Event Abstract Back to Event The neural substrate of self-perceptual speech in psychotherapy: A first look Jon Houck1*, Theresa Moyers2 and Claudia Tesche2 1 University of New Mexico, Mind Research Network, United States 2 University of New Mexico, United States Little study has been made of the neural processes underlying successful psychotherapeutic methods. Those studies that have evaluated talk therapies have not evaluated processes that occur within the therapy session itself. Motivational interviewing (MI) is an empirically supported treatment for substance abuse and a strong candidate for such a study. A mechanism of action, change talk (CT; i.e., client statements indicating a desire to change behavior), has been posited for MI. The present study is a preliminary exploration of the brain activity underlying participants’ perception of their own change talk from an MI session using magnetoencephalography (MEG). Participants were six individuals who expressed ambivalence about their substance use. This dataset represents 1/5 of the planned sample for this study, which is ongoing. Each participant had a recorded MI session with a licensed psychologist. Following each participant’s session, the precise time of each CT and counter-change talk utterance was noted, and these utterances were extracted from the session recording. During the MEG scan approximately 200 repetitions of each utterance type were presented binaurally in a random order with a random inter-trial interval. Brain activity was measured using a 306-channel whole-cortex MEG array (Neuromag, Elekta Neuromag Oy) at the Mind Research Network (Albuquerque, NM). MEG data were sampled at 1000 Hz (pass-band 0.1-330 Hz) and co-localized to the anatomical MRI of each subject using a Polhemus head position device. Head position was monitored continuously throughout the MEG session. The data were downsampled to 500 Hz and waveforms were averaged off-line over trials and band-pass filtered. Preliminary analyses are focused on the m400 response. Results will be presented. Progress at this point indicates that, despite the privacy and logistical hurdles of obtaining stimuli from treatment sessions, such data can be reliably acquired and analyzed.
