In a recent study, we observed that saccadic distraction (i.e., the remote distractor effect, RDE) was reduced when target and distractor were displayed at unequal contrast [Born, S., & Kerzel, D. (2008). Influence of target and distractor contrast on the remote distractor effect. Vision Research, 48(28), 2805-2816]. We hypothesized that arrival times explain the RDE modulation: With equal cont...

Distraction osteogenesis is a process that depends on biomechanics, where the application of progressive traction forces leads to bone lengthening by gradual new bone formation. (Illizarov, 1989a, 1989b) Consequently, stretching of surrounding soft tissues occurs at different tissue depths, allowing correction of severe skeletal dysplasias in short periods of time. However, biomechanical data f...

The goal of this study was to examine developmental change in visual attention to dynamic visual and audiovisual stimuli in 3-, 6-, and 9-month-old infants. Infant look duration was measured during exposure to dynamic geometric patterns and Sesame Street video clips under three different stimulus modality conditions: unimodal visual, synchronous audiovisual, and asynchronous audiovisual. Infant...

This study deals with uncertainty and attention in audiovisual speech perception. Subjects were exposed to audiovisual stimuli where independent variable was bivalent: either blocked to one ear or uncertainty about in which ear the next stimulus would appear. The hypothesis, that uncertainty would inhibit audiovisual integration was motivated by an earlier study (Öhrström et al, 2011) but these...

Multisensory interactions are well established to convey an array of perceptual and behavioral benefits. One of the key features of multisensory interactions is the temporal structure of the stimuli combined. In an effort to better characterize how temporal factors influence multisensory interactions across the lifespan, we examined audiovisual simultaneity judgment and the degree of rapid reca...

Numerous studies have demonstrated that the structural and functional differences between professional musicians and non-musicians are not only found within a single modality, but also with regard to multisensory integration. In this study we have combined psychophysical with neurophysiological measurements investigating the processing of non-musical, synchronous or various levels of asynchrono...

Some important developments in the area of multimedia applications lead to an open, Internet based environment, for multimedia. These developments include: (a) The popularity of the audiovisual content and its associated services (including the traditional TV and video services); (b) The advent of the digital media; (c) The availability of low-cost audiovisual content management devices; and (d...

This article describes a mathematical method, based on Choice Theory (e.g., Luce, 1963), that can be used to predict audiovisual phoneme confusion matrices from unimodal audio and visual data. The predictions made from this method can be compared to obtained levels of audiovisual processing, for the purpose of identifying individuals whose audiovisual integration processes are not efficient. A ...

Learning audiovisual associations is mediated by the primary cortical areas; however, recent animal studies suggest that such learning can take place even in the absence of the primary visual cortex. Other studies have demonstrated the involvement of extra-geniculate pathways and especially the superior colliculus (SC) in audiovisual association learning. Here, we investigated such learning in ...
