Relation between disposition personality in emotional response In "Determinants of Emotion Duration and Underlying Psychological and Neural Mechanisms" by Verduyn et al, the authors discuss various dispositions that account for how long an emotional effect lasts:


Resilience
Depression level
Extraversion and neuroticism


Extraversion and neuroticism are two components of the OCEAN model of personality. How were these two attributes determined to be most important when it comes to dealing with emotions? What is the relation between personality and disposition?
Those two personality factors can be considered as a component of disposition. Two publications established that extraversion and neuroticism as being the most correlated with emotional processing.

In "Adding Liebe und Arbeit: The Full Five-Factor Model and Well-Being" from McCrae et al (1991), the authors correlated three measure of weel-being with 429 adult men and women.


  Consistent with previous rescarch, neuroticism was negatively, and 
  extraversion was positively, related to well-being. Both agreeableness
  and conscientiousness were also significant independent predictors


In "The happy personality: a meta-analysis of 137 personality traits and subjective well-being" by DeNeve et al (1998) examine 137 personality constructs across 9 literature search strategies to find determine the effect on positive and negative affect.


  The traits most closely associated with SWB were
  repressive-defensiveness, trust, emotional stability, locus of
  control-chance, desire for control, hardiness, positive affectivity,
  private collective self-esteem, and tension. When personality traits
  were grouped according to the Big Five factors, Neuroticism was the
  strongest predictor of life satisfaction, happiness, and negative
  affect. Positive affect was predicted equally well by Extraversion and
  Agreeableness.
