This is a literature review paper. I need 7 sources minimum, i will provide all instructions attached. APA format, this is due by 11:59pm on sunday october 30th. We were to pick a topic that has been studied before. A topic that has a dependent and independent variable. I actually have 2 options and you can pick whichever is easier to find research on. 1st option for the topic: Does owning a pet (or even certain pets like specifically a dog or cat) decrease depression and/or does having one pet decrease depression more than the other (like does owning a dog decrease it more than a cat or vise versa). 2nd option: how does over or under sleeping (more or less than the recommended 8 hours of sleep) affect our health/daily life.
