Continue Progressive X Keyword

<ContinueProgressiveX>
<cpx>
<cp>


    This keyword is used for word by word sentence reading tasks replacing the need to use the Response Contingency keyword. This keyword allows <ProgressiveX> to be used across items, where the first item uses <px> and following items that need to continue spacing where the previous item finished use <cpx>. Both <px> and <cpx> only need be used once at the beginning of an item.

    For example, the old form of word by word sentence reading would be:

1 <px .1> + "hickory " / - ! "dickory " / + ! "dock " / + ! "the " / + ! "mouse " / + ! "ran "/ + ! "up "/ + ! "the " / + ! "clock";

    This would produce responses for items 1 to 9. The new form, while more expansive sticks to standard constructs and explicitly shows which frame produces which RT:

+1 <px .1> * "hickory ";
-2 <cpx> * ! "dickory ";
+3 <cpx> * ! "dock ";
+4 <cpx> * ! "the ";
+5 <cpx> * ! "mouse ";
+6 <cpx> * ! "ran ";
+7 <cpx> * ! "up ";
+8 <cpx> * ! "the";
+9 <cpx> * ! "clock";
   
    Other keywords that are likely to be used in conjunction with <px> and <cpx> are <Delay 0>, <ContinuousRun> and <NoFeedback>. Should scrambling of item files be required the <VariableGrouping> keyword will allow you to deal with sentences with different numbers of words in them.
