# Dataset Card for Aphantasic Drawing Dataset

<!-- Provide a quick summary of the dataset. -->

This dataset containts data from an online memory drawing experiment conducted with individuals with aphantasia and normal imagery.

## Dataset Details

### Dataset Description

<!-- Provide a longer summary of what this dataset is. -->
This dataset comes from the Brain Bridge Lab from the University of Chicago. 
It is from an online memory drawing experiment with 61 individuals with aphantasia 
and 52 individuals with normal imagery. In the experiment participants 1) studied 3 
separate scene photographs presented one after the other, 2)  then drew them from memory, 3) 
completed a recognition task, 4) copied the images while viewing them, 5) filled out a VVIQ 
and OSIQ questionnaire and also demographics questions. The scenes the participants were asked
to draw were of a kitchen, bedroom, and living room. The control (normal imagerty) and 
treatment group (aphantasia) were determined by VVIQ scores. Those with a score >=40 were control
and those with scores <=25 were in the aphantasia group. For more info on the experiment and design
follow the paper linked below.
The original repository for the data from the experiment 
was made available on the OSF website linked below. 
It was created July 31, 2020 and last updated September 27, 2023.

## Dataset Creation

### Curation Rationale

<!-- Motivation for the creation of this dataset. -->

[More Information Needed]

### Source Data

<!-- This section describes the source data (e.g. news text and headlines, social media posts, translated sentences, ...). -->
The orignal repository for the data included a folder for the participant's drawings (1 for aphantasia and 1 for control),
a folder of the scene images they had to draw (stimuli), and a excel file with the demographic survey and test
score data.
The excel file had 117 rows and the 2 folders for aphantasia and control had 115 subject folders total.
Subject 168 did not file out the demographic information or take the VVIQ and OSIQ test and 
subjects 160, 161, and 162 did not have any drawings. These 4 were removed during the data
cleaning process and the final JSON has 114 participants.

#### Data Collection and Processing

<!-- This section describes the data collection and processing process such as data selection criteria, filtering and normalization methods, tools and libraries used, etc. -->

The original excel file did not have total score for the VVIQ and OSIQ tests, but instead
individual points for each questions. The total score was calculated from these numbers.
The orignal drawing folders for each participant had typically 18 files. There were 6 files
of interest: The 3 drawings from the memory part of the experiment, and the 3 drawings from
the perception part of the experiment. They had file names that were easy to distinguish:
For memory: sub{subid}-mem{1,2,or 3}-{room} where the room was either livingroom, bedroom, or kitchen
and 1,2, or 3 depending on the order in which the participant did the drawings
For perception: sub{subid}-pic{1,2,or 3}-{room}
These files were matched with the excel file rows by subject ID,
so each participant typically had 6 drawings total (some participants
did not label what they were drawing and the file name was not in the normal 
format and therefore did not have all their drawings).
The actual image folder had 3 images (kitchen, living room, bedroom) that 
were replicated to go with each of the 114 participants.
The final format of the data is linked above.
