subjects in experiments. The use of human beings for experiments or research can have lasting negative effects on that individual such as emotional and psychological damage. The Milgram experiment even though it was a hoax had a lasting effects on many of it’s participants in both positive and negative ways and is a example of why humans should not be used as test subjects. The Milgram experiment was conducted by Stanley Milgram a assistant professor of psychology at Yale. The experiment wanted to

The graph should show an increase in arbitrary units the further away from the light source the beaker is because the greater the distance from the light source‚ the lower the light intensity and so less photosynthesis

- Quasi Experimental Design: If the researcher lacks control over the assignment of participants to conditions and does not manipulate the causal variable of interest‚ the design is quasi experimental. o Quasi Experiments do not have internal validity because participants are not randomly assigned to conditions and the researcher may have no control over the independent variable. - Basic Confounds in Quasi Experimental Design are : o History o Maturation (Emotional‚ Physical & Psychological)
