Participant characteristics
| Males | Females | ||||
|---|---|---|---|---|---|
| Mean | SD | Mean | SD | Group difference | |
| Age | 13.36 | 1.04 | 13.46 | 1.02 | t(47) = −0.34, P = 0.739 |
| Relational bullying | 1.01 | 0.83 | 1.16 | 0.80 | t(47) = −0.63, P = 0.533 |
| Relational victimization | 1.42 | 1.02 | 1.52 | 0.86 | t(47) = −0.40, P = 0.690 |
| Mean accuracy (%) | 96.4 | 3.1 | 98.1 | 3.0 | t(47) = −1.96, P = 0.056 |
| Mean RT (ms) | 1376.5 | 314.2 | 1169.8 | 246.9 | t(47) = 2.55, P = 0.014 |
Note: Relational bullying and relational victimization were square-root transformed due to skew in the distributions. Mean accuracy and RT are reported for the face matching task (mean behavioral data include face and shape matching trials). For the purposes of testing sex differences and dummy-coding, the participant who identified as non-binary was coded as male.
