The Biological Approach

Extracts from this document...


The Biological Approach One of the most confusing issues in psychology is that of understanding the relationship between the mind and the brain. Biological psychology is the scientific study of the biological bases of behavior and mental states. Because all behavior is controlled by the central nervous system, it is sensible to study how the brain functions in order to understand behavior. The biological approach looks at psychology from a psychological perspective, that is, it considers physical changes in the body. It investigates how chemical and electrical events that occur within us affect our thinking, emotions and behaviour. The main assumptions are of the approach are based on biology and include the following ideas: the structure and function of neurones and the structure and function of the brain. Psychologists understand these ideas, and therefore can use this understanding to develop therapies to help people to overcome mental health problems. The two most commonly known therapies are the psychosurgery which operates on the brain to control mental disorders and the other - chemotherapy, which uses drugs to control mental disorders. ...read more.


A surface view of the brain shows it is divided into 'lobes'. 1.The frontal lobe, found in the area around your forehead is concerned with emotions, reasoning, planning, movement, and parts of speech. It is also involved in purposeful acts such as creativity, judgment, problem solving, and planning. 2. The Parietal are found behind the frontal lobes, above the temporal lobes, and at the top back of the brain. They are connected with the processing of nerve impulses related to the senses, such as touch, pain, taste, pressure, and temperature. They also have language functions. 3. The temporal lobes are found on either side of the brain and just above the ears. They are responsible for hearing, memory, meaning, and language. They also play a role in emotion and learning. The temporal lobes are concerned with interpreting and processing auditory stimuli. 4. The occipital lobe is found in the back of the brain. It is involved with the brain's ability to recognize objects and responsible for our vision. ...read more.


If the stress is not severe or long-lasting, we bounce back and recover rapidly. Stage 2: Resistance: Eventually, sometimes rather quickly, we adapt to stress, and there's actually a tendency to become more resistant to illness and disease. Our immune system works overtime for us during this period, trying to keep up with the demands placed upon it. We become complacent about our situation and assume that we can resist the effects of stress indefinitely. In that lays the danger. Believing that we are immune from the effects of stress, we typically fail to do anything about it. Stage 3: Exhaustion: Because our body is not able to maintain homeostasis and the long-term resistance needed to combat stress, we invariably develop a sudden drop in our resistance level. No one experiences exactly the same resistance and tolerance to stress, but everyone's immunity at some point collapses following prolonged stress reactions. Life sustaining mechanisms slow down and sputter, organ systems begin to break down, and stress-fighting reserves finally succumb to what Selye called "diseases of adaptation." ...read more.
