Figure 3.

Mean values of peak grip aperture (A) and terminal grip aperture (B) in each condition. Differences between PV and PNV conditions for the 4 and 6-cm objects were found, whereas no difference of terminal grip aperture was noted between the PV and PNV conditions for any object size. PV, PNV, and RV indicate pantomime prehension with vision, pantomime prehension without vision, and real prehension with vision, respectively. Error bars indicate the standard errors of the values between participants.
