“…Thus, the temporal difference between the two signals decreases in convergent brain areas when visual stimuli precede auditory signals by 100 ms. Furthermore, previous studies have found that the timing of auditory and visual stimuli affects integration [44]. These studies have also confirmed that integration is greater when the auditory stimuli are presented in close temporal proximity to the visual stimuli [45,46].…”

Elevated audiovisual temporal interaction in patients with migraine without aura

BackgroundPhotophobia and phonophobia are the most prominent symptoms in patients with migraine without aura. Hypersensitivity to visual stimuli can lead to greater hypersensitivity to auditory stimuli, which suggests that the interaction between visual and auditory stimuli may play an important role in the pathogenesis of migraine. However, audiovisual temporal interactions in migraine have not been well studied. Therefore, our aim was to examine auditory and visual interactions in migraine.MethodsIn this study, visual, auditory, and audiovisual stimuli with different temporal intervals between the visual and auditory stimuli were randomly presented to the left or right hemispace. During this time, the participants were asked to respond promptly to target stimuli. We used cumulative distribution functions to analyze the response times as a measure of audiovisual integration.ResultsOur results showed that audiovisual integration was significantly elevated in the migraineurs compared with the normal controls (p < 0.05); however, audiovisual suppression was weaker in the migraineurs compared with the normal controls (p < 0.05).ConclusionsOur findings further objectively support the notion that migraineurs without aura are hypersensitive to external visual and auditory stimuli. Our study offers a new quantitative and objective method to evaluate hypersensitivity to audio-visual stimuli in patients with migraine.

“…Their stimuli, however, were presented peripherally (40 deg off center). Miller (1982); Berryhill, Kveraga, Webb, and Hughes (2007), and others, with RTs and central presentations, have found evidence against race (separate channels) models and in favor of coactive models. It is possible that information is integrated differently on and off the center of the perceptual field.…”

This investigation brings together a response-time system identification methodology (e.g., Townsend & Wenger Psychonomic Bulletin & Review 11, 391-418, 2004a) and an accuracy methodology, intended to assess models of integration across stimulus dimensions (features, modalities, etc.) that were proposed by Shaw and colleagues (e.g., Mulligan & Shaw Perception & Psychophysics 28, 471-478, 1980). The goal was to theoretically examine these separate strategies and to apply them conjointly to the same set of participants. The empirical phases were carried out within an extension of an established experimental design called the double factorial paradigm (e.g., Townsend & Nozawa Journal of Mathematical Psychology 39, 321-359, 1995). That paradigm, based on response times, permits assessments of architecture (parallel vs. serial processing), stopping rule (exhaustive vs. minimum time), and workload capacity, all within the same blocks of trials. The paradigm introduced by Shaw and colleagues uses a statistic formally analogous to that of the double factorial paradigm, but based on accuracy rather than response times. We demonstrate that the accuracy measure cannot discriminate between parallel and serial processing. Nonetheless, the class of models supported by the accuracy data possesses a suitable interpretation within the same set of models supported by the response-time data. The supported model, consistent across individuals, is parallel and has limited capacity, with the participants employing the appropriate stopping rule for the experimental setting.Keywords Response time .

This question is central to basic human information processing and also possesses many potential applications, from clinical science to human factors and engineering. In the present study, we bring together two previously distinct approaches that can combine to provide strong converging evidence about some of the critical properties of human information processing. The approaches are applicable to the two primary measures of performance in psychological research, response accuracy and response times (hereafter, RTs), so when considered together they allow for strong inference regarding the mechanisms underlying cognitive performance. With regard to the measure of RT, we employed Townsend and Nozawa's (1995) systems factorial technology (hereafter, SFT) framework, and expanded it empirically as we will outline shortly. With regard to the measure of response accuracy, we built on the seminal efforts of Marilyn Shaw and colleagues (e

“…Thus, under this condition, the auditory signal is both temporally and spatially incongruent with the visual signal. Moreover, previous studies have found that the timing of auditory and visual stimuli has effects on integration [9], [47] and also confirmed that integration was greater when the auditory stimuli were presented in close temporal and spatial proximity with the visual stimuli [41], [42]. Thus, it had been suggested that temporal and spatial processing of the two signals were pivotal in determining whether integration would occur.…”

This article aims to investigate whether auditory stimuli in the horizontal plane, particularly originating from behind the participant, affect audiovisual integration by using behavioral and event-related potential (ERP) measurements. In this study, visual stimuli were presented directly in front of the participants, auditory stimuli were presented at one location in an equidistant horizontal plane at the front (0°, the fixation point), right (90°), back (180°), or left (270°) of the participants, and audiovisual stimuli that include both visual stimuli and auditory stimuli originating from one of the four locations were simultaneously presented. These stimuli were presented randomly with equal probability; during this time, participants were asked to attend to the visual stimulus and respond promptly only to visual target stimuli (a unimodal visual target stimulus and the visual target of the audiovisual stimulus). A significant facilitation of reaction times and hit rates was obtained following audiovisual stimulation, irrespective of whether the auditory stimuli were presented in the front or back of the participant. However, no significant interactions were found between visual stimuli and auditory stimuli from the right or left. Two main ERP components related to audiovisual integration were found: first, auditory stimuli from the front location produced an ERP reaction over the right temporal area and right occipital area at approximately 160–200 milliseconds; second, auditory stimuli from the back produced a reaction over the parietal and occipital areas at approximately 360–400 milliseconds. Our results confirmed that audiovisual integration was also elicited, even though auditory stimuli were presented behind the participant, but no integration occurred when auditory stimuli were presented in the right or left spaces, suggesting that the human brain might be particularly sensitive to information received from behind than both sides.
