# Stimulus Control

[![DOI](https://zenodo.org/badge/17609066.svg)](https://zenodo.org/badge/latestdoi/17609066)

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.
