A child watching an excessive amount of T.V. was provided a behavioral program featuring a token-actuated timer. Earned tokens were used to activate the T.V. for thirty-minute periods. The token-exchange system effectively reduced T.V. viewing and the reductions were maintained at two follow-up points. The principal contribution of the study is the development and evaluation of an electronically controlled device that was used to check the accuracy of parent-reported data.
一个孩子看了过多的电视，我们为他提供了一个包含代币激活定时器的行为程序。挣得的代币可用于激活电视三十分钟。代币交换系统有效地减少了看电视的时间，并且在两个随访点都保持了减少的效果。这项研究的主要贡献是开发和评估了一种电子控制设备，用于检查父母报告数据的准确性。
