SCREENS: Sleep, Circadian Rhythms, and Electronics in the EveNing Study

Summary

The proposed project aims to disentangle the impact of evening light exposure emitted from tablet devices from the impact of arousing media content on children's sleep regulation, circadian physiology and next-day emotion regulation and executive functioning.

Conditions

• Sleep
• Circadian Rhythm
• Executive Function
• Emotion Regulation

Interventions

BEHAVIORAL

no screen control with dim light and calming activities

Non-screen-based quiet activities for 1 hour before bed in room lighting 40-50 lux

BEHAVIORAL

unfiltered Bright tablet screen

Bright light screen media exposure will be delivered on an iPad Pro provided by the research team which will be set to the brightest light intensity setting for 1 hour before bed in room lighting 40-50 lux

BEHAVIORAL

Filtered dim tablet screen

Filtered dim light screen media exposure will be delivered for 1 hour before bed in room lighting 40-50 lux on an iPad Pro provided by the research team. A blue light filter will be used to alter the spectral distribution of the emitted light and the screen brightness will be dimmed to the lowest possible setting

BEHAVIORAL

Exciting content

We will create a 1-hour recording of movie clips containing exciting content from age-appropriate movies for 8- to 11-year-old children as rated by Common Sense Media.

BEHAVIORAL

Calming Content

We will create a 1-hour recording of movie clips containing calming content from age-appropriate movies for 8- to 11-year-old children as rated by Common Sense Media.
