✦ Synopsis


Subjects on a horizontally moving parallel swing perceive a change of the position of the body and of the Subjective Vertical (SV). The magnitude of the SV-change was recorded at different body-positions on the swing. The SVchange was smaller when the vertex-base head-axis was oriented parallel or close to parMlel to swing movement than when the vertex-base head axis was oriented perpendicular to this movement. Perpendicular orientation implies either head vertex-up or head vertex-down. The results are discussed with respect to other findings on the various sensory input systems.

Zusammen/assung. Versuchspersonen anf einer horizontal sehwingenden Parallel-Schaukel nehmen eine Anderung der Lage des eigenen K6rpers und der Stellung der Subjektiven Vertikalen (SV) wahr. Die GrSBe der im Schwingrhythmus wechselnden SV-~_nderung wurde bei verschiedenen K6rperstellungen auf der Schaukel untersucht. Sie war ldeiner, wenn die Scheitel-Basis-Achse des Kopfes in oder nahe der Schwingungsrichtung und gr6i]er, werm sic senkrecht oder nahezu senkrecht dazu stand; die senkrechte Stellung konnte entweder Scheitel-aufwErts oder Scheitel-abw~rts sein. Die Ergebnisse werden im Zusammenhang mit anderen Befunden fiber die beteiligten sensorischen Systeme diskutiert.
