(03.01 MC)In a recent study, 100 college students were shown pairs of images with subtle differences and asked to identify changes between them. The study aimed to measure the accuracy and speed of change detection under different conditions, focusing on the complexity of the scenes and the size of the changes. Condition Scene complexity Size of change Mean accuracy (%) Mean Response Time (seconds) Change detection (simple) Low Large 90 360 Change detection (difficult) High Small 55 750 What are the dependent variables in this study?

(02.03 MC)Scientists are studying the effectiveness of a new antidepressant. Ten rats are given a standard dose of a currently available medication. Another group of 10 rats are given an equivalent dose of a new medication. MRIs that show brain activity through color are used to measure the absorption of the medications. Low brain activity is indicated by grays and blues. Normal brain activity is indicated by greens and yellows. High brain activity is indicated by reds and oranges. All the rat’s brains showed reduced activity prior to being exposed to their respective medication.What type of study was conducted by the scientists?

(03.04 MC)A teacher is investigating memory using her students as subjects. She gives her students a chronological list of U.S. presidents through 2008. Students were given a week to memorize as many names as they could in order. They were asked to record whether or not they studied each day (YES or NO). On the last day of the study, the teacher quizzed her first and last classes of the day. She noted that students in her last class performed better than students in her first class. Which of the following is the dependent variable?
