Q
aims
A
- To see if false memories could be implanted in people
- To see if false memory of loving asparagus previously makes asparagus more appealing by sight
2
Q
procedure
A
Session 1
- Participants assigned to 1 of 2 groups (Love and Control group)
- Upon arrival, participants were told that their data would be entered into a computer, that would later generate a personal profile for them
- Participants then completed 5 questionnaires: FHI, Food preferences Questionnaire, Restaurant Questionnaire as well as two filler questionnaires which included personality Questionnaire and Desirability Scale
- Filler questionnaires were to distract from true aim of experiment.
Session 2
- Participants returned to the location, where they received false feedback on their performance from Session 1.
- The critical item was embedded in their “computer generated” profiles which read: “You loved asparagus the first time you ate it.”
- Participants then viewed 20 slides each of which was displayed for 30 seconds, and completed 4 ratings of each slide. The slides contained photographs of common food including the critical item Asparagus.
- The photos were rated based on their degree of appetite or disgust, and the properties of the photograph’s origins.
- Participants then completed the FHI, Food preferences questionnaire and Restaurant Questionnaire for the second time.
- Also additionally completed a memory of belief questionnaire

- 62% female
- Mean age 19.9

Q
results
A
- Results show positive false memories can be implanted in people
- The mean confidence of the love group liking asparagus increased from 1.7 to 4.2 (by 2.5 points) whilst for the control group increased from 1.45 to 2.52 ( by 1.1 points)
5
Q
conclusion
A
- Experiment showed that people can have positive false memories implanted in them which had consequences towards their liking of asparagus
6
Q
IV & DV
A
IV: - False information of false memory of liking asparagus as a child
DV: How much the participant liked asparagus
7
Q
control variables
A
Procedure/method and lab environment
8
Q
method
A
- Self report (Questionnaires)
- Lab experiment
9
Q
strengths
A
- Very replicable due to standardized procedure, meaning investigation can be repeated for higher reliability
- Quantitative data is objective and unbiased, hence the high validity of the experiment
10
Q
weaknesses
A
- Lab environment and questionnaire is not representative of real life, hence low ecological validity
- Not generalizable as participants were all from same university and mostly female (gynocentric but not that much at 62%)
11
Q
ethics
A
Participants deceived about aims of experiment as well as their food preferences which is manipulation
- Participants were not debriefed
- Uninformed consent
