Memory Test Flashcards
What is personal investigation 1 about?
If recalling memory is better or worse with instrumental music playing or in silence
What is the IV?
Whether participants encode words with instrumental music playing or in silence
What is the DV? (1)
Amount of words recalled accurately from a word list of 25
What are the confounding variables? (1)
Participant variables
SEN students (dyslexia, hard of hearing)
What are the extraneous variables? (1)
Temperature
Time
Weather
What type of hypothesis is it? (1)
Directional hypothesis
What is the directional hypothesis? (1)
There will be an increase in recall of the 25 words when the participant learns and recalls them whilst listening to instrumental music compared to those who learn with music and recall with silence
What type of method is it? (1)
Lab experiment
What is the experimental design? (1)
Independent groups
What is independent groups? (1)
Each participant only takes part in one condition randomly allocated to either experimental or control group
Advantages of independent groups (1)
Less demand characteristics
Less materials
Time effective
No participant variables
What makes up the target population (1)
Sixth form students
Who is our sampling frame (1)
Sixth form students at notre dame
What was the sampling technique? (1)
Opportunity sampling
What were the ethics? (1)
Privacy
Deception- give debrief
Right to withdraw
Informed consent - age
Protection from stress, anxiety- don’t overwhelm with a range of different questions
How will you ensure internal reliability? (1)
Standardised procedures
Word list
Time for recall
Same sound/ music
How will you ensure external reliability? (1)
Test retest
What validity issues will be in your study? (1)
Researcher bias
Demand characteristics- independent groups less likely to work out the aims
What is the measure of central tendency? (1)
Mean
What stats test was used? (1)
Mann Whitney U Test
What was the observed value? (1)
221
What was the critical value? (1)
138
Were the results significant? (1)
The observed value (221) is greater than the critical value (138) so the results are non significant as for this test, the observed value had to be less than the critical value (one failed p<0.05)
This means we accept the bull hypothesis and reject the alternative hypothesis
What are the conclusions? (1)
The effect of context on recall performance does not spend on auditory conditions the material was learnt under
No difference
Two ways to improve (1)
Participant engagement
- talking during the task
Standardised procedure
- not all students follow rules
- lack of ecological validity
