Brief Summary: The goal of this clinical trial is to systematically investigate two prominent factors in teenagers daily life Caffeine and sleep restriction SR and their combined influence on sleep cognition and behavior in healthy adolescents The main questions it aims to answer are

The effects of caffeine under conditions of SR and SE

on sleep pressure and sleep continuity
on BOLD activity differences in reward related areas during a reward task monetary incentive delay task and on reaction times behavioral aspect in the same task
on BOLD activity differences during a risk taking task wheel of fortune task and on risky decision-making behavioral aspect in the same task

Participants will be either in the SR or SE condition between-subject The protocol consists of 2x of approximately one week in which a participant will receive caffeine or placebo within-subject at the last two evenings

The experiment consists of an ambulatory and a laboratory phase

The ambulatory phase consists of 5 nights including 3 stabilization nights 8h sleep opportunity prior to 2 nights consisting of either SR with 6h sleep opportunity or SE with 95h sleep opportunity Participants will wear an actiwatch and fill out sleep diaries during this period
The laboratory phase will be the 6th evening night and morning of the protocol and will be spent in our lab Participants will do the following
treatment caffeine vs placebo intake
saliva sampling
drug screening
cognitive tests including risk-taking and reward task
filling in questionnaires sleep diary sleep quality sleepiness mood expectancy
waking and sleep with EEG

The next day participants will undergo an fMRI scan including the following

resting-state scan
structural scan
arterial spin labeling scan
reward task scan
risk-taking task scan

Around the scan participants will fill outundergo

saliva sampling
questionnaires reward task mood sleepiness expectancy
