Psychology chapter 8 - memory Flashcards
sensoric memory is divededinto 2
1) iconic memory
2) echoic memory
Iconic memory is when
There is a brief visual presentation
Hold the memory really short
Memory is a process that allows us to
Record, store and retrieve
Experiences & information
Variable response delay in iconic memory
When you have to wait longer in between the visual cue and recall
–> recall is more difficult
Other word for short term memory
Working memory
- Because we work with the memory
- It is not only for storage
Phonological loop (working memory)
Rehearse in brain without voculizing
Store and articulate/repeat what we hear
- Makkelijk interfereable
Visual spatial sketchpad
Ability to temporarily hold visual and spatial info
Episodic buffer
Combines information from loop, visual sketchpad and long-term memory to create coherent episode
Central executive
Flexible system responsible for control and regulation of cognitive processes
Controls our action
The consolidaiton hypothesis (long-term memory) states that
Repetition trough time is enough for info to stay in long term memory
Levels of processing hypothesis (long term memory) states that
You need maintenance reheasel and elaborative rehearsal for info to stay in long term memory
Mnemonic is a strategy to
effectvely remember things
Retrograde amnesia (retro = backwards)
Loss of memory prior to an accident/stroke
Anterograde amnesia (forward)
Unable to make new memory/learn new things.
Because of lesion in hippocampys
amnesia (memory lose) is due to damage to
hippocampus
parkinson is due to damag to
substantia nigra
Substantia nigra (uitleg NL)
‘zwarte substantie”
Groep neuronen, die onderdeel vormen van de basale ganglia
infentile amnesia
No memory before 3 y/o
Sperling (A scientist)
Test iconic memory capacity and duration
Letter experiment
- Shows we record all letter
- But we lose some
- When you are told to focus on a few you will better memorize them
2 limitations of the working memory
- Interference of speech
- Limited size
Declarative memory (includes two subcategories) is
involves factual knowledge, demonstrates this
Episodic memory (subtype of declarative memory)
Store of knowledge concerning personal experiences
- when, where, and what happened in the episodes of our lives. Your recollections of childhood friends, a favourite film, and what you ate this morning represent episodic
memories.
Semantic memory (subtype of declarative)
Represents general factual knowlegde, about the world, language, memory for words and concepts
You know that Mount Everest
is the world’s tallest peak and that e = mc”.
Explicit memory (LTM)
involves conscious or intentional memory retrieval, as when you consciously recognize
or recall something.
