Sense and Perception

Describe the Turing Test.

Explain how it demonstrates sense and perception.

Distinguish between sensation and perception.

Use examples to aid your answer.

Our brain sorts information in two ways. What are the two ways?

Describe them and explain the differences between them.

What is the problem with top-down activation?

What senses does a person have?

What is the typical pathway from sensation to perception?

Each form of sensory input has a specialised receptor, particular neurons through which it is sent and particular areas in the brain for processing.

To which sense or type of brain processing, do each area in the brain correspond to?

The brain consists of white and grey matter. What do these terms mean?

What is the corpus callosum?

What electromagnetic radiation are our eyes sensitive to?

How does this relate to our vision of a 24-hour day?

What terms do we use to describe vision?

How would we describe the vision acuity of an infant, using these terms.

In relation to the focusing of images, what types of vision impairment are there?

How is a visual field represented in the brain?

In relation to vision acuity, what types of defects in the visual field are there?

The corpus callosum is a very important structure that enables the transmission of information between the left and right hemispheres.

What happens if the corpus callosum is cut, like in split-brain patients?

Describe the colour-after effect.

Outline the neuronal pathway that visual input takes in the brain.

Distinguish between the two types of pathways that can take place from the thalamus.

What deficiencies affect the 'what' pathway?

Describe the McGurk effect.

What does this demonstrate in terms of sense and perception?

Sound waves are wave functions.

Describe its frequency and amplitude.

Outline how sound waves travel from the outer ear to the inner ear.

What types of deafness are there?

Olfactory input enters through the mouth and nasal pharynx. But other senses are also involved in the perception of flavour.

Describe an instance, and how this demonstrates sense and perception.

Outline the neuronal pathway that olfactory input takes in the brain.

It is often taught that our taste buds are divided into four sections: bitter, sweet, sour, salty

Why is this incorrect?

Often associated to vision is the concept of attention. We can attend to particular information or stimuli as a spotlight or focus on the whole array.

Distinguish between serial and parallel processing.

What is amodal completion? And why does the brain do this?

Explain using Kanzisa shapes.

Little is actually known about form recognition.

What is the most famous theory?

What is the superiority effect?

In what circumstances does it fail?

Humans have an inherent organised approach to the world. Gestalt proposed 7 organising principles, termed the Gestalt Laws. What are they?
