Prototype Personality Diagnosis in Clinical Practice: A Viable Alternative for DSM-V and ICD-11

Several studies suggest that a prototype matching approach yields diagnoses of comparable validity to the more complex diagnostic algorithms outlined in DSM-IV. Furthermore, clinicians prefer prototype diagnosis of personality disorders (PDs) to the current categorical diagnostic system or alternative dimensional methods. An important extension of this work is to investigate the degree to which clinicians are able to make prototype diagnoses reliably. The aim of this study is to assess the inter-rater reliability of a prototype matching approach to personality diagnosis in clinical practice. Using prototypes derived empirically in prior research, outpatient clinicians diagnosed patients' personality after an initial evaluation period. External evaluators independently diagnosed the same patients after watching videotapes of the same clinical hours. Inter-rater reliability for prototype diagnosis was high, with a median r = .72. Cross-correlations between disorders were low, with a median r = .01. Clinicians and clinically trained independent observers can assess complex personality constellations with high reliability using a simple prototype matching procedure, even with prototypes that are relatively unfamiliar to them. In light of its demonstrated reliability, efficiency, and versatility, prototype diagnosis appears to be a viable system for DSM-V and ICD-11 with exceptional utility for research and clinical practice.     

TWO MEASURES OF PREFERENCE DURING FORCED-CHOICE ASSESSMENTS

A forced-choice preference assessment was conducted in which two dependent measures were used to select preferred stimuli: (a) approach responding and (b) latency to the first aberrant response. Stimuli identified as preferred based on both dependent measures were then evaluated during treatment. The results suggested that latency may be a useful measure in the selection of preferred stimuli during forced-choice assessments.     

Intergroup Ratio and the Contact Hypothesis1

This study assessed whether contact between members of 2 social groups generalized to contact in another setting, as well as influenced their intercultural knowledge and acceptance. Subjects were 244 international (mainly ethnic Chinese) and Anglo-Australian students living in 3 student residence halls, with each group comprising a numerical majority, equal proportion, and a numerical minority in one of the residential halls. As anticipated, group ratio exerted a systematic effect on the amount of intercultural contact, with most contact by members of a numerical minority, regardless of student group. Importantly, the pattern of residence-hall contact tended to generalize to the wider university environment and to influence intercultural knowledge and acceptance. However, contact was not unqualified in its effects, particularly in relation to members of the cultural majority.     

Working memory capacity predicts search accuracy for novel as well as repeated targets

Visual search behaviour is guided by mental representations of targets that direct attention toward relevant features in the environment. Electrophysiological data suggests these target templates are maintained by visual working memory during search for novel targets and rapidly transfer to long term memory with target repetition. If this account is correct, an individual’s working memory capacity should be more predictive of search performance for novel targets than repeated targets. Across six experiments, we tested this hypothesis using both single (Experiments 5 and 6) and multiple (Experiments 1–4) target search tasks with three different types of stimuli (real world objects, letters, and triple conjunction shapes). Each target set was repeated for six consecutive trials. In addition, we estimated visual working memory capacity using a change detection working memory task. Overall, working memory capacity did not predict response time or efficiency in the visual search task. However, working memory capacity was equally predictive of search accuracy for both novel and repeated targets. These results suggest that working memory requirements do not substantially differ between novel and repeated target search, and working memory capacity may continue to play an important role in the encoding or maintenance of target representations after they are presumed to be in long term memory.     

The effects of a wisdom intervention in a Christian congregation*

Psychological research on the topic of wisdom is limited in its incorporation of religion and spirituality. This gap in psychological literature may serve to limit a thorough understanding of wisdom. Positive psychology may allow for some rapprochement in wisdom and spirituality. In collaboration with leaders of a local Friends (Quaker) congregation, two studies investigated the effects of a spiritually informed wisdom intervention delivered in the context of a faith community. Participants for Study 1 consisted of 27 young adults (24 completed both the pre and post questionnaire) and a comparison group consisting of 32 young adults. The intervention was designed to increase participants’ abilities in cognitive, affective and moral domains. Significant group by time interaction effects were found among measurements of practical wisdom, post-formal thinking and subjective well-being, with those in the experimental group showing changes in the expected direction. Study 2 involved qualitative analyses of interviews with 15 of the wisdom participants regarding their changing views of wisdom. Themes emerging from the interviews included a multiple-perspectives view of wisdom, the relational nature of learning wisdom, the importance of taking a reflective perspective, and congruence between what one knows and how one lives. Implications for studying wisdom alongside religion and spirituality are considered.     

Ethnophaulisms for ethnic immigrant groups: the contributions of group size and familiarity

An archival analysis was conducted on the ethnophaulisms for ethnic immigrant groups as a function of the size and the familiarity of those groups. Cognitive representation was operationalized as the degree of complexity in, and the valence of, the ethnophaulisms applied to ethnic immigrant groups in the United States during each of 15 consecutive 10‐year time periods. Group size was operationalized as the number of first‐generation persons in these ethnic groups during each of these same 15 10‐year time periods. Familiarity was operationalized in terms of the number of times each ethnic immigrant group was mentioned in social histories and popular songs for each of these same 15 10‐year time periods. Ethnophaulisms for smaller groups tended to be less complex and more negative and ethnophaulisms for less familiar groups tended to be less complex and more negative. Analyses delineate the interrelations between ethnic immigrant group size, ethnic immigrant group familiarity, and the cognitive representations of these groups. The implications of these results for research on intergroup perceptions are discussed. Copyright © 2001 John Wiley & Sons, Ltd.     

Criterion-referenced and norm-referenced assessment of minority group children

A variety of problems have been experienced with psychological assessment of minority children. Traditional norm-referenced measurement has repeatedly received criticism concerning cultural unfairness or bias. Responses to such accusations primarily have been in the form of new instrumentation aimed at attaining a culture fair assessment. Little response has been evident from a conceptual standpoint addressing the issues of purpose and use of test results Although many have turned to criterion-referenced measurement as an answer to the problems of norm-referenced evaluation, cultural bias is not necessarily avoided in this framework either. Issues of who determines criteria and what those criteria include must be addressed if criterion-referenced measurement is to meet adequately the challenge of multicultural evaluation.     

Exposure to Spatial Cues Facilitates Visual Discrimination but Not Spatial Guidance

The performance in a radial-arm maze of two groups of rats with restricted access to extra-maze visual cues was studied. One group received extensive exposure to the visual environment of the maze, whereas the second group was never exposed to the environment, aside from their experience in the maze itself. Spatial exposure resulted in a slightly improved ability to discriminate between previously visited and unvisited spatial locations, which can be explained on the basis of general perceptual learning processes. However, there was no evidence that spatial exposure resulted in control of choices by the spatial relations among the maze locations. These results are discussed in terms of theories of spatial learning which appeal to perceptual learning and cognitive mapping.
