26
ATSI ways of knowing
Connected to landscape, relational, reciprocal, spiritual and based on deep connection to ancestral knowledge, holistic and traditionally transmitted orally
27
System of knowledge

28
2 common ways knowledge is patterned on country
Through kinship relationships Through knowledge being encoded in the landscape
29
Memory definition
The set of psychobiological systems and processes that allow our past experiences to inform how we respond to and interpret our current experiences and to imagine the future
30
Sensory memory
Holds sensory information in its raw form for very short periods of time
31
STM
An active store that holds all information you are consciously aware of at any moment
32
LTM
A relatively permanent, limitless passive storage system
33
Strength of the multi store model of memory
Its ability to explain how information is transferred from LTM to sensory memory and STM, and why forgetting occurs. Demonstrated through the serial position effect
34
Limitations of the multi store model
-Does not explain the different forms of LTM that were so apparent in the case of HM -Does not explain how we encode, store and retrieve information about the events of our lives, how we organise our knowledge of concepts and words, or how we learn and perform skills -Fails to explain why some forms of memory are affected by hippocampus damage and some are not
35
Explicit memory
Consciously recalled memories of facts or personally experienced events
36
Semantic memory
Memories of general facts or concepts, including self-related knowledge
37
Episodic memory

38
Implicit memory
Unconscious recall of memories of how to do something
39
Procedural memories
Memory of learnt skills and actions
40
Hippocampus
Encodes/retrieves explicit memories, interacts with the amygdala to link emotions with explicit memories and interacts with the neocortex to store and retrieve explicit memories
41
Amygdala
Emotional memories, plays a role in the rapid and unconscious processing of emotions (implicit) and feeds this information to the hippocampus to be integrated into explicit memories
42
Neocortex
Stores explicit memories, our explicit LTMs are stores in the networks of neurons in the neocortex
43
Basal ganglia

46
Episodic autobiographical memory

47
Autobiographical memory

49
Mental imagery
Perception like experiences in the absence of sensory input,
50
Alzheimers disease
A neurodegenerative disease that causes a progressive loss of brain tissue (atrophy) that is eventually fatal.
51
Biological causes of Alzheimers disease
-Abnormal build up of beta-amyloid, which collects into clumps called amyloid plaques, that build up between neurons and affect their functioning -Build up of tau protein causes neurofibrillary tangles that interrupt cell transmission -Brain atrophy, neurons progressively die causing brain tissue to shrink
52
Progression of Alzheimer's disease symptoms
-Severe anterograde amnesia for EAM and semantic memories (memories about new recent events and facts learned at these events) Also difficulty generating voluntary mental imagery and episodic future thinking -Retrograde amnesia for EAM -Loss of general semantic knowledge -Procedural memory

68
Reproducibility
The closeness of results of measurements/tests, carried out under changed conditions
69
Validity
How well do the results represent true findings among the population of interest?
70
Internal validity
Did the experiment investigate what it set out to investigate? Depends on sampling, design, EVs and confounding variables
71
External validity
Can the results be applied to similar individuals in a different setting/the real world? Depends on the sample representing the population and using measures that reflect the real world.
72
Uncertainty
The lack of exact knowledge of the true value of the measurement.
73

94
Phobia
A form of anxiety disorder where a person experiences an intense, irrational and out of proportion fear of a specific object, activity or situation
95
LTP contribution to specific phobia
LTP occurs in the cells of the hippocampus, producing neural changes that underlie the formation of memory. When we associate fear with a specific stimulus, a new memory circuit with connections within the amygdala is thought to be made through LTP.
96
Cognitive bias
An automatic tendency to process or interpret information in a particular way, producing systematic errors in thinking when making judgements or decisions.
97
Memory bias
The tendency to remember information of one kind at the expense of another kind, including the bias towards remembering negative and threat related experiences associated with phobia.
