This OSF project contains several folders. The **analyses** folder contains all the files needed to learn how to sample from both the individual SDT Threshold model as well as the Hierarchical SDT Threshold model. The **parameter recovery study** folder contains all the files needed to replicate the parameter recovery studies mentioned in the paper. Further information about running the R scripts can be found in [README.txt][25]. ## Main Analyses This folder contains the following files: **SDT Threshold Model for Individuals** - [SDT_samplingScript.R][1]: This is the R code that replicates sampling from the SDT Threshold model for one individual. The script allows you to either use simulated data or the [PratteData.txt][2] data set. - [SDT_model.txt][3]: This file contains the SDT threshold model that we used expressed in the BUGS modeling language. - [SDT_simulation.R][4]: Contains a function that allows you to generate data from the SDT threshold model. - [SDT_graphModel.pdf][5]: A graphical representation of the SDT threshold model. **Hierarchical SDT Threshold Model for Groups** - [HierSDT_samplingScript.R][6]: This is the R code that replicates sampling from the Hierarchical SDT Threshold model. The script allows you to either use simulated data or the [PratteData.txt][7] data set. - [HierSDT_model.txt][8]: This file contains the Hierarchical SDT threshold model that we used expressed in the BUGS modeling language. - [HierSDT_simulation.R][9]: Contains a function that allows you to generate data from the Hierarchical SDT threshold model. - [hierSDT_graphModel.pdf][10]: A graphical representation of the hierarchical SDT threshold model. - [hierSDT_PratteDataSamples.Rdata][11]: Contains the samples from the hierarchical SDT threshold model fitted on the [PratteData.txt][12] data set. **Data** - [PratteData.txt][13]: This is the data from a memory recognition experiment conducted by [Pratte, Rouder, and Morey (2010)][14] that we used in our paper. **Figures** - Most Figures in the paper can be replicated using the script [CreateFigures.R][24] ## Parameter Recovery Study This folder contains the following files: **Parameter Recovery Study for the SDT Threshold Model for Individuals** - [SDT_simSampling.R][15]: Contains the script that does the actual parameter recovery study (i.e., generating data and sampling from the model). - [SDT_simSamples.Rdata][16]: Contains the results from the parameter recovery study. - [SDT_simStudy.R][17]: This script converts the results from the parameter recovery study into a easy to understand plot. - [SDT_simParRecovery.pdf][18]: A graphical representation of the parameter recovery study. **Parameter Recovery Study for the Hierarchical SDT Threshold Model for Individuals** - [hierSDT_simSampling.R][19]: Contains the script that does the actual parameter recovery study (i.e., generating data and sampling from the model). - [simHierSDT.R][20]: Contains a function that allows you to generate data from the Hierarchical SDT threshold model. - [hierSDT_simSamples.Rdata][21]: Contains the results from the parameter recovery study. - [hierSDT_simStudy.R][22]: This script converts the results from the parameter recovery study into a easy to understand plot. - [hierSDT_simParRecovery.pdf][23]: A graphical representation of the parameter recovery study.
