Cognitive practical:
Whether STM remembers acoustically similar or dissimilar words better
hypothesis
there will be a difference in the number of acoustically similar words recalled in the correct order to the number of acoustically dissimilar words
IV
whether the words are acoustically similar or dissimilar
sample
10 students from our college - 5 male, 5 female
aim
to see if the STM remembers acoustically similar or dissimilar words better
DV
the number of words recalled in the correct order out of 10
design
repeated measures
procedure
ppts all seated in a row, equal distances from board
standardised script instructions read out to them, asked to sign form giving consent
10 words presented in order for 3 seconds, 2 second slide changeover,
5 second break
words displayed in a random order on board
ppts asked to write them down in the right order
repeated with other list of words
GRAVE
application
can help aid in memory and learning
internal validity
high - recalling word
order
rather than the words themselves eliminates potential bias in remembering specific words
reliability
easily replicable, standardised procedures (timings of slides etc.)
ecological validity
low as artificial lab setting, recalling order of words lacks mundane realism
generalisability
low as small sample of 10, all aged 16-17, can't be applied to other ages or people who speak other languages
ethics
shouldn't be any ethical issues - obtained informed consent through form, debriefed afterwards
