The chapter that I think I will find the most interesting in the textbook is chapter three because it imports the biological aspect of psychology. To some, psychology seems to be mostly a mental science that deals strictly with how the human mind thinks as opposed to an actual biological science.I find the biological part of psychology the most appealing because it gives the mechanics behind all of the complex thoughts and emotions that humans experience. Chapter three goes over a lot about the brain, hormones, and neurons.This is interesting because it even includes studies about the right and left hemisphere of the brain. Chapter three makes clear that no human mind uses the same kinds of brain function, but all brains function in the same way. I also think that electrical and chemical impulsing is very neat. The fact that there are billions of neurons in the human body really puts into perspective of how many mechanisms go into simple thought processes.
