3) What kind of experiment was it?

1) There were 2 conditions. One involved a weapon the other did not. Participants in both conditions heard a heated discussion from the next room. In condition 1, a man emerged holding a pen with ink on his hands. In condition 2, a man appeared holding a paper knife covered in blood. They were all asked to identify the man from 50 photos.

2) Participants in condition 1 were 49% accurate. Those in condition 2 were 33% accurate.

2) This was a field experiment because the researcher had controlled some of the variables and planned the experiment but the participants did not know that they were being studied on.
