Computer content analysis of the Schreber case.

The text of Schreber's Memoirs of My Nervous Illness was analyzed by computer at the level of the individual word. These words then were grouped into 17 rational categories, and the categories were checked for reliability. The contents of Schreber's work then were compared with three other documents. In general, the Memoirs showed much greater delusional content than the other documents. Interestingly, sexual matters did not appear to be Schreber's principal problem at this atomistic level.

Spectral analysis of interviews conducted by Rogers and Ellis.

Recordings of famous therapeutic interviews were digitized by computer, then subjected to time-series analysis. Spectrograms produced by the same therapist seeing different patients were similar, while spectrograms of different therapists were rather divergent. Further analyses were carried out on the digitized data. The techniques used offer promise as an objective way of quantifying therapeutic interview data.

ELIZA as a "therapeutic" tool.

Allowed 70 undergraduate students to interact for 44 minutes with ELIZA--a computer simulation of psychotherapy. Their responses during the first and second halves of the session were compared, and several differences were found. Removing the effect of the simple volume of responses (using the analysis of covariance) did not change the significance of many of the differences.

Reassessment of factor solution of Halstead's Matrix.

Halstead's correlational matrix of 13 neuropsychological tests was reanalyzed with the objective of obtaining a more neuropsychologically meaningful solution. The emphasis was on solving for different numbers of factors (three and five). The three-factor solution supported and perhaps refined two of Halstead's original factors (P and A). The third factor loadings resulted in a considerably different concept that Halstead's D. The three factors (psychological vigilance, abstraction, and perception and memory for incidental stimuli) may be an essential factor pattern in recovery from head traumas. It was concluded that the investigator should not a priori be committed to a structure involving a particular number of factors. Experimentation with factor number or method would allow evaluation of the best psychological fit to the data.

Evaluation of a content-analysis system for therapeutic interviews.

The Zimmer and Cowles system for content analysis was tried out on psychotherapeutic sessions and on interviews with disturbed patients. It was found that the system indeed did seem to pick up improvement in psychotherapy, and to a lesser degree, differences in speech behavior between patients with radically differing pathologies. It also was concluded that the computer program for the content analysis system is not easily portable, but a SNOBOL equivalent is made available.

A new automated interpretation system for the 16PF.

A new computerized interpretation system for the 16PF is described. This system is based on the novel concept of attempting to simulate directly the diagnostic report-writing capabilities of a single clinician. Certain considerations regarding the problem of validity in respect to this area are brought up, and the general operation of the system is outlined.
