What does the biological approach in psychology emphasize?
Genetics, neuroanatomy, neurochemistry, and evolutionary influences in understanding behaviour.
The approach proposes that behaviour is inherited through genes. Understanding genetic terminology is crucial for studying heritability.
Adaptive Behaviors: Biological psychologists argue that many behaviours have evolved because they increase the chances of survival and reproduction.
Specific brain and nervous system structures are linked to different behaviours and functions:
What does the biological approach in psychology emphasize?
Genetics, neuroanatomy, neurochemistry, and evolutionary influences in understanding behaviour.
What is the difference between genotype and phenotype?
Genotype is the genetic makeup; phenotype is the observable traits influenced by genotype and environment.
What type of studies estimate the heritability of behaviour?
Twin and family studies.
How does evolutionary theory explain behaviour?
Behaviours evolved because they increase survival and reproduction chances.
Which brain structure is involved in complex thinking?
The cerebral cortex.
Name two components of the limbic system and their functions.
Amygdala (emotion), hippocampus (memory).
What role does the hypothalamus play?
Regulates basic drives such as hunger and thirst.
What neurotransmitter is linked to motivation and reward?
Dopamine.
Which neurotransmitter is associated with mood regulation and depression?
Serotonin.
What neurotransmitter deficiency is linked to anxiety?
GABA.
What does cognitive neuroscience study?
How brain activity supports cognitive functions like memory and language.
What brain areas are linked to speech production and comprehension?
Broca’s area (production) and Wernicke’s area (comprehension).
