Abstract

Abstract Some individuals pick their skin excessively which induces skin lesions. These individuals with high severity of skin-picking (SOSP) usually experience their picking not as painful, although this behavior causes physical harm. This may point to lowered pain sensitivity in individuals with elevated SOSP. A total of 144 participants characterized by three different levels of self-reported SOSP received electrocutaneous pulses of different intensities to the skin surface of their left forearm. A mixed-model analysis of variance tested the effects of SOSP group (no/medium/high skin-picking severity) and stimulus intensity (6,16,26,36 mA) on participants’ ratings for perceived intensity/unpleasantness of stimuli and their own affective state (valence, arousal). Relative to participants who never pick their skin, the medium and high SOSP groups reported feeling more unpleasant and aroused during electrocutaneous stimulation. The three SOSP groups did not differ in the evaluation of the stimuli. It has to be noted that only a limited set of stimulation parameters (one location of stimulation; four stimulus intensities) were included. The present findings suggest that emotional responsivity to skin stimulation (but not pain sensitivity) is an important factor in understanding skin-picking behavior.

期刊介绍： One of the largest multidisciplinary open access journals serving the psychology community, Cogent Psychology provides a home for scientifically sound peer-reviewed research. Part of Taylor & Francis / Routledge, the journal provides authors with fast peer review and publication and, through open access publishing, endeavours to help authors share their knowledge with the world. Cogent Psychology particularly encourages interdisciplinary studies and also accepts replication studies and negative results. Cogent Psychology covers a broad range of topics and welcomes submissions in all areas of psychology, ranging from social psychology to neuroscience, and everything in between. Led by Editor-in-Chief Professor Peter Walla of Webster Private University, Austria, and supported by an expert editorial team from institutions across the globe, Cogent Psychology provides our authors with comprehensive and quality peer review. Rather than accepting manuscripts based on their level of importance or impact, editors assess manuscripts objectively, accepting valid, scientific research with sound rigorous methodology. Article-level metrics let the research speak for itself.
