You Can Inherit Fear?

The video explores the concept that fears can be inherited, not just learned, as suggested by Charles Darwin. It delves into phobias, a type of anxiety disorder, and discusses how genetics play a significant role in their development. Studies on twins show that phobias can be heritable, with evolutionary pressures influencing different types of fears. The video also covers genetic research methods like linkage analysis and highlights cognitive behavioral therapy as an effective treatment for phobias, regardless of their genetic or environmental origins.

What new perspective on fear is gaining attention, as opposed to the traditional view?

• Fears are purely learned through experience.

• Fears are a result of imagination.

• Fears can be inherited genetically.

• Fears are only related to childhood experiences.

How do psychologists define phobias?

• As a mild dislike of certain objects or situations.

What did the 1998 study on twins in Australia reveal about the fear of blood?

• It is entirely learned from personal experiences.

• It is not influenced by genetics at all.

• Genetics account for 71% of the variation in fear of blood.

• It is more common in fraternal twins than identical twins.

Why might some phobias be more heritable than others?

• Because they are more common in urban areas.

• Due to the level of education.

• Due to differences in evolutionary pressure.

• Because they are influenced by diet.

• Surgical intervention

• Hypnosis

• Cognitive behavioral therapy

• Medication therapy

What is the relationship between phobias and other anxiety disorders?
