What type of study was Yuille and Cutshall?

real life case study
Evaluation: A real life case study by Yuille and Cutshall (1986) contradicts the results of Loftus (1979) and the weapon focus effect. Yuille and Cutshall investigated the effect of anxiety in a real life shooting, in which one person was killed and another person seriously wounded.

Who are Yuille and Cutshall?

Yuille and Cutshall was the first investigation in witness testimony to use real witnesses of a real incident. Eyewitnesses aren’t as inaccurate as laboratory studies suggest. The long-term accuracy was possibly due to the incident being memorable and unusual.

When was eyewitness testimony first used?

This body of research has its programmatic origins in the mid- to late 1970s, but it received a large boost to its credibility in the 1990s, when forensic DNA testing began to uncover convictions of innocent people. Over 75 percent of these exonerations are cases involving mistaken eyewitness identification.

What does Elizabeth Loftus say about eyewitness testimony?

Loftus also shows that eyewitness memory is chronically inaccurate in surprising ways. An ingenious series of experiments reveals that memory can be radically altered by the way an eyewitness is questioned after the fact. New memories can be implanted and old ones unconsciously altered under interrogation.

Is Yuille and Cutshall a field experiment?

Yuille and Cutshall’s experiment had ecological validity as it’s a field study (in a real environment and a real situation), meaning the behaviour was more likely to be spontaneous and natural.

Is Yuille and Cutshall a case study?

Journal of Comparative Neurology and Psychology, 18: 459–482. Yuille, J.C., & Cutshall, J.L. (1986). A case study of eyewitness memory of a crime.

What did Yuille and Cutshall find?

However, a study by Yuille and Cutshall (1986) contradicts the importance of stress in influencing eyewitness memory. They showed that witnesses of a real life incident (a gun shooting outside a gun shop in Canada) had remarkable accurate memories of a stressful event involving weapons.

What type of evidence is more reliable?

The variety of physical evidence is virtually unlimited, as is the uniqueness of the crime. Physical evidence is generally much more reliable than testimonial evidence.

What percentage of eyewitness testimony is accurate?

In a recent review of the literature, the authors reported across 15 experiments, suspect identifications made with high confidence were, on average, 97 percent accurate!

Can you trust eyewitness testimony?

Research has found that eyewitness-identification testimony can be very unreliable. Although witnesses can often be very confident that their memory is accurate when identifying a suspect, the malleable nature of human memory and visual perception makes eyewitness testimony one of the most unreliable forms of evidence.

What percent of eyewitness testimony is accurate?

Studies have shown that mistaken eyewitness testimony accounts for about half of all wrongful convictions. Researchers at Ohio State University examined hundreds of wrongful convictions and determined that roughly 52 percent of the errors resulted from eyewitness mistakes.

Why have a field experiment?

The purpose of field experiments being conducted in the natural environment is to produce findings that are more realistic or applicable to the general population.

What did Yuille and Cutshall do in 1986?

Yuille & Cutshall (1986) carried out a study to demonstrate the reliability of memory that challenged the findings of Loftus & Palmer (1974).
