Radikaler Konstruktivismus und Konstruktionismus

Both radical constructivism and constructionism are naturalized approaches to epistemology. They try to fertilize results from biology and psychology for epistemological aims. They both refuse epistemological realism as unsustainable metaphysics. This raises the problem of the range of the naturalistic approach to epistemology. Constructivism, in both forms, turns out to be untenable because it runs in an aporia: it must borrow from realism either, or it must qualify its own position as a metaphysical one. But therewith, constructivism would be blamed to be metaphysical itself.     

Visually controlled matching of pattern movement

Utrecht Biophysics Research Institute, Rijksuniversiteit Utrecht, Utrecht, The Netherlands Subjects were asked to match the speeds of two moving random-dot patterns seen through circular apertures. The speed of one pattern that moved horizontally toward the right of a computer screen changed continuously. The speed of this pattern represented the target. It was to be matched with the speed of the second pattern, which moved in the opposite direction. The subject controlled the speed of the second pattern by means of an isometric joystick. The distance between the apertures on the screen as well as the subject’s distance from the screen served as experimental parameters. In this way, the effects of both spatialand temporal transients of pattern speed on human tracking performance were studied. To avoid anticipation by the subject, the amplitude and the frequency of the target pattern speed changed pseudorandomly. The accuracy with which the subject performed the matching task was influenced by the mean pattern speed and the parameters of the visual field. Within lower velocity ranges, the subject’s sensitivity to the instantaneous speed differences varied according to Weber’s law. The cross-correlation of the velocity time courses decreased when the mean speed of the target pattern was increased. Two stimulus parameters had a strong influence on the modulation of the correlation value: (1) the angular size of the stimulus on the retina and (2) the retinal eccentricity of the stimulus.     

Initial experiences with cognitive therapy of schizophrenic patients

Based on earlier experiences of various groups of authors, we developed and modified a programme of cognitive therapy for schizophrenic patients. The aim of the application of the therapeutic programme to subacute patients was to decrease subjectively perceptible basic disorders and to improve the functions of performance. The present results and experiences with 4 groups consisting of a total of 31 patients encourage us to continue applying cognitive procedures of therapy. Problems of the ascertainment of measuring values and fundamental questions of therapeutic efficacy are discussed.     

The psychoanalytic narrative. On the problem of objectivity

The author seeks to develop a narrative conceptualization of psychoanalytic treatment. Its nucleus is the causal explanation of life history and illness. She criticizes the hermeneutic approach to interpretation that is chiefly concerned with the constitution of life history as meaningful with no consideration given at times to objective truth.     

TREATING WOMEN AS SEX-OBJECTS

In this paper we have two related aims. First, we aim to present an account of what it is to treat women as sex-objects.¹ Like other philosophical writers in the field, we hold that the central idea in an account of such treatment is the failure to treat women with proper respect in sexual behavior. This idea has been cashed out in terms of using,² and in terms of dehumanization or failure to accord equal rights to freedom and welfare.³ However, we believe that there is a central deficiency in most such philosophical accounts of treating women as sex-objects, namely, a failure to outline in any detail a theory of interpersonal norms so that one can grasp in more concrete terms what it is to avoid treating a woman as a sex-object. We aim to rectify this deficiency by presenting a model of interpersonal norms based on the work of the social psychologist Chris Argyris.⁴     

The effect of control and predictability in learned helplessness

The present 2 x 2 study deals with the influence of controllability and predictability of an aversive noise stimulus on a subsequent learning task. Eighty-four subjects participated in two experiments. In correspondence with the concept of learned helplessness, controllability was shown to be the dominant factor in the first experiment. In the second experiment, a modified test task was used in which both factors were shown to act in specific ways: The main influence of controllability is upon response measures (latency, omission), whereas unpredictability retardates learning of new predictive connections. The results are discussed in terms of contingency learning.     

Attributions of responsibility for date and stranger rape

This study examined the effects of the victim-perpetrator relationship on college students' attributions of responsibility for rape. In addition, the rape specificity of these attributions was investigated. College females and males read one of six scenarios that depicted a rape or a proposition, and that varied according to the victim-perpetrator relationship (steady dating partners/acquaintances on a first date/strangers). Then they rated seven responsibility attributions for the rape or proposition. Results indicated that most forms of victim responsibility were stronger for the rape and proposition on a date than for the incidents between strangers, and the findings concerning the perpetrator's responsibility were mixed. The pattern of both victim- and perpetrator-responsibility attributions suggests that both a rape and proposition on a date, compared to incidents between strangers, elicit stronger sex role and sexual attributions. Moreover, male subjects, in comparison to female subjects, gave higher ratings to several responsibility attributions, and these, also, are linked to sex role and sexual considerations. Further, the data revealed that only the perpetrator-responsibility attributions were stronger for the rape than the proposition.This research was supported by the University of Connecticut Research Foundation Grant No. 1171-000-22-00215-35-760.

Choice,Control, and Adaptation Among Elderly Residents of Sheltered Care Settings1

This study examined how elderly residents' adaptation is affected by naturally occurring levels of choice and control in sheltered care facilities. A representative sample of 244 residential care facilities was assessed with the Multiphasic Environmental Assessment Procedure, which measures the quality of residential settings for older people. Overall, facility policies allowing more choice and control were associated with better rated resident well-being, less use of health, daily living assistance, and social-recreational services, and more integration in the community. Policy clarity and the facility social climate factors of independence, influence, and organization mediated the relationship between choice and control and adaptation, and also independently affected residents' adaptation. In addition, in facilities with functionally able residents, more choice and independence were associated with less use of services; in facilities with residents of poor functional ability, choice and independence were unrelated to use of services. Thus, policies that promote more choice and independence may improve adaptation among functionally able residents of sheltered care facilities, without having a detrimental influence on poorly functioning residents.     

Biomagnetism from the neuropsychiatric viewpoint--principles of recent developments in diagnostic procedure

The following survey is intended to demonstrate and discuss some principle problems of biomagnetism and the application in clinical fields. The development of special technical parameters especially by the SQUID method is initiating new possibilities of research and completing the neurobiologically determinated basis and conditions of neuropsychiatric disorders. The Magnetoencephalography (MEG) will be represent an important role of a new functional diagnostic method.
