KKDP6 - imagined futures, Alzheimers, and Aphantasia Flashcards
(20 cards)
AUTOBIOGRAPHICAL MEMORY:
- a person’s memories of their own life
involves:
episodic memory e.g. personal experiences at a particular time or event
semantic memory e.g. self- factual memories - mix of the 2
e.g. meeting the teacher is episodic
learning the teacher is semantic
IMAGINED FUTURES?
- hypothetical experiences and situations made based on past experiences & memories
- episodic future thinking: simulation of personal future
- affective forecasting (prediction of future feelings)
RECONSTRUCTION
- when retrieving autobiographical memory
- use reconstruct
- available info to form a more coherent and accurate memory
NEURODEGENERATIVE DISEASE?
- group of progressive neurological disorders
- destroys cells that control our essential muscle activity
e.g. walking, breathing and swallowing - impact on cognitive skills
e.g. alzheimer disease
WHAT IS ALZHEIMER DISEASE?
- irreversible, progressive brain disease
- slowly destroys memory and thinking skills
- eventually even the ability to carry our simplest task
CHANGES IN THE BRAIN CAUSED BY ALZHEIMER DISEASE?
neurofibrilary tangles and amyloid plaques
WHAT IS NEUROFIBRILARY TANGLES?
- develop inside neurons
- hard fibers that inhibit effective communication between neurons
WHAT IS AMYLOID PLAQUES
- formed outside the neuron
- as they turn hard they prevent neurons from communicating
- acting like a barrier
CHANGES IN THE BRAIN CAUSED BY ALZHEIMER DISEASE? ii
- as more plaques and tangles form, neurons begin to work less efficiently
- lose ability to function & communicate, &eventually die
- begins in HC then spreads
WHAT CAUSES ALZHEIMER DISEASE?
complex series of events that take place in the brain for a period of time
e.g. genetics, environmental factors, lifestyle factors
ALZHEIMER DISEASE RISK FACTORS?
- risk of developing AD when you age
- close blood relative can increase your risk
- combination of genes for proteins
DIAGNOSIS OF AD?
doctors:
- ask questions about the person’s overall health, past medical problems, ability to carry out daily act and changes or behavior/personality
- conducts tests of memory, problem solving, etc
- carries out medical tests e.g. blood, urine
- perform brain scans, CT OR MRI
PROGNOSIS OF AD?
- as the disease develop the individual will notice more persistent and frequent memory lapses
- forgetful
- later stages they’ll require 24-h care
- no cure
PHYSIOLOGICAL V PSYCHOLOGICAL OF AD?
- alzheimer is a physiological disease
resulting to psychological factors e.g. memory loss, changes in personality
APHANTASIA?
- inability to visualize imagery
- not a disability
- struggle to remember or ‘relive’ autobiographical memories
- difficulties imaging future or hypothetical events
2 FORMS OF APHANTASIA?
congenital: have never experienced visual mental imagery, from birth, no cure
acquired: develops after a brain injury, trauma, person who used to have visual imagery but lost it
AMNESIA?
a form of memory loss that affects a pesons ability to store, retain, or recall info.
- it can be permanent o temporary
WHAT IS REQUIRED TO OBTAIN INFO FROM A PARTICIPANT WITH ALZHEIMER DISEASE?
- capacity to make an informed decision
- informed cnsent must be obtained by a legal guardian/career
- researcher must frequently ‘check in’ with the participant thoughout the study to ensue there capacity to make decision has changed
WHAT MEMOIES ARE MOSTIMPACTED IN THE EARLY STAGES OF ALZHEIMERS?
- explicit memoies
= bcs hippocampus which is necessary for encoding of explicit memoies appear to be the first brain area affected by alzheimer
DOUBLE BLIND PROCEDURE?
A double-blind procedure is when both the participants and the researchers who interact with them (or collect data) do not know which condition/group the participants are in.
