Is there any way to read someone's mind? Well, the chapter on human personality in your book talks about the fairly new field of personality neuroscience, and fMRI. It's an acronym for Functional Magnetic Resonance Imaging.

So, today, I want to talk about the application of fMRls for studying personality. fMRls produce pictures ... images of the brain while it's processing in Grmation or stimuli. I guess you are familiar with MRI which is a medical imaging technique used for diagnostic purposes. (However), fMRls are mainly used in the research world. Um ... standard medical MRls only visualize internal brain structures, (but) fMRls show what's actually happening inside the brain. In other words, how the brain is functioning at a given time. That tmakes fMRls a more useful research tool than medical MRls.

As for how fMRls work, well, basically, they use magnetic fields to measure brain activity in different parts by detecting asso iatedl changes in blood flow, and oxygen levels. So, in a sense, this information allows you to produce detailed pictures of the brain. A map with different parts of the brain, with different actions or emotions, or even thoughts.

And now, by using this teczhnology, psychologists have been seeking for answers for some questions about human personality. Personality is a set of psychological characteristics that remain stable over time. The questions were about, for example, the types of personality and the existence of itself. Yes?
