Aus den Anfängen der GTA und der Gestalttheoretischen Psychotherapie – Ein Rückblick anlässlich der 80. Geburtstage von Hans-Jürgen Walter und Hilarion Petzold

Abstract In diesem Beitrag werden die Anfänge der GTA und der Gestalt Theory ab Ende der 1970er Jahre nachgezeichnet. Diese Anfänge waren angesichts der Zerschlagung der Gestaltpsychologie und der Vertreibung eines großen Teils ihrer akademischen Vertreter durch das Nazi Regime überaus schwierig: War mit dem Ende des sog. „Dritten Reiches“ die Nazi-Ideologie in Deutschland noch keineswegs überwunden, was sich u.a. auch darin zeigte, dass man sich nicht erinnern mochte, welche bedeutende international geachteter Richtung mit der Berliner Schule der Gestaltpsychologie vor dem Nazi-Regime die Psychologie in Deutschland prägte, geschweige denn, dass man sich bemüht hätte, führende Vertreter zurück zu gewinnen. Der Fokus der Darstellung ist aber auch auf die beiden Persönlichkeiten Hans-Jürgen Walter und Hilarion Petzold gerichtet, die aus der Gestalttherapie kommend umfassende Konzepte von Psychotherapeutischem Verständnis entwickelten, die unter der Bezeichnung „Gestalttheoretische Psychotherapie“ und „Integrative Therapie“ wichtige Grundsteine auch für heutige Diskurse darstellen. Beide konnten am 25. März 2024 ihren 80. Geburtstag feiern, wobei die Gratulation seitens der GTA auch das Gedenken an Rainer Kästl einschließt, der ebenfalls für die Entwicklung der Gestalttheoretischen Psychotherapie Bedeutendes beigetragen hat, seinen 75. Geburtstag in 2024 aber aufgrund seines frühen Todes (2020) nicht begehen konnte.

Acoustic Depth

Summary Acoustic depth is an elusive indicator that touches the world of emergencies, or perceptual focus, in a peculiar way. The realm in which these forms of recognition operate indeed links media theory to perception theory and aesthetic reflection. Expressions such as acoustic scene, sound depth or sharpness, or acoustic image when discussing the receptive forms of various microphone models, are just a few cases where imaginative synthesis translates the sense of phenomena arising from the resistance of sensory properties to the structures of linguistic formalization. The language of media is full of these references, which seem to refer to a common sense that emerges in the differentiation of perceptual channels, but is rarely made explicit in a clear manner. To understand acoustic depht’s nature, we can use the concept of emergence: every time we hear a sound, that acoustic process is always surrounded by a myriad of small sounds that interact with it. The notion of emergence can be applied to anything present in the surrounding environment. It can be applied to any configuration that breaks the homogeneity of a perceptual field. So, we can analyze the complexity of this synthetic formation by tracing it back to increasingly simpler synthetic planes. When talking about composition, synthesis, and association, it has already the results of compositional operations and which provided the ultimate or primary material – either term suffices, depending on the direction we choose to take. These are essential factors in spatial orientation processes, but they are structurally opaque: we’ll work on three examples taken from classical music, ethnomusicology, and hearing aids.

Enhanced distractor filtering in habituation contexts: Learning to ignore is easier in familiar environments

Summary Habituation mechanisms play a pivotal role in enabling organisms to filter out irrelevant stimuli and concentrate on essential ones. Through repeated exposure, the brain learns to disregard stimuli that are irrelevant, effectively ceasing to respond to potentially distracting input. Previous studies have demonstrated that the orienting response to visual distractors disrupting visual detection tasks habituates as tasks progress and distractors are encountered repeatedly, as their initial interference diminishes. Theoretical models posit that this reduction is contingent upon the establishment of an internal representation of external stimuli. Moreover, further studies have indicated that habituation can be context- specific, suggesting that the mechanisms involved incorporate information about features of irrelevant stimuli that extend beyond their discrete characteristics. In this contribution, we further delved into the question of whether the context in which habituation occurs retains a general habituative capacity when a new, to-be-ignored stimulus is introduced. We discuss evidence indicating that the context in which habituation has already taken place facilitates the habituation process for a new stimulus. This suggests that it becomes easier to ignore new stimuli in contexts where we have already learned to disregard other stimuli, underscoring the intricate interplay between habituation, context, and attentional processes.
