The files presented here replicate the analysis of "Further Evidence for Discrete-State Mediation in Recognition Memory" by Kellen, Singmann, Vogt, & Klauer (2015).
The following files are present:
1. `analysis-script.R`: This commented `.R` file performs the analyses reported in the manuscript and produces all the numbers given in the text, Table 1, and Figures 4 and 6 (this is the main file). It requires the files listed below as numbers 2 to 8 (or the zip file).
2. `words-data.txt`: Provides the data of the word session.
3. `pics-data.txt`: Provides the data of the picture session.
4. `words.sdt.model`: `MPTinR` model file containing the UVSD model for the word session.
5. `pics.sdt.model`: `MPTinR` model file containing the UVSD model for the picture session.
6. `mpt-models.R`: `.R` file containing the likelihood functions for the 2HT models for word and picture session.
7. `mm.words.rda`: Binary R data file providing the $G^2$ values obtained in the mimicry analysis of the word session.
8. `mm.pics.rda`: Binary R data file providing the $G^2$ values obtained in the mimicry analysis of the picture session.
9. `words.mimicry.R` commented R script that performs the (lengthy) model mimicry analysis for the word condition.
10. `pics.mimicry.R`: same as before, but for the picture condition and not commented.
11. `modeling_details.pdf`: Detailed description of the 2HTM's state-response mapping function as well as details on the linear mixed modeling of the RTs.
12. `kellen_singmann_vogt_kaluer_2015.zip`: zip file containing all of the files above.
