His hands held tools and he made decisions.
In the following analyses, it is important to note that, in testing the visual and tool tip position effects, the contribution of the hand that holds the tool is effectively ignored - these analyses were performed by collapsing across the variable hand, and in any case the BOLD signal changes of interest were independent of which hand held the tool (data reviewed but not shown).
In an additional analysis, we searched for brain regions which showed a significant interaction between the positions of the visual distractor and the tip of the tool, both for the two hands (experiments) together, for each hand (experiment) separately, and for the three-way interaction including the factor of which hand held the tool (experiment).
These congruency effects were slightly larger in general when the tool was held on the right, as compared to on the left, side of visual fixation (p = .013), irrespective of which hand held the tool, and the location of the visual distractor.
Tissue slice preparation is illustrated in figure 1. Tissue cores (5 mm in diameter) were prepared under a sterile hood using a hand held coring tool.
We instructed the healthy participants in our experiments explicitly to ignore the visual distractors, and to pay attention only, and to respond only, to the type of vibrotactile target presented at the tip of the tool, and felt by the hand holding the tool.
Carve away the design using a hand held mini power tool with a fine bit.
Participants were presented with 2-frame sequences of tool actions (see Fig. 1 for examples), consisting of a hand holding a tool (e.g., a key) and a goal object (e.g., a keyhole).
The optimal strategy for correct task performance might therefore have been to close one's eyes and to pay attention to the vibrotactile stimuli perceived by the hand holding the tool.
Denatured PCR products were printed in duplicate on Zetaprobe membranes (BioRad, Hercules, CA) using hand held 96-pin replicating tool (V&P Scientific, San Diego, CA).
The demand drivers are many, but smaller computers and hand held devices require laser based tools that can enable customers to achieve miniaturization, complexity and better manufacturing yields.
