Grounding and the luck objection to agent-causal libertarianism

Philosophical Studies - Many philosophers think there is a luck problem confronting libertarian models of free will. If free actions are undetermined, then it seems to be a matter of chance or luck...     

Relationships between MMPI codetypes and MAC scale elevations in adolescent psychiatric samples.

This study investigated the relationship between subjects' MacAndrew Alcoholism Scale (MAC) elevations and their placement in various codetype classifications. The sample consisted of 1,347 adolescents receiving psychiatric services in Missouri, Virginia, or Texas. The frequency of MAC scores greater than or equal to 24 and greater than or equal to 28 was evaluated, separately by gender, for single-scale and two-point codetypes, containing a minimum of at least 10 subjects. Marked differences occurred in the frequency of MAC scale elevations depending on the adolescent's codetype classification. MAC scores for both genders, for example, were most frequently elevated for the 4-9/9-4 codetype and more rarely elevated for the 2-3/3-2 codetype. Results are discussed in terms of potential measurement overlap which may occur between the MAC scale and several MMPI standard clinical scales, including 4, 6, and 9. It was also noted that the sensitivity and specificity of the MAC scale may vary in relation to subjects' clinical scale profile characteristics.     

Rorschach characteristics of mothers of incest victims

Investigated the Rorschach characteristics of 28 mothers of incest victims, using the Rorschach Comprehensive System. Their characteristics were compared to those from a control group of 28 women, matched with the target group for socioeconomic status (SES), age, education, marital status, and the presence of children. Chi-square, analysis of variance, and a stepwise linear discriminant function analysis were used to evaluate Rorschach differences between the control and target groups. Major findings indicate that mothers of incest victims demonstrated significantly greater weaknesses in reality testing, more frequent signs of depression, and greater interpersonal guardedness than control group mothers. Discriminant function analysis, based on scores from the schizophrenia index (SCZI), conventional form (chi + %), and texture responses (t), yielded an overall accurate classification rate of 87.5% for placement of women into the target and control group categories.     

MMPI response-set characteristics among adolescents

This study examined the Minnesota Multiphasic Personality Inventory (MPPI) profile characteristics for five different response sets in adolescent populations employing adolescent MMPI norms. In general, findings for "all-true" and "all-false" adolescent profiles were highly similar in shape and elevation to those reported in the adult literature (Graham, 1977; Lachar, 1974), whereas random profiles on adolescent norms differed substantially from adult-norm random profiles in shape but not elevation. The characteristics of "fake good" or "fake bad" response sets were investigated by the use of adolescent subjects in two settings. Ninety-four public high-school students were administered the MMPI with standard and "fake bad" instructions, and 24 adolescents in inpatient psychiatric treatment were administered the MMPI under standard and "fake good" instructions. The MMPI profiles generated by special instructional sets were analyzed in relation to the subject's age, sex, race, and actual MMPI profile features. Findings indicated that although sex and race effects were evident in normal adolescents' attempts to simulate psychopathology on the MMPI, teenagers generally produce profiles containing grossly exaggerated symptom patterns that are relatively easy to detect as invalid. In contrast, it was found that a substantial number of psychiatrically disturbed adolescents may effectively simulate normal profiles and that effectiveness in these attempts was related to greater age and lower actual MMPI T-score values on the Hs and Hy scales.
