Sound symbols, such as "woof woof" for a dog's barking, imitate the physical properties of their referents. Turkish is a sound symbolically rich language that allows flexible use of such words in different linguistic forms. The current study examined Turkish-speaking parents' use of sound symbolic words to their 14- and 20-month-olds and the concurrent and longitudinal relations between parents' sound symbolic input and infants' vocabulary knowledge. Thirty-four (n = 34) infants were observed at Time-1 (M = 14.23 months, SD = 1.11) and Time-2 (M = 20.30 months, SD = 1.24) during free play sessions with their parents to examine parental input. Infants' vocabulary knowledge was assessed by a parental report. Both the quantity and quality of parental sound symbolic input changed between 14 and 20 months of age. Furthermore, infants' earlier vocabulary knowledge at 14 months negatively predicted parents' later sound symbolic input at 20 months. Last, parents' sound symbolic input was positively and concurrently associated with 14-month-olds' vocabulary knowledge but was negatively and concurrently associated with 20-month-olds' vocabulary levels. These findings suggest an early interaction between infants' exposure to sound symbolic input and their vocabulary development.

Recent studies have revealed that writing systems exhibit systematic relationships between letter shapes and their corresponding sounds, termed 'grapho-phonemic systematicity'. This systematicity manifests differently across writing systems: Semitic languages maximize systematicity through pixel count, Chinese through perimetric complexity, and Korean through Hausdorff distance. This study investigated whether native speakers of these languages would prefer the type of systematicity found in their respective writing systems.

Efficient learning of letters-speech sound associations results in the specialization of visual and audiovisual brain regions, which is crucial for the development of proficient reading skills. However, the brain dynamics underlying this learning process remain poorly understood, and the involvement of learning and performance monitoring networks remains underexplored. Here we applied two mutually dependent feedback learning tasks in which novel symbol-speech sound associations were learned by 39 healthy adults.

Reading relies on the ability to map written symbols with speech sounds. A specific part of the left ventral occipitotemporal cortex, known as the Visual Word Form Area (VWFA), plays a crucial role in this process. Through the automatization of the mapping ability, this area progressively becomes specialized in written word recognition.

Introduction: The integration of artificial intelligence (AI) into medical text generation is transforming public health by enhancing clinical documentation, patient education, and decision support. However, the widespread deployment of AI in this domain introduces significant ethical challenges, including fairness, privacy protection, and accountability. Traditional AI-driven medical text generation models often inherit biases from training data, resulting in disparities in healthcare communication across different demographic groups.

Temporospatial and semantic multisensory aspects contribute to bodily and spatial perception. An informative paradigm to study this is the Auditory Pinocchio Illusion, in which participants perceive an elongation of their finger upon vertically pulling their finger and hearing a concurrent upward pitch glissando. This arguably relies on anchoring (i.
