A total of 315 participants performed the experiment, and 255 participants were included in the analysis: 172 females, 83 males (mean age, 24.06 years; SE, 0.13). Sixty participants were excluded from analysis: 37 females, 23 males (mean age, 24.36 years; SE, 0.24). Exclusions were due to unawareness to conditioning during conditioning sessions, incoherent image rating, low performance in memory tests, or low performance in discrimination tasks (these criteria are detailed in the text).
