Dockerfile-experiment

# builds an image for running the memory-dynamics experiment
# Use Dockerfile-analyses to build an environment for reproducing the analyses.
#
# Note: the latest release of psiTurk (v3.3.1, October 2022) requires Python
# 3.9, which is EOL and no longer officially supported.
# experiment-requirements.txt pins all of psiTurk's dependencies to compatible
# versions to ensure the experiment still runs.
