There is an ongoing debate in the field of psychology regarding the validity of children as witnesses. Issues surrounding suggestive questioning and accurate memory recall are just a few of the concerns related to using children as witnesses. According to psychologists, “eyewitness accuracy” is also affected by system variables.
The term “system variable” refers to those factors that are under the control of the criminal justice system. According to the course textbook, the term “estimator variable” refers to the factors that are beyond the control of the justice system. To test witnesses deception to the crime reported is an important step in justifying any crime. Polygraph (or as some refer to it—the “lie detector”) has been used for many years to detect deception. According to the course textbook, the polygraph measures physiological arousal in combination with a specific questioning strategy.
Conduct research on children as witnesses, eyewitness accuracy, and polygraph tests. Based on your understanding, address the following:
