Game of Thrones - A naturalistic viewing dataset

# Game of Thrones - A naturalistic viewing dataset

## Overview
This dataset contains fMRI movie-watching and category localiser data in 28
developmental prosopagnosics and 45 neurologically healthy controls.
Participants are additionally grouped by their familiarity with the Game of
Thrones television series.

In movie-watching scans, participants passively viewed a series of short
audiovisual clips (ranging from 50 to 117 s duration; total duration =
12 min 58 s) taken from the Game of Thrones television series.

In category localiser scans, participants viewed images of faces, scenes, and
phase scrambled versions of the face images. These can be used to define face
and scene selective regions of interest.

## Data Contents
* `participants.tsv` - List of subject IDs in control and developmental
prosopagnosic groups, along with whether they were familiar or unfamiliar
with Game of Thrones.

* `slice_timings.tsv`, `fsl_slice_timings.txt` - Slice timings for functional
scans. The TSV file gives the times in milliseconds, and the text file gives
the times in normalised units of the TR suitable for entering into FEAT.

> Scans were acquired with the HCP/CMRR multiband sequence. More information
> on slices timings can be found at:
> https://wiki.humanconnectome.org/download/attachments/40534057/CMRR_MB_Slice_Order.pdf

* `behavioural_measures.tsv` - Scores on PI20, CFMT, and Game of Thrones quiz
tasks (see below for more details). PI20 scores are out of 100. CFMT scores
are given as percentage accuracies. Quiz scores are given as percentage
accuracies over all questions as well as broken down by face, scene, and
narrative questions.

* `Subject Directories` - MRI data directories for each subject:
- `anat` - T1 anatomical images
- `fmap` - Magnitude and phase difference fieldmap images
- `func` - Movie-watching (Game of Thrones) and category localiser data

## Behavioural Measures
We provide two measures of face processing ability (PI20 and CFMT) and a quiz
assessing familiarity with the Game of Thrones TV series. All participants
completed the Game of Thrones quiz, and all developmental prosopagnosics
completed the PI20 and CFMT assessments. Approximately half of the control
subjects also completed the CFMT.

* `PI20` - 20-item prosopagnosia index, used as initial screening for
developmental prosopagnosia. All developmental prosopagnosic participants
comleted this.

* `CFMT` - Cambridge Face Memory Test, used as secondary screening for
developmental prosopagnosia. All developmentral prosopagnosic participants
and approximately half of the control participants completed this.

> Reference: Duchaine & Nakayama (2006), Neuropsychologia, 44(4), 576-585.

* `Game of Thrones Quiz` - We developed this quiz to assess familiarity with
the Game of Thrones television series. All participants completed this quiz.
The quiz comprised 3 types of questions:
* **Face** questions presented participants with a picture of a character,
and participants had to provide a name or some defining biographical
information for that character (e.g., "Jon Snow").
* **Scene** questions similarly presented participants with a picture of a
scene from the show and participants had to name or provide some details of
the location (e.g, "King's Landing").
* **Narrative** questions were 4-option multiple choice questions about key
elements of the Game of Thrones story. For example, "Which character was
Lord of Winterfell and was beheaded at the end of Season 1 - A) Daenerys
Targaryen, B) Jon Snow, C) Ned Stark, or D) Tyrion Lannister?"

## Notes
* sub-DP15 is missing category localiser and fieldmap scans due to time
constraints during the scanning session.
