Conclusions These initial results demonstrate feasibility. More study is needed. The instrument was poor, and not sufficiently adapted to the age of the children. There was much confusion, especially in the inner city group. Negatively worded questions were especially problematic. The sample size was small - and reduced dramatically when a third of the data were contaminated and needed to be discarded. There was no comparison made with alternate interventions that might afford a similar change less expensively. This is a benefit of the Yuker instrument: a large body of data exists testing the effect of such technologies as motion pictures, etc. A follow up study that determines whether there was any lasting effect is certainly in order. Conversely, the effect of prolonged play also merits study. Five minutes is not realistic.
