- 1KEY DEFINITION: Eyewitness Testimony/Leading Questions (3 points)* EWT - when someone who has witnessed a crime is asked to give an account of what they saw. Often can be very inaccurate e.g. due to leading questions
* Leading questions - suggest to the witness that a particular answer is required. Can alter witnesses perception & thus recall of the event
* Can have a retroactive interfering effect: new info implied in the question gets confused with existing knowledge - 2CONTEXT ONE: Bartlett (reconstructive memory)* Memory isn't accurate but instead built up of our own experiences and expectations
* Ppts presented with folk tales then asked to recall info on it at varying time intervals
* Length of recall decreased as time went on, some aspects were forgotten & others changed to fit their schema - 3CONTEXT TWO: Marshall (air force personnel)* Estimate speed of a vehicle (knew in advance they would be asked to estimate the speed)
* Estimates ranged from 10-50 mph.
* Large variability = variables can cause these inaccuracies - 4CONTEXT THREE: Filmore (video of a car accident)* Asked to estimate how fast the cars were travelling
* Either using the words smashed/hit
* Smashed condition = higher speed estimates
* Demonstrates influence of the verb used over the speed - 5AIM1. Investigate if the form of a question can systematically affect a witnesses' answer to that question
2. If using the word smashed or hit would have consequences on ppts memory a week after the original event occured
