Module 6 Flashcards
What is split brain
A surgery that cuts the axon between the two hemispheres (corpus callosum)
Why would someone have split brain surgery? What are the consequences?
To stop seizure. The hemispheres can no longer communicate (perception, language)
What side of the body starts acting on it’s own when the hemispheres are split?
the left
what is hemispheric specialization?
The idea that each hemisphere has separate functions
if the left visual field is shown an image in a split brain person would they be able to tell you what the image is?
No. The left side of the brain process language
What does denett’s video teach
consciousness is the result of several processes in the brain that can operate independently and interact with one another depending on what the task demands.
define consciousness content
subjective experience of internal and external world
define state of consciousness
refers to different levels of arousal and attention
define attention
the process of selecting information from the internal and external environments to prioritize for processing.
when you hear a loud noise in a quiet room, it is likely that you will immediately stop what you are doing and search for the source of the noise. What is this called
a. attention
b. passive attention
c. active attention
b. passive attention
what is active attention?
when attention is directed by goals and top-down processing
define selective attention.
occurs when you attend to one source of information while simultaneously ignoring other stimuli.
define stimulus salience
some stimuli capture attention due to physical properties (bright light in dim room, loud noise in quiet room)
when your attention is diverted from a salience of a stimulus this is called
A. SELECTIVE ATTENTION
B. ATTENTION DEFIANCE
C. ATTENTIONAL CAPTURE
C. ATTENTIONAL CAPTURE
What is the cocktail party effect?
an example of selective attention. a situation in where an individual suppresses other stimuli in an active environment to pay attention to the conversation
when a person is simultaneously doing two tasks at once this is known as
divided attention
automaticity is a type of
divided attention
define inattentional blindness
tendency to miss changes when attention is engaged elsewhere
what was Cortney and woods experiment?
City names and electrical shock
Experiments that use the flicker task are known as
intentional change detection
what is inhibition
the act of your brain zoning out other information to focus on a specific task
what is a subliminal stimuli
a sensory stimulus that is processed but does not reach the threshold for conscious perception
French music played in a liquor store, people were more likely to purchase French wine than German wine; however, if the music in the store was recognizably German, patrons purchased German wine more often. What type of processing is occuring
a. internal processing
b. external processing
c. subconscious processing
d. subliminal processing
c. subconscious processing
subliminal processing vs subconscious process
things that cannot be picked up quickly enough to process vs stimulus that affect our actions without noticing
difference between inattentional blindness and change blindness
Inattentional blindness – not change blindness – explains a person’s failure to notice it because the average person is not actively looking for it. (If you were actively looking for it and still missed it, this would be change blindness instead).
