Abstract: This thesis is an investigation of cognitive control strategies and how they are observable in heart rate (HR) and respiration. Cognitive control ensures that our actions align with our behavioural goals. This control can be divided into proactive and reactive control by the dual mechanisms for control framework. When using proactive control people actively anticipate goal-relevant events/actions prior to their occurrence. Those using reactive control make adjustments that are applied on-the-fly as events unfold. In this thesis, we used the AX-CPT task, which provides behavioural indices of control strategy together with physiological measures of HR and respiration to probe whether each control strategy has a unique physiological signature. Anticipatory HR deceleration was observed regardless of control strategy, but was especially sensitive to the consequences of proactive control use. Moreover, respiration appeared to more closely track global variations in control strategy.
