"Participants were recruited online through students’ contacts at a large Italian university. In Study 1a, the final sample consisted of 81 participants (37 males, Mage = 21.89 years, SD = 3.73). This sample was obtained after excluding participants who self-identified as non-heterosexuals (n = 9) or who had reported technical problems (n = 5) from the 95 participants who had completed the survey.
In Study 2a, participants were recruited through students’ contacts using a snowball procedure and provided with the link to an online survey. The final sample consisted of 63 participants (35 males and 28 females; Mage = 26.57 years, SD = 5.59). From the initial sample of 117 participants who had access to the survey, we excluded those who identified as non-heterosexual (n = 9), reported technical problems (n = 13), failed to complete the survey (n = 15), or did not correctly recall the job vacancy (n = 17).
In Study 2b, groups of students were tested simultaneously in the same room. Each participant individually completed an online survey using headphones. The final sample consisted of 92 participants (3 males and 89 females, Mage = 19.45 years, SD = 1.39). From the initial sample of 152 participants, we excluded those who identified as non-heterosexual (n = 8), reported technical problems (n = 15), or failed to correctly recall the job vacancy (n = 23)."
