Emotion and Reason
This chapter studies the relationship between emotion and rational thought. Emotions have been found to be linked to chemical changes that can affect both mind and body. The brain is connected with the rest of the body through direct nerve connections to the organs, but also by brain regions like the hypothalamus, and glands linked to it such as the pituitary, that secrete hormones into the blood. As such, some scientists now argue that even human consciousness cannot be thought of as a product solely of the brain, but also of the body. A chemical that plays dual roles in the brain and the rest of the body is dopamine, which is vital for our control of movement and it also regulates many higher mental functions in humans, such as learning, concentration, planning ahead, and pleasure-seeking behaviour. The chapter then looks at the implications of Lev Vygotsky’s view of the interaction between rational thought and emotional responses for education. One important concept in this regard is what Vygotsky termed the 'zone of proximal development.
