Experiment 2: One Target in Many Situations

This study, called "Experiment 2: One Target in Many Situations," is looking at how people find things visually. Researchers want to see if there's a difference in how you search when you're looking for the same item many times in a row (called "Blocked Trials") compared to when you're looking for different items in a mixed-up order (called "Mixed trials"). The study will test four different search tasks where the item you're looking for stays the same, but the distracting items around it change. The main goal is to measure how quickly you respond (Response Time) to find the item. This study is for healthy adults aged 18 and older who can pass a color vision test and have good vision (20/25 or better with correction). We are looking for about 40 participants.
