A researcher asks adult research participants to vividly imagine tripping at a dance recital as a child. This incident never really occurred. Given past research, of the participants will later recall the event as something that actually happened.

The correct answer is one percent

Childhood memories are easily confused or altered, so in this case it is easy for some of the research participants to see this event as true and that it was part of their life, because childhood memories are usually vague and generally change so much by understanding of what happened at the time and the entire context.

explanation:

allergens: overstimulate the nerve system

neurotics: attack nerve cells

mutagens: damage or otherwise alter dna sequence

generators: cause defects during growth and development  

carcinogens: cause unchecked cell growth

i hope you get the idea according to me these are the effects that happened.
