Furthermore, it was examined whether interactive behaviors and complementarity depended on children's externalizing and internalizing behaviors, interaction time, and interaction frequency. A total of 48 teachers and 179 selected kindergartners with a variety of externalizing and internalizing behaviors were observed in a small group task setting in the natural ecology of the classroom. Teachers' and children's interactive behaviors were rated by independent observers. Teachers reported about children's externalizing and internalizing behaviors. Multilevel analyses indicated that both teachers and children reacted complementarily on the control dimension but not on the affiliation dimension. Teachers showed more control and more affiliation toward children with higher levels of internalizing behavior. In addition, teachers displayed less affiliation toward children with higher levels of externalizing behavior, whereas those children did not show less affiliation themselves. Teachers' and children's complementarity tendencies on control were weaker if children had higher levels of externalizing behavior. © 2012 Society for the Study of School Psychology.

Introduction Teacherchild relationships have been found to predict various aspects of children's social and academic school functioning (e.g., Hamre & Pianta, 2001; Hughes, Luo, Kwok, & Loyd, 2008; Peisner-Feinberg et al., 2001). Although in the last two decades the individual teacherchild relationship has often been subject of research, studies in the early school years mostly focus on teachers' global perceptions of the relationship. Fewer researchers used observations to measure teacherchild interactions or teachers' behaviors toward an individual child (e.g., Coplan & Prakash, 2003; DeMulder, Denham, Schmidt, & Mitchell, 2000; Downer, Booren, Lima, Luckner, & Pianta, 2010; Ladd, Birch, & Buhs, 1999; McDonald Connor, Son, Hindman, & Morrison, 2005; Thijs & Koomen, 2008). These observational studies generally used global ratings or time sampling methods that were aggregated to form an overall measure of interaction quality. Observations of reciprocal influences in interactions between teachers and individual children have been scarce.
