Biological approach

• What does the biological approach emphasize in psychology?

  The importance of physical processes in the body.
• What are genes made up of?

  Chromosomes that consist of DNA.
• How do genes influence psychological features?

  They determine physical features inherited from parents.
• What is biological structure?

  An arrangement of parts to form an organ, system, or living organism.
• What does neurochemistry relate to?

  Chemicals in the brain that regulate physical functions.
• What is genotype?

  The particular set of genes that a person possesses.
• What is phenotype?

  The characteristics of an individual determined by both genes and the environment.
• What is evolution in biological terms?

  Changes in inherited characteristics in a biological population over successive generations.
• What is Phenylketonuria (PKU)?

  An inherited error of metabolism.
• What are some symptoms of Phenylketonuria (PKU)?

  Skin rash, convulsions, and a musty body odor.
• How can PKU be managed?

  By controlling diet and avoiding certain foods.
• What is the relationship between genotype and phenotype?

  Genotype leads to phenotype, but the environment can also influence phenotype.
• How can the environment affect phenotype?

  Environmental factors like diet can change the expression of genes.
• What is the impact of a specific diet on individuals with Phenylketonuria (PKU)?

  A specific diet can prevent the accumulation of harmful substances and improve phenotype.
• What happens if individuals with PKU do not follow their diet?

  It can lead to severe learning and behavioral problems.
• What is the significance of secure attachment in infants?

  It helps ensure that the infant receives care and support from the caregiver.
• How does natural selection relate to behavior?

  Natural selection favors behaviors that enhance survival and reproduction.
• What is the biological approach's view on mental illness?

  It assumes that mental illness is caused by biological factors, such as neurotransmitter imbalances.
• What are some methods used in the biological approach?

  Techniques like fMRI and EEG are used for accurate measurements of brain activity.
• What are the strengths of the biological approach?

  It uses precise scientific methods and has led to effective treatments for mental illnesses.
• What is a weakness of the biological approach?

  It may oversimplify complex behaviors by attributing them solely to biological factors.
• How does the biological approach view the nature vs. nurture debate?

  It struggles to separate the influences of nature (genes) and nurture (environment) on behavior.
• What is the implication of having a genetic predisposition for certain behaviors?

  It suggests that individuals may have a biological basis for certain behaviors, but environment also plays a role.
• What are the key components of the biological approach in psychology?

  • Emphasizes physical processes in the body
  • Focuses on genes and their influence on behavior
  • Studies neurochemistry and its effects on mental functions
  • Uses scientific methods for research and treatment
• What are the strengths and weaknesses of the biological approach?

  Strengths:

  • Precise scientific methods
  • Effective treatments for mental illnesses

  
  

  Weaknesses:

  • Oversimplifies complex behaviors
  • Struggles with nature vs. nurture debate
