"Adolescents are often thought to be extraordinarily moody, moving from joy to sadness to irritation to anger over the course of a morning or afternoon. And the source of teenage moodiness is often presumed to be the influx of hormones associated with puberty - 'hormones running wild.' In fact, evidence indicates that adolescents are moodier than children or adults, but this is not primarily due to hormones (Steinberg, 1999). Scientists often find that rapid increases in hormone levels are associated with greater irritability and greater impulsivity, but the correlations tend to be small and are found primarily in early adolescence (Buchanan, Eccles, & Becker, 1992)."

"If hormones are not responsible, then what causes teenage moodiness Some insights come from an elaborate study in which teenagers carried electronic pages for a week (Csikszentmihalyi & Larson, 1984). When paged by researchers, the adolescents briefly described what they were doing and how they felt. The record of a typical adolescent is shown in Figure 8.3." "His mood shifts frequently from positive to negative, sometimes several times in a single day. For this boy, like most of the adolescents in the study, mood shift were associated with changes in activities and social settings.
