**Type III Analysis of Variance Table with Satterthwaite's method** ['anova'].

The assumptions for the model are:

The following post-hoc analysis were run:

Statistical Analysis

Participants with 'Dotloc' or 'Stimulus' Onset Error median above 3SD (*n* = 31, 18.7%) were excluded from analysis (see methods). We employed a repeated measures ANOVA using the anova() function in the *stats* R package (R Core Team, 2013; Chambers, Hastie, 1992). For our model, CESD Score ('Low' (<16) and 'High' (≥16)), and Stimulus (IAPS, POFA). were included as main effects. Random effects for Participant. was included in the model to account for their respective variation in their slopes and intercepts. Dotprobe Bias Score was used as the outcome measure.

For our analysis of Dotprobe Bias Score, our results revealed no statistically significant effect of CESD Score (*F* (1, 136) = 0.2077, *p* = 0.6493), no statistically significant effect of Stimulus (*F* (1, 136) = 2.7395, *p* = 0.1002).

This boxplot provides a comparison of [cesd_group] and across both IAPS and POFA stimuli. Both IAPS and POFA plots were nornalized to allow direct comparison.
