Can Non-drug Antidepressant Treatments Influence the Way the Human Brain Processes Information?

University of Oxford·interventional·Posted Sep 27, 2018·Updated Oct 3, 2018

In Brief

A clinical study evaluating Bright light treatment lamp and Sham negative ion generator for Bright Light Treatment and 2 related conditions. Completed, enrolled 50 participants across 1 site.

Detailed Summary

This study aims to investigate the effects of a single session of bright light treatment (BLT) on emotional information processing in healthy volunteers. We hypothesised that BLT can acutely push the processing of emotional information towards a prioritisation of positive (relative to negative) input. To test this hypothesis, healthy volunteers were randomly allocated to receive either bright light treatment or sham-placebo treatment and study participants as well as investigators were blind as to which treatment was used. After treatment, all participants underwent testing with the Oxford Emotional Test Battery, an established set of psychological tasks that allow to assess how emotional information is processed.
