Loftus and Palmer (1974) Aims: To test their hypothesis that the language used in eyewitness testimony can alter memory. Weaknesses: - Laboratory experiments may have low external validity (i.e. research.

The results from experiment two suggest that this effect is not just due to a response-bias because leading questions actually altered the memory a participant had for the event. She has conducted research on the malleability of human memory. They were then later asked if any broken glass was present in the crashes. Loftus and Palmer (1974) Experiment 2 Experiment 1 - Car accident Evaluation Strengths Weaknesses Both parts of the experiment are laboratory experiments which means the extraneous variable can be controlled. As you can see, its possible to manipulate sympathies, animosities, and the degree of relevance given to an event, etc. Loftus & Palmer (1979) is a good example of a lab experiment with an independent groups design.
