In the present paper behaviors of mentally retarded children were recorded simultaneously on real time and time lapse video recorders. Behaviors on the time lapse recordings occurred at a rate 12 times faster than they actually occurred in real time resulting in a 92 percent reduction in the time required to score the tapes. Reliability estimates from real time and time lapse records were high and correspondence between the two methods was good. The limitations of time lapse and the feasibilities for the extended use of time lapse video recorders in behavioral and ecobehavioral assessment of mentally retarded individuals are discussed.
在本论文中，对智障儿童的行为使用实时录像机和延时录像机同时进行记录。延时录像中行为发生的速度比实际实时发生的速度快12倍，从而使录像评分所需时间减少了92%。实时记录和延时记录的可靠性评估都很高，两种方法之间的一致性良好。本文还讨论了延时录像的局限性以及在智障个体行为和生态行为评估中更广泛使用延时录像机的可行性。
