It is reasonable to argue that the students in their experiment were less experienced drivers, who may be less accurate at estimating speeds. 7. Background.

Findings: Participants who were asked how fast the cars were going when they smashed were more likely to report seeing broken glass. Evaluation: This is a weakness because it can be argued that the findings from artificial laboratory research settings such (as Loftus' study) may not be applicable to real life EWT behaviour, which weakens the research as support for the role of misleading information affecting the accuracy of EWT.

The participants in the smashed condition reported the highest speed estimate (40.8 mph), followed by collided (39.3 mph), bumped (38.1 mph), hit (34 mph), and contacted (31.8 mph) in descending order. real life a largely unexpected. Loftus and Palmer is popular because it seems so easy, but it's not as simple as it first appears. Journal of Verbal Learning and Verbal behavior, 13, 585-589. Experiments allow for precise control of variables. the control group). Therefore allowing them to determine the cause and effect i.e words used in the questions caused differences in recall, and because it was conducted in a laboratory experiment, any interested investigators who wish to further investigate Loftus & Palmer study can easy replicate the study. As an psychological explanation, the reconstructive memory Background. Improve, we had to work in a team of 4. Quickly memorize the terms, phrases and much more. - Another group was asked, "About how fast were the cars going when they hit each other?" remembered that they had been asked about the cars "smashing" - The question was manipulated as it was very controlled, as it did not word the questions in such a way as to suggest. for real events.

Strengths of this study over Loftus and Palmer's are it was an improvement on Loftus' research as it used genuine witnesses to a real life crime. INTRODUCTION The accuracy of memory has been studied at length. The Loftus and Palmer study is one of the most interesting experiments ever conducted in psychology.

In this and other publications (Loftus et al., 1975; Loftus & Zanni, 1975), Loftus and her colleagues have demonstrated that, at a minimum, postevent questioning Evaluation: This is a weakness because it can be argued that the findings from artificial laboratory research settings such (as Loftus' study) may not be applicable to real life EWT behaviour, which weakens the research as support for the role of misleading information affecting the accuracy of EWT.
