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 ]]> The Ototoxic potential of cobalt From metal-on-metal hip implants: objective auditory and vestibular outcome https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:39578 Wed 27 Jul 2022 09:23:32 AEST ]]> Evaluating monitoring methods to guide adaptive management of a threatened amphibian (Litoria aurea) https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:19056 Wed 11 Apr 2018 15:45:47 AEST ]]> Making Sense of Mismatch Negativity https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:40864 Tue 19 Jul 2022 14:10:35 AEST ]]> Detecting an intention to communicate from nonword sounds https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:43160 Tue 13 Sep 2022 15:35:25 AEST ]]> Why mismatch negativity continues to hold potential in probing altered brain function in schizophrenia https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:54261 Tue 13 Feb 2024 13:32:14 AEDT ]]> Extending the temporal principle of multisensory integration: a psychophysical and EEG investigation of cross-modal acoustic and vibrotactile amplitude modulation https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:35791 Thu 28 Nov 2019 16:30:07 AEDT ]]> Surprising sequential effects on MMN https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:24086 Thu 24 Mar 2022 08:57:28 AEDT ]]> Backward recognition masking and auditory N1 ERP enhancements at brief stimulus intervals https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:2956 Sat 24 Mar 2018 08:31:00 AEDT ]]> Dynamic representational plasticity in sensory cortex https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:1388 Sat 24 Mar 2018 08:28:01 AEDT ]]> Neuropsychological correlates of auditory perceptual inference: a mismatch negativity (MMN) study https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:10856 Sat 24 Mar 2018 08:12:42 AEDT ]]> The use of conditional inference to reduce prediction error-A mismatch negativity (MMN) study https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:11468 Sat 24 Mar 2018 08:11:09 AEDT ]]> Changes in mid-to-late latency auditory evoked responses in the chicken during neural maturation https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:10941 Sat 24 Mar 2018 08:10:40 AEDT ]]> Sensory suppression effects to self-initiated sounds reflect the attenuation of the unspecific N1 component of the auditory ERP https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:19906 Sat 24 Mar 2018 08:03:47 AEDT ]]> Gray matter deficits, mismatch negativity, and outcomes in schizophrenia https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:17666 Sat 24 Mar 2018 07:57:48 AEDT ]]> Biased relevance filtering in the auditory system: a test of confidence-weighted first-impressions https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:29357 Sat 24 Mar 2018 07:34:16 AEDT ]]> Unilateral auditory neuropathy spectrum disorder: retrocochlear lesion in disguise? https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:26939 Sat 24 Mar 2018 07:27:30 AEDT ]]> Effects of incremented auditory feedback on remote vehicle operator task performance https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:54115 Mon 05 Feb 2024 10:03:47 AEDT ]]>
