Cognitive Practical Flashcards
What was the aim of the experiment?
To test whether or not schemas aid in the recollection of memory better when given titles on a sample of text
Give a one-tailed hypothesis for the experiment.
Participants will obtain a higher score when given a title than those who aren’t given a title
Give a two-tailed hypothesis for the experiment.
There will be a difference in scores in participants who are given a title and those who aren’t given a title
Give a null hypothesis for the experiment.
There will be no difference in score between participants who are given a title and those who aren’t given a title
What was the sample for he experiment?
16 16-17 year old psychology students (2 boys, 14 Girls) from NSFC.
What was the procedure for the experiment?
- 16 students in a classroom (lab setting) conducted in an independent measures design
- All students provided with a paragraph (8 with a title at the top named “Doing Laundry”, 8 without)
- Given 2 minutes to memorise the paragraph
- Asked an irrelevant question about Christmas as an interference task
- Given 3 minutes to recall as many words as possible
What were he results of the experiment?
The mean number of key words remembered:
With a title - 7.38
Without a title - 5
Is the study generalisable?
No because:
- All psychology students
- Only 2 boys
- All within the same age range
Is the study reliable?
Yes because:
- Standardised lab conditions (replicable)
- Controlled
Is the study valid?
Yes because:
- Independent measures design ~ no order effects
- Standardised ~ no extraneous variable
However, it was conducted in an artificial setting therefore is low in ecological validity
Is the study ethical?
No because students didn’t give informed consent, however they were debriefed at the end and weren’t exposed to any harm.
