| Research Abstract |
To investigate the early development of attention within the framework of temperament, sleep/wake patterns were recorded with actigraphy from 1 or 2 months of age (N = 20), and temperament was assessed using the IBQ-R and the ECBQ from 4 months of age. Eye movement was also assessed longitudinally. The results showed that at 4 months, increased 24-h sleep duration (%) was negatively correlated with negative affectivity. Nocturnal sleep duration (%) at 1 or 2 months of age was negatively correlated with reaction time in the no-gap condition at 6 months of age. In addition, a latent equation model of the questionnaire data (N = 183) using Amos (version 16) clarified relationships between tickling and temperament.
