Figure 2. Sample trial.

(a) Complete trial from just before the onset (indicated by the illumination of the Perspex plate above the object) until that object weighing 165 g was replaced and the hand returned to the starting position. Arrows labelled Digit contact, Load phase onset, etc, mark some of many ‘events’ extracted from all single trials (cf. Table 1). (b) The window marked by a yellow rectangle in (a) shown on an expanded time scale.
