Overview

This webpage archives resources and information associated with research done by Westley Weimer and colleagues relating to computer science and medical imaging.

Resources

We firmly believe in reproducible research and want to make our raw materials and de-identified data available to other researchers. We are quite interested in collaborations with other researchers, as well as having other researchers use our data for new analyses or baselines.

  1. Distilling Neural Representations of Data Structure Manipulation using fMRI and fNIRS (ICSE 2019)
  2. Decoding the representation of code in the brain: An fMRI study of code review and expertise (ICSE 2017)

Resources — "data structures and spatial ability"

We make available resources related to an fMRI and fNIRS study involving data structures, spatial ability, and problem difficulty. The study was conducted in 2018 at the University of Michigan and published in 2019. The published paper, which received a Distinguished Paper Award, is available:

IRB Protocols and Recruitment Materials

IRBs have different structures and requirements at different institutions. However, because health-related IRBs are typically more involved than non-health IRBs, other researchers may benefit from seeing how we phrased some of our responses.

For this paper we have two protocols: one for fNIRS (specific to data structures and spatial ability), and one for fMRI (more general for computer science tasks).

Training Videos

These training videos were shown to participants after pre-screening but before they entered the scanner.

Visual Stimuli

The exact data structure and mental rotation questions we presented to participants are available.

Resources — "code review and expertise" 2017

We make available resources related to a fMRI study involving expertise, code review, code comprehension and prose review. The study was conducted in 2016 at the University of Virginia and published in 2017. The published paper, which received a Distinguished Paper Award, is available:

IRB Protocol

IRBs have different structures and requirements at different institutions. However, because health-related IRBs are typically more involved than non-health IRBs, other researchers may benefit from seeing how we phrased some of our responses.

Recruitment Materials

These brief slides and tear-off handouts were used in classes and on bulletin boards to recruit participants. We followed up via email with interestd participants.

Pre-Screening Form and Correspondence

Our pre-screening form checks for relevant medical, software engineering and prose background. We followed up via email with students depending on whether they were medically a good fit for the study or not.

Training Video

This training video was shown to participants after pre-screening but before they entered the scanner.

Supervising Experimenter Notes

These notes remind researchers (e.g., professors, graduate students) about what to say to each participant and how to record the data. Some details are UVA-specific.

Visual Stimuli

The exact code and prose snippets and questions we presented to participants are available.

Experiment Scripts

These experiment scripts govern the presentation of visual stimuli and the collection of data at our local fMRI.

De-Identified fMRI and fNIRS Scans

We are significantly interested in other researchers making use of the de-identified fMRI and fNRSI scan data gathered at our institution. For example, other researchers might carry out different analyses on the same data or use this data as a baseline in subsequent experiments.

Brain scan data is covered by the Health Insurance Portability and Accountability Act (HIPAA).
