The spiral aftereffect and personality

Reported duration of the spiral aftereffect was correlated with scores on the four scales of the Eysenck Personality Questionnaire and with the Psychoticism (P) scale from the unpublished PEN Inventory. There was a strong positive correlation between PEN P and duration. None of the other correlations approached statistical significance.     

Action verbal fluency normative data for the elderly

An emerging body of literature points to the prominent role of the frontal lobes in the retrieval of verbs, whereas production of common and proper nouns arguably is mediated primarily by posterior and anterior temporal regions, respectively. Although the majority of studies examining the neuroanatomic distinctions between verb and noun retrieval have relied on action naming tasks (naming depicted activities, e.g., running) as indicators of verb retrieval abilities, recent studies have utilized an action (verb) verbal fluency measure, the Action Fluency Test (AFT), to assess verb retrieval. Findings from these studies suggest that action fluency is sensitive to the integrity of fronto-subcortical neural circuitry and that it is a valid measure of executive and language functions. The AFT is an easily administered executive function measure, but no normative data for the AFT or other action fluency tasks has been published. This study was undertaken to provide initial AFT normative data for a sample of 145 healthy elderly subjects. As education is significantly correlated with AFT scores, the normative data are stratified by educational level.     

Toward international normative reference data for the comprehensive system

We build on the work of all the authors contributing to this Special Supplement by summarizing findings across their samples of data, and we also draw on samples published elsewhere. Using 21 samples of adult data from 17 countries we create a composite set of internationally-based reference means and standard deviations from which we compute T-scores for each sample. Figures illustrate how the scores in each sample are distributed and how the samples compare across variables in eight Rorschach Comprehensive System (CS; Exner, 2003) clusters. The adult samples from around the world are generally quite similar, and thus we encourage clinicians to integrate the composite international reference values into their clinical interpretation of protocols. However, the 31 child and adolescent samples from 5 countries produce unstable and often quite extreme values on many scores. Until the factors contributing to the variability among these samples are more fully understood, we discourage clinicians from using many CS scores to make nomothetic, score-based inferences about psychopathology in children and adolescents.     

Some normative data on mental health professionals' attitudes about racial minorities and women

Although codes of ethics of the mental health professions and the recently developed race- and gender-specific models of counseling and psychotherapy stipulate positive and accepting attitudes toward racial minorities and women, formal assessment of these attitudes has been hindered by the absence of appropriate measurement tools and generalizable data. This study provides some normative data by reporting responses of 705 psychologists and social workers to the Quick Discrimination Index, a psychometrically sound 23-item self-report measure previously administered to several different professional groups. Analysis indicated psychologists and social workers reported particularly positive attitudes toward racial minorities and women but expressed the same racial and sex contradictions, ambivalences, and vulnerabilities reported by the general public.
