“…Such approaches include the evaluation of balance of tolerance/sensitivity to regular stress through comparing work/non-work days or waking/sleeping states (Davydov, Shapiro, & Goldstein, 2004;Davydov, Shapiro, et al, 2005;), or behavioural, subjective and physiological components of emotional reactivity to simple stimuli (e.g., pain), or complex information such as aversive tasks, films or texts in laboratory studies (Ottaviani, Shapiro, Davydov, Goldstein, Mills, 2009;Davydov et al, 2008;Lysenko & Davydov, 2008). These tests of reactivity to minor stressors have been proposed to assess a level of adaptive or maladaptive coordination of behavioural and physiological responses in particular contexts as a trait representing a mood-protecting endophenotype and maintaining a balance of negative and positive experiences (Wichers et al, 2007a;.…”
