Recall Phase
++ After all the numbers in a given trial have been presented to you it is your turn: type in the numbers you + remember seeing backwards. It is important to remember to type them backwards, + that is, if you saw 21 33 54, then you should type first 54, then 33, and then 21. The program will ask for + one number at a time (the message "Number 1: " etc) and you must type it in and press enter to submit it. +
