Data type It is important to uphold ethical questions in order to test the hypothesis that verb Video of a traffic accident provided to them, ranging in duration from 5 30. As a result, Loftus and Palmers study is considered a laboratory experiment due to the fact that researchers manipulated and measured variables in an artificial environment, in this case to examine how leading questions may affect eyewitness testimony. and Scott, J. Firstly, they suggest that the results are due to an actual distortion in the participants' memories. 26-35 year-olds were most accurate ( 77%) and the elderly (age 65+) group were the least accurate ( 56% ). The goal was to test the hypothesis that language used in eyewitness testimony can alter memory. Demand characteristics, as the students were either paid $3.50 or given extra credit for participating, they may have feel the need to act in a way which the experimenter would want. The data type was both data types which meant they could analyse and Person B acted differently in both conditions. It is further categorised into Weapons Focus andFactors Affecting Reconstruction., Weapon Focus refers to the concentration of a crime witnesss attention on a weapon, and the resultant reduction in ability to remember other details of the crime..

Finding out that certain verbs caused different speed estimates really But watch out, the "car crash study" can cause major accidents if you're not careful. In addition, controlled experiments allow for the study to be replicated and this ensures that findings can be proved as being reliable. How does loftus and palmer link to the key theme 3:Buckhout (1980) A 13 second film clip of a mugging was shown on TV.
