... Casasanto and colleagues studied how natural right-handers think about good and bad when their right hand is handicapped, either due to brain injury or something much less extreme: wearing a ski glove. Stroke patients completed a task that reveals implicit associations between space and goodness in healthy participants. Patients who had lost the use of their left hand showed the usual right-is-good pattern. But patients who lost the use of their right hand following damage to the left-hemisphere of the brain associated good with left, like natural left-handers.
The same pattern was found in healthy university students who performed a motor fluency task while wearing a bulky glove on either their left hand (which preserved their right-handedness) or on their right hand, which turned them temporarily into left-handers. After about 12 minutes of lopsided motor experience, the right-gloved participants' judgments on an unrelated task showed a good-is-left bias, like natural left-handers.
'People generally think their judgments are rational, and their concepts are stable,' says Casasanto. 'But if wearing a glove for a few minutes can reverse people's usual judgments about what's good and bad, perhaps the mind is more malleable than we thought.'
