“…A correlation between the movement response and ability to inhibit movement suc-cessfully has been found by Meltzoff, Singer, and Korchin (1953), Singer and Spohn (1954), Singer and Herman (1954), and Singer, Wilensky, and McCraven (1956). Moreover, the fact that movement responses tend to be increased by motor inhibition tasks or by immobilizing or inhibiting conditions has been demonstrated by Singer, Meltzoff, and Goldman (1952), by Meltzoff, Singer, and Korchin (1953), by Goldman and Herman (1961), and by Neel (1960). Most of the effects found in these studies relate primarily to the human movement response, but the conditions in the study of Goldman and Herman influenced only the animal movement response significantly, while those in Neel's study affected inanimate movement most strikingly.…”
