Software
Below are some of the software packages developed in the Cohen Cognition Lab
R Packages
To install the packages in R, first install “devtools” as follows: install.packages(“devtools”)
RRW
A Robust Random Walk r-package that Dr. Cohen developed to instantiate the assumptions of Psychological Value theory.
To install in R:
devtools::install_github(“ccpluncw/ccpl_R_RRW”)
chutils
A utility r-package that Dr. Cohen developed to facilitate programming other packages.
To install in R:
devtools::install_github(“ccpluncw/ccpl_R_chutils”)
chValues
GitHub Link
An r-package that Dr. Cohen developed with the functions required to process raw Psychology Value data.
To install in R:
devtools::install_github(“ccpluncw/ccpl_R_chValues”)
chMorals
An r-package that Dr. Cohen developed with the functions required to relate Psychology Value data to choice data.
To install in R:
devtools::install_github(“ccpluncw/ccpl_R_chMorals”)
SmartGrid Search
A smart grid search optimization r-package that Dr. Cohen developed. This is used to optimize the parameters of simulations when fitting to behavioral data.
To install in R:
devtools::install_github(“ccpluncw/ccpl_R_smartGridSearch”)
QCEB
A utilities package to create the necessary files to run experiments using the QuinlanCohenExperiment suite that runs experiments over the internet (not yet open sourced).
To install in R:
devtools::install_github(“ccpluncw/ccpl_R_QCEB”
Other Software
Cohen Ray Number-Line Task
The Cohen Ray number-line task provides experimenters a quick and easy tool for presenting and collecting data on the bounded and unbounded number-line task with all the controls we use in our lab.
