Neural Basis of the Sound-Symbolic Crossmodal Correspondence Between Auditory Pseudowords and Visual Shapes
TLDR
It is suggested that the observed incongruency effects are likely to reflect phonological processing and/or multisensory attention, and advance the understanding of sound-to-meaning mapping in the brain.
Seeing Sounds: The Role of Vowels and Consonants in Crossmodal Correspondences
Crossmodal correspondences refer to the fact that certain domains of features in different sensory modalities are associated with each other. Here, we investigated the crossmodal correspondences
Acoustic and Visual Stimulus Parameters Underlying Sound Symbolic Crossmodal Correspondences
TLDR
It is suggested that sound-symbolic CCs are related to basic properties of auditory and visual stimuli, and thus provide insights into the fundamental nature of sound symbolism and how this might evoke specific impressions of physical meaning in natural language.
Brain networks underlying the processing of sound symbolism related to softness perception
TLDR
Results indicate that the insula and medial superior frontal gyrus play a role in processing sound symbolic information and relating it to the tactile softness information.
The Bouba-Kiki Effect in Children With Childhood Apraxia of Speech.
TLDR
The reduced BK effect in children with CAS supports the notion that cross-modal sensory integration may be altered in these children, which may contribute to speech difficulties in CAS.
Cross-Modal Correspondence Between Speech Sound and Visual Shape Influencing Perceptual Representation of Shape: the Role of Articulation and Pitch.
TLDR
It is found that sound-shape correspondence exerts an effect on shape representation by modulating audiovisual interaction, but only in the case of pitch-varying sounds.
The Role and Priming Effect of Pre-Acquired Memories in Abstract Decision-Making
From a neuropsychological perspective, the brain is confronted daily by decision-making processes. Decision-making is influenced by many factors, from biological stimuli to reward assessments. In
Stimulus Parameters Underlying Sound-Symbolic Mapping of Auditory Pseudowords to Visual Shapes
TLDR
This work establishes the utility of RSA for analysis of large stimulus sets and offers novel insights into the stimulus parameters underlying sound symbolism, showing that sound-to-shape mapping is driven by acoustic properties of pseudowords and suggesting audiovisual cross-modal correspondence as a basis for language users' sensitivity to this type of sound symbolism.
Functional Communication Profiles of Children and Youth with Autism: A Roadmap to Therapeutic and Educational Interventions
TLDR
Examination of in situ education and development attained by children and youth with ASD in a school with a therapeutic and educational curriculum confirmed the utility of FCPs in providing “a roadmap” to needed individual and common curriculum adjustments.

The effect of prior visual information on recognition of speech and sounds.
TLDR
Effective connectivity analyses (dynamic causal modeling) suggest that these incongruency effects may emerge via greater bottom-up effects from early auditory regions to intermediate multisensory integration areas (i.e., STS and AG).
Phonological and orthographic influences in the bouba–kiki effect
TLDR
The results of two studies suggest that the dominant mechanism underlying the bouba–kiki effect for literate subjects is matching based on aligning letter curvature and shape roundedness, which is strong enough to significantly influence word–shape associations even in auditory tasks, where written word forms are never presented to participants.
Audiovisual crossmodal correspondences and sound symbolism: a study using the implicit association test
TLDR
These results rule out selective attention and multisensory integration as possible mechanisms underlying the reported compatibility effects on speeded performance, and highlight the existence of two new crossmodal correspondences using a modified version of the implicit association test (IAT).
Cross-Modality Correspondence between Pitch and Spatial Location Modulates Attentional Orienting
TLDR
The flexible contextual mapping between pitch and location, as well as its susceptibility to top–down control, suggests the pitch-induced cuing effect is primarily mediated by cognitive processes after initial sensory encoding and occurs at a relatively late stage of voluntary attention orienting.

Multisensory Integration in Speech Processing: Neural Mechanisms of Cross-Modal Aftereffects
Traditionally, perceptual neuroscience has focused on unimodal information processing. This is true also for investigations of speech processing, where the auditory modality was the natural focus of
A Comparison of Primate Prefrontal and Inferior Temporal Cortices during Visual Categorization
TLDR
The ITC seems more involved in the analysis of currently viewed shapes, whereas the PFC showed stronger category signals, memory effects, and a greater tendency to encode information in terms of its behavioral meaning.
Natural cross-modal mappings between visual and auditory features.
TLDR
In a series of speeded classification tasks, spontaneous mappings between the auditory feature of pitch and the visual features of vertical location, size, and spatial frequency are found but not contrast.
The effect of temporal asynchrony on the multisensory integration of letters and speech sounds.
TLDR
The results reveal significant interactions between temporal proximity and content congruency in anterior and posterior auditory association cortex, indicating that temporal synchrony is critical for the integration of letters and speech sounds.
