Module 8: Brain States and Consciousness
8.1- What is the place of consciousness in psychology’s history?
There was a period of time where psychology lost consciousness and was
dened as the science of behavior
Around 1960s, mental concepts reemerged. Neuroscience advanced linked
brain activities to sleep, dreaming and other mental states.
Researchers began to research about the mental aspect of human being, they
began to study consciousness altered by hypnosis, drugs, and meditation.
Hypnosis: state of consciousness in which a person apparently loses the
power of voluntary action and is highly responsive to suggestion or direction.
Its use in therapy, typically to recover suppressed memories or to allow
modication of behavior by suggestion, has been revived but is still
controversial.
Psychologist began to put more importance toward cognition, or mental
processes. Today, they dene consciousness as our awareness of ourselves
and our environment. This awareness allows us to assemble information from
many sources as we re*ect on our past and plan for our future. It focusses
our attention when we learn complex concepts or behavior.
Cognition:
Di/erent state of consciousness:
In addition to normal, waking awareness, consciousness comes to us in
altered state, including daydreaming, drug- induced hallucinating and
meditating.
Some states occur spontaneously: Daydreaming, drowsiness, dreaming
Some are physiologically induced: Hallucinations, orgasm, food or
oxygen starvation
Some are psychologically induced: Sensory deprived, Hypnosis,
Meditation
Altered State of Consciousness (ASC): also called altered state of mind
or mind alteration, is any condition which is signicantly di/erent from a
normal waking beta wave state.
What does Evolutionary Psychologist think about consciousness?
They think that consciousness o/ers a reproductive advantage. It helps us
cope with situation and act in our long term interests, rather than merely
seeking short-term pleasure and avoiding pain. Consciousness also promotes
our survival by anticipating how we seem to others and helping us read their
mind: “he looks really ugly! I’d better run
