SOMA: Shared Organization Metric Analysis (SOMA)

In ggreeley/MemoryOrg: (A Few) Retrieval Organization Metrics for Human Memory Research

Description

Adapted from Congelton & Rajaram (2014). Computes SOMA for a triad (three individuals). Computationally equivalent to PF but assesses pairs across multiple individuals instead of within the same individual's multiple recall phases.

Usage

SOMA(resp_A, resp_B, resp_C)

Arguments

resp_A	Character vector containing items (word responses) produced by Person A
resp_B	Character vector containing items (word responses) produced by Person B
resp_C	Character vector containing items (word responses) produced by Person C

Examples

resp_A <- c("king", "palace", "forest", "poem")
resp_B <- c("walnut", "sorrow", "mountain", "game", "forest", "poem")
resp_C <- c("forest", "game", "bank", "mountain", "walnut", "sorrow")

SOMA(resp_A, resp_B, resp_C)

Or with example data SOMA_test and SOMA_test_intrusion (adapted from Sternberg & Tulving, 1977):

SOMA(SOMA_test$A_response, SOMA_test$B_response, SOMA_test$C_response)
SOMA(SOMA_test_intrusion$A_response, SOMA_test_intrusion$B_response, SOMA_test_intrusion$C_response)
