Psychology

Past research suggests that allowing children to make choices (e.g., "Which homework activity do you want to work on next, spelling or math?") produces more positive outcomes than making the choices for the children (e.g., having a tutor decide which homework activity to work on next). Children given the opportunity to make choices exhibited less aggression, fewer tantrums, increased task engagement and completion, less disruptive behavior, and better academic achievement compared to children not given choices.

There were three dependent variables: (1) Challenging Behavior . Note that this last DV was measured only for Wally because initiations were not a problem for the other boy.

Being blind means that the observers were unaware of the purpose of the study and/or the hypotheses. Having blind observers is important in order to reduce the possibility of observer bias. For example, if the observers knew that the children were supposed to be better behaved when given choices versus directive prompts, they may have (consciously or unconsciously) recorded the children's behavior in such a way as to support the hypothesis.
