This tab is used to set the default settings for each new Empty stimulus in the Stimulus List. For example, the default setting for all stimuli is Number of repetitions of each stimulus=1. Suppose you want to create a research model that involves the presentation of 20 different stimuli, but you want each of them to be presented 3 times. Without default settings, you would have to change the Number of repetitions of each stimulus setting 20 times to the value 3. An alternative is, before starting to create a new research model, set the default value for this setting to 3. So, the default settings reduces your time to creation of new research models. It is important that you set all default settings before creating a new research model, as they do not affect already created stimuli. All other default settings that are not present in this Tab are available by double-clicking on the selected file (or Stimulus) in the Stimulus List, find the desired setting there, enter a new value and then check the Set as default checkbox. This is best done after inserting the first file into the Stimulus List. After that, the application will remember the selected setting and set the newly selected default value for each new file.
After confirmation, all the default values that you previously set will be reset to the initial values, i.e. those values that appeared when the application was started first time. After reset, this window will close. You can then open it again with the default settings loaded.
Type a new default value for this setting. The newly set default value applies to all new empty stimuli in the Stimuli List.
All registered reaction time values that are less than this set value (in ms) are considered a premature reaction for that stimulus. The error flag for that stimulus is incremented by a value of 2. Since the total error must be 0 for the reaction time to be valid, 0 points are automatically assigned for that stimulus.
Type a new default value for this setting. The newly set default value applies to all new empty stimuli in the Stimuli List.
As the first stimulus starts only after the user presses any keyboard key except ESC (thus signaling to the application that it is ready for the first stimulus in the sequence), here you can enter the delay time ONLY FOR THE FIRST stimulus from the Stimulus List.
Here you can enter the time after the presentation of the last stimulus from the List of stimuli. You can, for example, shorten this time so that the user does not press the keyboard key ESC after the presentation of the last stimulus in the sequence. We warn you that prematurely pressing the ESC key can lead to the loss of the storage of research results.
After displaying each stimulus, the application will wait this time (in ms) for the user to press a key on the keyboard. When this time passes and the user has not pressed a key on the keyboard, the default error flag is set: no reaction at all. 0 points are assigned for that stimulus and the error flag is set to 1. Note that the application ignores all keys that are not in the list of keys: Forbidden (error) keys. Tip: if you use (large) audio files, especially if you use parallel playback of many audio files, set this parameter to a large value, because the application will lag behind real time. Otherwise, the user will not have enough time to react.
Also see other settings you can adjust globally for all stimuli within your research model: Generator, Instructions, Layout, Resolution, Cumulative.
You must respect the warning Allowed range of values is. Otherwise, the newly set value will be discarded without any warning when closing this window.
Here you can enable or disable Autocorrection for displaying images (it only works for visual stimuli). If Autocorrection is on, the display time of images on the screen is adjusted to the currently selected Refresh rate of the computer monitor. Click on the Calc button to see how autocorrect works.
If you do not want to save the changed settings within the Option Window, you must explicitly click on the Cancel button when closing this window. Closing this window with "x" (Close) or Save and Close , automatically saves all (changed) values.
