Exam 1 Flashcards
What are the five types of research?
Case studies, naturalistic observation, surveys, archival research and longitudinal/cross-sectional
What are the 4 steps of the scientific method?
Theory, hypothesis, research, observation
Describe how theories and hypotheses are different
Hypotheses are testable predictions and theories are overarching constructs
What surprising thing could the blind patient do? Which pathways did she use to do this?
She could use “blind sight”. Using the “where” pathways in the brain she could detect objects but could not see them consciously because of issues with her “what” pathway
What does blind sight and loss of color vision demonstrate about vision?
It demonstrates that vision is composed of multiple areas of the brain working together to create one conscious image we see
What does blind sight illustrate about other parts of the brain?
Blind sight illustrates that senses and perhaps other functions of the brain are composed of multiple subcomponents working together.
What does Ramachandran say the example of blind sight tell us about the self?
He says that blind sight demonstrates that there is not a single “I” within us because we have many automated processes working without our awareness to create the sensation of a single
“I”
What is Anosognosia?
It is the disorder of being unaware of illness through denial of symptoms.
What do less extreme patients with anosognosia do to avoid confronting reality?
They come up with rationalizations as to why they can’t do things. Like being tired or not wanting to do it.
What behaviors does Ramachandra believe normal people share with Anosognosia patients
He believes that normal people also have psychological defense mechanisms that prevent them from dealing honestly with reality
What is the Freudian view of anosognosia?
The Freudian view is that the patient does not want to confront the unpleasantness of their paralysis
What is the neurological view of anosognosia?
The neurological view is that it is the consequence of neglect syndrome which occurs when there is damage to the right hemisphere and leaves the patient indifferent to the left side of their body
What are the two problems with Freudian explanations of anosognosia?
- It does not explain the difference in magnitude of defense mechanisms between normal people and anosognosia patients
- It doesn’t explain the asymmetry of anosognosia almost always being associated with the right side of the brain
What are the two problems with the Neurological view of anosognosia?
- Neglect syndrome does not account for continued denial of the paralysis even after the patient is made aware of it.
- Neglect syndrome and denial both can occur independently of each other.
What does Ramachandran say are the functions of the left and right hemispheres?
Right hemisphere- functions in understanding metaphor, allegory, and ambiguity
Left hemisphere- functions in producing speech, language syntax, and semantics
