Chapter 5114Date outcomeSecond, we investigated the association between Date outcome and Reaction Time using a Bayesian mixed model with a Gaussian distribution (Supplementary Table 3; see Appendix G for model stability checks). We found a robust effect of Date again distractor picture on Reaction time: participants were slower by 4.41 ms to respond to the probe if the distractor image depicted someone they later indicated as a successful date compared to when the distractor image depicted someone that they did not consider a successful date during their speed-dates (bno-yes = − 4.41 [1.96], 89% CrI [− 7.51; − 1.29], pd-= 0.99), and this effect did not substantially differ per Gender (bwomen-men = − 2.48 [3.93], 89% CrI [− 10.30; 5.26], pd-= 0.74; Figure 2 top panel).When investigating the effect of Date again probe picture on Reaction Time, we did not find a robust overall effect (bno-yes = 1.68 [1.94], 89% CrI [− 1.49; 4.70], pd+ = 0.81). However, we did find a robust interaction with Gender (bwomen-men = − 9.33 [3.88], 89% CrI [− 16.80; − 1.60], pd-= 0.99). Therefore, we explored the effect of Date again probe picture within each level of Gender. For women, we found no robust effect (bwomen = − 2.97 [3.06], 89% CrI [− 8.96; 3.12], pd-= 0.84). For men, on the other hand, we found that they responded faster to the probe by 6.33 ms when it replaced a picture of someone whom they later considered a successful date during their speed-dates (bmen = 6.33 [2.36], 89% CrI [1.75; 11.00], pd+ = 1.00; Figure 2 lower panel).Voluntary attention (eye-tracking)Pre-date attractiveness ratingsWe first explored the association between Pre-date attractiveness ratingand Looking time bias, using Bayesian zero–one inflated beta regression (Supplementary Table 4; see Appendix G for model stability checks). We found that attractiveness ratings had a robust effect on voluntary attention. More specifically, participant’s attractiveness ratings of the left picture correlated positively with proportion of time spent looking at the left picture (b= 0.087 [0.0050], 89% CrI [0.079; 0.095], pd+ = 1.00), while we found the opposite effect for the attractiveness rating of the right picture (b= − 0.098 [0.0041], 89% CrI [− 0.106; − 0.091], pd-= 1.00). The results were similar for other values of Pre-date attractiveness rating: increased attractiveness ratings of the left picture were associated with an increased probability of looking at the left picture, while the opposite was true for the right picture (Supplementary Table 5).Tom Roth.indd 114 08-01-2024 10:41
