Williams syndrome and happiness
Abstract:
Williams syndrome is a genetic disorder resulting in a variety of medical and developmental features, one of which is a frequent outward presentation of substantial happiness. In this paper we describe the unique expression of happiness in people with Williams syndrome, with several anecdotes and a frame by frame conversational analysis. We then discuss this happiness in the context of other dimensions of the impact of Williams syndrome, especially anxiety. We conclude with a discussion of the role of genetics in emotions.
