The Pen Is Not Always Mightier: Different Ways of Measuring Handedness With the Edinburgh Handedness Inventory Yield Different Handedness Conclusions.

摘要: Although consistency of handedness (the strength dominant hand preference) is increasingly recognized as an important individual difference, there are questions about how to best measure it. A recent meta-analysis showed that researchers have often failed report details responses and response formats test items. In addition measuring direction (i.e., left versus right handedness), can be utility dichotomizing the Edinburgh Handedness Inventory (EHI) into consistent inconsistent handedness, despite controversy over means doing so. this study, we performed a discriminant function analysis EHI items determine which predicted direction. same accounted for most variance both dependent measures, writing drawing were strongest predictors combing opening jars consistency. As different on these dimensions, discuss implications relevant dimensions biological environmental theories basis future research.
