Interventions

  • no screen control with dim light and calming activities — BEHAVIORAL
    Non-screen-based quiet activities for 1 hour before bed in room lighting 40-50 lux
  • unfiltered Bright tablet screen — BEHAVIORAL
    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
  • Filtered dim tablet screen — BEHAVIORAL
    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
  • Exciting content — BEHAVIORAL
    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.
  • Calming Content — BEHAVIORAL
    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.

Study Details

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.

Arms

  • Experimental: Group 1
    Children will participate in 2 exposure conditions in their own homes (i.e., experimental and internal negative control), facilitated by research staff (one week apart, counterbalanced to control for possible order effects). The internal negative control will be the same for all groups, but the experimental exposure will differ. Both exposures will take place for 1 hour before bed in room lighting (40-50 lux). Experimental exposure: children in Group 1 will be exposed to a tablet with unfiltered bright screen light and exciting media content (BL/EC). Internal negative control exposure: children will participate in non-screen-based quiet activities
  • Experimental: Group 2
    Children will participate in 2 exposure conditions in their own homes (i.e., experimental and internal negative control), facilitated by research staff (one week apart, counterbalanced to control for possible order effects). The internal negative control will be the same for all groups, but the experimental exposure will differ. Both exposures will take place for 1 hour before bed in room lighting (40-50 lux). Experimental exposure: children in Group 2 will be exposed to a tablet with unfiltered bright screen light and calming media content (BL/CC). Internal negative control exposure: children will participate in non-screen-based quiet activities
  • Experimental: Group 3
    Children will participate in 2 exposure conditions in their own homes (i.e., experimental and internal negative control), facilitated by research staff (one week apart, counterbalanced to control for possible order effects). The internal negative control will be the same for all groups, but the experimental exposure will differ. Both exposures will take place for 1 hour before bed in room lighting (40-50 lux). Experimental exposure: children in Group 3 will be exposed to a tablet with filtered dim screen light and exciting media content (DL/EC). Internal negative control exposure: children will participate in non-screen-based quiet activities
  • Experimental: Group 4
    Children will participate in 2 exposure conditions in their own homes (i.e., experimental and internal negative control), facilitated by research staff (one week apart, counterbalanced to control for possible order effects). The internal negative control will be the same for all groups, but the experimental exposure will differ. Both exposures will take place for 1 hour before bed in room lighting (40-50 lux). Experimental exposure: children in Group 4 will be exposed to a tablet with filtered dim screen light and calming media content (DL/CC). Internal negative control exposure: children will participate in non-screen-based quiet activities

Primary Outcome Measure
