Needles And Notions
psychology help please?
A health psychologist is conducting an experiment to investigate the notion that short-term psychological distress influences the immune system. Subjects in the first group watched a 30-minute film in which a carpenter and his assistant demonstrated how to build a deck for a house. Subjects in the second group watched an almost identical film, except that during last few minutes of the film, the carpenter slipped while operating an electric hand saw and cut off the fingers on his assistant’s hand. Immediately after the film, blood samples are drawn from each subject and assessed for the number of disease-fighting white blood cells. What is the dependent variable in this experiment?
a.The number of white blood cells found in the blood sample.
b.Exposure to the neutral film or to the film showing the accident.
c. The number of mistakes made by subjects in recalling details of the film.
d.Fear of needles and injections.
I understand the question. And have the answer. But I’m not going to do your homework for you.
