Action Emulation between Canonical Models

In this paper we investigate Kripke models, used to model knowledge or belief in a static situation, and action models, used to model communicative actions that change this knowledge or belief. The appropriate notion for structural equivalence between modal structures such as Kripke models is bisimulation: Kripke models that are bisimilar are modally equivalent. We would like to find a structural relation that can play the same role for the action models that play a prominent role in information updating. Two action models are equivalent if they yield the same results when updating Kripke models. More precisely, two action models are equivalent if it holds for all Kripke models that the result of updating with one action model is bisimilar to the result of updating with the other action model. We propose a new notion of action emulation that characterizes the structural equivalence of the important class of canonical action models. Since every action model has an equivalent canonical action model, this gives a method to decide the equivalence of any pair of action models. We also give a partial result that holds for the class of all action models. Our results extend the work in van Eijck et al. (Synthese 185(1):131–151, 2012).     

The effect of cue Relevance,Ambiguity, and self-reported hostility on tat responses

The interaction of cue relevance and ambiguity was studied. Ss high or low in self-reported hostility were administered 8 T A T cards, half of which were high in hostility cue relevance, half low. Half of each subset, in turn, was high in ambiguity, half low. Highly relevant cards tended to elicit more aggressive content than low relevant cards, and stories to ambiguous cards tended to contain more aggressive themes than unambiguous ones, independent of hostility relevance. Hostile Ss tended to be best discriminated from non-hostile Ss on highly relevant cards, where they responded with more aggressive themes. Results were contrasted with previous findings and it was concluded that consistent with findings where hostility is defined by observation or arousal, highly relevant cues are most sensitive to hostility level. While greater expression of negative content, increments in ambiguity did not add to the sensitivity of the stimuli.     

A Note on the Stability of TAT Interjudge and Intrajudge Ambiguity Scores

The stability of TAT ambiguity values, based either on interjudge, or intrajudge response variability, was investigated. Interjudge variability was estimated from dispersion of the first response emitted to each stimulus; intrajudge variability utilized multiple associations by Ss. Multiple association yielded highly stable values in comparisons over time, and neither method resulted in stability across S samples. It was concluded that the definition of ambiguity must include intrajudge variability in order to achieve a reliable ordering of stimuli for a given respondent.     

The Inventory of Children's Individual Differences: Development and Validation of a Short Version

The development of programmed, actuarial interpretation of personality tests, especially the MMPI, is discussed. The presentation seeks to present a synoptic overview of the topic, including its more important trends, apparent present status, and possible consequences. Several commercially available systems are described, and an example of the output of each of three of them, in interpreting the same MMPI protocol, is presented for comparative illustration.     

Empirical Correlates of the MMPI–2 Restructured Clinical (RC) Scales in Psychiatric Inpatients

We identified empirical correlates of the MMPI–2 Restructured Clinical (RC) scales in 1,872 male and 498 female psychiatric inpatients drawn from 2 large tertiary care medical centers. We generated clinical criteria from a systematic review of the patients' intake and discharge medical records. We report zero order correlations between RC scales and clinical criteria and relative risk ratios for dichotomous variables. We found the RC scales to be correlated with conceptually relevant criteria such that for each scale, we identified significant increases in the risk for a variety of emotional, cognitive, and behavioral problems among individuals whose T score exceed 64.     

Development and Validation of a Dutch Translation of the Big Five Inventory (BFI)

The MMPI profiles of 74 low back pain patients who had previously been classified as "functional," "organic," or "mixed" were sorted into six profile groups. The six profile groups were those used by Pichot, Perse, Lekeous, Dureau, Perez, and Rychewaert (1972); denial, "conversion V" without defensiveness, "conversion V" with defensiveness, depressed/anxious, psychotic and normal. Results indicate that all six profile types are welt represented in the low back pain group. Evidence is also presented which shows that each of the pathological MMPI profile types examined across "functional," "organic," and "mixed" classification is significantly more elevated than a normal profile group on two scales (Lb, DOR) designed to measure functional aspects of pain. Pathological MMPI profile groups did not differ significantly from each other on the "functional," pain scales. The data presented in this study point to the relationship of various forms of psychopathology with "functional pain." The findings of this stud v would not support a homogeneous "pain personality" for low back pain patients. However, combined "conversion V" profiles accounted for 58% of the "functional" group, 45% of the "mixed" group and 35% of the "organic" group.     

Associations Between Symptom Validity Test Failure and Scores on the MMPI–2–RF Validity and Substantive Scales

Existing measures of approval motivation attempt to assess this dimension of personality indirectly through evaluation of socially desirable response tendencies. The Martin-Larsen Approval Motivation (MLAM) Scale takes a more direct approach by focusing on individual differences in need for social approval. Since the original version of the MLAM scale is subject to acquiescence response bias, fully balanced and partially balanced scales were created to minimize this response style. Results indicated that the revised measures arc equivalent to the original version and that balancing affects the magnitude but not the pattern of correlates with other scales. Comparisons with the Marlowe-Crowne Social Desirability (MCSD) Scale revealed a divergent pattern of correlates with several measures of personality suggesting a basic difference between the MLAM and MCSD in their conceptualization of approval motivation.     

An Examination of Triarchic Psychopathy Constructs in Female Offenders

This study sought to expand scientific knowledge on psychopathic personality traits in female offenders by evaluating the relationship between MMPI–2–RF triarchic scales and self-reported external variables in a sample of 205 female offenders. Results indicated that boldness was inversely related to internalizing dysfunction, including suicidal behavior, psychosis, youth conduct problems, problems stemming from alcohol use, and a history of outpatient mental health treatment. Meanness was positively related to internalizing dysfunction as well as youth conduct problems, anger, prison disciplinary reports, and psychosis. Disinhibition was associated with a history of abuse in childhood, suicidal behavior, internalizing dysfunction, problems associated with alcohol and drug use, family history of mental illness, prison disciplinary reports for violence, number of previous criminal charges, and anger. Consistent with views of psychopathy as a configural condition, interactive effects of boldness with disinhibition and meanness were observed for multiple key external variables (e.g., conduct problems, substance use, nonsuicidal self-injurious behavior). This study provides further evidence for the triarchic conceptualization of psychopathy in female offenders and lends additional support for the validity of MMPI–2–RF triarchic psychopathy scales.
