The lower brain, also known as the reptilian brain, is responsible for basic survival functions like breathing and heart rate. The higher brain, or neocortex, is involved in more complex functions like reasoning, problem-solving, and decision-making. The higher brain allows for advanced cognitive abilities and emotional processing, while the lower brain focuses on instinctual responses and automatic bodily functions.

Research has shown that there are persistent differences in IQ test scores across different racial and ethnic groups in the US, with some groups consistently scoring higher or lower on average than others. However, it is important to note that while there may be differences in average scores, individual differences within each group are greater than differences between groups.
The three functions of the mind, namely memory, attention, and executive functions, play a crucial role in deep learning and higher-order thinking. Memory helps retain and recall information, attention focuses on relevant stimuli, and executive functions enable planning, problem-solving, and decision-making. These functions work synergistically to facilitate complex cognitive tasks like critical thinking, creativity, and analytical reasoning in deep learning processes.
Research indicates that there are differences in emotional expression and regulation between sexes, with women often showing higher levels of both. These differences may be influenced by socialization, biological factors, and societal expectations. However, it is important to note that individuals vary widely within each sex, and these differences are not absolute.
Higher-order functions can be used to enhance brain function and cognitive abilities by allowing the brain to process information more efficiently and effectively. These functions involve complex thinking processes such as problem-solving, critical thinking, and decision-making, which can help improve memory, attention, and overall cognitive performance. By engaging in activities that require higher-order functions, individuals can stimulate their brains and improve their cognitive abilities over time.
The higher brain, which includes the prefrontal cortex, is responsible for complex decision-making involving reasoning, planning, and evaluating consequences. The lower brain, such as the amygdala, is more instinctual and reactive, influencing decisions based on emotions and survival instincts.
