VALIDITY GENERALIZATION RESULTS FOR LAW ENFORCEMENT OCCUPATIONS

The Schmidt-Hunter interactive validity generalization procedure was applied to validity data for cognitive abilities tests for law enforcement occupations. Both assumed artifact distributions, and distributions of artifacts constructed from information contained in the current sample of studies were used to test the hypothesis of situational specificity and to estimate validity generalizability. Results for studies using a criterion of performance in training programs showed that validities ranged from .41 to .71, and for four test types the hypothesis of situational specificity could be rejected using the 75% decision rule. For the remaining test types, validity was generalizable, based on 90% credibility values ranging from .37 to .71. Results for studies using a criterion of performance on the job indicated that the hypothesis of situational specificity was not tenable for three test types, which had validities between .17 and .31. For the remaining test types, estimated mean true validities ranged from .10 to .26 and were generalizable to a majority of situations. Results for both groups of studies were essentially identical for the two types of artifact distribution. Possible reasons for the apparently lower validities and lesser generalizability for job performance criteria are discussed, including possible low validity of the criterion (due to lack of opportunity by supervisors to observe behavior) and the potential role of noncognitive factors in the determination of law enforcement job success. Suggestions for specifically targeted additional research are made.     

INFLUENCE OF ASSESSMENT CENTER METHODS ON ASSESSORS'RATINGS

Recently a number of authors have argued persuasively that performance ratings are influenced to a large extent by the way the rater selects, organizes, stores, and recalls information. Although the influence of the rater's cognitive processes on the obtained ratings has been considered in the job-performance evaluation literature, this issue has not been considered in the assessment center literature. The purpose of the present study was to examine how assessment center methods affect the way assessors organize and process assessment center information and affect the ratings they make. Independent groups of assessors underwent one of two methods for evaluating candidates in an assessment center. Data indicated differences in the convergent and discriminant validities and differences in the factor structures of the ratings for the two methods. The pattern of results suggested that the two methods for evaluating assessment center candidates affected the way the assessors organized the assessment center information and affected the obtained ratings. Future research should consider assessment center methods and assessors as sources of variation in assessment center ratings.     

THE BIASING EFFECTS OF SUBORDINATE LIKEABLENESS ON LEADERS' RESPONSES TO POOR PERFORMERS: A LABORATORY AND A FIELD STUDY

A laboratory and a field study investigated the biasing effects of subordinate likableness on leaders' attributions for subordinate poor performance and their corrective actions toward subordinates. In the laboratory study, 96 undergraduate students served as leaders and were presented with a vignette describing an incident of poor performance committed by either a liked or a disliked subordinate. Leaders made attributions for the poor performance and then rated the appropriateness of a series of corrective actions. Analyses revealed that leaders made similar attributions for the poor performance of liked and disliked subordinates, but were more inclined to punish a disliked subordinate than a liked subordinate. A second study replicated these findings with 98 leaders in an actual organization. Implications of the results for disciplinary policies are discussed.     

Study instrument for psychopathology in computer-assisted analysis of findings (Structured Psychopathologic Detection System)

With the Structured Psychopathological Evaluation-System (SPES) an instrument existed for employment of objective criteria. This study was designed to present an evaluation system based on new scientific results, that is applying on the strength of a reduced catalogue of symptoms (94 compared with 198 Items at SPES-A) to clinical routine. Additional findings differentiated by this system be able to classify by the help of an operational decision system.     

EEG findings as a principle of military medicine disability evaluation in conditions following craniocerebral injuries

295 expert opinans of the NVA (National People's Army) in conditions after craniocerebral traumas for which an EEG findings was present were subjected to an retrospective analysis to determine the importance of EEG for export opinion. In 59.3% of cases EEG was significant for expert opinion, but was of prime importance only in 1.3%. In 161 expert opinions the total damage of the body was determined. This gave the possibility of a statistical correlation of individual EEG findings with the extent of the body damage. Mean percentage values of the individual degrees of severity of EEG changes could be calculated on the basis of these data. The great importance of EEG for military medical opinion could also be confirmed in comparison with 8 other clinical data and findings.     

Arthur Kronfeld (1886-1941)--a psychiatrist in the service of psychotherapy

The psychotherapeutic life-work of psychiatrist Arthur Kronfeld has almost fallen into oblivion. Against the background of the 100th anniversary of his birth the author traces Kronfeld's psychotherapeutic career, pointing out his activity at the Berliner "Institute of Sexual Research" under Magnus Hirschfeld, and his psychotherapeutic concept--the psychagogic guidance of the patient--and its connection with the individual psychology of Alfred Adler. Kronfeld translated his theoretical positions into activities directed towards socialization and the teachability of psychotherapy which are still worthy of note by those engaged in the field.     

Hysteria and psychosis

The relationship between endogenous-psychotic and hysterical behavior is presented in this paper on the basis of typical patients' accounts. Various patterns of behavior are revealed: chronic hysterical psychotic syndromes, acute hysterical psychotic syndromes, hysterical exalted psychotic episodes, simulated hysterical psychotic syndromes, hysterical behavior in the attempt to cope with psychosis, and pseudohysterical behavior in endogenous psychoses. The specific aspects of the doctor-patient relationship in the case of these patients are described.     

Stomatologic studies in schizophrenic patients--contributions to the problem of medical and social integration of psychiatric patients

Stomatological examination was carried out on 173 patients with schizophrenia (IKK-Nr. 295). It was observed that this group of patients showed a diminished dental and oral care in comparison to the average population of the same region. The close cooperation of dentists with the institutions for chronic patients will be as prophylactic measure in favour of the patients encouraged.     

Results of neurophysiologic studies in ophthalmic migraine

The influence in 8 of our patients with ophthalmic migraine of photic driving with sine-like flashing lights on EEG background activity was checked and the visually evoked potentials following the application of diffused simple light stimuli were analyzed using the recovery cycle technique. The results indicate a slightly increased tonic activity of the structures of the mesencephalic formatio reticularis, such as may be produced by slight functional disturbances. Some vegetative secondary symptoms of migraine attacks and some of the changes in EEG observed in patients with ophthalmic migraine are explicable by such an abnormality.
