ManyBabies (MB) is a collaborative project for replication and best practices in developmental psychology research. Our goal is to bring researchers together to address difficult outstanding theoretical and methodological questions about the nature of early development and how it is studied.

- People, Committees, & Contributor Dashboard
- Resources (calendar, publications, data validator, OSF, github, etc.)
- Events (workshops, webinars, etc.)
- News and Updates (newletters, publication news, etc.)
- Get Involved (all are welcome, access to an infant lab is not required!)

Projects
The broader goals of ManyBabies come together in a set of collaborative projects. They are organized in main projects (either empirical or methodological), spin-off projects, and secondary analyses. Below is a list of our main projects, together with their affiliated spin-off projects and secondary analyses. More info is available on the Projects page.
Empirical Projects
MB1: Infant-Directed Speech Preference
Do infants prefer infant-directed speech? Do age, method, and native language background matter?Spin-offs: MB1-Africa, MB1B, MB1G, MB1L, MB1N, MB1T, MB1-Demo, MB1-Meta
MB2: Theory of Mind
Do infants show anticipatory looking that reflects the false belief of another agent?Spin-offs: MB-ManyTrackers, MB-ManyWebcams, MB2.2, MB2.3, MB2P
MB3: Rule Learning
Do infants learn and generalize identity-based rules from speech stimuli?Spin-offs: MB3-NIRS, MB3L, MB3P, MB3T
MB4: Social Evaluation
Do infants prefer agents who are seen to help over those who are seen to hinder?Spin-offs: MB4E, MB4I, MB4P
MB5: Hunter & Ames Model of Infant Looking Preference
What factors shape infants’ preferences for familiar and novel stimuli?Spin-offs: MB5-Meta, MB5N, MB5T
MB6: Neonatal and Early Imitation
What is the nature of neonatal infants' imitation of gestures?MB7: Curiosity
How does curiosity guide exploration and learning?MB8: Screen Time
What is the nature of early childhood screen use around the globe, and how is it related to language and socio-emotional development?MB9: Perceptual Specialization
How does perceptual specialization emerge across development, and how is this related to infants' context and experience?Methodological Projects
MB-AtHome: Online Infant Data Collection
Solutions for testing infants in their home, with a focus on measuring looksSpin-offs: MBAH1-LWL, MBAH2-VP
MB-Demographics: Unified Demographics for MB Projects
Creating unified demographic forms for ManyBabies projects, with standardized constructs and templatesAffiliated Networks
