Abstract: | The interaction between neuroticism and extraversion is thought to predict affective variability. In this study, neuroticism and extraversion were assessed with questionnaires, and affects were measured by experience sampling, with five daily assessments over 2 weeks. Affective variability was studied within a three-dimensional affective space whose three axes were oriented along the main affective dimensions: positive affect, negative affect, and activation. Quantile regression mixed-effects models allowed predicting zones in which affective states were most likely to occur according to personality. Beyond the well-known effect of personality on affect level, high neuroticism and/or high extraversion were accompanied by heightened affective variability. Results were interpreted as potentially reflecting positive feedback loops oriented toward negative affect for neuroticism, and toward positive affect and activation for extraversion. |
