Psychology - Cognitive Area Loftus and Palmer (1974) Part 2
This deck covers key concepts and evaluations from the Loftus and Palmer (1974) study on cognitive psychology, focusing on memory distortion and research methodologies.
What are the possible findings from this study?
The verb used in a question influences a participant’s response i.e. the way a question is phrased influences the answer given. People are not very good at judging vehicular speed. Misleading post event information can distort an individual’s memory

What are the possible findings from this study? | The verb used in a question influences a participant’s response i.e. the way a question is phrased influences the answer given. People are not very good at judging vehicular speed. Misleading post event information can distort an individual’s memory |
Evaluate the research methods used in Loftus and Palmers study? | Controlled laboratory experiment which fulfilled the scientific criteria of theory, control, evidence and replication. However, experiment lacks ecological validity due to artificial setting. |
Evaluate the data collected in Loftus and Palmers study? | This study collected and reported quantitative data and this enables results to be easily summarised, an average of the estimated speeds in experiment 1. Comparison between conditions was easier. |
What are the ethical issues in Loftus and Palmers study? | Slight degree of deception but participants knew it was a test of memory. The experiment was conducted ethically. |
Assess the validity of research by Loftus and Palmer. | A highly controlled laboratory experiment, high design validity. The procedure was standardised: questions, film clips, task. However as the participants know they are in a study this may have affected the outcome of the study. |
Assess the ecological validity of research by Loftus and Palmer. | Low ecological validity as it is carried out in a controlled artificial setting. Participants were told to remember what they had seen, in a real car crash individuals would not be consciously trying to remember what they have seen. In a real situation they would be under a lot more stress, the experiment had no emotional connection with the event. |
Assess the relaibility of research by Loftus and Palmer. | High internal reliability due to standardised procedure, replicated across multiple participants. This experiment has been recreated establishing test-retest reliability. Reliability in the findings as consistent results found that leading questions can distort memory. |
To what extent can Loftus and Palmers sample be seen as bias? | They were all collage students, lacks generalisbility to a larger sample. The students only represent a narrow age group, upper levels of family income and education. You need high cognative ability to gain entry in to university. Not all the sample may have been able to drive. |
What what extent can research by Loftus and Palmer be seen as ethnocentric | Cognitive processes such as reconstructive memory, depend upon the physiognomy of out brain and this is the same in all cultures. However, university students tend to have high cognitive function than the rest of the general populations and tent to come from upper and middle social classes. |
Discuss if this study supports psychology as a science. | Controlled laboratory experiment which fulfilled the scientific criteria of theory, control, evidence and replication. Cognitive area studies support this claim that psychology is a science discipline. |
Discuses the usefulness of research by Loftus and Palmer. | very useful, it showed that it is possible to distort eye witness testimonies. This has large repercussions with police. |
