Does sound symbolism need sound?: The role of articulatory movement in detecting iconicity between sound and meaninga).

Ever since de Saussure [Course in General Lingustics (Columbia University Press, 1916)], theorists of language have assumed that the relation between form and meaning of words is arbitrary. However, recently, a body of empirical research has established that language is embodied and contains iconicity. Sound symbolism, an intrinsic link language users perceive between word sound and properties of referents, is a representative example of iconicity in language and has offered profound insights into theories of language pertaining to language processing, language acquisition, and evolution.

Objectives: To investigate the influence of frequency-specific audibility on audiovisual benefit in children, this study examined the impact of high- and low-pass acoustic filtering on auditory-only and audiovisual word and sentence recognition in children with typical hearing. Previous studies show that visual speech provides greater access to consonant place of articulation than other consonant features and that low-pass filtering has a strong impact on perception on acoustic consonant place of articulation. This suggests visual speech may be particularly useful when acoustic speech is low-pass filtered because it provides complementary information about consonant place of articulation.

Alzheimers Dement

Cognitive Neuroscience Centre, University of San Andres, Victoria, Buenos Aires, Argentina
Background: Dementia impacts the way individuals perceive and describe everyday events. Alzheimer's disease (AD) notably affects processing of entities manifested by nouns, while behavioral variant frontotemporal dementia (bvFTD) often presents a detached, third‐person perspective. Yet, the potential of natural language processing tools (NLP) to detect these variations in spontaneous speech remains explored.

Alzheimers Dement
December 2024
University of California, Irvine, Irvine, CA, USA
Background: Spontaneous speech is easily obtainable and has the potential to become an accessible and low‐cost marker for cognitive function. The time‐consuming and labor‐intensive nature of speech analysis has been a major obstacle to utilizing this promising tool. This study uses a novel transformer‐based methodology to explore associations between spontaneous speech language features and global cognition.

Alzheimers Dement
December 2024
Mayo Clinic, Rochester, MN, USA
Background: The language symptomology associated with semantic variant primary progressive aphasia (svPPA), namely word finding difficulties with loss of word meaning, leads to multimodal communication difficulties. Given that communication plays an intricate role in establishing and sustaining relationships, svPPA can impact relationships, including those with spouses, in a manner that can only be understood by firsthand experiences. This study aimed to describe a spouse’s experiences of communicating with an individual with svPPA along with the role of communication supports and expectations for speech‐language therapy.
