Fung, M.T., Raine, A., Loeber, R., Lynam, D.R., Steinhauer, S.R., Venables, P.H. and Stouthamer-Loeber, M. (2005) Reduced electrodermal activity in psychopathy-prone adolescents. Journal of Abnormal Psychology, 114 (2). pp. 187-196. ISSN 0021-843XFull text not available from this repository.
This study tests the hypothesis that psychopathy-prone adolescents show reduced anticipatory skin conductance responding. Electrodermal activity was recorded while participants anticipated and responded to a 105dB signaled or unsignaled white-noise burst. Using an extreme groups design, the authors used Child Psychopathy Scale (D. R. Lynam, 1997) scores from a community sample of 335 male adolescents (age 16) to form control (n=65) and psychopathy-prone (n=65) groups. Significantly more psychopathy-prone participants were nonresponders in the signaled anticipatory (p=.014), signaled responsivity (p=.037), and unsignaled responsivity (p=.003) conditions compared with controls. Anticipatory hyporesponsivity of psychopathy-prone adolescents similar to the electrodermal hyporesponsivity found in psychopathic adults suggests that this autonomic impairment is present by adolescence and may predispose individuals to adult psychopathy.
