PSY 322 Exam 2 Questions with 100%
Correct Answers
Memory Correct Answer: processes involved in retaining, retrieving, and using
information about stimuli, images, events, ideas, and skills after the original
information is no longer present
- Active any time some past experience has an impact on how you think or
behave now or in the future
Modal Model of Memory (Atkinson & Shiffrin) Memory types: Sensory memory
Correct Answer: - Sensory memory: initial stage that holds all incoming
information for seconds or fractions of a second
sensory --> short-term --> long-term
Modal Model of Memory (Atkinson & Shiffrin) Memory types: short-term memory
Correct Answer: - Short-term memory: holds five to seven items for about 15 to
20 seconds
Modal Model of Memory (Atkinson & Shiffrin) Memory types: long-term memory
Correct Answer: - Long-term memory: can hold a large amount of information
for years or even decades
Modal Model of Memory: Control processes Correct Answer: active processes
that can be controlled by the person
- Rehearsal
- Strategies used to make a stimulus more memorable
,- Strategies of attention that help you focus on specific stimuli
sensory memory Correct Answer: - retention, for brief periods, of the effects of
sensory stimulation
- information decays very quickly
persistence if vision (sensory memory) Correct Answer: - retention of the
perception of light
- trail of light from a moving sparkler
- frame in film
Measuring the capacity and duration of sensory memory (Sperling, 1960)
(sensory memory) Correct Answer: - array of letters flashed quickly on a screen
- participants asked to report as many as possible
whole report method (sensory memory) Correct Answer: subjects were asked to
report as many letters as possible from the entire 12-letter display
- average 4.5 out of 12 letters (37.5%)
partial report method (sensory memory) Correct Answer: participants heard
tone that told them which row or letters to report
- average 3.3 out of 4 letters (82%)
- participants could report any of the rows
delayed partial report method (sensory memory) Correct Answer: - presentation
of tone delayed for a fraction of a second after the letters were extinguished
, - performances decreases rapidly
Results of Sperlings partial report experiments (sensory memory) Correct Answer:
the decrease in performance is due to the rapid decay of iconic memory
iconic memory (sensory memory) Correct Answer: very brief memory for things
we see
- responsible for persistence of bision
- 250-500 ms
echoic memory (sensory memory) Correct Answer: - brief sensory memory of the
things that we hear
- responsible for persistence of sound
- 2-4 seconds
short-term memory Correct Answer: - stores small amounts of information for a
brief duration
- includes both new information received from the sensory stores and
information recalled from long-term memory
Measuring the duration of short-term memory Correct Answer: -read three
letters, then a 3 digit number
-begin counting backward by threes
-after a set time, recall three letters
- after 3 seconds of counting, participants performed at 80%
