Automated Operation Span Task

It is definitely possible, although it sounds like a fairly complex task to code (compared to more standard tasks).

To try it out, I would first code the simplest version, one where you have 3 math problems (and thus 3 letters to remember)

For each math problem, depending on whether you need complex math symbols, you could use "show bitmaps math problem" or alternatively you could spell it out as text (your example math problem is simple)

How do you actually know that people have solved the math problem (or do they not need to?).

For the 3 math-problem task, I would do something like this. This should work. You can add more details, such as correctness and reaction times in the save line:

NOTE: On each table line, you first have 3 math problems, then the three keys as strings, and then the three associated numbers of keys being pressed
You can make a table with multiple problems, you would do that probably in word or so and then later cut and paste. Or

table my_table3
"(2 x 2) -1" "5 + 3x = 35" "(4 x 4) -2" "k" "a" "m" 1 2 3


task three_math_problems
table my_table3
keys k a m # whatever keys are required
### PROBLEM 1
show text @1 0 -100 255 255 0
delay 5000
show text @4 0 100 200 255 200
delay 2000
clear -1 -2
### PROBLEM 2
show text @2 0 -100 255 255 0
delay 5000
show text @4 0 100 200 255 200
delay 2000
clear -1 -2
### PROBLEM 2
show text @3 0 -100 255 255 0
delay 5000
show text @6 0 100 200 255 200
delay 2000
clear -1 -2
### NOW READ KEYS
show text "Now enter keys in order"
readkey 7 5000
set $key1 KEY
show rectangle 0 0 20 20 100 100 255
readkey 8 5000
set $key2 KEY
show rectangle 40 0 20 20 100 100 255
readkey 9 5000
set $key3 KEY
save $key1 $key2 $key3



show rectangle 80 0 20 20 100 100 255

Were any of you able to find an implementation of the operation span task on psytoolkit? If you ended up doing it yourself, would you mind sharing your code?

Anyone who is interested in setting up a classic working memory span task please contact me via psytoolkit@gmx.com and I am happy to work together with you on implementing it. It should not be very difficult to do.
