Abstract
|
Two important controls were exercised: the 20 criminals selected were chosen without any knowledge of their appearance; and a method of recording judgments was developed which made it possible to determine with some exactness how many of the correct responses should be attributed to cues arising from the photographs. The results from 175 students, who acted as judges, indicated that the average student can gain some cues from photographs which aid him slightly in making correct judgments. The number of correct judgments attributable to cues arising from the photographs is of negligible practical importance; but that the ability to gain such cues is real is attested by a high degree of statistical reliability.
