Readme Free Recall & Final Free Recall Data

Overview: There are two folders: Scripts and Data. In the Data folder there are two data files stored in Matlab format (.mat). They include all of the data needed for running the analyses described in the paper. In the Analysis folder are all of the scripts for the analyses described in the paper

Data files in data folder

1. Sem_matrix- Matrix with semantic similarity values of all 360 words used throughout the experiment.

2. RK_PData- has all of the data, words presented, recalled, judgments made etc.

In recall and presentation matrices, each row is a single list, and words are numbered from 1-360 with the same numbering as used in Sem_matrix (i.e word 57 corresponds to row 57 in Sem_matrix).

Description of fields in RK_PData:

1. RecItems: Items recalled during free recall. 0/negative numbers are errors or items not recalled.

2. PresItems: Matrix w/items presented during free recall.

3. RespMat: Subject’s encoding response to each item presented (abstract = 1, concrete = 2).

4. R_mask/K_mask: “1” represents “R” or “K” judgment respectively during Free Recall. Note that these masks also include responses for errors.

5. FFR_Rec: items recalled during Final Free Recall. Items are represented by absolute index numbers(1- 360). 0/negative numbers are errors or items not recalled.

6. FFR_R_mask/FFR_K_mask: “1” represents “R” or “K” judgment respectively during Final Free Recall. Note that these masks also include responses for errors.

Description of scripts:

List of Scripts:

Scripts call upon various functions that are in subfolder “functions” (If folder is moved path needs to be changed within the script). All functions have comments and description within their file

1. FactorAnalysis: Extracts data for Free Recall from RK_PData, and creates Sub_Factor that stores the data. Includes analysis such as lag-crp, sem-crp, and more.

2. FFR_factor_analysis: Framework script, extracts data for Final Free Recall from RK_PData, and stores in Sub_Factor.

3. Test_FFR_Temp_attention_confound.m: Examines whether temporal scores result from list positions (analysis described in supplemental materials).

4. Quadratic_recency- Script for analyzing and plotting the quadratic function of recency
