On the 10th trial, Sarah s mother notes that her daughter is watching her friends through a nearby window while the machine is running. Frank painstakingly guides Ted through every step of one of the problems. Once this example has been successfully completed, Frank sends Ted back to his own room to do the next problem on his own.

Her mother reminds her to do so each day for a week and they check a chart together following the test.

After Audrey successfully does the test and checks the chart for two weeks in a row, her mother waits to see if Audrey will continue to test and check the chart.
