Perceived Congruency in Audiovisual Stimuli Consisting of Gabor Patches and AM and FM Tones

What is it about?

The purpose of this study was to test various combinations of Gabor patches and amplitude (AM) and frequency (FM) modulated tones and determine which parameters of these components are important for the perception of audiovisual congruency/incongruency. We especially focused on whether AM and FM tones with the same modulation frequencies would have a different effect on congruency. Overall, we found that similarity in temporal structure between a Gabor patch and a tone facilitated perceptual congruency, while static parameters like spatial frequency of the Gabor patch or the carrier frequency of the tone had less effect on congruency. Furthermore, the audiovisual combinations with AM-tones received higher congruency ratings then combinations with FM-tones.
