week 4: autobio memory Flashcards
autobiographical memory general definition
- events, situations, and other knowledge about yourself across your whole life
what order do people report in relation to type of info for ABMs?
general then specific
what type of memory takes longer to retrieve: ABM, SM, or EM
ABM, takes about 2-15 seconds vs other ones that take 1-2 seconds
distortion and vicarious in relation to ABM
distortion: changes happen based on other ppl’s accounts
vicarious: if you hear the story enough you can perceive it as your own (childhood memories)
methods of studying ABM
- galton-crovitz cue word method: use words as cues to generate first memory that comes to mind (ex tree)
- cue phrase for life events: ‘meeting new friends’, going to bday part etc
- diary studies: keep diary record of life events (weeks, years, months)
functions of ABM
- social: positive and other focused, serves interpersonal/ conversational function (why you chose your career)
- reflective: positive self focused attention aimed at understanding who you are (ppl get to know you)
- ruminative function: self-focused and directed at perceived losses and threats (ppl who have passed)
- generative function: aimed at positive impact on the world and create legacy (prior experience to teach others)
examples of measures of ABM (ex diaries)
- sensecam: case study w ppl w amnesia (remembered more w sense cam), camera that records activity
- hippocamera: memory prosthetic app designed at u of t, you can rate your videos, more like social media
- 1second everyday: social app where ppl record 1 sec of video every day
three levels of ABM (general)
- Event specific memories
- lifetime periods
- general events
event specific memories
- individual events
- closest to basic EM
- contains details from different modalities, features, emotions, space, time
four ways event specific memories endure
- most are lost over time but some endure like memories of:
- initial events that cause later goal related memories (experiment that directs career path)
- turning points when a person’s life plan is redirected (torn muscle)
- events that become basis for major belief system (religion)
- anomalous events that guide future behaviour (overhearing trash talk)
lifetime period ABM
- long stretches of time that are organized along common theme (ex early childhood, career)
- broad, theme based portion of person’s life
general event memories
- unifies smaller events into one memory
- sequence of events that form larger episode (ex first day on the job (all events throughout the day)
OR - repeating event (ex memory of class taken last year)
- require integration (bring dif memories together) and interpretation ( know how sub events fit together)
taxonomy of ABMs
- three categories for memory but lines can be blurred
evidence for hierarchy of ABMs
- different types of memory elicited by dif cues
- ex event specific reports cued by no specific target audience/ after hearing narrative centred on lifetime theme
- ppl w amnesia: can recall lifetime periods of general events but not specific episodes
in relation to three levels of ABM, what would someone with left hemisphere damage have intact and have trouble w
intact: general, lifetime
impaired: specific
in relation to three levels of ABM, what would someone with frontal parietal/parietal-occipital damage have intact and have trouble w
intact: N/A
impaired: all
in relation to three levels of ABM, what would someone with lrigth antierior temp. lobe damage have intact and have trouble w
intact: specific
impaired: general, lifetime
in relation to three levels of ABM, what would someone with thalamic damage have intact and have trouble w
intact: N/A
impaired: all
ABMs are life narrative memories, organized in ____ and cued by their ____
stories, elements (ie smell, sound)
ABMs elicited by smells tend to be ____
emotional, can be bc of its close proximity to amygdala
- they are also more memorable and elicit more rare memories
factors driving AMB retrieval
- clustering (causally related memories are retrieved one after another)
- common elements (shared person)
- order (fill out memories w semantic details)
- narrative structure
- snapshots are bad cues (poor memory for order of event if looking at specific)
POV of memories and age
- older memories: observer (out of body) also less emotional and more self aware
- newer: field (pov from eye view) also more emotional and less self aware
schema copy plus tag model
- when you experience a new event, you activate the appropriate schema which becomes the basis for your event memory
- reduces the need to actively think about every detail
- can assume most details abt event are as they usually are
- ppl use schemas to reconstruct incomplete memories (fill in the blanks with previous schemas)
- in short: first activate schemas as a basis then denote important schema-inconsistent details (tags)
schema
mental concept that helps people anticipate and respond to situations and experiences
