| Outline of Final Research Achievements |
Heart rate variability biofeedback (HRVBF) is known to have clinical utility in the treatment of depression. This study explored whether HRVBF could modify cognitive bias favoring negative stimuli in depressed individuals. College students (N = 14) with self-reported depression assessed by BDI-II participated in the study. Event-related potentials (ERPs) were recorded during a go/no-go task (Task-1), in which target words were neutrally, or negatively valenced. This was followed by HRVBF condition, or fast paced breathing as a control condition. The go/no-go task (Task-2) was administered again, immediately after each condition. In Task-1, the ERP P300 amplitudes were larger for negatively valenced than for neutrally valenced words. In participants with high BDI scores, the P300 amplitude for negatively valenced words decreased from Task-1 to Task-2 during the HRVBF condition. Results suggest that HRVBF might modify the cognitive processing of negative stimuli in depressed individuals.
