Humanities Homework Help

I have been having a hard time finding three previous experiments/studies on the Halo effect for my research paper. I have already written the introduction paragraph, but what I need is three paragraphs on experiments conducted on the Halo Effect (that deals with a persons physical attractiveness) from credible sources. For each paragraph please explain who the experiment was conducted by, how the experiment was conducted, and important findings. Please include in text citations, as well as a works cited page. I will be using this as a reference to finish off my paper.
