Quiz 1 Flashcards
Descartes Dualism
Distinguished between conscious god-like thoughts (originated from god) and unconscious animal thought. Also distinguished between the mind and the body
Mesmer - Animal magnetism - 1770 and hypnosis 1840
used arm movements to change the magnetic fields of patients and used hypnosis to change the minds of the subject without the subjects awareness
Darwin - Animal breeding
Farmers have unconsciously been using the principles of natural selection to beef better cops and livestock
Séances and spiritualism - 1800
Belief in what might happen is influencing their behaviour which gives an unintended result
Ex: Ouija boards
Sigmund Freud - Hysteria and neurosis 1900
Made the metaphysical physical by putting the illness inside the brain as a part of their unconscious mind. Thought unconscious was a filter for conscious thought
Watson - Behaviourism 1913
People motivated by rewards and punishment. No reliable methods to study the mind so Watson and other behaviourists concluded that the mind was not causal and that conscious thoughts were not behaviour
Skinner - Verbal Behaviour
Verbal behaviour and other higher mental processes are environmentally driven by stimulus-response linkages
Cognitive Revolution - 1960’s
Complete reversal of role of environment in determining higher mental processes
Behaviourism - 1957
Environmental control over behaviour means there is no role for consciousness or for cognitive processes
Neisser - pre attention analysis, pattern recognition, figurative synthesis (cognitive revolution)
Replaced external stimuli as the cause of behaviour with goals and executive processes
Left a causal vacuum because her research basically said consciousness was used for everything
Crude products furnished to our conscious executive processes
Anne Triesman - attention
Attention changes peoples experiences; intention changes behaviour
Dawkins - selfish gene/“unconscious watchmaker”
Not your mind that runs your consciousness it’s your genes, all bodily functions are governed by your genes. Goal of your genes is to survive and reproduce
The role of technology
Helped propel the cognitive revolution by the creation of things like stereo headphones and tachistoscope
Helped physiologists such as triesman and broadbent
Unconscious
The processing of information without our awareness and sometimes without our intention
What came first conscious or unconscious mind?
Unconscious mind
Rozin - Conscious access to evolved unconscious mechanisms 1976
Learning and education bring consciousness to limited-access programs in our unconscious
Reber- what came first?
Unconscious mind evolved first and predates the conscious mind
Loftus & Klinger - is the unconscious smart?
Unconscious mind is not as smart as Freud made it out to be. It is easily influenced by subliminal messages and lack of awareness of the causes and consequences of those messages and external stimuli on our mental processes
Nesbit & Wilson - justification of primes
Can’t always rely on individuals personal account. People justified primed unconscious behaviour which confirms that we don’t know why a prime changed our behaviour in the first place
What’s the cost for conscious thought?
Conscious thought requires 20% of our total energy use even though the brain is only 2% of total body mass
William James quote
Consciousness drops out of any process where it is no longer needed
Ex: Driving a car
George Miller - “magical number 7 plus or minus 2
Showed that there are limits to the amount of information we can keep in our working memory at one time
Wilson et al - conscious thought is painful
Participants would rather subject themselves repeatedly to a painful shock than be alone with their thoughts
W. James -behavioural impulse
Consciousness is not a source of behavioural impulses, more like a gatekeeper having veto power
Gazzinga - impulse understanding
Impulses from the right hemisphere are understood narrative-like by the left hemisphere
Libet - impulses
Impulses come from before conscious awareness of them
Wegner - impulses
Conscious agency (source of impulses) an illusion produced by attributional deduction; no true conscious causation for impulses
Conscious vs unconscious (definitions)
Conscious: awareness, intentional, slow/serial, controllability
Unconscious: unaware, unintended, fast/parallel, uncontrollable
Two different forms of not conscious
Subconscious (skill acquisition) intentional and efficient procedural learning
Preconscious processing: unintentional, immediate, and unaware analysis of stimuli
Jastow - skill acquisition
Argued that for processes to transition from conscious to unconscious required experience
Ex: driving a car
Reversed Freud’s notion of relationship between conscious and unconscious
Schiffin & Schneider - attention vs automatic processing
Used varied and consistent mapping to study attention vs automatic processing. Participants gradually became unaware of rehearsal or attention-demanding controlled processing after 600 trials.
External stimuli activate internal representations which they’ve become automatically associated with
Varied mapping
Sometimes the item (category) is the target, sometime it is the distractor
Controlled serial search (much slower)
Consistent mapping
Item(category) is either a target or a distractor and they don’t change
Automatic detection
Bargh & Ferguson - environmental stimuli
Environmental stimuli can trigger higher mental processes if cognitive processing is allowed to mediate these effects. Social behaviour in the external environment often access their corresponding mental representations in an immediate and direct manner without consciousness.
Mechanic can’t fix a car without looking under the hood
Subconscious processing
Same as skill acquisition: intentional and efficient, procedural learning
Bruner & Postum - preconscious analysis
Preconscious analysis of meaning prior to the perception of the stimulus. Filtered the world before stimulus was consciously perceived. Used a tachistoscope
Anne Triesmann - cognitive revolution
If there is some analysis of meaning prior to our perception of the stimulus this would mean that there is an unconscious, unintended analysis of the world and then the products of that analysis are furnished to conscious awareness
Tachistoscope
Displays an image for a set amount of time
Cleary - cocktail party effect
People noticed their name being said in one ear even if they were supposed to be focusing on the sounds coming into the other ear
Broadbent - filter world through physical aspects
We have control over our perceptual experiences. He was wrong about the barrier being based on physical stimulus
Triesmann - attentional barrier
Stimuli relative to our current purpose break through the attentional barrier. Participants shadowing a story played in 1 ear would automatically switch and continue shadowing when the story started playing in the other ear.
Deutch & Deutch - late selection
Every intake of information is analyzed for meaning but only what’s important is made conscious
Norman - top-down vs bottom-up processing
Preconscious analysis determined by accessibility of relative info matching internal representations
Modern Preconscious effect
Faces: trust, competence, other personality impressions (tordorov)
Stereotypes and biases
Coding behaviour (Uleman et al)
Effect of evaluation
Perceptual motor skills with a great deal of experience
Willis & tordorov - faces
Time constraint of 100 millisecond vs no time constraint had no affect on trait judgments of faces. Additional time only increased confidence
Bellew & tordorov - competence
Judgment of competence of peoples faces didn’t change with 100 ms vs 200 ms vs no time constraint
Governor races and senate races decided based on perceived competence based on the face
Perceptual fluency
We trust our senses implicitly, we trust them as true and valid information that comes to us effortlessly and fluently
Kelley Brown & Jasechko - implicit memory
Participants given list of names to memorize ten asked the next day to report who they thought was famous out ROA random list of names. Participants told that prior memorized names were NOT famous, yet still judged remembered names as famous
Fluency taken as a cue for validity or diagnosticity of the external information
