“…This finding deviates from the results of Poliakoff et al (2006), which show that for a population of young adults a visual stimulus had to be presented 40 ms before the tactile stimulus for the signals to be perceived as occurring simultaneously. Poliakoff et al reported that the different perceptual latencies they found for visual and tactile signals are not constant across lifetime but vary with age.…”

“…In simultaneity judgments, for example, it was found that when presenting crossmodal signals such as brief light flashes, beeps, or tactile stimuli in physical simultaneity observers perceive them as occurring sequentially (Poliakoff, Shore, Lowe, & Spence, 2006;Zampini, Brown, Shore, Maravita, Röder and Spence, 2005;Zampini, Guest, Shore and Spence, 2005). Simultaneity of auditory and visual stimuli is commonly perceived when the visual stimulus precedes the auditory stimulus by about 20 to 30 ms (Zampini, Guest, et al, 2005), simultaneity of auditory and tactile stimuli is commonly perceived when the tactile stimulus precedes the auditory stimulus between 1.1 ms and 13.4 ms (Zampini, Brown, et al, 2005), and simultaneity between visual and tactile stimuli is commonly achieved when visual stimuli are presented 40 ms before tactile ones (Poliakoff et al, 2006).…”

Duration perception in crossmodally-defined intervals

How humans perform duration judgments with multisensory stimuli is an ongoing debate. Here, we investigated how sub-second duration judgments are achieved by asking participants to compare the duration of a continuous sound to the duration of an empty interval in which onset and offset were marked by signals of different modalities using all combinations of visual, auditory and tactile stimuli. The pattern of perceived durations across five stimulus durations (ranging from 100 ms to 900 ms) follows the Vierordt Law. Furthermore, intervals with a sound as onset (audio-visual, audio-tactile) are perceived longer than intervals with a sound as offset. No modality ordering effect is found for visualtactile intervals. To infer whether a single modality-independent or multiple modalitydependent time-keeping mechanisms exist we tested whether perceived duration follows a summative or a multiplicative distortion pattern by fitting a model to all modality combinations and durations. The results confirm that perceived duration depends on sensory latency (summative distortion). Instead, we did not find evidence for multiplicative distortions. The results of the model and the behavioural data support the concept of a single time-keeping mechanism that allows for judgments of durations marked by multisensory stimuli.

“…In Experiment 1, we assessed how accurately each group could judge temporal order in task wherein two white squares were presented on opposite sides of a screen and participants were asked to respond which appeared first. Our results revealed that both healthy aging and PD reduce temporal order detectability, which agrees with previous reports (Poliakoff, Shore, Lowe, & Spence, 2006;Fiorio et al, 2008;Ulbrich, Churan, Fink, & Wittmann, 2009;Szymaszek, Sereda, Pöppel, & Szelag, 2009).…”

“…Other works have uncovered a similar reduction in the temporal order acuity of visual stimuli (Ulbrich et al, 2009), of auditory stimuli (Szelag, Szymaszek, & Kolodziejczyk, 2006;Szymaszek et al, 2009;Ulbrich et al, 2009), and of stimuli that involve both the visual and tactile modalities (Poliakoff et al, 2006). Together, these results suggest that aging alters temporal order perception.…”

“…Furthermore, previous studies using concurrent presentations of auditory and visual stimuli in simple detection tasks showed enhanced crossmodal facilitation in older compared to younger adults (Diederich, Colonius, & Schomburg, 2008;Laurienti, Burdette, Maldjian, & Wallace, 2006;Peiffer, Mozolic, Hugenschmidt, & Laurienti, 2007). On the other hand, although older adults benefit more than young adults from temporally-and semantically-congruent cross-modal information, they also show greater impairment in integrating incongruent cross-modal inputs (Poliakoff, Coward, Lowe, & O'Boyle, 2007;Poliakoff, Shore, Lowe, & Spence, 2006;Setti et al, 2011).…”

Visual dominance and multisensory integration changes with age

Objects comprise of visual and auditory signatures that arrive through distinct sensory channels. Exposure to cross-modal events sets up expectations about what a given object most likely "sounds" like, and vice versa, thereby facilitating detection and recognition. Whereas episodic and working memory functions decline with age, the extent to which multisensory integration processes change with age remains an open question. In the present study, we examined whether multisensory integration processes play a compensatory role in normal aging. Magnetoencephalography recordings of semantically-related cross-modal and unimodal auditory and visual stimuli captured the spatiotemporal dynamics of multisensory responses in young and older adults. Whereas sensory-specific regions showed increased activity in response to cross-modal compared to unimodal stimuli 100 ms after stimulus onset in both age groups, posterior parietal and medial prefrontal regions responded preferentially to cross-modal stimuli between 150 and 300 ms in the older group only. Additionally, faster detection of cross-modal stimuli correlated with increased activity in inferior parietal and medial prefrontal regions 100 ms after stimulus onset in older compared to younger adults. Age-related differences in visual dominance were also observed with older adults exhibiting significantly larger multisensory facilitation effects relative to the auditory modality. Using structural equation modeling, we showed that age-related increases in parietal and medial prefrontal source activity predicted faster detection of cross-modal stimuli. Furthermore, the relationship between performance and source activity was mediated by age-related reductions in gray matter volume in those regions. Thus, we propose that multisensory integration processes change with age such that posterior parietal and medial prefrontal activity underlies the integrated response in older adults.
