Turning to the recall of stamp head orientation and reverting to handedness in terms of reported hand preference in drawing, there was a significant effect of order of testing conditionalized upon handedness ([[Chi].
The proportions of left-handers, of right-handers tested first and right-handers tested second who correctly recalled stamp head orientation as facing to the left were 68.
There was in contrast again no significant difference between left-handers and right-handers in stamp head recall, with the magnitude of the left-handedness advantage numerically smaller in this experiment both for coin recall, 10.
He found the same pattern of results, with no significant effect of order on coin recall but significantly higher correct recall of the stamp head when this was tested first.
