Differential-psychologische Untersuchungen zum Vigilanzverhalten

Zusammenfassung Mit Hilfe von Korrelationsmethoden wurden inter-individuelle Leistungsunterschiede in einer ein- und einer mehrflächigen Vigilanzaufgabe untersucht. In beiden Aufgaben korrelieren bestimmte Vigilanzscores mit Interferenzindikatoren im Stroop-Versuch. In der mehrflächigen Anordnung zeigte sich eine negative Korrelation zwischen der Entdeckungswahrscheinlichkeit und der Rate der falschen Alarme. Hinsichtlich der zeitlichen Merkmale der Vigilanzleistung ergab sich, daß die Vpn den geringsten Abfall der Entdeckungswahrscheinlichkeit erkennen lassen, die zu Beginn der Vigilanzaufgabe die Rate der falschen Alarme am stärksten reduzieren konnten. Die Ergebnisse wurden im Rahmen des detection-Modells interpretiert.

Experiments in individual differences of vigilance behavior

Summary This paper is concerned with individual differences of vigilance performance in a simple and a complex vigilance task. In both tasks certain aspects of vigilance behavior were correlated with interference in the Color Word Test by Stroop. In the complex vigilance task there was a negative correlation between the probabilities of signal detections and false alarms rates. With regard to the temporal characteristics of vigilance behavior it was found out that subjects with the least decrease of detection rate showed the greatest reduction of their false alarms rate to the beginning of the vigilance task. The results were discussed in the context of the detection model.

ATTITUDES OF SOUTH AFRICANS TOWARDS VARIOUS NATIONAL AND RACIAL GROUPS

Attitudes des Sud-Africains envers différents groupes nationaux et raciaux. En 1965, puis en 1966, un échantillon de 236 Sud-Africains blancs, ont jugé une série de 22 concepts qui désignaient principalement des groupes ethniques et diverses nationalités, à L'aide du Différenciateur Sémantique comprenant 20 paires d'adjectifs antonymes. Les résultats montrent que les attitudes à L'égard d'autres groupes ethniques sont relativement stables d'une année sur L'autre. Ils montrent, de plus, que c'est L'image du groupe en tant que tel qui détermine les attitudes des sujets à son égard, et non les différentes appellations, péjoratives ou laudatives, qui ont été utilisées pour le désigner. Une analyse factorielle a permis d'extraire trois facteurs: Image positive, Autoritatisme, Race non-blanche. Une seconde analyse factorielle, qui a porté sur les adjectifs utilisés dans le différenciateur sémantique, donne également trois facteurs: Activité, Valeur, Raisonnement, qui influencent la catégorisation des groupes ethniques visés. En conclusion, les AA. montrent que le Différenciateur Sémantique permet une analyse beaucoup plus fine que L'Echelle de Distance Sociale de Bogardus, des attitudes à L'égard des groupes raciaux et nationaux.     

Grading the ‘cultural literacy’ project

The essay examines the argument advanced by E.D. Hirsch, Jr., for instituting ‘cultural literacy’ as a fundamental priority of schools. A number of confusions and equivocations in Hirsch's reasoning are identified, and the propensity of his project to indoctrinate is exposed. Among the features of Hirsch's argument shown to be troubling are his shifting construal of ‘language’, his inconsistency about the requirements of cultural literacy, and his uncritical relation to traditional images of the American past and present. The upshot is to raise the question why Hirsch's project has elicited wide support and praise.     

Referenzsemantik in der Partnermodellierung

How can we explain that an assertion on something perceived can be understood in the same manner by somebody who cannot perceive that scene? This problem bases the interest in computational linguistics in how listener modeling could possibly be harmonized with reference semantics. Mental images substituting real perception appear as a way out. The architecture of the listener model has to be adapted to the creation and use of such pictorial data structures. Furthermore, the relation between the latter and a verbal (i. e., propositional) representation must be understood. The resulting architecture of a listener model with reference semantics can be employed to solve communicational problems from three general classes in a better way, as is demonstrated by an example implementation.     

Gender,psychological well-being and somatic cardiovascular risk factors

The purpose of this study is to determine associations between cardiovascular risk factors and subjective experience of psychological general well-being with special reference to gender-related differences. One hundred fifty white-collar workers in a car manufacturing plant in Sweden participated in a health care screening program. Subjective experience of psychological well-being was significantly correlated with cardiovascular risk factors among both men and women. There were, however, marked differences between the genders. For men, the following specific psychological variables were significantly correlated with cardiovascular risk factors: estimation of general health, anxiety, self-control and vitality. For women, more complex significant relationships between the two sets of variables were found. Moreover, the direction of the correlations differed between the genders. For example, men with cardiovascular risk factors, such as increased blood pressure, blood lipids and body mass index, reported significantly morepositive estimation of their general health. For women the relation was the opposite with a significantly positive correlation (p-0.004) between experience of good health and a low risk factor profile indicating the concordance between physiological and psychological parameters. Possible reasons for these sex differences are discussed.     

Future orientation of institutionalized and noninstitutionalized delinquents and nondelinquents

The present study is an analysis of the relationship between delinquency, institutionalization and future orientation, based on a social-learning theoretical framework. Two hundred and forty male adolescents (institutionalized and noninstitutionalized delinquents and nondelinquents) answered open and structured questions concerning their anticipations and evaluations of the future. The data were analysed by analyses of variance and t-tests and partly confirm the hypotheses: Delinquents structure their future in a less differentiated, less extended, and more internal way than nondelinquents. This was especially true for the institutionalized delinquents. However, delinquents structured their fears concerning their personal development more extensively than nondelinquents. Future orientation varied according to the length of institutionalization in different domains of life. These results do not support the dominant assumption of the literature that delinquents have an unrealistic future orientation. Rather, it is shown here that institutionalized delinquents anticipate rather negative future events which they expect to occur shortly after the time of their release. However, the present results have to be cautiously interpreted on account of the special selection of the sample and the rather short duration of institutionalization. Also, the method of a differentiated measurement of future orientation used here is hardly practiced in the literature though such a conceptualization as a multidimensional construct seems to be theoretically fruitful.     

Group therapy in an outpatient setting with borderline and narcissistic delinquents on probation

DSM-III criteria are used to describe the pathological manifestations of narcissistic and borderline disorders. The former gives rise to the Grandiose Self and the need to control the world. The delinquent act is an attempt to gain such control. The latter demonstrates ego splitting, primitive terror and rage stemming from the failure of the primary maternal introject. The attempt to compensate for inner turmoil and lack of object relatedness leads to delinquent acts. Citing three probationers referred by the court for group therapy, benefits and obstacles encountered in the use of outpatient group therapy are discussed as an approach to solving the unique problems presented by these delinquents.
