“…The results are consistent with the previous findings (Nahorna et al 2012) Navarra et al 2010;Alsius et al 2014). Experiment B shows that attentional mechanisms may intervene at the level of single audiovisual sources in an audiovisual speech scene, selectively increasing or decreasing the amount of fusion depending on the coherence of the attended source.…”

“…For example, when the target location was not varied on a trial-by-trial basis, attention was shown to enhance multisensory integration for simple (e.g., Talsma & Woldorff, 2005) and complex stimuli (e.g., Alsius et al, 2005Alsius et al, , 2007Fairhall & Macaluso, 2009). Differences in the specific task requirements and stimulus properties aside (e.g., see Navarra, Alsius, Soto-Faraco, & Spence, 2010, for a discussion), the majority of these studies have at least shown that MSI can be influenced by endogenous forms of attention. Much less is known about the effects of exogenous spatial attention on MSI.…”

Multisensory integration (MSI) and spatial attention are both mechanisms through which the processing of sensory information can be facilitated. Studies on the interaction between spatial attention and MSI have mainly focused on the interaction between endogenous spatial attention and MSI. Most of these studies have shown that endogenously attending a multisensory target enhances MSI. It is currently unclear, however, whether and how exogenous spatial attention and MSI interact. In the current study, we investigated the interaction between these two important bottom-up processes in two experiments. In Experiment 1 the target location was task-relevant, and in Experiment 2 the target location was task-irrelevant. Valid or invalid exogenous auditory cues were presented before the onset of unimodal auditory, unimodal visual, and audiovisual targets. We observed reliable cueing effects and multisensory response enhancement in both experiments. To examine whether audiovisual integration was influenced by exogenous spatial attention, the amount of race model violation was compared between exogenously attended and unattended targets. In both Experiment 1 and Experiment 2, a decrease in MSI was observed when audiovisual targets were exogenously attended, compared to when they were not. The interaction between exogenous attention and MSI was less pronounced in Experiment 2. Therefore, our results indicate that exogenous attention diminishes MSI when spatial orienting is relevant. The results are discussed in terms of models of multisensory integration and attention.

“…This result suggests that the crossmodal effect of color on odor perception is not mandatory (or, in Stevenson and Oaten's words, "automatic"). As such, it provides some evidence against color influencing odor perception through a process of bottom-up multisensory integration (perhaps leading to sensory dominance) since research in other areas of psychology has shown that multisensory integration tends to be relatively automatic (i.e., unaffected by the performance of a secondary task; see Navarra et al 2009;Santangelo and Spence 2008 for reviews).…”

In this paper, we review the empirical literature concerning the important question of whether or not food color influences taste and flavor perception in humans. Although a superficial reading of the literature on this topic would appear to give a somewhat mixed answer, we argue that this is, at least in part, due to the fact that many researchers have failed to distinguish between two qualitatively distinct research questions. The first concerns the role that food coloring plays in the perception of the intensity of a particular flavor (e.g., strawberry, banana, etc.) or taste attribute (e.g., sweetness, saltiness, etc.). The second concerns the role that food coloring plays in the perception of flavor identity. The empirical evidence regarding the first question is currently rather ambiguous. While some researchers have reported a significant crossmodal effect of changing the intensity of a food or drink's coloring on people's judgments of taste or flavor intensity, many others have failed to demonstrate any such effect. By contrast, the research findings concerning the second question clearly support the view that people's judgments of flavor identity are often affected by the changing of a food or drink's color (be it appropriate, inappropriate, or absent). We discuss the possible mechanisms underlying these crossmodal effects and suggest some of the key directions for future research in order to move our understanding in this area forward.
