two types of long term memory
implicit and explicit
explicit memories
a type of long term memory that can conciously/ volunatrily retrieved and brought into concious awareness, they can be declared or stated to someone else
explicit memory aka
declarative memory
types of explicit memory
semantic memory and episodic memory
semantic memory
consists if general knowledge or facts, they are declaritive in that they can be verbally explained to others
episodic memory
consists of personal experiences or events, memories are unique to each individual and their own personal experiences
how are explicit memories recalled holistically
remeber many different aspects of the situation such as the day, time, place and other people that were there
examples of semantic memory
there are seven continents, dogs bark, 3x3=9
examples of episodic memories
getting your drivers licence, what you ate for dinner last night
implicit memory
type of long term memory that is unconciously/involuntarily retrieved, the memory is how to do something and is retrieved without concious effort
two types of implicit memories
procedural memory and classically conditioned memory
procedural memory
involves knowing how to carry out tasks that are facilitated by motor skills
classically conditioned memory
involves an involuntary response, such as fear, to a stimulus which has repeadtly been associated with an emotionally-arousing stimulus. this response is usually emotionally charged involving strong feelings, or an involuntary habit
examples of classically conditioned memory
biting nails in a nerve racking situation (involuntary habit)
examples of procedural memories
how to tie your showlaces, kick a ball
what is the relationship between brain structures and memory
memory is not a single process that occurs in one region of the brain, it requires the interaction between various brain structures
what are the brain stuctures involved in long term memory
hippocampus, amygdala, basal ganglia, neocortex and the cerebellum
location of the hippocampus
located in the temporal lobe, with one in each hemisphere deep within the brain
hippocampus role in LTM
formation, consolidation and encoding or explicit (semantic and episodic) memories
what causes damage to the hippocampus unintentionally
stress, anxiety, depression, PTSD, brain trauma, disease (e.g alzeimers or herpes virus) can shrink it
why is the amygdala untentionally damaged or removed
as treatment for epilepdy
what is the affect of damage to the hippocampus
individuals will experience difficulty forming new long term explicit memories
location of amygdala
small ball located just above/on the end of the hippocampus in the temporal lobe
role of the amygdala
described as the fear centre, responsible for encoding and strengthening the emotional components of classically conditioned and explicit memories, contributes to these memories being encoded in greater detail
