“…The eccrine sweat glands are innervated by sympathetic fibers, and, in normal ambient temperatures, palmar, finger (or plantar) glands reflect responses to psychological rather than thermoregulatory stimuli [48]. Therefore, EDA is considered as an ideal way to monitor the autonomic nervous system and, more specifically, its sympathetic branch [30].…”

Skin Admittance Measurement for Emotion Recognition: A Study over Frequency Sweep

Abstract:The electrodermal activity (EDA) is a reliable physiological signal for monitoring the sympathetic nervous system. Several studies have demonstrated that EDA can be a source of effective markers for the assessment of emotional states in humans. There are two main methods for measuring EDA: endosomatic (internal electrical source) and exosomatic (external electrical source). Even though the exosomatic approach is the most widely used, differences between alternating current (AC) and direct current (DC) methods and their implication in the emotional assessment field have not yet been deeply investigated. This paper aims at investigating how the admittance contribution of EDA, studied at different frequency sources, affects the EDA statistical power in inferring on the subject's arousing level (neutral or aroused). To this extent, 40 healthy subjects underwent visual affective elicitations, including neutral and arousing levels, while EDA was gathered through DC and AC sources from 0 to 1 kHz. Results concern the accuracy of an automatic, EDA feature-based arousal recognition system for each frequency source. We show how the frequency of the external electrical source affects the accuracy of arousal recognition. This suggests a role of skin susceptance in the study of affective stimuli through electrodermal response.

“…During a first meeting (T1) participants were 7 R-PAS and Vulnerability to Stress administered the Rorschach task according to R-PAS guidelines; about one week later (T2) their EDA was recorded during exposure to a mild laboratory stress-inducing task, involving a threephase baseline-stress-recovery trial. Because EDA changes from baseline to stress are supposed to index sympathetic activity and vulnerability (Papez, 1937;Christie, 1973;Boucsein, 1992; Ionescu- Tirgovişte and Pruna, 1993;Kozarić-Kovacić et al, 2010;Mestanik et al, 2014), we hypothesized that Stress and Distress R-PAS variables measured at T1 would positively correlate with increased EDA changes from baseline to stress at T2 (i.e., with increased sympathetic reactivity to stress). Additionally, assuming that EDA changes from baseline to recovery reflect prolonged sympathetic arousal following stress, we also tested correlations between Stress and Distress R-PAS variables and EDA changes from baseline to recovery.…”

This study investigated the predictive validity of the ten Rorschach Performance Assessment System (R-PAS) variables from the Stress and Distress domain, by testing whether they predicted increased sympathetic reactivity to a mild, laboratory-induced stress, occurred one week after Rorschach administration. A relatively small student sample (N = 52) contributed to this research: During a first meeting (T1) participants were administered the Rorschach task according to R-PAS guidelines; about one week later (T2) their electrodermal activity (EDA) was recorded during exposure to a mild laboratory stress-inducing task. Based on literature indicating that exposure to stress tends to increase physiological vulnerability/reactivity to stressful situations, we anticipated that Stress and Distress R-PAS variables measured at T1 would positively correlate with increased sympathetic reactivity to stress at T2, as indicated by greater EDA changes from baseline to stress and recovery. Results partially confirmed our hypotheses: The (a) the mean of and (b) the majority of the Stress and Distress R-PAS variables were significantly correlated, in the expected direction, with medium and medium to large effect sizes.

“…However, it was first expressed by Vigouroux in 1879. Then the physiological and psychological researches began to be conducted [4,5]. Although it has been known for long years that the skin is electrically active, the relationship between the SSR and sweat glands in the skin was introduced by Tarchanoff [6].…”

“…In the 1970s and 1980s, it was termed as endosomatic when this response was recorded as electrical skin potentials, and as exosomatic when this response was recoded as a change in skin resistance against externally applied electrical current [3]. In the literature, it has been termed as electrodermal activity [4], electrodermal response [5], psychogalvanic reflex [10], galvanic skin response [36], peripheral autonomic surface potential [8], and sympathetic skin response most commonly [9]. In 1984, Shahani first used the name "sympathetic skin response" [9].…”

This article aims to introduce readers to a recent research topic, sympathetic skin response (SSR). The article provides information on the historical development of sympathetic response since the late 19th century. The article also includes information on the identification of naturally existed amplitude and latency values and classification based on these values, international measurement techniques with the studies conducted within the last hundred years, the factors effecting these measurements according to the studies conducted, and criteria used in the evaluation of the data obtained. In addition, information is given about the studies that have been made.
