The ENLIGHT project investigates whether light therapy represents an effective way to improve the lives of people with dementia. The lack of studies on light as a non-pharmacological therapy including people with dementia makes this important for further theoretical and methodological development.

ENLIGHT wants to investigate how different light conditions affect cognition and mood. 

Work package(WP) 1 and 2 consist of exposure to four different light conditions; blue, red, bright white, and dim white light. WP1 tests the effects of light on cognitive performance. WP2 includes two tests 1) an emotion recognition protocol, the perception of positive, negative and neutral facial expressions, and 2) implicit emotional learning (conditioning). The experiments will take place in the light laboratory at the Faculty of Psychology. Saliva samples are taken to measure melatonin. Heart rate variability are recorded.

WP1 and 2 will include three groups; young healthy adults, seniors with no cognitive impairment and people with dementia. This could give an insight into whether any variation in effect is due to dementia or age-related changes.
