Hemispheric Dominance and non-verbal communication. pg. 11-14 Flashcards
Hemipheres
psychologists have suggested that the way we take in information depends on how out brain works. Right or left?
Left hemisphere
- mathematical
- words, concepts
- deductive reasoning
- precise though
- logical
- conscious
Right hemisphere
- artistic
- images, sounds
- inductive reasoning
- abstract though
- analogical, intuitive
- unconscious
corpus callsum
a narrow bridge between the hemispheres that mediates them.
deductive logic
of which symbolic logic is clear.
operates by beginning with established truths and deriving particular applications from them. (example : syllogism)
syllogism
a logical argument in which a conclusion is derived from two or more propositions.
A. All men are mortal
B. Bob is a man
C. Bob is therefore mortal.
inductive reasoning (right brain)
we don’t begin with truths, we tease them out. We sit with things that we perceive and know, and out of all of the given information, patterns begin to emerge. (example: Grounded theory)
grounded theory
resisting the urge to begin with a hypothesis, researchers will sit with collected data until they start to see connections between them, labeling those discoveries and group them into concepts and categories until they finally arrive at a theory.
Precision vs. abstraction
- left brain thinkers like their facts, as they can be handled, demonstrated and organized.
- right brain thinks like abstraction.
Psychotropic drugs
- drugs act on the central nervous system to alter consciousness, mood, cognition, perception and behaviours
- can enhance creativity (right), but can impair cognition. The enhancement of the right can cost the left.
how much of communication has to do with non-verbal?
93% of communication as to do with non-verbal
Glossophobia
the fear of public speaking. It is part of the brain that stirs in us the fight-or-flight responses.
symptoms of anxiety
-sweaty palms, increase heart rate, shallow breathing, loss of words.
