PF_all: Paired Frequency (PF with Sub-Measurments)

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

Description

Adapted from Sternberg & Tulving (1977). Computes PF for items between recall trial and trial + 1. In addition to a single PF score, this function also produces the componet measurements of PF including the observed number of pairs of items, expected pairs, common items, and the number of correct items at both trials (assuming intrusions are left as blank cells (NA) - see example data).

Usage

PF_all(resp_1, resp_2)

Arguments

resp_1	Character vector containing items (word responses) produced at trial 1
resp_2	Character vector containing items (word responses) produced at trial 2
