Loftus And Palmer- Evaluation Flashcards
What are the 3 main evaluation issues?
- low mundane realism
- demand characteristics
- lab based
Low mundane realism
Therefore low levels of ecological validity because the experiment involved an artificial task by watching videos of they were real life car crashes it might have a more emotional attachment
Demand characteristics
The participants were palmers students and therefore they most liekly knew and santed to give their tecaher the right answer to aid her investigation
What did palmer do the try and minimise demand characteristics?
Added a filler question at the beginning to mislead the ps
No population validity
Cant generalise the results to a wider population because she only tested on her students
Ethical issue
The ps dont really have a right to withdraw because they might feel like they are obligated to take part because they are her students
