This model is an example of a computational model and contains “demons.”
What is the pandemonium model?
100
These types of rules are a weakness of cognitive maps because while they help us quickly remember visual information, they can make things distorted.
What are heuristics?
100
In order for a neuron to fire, it must reach this.
What is a threshold?
100
This visual pathway whas damaged in the patient Dr. P.
What is the what/ventral pathway?
100
This type of code can convey spatial information, but has more difficulty representing abstract concepts.
What are depicitive/analog codes?
200
Stabilized retinal images support this theory of pattern recognition.
What is feature theory?
200
This side of the brain is mainly responsible for processing verbal information.
What is the left hemisphere?
200
Patients with visuospatial neglect have damage to this side of their brain and will thus ignore the left side of their visual field because of this type of brain organization.
What is the right side and contralateral?
200
These types of cells have either an on-center/off-surround organization or vice versa.
What are ganglion cells?
200
When asked if there is a parallelogram in Star of David, people cannot do this in their heads, but can easily answer the question if they see a picture. This is a supports this theory.
What is Propositional theory/ Images are stored as propositional codes?
300
The existence of grandmother cells would support this theory.
What is template theory?
300
This theory states that we use verbal and visual codes to represent information
What is Dual-Code theory?
300
This techniques measures oxygen consumption in the brain with radioactive tracers.
What is PET?
300
These types of cells have a large receptive field, a transient response and detect movement
What are magno cells?
300
This hypothesis argues that people use same operations to serve same purposes in respective domains. For example, images are analogous to the physical things they represent.
What is the functional-equivalence hypothesis?
400
This theory can explain how we perceive the arrangement of features in an object, but this theory cannot.
What are RBC theory and feature theory?
400
I think that Ulrich’s and Michigan Book and Supply and closer together than they really are because of this.
What are semantic clusters?
400
This part of the neuron receives information from other neurons.
What are the dendrites?
400
The fact that we need groups of cells in order to recognize an object, not just one “grandmother” cell is called this.
What is population coding?
400
If images are stored in this way, then we’d expect that visual perception would interfere with a visual imagery task, but that auditory perception would not.
What are depictive codes?
500
These theories cannot explain how we recognize individual faces.
What are feature theory, template theory and RBC theory?
500
I am very familiar with Ann Arbor, but I am not very familiar with Detriot. When I imagine driving from Ann Arbor to Detriot, I estimate that it will take longer than the reverse direction because of this.
What is the observer perspective?
500
This is used to represent the somatosensory cortex by showing that more sensitive areas are bigger.
What is the homunculus?
500
The lateral geniculate nucleus receives information from these and send information to this area.
What are the ganglion cells (M & P cells) and the occipital lobe?
500
In Kossyln’s map experiment, he found this type of relationship between reaction time and distance between the 2 points on the map
What is linear?
