ABSTRACT
This chapter focuses on many neuroergonomic metrics that can be used to assess cognitive load and how they can be used to inform instructional design. It discusses the advantages and challenges for using them and then provides more details for each of the main methods with examples of how each has been used. Numerous metrics are available for use as neuroergonomics metrics of learning. These metrics can broadly be grouped into those that measure central nervous system activity versus peripheral nervous system activity. Central nervous system measures can be further divided into those that are considered direct measurements of brain activity and those that are more indirect but can serve as a proxy for brain state. Direct measures include those that measure electrical activity, hemodynamic response, or glucose metabolism. Indirect measures include metrics like eye tracking and pupilometry. Peripheral nervous system measures include metrics such as electrodermal skin response or activity and electromyography activity.
