The second analysis used an ANOVA approach (Penny and Henson, 2006) to identify brain regions whose activity is significantly modulated by the two factors manipulated in the experiment, the origin of the motion (motion capture, keyframe) and the characters (Dots, Ellipse, Jogger) used to render it, and the interaction between these factors. Cognitive sciences are starting to make use of such characters (Tarr and Warren, 2002) as stimuli (Pelphrey et al., 2003; Thompson et al., 2005; Schilbach et al., 2006) and when testing virtual reality therapy for social phobia (Klinger et al., 2005; Pertaub et al., 2001; Roy et al., 2003). : 0.06), Ellipse (0.06 ± 0.05) and Dots (0.21 ± 0.04) characters. No brain region was found to correlate with sensitivity at the thresholds used.

Activity is reported in regions that have repeatedly been associated with mentalizing [TPJ (Frith and Frith, 1999; Saxe and Kanwisher, 2003), ACC (Amodio and Frith, 2006) and PreC (Cavanna and Trimble, 2006)], which describes reasoning about the content of other individuals’ mental states.

This region has been repeatedly argued, in monkey (Oram and Perrett, 1996), humans (Puce et al., 2003) and computational simulations (Lange and Lappe, 2006), to be the site of integration of form and motion information coming from the ventral and dorsal streams of visual processing, respectively, during the perception of social signals such as actions or speech (Allison et al., 2000; Puce and Perrett, 2003).

Characters (F6,66 = 8.32, P < 0.001) and sessions (F3,33 = 6.14, P = 0.002) have a significant effect on sensitivity, but only the characters have an significant effect on the response bias (GG F6,66 = 16.29, P < 0.001).

More interestingly, the right inferior frontal and intraparietal sulcus clusters of activity negatively correlated with the response bias could be attributed to the involvement of the mirror system (Rizzolatti and Craighero, 2004). As illustrated in Figure 2A, the ratio of stimuli classified as biological depends mainly on the origin of the stimulus (motion capture or keyframe), but it is also influenced by the character used to render the motion. In each of the four experimental sessions, each of the seven characters (Figure 1A) was presented six times depicting motion capture and with keyframe stimuli. This implies that the response bias originates in normal visual perception mechanisms, and explains why even synthetic movements rendered with point-light displays are readily accepted as natural (Cutting, 1978). At the level of individual subjects, the bias reflects how natural a motion is perceived, irrespectively of the characters used to render the motion.

Paired t-tests on the response bias for the full characters identify two groups: differences between the response bias to the ellipse and the robot characters, on the one hand, and between the monster, clown and jogger characters on the other hand, are not significant, whereas all pairwise comparisons between characters from these two groups are significant (Figure 2C). We ensured verbally that they understood the meaning of the two different types of motions and the instruction before the onset of the first experimental session. Ten sets of motions and three graphical models [26 Dots (referred to as Dots), Ellipse and Jogger in Figure 1A] were selected for the fMRI experiment, while keeping the same randomization procedure.
