DONE - 1. To start the experiment: DONE - A. The words “Press the space bar to begin the experiment.” will appear. DONE - B. When the space bar is hit, the following events happen: DONE - 2. At the beginning of a trial, the fixation mark (+) will be appear in the center of the screen. The DONE - mark should stay on for 0.75 seconds. DONE - 3. There should be a brief blank period for 0.25 seconds. DONE - 4. Then, centered where the fixation mark was, 3 words will be presented for 1 second. DONE - A. The words are in all capitals and in 24-point sans serif font and vertically aligned and centered so that the middle word is centered where the fixation mark was. DONE - B. The word is selected at random from the appropriate list of words. DONE - 1. For Trials 1-5, the list is the fruit list DONE - 2. For Trial 6, it is the tool item list DONE - C. Each word (from either list) can be used only once in an experiment. DONE - D. As the participant goes through, capture the word presented and its position in the list. DONE - E. Here is the list of words: Fruits: Pear, Banana, Mango, Honeydew, Watermelon, Orange, Tangerine, Raspberry, Apple, Plum, Peach, Blackberry, Cherry, Grape, Strawberry, Blueberry, Apricot, Cantaloupe Tools: Hammer, Saw, Screwdriver, Nail 5. After the words are presented, a randomly selected three-digit number > 150 will appear: This stimulus is centered in the same font as the words, where the middle word was. The number will be on screen for 1 second. When it is removed, the tracking task from Brown-Peterson will begin. A. When the number is displayed, the delay period begins. The delay will be 15 seconds. During the delay interval the following happens: 1. A tone (1000 Hz for .25 seconds) is presented every .75 seconds to indicate the speed with which the participant should count out loud backward by 3. DONE - B. When the number is removed, the screen begins the tracking task from Brown-Peterson which will last the rest of the delay period (14 seconds). Below is the information from Brown-Peterson repeated: DONE - 1. A dot should appear on the screen moving randomly. The movement should have the following general parameters: DONE - 2. The dot should be 4 pixels wide and circular. DONE - 3. With each update of the screen, the dot should move 4 pixels. DONE - 4. With each update of the screen, the direction of the dot should change randomly +/- 30 degrees. DONE - C. When the dot hits the wall it should bounce off in a reflection manner (angle of incident = angle it comes off the circle). DONE - 1. There should be a square on the screen 25 pixels wide that the participant drags (with their mouse) to keep up with the dot. The square is: DONE - 2. Cyan when the dot is in the square. DONE - 3. Yellow when the dot is not in the square, but less than 10 diameters away. DONE - 4. Red when the dot is more than 10 diameters away. DONE - 5. When the dot moves more than 10 diameters away, another tone (2000 Hz for .5 seconds) should be sounded as well. [If the Brown-Peterson task is changed in anyway, it should also be changed here.] DONE - 6. After the distraction task is completed: DONE - A. There should be three text boxes where participants can enter the three words they remember. They will type the words using the keyboard. DONE - B. Above the three boxes should be: "Recall: Please type the three words you saw, putting one word in each box. Spell the words carefully." DONE - C. These boxes are available for 15 seconds. DONE - 7. After the recall period, there is a 5-second blank screen. DONE - 8. Then repeat Steps 2-7. DONE - A. For the first 5 trials, the words are from the fruit list. DONE - B. For the sixth and last trial, the words are from the tool list. DONE - Primary Independent Variable and levels for default experiment: The primary independent variable is list from which the words are drawn and the trial number (1-6). DONE - Primary Dependent Variable Please capture: the words typed and the words presented and keep it separate for each trial. We will determine the percent correctly recalled (=100*number of words recalled/3) for each trial (we will not collapse over trials). The order of the recall of the words is not to be used in the calculation of percent correct recalled. We could accept common typographical errors for the words unless there is a way to do an automatic spell check.
