Conclusion: The results show that the verb conveyed an impression of the speed the car was traveling and this altered the participants' perceptions.

It was the same one for which she would later become known: Who abused Jane Doe?

One of the main disadvantages of the cognitive psychology is that it refers to a process that we cannot directly observe, as it relies heavily on inference. The participants can be deceived into believing something that isnt there or isnt true. Marks AO3 9-10 A thorough evaluation of both strengths and weaknesses with well-developed and balanced arguments Clearly linked to the cognitive approach Structure is logical throughout An appropriate conclusion is reached based on evidence presented 6-8 A reasonable evaluation made of both strengths and weaknesses with well . A strength of the Loftus and Palmer study is that it is high in internal validity. Loftus and Palmer wanted to investigate how accurately eye witnesses can recall information on traffic accidents.

Loftus and Palmer argue that two types of information are influential in making up someone's memory. The findings into Eyewitness testimony were that research suggests that memory is easily distorted by questioning technique and information acquired after the event can merge with original memory causing inaccurate recall or reconstructive memory.
