During experiment 1, how long were the photographs shown to participants?

200 milliseconds
500 milliseconds
1 second
2 seconds

The correct answer is: 500 milliseconds

The correct duration for which the photographs were shown to participants in Experiment 1 is 500 milliseconds. This specific time frame is significant in psychological research because it allows researchers to assess participants' quick cognitive processing and decision-making abilities. Showing images for shorter durations, like 200 milliseconds, would not provide sufficient time for participants to adequately perceive and recognize the content, while longer durations like 1 second or 2 seconds may lead to varied responses due to participants having more time to reflect or analyze the images. The use of 500 milliseconds strikes a balance, enabling effective study of immediate impressions or reactions without allowing for extensive contemplation.
