Install

please see Psytoolbox-3

• windows

  • Download the Psychtoolbox installer to your desktop.
  • install the 64-Bit GStreamer-1.18.0
  • install the Microsoft Runtime Libraries for MSVC 2015-2019
  • Open Matlab as administrative user (for Windows 7 and later, right-click the Matlab shortcut and “Run As Administrator”) and type the following in the command window, assuming you want Psychtoolbox to be installed inside the C:\toolbox folder:

   >> cd('into the folder where you downloaded DownloadPsychtoolbox.m to').
   >> DownloadPsychtoolbox('C:\toolbox')
  

  • You can also use Octave 6.2.0 for free
  • install octave-PTB3 similar like install PTB at Matlab

• Linux *Matlab

   Terminal
   >> sudo dpkg-reconfigure matlab-support
  

  *Octave & Matlab

  1. If you are using Matlab R2014b or later, go to step 3. For older Matlab versions go to step ii. If you are using GNU/Octave on a Debian or Ubuntu based system, execute this command in a terminal: sudo apt build-dep octave-psychtoolbox-3 and then go to step ii.
  2. If you are using Octave on a different Linux distribution (unsupported by us, although it will probably work on many!) then you will need to track down and install various runtime dependencies manually.
  3. Install the subversion package from your Linux distribution’s archive (e.g. apt-get install subversion, or yum install subversion, et al.). If you are using Octave, go to step iv For Matlab, continue to step iii.
  4. On a Debian or Ubuntu based system, quit Matlab, and install the matlab-support package by typing sudo apt install matlab-support into a terminal window. When it asks you for the location of your Matlab installation, tell it. When it asks you if it should rename some Matlab libraries to fix Matlab compatibility issues, answer YES, otherwise hardware accelerated graphics will likely not work later on!
  5. If the matlab-support package was already installed before you installed Matlab, or after each update of Matlab, run sudo dpkg-reconfigure matlab-support to rerun this fixup script, as described in the previous sentence, othewise hardware accelerated graphics will likely stop to work!
  6. Start your Octave or Matlab, cd into the folder that you saved the DownloadPsychtoolbox.m script in, and run (replace /home//toolbox/ by a folder of your choice!):

   >> DownloadPsychtoolbox('/home/foo/toolbox')
  

Parameter

• output_folder the output folder name (default CS)
• key_<num> the four answer keys (default Z X C V)
• continueCondition how many question continue right will go to next rule (default 6)
• numTrials the most trials in the test (default 48)

image

image all other components will be used question select cards as question cards and name <color><shape><number>.png 24 select cards have only one atribute as same as the Answer cards cardArray a matrix for record all select cards atributes 111.png 222.png 333.png 444.png the Answer cards

Execute the test

0. Run MCST if you use Octave please use MCST_octave
1. Press any key to begin
2. Question cards at lower left and four Answer cards at the upper right
3. choose one Anwser cards if this card not have any Question card atributes, zero as the rule number means the rule not descide
4. the Question cards from the select cards have random order and all select card can arise twice
5. all test have 2 round and the first rule is descided by the subject and than random rule order for left two rule
6. if the rule order is 1→2→3 in the first round the second round will be 1→2→3
7. if the subject meet the continue condition on the roll it will go to next rule
8. If 2 round test is finished, it is finish and the screen pops out "press any key to end"

Output file

---

• this test will output a CSV file in <output_folder>_<number>

• CSV file name is exp_<date>.

• CSV header

Rule	Atribute_1	Atribute_2	Atribute_3	Resp	RT	Correct
0 to 3	Color	Shap	Number	1 to 4	Second	0 or 1

• Atribute & Rule order

Atribute & Rule order	1	2	3	4
1.Color	Red	Green	Blue	Yellow
2.Shape	Circle 🔘	triangle 🔺	Cross ➕	Stars ✴
3.Number	1	2	3	4
* 0 not decide rule	😊	Smile mens answer is right.	🙁	Sad means answer is wrong.

Troubleshooting

• At Linux system the hint sentence of MCST start and finised may disappear. If the window is all black just press any buttons that will continue execute the test.
