Sexual assault between acquaintances represents a pervasive but chronically under-reported issue in Australia. Miscommunication Theory attributes this phenomenon to a breakdown in the effective communication of consent between male and female partners. Enthusiastic Consent has been subsequently introduced to address these issues of miscommunication by defining consent as an explicit, non-coerced and ongoing agreement. However, debate currently persists regarding the practicality and effectiveness of this definition of consent in light of competing evidence regarding men and women’s reliance on contextual, rather than explicit consent cues. This study therefore used the context of sex-work to simultaneously manipulate explicit consent, the exchange of payment, and contextual consent, the presence of physical resistance, and examine their competing influence on perceptions of consent within a possible sexual assault. Participants (N = 192) were asked to read a hypothetical vignette describing a possible sexual assault occurring between a sex-worker and her client, before completing composite measures of: perceived consent, and victim and perpetrator responsibility. As predicted, the encounter was considered significantly more consensual when consent was explicitly given, rather than explicitly denied. Additionally, as predicted, participants believed the encounter was significantly less consensual, when the victim displayed physical resistance rather than displaying no resistance. Contrary to predictions, when explicit consent was ambiguous, participants considered the encounter to be similarly non-consensual to when consent was explicitly denied. These results offer preliminary support for Enthusiastic Consent as a tenable solution to rates of acquaintance sexual assault, while actively contradicting many of the assertions of Miscommunication Theory. Possible future research that could extend the validity of these findings and the application of Enthusiastic Consent is discussed.
