Duration (seconds) of speech across the five tasks

Task	Mean	SD	Range
Routes	55.62	11.08	36 –75
Landmarks	58.23	7.76	43 –70
Film plots	58.14	7.92	43 –70
Film frames	56.36	8.78	36 –68
Baseline number repetition	63.86	6.23	53 –76

Means were calculated across the 22 scan acquisitions (two per subject) for each of the five tasks after data were digitally analyzed. Means represent the number of seconds when speech output occurred during the total 90 sec of scan acquisition.
