🎭 Mooney Faces Task

Welcome to the Mooney Faces Task! This experiment challenges participants to identify faces in black and white images, testing visual perception and face recognition abilities.

🚀 Getting Started

Clone the Repository

git clone --recurse-submodules -j4 git@github.com:belieflab/mooneyFaces.git && cd mooneyFaces && git submodule foreach --recursive 'git checkout $(git config -f $toplevel/.gitmodules submodule.$name.branch || echo main)' && git update-index --assume-unchanged exp/conf.js

Stay Updated

When pulling changes, run:

./sync.sh

🔄 This ensures all submodules are up-to-date.

👌 Pulling changes will not remove any data.

📊 Task Versions

Original Version

• 86 images (half upright, half inverted)
• Participants respond whether the image is a face or not
• Approximate runtime: 8 minutes

Silverstein Version

• 86 main images (half upright, half inverted)
• 20 scrambled images (10 upright, 10 inverted) which act as catch trials
• Additional ratings for perceived age and gender of identified faces
• Approximate runtime: 12 minutes

🎯 Task Procedure

Original Version

1. Participants view black and white images
2. They decide if the image is a face:
   • Press 0 if not a face
   • Press 1 if it is a face
3. Response time: 5 seconds per image

Silverstin Version

1. Same instructions as original version
2. If they decide the image is a face:
   • Press 1 if the face more masculine or press 0 if the face more feminine
   • Press 1 if the face is of a child or press 0 if the face is of an adult

⚠️ Participants must use the numbers at the top of the keyboard, not the number pad
