Adolescence is characterized by an increase in the intensity and frequency
of (negative)
emotions (e.g., Larson and Lampman - Petraidis 1989), heightened levels
of emotional variability (Larson et al. 1980), increases in
several types of psychopathology (e.g., Moffitt et al. 1996; Wight et al. 2004), and increased demand for independent self - regulation.
