Biological Flashcards
Genotype and phenotype
Genotype = Genetic makeup
phenotype = How the genes are expressed in the environment
Twin studies
Monozygotic twins = 100% concordance rate
Diazygotic twins = 50% concordance rate
What does the bioloigicak approach look at
Biological structures and processes
Evolution
Genetics that enhance survival are passed down to future generations ( natural selection )
Studies used in the bio approach
Family studies
adoption studies
Twin studies
Strengths of bio approach
Scientific methods
- uses PET scans
-increases validity
-provides credibility to psychology
- reliable
Real life application
- Has led to increased understanding of biochemical process in the brain
- development of drugs to cure medial issues e.g. depression
-sufferers are able to manage their condition
Limitations
Casual conclusions
- focuses on association- e,g offers explanation for illnesses based on neurotransmitters in the brain
Ignores ither explanations
-e.g role of cognition
