The authors regret an error in experiment 1 of this article and have provided the following explanation to correct the error:
Due to experimental error, in one of the subsets, one stimulus (left-hand biological no-pain stimulus in the axe scenario) was omitted, and instead, a different stimulus (right-hand biological pain stimulus in the axe scenario) was erroneously included twice. Thus, participants (N=13) who were presented with this particular subset rated 39 instead of 40 unique stimuli. Although the explicit pain ratings for this stimulus are missing, the equivalent stimulus presented with the right-hand was included in the same subset and was, thus, rated by the same participants. Analysis of the data for all other scenarios indicates no significant effect of laterality (left versus right limb) on pain ratings.
The final paragraph on page 3 was corrected as follows:
Mean painfulness ratings were calculated for each participant for each condition and are displayed in Table 1. These were subjected to repeated-measures ANOVA with factors of animacy (biological, non-biological) and pain (pain, no-pain). Main effects of both animacy (F1,49=205.24, p<.001, ηp2=.807), and pain (F1,49=124.95, p<.001, ηp2=.718), were observed, with biological stimuli producing higher painfulness ratings than non-biological stimuli, and pain trials higher ratings than no-pain trials. There was, however, a significant interaction between animacy and pain (F1,49=136.20, p<.001, ηp2=.735), whereby the effect of pain on the painfulness ratings was greater for biological than non-biological stimuli, although the simple effect of pain was present for both biological (t49=12.79, p<.001, dz=1.81, Hedges’ gav=1.87) and non-biological (t49=5.46, p<.001, dz=0.77, Hedges’ gav=0.72) stimuli.
