2. Operationalised IV and DV
3. Hypothesis
4. Conditions - control + experimental groups
5. Design
6. Collect data + analyse it
7. Accept or reject hypothesis

Question 2

What are the research methods in cognitive psychology?

Answer 2

Lab experiments, field experiments

Question 3

What needs to be done when analysing results?

Answer 3

Need to use descriptive statistics + graphical representation

Question 4

Define abstract:

Answer 4

Summary of background theory/research, aims, hypothesis, method, results, + discussion

Short paragraph overview of entire report, do at end

Question 5

What does the introduction include?

Question 6

What are we basing our investigation on?

Answer 6

Baddeley investigation

Question 7

Whats in our introduction? (look in booklet for more details)

Answer 7

Memory definition, works in linear sequence, 3 separate stores

Glanzer + Cunitz = Test and results
Peterson + Peterson = Test and results

Question 8

What is the aim of our investigation?

Answer 8

To investigate the importance of maintenance rehearsal as a way to transfer information from STM to LTM using interference task to prevent rehearsal

Question 9

What is our hypothesis? (Directional)

Answer 9

Ppts who rehearse significantly more words will score higher out of 10 on memory recall compared to ppts with an interference task to prevent rehearsal

Question 10

Why did we choose a directional hypothesis?

Answer 10

Theres evidence from studies to prove there is significant increase in results when rehearsed

Question 11

What is the sampling method?

Answer 11

Opportunity - Anyone willing and free to take part

Question 12

What is the operationalised IV?

Answer 12

Rehearsal and no rehearsal, saying words out loud and saying alphabet backwards for 30 secs

What is the design + reason for choosing it?

Answer 14

Repeated measures, reduces ppt variables

Question 15

What are situational/ppt variables that were controlling?

Answer 15

1. Test ppts individually
2. No distractions
3. Word list shown visually + said, common words used
