This study is also referred to as:
Fisher et al., (1986)
Fisher and Geiselman (1986)
Geiselman et al., (1986)
Fisher et al., (1986) focuses on police interviews of witnesses.
What is an interview?
An interview is simply trying to elicit information from a person or witness, while keeping the information valid. This is easier said than done. You may remember two studies from AS: Loftus et al., (1974) and Samuel and Bryant (1984), which demonstrate this. Firstly, Loftus showed the impact that leading questions could have upon participant recall and she concluded that an actual change in memory had occurred. Memory is easily malleable, changing how a question is asked can change the memory itself. Secondly, Samuel and Bryant showed the impact of repeating the same question. Repeating the same question to children will cause them to completely change their answer, even if their answers were perfectly correct.
Loftus et al., (1987) – Some Facts About “Weapon Focus”, Journal of Law and Human Behaviour 11 (1), 55–62
This is the second study we look at from the ‘Interviewing Witnesses’ section of ‘Making a case’. As part of your OCR A2 Psychology Exam. It is further categorised into ‘Weapons Focus and Factors Affecting Reconstruction.’
“‘Weapon Focus’ refers to the concentration of a crime witness’s attention on a weapon, and the resultant reduction in ability to remember other details of the crime.”
When a weapon such as a gun is present during a crime. Witness recall of the offender is significantly reduced. The reason behind this is witnesses tend to focus on the weapon, not the offender. This is due to attentional narrowing, which Loftus believed is present due to evolution.
Good news! There is not a background study for this study!
