๐ The nature versus nurture debate analyzes the influences on personality development.
๐งฌ Evolutionary psychology suggests that our personality is shaped by traits favored by our environment.
๐ฑ Genes and environmental factors both play a role in the development of personality.
๐งฌ Our physical biology, including personality, can be influenced by the environment.
๐ฅ Identical twins studies help determine the contribution of genetics and environment to traits.
๐งฌ๐ฟ Heritability measures the extent to which traits are influenced by genes or environment.
๐งฌ Some personality traits are influenced by genetics, such as social closeness, achievement orientation, traditionalism, and imagination.
๐งช A specific gene, dopamine 4 receptor gene, can influence the trait of thrill-seeking and enjoying novelty.
๐ฏโโ๏ธ Real-life examples, like the gym twins, demonstrate that traits can be passed down through genes.
๐ Our genes may be closely correlated with our personality traits and decisions we make.
๐ง Brain chemistry plays a significant role in our reactions and assessment of the environment.
๐ค The size of certain brain sections, like the amygdala, may influence specific personality traits.
๐ง Our brains have the potential to change and cause our personality to change.
โ ๏ธ The case of Phineas Gage demonstrates how a brain injury can severely affect personality.
๐ฌ The biological model of personality is supported by evidence from brain chemistry and brain injuries.
๐ง Our brain chemistry can be changed through external factors like drugs and smartphones, impacting our personality.
๐ Neuroplasticity allows us to rewire our brain, enabling us to change our brain chemistry and ultimately our personality.
๐งฌ๐ฅ The nature versus nurture debate suggests that both biological factors and environmental influences shape our personality.
๐ง Our personality can be influenced by both nature and nurture.
๐ The environment and culture we grow up in can shape our personality traits.
