The link to biological processes

• How might biology and personality interact in addiction?

  • personality traits (e.g. Impulsivity) are linked to dopamine function, which is key in addiction

  • Buckholtz et Al (2010) found that highly impulsive people had greater dopamine release when given amphetamines
• What does this suggest?

  • impulsive individuals may be more likely to develop addictions because they experience stronger dopamine-driven rewards
