CONCLUSIONS - BRAIN, MIND AND BEHAVIOUR (Human Behaviour and How The Mind Works)
INSTINCTS AND INSTINCTIVE BEHAVIOUR
We saw that instincts are an innate form of behaviour, that is a form of behaviour
which is not learned but which the animal performs from birth, without being trained
to do so.
Behaviour relating to survival of a species, such as attack, defence and sexual
behaviour, is instinctive and responses are automatic. Territory is acquired by
force and defended. Might is right.
CONSCIOUS BEHAVIOUR: LEARNING AND EVALUATING, MEMORY AND MEMORISING
As mammals evolved from reptiles, there evolved the ability for storing new experiences
as they happen and so creating a store of experience-based memories.
A primitive animal`s memory seems to be largely procedural. Both procedural and
declarative memories are long-term memories, but declarative memory is located and
used in a different way.
Human beings are learning all the time, memorising information and then recalling
it when it is required.
What is being memorised includes what we are taught, what happens to us and to
others and any lessons learned as a result. And when it happened and the sequence
in which it happened. Including also the meaning of words and what is implied. And
in addition we have the vast mass of externally prepared and stored information
which is accumulating at an accelerating pace.
Massive volumes of information are being received. The incoming information is
evaluated and we memorise only information which seems to matter. Some is retained,
the rest rejected. Retained short-term (working) memories are converted to long-term
memories. So only a part of the incoming information is retained and stored, that
is memorised, so becoming available for recalling later when required.
Aspects of memories <9> are stored in different locations. Aspects such as colour,
shape, event, phrase, place, time, date. Aspects like shape of face, sound of voice,
colour of hair.
Memories are associated, crossindexed if you like, with their different aspects
and can be recalled by recalling an aspect associated with the memory one wishes
to recall. Component memories are continually being associated with other old or
new component memories, enormously increasing the range and flexibility of what
can be recalled.
A process which continually keeps available memory components which relate to
those of current interest, and memory components which are more frequently used
than others.
Human beings store memories by means of changed neural pathways, by means of
persistent modifications to the structure of neurons and their synaptic connections,
by means of biochemical changes.
So we are strengthening neural pathways or associations by frequently using or
recalling them, weakening memory components which are not being used.
Hence using neural pathways holds memories at higher, more easily accessible
levels of memory, makes them more readily available. Infrequently recalled memories
would seem to be overlaid by more frequently used ones, seem to be reduced to lower
levels of awareness, of accessibility.
