Parallel Episodic Processing (PEP) Model
Version 1.1.0


SOURCE FILES

Source files are formatted with four tab-delimited columns of integers (0 to n-1).
These columns, in order, represent:
(1) correct response - technically, this should always be exactly the same as the
     value in the targets column, unless other changes have been made to the
     model to allow for something other than 1-to-1 colour-response mappings
(2) targets
(3) distracters - muliple distracting columns possible
(4) condition - multiple condition columns possible


MAIN.JAVA VARIABLES

To change from the high/low PC to the medium PC run, all that needs to be changed
is the "source" name: "ispcA.txt" for the former and "ispcB.txt" for the latter.
Other variables can be changed to simulate other paradigms. All of these variables
are set in the "VARIABLES" section of Main.java. Some key ones are:

(1) source (String) - Filename where condition information is saved
     (ispcA.txt and ispcB.txt are included with the download)
(2) numSubjects (integer) - Number of "subjects" to run (default = 1000)
(3) numBlocks (integer) - Number of blocks per subject
(4) numResponses (integer) - Number of responses (normally the same as numColours)
(5) numTargets (integer) - Number of colours
(6) numDistracters (integer) - Number of words
(7) isConflict (boolean) - Determines whether words conflict (true) or do not
     conflict (false)
(8) nPerVar (integer) - Number of conditions (multiple variables possible)

Below are the values used for the Schmidt (2011) simulation:

High/low PC:
 source = new String("ispcA.txt");
 numSubjects = 1000;
 numBlocks = 15;
 numResponses = 4;
 numTargets = 4;
 numDistracters = {4};
 isConflict = true;
 numPerVar = {2,3};

Medium PC:
 source = new String("ispcB.txt");
 numSubjects = 1000;
 numBlocks = 15;
 numResponses = 4;
 numTargets = 4;
 numDistracters = {4};
 isConflict = true;
 numPerVar = {2,3};


RUNNING A SIMULATION

After setting your variables in Main.java, you can run the main project. You
should be using a software development kit (SDK), such as the Java Development
Kit (JDK), and an integrated development environment (IDE), such as NetBeans.
It is important that your source file is with your java class files so that the
compiler can find the trials that it will present to the model. Running the
project will cause the model to simulate all participants with a different random
trial order. The model will also create a tab-delimited text file called
Means.txt that will contain the mean response time and percentage error for each
participant in each condition. This is created by DataAnalysis.java and can be
run independently of the rest of the model. Note that any simulation results that
you want to keep should be removed from you source folder before starting a new
simulation run, as new datafiles will overwrite old ones.
