Decades of research on the study of introversion and extraversion have allowed researchers to distinguish among individual differences on each of these dimensions. Research indicates that shyness, a rather common personality trait, is a construct that is related, but not identical, to introversion. Once regarded as a unitary construct, modern day personality theorists propose that shyness is ba...

Young children’s relationships with teachers predict social and academic success. This study examines contributions of child temperament (shyness, effortful control) and gender to teacher–child relationship quality both directly and indirectly through the frequency of teacher–child interactions in the classroom. Using an NICHD SECCYD sample of 819 first grade children, four findings emerged: (a...

Perceptions of intelligence were investigated in 2 longitudinal studies of leaderless discussion groups (LDGs). In Study 1 (N = 87), students completed trait-shyness questionnaires and met 7 times in groups of 4-5. After Meetings 2 and 7, participants rated all group members on state shyness and intelligence. Trait-shy participants were initially judged to be less intelligent on both self- and ...

Structured diagnostic interviews were obtained from biological parents of 770 participants. Potential risk factors assessed included child characteristics: negative affect, shyness, separation anxiety...

The nature of the relationship between shyness and social phobia can be clarified by assessing rates of social phobia in highly shy and normative samples. In the present study, 2202 participants were screened and categorized on a shyness scale as highly shy (90th percentile) or "normatively" shy (40-60th percentile). The Composite International Diagnostic Interview and the Structured Clinical I...

The validity of the Michaelis-Menten-Briggs-Haldane approximation for single enzyme reactions has recently been improved by the formalism of the total quasi-steady-state approximation. This approach is here extended to fully competitive systems, and a criterion for its validity is provided. We show that it extends the Michaelis-Menten-Briggs-Haldane approximation for such systems for a wide ran...

It has long been argued that social withdrawal in early childhood is a risk factor for later socioemotional difficulties. However, in recent years, researchers have begun to make distinctions between types of social withdrawal in young children, including shyness, social disinterest, and social avoidance. In this article, we review the literature on multiple forms of social withdrawal in early ...
