Abstract
Our minds wander frequently. This project overall aims to answer basic economic questions about this process. This registration is only for preliminary data collection in the first two baseline treatments. A second registration will be linked to this (or this will be appended).

Primary Outcomes

Primary Outcomes (end points)
Our main measure of mind-wandering is the total number of mistakes made in the “main task” portion of the study. Mistakes are the sum of incorrect answers and answers not provided in the allotted time.
We will look at how this varies with respect to the intervention, how it varies over time, whether incorrect answers or late answers are more prevalent, how common mistakes are versus the use of a pause button, as well as correlates with survey measures.

Experimental Design

Experimental Design
The experiment measures whether a subject is on task using a sustained attention to response task: Words flash on the screen one-at-a-time, and every so often, the sequence stops. At this point, the participant is required to recall what the most recent word that was shown, choosing from four options. Every time they provide an incorrect answer or the answer is too late, they have to do additional tasks to earn their payment.

Note this is being done online, through Prolific.
Experimental Design Details
Randomization Method
Randomization is done within the Qualtrics survey, according to prescribed ratios.
Randomization Unit
Randomization is done at the individual level.
Was the treatment clustered?
No

Sample size (or number of clusters) by treatment arms
150 in each arm, stratifying on gender
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
Though we are randomizing an intervention, this data collection is only preliminary. These data will be used to (i) provide stylized facts about mind-wandering, (ii) calibrate power calculations for other treatments, and (iii) be pooled with future data in these cells for analysis of the treatment effect of varying the size of the extrinsic penalty of providing incorrect or late answers.
