Brief Summary:
Humans are constantly exposed to a variety of light types created naturally or through artificial means Light exposure captured by the eyes impacts many physiological functions in humans including but not limited to cognitive output fatigue levels and mood regulation The level of impact on cognitive learning from different types of light on undergraduate adult students remains unclear
Detailed Description:
This study has chosen to test lights impact on adult 18 years and older undergraduate students cognitive function We hypothesize that students who wear light-enriched Type1 glasses bright light emitting glasses for one session 20 minutes will experience greater cognitive function than those who either wear light-enriched Type 2 glassesplacebo light or no glasses at all
This study will answer the following questions
1 After a single session 20 minutes of wearing light-enriched glasses on average how much did the students cognitive function increase as compared to students without light-enriched glasses
2 Does cognitive function increase to a comparable degree using both types of light-enriched glasses for a single session 20 minutes
3 Does the time of day impact the effects of light-enriched glasses during a single session 20 minutes thus improve cognitive function
4 Does time of day impact cognitive function for students who do not participate in light-enriched testing
The study will gather additional data variables on the following questions
5 After wearing either type of light-enriched glasses did the students fatigue decrease throughout the study How does this data compare to those who did not take part in light glasses testing
6 After wearing either type of light-enriched glasses did the students mood increase throughout the study How does this data compare to those who did not take part in light glasses testing
7 How does the compiled data from the questionnaires and tests compare to sleep data collected from Smart Watches
Objectives
Data points from participants will be captured through the following questionnaires and testing methods
1 Consent Form 4 min
2 Student Questionnaire 2 min Demographics
3 Chronotype Questionnaire Morningness - Eveningness Self-Assessment 4 minThis document tells you if you are an early bird or a night owl
4 Pittsburgh Sleep Questionnaire 2 min This document tells you your sleep quality
5 PHQ-9 Test 2 min This document assesses your mood
6 PROMIS Fatigue Score Test Measures your current fatigue levels
7 Trail Making Test Measures your cognitive function
Additional data variables will be obtained from sleep data captured on personal Smart Watches by participants in the study In the Student Questionnaire participants are asked if they would be willing and able to provide the research team with their personal sleep data covering a time period of two weeks prior to the study and three weeks during the study This will enable researchers to compare Smart Watch data with fatigue scores and the Sleep Quality Index Pittsburgh Sleep Questionnaire
Prior to testing light composition readings will be taken from numerous locations within the classrooms and outdoors Light readings will be obtained through a Spectral Light Meter These readings will allow the researchers to control for ambient light exposure prior to the testing of the light emitting glasses
