Staircases work by specifying the levels that participants have to progress through, and the mechanism by which they can do so

Column name: staircase
Possible values: label and parameters separated by ","
Example staircase:

rowNo	staircase
2	A: start 3, down 1, up 2, correct 2, booster 2, incorrect 1, reversal 3
3	A
4	A
5	A
6	A

Staircase parameters:

Label (important if you want to run two or more staircases in parallel)
Start level (at which level in the staircase should participants start? default=1, "start")
Down step (i.e. increasing difficulty by...? default=1, "down")
Up step (i.e. decreasing difficulty by...? default=1, "up")
Quick down step (that's a "booster" to get the participant quicker to the most interesting area if they are not making any mistakes default=3, "booster")
Correct rule (after how many correct responses in one level does the participant move down? default=2, "correct")
Incorrect rule (after how many incorrect responses does the participant move up? default=1, "incorrect")
reversals (reversals needed to end default=5, "reversal")
trials (after how many trials will the staircase end?, default=50, "trials")
