onal encouragement, public announcement of records, etc., Binet -andVaschide found that the average grip was increased about 3 kg.,or so much that the left hand surpassed the previous record ofthe right hand niade without such incitement. Similarly,Schuyten (13) found that ennui, or loss of interest in succes-sive tests, is sufficient to obscure the fatigue effect of a schoolsession. (7) Dependence on social status. Schuyten concludes thatthe children of well-to-do parents are stronger than the childrenof poor parents, and Hrdlicka found asylum children belowaverage on account of their poorer circumstances and unfavor-able environment in early childhood.

MacDooald found no correla-tion between strength of hand and mental ability: the indica-tions that, on the contrary, dull children tended to surpassaverage and bright children in this capacity are interpreted byhim as due to the presence in the dull groups of numerous chil-dren from the poorer classes of the community, who tend, asjust stated above, to be stronger in grip on account of manualactivity.
