-
processes by which information is encoded, stored, andretrieved.
Memory
-
Information about the outside world reaches our senses in the form of physicaland chemical stimuli
Encoding
-
remembering things as a picture.
Visual code:
-
remembering things as a sequence of sounds
Acoustic code:
-
remembering things in terms of their meaning
Semantic code:
-
maintaining information over time
Storage:
-
mentally repeating information.
Maintenance rehearsal:
-
our awareness of the functioning of our memory.
Metamemory:
-
elaborating or extending the semantic meaning ofwhat you are trying to remember
Elaborative rehearsal
-
requires locating stored information and returning it to consciousness.
Retrieval
-
three stages of memory
- Sensory memory
- Short-term memory
- Long-term memory
-
is the type of memory that is first encountered by a stimulus.
Sensory Memory
-
Visual stimuli are referred to as
icons
-
The sensory register that holds icons
iconic memory
-
Photographic memory is technically referred to as
eidetic imagery
-
having the ability to store visual stimuli for remarkably long periods of time.
Eidetic imagery
-
occur about four times every second.
Saccadic eye movements
-
Iconic memory holds icons for up to
a second
-
Mental representations of sounds, or auditory stimuli, are called
echoes
-
The sensory register that holds echoes
echoic memory
-
If one focuses on a stimulus in the sensory register, they will tend to retain it in _________
short-term memory
-
also referred to as working memory
short-term memory
-
In short term memory the image tends to significantly fade after if it is not rehearsed.
10-12 seconds
-
The tendency to recall the first and last items in a series
serial-position effect
-
discrete elements of information
Chunking:
-
the third stage of information processing
Long-term memory
-
memories people tend to remember that are surprising, important, and emotionally stirring
flashbulb memories
-
arrangement of items into groups or classes according to common or distinct features.
hierarchy
-
the feeling of knowing experience.
tip-of-the-tongue-phenomenon
-
clear in the context in which they were formed.
Context-dependent memories
-
We retrieve information better when we are in the physiological or emotional state that is similar to the one in which we encoded and stored the information
State-Dependent Memory
-
Three basic memory tasks have been used to measure forgetting:
- Recognition
- Recall
- Re-learning
-
Failure to recognize something we have experienced
Recognition
-
Remembering information from memory without cues.
Recall
-
We can relearn information more rapidly the second time.
Relearning
-
difference between the number of repetitions needed to learn and the number of repetitions to relearn the list.
savings
-
new learning interferes with the retrieval of old learning
Retroactive interference
-
older learning interferes with the capacity to retrieve more recently learned material
Proactive interference
-
we are motivated to forget painful memories because they produce anxiety, guilt, and shame
Repression
-
recovered memories that are sometime induced by therapists
pseudomemories
-
difficulty in remembering episodes that happened prior to age 3 or so
Infantile amnesia
-
memory lapses for the period following a trauma.
Anterograde amnesia
-
memory lapses for the period before the accident
Retrograde amnesia
-
electrical circuits in the brain that correspond to memory traces.
Engrams
-
increases the efficiency of conditioning.
Serotonin
-
released when stimuli are paired repeatedly.
Serotonin
-
involved in the formation of new memories
Hippocampus
-
Parts of memories are stored in appropriate areas of the
sensory cortex
-
largely responsible for integrating these pieces of information when we recall an event.
limbic system
-
acts apparently as the executive center in memory
prefrontal cortex
-
involved in verbal memories.
Thalamus
