Memory & Cognition Flashcards
Inattentional Blindness
failure to see something we’re looking at, occurs because attention is preoccupied
Visual Pop-Out
idea that some basic features don’t need attention to be seen
- “primitive” features would naturally stand out
Feature Integration Theory - Anne Treisman
when perceiving a stimulus,
- features are “registered early, automatically, and in parallel,
- while objects are identified separately” and at a later stage in processing.
attention serves to bind simple features together, the binding process is slow and serial
Spatial Attention
selecting chunks of areas as a means of searching for an item
Change Blindness
bad at noticing even large changes and a failure to update representations between views
Feature Based Attention
prioritizes the processing of non-spatial features across the visual field, processing of entire visual field as opposed to select chunks
for example someone wearing a bright colour shirt will stand out in visual field
Memory Athletes don’t
- score higher on general cognitive ability
- have a larger hippocampus
instead fMRI showed that they used different brain areas, often involved in visual imagery and spatial navigation and they use encoding strategies
encoding
how information is put into the mind
retrieving
how information is pulled out of the mind
Multi-Store Model of Memory
Atkinson & Shiffrin, 1998
input –> sensory memory
–> short-term memory (working) –> long term memory
short to long term memory = consolidation
long to short term memory = retrieval
sensory to short term memory = attention
sensory memory
“iconic memory”
richly detailed visual memory that persists for a fraction of a second
working memory
short-term memory
- information is consciously focussed with attention
Memory Palace Method
connect images to subjects, placed along a path and then repeat process
Chess Configurations - Chase & Simon, 1973
- child experts used chunking to understand the pieces of information better than adult novices despite the adults larger memories
meaning is imposed on the subjects of memorisation
schema
knowledge or expectations about a domain or event, structuring information in the mind
The Deese/Roediger-McDermott Effect
memory can be distorted by our biases and assumptions and by misleading information
–> by our schemas
The War of The Ghosts - Frederic Bartlett (1932)
suggested that recollections become increasingly shaped by our schemas as detailed memories fade
Elizabeth Loftus & Palmer, 1974 - False Memories
the way the question is asked can alter the answers or interpretations of the event, information gained about event after it occurs may inform what you think has happened
- Creation of the Cognitive Interview
1. Mentally reinstate context
2. Report everything, even extraneous details
for example
- how hard did the car hit you?
- vs
- how hard did the car smash into you?
Source Monitoring includes
keeping track of where memories come from
external source, internal source, reality monitoring
internal and external source monitoring
External: distinguishing information retrieved from external sources, “what i thought vs what they thought”
Internal: distinguishing information retrieved from, “what i thought vs what i said”
Recognition
Recognition: identifying something as familiar to a previous experience
desirable difficulties
bjork & bjork 2011
challenges that may seem to slow down learning and performance, but which lead to longer and better memory
include:
retrieval practice, spaced practice, elaboration (deep encoding)
retrieval practice
practicing recalling information
- can result in retrieval failure
- done by re-studying for higher retention
retrieval failure
failing to retrieve something
some types include:
- blocking: the feeling of there being something interfering with access to memory, even though the memories are intact and well-encoded
- tip-of-the-tongue phenomenon: the feeling of not being able to bring a word to mind despite being able to recall things associated to it
spaced practice
as opposed to massed practice
consolidation: the stabilisation of memories that have already been encoded, spread out over time
elaboration (deep encoding)
link parts of material to each other and to your own interests, generate new examples, force engagement with deeper meaning
actively forming mental links
Why may emotions relate to memory?
amygdala and hippocampus are in close proximity
