The Mayman Form-Level Scoring Method: Scorer Reliability and Correlates of Form Level

A method of scoring the form level of Rorschach responses developed by Mayman (1962) was employed in a study of 100 twins and 95 of their parents. A method of training is described that led to generally adequate inter-scorer reliabilities. The relationship of mean form level to age, sex, and intellectual abilities is discussed, as are results relevant to the “heritability” of mean form level. It is concluded that mean form level is of complex determination and should be interpreted cautiously in developmental studies. It is argued that Mayman's highly differentiated approach to form level has unique value for qualitative analyses of Rorschach protocols.
