J. L. McCary, in the form of a hypothetical trial transcript formed from transcripts of three actual court cases, reports nearly the entire range of problems the psychologist as a witness may encounter. This chapter begins with the clinical psychologist as a court witness as revealed in the personal experiences reported in the American Psychologist with a single listing of references to the "case histories" as well as to the legal references scattered unsystematically in this journal. Only in the case reported by N. H. Eisen was the psychologist barred from testifying as an expert witness, and since his testimony was then as a layman he could not report on the defendant's responses to psychological tests. Psychologists reporting experiences should take care to give reference to courts, dates, case number, so that specific incidents may be traced to obtain additional information.
