Making the Invisible Visible: Verbal but Not Visual Cues Enhance Visual Detection
Background: Can hearing a word change what one sees? Although visual sensitivity is known to be enhanced by attending to the location of the target, perceptual enhancements of following cues to the identity of an object have been difficult to find. Here, we show that perceptual sensitivity is enhanced by verbal, but not visual cues. Methodology/Principal Findings: Participants completed an object detection task in which they made an object-presence or-absence decision to briefly-presented letters. Hearing the letter name prior to the detection task increased perceptual sensitivity (d9). A visual cue in the form of a preview of the to-be-detected letter did not. Follow-up experiments found that the auditory cuing effect was specific to validly cued stimuli. The magnitude of the cuing effect positively correlated with an individual measure of vividness of mental imagery; introducing uncertainty into the position of the stimulus did not reduce the magnitude of the cuing effect, but eliminated the correlation with mental imagery. Conclusions/Significance: Hearing a word made otherwise invisible objects visible. Interestingly, seeing a preview of the target stimulus did not similarly enhance detection of the target. These results are compatible with an account in which auditory verbal labels modulate lower-level visual processing. The findings show that a verbal cue in the form of hearing a word can influence even the most elementary visual processing and inform our understanding of how language affect
Dutch modality exclusivity norms : Simulating perceptual modality in space
Perceptual information is important for the meaning of nouns. We present modality exclusivity norms for 485 Dutch nouns rated on visual, auditory, haptic, gustatory, and olfactory associations. We found these nouns are highly multimodal. They were rated most dominant in vision, and least in olfaction. A factor analysis identified two main dimensions: one loaded strongly on olfaction and gustation (reflecting joint involvement in flavor), and a second loaded strongly on vision and touch (reflecting joint involvement in manipulable objects). In a second study, we validated the ratings with similarity judgments. As expected, words from the same dominant modality were rated more similar than words from different dominant modalities; but - more importantly - this effect was enhanced when word pairs had high modality strength ratings. We further demonstrated the utility of our ratings by investigating whether perceptual modalities are differentially experienced in space, in a third study. Nouns were categorized into their dominant modality and used in a lexical decision experiment where the spatial position of words was either in proximal or distal space. We found words dominant in olfaction were processed faster in proximal than distal space compared to the other modalities, suggesting olfactory information is mentally simulated as "close" to the body. Finally, we collected ratings of emotion (valence, dominance, and arousal) to assess its role in perceptual space simulation, but the valence did not explain the data. So, words are processed differently depending on their perceptual associations, and strength of association is captured by modality exclusivity ratings
Appraisal of space words and allocation of emotion words in bodily space
The body-specificity hypothesis (BSH) predicts that right-handers and left-handers allocate positive and negative concepts differently on the horizontal plane, i.e., while left-handers allocate negative concepts on the right-hand side of their bodily space, right-handers allocate such concepts to the left-hand side. Similar research shows that people, in general, tend to allocate positive and negative concepts in upper and lower areas, respectively, in relation to the vertical plane. Further research shows a higher salience of the vertical plane over the horizontal plane in the performance of sensorimotor tasks. The aim of the paper is to examine whether there should be a dominance of the vertical plane over the horizontal plane, not only at a sensorimotor level but also at a conceptual level. In Experiment 1, various participants from diverse linguistic backgrounds were asked to rate the words “up”, “down”, “left”, and “right”. In Experiment 2, right-handed participants from two linguistic backgrounds were asked to allocate emotion words into a square grid divided into four boxes of equal areas. Results suggest that the vertical plane is more salient than the horizontal plane regarding the allocation of emotion words and positively-valenced words were placed in upper locations whereas negatively-valenced words were placed in lower locations. Together, the results lend support to the BSH while also suggesting a higher saliency of the vertical plane over the horizontal plane in the allocation of valenced words.Fernando Marmolejo-Ramos, María Rosa Elosúa, Yuki Yamada, Nicholas Francis Hamm and Kimihiro Noguch

Museum Topology and the Will to Connect
This paper is concerned with the relationship between material culture and spatiality. Through the example of the ceramics collection in the City Museum and Art Gallery in Stoke-on-Trent, England, an analysis is made of the topological character of space that is folded around certain objects on display. Ozzy the Owl, a 17th Century slipware owl jug, who was discovered on BBC TV's Antiques Roadshow in 1990 and subsequently bought by the museum, is seen as an agent that is constituted by the folding together of preface and afterword in the museum display, unsettling its (Euclidean) geometry, (Kantian) aesthetic and discourse of improvement (Organised around Wedgwood). Ozzy brings complexity and connection; his contingent location within the museum's heterogeneous material netwek reveals the functional blankness of objects and the effects that this can have in performing new topological arrangements in a space, revealing the friability and partial connectedness of its narrativity
Embodied rationality
Recent developments in embodied cognition in the field of cognitive science support an expanded notion of rationality. I attempt to explicate this expanded notion by introducing the concepts of embodied rationality and enactive hermeneutics. I argue that bodily performance is rational and that there is continuity between the rational movements of the body and reflective thinking understood as a skill
