Beiträge zur sensori-tonischen Feldtheorie der Wahrnehmung

Zusammenfassung 30 weibliche und 30 männliche Versuchspersonen gaben im Dunkelraum bzw. mit geschlossenen Augen bei seitlicher Körperneigung bis in die Horizontale an, in welcher Position ihnen eine Leuchtlinie und ein Metallstab senkrecht erschienen. In nichtlinearer Abhängigkeit vom Grad der Körperneigung zeigten sich dabei Abweichungen der scheinbaren von der objektiven Vertikalen. Die Tendenz dieser Abweichung war für den visuellen wie für den taktilen Wahrnehmungsbereich gleich, bei geringer Körperneigung entgegen, bei großer Körperneigung in die Richtung der Neigung, wobei letztere Tendenz stärker für die visuelle Vertikale ausgeprägt war. Die Ergebnisse wurden auf dem Boden der sensoritonischen Wahrnehmungstheorie interpretiert, nach der sich die Veränderungen in der Lage der scheinbaren Vertikalen nach dem Prinzip der sensori-tonischen Induktion auf Tonusveränderungen des Organismus durch die Scitwärtsneigung zurückführen lassen. Zur Erklärung der nichtlinearen Beziehung zwischen Körperneigung und Abweichung der scheinbaren Vertikalen wurde ein dynamisches Kräftespiel zwischen einer Tendenz zur Reizzuwendung und einer im Dienst der Konstanterhaltung der Wahrnehmungswelt dieser entgegenwirkenden Reaktion angenommen. Das Ergebnis dieses Kräftespiels ließ sich interpretieren, wenn man die Bedeutung einer Konstanterhaltung der Raumdimensionen in aufrechter gegenüber liegender Körperstellung für den visuellen Fernraum gegenüber dem taktilen Nahraum berücksichtigt.

Summary Thirty male and 30 female Ss indicated by means of a luminescent rod in the darkroom and by means of a metal bar with closed eyes the vertical direction of space under systematic variation of tilt from erect to the horizontal position. Deviations of apparent from true vertical had a non-linear relation to the degree of body tilt. The trend of deviations was similar for the visual and tactual experiment: With small angles of body tilt apparent vertical tended to deviate opposite to the direction of tilt; with large degrees of tilt apparent vertical tended to deviate in the direction of tilt. The latter tendency was more pronounced for visual than for tactual vertical.The results were interpreted in keeping with sensory-tonic field theory of perception, according to which deviations of apparent vertical were due to changes in the sensory-tonic state of the organism. Such changes were experimentally introduced through lateral body tilt. To explain the non-linear relation between deviations of apparent vertical and the degree of body tilt, it was hypothesized that there is a dynamic interplay between a primary tendency of the organism to towards stimulation and a secondary opposing tendency serving the maintenance of constancy of spatial dimensions. The result of this interplay was interpreted by introducing the notion of biological relevance of spatial constancy of the upright position versus the reclining position for visual far-space and tactual near-space.

Über Wahrnehmungsverhalten beim 8- bis 10wöchigen Säugling

Zusammenfassung Im Rahmen einer Systemtheorie des Verhaltens und der Persönlichkeit und auf dem Hintergrund der Ergebnisse der Berner Längsschnittuntersuchungen wird eine Hypothese über die Genese der Wahrnehmung entwickelt, wonach die frühesten Wahrnehmungen im wesentlichen Verarbeitungen der Reizwirkungen in einer von zwei Klassen von Verhaltenssystemen sind, nämlich der Abwendung und Selbstsicherung (A-Systeme) bzw. der Zuwendung zur Außenwelt (Z-Systeme).In einem Experiment mit 8-, 9- und l0wöchigen Säuglingen wurde das Wahrnehmungsverhalten in Abhängigkeit von verschiedenen Reizfiguren, von der individuellen Eigenart und vom Aktivationsniveau des Kindes mit Hilfe eines Zeitstichprobenverfahrens beobachtet. Der auf die Differenzierung zwischen den verschiedenen Reizfiguren entfallende Varianzanteil steigt mit zunehmendem Alter an, während die Wirkung der autonomen Aktivationsprozesse allmählich zurücktritt. Mit 10 Wochen kann eine geordnete Form oder gute Gestalt leichter verarbeitet werden als eine mehr zufällige Form.Einige Probleme im Zusammenhang mit Annahmen, Methoden und Ergebnissen des Experiments werden diskutiert, darunter die Theorie der Formwahrnehmung, die Genese von Subjekt- und Objektsystem und die beschränkte Bedeutung der Methode der bevorzugten Fixierung in der Erforschung der Säuglingswahrnehmung.

