Design outcomes

Primary

Measure	Time frame	Description
Working memory capacity	7 weeks	Objective memory performance as assessed by a sample of neuropsychological tests from Cambridge Cognition - Cantab tests (Spatial Working Memory (SWM), One Touch Stockings of Cambridge (OTS), Stop Signal Task (SST)) Including Paced Auditory Serial Addition Test (PASAT).

Secondary

Measure	Time frame	Description
Subjective memory complaints (SMC)	7 weeks	Subjective memory complaints (SMC) are measured by a self-report questionnaire The Everyday Memory Questionnaire We estimate prevalence of subjective memory complaints and examine the correspondence between SMC and symptoms of depression, anxiety, sleep disturbances, chronic fatigue and chronic pain.
Transfer to inhibition	7 weeks	Transfer to inhibition is demonstrated by significantly reduced Stop Signal Reaction Time on The Stop Signal Task
