This study looks at how learning American Sign Language later in life affects how deaf children from hearing families understand and use the language, helping us learn more about their communication skills and thinking abilities.

What this research studies
This research investigates how acquiring American Sign Language (ASL) later in life affects the way individuals process the sounds and structures of the language. It focuses on deaf children who grow up in hearing families and may not learn ASL until after the critical period for language development. By examining the phonological processing abilities of these individuals, the study aims to uncover the long-term effects of late language acquisition on communication skills and cognitive functions. Participants will engage in assessments that analyze their ability to perceive and produce various parameters of ASL, such as handshapes and movements.
Who could benefit from this research
Good fit: Ideal candidates for this research include deaf individuals who acquired ASL after early childhood and are currently between the ages of 0 to 21 or adults over 21.
Not a fit: Patients who are native signers of ASL or those who acquired it from birth are unlikely to benefit from this research.
Why it matters
Potential benefit: If successful, this research could lead to improved educational strategies and support for late learners of ASL, enhancing their communication skills and overall quality of life.
How similar studies have performed: Previous research has shown significant effects of late language acquisition on communication outcomes, indicating that this area of study is both relevant and important.
