Figure 2From: Hypervigilance or avoidance of trigger related cues in migraineurs? - A case-control study using the emotional stroop task Emotional Stroop indices for faces. Emotional Stroop indizes for faces comparing the color naming latencies of negative stimuli with the latencies of neutral stimuli (ESI-N) and comparing the response latencies of negative stimuli with the latencies of positive stimuli (ESI-P). ESI of all three groups are displayed (Co: control group, EM: episodic migraine group; FM: frequent migraine group). Analyses of variances revealed a marginally significant group difference for ESI-P ((*) p=.05), and for ESI-N ((*) p=.075). For both indices there were significant differences between the Co and the FM group (ESI-N: p=.038; ESI-P: p=.016). The ESI-N of the controls differed significantly from zero (t(19) = 3.94, p=.001), whereas the ESI-N of the migraine groups were not significantly different from zero.
