Using Jupyter notebooks for interactive analyses and reproducible science


The Jupyter notebook is a widely used tool for performing reproducible, interactive data analysis. As a "digital lab notebook", Jupyter weaves together code, prose, images, and more, allowing users to iterate on analyses and view the results all within a single document. This tutorial will give a hands-on overview of some of the notebook's capabilities using Python, including how the notebook integrates with Python packages such as matplotlib, pandas, and statsmodels. Additionally, this tutorial will cover more advanced uses, including "widgets" for interactively exploring data, conversions to other formats such as HTML, using the notebook with R, and reproducibility.

Reproducible analysis of bigger, naturally-occurring datasets using R, Rmarkdown, and the tidyverse


The availability of data on the web has opened up many resources for cognitive scientists who know how to deal with "medium data" - big enough to crash excel but small enough to load into memory. R is a powerful tool for statistical data analysis and reproducible research, and the "tidverse" - an ecosystem of R packages for manipulating, analyzing, and visualizing data - provides many tools for manipulating this kind of data quickly and easily. In this tutorial, I'll walk through how to go from a database or tabular data file to an interactive plot with surprisingly little pain (and less code than you'd imagine). My focus will be on introducing a workflow that uses a wide variety of different tools and packages, including readr, dplyr, tidyr, and shiny. I'll assume basic familiarity with R and will use (but not spend too much time teaching) ggplot2.

Collecting data from the web


This workshop will explore different ways to collect data from the web with Python. Have you ever needed to copy and paste hundreds (or thousands!) of tables on different web pages? Or click through combinations of dropdown menu selections and download files? Are you interested in collecting social media or news data? After this workshop, you'll be well on your way to automating these processes. We will first consider getting data from RESTful APIs. We will walk through using the documentation to build a query for a GET request. We'll then write our response to a CSV spreadsheet. We'll then discuss web scraping, keeping in mind the Terms of Service for websites and ensuring we are not in violation. We will look at two ways of scraping: 1) parsing the HTML response of a GET request using BeautifulSoup, and 2) utilizing the Selenium web driver to interact directly with dynamic web content.

Statistical models for dependent data: An introduction to mixed models in R


R is an open source programming language for statistical modeling and computation. The first goal of this talk will be to give a general introduction to statistical modeling in R, specifically in the context of linear models. Most psychological data sets incorporate repeated measures (i.e., multiple observations from the same unit of observation) or multiple independent sources of random variation (i.e., crossed random effects). Unfortunately, ordinary linear models are not a suitable for such data as they assume independence of the data points conditional on the statistical model. The second goal of the talk is to introduce linear mixed models, a powerful model class that can handle all the aforementioned issues and is becoming more and more popular. This part of the talk will focus on R packages lme4 and afex.

Instructor: Henrik Singmann (University of Zurich, Switzerland)

Henrik is a postdoc at the University of Zurich in the lab of Klaus Oberauer and interested in cognitive and statistical models for psychology and related disciplines. He is author of a number of R packages such as afex, rtdists, and bridgesampling. Most of his substantive work is on aspects of higher-level cognition such as reasoning or memory. [website]

Social media analysis


People love to talk on the web. How can we listen to what they're telling us, and why would we want to? This workshop will discuss some methods of collecting social media data to construct larger---and in some cases, more naturalistic---datasets than laboratory-based experiments yield. We'll cover methods for building datasets through Python-accessible Twitter APIs, and structuring both the search query and the experimental question to obtain data that is appropriate in both content and amount. We'll also discuss connections between data and metadata, with a focus on geolocation, as well as ways to collect online conversations and interactions.

Instructor: Gabriel Doyle (Stanford University)

Gabe Doyle is a postdoc in Psychology at Stanford, and a soon-to-be Assistant Professor in Linguistics and Digital Humanities at San Diego State. He's interested in better understanding the psycholinguistics, sociolinguistics, and pragmatics of conversation. To figure that out, he combines computational models of communication with emerging big data sources, like Twitter and e-mail databases.  Some cool results of this work include showing that Twitter can be used to map American dialectal syntax, that the amount of information provided in a tweet trades off with how exciting and unexpected of an event it discusses, and that employees who eventually stay at or leave a company use “we” differently in their work emails.

Working with heterogeneous datasets: a real-world example


The analysis of real-world data often involves acquiring, cleaning, and merging heterogeneous datasets from disparate sources. Often times, our behavioral questions require combining datasets that are in different formats, timescales, geographic levels of granularity, and even different dimensionality (e.g., spatial versus temporal data). Using a series of worked examples from my ongoing research examining the risk-taking behavior of New York City residents, this tutorial outlines common challenges and approaches for dealing with these heterogeneous datasets, as well as explores some public data sources which are can be critically useful for elucidating real-world behavioral questions. This tutorial will assume some familiarity with Python, ‘pandas’ data structures, and basic web queries.

Instructor: Ross Otto (McGill University)

Ross Otto is an Assistant Professor of Psychology at McGill University. He obtained his BS in Cognitive Science in 2005 from UCLA, and his PhD in Psychology from UT Austin in 2012. He completed postdoctoral work at NYU’s Center for Neural Science prior to beginning his position at McGill. Otto’s work relies on a combination of computational, behavioral, and psychophysiological, and (more recently) “big data” techniques to understand how people make decisions both in the laboratory and in the real world.

Efficiently analyzing large-scale n-gram text data in R


Massive natural language datasets are now widely available for public use. Given the size of these datasets, even the simplest language models, such as n-gram analyses, require considerable computational power. The necessary computational requirements impose soft limits—available only to those trained in computational efficiency—to these rich datasets even though they are free to use. To help bridge computational efficiency with behavioral research agendas, my colleagues and I developed the R package, cmscu, a replacement to the standard DocumentTermMatrix function in R’s tm package. I will show how cmscu can be used to implement some of the most sophisticated n-gram algorithms.

Instructor: David W. Vinson (University of California, Merced)

Algorithmic experimentation with Dallinger


As experimentation in the behavioral and social sciences moves from brick-and-mortar laboratories to the web, new opportunities arise in the design of experiments. By taking advantage of the new medium, experimenters can write complex computationally mediated adaptive procedures for gathering data: algorithms. This tutorial introduces participants to Dallinger, a software platform for algorithmic experimentation that uses crowdsourcing to automate the full pipeline of experimentation, from participant recruitment through data handling. Participants will get hands-on experience with the platform through examples of psychological methods such as the transmission chain and minimal group paradigm. The session will include discussion of machine learning techniques, such as active learning, that can be applied to psychological experimentation through Dallinger.
