Stimulus Control

DOI

Stimulus Control is a fork of EAM (https://github.com/eep-lab/eam).

  • It is aimed at fast programming of behavioral experiments.
  • It can be extended to Design, Present, Record and Archive a wide range of behavioral experiments.
  • It was designed for Participants, Researchers and Developers.
  • It is a prototype to run non time-critical experiments.
  • It is being inspired by OpenSesame, Psychopy and Expyriment.

Some features

  • Text Messages

  • Simple Discriminations

  • Conditional Discriminations

  • Task Styles

    • Feature positive effect (uses keyboard as operandum)
    • Go/No-Go (using keyboard or mouse as operandum)
    • MTS (using keyboard or mouse as operandum)
    • SPAN (using keyboard or mouse as operandum, work in progress)
    • and others
  • Stimuli (antecedents, consequents):

    • Sounds using the (non-free, as in freedom) Bass library (a substitute is in need)
    • Images (jpg, bmp, png), opaque or transparent
    • Videos using the LCLVLC component and the libvlc library will be implemented.
  • Backgrounds

    • Random visual mask
    • Colors
  • Responses (schedules of reinforcements):

    • CRF, EXT
    • FT, VT
    • FR, VR
    • FI, VI,
    • DRH, DRL
  • Designs

    • Free operant
    • Discrete Trials
  • Performance Assessment/Criteria

    • Consecutive Hits
    • Hit porcentage in Bloc
  • Blocs of Trials

    • Create blocs of trials
    • Concatenate blocs of trials
    • Concatenate blocs of trials based on participant's performance (if criteria was reached, go to bloc x, if not go to bloc y)
  • Timestamped Events

    • Starts and endings of trials, Hits and Misses are timestamped by default
    • Custom timestamps can be implemented through custom trial types
    • For high precision and high granularity timestamps
      • We use EpikTimer package on windows
      • We use clock_get_time on linux
  • Pupil Communication (https://github.com/pupil-labs/pupil)

    • Auto start/stop of Pupil Recordings
    • Auto start/stop (and custom start) of the current selected Pupil Calibration Method
    • Prompts for unsuccesful calibration
    • More details about our implementation here: https://github.com/cpicanco/pupil-fpc
  • Cross-Platform. Tested under Windows (7, 8 and 10), Crunchbang 11, Ubuntu LTS (16.04) and Debian 9.

  • Free software, GPL3, compiled with Lazarus RAD IDE (1.8.2) and FPC (3.0.4).

  • Core code was written using a Behavior Analytic ontology.

Changes Made

  • Adapted from Delphi to Free Pascal compiler and Lazarus development environment
  • Replaced old GUI for a new prototype one
  • Fixed some timing bugs
  • Fixed some bugs related to the TTrial create/free life cycle
  • New trial types inherited from TTrial
  • Refactoring for better Behavior Analytic ontology fit.
