Abstract
We studied the skin conductance and heart rate responses in two different racial groups when intra- and inter-racial pain was observed. Thirty-two white (16) and black (16) subjects were required to passively observe a movie (1.8 s) where a black or white hand appeared and was penetrated by a needle (black and white pain conditions) or touched by a cotton stick (black and white touch conditions). A total of three sessions of 16 pseudo-randomized movie trials were presented. Skin conductance response (SCR) and heart rate (HR) were simultaneously recorded during the experiment. For each measured variable, a two-way repeated measures analyses of variance (ANOVA) revealed a main effect of condition (black hand pain, white hand pain, black hand touch and white hand touch) [SCR: F(3,90) = 4.33, p = 0.0067; HR: F(3,90) = 3.36, p = 0.022] but not of race (black vs white) [SCR: F(1,30) = 1.74, p = 0.20; HRI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
