Psychologie der Informationsverarbeitung

Adaptives und intelligentes Verhalten zu verstehen, ist eine der zentralen wissenschaftlichen Fragen unserer Zeit. Während Künstliche Intelligenz das Ziel hat, intelligente Computerprogramme und Maschinen herzustellen, ist das Ziel der Kognitionswissenschaft, menschliches und intelligentes Verhalten mit Methoden der Künstlichen Intelligenz und des Maschinellen Lernens zu verstehen und vorherzusagen.

Ein besseres Verständnis menschlichen Verhaltens bei der Lösung komplexer Aufgaben, der im Menschen ablaufenden Informationsverarbeitung, der entsprechenden Algorithmen, und wie diese im Gehirn umgesetzt werden, verspricht die Art und Weise zu revolutionieren, wie wir uns selbst verstehen und wie wir Technologie entwickeln.

Unsere Arbeitsgruppe erforscht, wie Menschen ihre Wahrnehmungssysteme aktiv in komplexen Situationen benutzen um Entscheidungen und Handlungen zu steuern. Dabei untersuchen wir, wie das visuelle System sensorische Informationen benutzt um Vorstellungen über die Umwelt zu generieren, wie die Informationsverarbeitung von internen Repräsentationen beeinflusst wird und wie wir Handlungen darauf aufbauend ausführen. Unsere Arbeit zeigt dabei sowohl experimentell als auch theoretisch, dass Wahrnehmen, Entscheiden, Handeln und Lernen untrennbar miteinander verwoben sind.

Dabei benutzen wir eine Herangehensweise, die unterschiedliche Methoden integriert:

  • experimentelle Studien, in denen wir meist Augen- und Körperbewegungen bei ausgedehntem Verhalten in natürlichen und virtuellen Umgebungen messen,
  • Entwicklung und Anwendung von Methoden der inversen optimalen Steuerung und Regelung sowie des inversen Reinforcement Learnings, die es erlauben, individuelle, subjektive, kognitive Modelle, Kosten sowie Vorstellungen aus menschlichem Verhalten zu schätzen,
  • Modellierung von visuomotorischen Aufgaben und deren Lösung mit Methoden des maschinellen Lernens,
  • Entwicklung von Methoden zur quantitativen Messung sequentiellen menschlichen Verhaltens,
  • Simulationen von sequentiellen Entscheidungen in naturalistischen Umgebungen,
  • Entwicklung von Lernalgorithmen zur Lösungen von Wahrnehmungs- und Handlungsaufgaben.


Unsere Forschungsgruppe ist Teil des Centre for Cognitive Science und des Instituts für Psychologie im Fachbereich Humanwissenschaften der Technischen Universität Darmstadt. Wir sind auch Teil des Hessischen Zentrums für KI, hessian.ai, der Ellis Unit Darmstadt und der Konrad-Zuse-Schule für Exzellenz in Künstlicher Intelligenz, ELIZA.
