Manumerische Kognition: Erfassung der Mitwirkung ordinaler, kardinaler und räumlicher Elemente des Fingerzählens bei der Zahlenverarbeitung von Erwachsenen
Zusammenfassung der Projektergebnisse
A series of experiments with adults has documented effects of finger stimulation and finger posturing on numerical cognition. Specifically, we repeatedly observed congruency effects between tactile and visual sensory stimulation patterns and the numerical processing required by our tasks: for example, when one’s index finger is stimulated then the concept “two” is more easily accessible, as measured by faster naming. The same is true when stretching one’s thumb and index finger while bending the remaining finger of the hand. These results are in agreement with an embodied cognition perspective, according to which the sensory and motor activations which are present during acquisition of conceptual knowledge, remain an essential part of this knowledge throughout life. When such activations are induced through sensory stimulation or motor behavior then they enhance knowledge retrieval. This outcome, in turn, suggests that rich sensory and motor experiences are desirable from an educational point of view, consistent with current arguments in the public discourse against premature introduction of digital teaching and learning aids. The availability of advanced motion tracking devices made a strong impact on this project by offering a low-cost yet high-performance tool to record and classify finger poses.
