Flashcards

Sleep quality in adolescence

Insufficient sleep and poor sleep quality are common among teenagers.

Cognitive control

Cognitive control refers to the ability to regulate thoughts and actions.

Risk-taking behaviors

Risk-taking behaviors involve actions with uncertain outcomes, often with potential for reward or loss.

Sleep quality and risk-taking

Poor sleep quality can lead to problems with cognitive control, making teenagers more likely to engage in risk-taking behavior.
