Original Investigation: On average, participants who are exposed to audio clips linking to extra pieces of information will have more accurate recall than those who are given the words alone.
Sample
Size:
- Year 10/11 SACE Stage 1 Psychology students in GIHS
- Total of 39 students
- Participants within the age range of 182-270 months
Limitations:
- limited sample that is too small to represent a population of a larger size, either the general population or the student body
- the participants involved are all psychology students, therefore their pre-existing knowledge may affect the outcome due to confirmation bias
Representativeness:
- not representative of a larger population
- participants are of a similar age range, attend the same school and all take SACE Stage 1 Psychology
Strengths:
- sample groups were randomly allocated, eliminating the chance of selection bias
-
Variables
Independent: the amount of extra info given to a participant to aid memory of the list of words
- group 1 received the list of 10 words alone
- group 2 received the list of 10 words, along with a definition for each
- group 3 received the list of 10 words along with a definition of each, as well as an emotive description
-
Controlled:
- the amount of time given to recall the words; each group was given 60 seconds to recall as many words as they could
- the list of words given to each group; each group was given the same list and the same amount of words
- the environment the practical was done in; each group had done their practical in similar if not exactly the same environment as each other
- the audio quality/features; the narrator was the same person throughout all audios, and the audio quality was consistent throughout
Extraneous:
- participant variables that could affect memory issues, such as lack of adequate sleep/poor sleep quality, emotional state, caffeine/sugar intake, etc.
- participants' familiarity with certain words, allowing them to be able to recall them easier and lessening the impact of the IV on the DV
Strengths:
- because of set IV, DV and CVs, this experiment is considered fair, with less uncontrollable variables, providing more accurate and consistent results
- overall provides more accurate results which can be used to prove causation and/or correlation
Limitations:
- each participant's memory recall will differ even by a slight bit, making it hard for researchers to account for to keep their results consistent; there is bound to be some form of an outlier
-
Ethics
Informed consent:
participants were given information about the practical before volunteering/consenting.
Voluntary participation:
participants were given the option whether or not to participate. underage participants required a guardian's signature before partaking.
Confidentiality:
participants were assigned an ID number to remain anonymous during the practical and in the final results.
Right to withdraw:
participants were given the choice to withdraw at any point of the practical if necessary.
Accurate reporting:
participants were told to individuallly report their own results, therefore it is hard to determine accuracy.
