Factors influencing eye witness testimony
Understanding Eye Witness Testimony
- Relies heavily on the factors influencing the accuracy and reliability of human memory.
- Associated with the misinformation effect, where incorrect information obtained post-events can alter memories of the event.
Role of Stress and Anxiety
- Stress and anxiety at the time of the event can significantly impact the accuracy of the eye witness testimony.
- High levels of stress or anxiety can lead to a focus on the central details of the event, a phenomenon referred to as weapon focus.
Effects of Repeated Recall
- Repeated recall or reconstruction of the event can lead to distortion of the original memory.
- Each reconstruction runs the risk of incorporating associated, but incorrect, details into the memory.
Influence of Leading Questions
- Leading questions, or those that suggest a certain answer, can seriously impact the accuracy of an eye witness account.
- Phrasing and tone of the question can direct a witness’s recall in a specific direction.
Impact of Stereotypes and Prejudices
- Stereotypes, prejudices, and personal biases can all influence the subjectivity of an eyewitness testimony.
- The witness’s perception of the event can be influenced by previous experiences and pre-existing notions, causing misleading testimony.
Role of Confidence and Self-esteem
- A witness’s level of confidence or self-esteem can considerably affect their testimony.
- Over-confident witnesses may distort actual events while low self-esteem may result in the suppression of actual events.
Effect of Time Elapsed
- The longer the time between the event and recall, the more likely that the witness will experience memory decay.
- This reduction in the quality of the memory makes it increasingly susceptible to distortion and misinformation.
