The most interresting aspect of this course that I enjoyed learning more about was the information in Chapter 5 which was Homeostatsis.
Homeostatsis is to maintain constant internal body conditions. Constant Condition examples: Food=eatting or if a person is cold and they up their body temp they are now in a pleasent state.
Homeostatsis also has a negative feedback system. This explained how self-correction processes reduce discrepency.
Effects of deviation & Set points create physiological needs.
Examples of physiological needs, or drives are food and water.
Another example is alliesthesia which can catorgorize our needs useing set points and whether they are pleasent or unpleasent based on a specific need.
As humans we seek pleasent things to maintain homestatsis.
