text: You will observe a series of objects, one at a time.
  The objects differ along three binary dimensions: shape (square vs. triangle), size (1.50 inch vs. 0.75 inch), and shading (black vs. white).
  Each dimension is indicated by the three digits, for example, '121' means a square, 0.75 inch, black object.
  Based on some combination of the three dimensions, each object belongs to one of two categories, X or J.
  You have to assign each object to one of the two categories by pressing the corresponding key.
  If your choice is correct, you get a point, otherwise you lose a point.
  Your goal is to get as many points as possible.
  At some point, you begin a 'test block' in which you will see eight objects.
  Here, you have to assign each object to one of the two categories as before.
  Furthermore, you have to rate how typical the object is for the category you chose, on a scale from 1 to 9.
  1 means 'not at all typical', and 9 means 'most typical'.
