Abstract

Heart rate data is useful in studying stress levels, workload, and fatigue while participants perform cognitively demanding tasks (Goldberger, Goldberger, & Shvilkin, 2012). The standard in collecting physiological heart rate (HR) data is the use of electrocardiogram (ECG).Unfortunately the use of ECG can be time consuming, costly, and requires specialized training. There have been no previous studies to determine whether or not wrist-bands are valid for measuring difficult cognitive tasks. The objective of this study to validate fitness-tracking devices as an alternative to ECG and thus make the inclusion of physiological data in psychological research more accessible.

A 3x2x2 between subjects ANOVA will be conducted using 30-40 participants. Conditions will be (ECG, Basis, MSB2 x HR, Galvanic Skin Response (GSR) x wrist location+counterbalancing). GSR is an established measure of workload and stress (Shi, Ruiz, Taib, Choi, & Chen, 2007) All participants will be simultaneously equipped to all three devices while recording baseline data as well as physiological data during the 1-back and 3-back working memory task. A previous study (Goodie, Larkin, & Shauss, 2000) tested the validity by taking one data point in the form of an average representing the mean HR of that task. In our study, we will be taking 10 data points, each representing the average of a minute. This allows us to look at precise physiological changes in the cognitive tasks. Expected results are to be positive, seeing accurate validity and reliability for the fitness-tracking devices.
