If you study memory, you probably use free-recall tasks and analyze participant outputs. If your to-be-recalled items belong to categories, this project hosts tools that have been useful for analyzing participant outputs from free-recall tasks. Currently, it includes two main tools that I've repeatedly used, with the potential for more to be added in the future.
Code: R script
Web App: Clustering in Recall Index Calculator
This tool calculates four different indexes of clustering in free recall (ARC, RR, MRR, DS) for an entire dataset, which should be coded according to categories (based on Otani and Senkova, 2012). Visit the web app or refer to the comments in the code for instructions on usage and references to relevant papers.
Code: R script
Web App: Recalled pairs calculator
This tool counts how often each possible pair exists in a sequence of multiple categories. For example, if your to-be-recalled items belong to three categories (coded as 1, 2, and 3), this app counts, per participant, how often all possible pairs (11, 12, 13, 21, 22, 23, 31, etc.) occur. Visit the web app or check the comments in the code for instructions on usage.
