Sample Presentation Keyboard which displays a spatial (picture) stimulus.
REACH Interface Author keyboards can be used to practice or test memory skills. A variety of approaches can be taken, depending, for example, on the type of information being used, the procedure being used, and the retention period (i.e., the time period between presenting the information and being "tested" on it). Memory for numeric, verbal, spatial, or auditory information can be assessed.
One example of such a keyboard included with REACH Interface Author™ is the "memory1.kbd" keyboard. It is typical of many memory tasks used to test spatial memory. Turn on scanning when you try this memory task. In the Presentation Keyboard, a picture of a person wearing one earring is displayed for a period of time (see above picture). The period of time is set by adjusting Scan Time. After the face has been presented, you are asked to operate your switch, causing a Test Keyboard (memory1a.kbd) to appear (see below picture). Your job is to point at each of the squares, study the picture that is presented, and decide Yes (press the key) or No (don't press the key) whether that picture could have been taken at the same moment as the one on the Presentation Keyboard.
Feedback about correct or incorrect responses is provided by associating positive or negative feedback with the Key Pressed key state as appropriate.
