Studies of Human Inference Using On-line Testing

This study is looking at how people make decisions. You would participate in an online test called "psychophysics" where you'll see two locations and "package drops" that switch between them. Your task is to figure out which location is currently active and predict the next one. Researchers will record your responses and how quickly you answer. To join, you need to be an adult (18 or older) living in the US, speak fluent English, and have a 95% approval rating on the Prolific platform, plus pass a pre-test with at least 80%. The study aims to understand the decision strategies people use in short-term, long-term, and multi-timescale tasks. The study plans to enroll 500 participants.

Study design
This is an interventional study involving 500 participants. It is not specified if the study is randomized or blinded.
What's involved
You would complete a decision-making task online, which involves identifying current and predicting next locations based on package drops. This task will take approximately 30 minutes, with responses measured 1-5 times per minute.
Compensation
Not stated in the trial record.
Follow-up
Your behavioral responses will be measured through task completion on each trial, which takes approximately 30 minutes.
