Biological approach

• What is the ultimate cause of behavior according to the text?

  Biological cause
• How should psychology be viewed according to the text?

  As a science
• What determines our behavior according to the text?

  Genetics and physiology
• What does behavior being inherited imply?

  It is determined by genetic information
• What is a genotype?

  The genetic code for a trait
• What is a phenotype?

  The observable characteristics of an individual
• What is the purpose of looking for the concordance rate between twins?

  To see if MZ twins have higher concordance
• What do identical twins share?

  The exact same genetic make-up
• What do non-identical twins share?

  50% of genetic material
• What is evolution?

  The development of organisms over time
• How is evolution described in the text?

  As a biological approach
• What are the strengths of the biological approach in psychology?

  • Uses scientific methods
  • Employs experiments
  • Findings are replicable and reliable
• What is a key feature of the experiments used in the biological approach?

  They are objective and highly controlled
• What does the biological approach suggest about free will?

  We have no control over our genetics
• How can the biological approach be characterized?

  As deterministic
• What is a criticism of the biological approach?

  It can be seen as too simplistic
• What is the definition of genotype?

  The particular set of genes you have
• What does phenotype refer to?

  Characteristics of an individual determined by genes
• How do genes and environment interact to determine phenotype?

  Both genes and environment influence phenotype
• What is neurochemistry?

  Chemicals in the brain that regulate function
• What role do genes play in behavior?

  Genes influence behavior through biological processes
• What are chromosomes made of?

  DNA and proteins
• What is the relationship between genotype and phenotype?

  Genotype plus environment equals phenotype
• How does natural selection relate to behavior?

  Natural selection influences behavioral traits
• What are the key components of the biological approach?

  • Focus on genetics and neurochemistry
  • Emphasizes the role of environment
  • Studies the interaction of genes and behavior
• What is the significance of studies on twins?

  They show genetic and environmental influences
• What insights do neuroimaging studies provide?

  They reveal brain areas associated with behavior
• How do hormones influence behavior?

  Hormones play a crucial role in behavior
• What is the impact of a low protein diet on phenotype?

  It can lead to a specific phenotype
• How does the biological approach contribute to mental health treatment?

  It helps develop effective treatment strategies
• What challenges does the biological approach face in understanding behavior?

  Separating nature from nurture is complex
• What is the role of scientific bias in the biological approach?

  It can affect objectivity in research
• How does the biological approach view free will?

  It suggests behavior is largely predetermined
• What problems arise from separating nature from nurture?

  It complicates understanding of behavior
• How does the biological approach enhance treatment effectiveness?

  By understanding biological factors influencing behavior
• What is the relationship between genetic predisposition and behavior?

  Genetic predisposition influences behavioral outcomes
• How do environmental factors interact with genetics?

  They shape the expression of genetic traits
• What is the significance of understanding biological factors in psychology?

  It leads to more effective interventions
