The signer and the sign: cortical correlates of person identity and language processing from point-light displays.

Campbell R, Capek CM, Gazarian K, MacSweeney M, Woll B, David AS, McGuire PK, Brammer MJ - Neuropsychologia (2011)

Bottom Line: This activation may reflect the recruitment of information about person identity from the reduced display.Signer identification elicited greater activation than sign identification in (bilateral) inferior temporal gyri (BA 37/19), fusiform gyri (BA 37), middle and posterior portions of the middle temporal gyri (BAs 37 and 19), and superior temporal gyri (BA 22 and 42).Inferior temporal regions associated with the visual recognition of a person appear to be required during SL processing, for both carrier and content information.

Still images taken from video showing: (A) natural SL – one of the target signers producing the BSL sign DRESS (shown for illustration purposes; not presented in the experiment), (B) the same signer producing DRESS in point-light form and (C) an example of the motion baseline.

Mentions: The stimuli for this study were recorded from several different signers who produced a number of different signs that were then edited and shown as point-light displays (point-light SL). The baseline (motion control) condition reported here was a dynamic display which used the same spatial parameters as the points in the point-light display when the signer was at rest, but reconfigured to generate a figure in which the velocities of the trajectories of the points were similar to those in the biological motion display (see Fig. 1 and below for details). An additional baseline of the same number of static dots in an asymmetrically arranged configuration that could not be construed as a meaningful form was included, but activations in relation to this low-level baseline are not reported here.
