The Atkinson-Shiffrin multi-store model of memory Flashcards
letters task
Apply the model to explain how you could recall the letters, despite the increase in the number of letters being presented. Reference the features of short-term memory and how they helped you complete the task.
Once info went from the SENSORY MEMORY to STM, it can remain there for a duration of 18-30 seconds allowing students to then write numbers down. The STM also has the capacity of 7+-2, however most students could memorise up to at least 5 letters at a time.
With reference to the duration and capacity of the three separate stores of the model, explain how you were able to complete PART B of the “Letters” task (able to recall and reorder the letters!).
The visual sensory info enters the SM for a brief moment then when students attend to the info it is transferred to the STM which will store a limited amount of info for 18-30secs, students will then recall knowledge of the alphabet from LTM to reorder the letters before writing them down.
Identify and justify the methodology and design used in this study
Controlled experiment, the casual relationship between two variables is tested seen through participants being exposed to two different conditions, therefore enabling researcher to compare both results.
A within-subject design is applied since participants complete every experimental condition
Suggest the sampling technique used in this study, and evaluate this technique.
non-random sampling, this technique is time and cost effective however, it is likely to produce an unrepresentative sample.
Identify the and justify brain area/s involved when you completed the action of writing down the letters on your page
Basal ganglia - has a role in storing and encoding procedural memories such as writing
Cerebellum - stores and encodes procedural sequence of precise movement and involved in motor control
Identify and justify brain area/s which would be involved if you completed a hypothetical PART C of the study, where you learn a list of 7 letters and must remember them until our next class where you are asked to recall them.
Hippocampus - primarily involved in encoding explicit memories
Neocortex - stores explicit memory
