Figure 4

The relationship between levels of marital stress (averaged over 9 years) and responding to positive pictures as indexed by corrugator EMG activity during initial reactivity, early and late recovery epochs. The residuals of both measures are plotted, after controlling for age, gender and sample of origin (as well as for initial positive-picture reactivity in the recovery estimates). (Note that the relationship at late recovery epoch remains significant without the outlier, r (113) = .25, p = .007).
