Shyness, sensation seeking and birth-order position

The study found no relationship between birth-order position and shyness or sensation seeking in a sample of 250 students. Shyness was significantly negatively correlated with total sensation seeking scores and scores on the four subscales, but closer analysis showed that this relationship was mediated by the correlation between shyness and disinhibition. This pattern implies that shyness is wariness specifically in social situations.
