Resumo
Introduction: Multisensory audiovisual semantic congruency is the process by which
visual information is perceived as integrated to auditory stimuli, because both coincide in
terms of simultaneity and semantic correspondence. This study was aimed at establishing
whether visual percepts, which semantically correspond to auditory stimuli, are associated
with ocular fixations in modulating bottom-up areas while keeping a body posture alignment
between the up-direction and the idiotropic axes, as well as in another orientation corresponding to a vectorial opposition between the up-direction and the head idiotropic axis. Method:
Two groups (one for each position) were selected from a sample of 88 people. A bistable image
was presented on a screen of a fixed 120 Hz eye-tracker device, providing background auditory
stimuli so as to establish semantic congruencies and their relations to ocular fixations. Results:
It was found that audiovisual semantic congruency is associated with fixations when idiotropic
vectors are aligned with the up direction. Fixations manifested in bottom-up modulating areas
are not associated with multisensory audiovisual semantic congruency when the head idiotropic vector is parallel with the gravity vector. Eye fixations decrease significantly if the head
idiotropic axis is aligned with the gravity vector. Conclusion: It is concluded that body position
can affect visual perceptual processes involved in the occurrence of semantic congruency.
