Outline and Evaluate the Biological Approach in Psychology

The biological approach in psychology is a fundamental perspective that assumes all psychological phenomena have biological origins. This approach investigates how biological structures and processes within the body impact our behavior, emphasizing the role of genetic and environmental factors in shaping human conduct.

Genetic Influences and Mental Illness

The biological approach posits that mental illnesses can be transmitted through genetic material. This is studied by examining concordance rates among biological relatives. For instance, monozygotic twins have a 48% likelihood of developing Schizophrenia if one twin has already been diagnosed Janick2001Janick 2001. This highlights the genetic and environmental influences on behavior in psychology.

Example: McGuffin et al. 19961996 studied twins where one already suffered from depression. They found a 46% concordance rate for depression in monozygotic MZMZ twins and a 20% rate in dizygotic DZDZ twins, suggesting a genetic component to depression.

Evolutionary Psychology and Behavior

Evolutionary psychology, a subset of the biological approach, considers genetic influences on common behaviors. It explains that genetically determined behavior results from sexual selection, enhancing survival chances.

Example: Attachment behavior is considered an evolutionarily advantageous trait that increases offspring survival.

Brain, Nervous System, and Neurotransmitters

The biological approach emphasizes studying the brain, nervous system, and other biological systems such as hormones and neurotransmitters.

Highlight: Dopamine is thought to play a role in Schizophrenia Comer2003Comer 2003, while serotonin levels can impact depressive disorders.

Strengths of the Biological Approach

  1. Scientific Validity: The approach utilizes scientific techniques, such as brain scanning fMRIfMRI, to produce objective and reliable data, increasing internal validity.
  2. Treatment Development: It has enabled the development of effective drug treatments for mental illnesses, such as SSRIs for depression.

Criticisms and Limitations

  1. Reductionism: The approach may oversimplify complex psychological phenomena by reducing them to purely biological factors.
  2. Determinism: It assumes that human behavior is primarily controlled by internal genetic causes, leaving little room for free will or choice.
  3. Incomplete Explanation: While genetic factors are important, they don't fully explain all aspects of human behavior and mental illness, as evidenced by the less than 100% concordance rates in twin studies.

Vocabulary: Diathesis-stress model: A theory suggesting that individuals may be genetically predisposed to certain behaviors or illnesses, but environmental triggers are necessary for their development.

In conclusion, while the biological approach in psychology provides valuable insights into the physiological bases of behavior and mental processes, it should be considered alongside other psychological perspectives for a more comprehensive understanding of human behavior.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

Just amazing. Let's me revise 10x better, this app is a quick 10/10. I highly recommend it to anyone. I can watch and search for notes. I can save them in the subject folder. I can revise it any time when I come back. If you haven't tried this app, you're really missing out.

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.
