Jung studied the psychobiology of psychiatric illness, notably schizophrenia—at the time termed ‘dementia praecox’—at the Burgholzli Clinic in Zurich, then directed by Eugen Bleuler (Mo ller et al., 2002). Early on, he published laboratory studies of galvanic skin response in psychiatric illness and reported them in Brain (Peterson and Jung, 1907; see review by Compston, 2011), with follow-on studies appearing later that year in the Journal of Abnormal Psychology (Ricksher and Jung, 1907). His research still resonates today in the field of biological psychiatry, notably among 21st century studies of electrodermal activity (EDA)(Nilsson et al., 2015; Peterman et al., 2015). Peterson and Jung cited physiologist Ivan Tarchanoff (Ivane Tarkhnishvili in his native Georgian; Tsagareli, 2012) as the first to discover the effect of ‘strong emotion’(fear, fright, or joy) and ‘expectant attention or anticipation’on the galvanometer. They noted that in 1890 Tarchanoff posited that galvanic skin response was due to ‘a secretory current of electricity associated with the sweat-glands’; history has borne this position out. Peterson and Jung felt that Tarchanoff ‘was evidently unaware of the extraordinary value of the investigations he described in this brief paper’. Indeed, this proved to be the case when his experimental approach found its way to Europe, including the Zurich laboratories of Otto Veraguth in 1906 and of Carl Jung’s the following year.Most commentary on the historical importance of Peterson and Jung’s 1907 publication focuses on the galvanic skin response elicited by word association tasks. However, there were also extensive studies of responses elicited by salient auditory stimuli. Remarkably, Peterson and Jung included their original galvanic skin response data on these responses in their 1907 Brain report on schizophrenic cases and normal controls, making commentary on group differences, though without the quantitative analysis typically required by journals today. The diagnostic criteria used at the Burgholzli Clinic were not specified, but the authors delineated nosologic subtypes that had currency at the time. Their tables in their article organized these data in sufficient detail to permit post hoc analysis using modern statistical procedures. We have used up-to-date non-parametric statistical methods to analyse the raw data in their paper. Peterson and Jung recorded galvanic skin response using an array of potential alerting conditions, including ‘a loud whistle’(Series I) and ‘the fall of a weight with a very loud noise’(Series II). Though by today’s standards these conditions may sound quaint, in fact the stimuli used for eliciting electrodermal response closely resemble those used in modern studies. The investigators predicted longer ‘latent times’(latencies) among the patients compared to control subjects. Our statistical analyses have borne out this prediction. We applied the non-parametric Mann-Whitney U-test to contrast the ‘Dementia Praecox’patients (n= 8 for both series) against the ‘normal cases’(n= 5 for Series I, n= 8 for Series II/III) for latent times in seconds. Despite the fact that the sample sizes were modest, group comparisons yielded statistically significant findings. The contrast for the first series yielded a z-score of 1.74 and a U= 10, in
