About

this study examines the emergence of the visual mismatch negativity (vMMN) ERP component in response to deviations from the embedded contingency in attention bias modification treatment (ABMT) for social and generalized anxiety, and the interaction between vMMN emergence and clinical improvement. \*\*\*As of September 2017, recruitment of SAD participants has concluded.

Full description

all participants, suffering from either social anxiety disorder or generalized anxiety disorder, will receive 6 sessions of ABMT, adapted for an oddball paradigm. two of the sessions will also include simultaneous EEG measurement. the goal of the study is to determine the emergence of vMMN in response to trials deviating the embedded contingency and to examine the correlation between vMMN emergence and clinical improvement of anxiety symptoms.
