Basics of Scientific Method

Lecture notes

Research hourglassWe continue with basic assumptions of the scientific method, addressing the "hourglass" model of the overall research flow. We will define each of these terms: these will be central to the course (and the midterm!). These are in Week 2 lecture notes

Some Key terms (yes, these will be on the exam...):

Readings

Recommended Text: What is Science and Introduction to Methods of Science from Ray or whatever text you are using.


Discussion group Assignment

Neurolaw imageBrain science and legal / moral responsibility
Religious or ethical systems assume people are responsible for their decisions and behavior: people exercise "free will" when they commit a crime.  What if brain science tells us we are basically machines, without free will in the usual sense?

Functional magnetic resonance imaging (fMRI) allows scientists to actually watch the brain while it is working. What if these data show that some people commit crimes due to a “brain problem” – a tumor, or restricted blood flow -- that interferes with their "free" decision making?   A new sub-discipline called “Neurolaw” addresses the legal implications of brain research. 

Click the image above for an article on “Neurolaw”, and click on the image in the bonus section for a NPR audio report. Then, write a sentence or two on each of the following:
