Interpret Key Status Data

In my program, I have a table like this:

table MyTable2

SS2_C101 SS2_C102 1 "Setsize2"

SS2_C201 SS2_C202 1 "Setsize2"

SS2_C301 SS2_C302 1 "Setsize2"

SS2_C401 SS2_C402 1 "Setsize2"

SS2_S101 SS2_S102 2 "Setsize2"

SS2_S201 SS2_S202 2 "Setsize2"

SS2_S301 SS2_S302 2 "Setsize2"

SS2_S401 SS2_S402 2 "Setsize2"



And a task like this, where I’m hoping save @3 could represent the correct response (1 for change and 2 for no change), save KEY could represent the participant’s response (1 for change/pressed A and 2 for no change/pressed L), whereas save STATUS could represent the accuracy (1 for correct and 2 for incorrect).

task MyFirstTask

keys a l

table MyTable2

show bitmap background

delay 2000

show bitmap @1

delay 100

clear -1

delay 900

show bitmap @2

delay 2000

clear -1

font arial

show text "Press A if detected change，Press L if no change"

readkey 2 10000

save BLOCKNAME TABLEROW @4 @3 KEY STATUS RT



However, my downloaded data look like this.

MyFirstDataBlock 16 Setsize4 2 2 1 320

MyFirstDataBlock 12 Setsize4 1 1 2 542

MyFirstDataBlock 2 Setsize2 1 2 1 301

MyFirstDataBlock 11 Setsize4 1 2 1 332

MyFirstDataBlock 7 Setsize2 2 2 1 361

MyFirstDataBlock 24 Setsize6 2 1 2 329

MyFirstDataBlock 32 Setsize8 2 2 1 289

MyFirstDataBlock 28 Setsize8 1 1 2 272



From my understanding, if the correct response and the participant’s response are the same, then the STATUS/accuracy would be 1, whereas if they are different then the STATUS would be 2. Could you share some insights with me regarding what’s the best way to interpret the data or what’s a better way of designing it?



Thank you so much in advance!
