Prozessdissoziationsprozedur: Quo Vadis?
Abstract
Zusammenfassung. Die Prozessdissoziationsprozedur (PDP) ist ein häufig benutztes Instrument zur Erfassung kontrollierter (“bewusster“) und automatischer (“unbewusster“) Gedächtnisprozesse. Die Forschung der letzten zehn Jahre hat jedoch eine Reihe von Problemen im von L. L. Jacoby (1991) vorgeschlagenen Zwei-Prozess-Messmodell aufgezeigt. Dies hat zur Entwicklung von alternativen Modellen geführt, die in dieser Arbeit vorgestellt, systematisiert und bewertet werden. Die Modelle unterscheiden sich auf drei Dimensionen: 1) Modelle mit diskreten vs. kontinuierlichen Prozessvariablen, 2) Modelle mit prüfbaren vs. unprüfbaren Annahmen über die Beziehungen zwischen den Prozessen und 3) Zwei-Prozess-Modelle versus Quellengedächtnismodelle. Für die Zukunft der PDP besonders bedeutsam dürfte sein, dass einige Befunde, die mit Zwei-Prozess-Modellen nur schwer vereinbar sind, plausibel erscheinen, wenn man dieselben Daten im Rahmen von Quellengedächtnismodellen analysiert.
Abstract. The process dissociation procedure (PDP) is an often used instrument for measuring controlled (“conscious”) and automatic (“unconscious”) memory processes. However, research in the past ten years has established several problems in the two-process measurement model proposed by L. L. Jacoby (1991). This has lead researchers to propose alternative measurement models that are briefly summarized, systematized, and evaluated in this article. These models differ on three dimensions: 1) models with discrete vs. continuous process variables, 2) models based on testable vs. untestable assumptions on the relation between processes, 3) two-process models vs. source memory models. Most important for the future of the process dissociation procedure appears to be the fact that some PDP results that are difficult to reconcile with two-process models become plausible when analyzed within the framework of source monitoring models.
