We decided to teach these individuals to wash the dishes they had used for
their snack (i.e., a cup, plate, and spoon).Washing dishes was selected as the target
activity because it was a necessary task related to their break-time routine. During
break-time, the participants used a standard set of utensils (i.e., plate, cup, and
spoon) for their snack. Intervention therefore focused on teaching the participants
to wash, dry, and store these items. In addition to these utensils, a sponge, plastic
bottle of dish soap, and a towel were placed to the side of the kitchen sink prior to
each session. A task analysis for washing dishes was selected from the Murdock
Center Program Library (Wheeler et al., 1997). This task analysis was adapted to
make it consistent with the materials available in the kitchen. Table 2 shows the
task analysis used in this study.
Each step of the task analysis was initially filmed as an individual video clip
using a digital camera (SonyDSC-F828 Cyber-shot). Steps 7 and 8were combined
into a single video clip. The clips were filmed from the performer’s perspective.
That is, when participants viewed a video clip, they saw it from the perspective
