“…After answering basic demographic questions concerning only age, sex, nationality, ethnicity, relationship status, and handedness, participants were asked to listen to all 32 voice clips (with each joke being spoken by 4 voices; both the masculinised and feminised versions of the male and female joke-teller) in a self-paced online questionnaire on a computer in a quiet lab setting. The manipulation check was carried out to ensure that aggressive jokes were not included as this could introduce personality associations which may interfere with the perception of voices (Cowan & Little, 2013a;Zeigler-Hill et al, 2013). Thus, participants were asked to rate the jokes on a 7 point scale (ranging from 1 'high in affiliation', to 4 'neutral', to 7 'high in aggression') to identify if any of the jokes could be classed as aggressive.…”
