Grant proposal: circle drawing as objective handedness test
Description
The research being proposed would develop an objective test for handedness analyzing circle-drawing movements performed with the dominant arm versus non-dominant arm. Handedness is a unique and exceptional characteristic of human beings which impacts society on an individual basis that has far-reaching influence. Its correlation and possible causation has been studied and implied in everything from mental disorders (Deep-Soboslay et al. 2010) to advanced biological processes (Driscoll, Kei, & McPherson, 2002). Despite the importance of handedness, there are many faults surrounding the widely used methods for determining and classifying handedness. The most common of these, the Edinburgh Handedness Inventory, especially suffers from reporter bias, possibly confusing categories and instructions, and underestimating ambidextrous or mixed handedness. Research done by R.L. Sainburg of Penn State and N. Dounskaia of Arizona State University points to a possible method of measuring handedness. The findings of these studies show show that the dominant arm to perform better in drawing movements than the non-dominant arm. It is proposed that an objective test could be developed for handedness using circle-drawing tasks. A participant would draw circles with both arms, these movements would be analyzed to show which arm was dominant by showing which arm made the more perfect circle. By developing an objective test, handedness could be more properly classified and assessed, helping aid research and understanding in how handedness affects humans.
