GRANT Flashcards
Aim of the study?
Research method?
IV?
DV?
1) Investigate context dependant memory effects on both recall and recognition.
2) Lab experiment.
3) - Participant read article in silence/noisy.
- Participant tested in matching/mis-matching conditions (silent/noisy).
4) Participants on recall test + recognition test.
Define context dependent memory?
Refers to the phenomenon of how much easier it is to retrieve certain memories when the ‘context’ around the memory is the same.
What was the experimental design?
Test/reading conditions?
1) Independent measures.
2) Matching/mismatching - noisy/silent .
The sample?
How was the sample obtained?
1) 39 participants (17F/23M)
2) 8 psychology students recruited 5 participants (opportunity).
Data type?
How was the procedure standardised?
1) Quantitative
2) Both conditions wore headphones + read the same article + only read the article once.
Describe the test?
1) Recall - 10 short answer questions.
Recognition- 16 multiple choice questions (headphones worn)
2) Students should learn in a similar environment to the environment they will be tested in, as they perform better - noise had no effect on performance.
Conclusion?
Students should learn in a similar environment to the environment they will be tested in, as they perform better - noise had no effect on performance.
EVALUATION
Research method - Lab
Strength?
Weakness?
1) High validity - standardised procedures (wore headphones/no extraneous variable)
2) Low ecological validity - unnatural environment (classroom) - shows demand characteristics
EVALUATION
Data - quantitative
Strength?
Weakness?
1) Easy to view + analyse results (displayed in a table).
2) Vague + not rich in detail (doesn’t explain why participants perform better in matched conditions).
EVALUATION
Validity
Strength?
Weakness?
1) High internal validity - avoids order effect (independent measures design).
2) Low population validity - 39 participants - not generalisable.
EVALUATION
Reliability
Strength?
Weakness?
1) High internal reliability - easy to replicate (standardised procedures).
2) Low external reliability (only students).
EVALUATION
Sample
Strength?
Weakness?
1) High population validity - large age range
2) Low population validity - not generalisable (all students - used to revising)
EVALUATION
Sampling method - opportunity
Strength?
Weakness?
1) Convenient + quick to gather (experimenters found 5 people each).
2) Cannot gain desired participants (relies on who’s avaliable).
EVALUATION
Ethnocentrism?
Practical applications?
Ethics?
1) students have an advantage (familiar of revising)
- Small sample = less diversity
2) schools = teaching children in silence to improve their performance on a test.
3) confidentiality (no info)
