The Performance-Variability Paradox, Financial Decision Making, and the Curious Case of Negative Hurst Exponents

Physiological arousal variability accompanying relations-oriented behaviors of effective leaders: Triangulating skin conductance, video-based behavior coding and perceived effectiveness

“…Empirical tests of this thesis have focused on the dynamic nature of only one phenomenon, for instance, either work motivation or team coordination or performance. They found that there are fluctuations in these work-related variables (Arrieta, Navarro, & Vicente, 2008;Gorman, Cooke, & Amazeen, 2010;Guastello et al, 2014). For instance, when an individual showed performance that fluctuates between high and moderate levels, this led to higher overall performance (Guastello et al, 2014).…”

While these studies have shown that variability in important phenomena, including behavior, can inform our understanding of the workplace as a dynamic, social context, they do not tell us how variability in important workplace phenomena is associated with bodily phenomena that co-occur.…”

Individual, Relational, and Contextual Dynamics of Emotions

“…We also know that emotions have significant impacts on economic decision-making (e.g. see Bechara & Damasio, 2005), that such impact might take the form of a nonlinear self-organizational process (Dishion, 2012) that appear as emergent patterns that vary over time (Guastello et al, 2012;Guastello, Reiter, Shircel, & Timm, 2014), and that these effects are related to entropy levels (Guastello et al, 2013). At the same time, however, we still know little about how time affects emotion in the process of decision-making under varied uncertainty levels (i.e.…”
