PSYCHOLOGY AQA A-LEVEL PAPER 1 EXAM UPDATED 2025
WITH 100+ QUESTIONS AND 100% CORRECT ANSWERS//
GRADED A+
define memory VERIFIED ANSWER The process by which we retain
information about events that has happened in the past
define coding VERIFIED ANSWER format in which information is
stored in various memory stores
define duration VERIFIED ANSWER length of time info held in
memory
define capacity VERIFIED ANSWER The amount of information that
can be held in a memory store
what is the capacity of the sensory register? VERIFIED ANSWER
unknown but very large
What is the duration of the sensory register? VERIFIED ANSWER very
limited, 250ms
What is the coding of the sensory register? VERIFIED ANSWER raw
unprocessed information from all 5 senses
,What is the capacity of STM? VERIFIED ANSWER limited, 7+/- 2
chunks
What is the duration of STM? VERIFIED ANSWER limited, 18-30s
(P&P)
What is the coding of the STM VERIFIED ANSWER acoustic
What is the capacity of the LTM VERIFIED ANSWER unlimited
What is the duration of the LTM VERIFIED ANSWER lifetime
What is the coding of the LTM VERIFIED ANSWER semantic
Who investigated the capacity of STM VERIFIED ANSWER Miller
(1956)
describe Miller's study VERIFIED ANSWER aim - investigate capacity
of STM
method - reviewed published investigations into perception and STM
results - STM could cope with about 7 +/- 2 pieces of information
conclusion - organisation of info can extend capacity of STM
, What are the strengths of Miller's study? VERIFIED ANSWER -
research support, Jacobs conducted digit span test finding people could
remember 7.3 letters and 9.3 numbers
What are the weaknesses of Miller's study? VERIFIED ANSWER - not
precise, didn't specify how large each chunk could be so cant conclude
exact capacity, further research required
- didn't account for other factors, Jacobs found that Age increases STM
capacity
Who investigated the duration of STM VERIFIED ANSWER Peterson
and Peterson (1959)
Describe Peterson & Peterson (1959) VERIFIED ANSWER Aim -
investigate duration of STM in lab experiment with 24 students
Procedure - recall meaningless trigrams. To prevent rehearsal, students
count backwards in 3s/4s from random numbers, then recall
Findings - longer interval = less accurate recall. At 3 seconds 80%
remembered, 18 seconds 10% remembered
Conclusions - STM has limited duration of about 18 seconds. No
rehearsal = not passed to LTM, supporting the MSM
What are the strengths of Peterson & Peterson VERIFIED ANSWER -
lab study, highly controlled and therefore has high validity
What are the weaknesses of Peterson & Peterson VERIFIED ANSWER
- poor sample - used only American uni students, may have encountered
