This research investigates sound length in speech, comparing its physical and mental representation across languages. While English treats length as phonetic variation, languages like Japanese use it meaningfully. The study focuses on Persian to improve speech recognition and therapy, helping determine how sound duration is perceived, produced, and processed cognitively.

This research investigates how sign language experience reshapes the brain’s visual system. MRI studies show expanded hand-processing regions and reorganised face areas in both deaf and hearing signers, even when learning occurs in adulthood. The findings highlight neural plasticity and reveal how visual language transforms perception and brain organisation.

This research investigates how children use the left and right hemispheres for language and spatial reasoning. Using ultrasound while children play custom games, it shows that those with the typical left-language/right-spatial pattern tend to have stronger skills. The findings reveal how brain-activity patterns relate to developmental risks and complex tasks like reading.
