Questions & Answers

Q: What is sensation seeking?

Sensation seeking is a personality trait that reflects an individual's need for varied, intense, and exciting experiences. People with high sensation seeking scores are more likely to seek out thrilling activities.

Q: Is sensation seeking influenced by genetics?

Yes, research using twin studies has shown that sensation seeking has a strong genetic component, with heritability estimates of around 60%. This means that 60% of the variance in sensation seeking can be attributed to genetic factors.

Q: What is the role of the environment in sensation seeking?

While genetics play a significant role in sensation seeking, the environment also contributes to the remaining 40% of the variance. However, it is not the shared environment within the family but rather the unique life experiences and interactions with friends and peers that shape sensation seeking behavior.

Q: Are there any biological indicators of sensation seeking?

Yes, a dopamine receptor gene has been found to be related to sensation seeking. This suggests that sensation seeking behavior has a long evolutionary history, possibly dating back thousands of years.

Summary & Key Takeaways

• Sensory deprivation studies have shown that humans require sensation stimulation as much as food and water.

• The sensation seeking trait varies among individuals, with some needing more variety and intensity of stimulation than others.

• Research has found a strong genetic basis for sensation seeking, with heritability estimates of around 60%.
