We study the effects of various elements of supervisory communication - peer performance information, encouragement, and praise - on the effort and performance of individuals. To do so, we randomize the provision of such communication elements during a simple online game of visual perception. The game will be advertised as a challenging game of self-improvement using social media outlets. We study the effect on various outcomes: intensity of play and number of games played (effort), as well as accuracy and game score (performance). We study the mean effect on players, as well as the effect on subgroups based on task-related confidence and gender.

Experimental Details
The intervention will include elements of performance feedback (own best score, leader board) and subjective feedback (encouragement, praise), given prior to and during the online game.

Primary Outcomes
Primary Outcomes (end points)
We plan to measure individual effort (number of games played, intensity of game playing (clicks)), as well as performance measures (accuracy of clicks, game score).

Experimental Design
Experimental Design
We will collect data using an online game that will be advertised using social media outlets.
During the 2 minute game, treatment will be given using pop-up text boxes using simple phrases and graphics.
Treatment will be randomized among the interactions of two dimensions: (1) performance information and (2) subjective feedback.
Experimental Design Details
Not available
Randomization Method
Randomization via computer (algorithm).
Randomization Unit
Randomization will be done at the individual game session level.
