Conditions
Interventions
The current study aims to investigate whether biofeedback can be used to
interrupt AVH perception. Part 1 of the study observes which, if any, sites
demonstrate a correlation with EMG activity durin
either the behavioural engagement
task is changed or instead of engagement, the relaxation of relevant
musculature is trained.
The experimenter notes which strategies were successful, how many attem

Inclusion criteria
Inclusion criteria: In order to be eligible to participate in this study, a subject must meet all of the following criteria: -Able to understand procedures and agree to participate in the study by giving written informed consent -Report having heard voices, measured through the Questionnaire for Psychotic Experiences. And who report that: (1) voices are distinct from thoughts and had a *hearing* quality and (2) voices are experienced daily -Or in the case of control participants, report NOT having heard voices through the Questionnaire for Psychotic Experiences.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The main parameter of the current study is EMG activation during AVH. Study part 1 compares EMG during AVH with baseline (rest) and behavioural tasks (humming, whistling and reading out loud). Study part 2 measures the success of interruption of AVH related EMG activation through behavioural tasks. | — |
Secondary
| Measure | Time frame |
|---|---|
| A secondary study parameter pertains the difference in EMG activation in participants experiencing AVH and a control group who do not experience AVH. This is measured in study 1 by comparing baseline activation patterns and task related EMGs between the AVH+ and AVH- groups. | — |
