Features of Speech in Inhibited and Uninhibited Children By Maureen Rezendes, Nancy Snidman, Jerome Kagan, and Jane Gibbons 177 The rise of interest in temperamental qualities has raised the consciousness of investigators regarding the best way to conceptualize and to measure this dass of psychological characteristics. We have seen these children--the shy and the sociable, the cautious and the daring--and wondered what makes one avoid new experience and another avidly pursue it. 5 Both kinds of behaviours appear to be partly heritable. What was the result of research done by researchers such as Jerome Kagan regarding genetic factors in a child's basic ... Kagan's proposed two types of temperament: inhibited and uninhibited.

His research on the cognitive and emotional development of a child during the first decade of life focuses on the origins of temperament. However, the fact that the two groups of children also differ in body build, eye color, and susceptibility to atopic allergies (Kagan, 1984) implies two distinct profiles. These two extreme categories of response to novelty have been conceptualized as inhibited and uninhibited temperament, respectively (Kagan, et al., 1987). The developmental psychologist Jerome Kagan studied temperament in infants and defined two temperaments: inhibited and uninhibited.Kagan described these temperament profiles as shy, timid, and fearful for the inhibited child and bold, sociable, and outgoing for the uninhibited child. These proportions of inhibited and uninhibited vary in different class, ethnic, and national groups. Kagan, Jerome; And Others. Children who had been extremely inhibited or uninhibited at 14 and 20 months differed significantly at 4 years of age in behavior and cardiac acceleration.
