Abstract: Heart rate variability (HRV), depression symptoms, and reduced autobiographical memory specificity (AMS) have all been independently found to have associations with inhibitory control capacity and executive functioning.Inhibitory control is the ability to effectively inhibit the processing of distracting information in order to achieve a specific goal.Inhibitory control is thought to be able to be depleted, and can be exhausted through cognitively demanding tasks.One index of inhibitory control is vagally-mediated high frequency (HF) HRV, which reflects parasympathetic activity.Vagally-mediated HF-HRV is found to be positively correlated to inhibitory control.Interestingly, depression is characterized by a variety of cognitive deficits and biases, including reduced inhibitory control and reduced autobiographical memory specificity (AMS).Individuals with reduced AMS tend to recall and describe events from their past in a vague, over-general manner.Reduced AMS has been associated with poor prognosis in depression, and delayed recovery from depressive episodes. While both depression and AMS have relationsto inhibitory control capacity, the relation between HRV and AMS has not yet been investigated, and certainly not the interaction of HRV, AMS, and depressive symptoms.To assess this relationship, participants (N=120) included in the study were given the Autobiographical Memory Test (AMT), Beck Depression Inventory (BDI), and also completed measures of resting v Vita 2006..........
