About this trial
The investigators have previously shown that safe, non-invasive methods of brain stimulation such as the administration of transcranial infrared light can result in improvements to cognition and emotion. The investigators hypothesize that transcranial photobiomodulation (tPBM) can be used in conjunction with attention bias assessment and modification to reduce anxiety symptoms in individuals with sub-clinical anxiety.
