ABSTRACT
This chapter introduces the field of psychophysiology and specifically explores electroencephalography (EEG), electrocardiogram (ECG), and eye tracking. It also explores how these measures through biofeedback and neurofeedback approaches can be utilized to better prepare the performer for the 'real world' environment. Psychophysiology as a field of study is related to both the anatomy and physiology of the body. EEG measures are used across a wide range of domains to understand varying aspects of human functioning. The electrocardiogram (ECG) is a method of assessing cardiac activity that involves placing electrodes on the skin, to detect electrical activity generated by the heart. Eye tracking is a set of methods and techniques used to detect and record ocular movement. Psychophysiological measures offer real potential to better understand the links between measureable cortical activity and performance. Biofeedback and neuro-feedback offer the potential to provide real-time objective data to help performers to achieve the optimal cortical states both prior to and during performance.
