Rorschach movement and color responses and MMPI social extraversion and thinking introversion personality types.

Results of an analysis of MMPI profiles and Rorschach protocols scored by the Exner method for 100 psychiatric patients provided partial support for Rorschach's hypotheses that perceptions of color (FC, CF, and C) and movement (M) tap separate personality dimensions. First, the proportion of M responses on a protocol correlated significantly (p < .01) to thinking introversion as defined in terms of a subject's MMPI profile similarity to a prototypic MMPI profile with peak PtSc elevations. Second, the proportion of FC responses correlated negatively (p < .01) to social extraversion defined in terms of MMPI profile similarity to a prototypic MMPI profile with peak PdMa elevations. Hence, use of FC signified a socially reserved, controlled behavior. The findings regarding CF and C were inconclusive. Third, color and movement responses did not correlate significantly with somatization defined in terms of similarity to a prototypic MMPI profile with peak Hs, D, Hy elevations. Finally, the nonsignificant correlations of FC with M and with MMPI thinking introversion plus the nonsignificant correlation of M with color responses and MMPI social extroversion further supported the hypotheses that movement and color responses tap essentially unique personality dimensions.

P300 and introverted/extraverted personality types.

The P300 component of the event-related potential elicited with a two-tone auditory discrimination task and two-trial block replication procedure was obtained from 16 introverted and 16 extraverted undergraduate students. P300 demonstrated no overall significant effects for either the personality variable or the block variable. However, P300 amplitude to the target stimuli declined significantly between Block 1 and Block 2 for the extraverted subjects, but did not change across trial blocks for the introverted group. Female subjects tended to have larger P3 amplitudes than male subjects, but this factor did not interact with either the personality variable or the trial block variable. The results suggest that P3 amplitude habituates more rapidly for extraverts than for introverts.

Sex offenders: three personality types.

Analyzed by a Q-type factor analysis MMPI profiles of 92 sex offenders institutionalized for psychiatric evaluation, which yielded three basic MMPI profile types. Altogether 88 of the 92 Ss coult be categorized into one of three types characterized by profile peaks on F,Sc; Pd,MA; or D,PD. Analysis of background information, social history items, nature of present crime, primary diagnosis, and ward observations revealed significant differences among the types. Of particular interest was the finding that the primary diagnosis for 85% of the "F,Sc" MMPI type was "no mental disorder" in spite of the fact that this group showed significantly more disturbed behavior on the ward (anxiety, depression, suspicion, and manic excitement) and had uniquely degraded their victims. The fact that two-thirds of these persons who had F scores greater than or equal to 80 and 50% denied the crime may have inadvertently affected diagnostic decisions.
