20 Questions

You read a paper that studied the object recognition abilities of a group of patients with temporal lobe lesions. That paper describes what sort of cognitive psychology research?

Cognitive neuropsychology

You are designing an experiment to test your hypothesis that the strength of the physical connections between the occipital lobe and temporal lobe underlies participants' speed of face recognition. What method from cognitive neuroscience is the most appropriate to use?

Diffusion tensor imaging

EEG and ERPs have high spatial resolution.

False

What is Diffusion Tensor Imaging?

A type of Structural MRI that measures how water diffuses across white matter.

DTI produces a map of white matter.

True

How many Teslas (1 = 10,000 Gauss) does the magnetic field of an MRI have?

1

Define the Bottom - up approach.

Stimulus that leads to firing of neurons to produce an image in the mind.

Subtraction Logic = Method used to isolate cognitive processes.

True

Information that hits the right side of the retina gets processes in the left side of the Visual cortex and thalamus.

False

List the properties of visual neurons.

Receptive fields, Retinotopy & lateral inhibition.

Lateral inhibition - when two neurons next to each other are firing one inhibits the other. This leads to enhancement in edges and lines in what we see.

True

Blindsight is due to...

Damage to the visual cortex (particularly V1).

The Geniculostriate route is for unconscious vision.

False

What are the symptoms of patients with Blind sights?

Unable to report seeing things (no conscious processing).

Colour constancy = the brain creates a construction of our perception (seeing objects in their original colour even in the presence of coloured light). This is a top down influence.

True

Hering 1878 states

Due to collour being the difference between cones, electrochemical signals sent to the brain state something falls between 2 cones (e.g. red and green).

Which range of the visible light spectrum is the human eye is most sensitive to light.

Green

Transduction = electrochemical patterns are converted into physical energy.

False

What are the stages of processing visual information?

Reception, transduction & coding

In the Functional Specialisation Theory which animals did Zeki 1992;1993 study?

Monkeys

Test your knowledge about blindsight, unconscious vision, and related phenomena like colour constancy and transduction. Explore the symptoms and theories related to these fascinating aspects of human perception.
