Abstract Crossmodal correspondences are defined as associations between crossmodal stimuli based on seemingly irrelevant stimulus features (i.e., bright shapes being associated with high-pitched sounds). There is a large body of research describing auditory crossmodal correspondences involving pitch and volume, but not so much involving auditory timbre, the character or quality of a sound. Adeli and colleagues (2014, Front. Hum. Neurosci. 8, 352) found evidence of correspondences between timbre and visual shape. The present study aimed to replicate Adeli et al.’s findings, as well as identify novel timbre–shape correspondences. Participants were tested using two computerized tasks: an association task, which involved matching shapes to presented sounds based on best perceived fit, and a semantic task, which involved rating shapes and sounds on a number of scales. The analysis of association matches reveals nonrandom selection, with certain stimulus pairs being selected at a much higher frequency. The harsh/jagged and smooth/soft correspondences observed by Adeli et al. were found to be associated with a high level of consistency. Additionally, high matching frequency of sounds with unstudied timbre characteristics suggests the existence of novel correspondences. Finally, the ability of the semantic task to supplement existing crossmodal correspondence assessments was demonstrated. Convergent analysis of the semantic and association data demonstrates that the two datasets are significantly correlated (−0.36) meaning stimulus pairs associated with a high level of consensus were more likely to hold similar perceived meaning. The results of this study are discussed in both theoretical and applied contexts.

Teaching poetry offers the teacher of literature some basic and active ways to engage students in learning English because of poetry’s rich language which represents an opportunity for learners to explore meanings and be able to formulate creative responses. One must be aware of the fact that poetry includes various types which differ in forms, and each one of these may have a particular influence on students? learning literature; that is why one centralized the research area on concrete poetry or what is called visual poetry too. This study aims to teach students not only to read and listen to a poem but to develop the skill of creativity through rewriting and this ability would be provoked by the visual shape of the concrete poem. One is trying to bring fun in the EFL classroom and particularly during the literature lecture where students are probably bored by analyzing every line and stanza. So, all these aims were to be concrete via a test, observation and questionnaire. These scientific tools confirmed one’s hypotheses about how positive is concrete poetry for the group of the third-year English L.M.D. students at the University of Djilali Liabes, Sidi Bel Abbes

The bouba/kiki effect—the association of the nonce word bouba with a round shape and kiki with a spiky shape—is a type of correspondence between speech sounds and visual properties with potentially deep implications for the evolution of spoken language. However, there is debate over the robustness of the effect across cultures and the influence of orthography. We report an online experiment that tested the bouba/kiki effect across speakers of 25 languages representing nine language families and 10 writing systems. Overall, we found strong evidence for the effect across languages, with bouba eliciting more congruent responses than kiki . Participants who spoke languages with Roman scripts were only marginally more likely to show the effect, and analysis of the orthographic shape of the words in different scripts showed that the effect was no stronger for scripts that use rounder forms for bouba and spikier forms for kiki . These results confirm that the bouba/kiki phenomenon is rooted in crossmodal correspondence between aspects of the voice and visual shape, largely independent of orthography. They provide the strongest demonstration to date that the bouba/kiki effect is robust across cultures and writing systems. This article is part of the theme issue ‘Voice modulation: from origin and mechanism to social impact (Part II)’.

Human 3D vision is thought to triangulate the size, distance, direction, and 3D shape of objects using vision from the two eyes. But all four of these capacities rely on the visual system knowing where the eyes are pointing. Dr Linton's experimental work on size and distance challenge this account, suggesting a purely retinal account of visual size and distance, and likely direction and 3D shape. This requires new accounts of visual scale and visual shape. For visual scale, he argues that observers rely on natural scene statistics to associate accentuated stereo depth (largely from horizontal disparities) with closer distances. This implies that depth / shape is resolved before size and distance. For visual shape, he argues that depth / shape from the two eyes is a solution to a different problem (rivalry eradication between two retinal images treated as if they are from the same viewpoint), rather than the visual system attempting to infer scene geometry (by treating the two retinal images as two different views of the same scene from different viewpoints). Dr Linton also draws upon his book, which questions whether other depth cues (perspective, shading, motion) really have any influence on this process.

