title: Mirror, mirror on the wall ... comments on the chimeric face task used by Roszkowski and Snelbecker (1982).
abstract: A critique is presented of the chimeric face task used as a measure of cerebral laterality by M. J. Roszkowski and G. E. Snelbecker (1982, Brain and Cognition, 1, 404-409). Problems arise because the faces used are not true mirror images of each other, but in fact differ in facial details. Data are presented to illustrate that the earlier results are not caused by cerebral laterality but by the fact that the two drawings are not equally happy--even when placed in the same left-right orientation.
