The question mentions that each photo is presented for about one-quarter of a second, and the observers can detect the change in the photos after about alternation cycles. Therefore, the number of cycles required for detection is dependent on the duration of the presentation of each photo. The answer choices offer different numbers that could represent the duration of each presentation. A duration of 2 cycles would mean each photo is presented for 0.5 seconds (the time for two cycles), which is too long for change blindness experiments. A duration of 100 cycles would mean each photo is presented for 25 seconds (the time for 100 cycles), which is also too long for these experiments. Therefore, the best choice is B, 12 cycles, which means each photo is presented for 3 seconds (the time for 12 cycles), which is a reasonable duration for change blindness experiments.
