This is typically observed as a greater response to multisensory stimulation relative to the sum of the constituent unisensory responses (i.e., superadditivity). The aim of the present study was to examine whether the temporal principle extends to the cross-modal synchrony of amplitude-modulation (AM) rate. It is well established that psychophysical sensitivity to AM stimulation is strongly influenced by AM rate where the optimum rate differs according to sensory modality. This rate-dependent sensitivity is also apparent from EEG steady-state response (SSR) activity, which becomes entrained to the stimulation rate and is thought to reflect neural processing of the temporal characteristics of AM stimulation. In this study we investigated whether cross-modal congruence of AM rate reveals both psychophysical and EEG evidence of enhanced multisensory integration. To achieve this, EEG SSR and psychophysical sensitivity to simultaneous acoustic and/or vibrotactile AM stimuli were measured at cross-modally congruent and incongruent AM rates. While the results provided no evidence of superadditive multisensory SSR activity or psychophysical sensitivity, the complex pattern of results did reveal a consistent correspondence between SSR activity and psychophysical sensitivity to AM stimulation. This indicates that entrained EEG activity may provide a direct measure of cortical activity underlying multisensory integration. Consistent with the temporal principle of multisensory integration, increased vibrotactile SSR responses and psychophysical sensitivity were found for cross-modally congruent relative to incongruent AM rate. However, no corresponding increase in auditory SSR or psychophysical sensitivity was observed for cross-modally congruent AM rates. This complex pattern of results can be understood in terms of the likely influence of the principle of inverse effectiveness where the temporal principle of multisensory integration was only evident in the context of reduced perceptual sensitivity for the vibrotactile but not the auditory modality.]]> Wed 29 Jan 2020 16:39:10 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:55188 Wed 24 Apr 2024 12:59:56 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:27913 Wed 14 Nov 2018 13:33:37 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:16819 Wed 11 Apr 2018 17:19:46 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:16820 Wed 11 Apr 2018 12:28:20 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:30417 Wed 11 Apr 2018 10:16:02 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:50563 Tue 01 Aug 2023 10:18:31 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:542 Thu 25 Jul 2013 09:10:24 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:42115 Thu 18 Aug 2022 14:21:19 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:38960 Thu 17 Mar 2022 13:04:30 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:16261 Sat 24 Mar 2018 07:54:14 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:24047 Sat 24 Mar 2018 07:09:37 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:32284 Mon 23 Sep 2019 10:58:58 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:2833 Mon 01 Apr 2019 14:03:20 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:53090 Fri 17 Nov 2023 11:58:32 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:51533 Fri 08 Sep 2023 12:11:42 AEST ]]>
