Hello
I am currently working on a non-adaptive N-back task and want to check if the test subject has given the correct answer. But different to the original N-back task the test subject has to answer with the position of a figure N trials before instead of just checking if the figure is the same.
The programm shows always the same blue square but in different positions: top-left, top-right, bottom-left, bottom-right. The test subject than has to tip the positions of the square 2 or 3 trials before into the keyboard:
W --> (17) --> top-left
O --> (24) --> top-right
A --> (30) --> bottom-left
L --> (38) --> bottom-right
By now, this is the code i have:
Pictures:<picture Nback_trainingsquare1Selection>
/ items = Nback_trainingsquare1
/select = 1
/size = (100%, 100%)
</picture>
-->the same for the other 3 square-pictures
Trials:<trial training1>
/ stimulustimes = [0 = Nback_trainingsquare1Selection; 0 = Abbruch; 500 = erasertraining; 500 = Abbruch;]
/ validresponse = (noresponse, 30, 38, 17, 24)
/ responsetime = 0
/trialduration = 2500
</trial>
--> the same for the other three suares
Block, 2-Back:
<block TrainingOld_2back_Nr1>
/ onblockbegin = [ values.N = 2;
values.currenttarget = 0; values.minus1 = 0; values.minus2 = 0; values.minus3 = 0; values.minus4 = 0;
values.TotalBlocks = values.TotalBlocks + 1;
values.starttrialcounter = 0;
values.repetitioncounter = values.repetitioncounter + 1;
]
/ trials = [1 - 121 = noreplace(training1, training2, training3, training4)]
/ screencolor = (0, 0, 0)
/ skip = [radiobuttons.agegroup.response!="2"]
</block>
Block, 3-Back:
<block TrainingYoung_3back_Nr1>
/ onblockbegin = [ values.N = 3;
values.currenttarget = 0; values.minus1 = 0; values.minus2 = 0; values.minus3 = 0; values.minus4 = 0;
values.TotalBlocks = values.TotalBlocks + 1;
values.starttrialcounter = 0;
values.repetitioncounter = values.repetitioncounter + 1;
]
/ trials = [1 - 121 = noreplace(training1, training2, training3, training4)]
/ screencolor = (0, 0, 0)
/ skip = [radiobuttons.agegroup.response!="1"]
I hope that someone can help me, thank you! :)
