostasis.

Subjective Wellbeing as an affective construct

This thesis quantifies the normative characteristics of Subjective Wellbeing amongst Australian high-school age students using the Personal Wellbeing Index adapted for school children. No previous study has undertaken this task. The results confirm the homeostatic model and corroborate previous research suggesting that Subjective Wellbeing is a construct driven primarily by Core Affect.

An empirical investigation of women's affective responses to filmed violence

This thesis examined the subjective emotional responses of women to depictions of violent and sexually violent film. Findings highlighted the significance of contextual factors, such as the gender of the perpetrator and victim upon viewers, and found that exposure to sexual violence in the media has important implications for women. The portfolio's four case studies demonstrate the complexities involved in making risk judgements and treatment planning given the diversity of offences and needs, as well as the implications these decisions can have when determining the amenability of offenders to specific sex offender treatment.

Individual differences in affective responses to violence and sexual violence

The thesis aimed to identify and compare individual differences in anger related affective responses upon exposure to neutral, violent and sexually violent film. The findings revealed that both graphic and non-graphic sexually violent film content may have a stronger impact on viewers' anger levels than exposure to standard violent film. The portfolio examined in four case studies the utility of the Violence Risk Scale when seeking to identify factors associated with risk of violent recidivism and subsequent treatment targets for intellectually disabled offenders . Treatment indications must consider the impaired cognitive and adaptive abilities and the difficulties inherent in modifying the behavioural characteristics of intellectually disabled offenders.

Comparing multiple discrepancies theory to affective models of subjective wellbeing

The Subjective Wellbeing (SWB) literature is replete with competing theories detailing the mechanisms underlying the construction and maintenance of SWB. The current study aimed to compare and contrast two of these approaches: multiple discrepancies theory (MDT) and an affective-cognitive theory of SWB. MDT posits SWB to be the result of perceived discrepancies between multiple standards of comparison. By contrast, affective-cognitive theory asserts that SWB is primarily influenced by trait affect, and indirectly influenced by personality and cognition through trait affect. Participants comprised 387 individuals who responded to the 5th longitudinal survey of the Australian Unity Wellbeing Index. Results of Structural Equation Modelling (SEM) indicated the poorest fit to the data for the MDT model. The affective-cognitive model also did not provide a good fit to the data. A purely affective model provided the best fit to the data, was the most parsimonious, and explained 66% of variance in SWB.

Regular exercise participation mediates the affective response to acute bouts of vigorous exercise

Physical inactivity is a leading factor associated with cardiovascular disease and a major contributor to the global burden of disease in developed countries. Subjective mood states associated with acute exercise are likely to influence future exercise adherence and warrant further investigation. The present study examined the effects of a single bout of vigorous exercise on mood and anxiety between individuals with substantially different exercise participation histories. Mood and anxiety were assessed one day before an exercise test (baseline), 5 minutes before (pre-test) and again 10 and 25 minutes post-exercise. Participants were 31 university students (16 males, 15 females; Age M = 20), with 16 participants reporting a history of regular exercise with the remaining 15 reporting to not exercise regularly. Each participant completed an incremental exercise test on a Monark cycle ergometer to volitional exhaustion. Regular exercisers reported significant post-exercise improvements in mood and reductions in state anxiety. By contrast, non-regular exercisers reported an initial decline in post-exercise mood and increased anxiety, followed by an improvement in mood and reduction in anxiety back to pre-exercise levels. Our findings suggest that previous exercise participation mediates affective responses to acute bouts of vigorous exercise. We suggest that to maximise positive mood changes following exercise, practitioners should carefully consider the individual's exercise participation history before prescribing new regimes.
