ProgramsI have created several data analysis programs that are freely distributed on my website (http://sites.williams.edu/kev1/programs):

1. Kwik Score – Scores large sets of free recall data (e.g., 2000+ participants) in seconds.

2. ARC Scorer – Scores free recall data and calculates ARC scores (see Roenker, Thompson, & Brown, 1971) for categorized materials.

3. Pair Frequency Scorer – Scores free recall data and calculates PF scores (see Sternberg and Tulving, 1977) for unrelated materials.
