| Abstract |
The Dual Visuomotor Channel theory of reaching proposes that a reach-to-grasp act integrates a Reach, directed toward the extrinsic properties of the target (location), and a Grasp, directed toward the intrinsic properties of the target (size and shape). Previous studies of reach-to-grasp report that the Grasp is altered in pantomime tasks made from a starting position with digit 1 and digit 2 closed and proximal to the target. The present study extends the analysis of real versus pantomime reaching to a task that featured both a Reach and a Grasp, having a starting position with the hand open and proximal to the body. For a real reach, seated participants reached for a doughnut ball (food item) located on a pedestal at arms distance, with the intent of bringing the doughnut ball to the mouth for eating. Participants also made four pantomime reaches with: (1) the doughnut ball removed from the pedestal, (2) the doughnut ball and pedestal moved to the side of the reach location, (3) the doughnut ball and pedestal absent, and (4) the participants wearing vision-occluding glasses. There were two main findings. First, the presence of task-related cues, platform, doughnut ball, and room influenced the kinematics of the Reach and Grasp. Second, the compound structure of a real reach, in which flexion/extension of the arm featured in the Reach and flexion/extension of the digits featured in the Grasp are out of phase, changed in pantomime such that these features of Reach and Grasp became in phase. The results show that pantomime reaching is influenced not only by task-related percepts but also by central mechanisms ordinarily related to integrating the Reach and the Grasp. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 06 August 2016.
All research outputs
#20,336,685
of 22,881,964 outputs
Outputs from Experimental Brain Research
#2,918
of 3,234 outputs
Outputs of similar age
#318,270
of 364,031 outputs
Outputs of similar age from Experimental Brain Research
#50
of 61 outputs
Altmetric has tracked 22,881,964 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 3,234 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.0. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 364,031 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 61 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
