Experiment Details
==================

Recall that the experiment protocol is located on Dropbox at:
``DJW_Projects/02_FOOD_REG/PAPERWORK/fMRI_Food_Regulation_Experiment_Protocol.gdoc``


---------
Main Task
---------

----------
Localizers
----------

--------------
Questionnaires
--------------


All versions of the project were created in `Psychopy`_.
The code for all `experiment versions`_ is on github.

.. note::
The main task involved three discreet phases.

Versions 1 and 2 were made with the Builder interface.
Version 3 was written in plain Python using the Psychopy 3 toolbox.
1. Pre-Scan

.. _experiment versions: https://github.com/danieljwilson/MADE/tree/master/3_experiment/3_1_inputs/versions
.. _Psychopy: https://www.psychopy.org/

====

The current iterations of the project include:
- Food liking ratings
- Main task training

---
v1
---
2. Scan

Description
-----------
- 1,2,3 multipliers
- In-scanner trials

Goal
-----
- Disambuguate atribute weights from attribute evaluation
- Test whether value and weighting affect subject attention
- 9 runs

---
v2
---
3. Post-Scan

Description
-----------
- Additional multipliers (0.1, 0.5, 1, 2, 3, 10)
- Food liking ratings (repeated)
- Food taste ratings
- Food health ratings

Goal
-----
- Test response to fractional weights
- Calculate subjects' weighting curve to wider range of weights
=====

------
v3.0.1
------
The code for the Main Task (including the instructions)
was written in ``MATLAB`` and uses `Psychtoolbox`_.

Description
-----------
- Both multipliers onscreen simultaneously (0.1, 0.33, 0.5, 1, 2, 3, 10)
The `Main Task Code`_ includes many files, but the key scripts are:

Goal
-----
- Test whether subjects bias their first/total
fixation to the higher multiplier
- ``runPreMRI.m``

------
v3.0.2
------
- Launches the experiment instructions and the initial Food Liking Rating

Description
-----------
- Accuracy incentive
- Both multipliers onscreen simultaneously (0.1, 0.33, 0.5, 1, 2, 3, 10)
- ``runSession.m``

- Launches a run of the experiment in-scanner

Goal
-----
- Test whether subjects try harder with an accuracy incentive,
rather than a cumulative payoff
- ``runPostMRI.m``

* This avoids the most difficult trials having the lowest value/cost
- Launches the post task ratings of Liking, Taste, and Health

------
v3.1.0
------

Description
-----------

- Time pressure (low)
- Accuracy incentive
- Both multipliers onscreen simultaneously (0.1, 0.33, 0.5, 1, 2, 3, 10)
.. _Psychtoolbox: http://psychtoolbox.org/
.. _Main Task Code: https://github.com/danieljwilson/cogReg_fMRI/tree/master/3_experiment/3_1_inputs/main_matlab

----------
Localizers
----------

Goal
-----
- Test whether time pressure increases the likelihood of biasing
first fixation toward the higher weighted stimulus
The localizer task invovled two descreet phases.

------
v3.1.1
------
1. Pre-Scan

Description
-----------
- Localizer task training

- Time pressure (low/high/no)
- Accuracy incentive
- Both multipliers onscreen simultaneously (0.1, 0.5, 1, 2, 3, 10)
2. Scan

Goal
-----
- Test whether time pressure increases the likelihood of biasing
first fixation toward the higher weighted stimulus under three conditions.
- In-scanner trials

------
v3.2.0
------
- go-nogo: 2 runs
- switching task: 1 run

Description
-----------
The code for the Localizers was written in ``Python``,
using the `Psychopy`_ toolbox.

- Full choice (multipliers and images)
- Accuracy incentive
- (0.1, 0.5, 1, 2, 3, 10)
There are two key scrtips CONTINUE FROM HERE

Goal
-----
- Test whether a stimulus (base value) or multiplier (weight)
bias exists.

------
v3.3.0
------
--------------
Questionnaires
--------------

Description
-----------
Upon completion of all tasks we asked subjects to
complete the following questionnaires:

- Bias test: Attractiveness
- Accuracy incentive
- (0.1, 0.5, 1, 2, 3, 10)
1. CONTINUE FROM HERE

Goal
-----
- Test whether subjects over-weight attractive vs. unattractive
faces

Running the Experiment
----------------------


The experiment runs using Psychopy 3.1.

The experiment protocol can be found on Dropbox at
``DJW_Projects/01_MADE/PAPERWORK/MADE_v3_Protocol.gdoc``
``DJW_Projects/02_FOOD_REG/PAPERWORK/fMRI_Food_Regulation_Experiment_Protocol.gdoc``

The protocol includes information regarding:

The questionnaire is hosted on Qualtrix.

- Recruiting Participants
- Running Study

The study questionnaire is a Google Form, and lives on the lab's
Google Drive account.
