Switch Task (MMY4, SPA)

also known as nBMSI n-Back Multi-Source Interference

On the behavioral task computer, open Matlab (as of 2023-11-30 this is still Matlab2015 on 32bit windows.)

Practice for lunaid 12345 looks like

cd C:\Users\localadmin\Desktop\SPASwitch_Cog_Inf
nBMSI 12345 green practice
nBMSI 12345 red practice
nBMSI 12345 in/cog1 practice

and actually running like

cd C:\Users\localadmin\Desktop\SPASwitch_Cog_Inf
nBMSI 12345 green
nBMSI 12345 red
nBMSI 12345 in/cog1
nBMSI 12345 in/cog2
nBMSI 12345 in/cog3
nBMSI 12345 in/cog4
nBMSI 12345 in/cog5
nBMSI 12345 in/cog6

An error may move matlab's working directory to the wrong path (esp. into private). You'll get the error

Undefined function or variable 'nBMSI'.

To fix, cd to the correct directory

cd C:\Users\localadmin\Desktop\SPASwitch_Cog_Inf\private
