Cognitive (CONTEMPORARY) - memory - GRANT Flashcards
(34 cards)
Context dependent memory
Recall of information is enhanced if we are recalling the information in a similar context to how we learn it
Recall
Retrieving information with very few prompts
Recognition
Comes with prompts
Background
Grant was interested in applying the theory of context dependent memory to students
Aim
Test for context dependency effects caused by the presence or absence of noise during learning and retrieval of meaningful material
Research method
Lab experiment
Experimental design
Independent measures
IVs
- condition of reading the article (noise/silent condition)
- testing condition (matching or mismatching to reading condition
4 conditions
- Learn with noise present and recall with noise present
- Learn in silence and recall in silence
- Learn with noise present and recall in silence
- Learn in silence and recall with noise present
Dv
Performance on a short answer recall test and a multiple choice test
Sample
Conducted by 8 psychology students who served as experimenters
Each experimenter recruited 5 acquaintances who served as the participants. 39 participants. 17 females and 23 males aged between 17-56 with mean age 23.4
how participants were assigned to conditions
each experimenter responsible for 5 participants, one participant per condition and then the 5th was randomly assigned to any 1 of the 4 conditions
standardized instructions
during verbal standardized instructions it was outlined to the participants that this research was part of a class project and that their participation was voluntary. They were informed that short answer and MCQ would follow the reading of the article
procedure
participants were asked to read an article once as if reading for a class assignment being allowed to highlight and underline
all experimenters had there own casette players and headphones and made participants wear headphones while they read the article
reading time was recorded by the experimenter and there was a 2 minute break between finishing the reading and being tested
in the test all participants were tested with the short answer questions first to ensure that it was recall of the article not prompted by the options in the MCQ
participants again all wore the headphones for the testing phase but again half were hearing nothing while the other half had the cafeteria noise
some were in matching conditions (learn and recall in the same environment and some were were in mismatching conditions (learning and recalling in different environments
at the end of the testing participants were debriefed about the true nature of the study and the entire procedure lasted 30 minutes
describe the article
2 pages with 3 columns of text to a page on psychoimmunology
describe the two conditions
In the silent condition nothing was played through the headphones an were told they would not hear anything but still had to wear them
In the noise condition noise was played at moderately loud level and participants were told to ignore the noise
explain why there was a 2minute gap in between reading the article and answering the questions
to prevent short term memory effects
describe the short answer questions
10 questions tested in order as the information appeared in the article
describe the MCQs
16 questions each with aa correct option and 4 alternatives
findings - reading speed
no significant difference in reading speed between the silent group and the noisy group
findings - performance
performance was better when the participants were in matching conditions
findings - matching conditions
there was no difference between the two matching conditions
conclusions
- memory in context dependent, memories are formed with traces of the environment which can then improve recall of said memory for example on the short answer questions out of 10 on the matched condition the mean was 6.7 compared to 4.6 on the mismatched environment
- studying and testing in the same environment leads to enhanced performance thus students are likely to perform better in exams if they study for them with a minimum background noise as there are no overall effects of noise on performance
strength of research method
lots of controls to remove extraneous variables For example the standardized verbal instructions and same cafeteria sound in the headphones means we can determine a cause and effect that any difference in test performance was down to the match/mismatch of the learning and recall conditions
