11 - Consciousness Flashcards
Dualism
mind and brain are two different things
mind exists independently of the brain
idealist
mind controls the body
only mental phenomena exist
physicalist
mind arises from the brain
for every mental event there is corresponding brain event
what does neuromorphic mean
used to describe analog, digital, and mixed-mode analog/digital VLSI and software systems that implement models of neural systems (for perception, motor control, or multisensory integration)
neuromorphic computing
the use of very-large-scale integration (VSLI) systems containing electronic analog circuits to mimic neuro-biological architectures present in the nervous system
what is a motor neuroprosthetic device
Brain Computer Interface
a device that can moniter and decode the electrical language of the user’s thoughts and convert that information into some tyoe of overt machine control
what is conscious content
info we’re aware of at any given moment
characterised by the experience of perceptions, thoughts, feelings, awareness of the external world and self-awareness
what is the conscious level
state of consciousness
from coma through to alert wakefulness
what is phenomenal consciousness
feelings, sensation and orienting to the present moment
what is access consciousness
ability to reason, to reflect, to have a sense of self, that extend beyond the current moment
5 functions of consciousness
associated with perceiving the environment
crucial role in social communication
role in controlling our actions
allows us to think about events and issues far removed from the present
integrating and combining numerous types of information
what junction is essential for self-awareness
temporo-parietal junction
(Aarts & van den Bos) and (Wegner)’s two definitions of free will
the ability to make choices and to determine one’s own outcome free from constraints
free will is an illusion. our actions are caused by unconscious process
2 brain regions associated with consciouness
anterior cingulate cortex (ACC)
dorsolateral prefrontal cortex (DLPFC)
strengths of global workspace theory
all major assumptions have been supported
early processing of seen and unseen stimuli is similar
consciousness is associated with integrated brain activity including PFC & ACC
close links between attention and conscious awareness
