Week 8 Ch.5 Consciousness Flashcards
phenomenology
how things seem to the conscious person
Problem of other minds
the fundamental difficulty we have in perceiving the consciousness of others. How do you know that anyone else is conscious?
experience
People judge minds according to the capacity for such as the ability to feel pain, pleasure, hunger, consciousness, anger, or fear
agency
People judge minds according to the capacity for such as the ability for self-control, planning, memory, or thought
The properties of consciousness are
-unity:
-selectivity:
-transcience
-uniqueness:
-intentionality:
Minimal consciousness
A low-level kind of sensory awareness and responsiveness that occurs when the mind inputs sensations and may output behaviour
Full consciousness
A level of consciousness in which you know and are able to report your mental state.
Self-consciousness
A distinct level of consciousness in which the person’s attention is drawn to the self as an object
Electroencephalograph (EEG
the consciousness meter, a non-invasive procedure that records the electrical activity of neurons on the surplus or cerebral cortex of the brain
The 4 different brain wave patterns
Beta waves: awake and alert, intense focused thinking
alpha waves: awake and relaxed, they are a relaxed state awake but relaxed
Theta waves: are for falling asleep
Delta: are the slowest waves for deep sleep
Circadian rhythm
Is the daily cycle of 24hrs and it is the cycle all of our systems follow
Zeitgebers
(time givers in german)
Are external cues that synchronize internal clock to sloalr time when the light level increases our body becomes alert when the light levels go down the blood pressure slows melatonin releases
Clock genes
The circadian rhythm is genetically predetermined Scn or the master clock
A sleep study generally involves
Electroencephalograph (EEG) – brain activity
Electrooculograph (EOG) – eye movements
Electromyograph (EMG) – muscle tension
Neural plasticity
is sorting out which neural connection should be pruned out and what memories should stay, deep sleep is like a housecleaning stage
Night terrors
are not connected to dreaming people dont experience reporting them it a disruption of sleep is an anxiety reaction
Rem sleep
rapid eye movement
-vivid dreaming
-EEG beta waves
-Increased hr and arousal
-Immobilized muscles
-Memory consolidation, emotion processing
-20% of total sleep
Unlike in rem sleep, what part of the brain is activated in lucid dreaming?
the prefrontal cortex because of that decision-making center
theories of the Functions of sleep
Preserve and protect
It preserves energy and resources
Restore and repair
Repairs wear and tear on the body and restore energy
Learning and memory consolidation
Solidifies memory and learning
Freud’s wish fulfillment theory
They reflect symbolic wish fulfillment a window into the unconscious mind a repository of suppressed urges and desirable, like sexual or aggressive
Activation-synthesis theory
the brain created order out of chaos making meaning or stories out of incoherent random bursts
Problem-solving theory
it’s the balance between Freud and synthesis theory,
-your brain sorting out the problems of the day and the dream is how we interpret it but it’s not often the rationale
