Breathe Easy EDA: A MATLAB toolbox for psychophysiology

Electrodermal activity (EDA) recordings are widely used in experimental psychology to measure skin conductance responses (SCRs) that reflect sympathetic nervous system arousal. However, irregular respiration patterns and deep breaths can cause EDA fluctuations that are difficult to distinguish from genuine arousal-related SCRs, presenting a methodological challenge that increases the likelihood...

Madan, Christopher R. and Kensinger, Elizabeth A. (2016) Cortical complexity as a measure of age-related brain

26 The structure of the human brain changes in a variety of ways as we age. While a sizeable 27 literature has examined age-related differences in cortical thickness, and to a lesser 28 degree, gyrification, here we examined differences in cortical complexity, as indexed by 29 fractal dimensionality in a sample of over 400 individuals across the adult lifespan. While 30 prior studies have shown...

Application of C-A fractal model and exploratory data analysis (EDA) to delineate geochemical anomalies in the: Takab 1:25,000 geochemical sheet, NW Iran

Abstract Most conventional statistical methods aiming at defining geochemical concentration thresholds for separating anomalies from background have limited effectiveness in areas with complex geological settings and variable lithology. In this paper, median+2MAD as a method of exploratory data analysis (EDA) and concentration-area (C-A) fractal model as two effective approaches in separation g...

Assessing Practitioners’ and Patients’ Needs Regarding Shared Decision-Making and Decision Aids

       Background: As part of the process of developing a decision aid for carpal tunnel syndrome (CTS) according to the Ottawa Decision Support Framework, we were interested in the level of ‘decisional conflict’ of hand surgeons and patients with CTS. This study addresses the null hypothesis that there is no difference between surgeon and patient decisional conflict with respect to test and tr...
