In order to compare the prevalence of certain symptoms in adolescence with those at other ages, 6,034 apparently normal subjects aged 9-60 years were studied by questionnaire. Fear of blushing and fear of being looked at showed a maximum in the mid-teens and a subsequent gradual decrease both in males and females. They were more common in females at most ages. The anxiety symptoms also showed a peak in the mid-teens but there was a period of relative increase in the forties. Episodic illusions and the idea of being talked about started to decrease with age in adolescence.
