3. Stimulus Class Setup: Step 1 When a stimulus class is loaded, a new tab is created for the class. The controls on this class allow various class parameters to be configured. The field is used to refer to the class Name during experiments. The field acts as a numerical identifier for the class and is used to Marker tag EEG data while a stimulus from the class is being displayed. The and fields Question Answer are used to specify the subcategories for stimuli in the class. For example, a faces class might have the person male or and in these fields. Clicking on a “Was female?”, “male”, “female” stimulus in the list of stimuli causes that stimulus to be displayed on the right side of the tab. The drop down list beneath the stimulus can then be used to set the stimulus’s subcategory. Unchecking the checkbox next to a stimulus excludes that stimulus from being used in experiments. 4. Stimulus Class Setup: Step 2 Since specifying the subcategory of hundreds of images is rather tedious, Experimenter provides a tool to assist with this process which can be accessed via the button on the tab. Classify class’s The tool allows the user to run through the images, classifying them one by one in rapid succession. Keyboard shortcuts to the various buttons make this process very efficient. 5. Image Display Configuration After the stimuli are loaded, the next step is to configure how they are displayed. The image display configuration panel contains several controls for this purpose. If the Cycle Through box is checked, the sample images displayed on the right change periodically, which can Images be helpful to determine whether the settings are appropriate. 6.
