shortvideos

Purpose

The goal of the short videos task is to produce data capable of training a sensitive and specific neural signature of self-reference.

Paradigm

In this task, participants complete 21 blocks of 3 trials.

In each block, they are asked to make one type of judgement for three different videos in a row.

To make ratings, participants are shown a semi-circular rating scale with a prompt to make a specific rating. A red dot begins equidistant from all points on the scale.

Participants then use a trackball in the scanner to move the red dot to the appropriate area on the scale that matches their rating. They then click a button to submit their response.

Videos are all approximately 5 seconds long. After each video participants give a rating on a semi-circular scale ranging from 'not at all' to 'most imaginable'. The three classes of ratings they make are:

1. Self-similarity (i.e. "how similar are you to this character")
2. Likeability (i.e. "how much do you like this character?")
3. Mentalizing (e.g. "how much was this character afraid of heights?")
   • Note two unique characteristics of the mentalizing question:
     • The rating scale will not measure how 'much' mentalizing the participant was doing
     • There are 7 different mentalizing questions because no single mentalizing question related directly to every video. The different questions insure that there is more variance in mentalizing across videos.

##To Dos

1. Swap out screenshots above to newest version ('how similar are YOU to this character')

Below is one example screenshot of each of the 3 possible rating scales:

1. Self-similarity
2. Likeability
3. Mentalizing
