Block and psychoticism.

Argues that J. P. Block's (1977) criticisms of the Eysenck and Eysenck Adult Psychoticism Scale are one-sided and do not take into account all the evidence. It is also suggested that Block's criticisms center on a function not at all envisaged for the scale, that is, the discrimination of psychotics from normals and other nonpsychotic groups. The scale was constructed to measure the underlying personality dimensions of psychoticism in nonclinical groups; therefore, the number of false positives and negatives in comparing normal and psychotic groups is largely irrelevant.