We constantly exploit the statistical regularities in our environment to help guide our perception. The hippocampus has been suggested to play a pivotal role in both learning environmental statistics, as well as exploiting them to generate perceptual predictions. However, it is unclear how the hippocampus balances encoding new predictive associations with the retrieval of existing ones. Here, we present the results of two high resolution human fMRI studies (N=24 for both experiments) directly investigating this. Participants were exposed to auditory cues that predicted the identity of an upcoming visual shape (with 75% validity). Using multivoxel decoding analysis, we found that the hippocampus initially preferentially represented unexpected shapes (i.e., those that violated the cue regularities), but later switched to representing the cue-predicted shape regardless of which was actually presented. These findings demonstrate that the hippocampus in involved both acquiring and exploiting predictive associations, and switches between these modes depending on whether learning is ongoing or complete.

The aim of research is to identify the connection between daylight and museums. A museum may be a place where individuals will explore and learn the past, present and future of history, culture and science. Nowadays museum architecture emphasizes the museum for public interaction and best for education approach. The museum lighting is a challenge with daylight openings. This paper analyses the lighting environment of museum and art galleries with a satisfactory solution of daylight by using different passive design strategies without avoiding the harm to the artifacts and these parameters are good lighting solutions for existing as well as proposed building in terms of sustainability, energy consumption and perseveration. By using these parameters, we can also manage the artificial light and provide an advance solution in LED technologies and lighting solutions can be effectively used to retrofit a museum lighting environment and affecting the connection to the environment. Considering the benefits and challenges of introducing the daylight in museums and galleries. The typology of building and daylight parameters have directly impact on environment and create a visual shape in visitor’s mind. This study is based on majority of heritage buildings current deterioration state prevents those buildings from performing efficiently. A sustainable reuse approach for heritage buildings is considered essential. Old palaces that are usually reused with different functions mostly like museums for their considered interior beauty and unique rich designs. Function alteration along with a deteriorated state augments the energy consumption problem. The optimization of various skylight parameters is evaluated for their combined performance. The results disclose an improved performance which indicates the effectiveness of the energy and day lighting optimized strategies and techniques for heritage reuse. Daylight will help to create building more live, and a step to reducing the climate change and save our environment with global warming.

Purpose This study aims to investigate the effectiveness of a brand imitation strategy for the package design of male-targeted, female-targeted and gender-neutral products. Design/methodology/approach Three (2 × 2 × 2) between-subjects factorial experiments were conducted with three independent variables, namely, visual shape, color and logo, each classified as relevant/divergent. The dependent variables were participants’ attitudes toward the brand, attitudes toward the product and purchase intention. Findings There were no significant main effects or interactions for the male-targeted product. The results for the female-targeted product revealed no significant main effect of visual shape, a significant main effect of color and significant two-way interactions between visual shape and color and between visual shape and logo. Significant main effects were found for visual shape and color for the gender-neutral product. Practical implications A color scheme similar to that of a leading brand in the same product category more powerfully influenced participants’ attitudes and purchase intention, while a more holistically similar design had greater impact than a less holistic design. Some “divergence” or distinctive design elements of the female-targeted product positively influenced participants’ attitudes and behavior. These findings suggest that a brand imitation strategy offers a means for competing in the marketplace, but should be used with caution. Originality/value A conceptual continuum of brand imitation is proposed, incorporating visual semiotics, creativity theory and gender differences in cognitive styles to provide a more systematic method for delineating brand imitation levels.

Shape is a defining feature of objects, and human observers can effortlessly compare shapes to determine how similar they are. Yet, to date, no image-computable model can predict how visually similar or different shapes appear. Such a model would be an invaluable tool for neuroscientists and could provide insights into computations underlying human shape perception. To address this need, we developed a model (‘ShapeComp’), based on over 100 shape features (e.g., area, compactness, Fourier descriptors). When trained to capture the variance in a database of >25,000 animal silhouettes, ShapeComp accurately predicts human shape similarity judgments between pairs of shapes without fitting any parameters to human data. To test the model, we created carefully selected arrays of complex novel shapes using a Generative Adversarial Network trained on the animal silhouettes, which we presented to observers in a wide range of tasks. Our findings show that incorporating multiple ShapeComp dimensions facilitates the prediction of human shape similarity across a small number of shapes, and also captures much of the variance in the multiple arrangements of many shapes. ShapeComp outperforms both conventional pixel-based metrics and state-of-the-art convolutional neural networks, and can also be used to generate perceptually uniform stimulus sets, making it a powerful tool for investigating shape and object representations in the human brain.
