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. Outline the possible sampling technique that may have been used in this study. For example, Loftus and Palmer found eye witness recall was easily susceptible to misleading information and would provide inaccurate information as a result of this. control, ecological validity, reliability The owner freed himself and picked up a revolver.

They aimed to show that the cues within leading questions could distort eyewitness testimony accounts. Researches by Loftus and Palmer (1974) have shown that memories on eye witness testimony are unreliable. Copyright Get Revising 2023 all rights reserved.

As an psychological explanation, the reconstructive memory If you give misleading information in a police investigation, it could lead to the wrong person being convicted or accused of the crime, and the actual person who committed the crime getting away with it. Not a true reflection of the experimental method inference, but the weaknesses of low validity! This assignment includes; Strengths, examples and weaknesses of the following psychological research; Bandura et al, Skinner & Loftus and Palmer.In order discuss and come to a conclusion as to why ecological validity is important in psychological research. Participants viewed video clips rather than being present at a real-life accident. In the early experiments on the misinformation effect(see, e.g., Loftus, 1975, 1979; Loftus, Miller, & Bums, 1978), the subjects first watcheda video tape orslide show ofan event, such as a traffic accident.

Control and thus allowed for the accurate measurement of variables, thus more objectivity and guns the specific did. Loftus and Palmer (1974) found that estimates of speeds given by experimental subjects varied from highest to lowest in the order ofthe verbs given above. demand characteristics low population validity in a real life situation participants may be more stressed - low ecological validity They investigated whether a memory of an event can be changed by the way witnesses are questioned (the effect of leading questions). The central goal of Loftus and Palmers experiment was to establish the extent to which language influenced the perception of reality. Loftus and Palmer gave two possible explanations for the results: 1. Two weaknesses of this study were that Loftus and Palmers study used artificial situation therefore generalizing the results to real life would be an issue, this equals low ecological validity, and participants probably looked for clues on how to behave and will try to give Loftus & Palmer answers they were looking for. The independent variable was the wording of the question, and the dependant variable was the speed reported by the participants. The essay's introduction, body paragraphs, and the conclusion are provided below. Research on the misinformation effect has a long and rich history in the human memory literature, beginning with the pioneering work of Loftus (1975; Loftus & Palmer, 1974 ). bear little relation to a real court scenario); participants in research may be more . Their two experiments consisted of 45 and 150 American students. Study 2: What were the mean speed estimates?

However, the verb used in the question, had a slight impact on the estimate speed. loftus and palmer strengths and weaknesses. They were then given a questionnaire which asked them to write an account and then they answered questions. A weakness of the cognitive approach is that, as lab studies are used, there is a lack of ecological validity with this research and so cognitions are being tested artificially. A further problem with the study was the use of students as participants. Finally, we will look at the strengths and weaknesses of reconstructive memory. Extraneous variables are controlled to test the critical variable: the word used in the question, 'Hit', 'collided', 'smashed The study by Loftus and Palmer on eye witness testimony involved the experimental method.