Summary Within the framework of a System Theory of behavior and personality and against the background of the results of the Bernese Longitudinal Studies, a hypothesis of the genesis of perception is developed. It states that the earliest perceptions are essentially integrations of the effects of stimuli into one of two classes of behavioral systems, viz. withdrawal and self-preservation (A-systems) or, respectively, approach to the outer world (Z-systems).The perceptual behavior of 8-, 9-, and 10-week-old infants as a function of different stimulus forms, individuality, and activation level was observed by means of a time-sampling rating method. The proportion of variance accounted for by the differences between stimuli was found to increase with age; at the same time the effect of autonomic activation processes was decreasing. At the age of 10 weeks the infant can work up an orderly form or good Gestalt more readily than a more irregularly-shaped form.Some problems in connection with the assumptions, methods, and results of the study are then discussed, including form perception theory, the genesis of subject- and object-system, and some restriction of the method of preferred fixation in the study of infant perception.

The effect of encoding training on perceptual recall

The effect of encoding training on tachistoscopic performance was measured by training groups of Ss in either an octal or a standardized English encoding of nine place binary numbers. A control group of Ss was allowed to encode ad lib during an equivalent training period. Performance was measured before, during and after the encoding training. It was found that imposing a code on S impaired tachistoscopic performance both during and for some time after the encoding training. Possible reasons for this effect are discussed.     

Investigations of a mirror-image transfer effect in pigeons

In two separate experiments, pigeons trained binocularly to peck a key on which an oblique line (e.g., 60 degrees counter-clockwise rotation from horizontal) was projected yielded bi-modal angularity generalization gradients in extinction, with peaks of responding at both the training stimulus and its mirror image (in this case 120 degrees ). This mirror-image transfer effect may be analogous to an "octave effect" in auditory generalization, but Mello's finding of a mirror-image reversal transfer effect following monocular training in pigeons suggests an alternative interpretation.     

An Existential View Of Vocational Development

The paper is an attempt to point out that the literature of existential philosophy has produced a meaningful theory of vocational development. The theory not only appears to be cogent, but also lines up closely with current thinking in the field. The contrast with various authors is an attempt to illucidate through similarity the ultimate ramifications of the existential theory. An equally important aspect of this theory is that within it one discovers an explanation of work alienation. Finally, there is every reason to believe that the existentialists have produced only a small portion of the potential theoretical model.     

Cooperative Guidance and Instructional Programs for Leadership Preparation

This article outlines a sequential series of leadership programs, from elementary school to college level, that will serve to integrate the guidance and instructional processes. Leadership is viewed as one of the four main categories of talent: “academic, creative, kinesthetic (e.g., crafts, athletics), and psychosocial (e.g., leadership).” It is suggested that potential participants for leadership training might be identified by screening and nomination, case study, program planning and placement, and follow-up and evaluation. A four-front program of counseling-instructional activities including individual counseling, group counseling, seminars, and advanced classes is described. It is hypothesized that the interaction of teachers and counselors in actual curriculum building will lead to genuinely individualized educational programming.     

The Pavlovian basis of reciprocal inhibition therapy

While there is a slight disagreement between Wolpe’s views and Pavlov’s statements concerning the application of experimental psychology to the study of psychiatry, Wolpe indicates that he owes much to Pavlov. A Pavlovian analysis of therapy by reciprocal inhibition, which includes the physiological constructs as well as Pavlovian methodology, will increase our understanding of Reciprocal Inhibition therapy. The major techniques of Reciprocal Inhibition therapy are discussed in the terms of Pavlovian method and theory. Desensitization based on systematic relaxation appears to be effective because the excitatory stimulus is presented when the subject’s cortex is predominantly in an inhibitory state while relaxed. Assertive training relies mainly on building up the excitatory process by use of the second signal system. Thought-stopping is analogous to the external inhibition procedure with the use of the second signaling system as the “extra” stimulus. Deductions from Pavlov’s typology predict that an excitable subject will be difficult to desensitize and somewhat easier to train in assertive behavior and thought-stopping. Some implications of relating Pavlovian method and theory to Reciprocal Inhibition therapy are discussed.
