This is the umbrella repository for all materials related to the Fedorenko Lab "Understanding Jokes" project. It corresponds to [this paper](https://psyarxiv.com/h2nyx/) (PsyArxiv version, 7/23/18). The repository contains a series of components (sub-repositories), which can be seen off to the right of this wiki; the full list of files across all components can also be expanded below (in 'Files'). Here is the full list of components (described briefly, check individual components for more details). ## Preregistration Document This project consists of two studies; the second is an exact replication of the first, with a larger sample size and one additional localizer task included. The second study was preregistered prior to collecting the data; the registration itself is available at [this link](https://osf.io/k3m7b/). It contains a complete description of the data to be collected, sample sizes, data exclusion rules, and confirmatory statistical tests. ## Study Materials The stimuli and presentation scripts for all tasks used across scanning sessions for both Study 1 and Study 2. The only exception is the video file for the 'Cloudy' localizer, which we are not licensed to share. ## Localizer Masks Whole-brain maps of the masks used for functional localization (LH Language/RH Language homologues, Multiple Demand, Theory of Mind.) ## t and con maps All individual whole brain maps (per person/task/contrast) used to calculate the values reported in this paper. ## Analysis - Study 1 This repository contains an analytic pipeline for producing the results of Study 1. It can be used to verify the calculation of mean fROI values from whole-brain images by task, contrast, & participant; these analyses are conducted on the EvLab cluster (MindHive) and have not been testing out of that environment. It *could* also be used to verify the pipeline from mean ROI values to statistical test results, but (primarily for error checking when presenting Study 1 & 2 results side-by-side) recommend using the pipeline for Study 2 to see these instead. ## Analysis - Study 2 This repository contains a reproducible pipeline that reads from (for Study 1) fROI activations by task, contrast, & participant or (for Study 2) from whole-brain images by task, contrast & participant, all the way through to the figures and all statistical tests that are included in the final version of the manuscript. As with Study 1; producing the mean fROI values requires (right now) access to the MindHive cluster (please email mekline@mit.edu if you need this); but all figures and analyses from these values can be produced from the script. ## Preprint A link back to the preprint for this manuscript!
