How valid and reliable is this study? Why?
This experiment tests the hypothesis that background, adult television is a disruptive influence on very young
children’s behavior. Fifty 12-, 24-, and 36-month-olds played with a variety of toys for 1 hr. For half of the hour,
a game show played in the background on a monaural TV set. During the other half hour, the TV was off. The
children looked at the TV for only a few seconds at a time and less than once per minute. Nevertheless, background
TV significantly reduced toy play episode length as well as focused attention during play. Thus, background
television disrupts very young children’s play behavior even when they pay little overt attention to it. These
findings have implications for subsequent cognitive development.
