By use of four buttons in the part of the stimulus edit, the types and timings of stimuli can be adjusted for convenience of the user.
By pushing the add button, the stimulus setting dialog box appears, in which stimulus files and timings can be configured. This button is used when the stimulus setting is configured for the first time or incase it is necessary to configure new stimuli in addition to the ones already existing in the stimulus setting window. The stimulus dialog box can be largely divided into the stimulus file setting, the stimulus repetition setting and the stimulus interval setting.
(I) Stimulus File Setting
When the find file button in the stimulus setting dialog box is clicked, a file open dialog box appears. The user can open and use a wav file for auditory stimulus, a bmp file for stimulus by pictures, an avi file for that by animation, and a txt file for that by characters.
(II) Stimulus Repetition Setting
This part determines how many times a selected stimulus file should be repeated. It is configured into the stimulus setting window as many times as the number entered by the user.
(III) Stimulus Interval Setting
After the number of repetition has been entered, it is necessary to configure the time interval of stimuli on the basis of the initial stimulus. There are two types of interval settings, i.e., periodic and random. For a random setting, the intervals are set at random automatically within the time range configured. In case of a periodic setting, it is set at the regular interval the user enters in the interval setting field. The number is entered in the unit of second. For example, if a 5 has been entered in the interval setting field, the subject will get stimuli every 5 seconds.
If the user wishes to insert a stimulus before another specific stimulus, the insert button is used. Click with the mouse the location to which the new stimulus should be inserted at first and push the insert button next. By pushing this button, the stimulus setting dialog box will appear. Select the stimulus file to insert by use of this dialog box and set the number of repetition and the interval. Then the new stimulus will show up in the stimulus setting window.
This button is used to delete a stimulus that has been already configured from the stimulus setting window. Select the stimulus you wish to delete by clicking it with the mouse and push the delete button. The stimulus will be removed from the stimulus setting window.
This button is used to delete from the stimulus setting window all the stimuli that have been configured.
