Which of the following is NOT associated with Williams syndrome?

Williams syndrome is a genetic condition characterized by a variety of distinctive features including specific cognitive and behavioral traits. Individuals with Williams syndrome often exhibit hyperacusis, which is an increased sensitivity to certain frequencies and volumes of sound. This heightened auditory sensitivity aligns with the often reported sensory processing differences in individuals with the syndrome.

Delays in motor development are also associated with Williams syndrome. Children with this condition may experience challenges in physical coordination and motor skills, especially in the early stages of development.

On the other hand, individuals with Williams syndrome typically exhibit notable social and verbal fluency. They are often characterized by their extroverted nature and ability to engage in conversation, with a particular gift for language and social interaction. This makes social engagement a strong trait for many individuals with the syndrome.

Severe hearing loss is not a representative trait of Williams syndrome. While some individuals may experience varying degrees of hearing issues, it is not a defining or common characteristic associated with the syndrome. The presence of both hyperacusis and sometimes other auditory processing anomalies tends to dominate the auditory profile of those with Williams syndrome, rather than severe hearing loss. Thus, this option is the one not associated with the disorder.
