* means significant at the .05 level (2-tailed); ** means significant at .01 level (2-tailed).
Note: MD = Mean Difference (personality trait minus physical characteristic); SE = Std. Error. The left panel for negative personality and physical words and the right panel for positive personality and physical words.
