Teenagers and health

Adolescence is a key period, both because it makes the growing individual more fragile, and also because of the habits that are taken then and which will influence health thereafter.

During this difficult period and on emerging from it, the teenager often reduces the notion of health to “being and staying in shape.” Unfortunately, educators and health carers are ill‐trained to respond to the specific needs of teenagers.     

The long-term retention of time: A developmental study

Two experiments investigated the age-related changes in long-term retention of duration and their effects on time judgement. Children aged 3, 5, and 8 years old were given a temporal bisection task with or without a 15-min interfering task (Experiment 1), or a retention delay lasting for 0 min, 15 min, or 24 hr (Experiment 2) between the presentation of the standard durations and the comparison stimulus durations. An interfering task and the increase of the retention delay significantly decreased the time sensitivity in the 3- and the 5-year-olds, and to a greater extent in the younger children, but had no effect in the 8-year-olds. This decrease in time sensitivity with the interfering task or the retention delay might be due to an increase in the variability of the remembered duration.
