TESTING OF WRIST-WORN-FITNESS-TRACKING DEVICES DURING COGNITIVE STRESS: A VALIDATION STUDY
Title
TESTING OF WRIST-WORN-FITNESS-TRACKING DEVICES DURING COGNITIVE STRESS: A VALIDATION STUDY.
Creator
Chudy, Nicole S, McConnell, Daniel, University of Central Florida
Abstract / Description
The intent of this thesis was to test if one of the many fitness-tracking devices, Microsoft's Band 2 (MSB2), is accurate and reliable in detecting changes in Heart Rate (HR) and R-R intervals, during the repeated trial of two conditions of a working-memory test known as the N-Back. A 2 (devices: ECG, MSB2) x 4 (epochs: baseline 1, 1-back task, baseline 2, 3-back task) repeated measures factorial design was conducted. The participants were simultaneously equipped to the MSB2 and an...

A 2 (devices: ECG, MSB2) x 4 (epochs: baseline 1, 1-back task, baseline 2, 3-back task) repeated measures factorial design was conducted. The participants were simultaneously equipped to the MSB2 and an electrocardiogram (ECG). The results of this study validated the MSB2 for the use in a cognitive task. The study suggests that fitness-tracking devices with similar sampling rates and features are candidates for further exploration as alternatives to ECG, in hope of making the inclusion of physiological data in psychological research more available and accessible.

THE EFFECT OF COLOR ON WORKING MEMORY PERFORMANCE
Title
THE EFFECT OF COLOR ON WORKING MEMORY PERFORMANCE.
Creator
Galvez, Michelle, Neider, Mark, University of Central Florida
Abstract / Description
This paper explores the effect of color on working memory performance. Interest in Baker-Miller pink surged with the finding by Schauss (1979) that it reduced aggression in aggravated detainees. However, research behind Baker-Miller pink has been influenced by biases and methodological errors. Its effects are likely overstated. Red and blue have also been studied for their effects on creativity, approach-avoidance conflict, detail-orientation, and most importantly, stress. Further research...
Show moreThis paper explores the effect of color on working memory performance. Interest in Baker-Miller pink surged with the finding by Schauss (1979) that it reduced aggression in aggravated detainees. However, research behind Baker-Miller pink has been influenced by biases and methodological errors. Its effects are likely overstated. Red and blue have also been studied for their effects on creativity, approach-avoidance conflict, detail-orientation, and most importantly, stress. Further research has been conducted on the effects of relaxation on cognition, with the conclusion that increased relaxation leads to improvements in working memory performance. This paper tests the effect of color on working memory performance. Accuracy on the n-back was compared across 4 colors�pink, red, blue, and black. No significant differences in accuracy were found in any of the color conditions, though the main effect of load was significant. Future research can increase the sample size and utilize a cognitive task that is inherently stressful.
