Psychological Impact of Pubertal Events
Wide variability in adolescent adjustment
Biological, psychological and social forces combine to influence development
In industrialized nations, many years of education lead to prolonged dependence on
parents and postponement of sexual gratification → extension of adolescence
Reactions to Pubertal Changes
Depend on prior knowledge, support from family, and cultural attitudes
Today many girls are more informed about menarche
Boys usually get info about spermarche from reading or online
Get less social support
Those who feel better prepared tend to react more positively
Absence of a single widely accepted marker for physical and social maturity makes the
process of becoming an adult more confusing
Pubertal Change, Emotion and Social Behavior
Adolescent Moodiness
Higher pubertal hormone levels → greater moodiness
Negative moods linked to greater number of negative life events
Negative life events increased steadily from childhood to adolescence
Teenagers react to them with greater emotion
Moods were less stable; strongly related to situational changes
Change in sleep schedule possibly due to increased neural sensitivity to evening light
More evening social activities, part time jobs and electronics
Sleep deprivation → depressed mood, poor academic achievement, risky behaviors
Negative mood levels off in late adolescence when emotions are more stable
Supportive family + peers → more positive moods
Parent Child Relationships
Adolescents resist spending time with family and become argumentative
Rise in parent child conflict
May be due to adaptative value - young leaves family around puberty
Discourages sexual relations between blood relatives
But adolescents in industrialized nations are economically dependent on parents →
psychological distancing
Teens demand to be treated as adults
Gap between views on readiness for new responsibilities → conflicts
Pubertal Timing
Late maturing boys - viewed as more anxiety and depressed
Early maturing boys viewed as relaxed, independent, confident, and attractive
Actually report more psychological stress, depressed mood, and problem
behaviors than late maturing ones
Early maturing girls - unpopular, withdrawn, lack self confidence, prone to depression
More involved in deviant behavior
