-Neurons adapt to detect movement and stimuli -When you look at or feel something for so long, you start to become immune to that stimuli and start looking for new ones (bloody Mary explained)
Know the major functions of important sections of the brain:
-Parietal Lobe: 3D space orientation of body, integrates sensory information -Prefrontal Cortex (PC): deciding opposites -Anterior Cingulate Cortex (ACC): Determines "correctness" -Brainstem: autonomic function -Cerebellum: balance, body coordination -Diencephalon: -Homeostasis, melatonin

Galileo
What evolutionary benefits does patternicity give to a species
Helps us to develop pattern that help us to survive by learning what works/is true and what doesn't work/is false.
What is locus of control and how does it relate to patternicity
How much control of the environment we feel we have, relates to patternicity bcwe adapt and try to change our environment to fulfil forms of paternity. Ex: We developed the sweettooth when sweets were rare but now we changed the environment and they are no longer rare.

How was patternicity expressed in humans during Kiochi Ono's experiments?
Points delivered on variable schedule to human in box with levers-Humans developed superstitions for "gaining"points-Superstition took longer to develop than pigeons, but was harder to break
What is the most important question? Why? Haha, see what I did there? Yeah, that's some witty humor right there.
Question of WHY is most important because it is the basis for understanding, without why the beliefs are arbitrary
Scientific Method Steps
Question, Research, Hypothesis, Experiment, Analyze the Data, Conclusion
Only reliable method humanity has to find true answers to how universe works
