Cognative practical Flashcards
What type of study is the cognative practical?
Laboratory experiement
What did the cognative practical want to find?
Can ps use different parts of working memory at the same time?
What was the experimental hypothesis of the cognative practical?
Participants will not be able to complete condition 1 which consisted of a dual task both using the phonological loop
What design was used for the cognative practical?
Repeated measures, this is because each participant carried out condition 1 and 2
What was the IV + DV of the cognative practical?
IV: Distraction task - Alternate from PL or VSS
DV: Number of digits they remember for that condition - each ps take 3 tests for their condition
How did you sample ps for the cognative practical? And how many were there?
- Oppurtunity sampling
- 7 ps ( 6M + 1F)
- Age range: 16 to 55
How did you overcome ethical issues in the cognative practical?
- Confidentiality, participants were kept confidential
- Right to withdrawn, were informed in consent form
What were the results of the cognative practical?
Mean - C1:0.43 C2:2.29
Willcoxen - ordinal data
T value = 0 Critical value = 3
T value is less therefore results were not by chance
What are the strengths of the cognative practical?
- Standadised procedure - used repeated measures design - each ps used the same conditions and therefore procedure was same for all
What are the weaknesses of the cognative practical?
- Lab experiement - Lacks EV due to artifical task - recalling digit strings - not everyday task
- Repeated measures design - chance of demand characteristics - order effects
What is an improvement of the cognative practical?
More realistic task - Shopping list - more ecologically valid
