Reproducing this project

The preregistration for this project is at https://osf.io/5qz7v

The overall manuscript can be reproduced by knitting manuscript/manuscript.Rmd

  • This file reads data from data/combined_data.csv and data/boyce_2023_data.csv
  • This file uses code/helper/parse_stats.R

data/combined_data.md has clickable links to the write-ups, pre-registrations, and projects (code/data) for the replications and rescues. If you are looking at OSF, data/project_links.pdf has clickable links. If you download the repo, data/combined_data.xlsx has clickable links.

Note that links contained within the project write-ups on RPubs may not open directly and you need to right click them to open in a new tab (due to security features of osf and github).

Additionally, the project repos are contained in first-replication-projects and individual-rescue-projects. Archival copies of the write-ups are in first-replication-reports and individual-rescue-reports (download/clone the repo and then open the html files in a web browser to view them).

The numeric results in data/combined_data.csv (effect size measures, sample sizes, number of trials) were coded off of the papers and reports. Where the effect size measures were not presented in the needed format, recalculations were done (see reconstruct_effect_sizes for data and code for these).

Folder structure

Code

  • initial_criteria.R describes the process for determining which projects were eligible for rescue
  • process.Rmd is a draft analysis script
    • it pulls the coded data from our google sheet and merges it with study-level variables from Boyce 2023 replication data to write data/combined_data.csv
    • it checks that we don't have parsing errors in our data format
    • it does analyses (those in the manuscript have their analysis duplicated in manuscript/manuscript.Rmd)
  • helper/parse_stats.R parses our raw effect size format and calculates standardized effect sizes and helper/stats.R wraps p_original and prediction_interval functions (used by process.Rmd but not manuscript.Rmd)

Data

  • combined_data.csv is the raw data coding sheet with links to pre-registrations, etc
  • combined_data.md is a version of combined_data that renders with clickable links on github
  • parsed_data.csv is a saved intermediate that has the results of parsing effect sizes and computing standardized effect sizes
  • boyce_2023_data.csv is a copy of data from Boyce et al 2023 which reports on the first replications

Manuscript

  • manuscript.Rmd is the manuscript, with analysis code embedded
  • manuscript.pdf is the result of knitting manuscript.Rmd
  • 251rescue.bib is the bibliography
  • apa7.csl, generic_article_template.tex are helper files for formatting the manuscript
  • coverletter/, title_page.Rmd, and manuscript_anon.Rmd are leftovers of the submission process

First-replication-projects and Individual-rescue-projects

  • include the individual replication and rescue projects (aka github repos) respectively
  • the rescue projects repos have been checked and include data, code/reproducible report, and the materials to run the experiment

First-replication-reports and Individual-rescue-reports

  • archival copies of the reports from individual projects, in case the rpubs links break or are overwritten
  • to view, download the repo and open the html files in a browser Find links to the live versions at data/combined_data.md. Note that links contained within the project write-ups on RPubs may not open directly and you need to right click them to open in a new tab (due to security features of osf and github).

reconstruct_effect_sizes

In a few cases, the effect size information we needed for comparable SMDs was not available from published papers or project write-ups, and we had to construct it.

  • schectman_es.Rmd calculates the effect size for the original Schechtman et al. The original paper reports a p-value but not exact values, but the authors were kind enough to send their matlab data files. This uses the three DataTest*.mat files. Additionally, we looked at the rescue data to recalculate trial counts (subject_data_final_full_processed.csv)
  • Denis et al is an additonal replication of Payne et al 2008; however the analysis reported in the paper is not the same as the analysis Payne et al used. Luckily data was available, so we calculate the corresponding result in denis_es.Rmd using data in Expt1_OverallRecognition.csv and Expt1_SpecificRecognition.csv.
  • For Hopkins et al, the main effect of interest is a coefficient in a linear model. However, coefficients cannot be converted to SMD easily, so we calculate the mean and sds instead in hopkins_es.Rmd. The original data is in hopkins_raw.csv, the replication and rescue data is sourced from their github repos.
