We study the basic computational processes involved in human language and cognition.

overview: colala's research includes computational and experimental approaches to language acquistion, language processing, and understanding the core features of language. Our work draws on corpus methods, behavioral experiments with adults and children, computational and mathematical modeling, as well as state-of-the-art techniques in machine learning, information theory, statistics, computer science, and linguistics.

We collaborate closely with Tedlab at MIT, The CAOS lab at CMU, The Kidd Lab at UC Berkeley, and The Hayden Lab at the University of Minnesota.

We do fieldwork with an indigenous South American population, the Tsimane' of Bolivia, in collaboration with tedlab and CBIDSI to study universal aspects of human language, numerical cognition, and cognitive development.

philosophy: Most research in colala centers on creating fully-formalized (implemented) theories that aim to address basic questions about human language and cognition with convergent evidence across methods. We work to develop open tools, data, and result, and build an atmosphere that is inclusive, scientifically rigorous, and productive.

topics and selected papers:

• Structured (LOT) statistical learning
  
• Concept learning in language
  
• Cognition in indigenous groups
  
• Communicative language theories

• prospective students •

graduate students: Prospective graduate students should apply to the Department of Psychology at UC Berkeley and contact Steve. Applications are due in in late November. Graduate students should be hard-working, full of ideas, skilled programmers, and capable of self-directed research. Students interested in the lab should bring strong quantitative skills including knowledge of statistics and programming, as well as serious background in some of the following areas: machine learning, mathematics, theoretical computer science, mathematical logic, cognitive development, language acquisition, language processing, or linguistics.

undergraduates: Undergraduates must be independent, creative, self-motivated, and good at programming. Our undergraduate research opportunities include work on current large-scale projects, as well as opportunities for self-directed research. Undergraduates will typically have a background in psychology, math, computer science, or linguistics. Apply here.

• libraries & software •

A number of research software packages are actively developed by colala and available under the GNU Public License:

• LOTlib3 is a Python 3 library for modeling learning complex concepts as compositions of primitives in a language of thought. GPL3


• Fleet is a C++ library with the same goal as LOTlib3, but much faster. This is currently developed most heavily and is used by the lab for a variety of LOT-learning projects. GPL3
  
  
• pychuriso is a python implementation of churiso inference, which learns Church encodings from simple relational datasets. GPL3
  
  
• kelpy (kid experimental library in python) is a library for running simple psychology experiments in python. It is intended primarily for making simple animated displays with simple responses for baby and child experiments. It is built on top of pygame and supportrs Tobii eyetracking. GPL3

• data & code •

Data from all projects completed and in progress is available upon request

• One parameter is always enough Code for Piantadosi (2018)'s paper fitting an arbitrary scatter plot with a single free parameter. GPL3


• English Surprisal estimates -- data from Piantadosi, Tily, Gibson (2011), giving the average in-context surprisal of each word. Note that we now recommend use of ngrampy to compute this, using the free publicly available data from google books. Full data from the paper is available upon request.


• PyMC model and subject data -- from Piantadosi, Kidd, and Aslin (2014), implementing Bayesian, partially-pooled by-subject looking curves relating the surprisal of observed events to infants' probability of terminating attention.


• Open corpus of Pirahã A corpus of shallowly parsed Pirahã -- sentences used in Futrell et al.
  
  
• Set function logical learner data -- from Piantadosi, Tenenbaum, & Goodman 2016, Psych Review. Data on subject learning curves for 108 logical concepts.
