“…Most studies investigating the perception and processing of sensory events use simple stimuli, defined as a stimulus that includes a low level of information (Naumer and Kaiser, 2010). More recently, a new approach for the investigation of sensory processing has been developed, using complex stimuli (Naumer and Kaiser, 2010). Complex stimuli, which usually require the processing of several dimensions (Faubert, 2002), have the advantage that they are more similar to everyday life sensory events and convey a higher amount of information than simple stimuli (De Gelder and Bertelson, 2003;Vatakis and Spence, 2006;Naumer and Kaiser, 2010).…”

“…Studies using complex stimuli mostly manipulate one stimulus dimension to investigate the effect of changing one dimension on the perception of another dimension (Garner, 1976;Melara and Marks, 1990b;Neuhoff et al, 2002;Naumer and Kaiser, 2010;Walker and Walker, 2012;Walker et al, 2015). For example, Walker et al (2015) showed that the brightness of visual stimuli interacts with the perception of the size of the stimuli.…”

IntroductionOne-dimensional rating scales are widely used in research and in the clinic to assess individuals’ perceptions of sensory stimuli. Although these scales provide essential knowledge of stimulus perception, their limitation to one dimension hinders our understanding of complex stimuli.MethodsTo allow improved investigation of complex stimuli, a two-dimensional scale based on the one-dimensional Gracely Box Scale was developed and tested in healthy participants on a visual and an auditory task (rating changes in brightness and size of circles and rating changes in frequency and sound pressure of sounds, which was compared to ratings on one-dimensional scales). Before performing these tasks, participants were familiarized with the intensity descriptors of the two-dimensional scale by completing two tasks. First, participants sorted the descriptors based on their judgment of the intensity of the descriptors. Second, participants evaluated the intensity of the descriptors by pressing a button for the duration they considered matching the intensity of the descriptors or squeezing a hand grip dynamometer as strong as they considered matching the intensity of the descriptors.ResultsResults from these tasks confirmed the order of the descriptors as displayed on the original rating scale. Results from the visual and auditory tasks showed that participants were able to rate changes in the physical attributes of visual or auditory stimuli on the two-dimensional scale as accurately as on one-dimensional scales.DiscussionThese results support the use of a two-dimensional scale to simultaneously report multiple dimensions of complex stimuli.

“…The ROIs were tested for multisensory integration using the MAXcriterion, which has been established as a measure of multisensory integration in fMRI and is met when the multisensory response is larger than the maximum of the unimodal responses (Beauchamp, 2005;Naumer et al, 2010b). The MAX-criterion was computed separately for both object categories and groups.…”

Multisensory integration (MI) is defined as the neural process by which unisensory signals are combined to form a new product that is significantly different from the responses evoked by the modality-specific component stimuli. In recent years, MI research has seen exponential growth in the number of empirical and theoretical studies. This study presents a selective overview of formal modeling approaches to MI. Emphasis is on models and measures for behavioral paradigms, such as localization, judgment of temporal order or simultaneity, and reaction times, but some concepts for the modeling of single-cell spike rates are treated as well. We identify a number of essential concepts underlying most model classes, such as Bayesian causal inference, probability summation, coactivation, and time window of integration. Quantitative indexes for measuring and comparing the strength of MI across different paradigms are also discussed. Whereas progress over the last years is remarkable, we point out some strengths and weaknesses of the modeling approaches and discuss some obstacles toward a unified theory of MI.
