AGNOSIA- Apperceptive, Associative And Prosopagnosia

Question 1

Agnosia

Answer 1

A neurological Without knowledge condition

Question 2

Visual agnosia

Answer 2

A brain disorder involving inability to recognise familiar stimuli through the use of one or more senses despite the sense functioning normally otherwise this means the individual suffering from agnosia have difficulty identifying sensory information such as objects.

Commonly associated with brain lesions that occur in the parental lobe temple lobe and occipital lobe

Question 3

Visual agnosia

Answer 3

A brain disorder involving inability to recognise familiar stimuli through the use of one or more senses despite the sense functioning normally otherwise this means the individual suffering from agnosia have difficulty identifying sensory information such as objects.

Commonly associated with brain lesions that occur in the parental lobe temple lobe and occipital lobe

Question 4

What are the two types of visual agnosia

Answer 4

Apperceptive visual agnosia and associative visual agnosia + pruspagpodia

Question 5

Definition of Apperceptive visual agnosia

Answer 5

An inability to recognise familiar visual stimuli due to problems with processing perceptions the problem is not just in recognising the stimulus but in perceiving it at all

(inability to interpret and recognise)

Question 6

Symptoms of Apperceptive visual agnosia

Answer 6

Difficulty recognising objects by sight
Problems with copying or drawing objects
Inability to distinguish shapes and patterns

Question 7

Causes of Apperceptive visual agnosia

Answer 7

Is a neurological disorder that is typically caused by brain injury, particularly of the parietal and occipital lobes. Common causes of brain injury include physical.

Question 8

Example of Apperceptive visual agnosia

Answer 8

A person may look at a dinner plate and not be able to recognise it is a dinner plate they could describe it to you but if you showed them a picture they could not tell you what it was

Question 9

Definition of Associative visual agnosia

Answer 9

Refers to the condition where individuals can perceive and describe visual stimuli but cannot associate them with their meaning

(Can draw,but still no meaning)

Question 10

Symptoms of Associative visual agnosia

Answer 10

Ability to copy or draw objects correctly
Ability to describe the shape colour and texture of an object but cannot identify it
Difficulty and recognising similar objects

Question 11

Causes of Associative visual agnosia

Answer 11

Is often associated with lesions in the temporal lobe

Question 12

Example of Associative visual agnosia

Answer 12

A person could also tell you what a dinner plate is the difference is that if they are given a drawing of a dinnerplate, they could copy it

Question 13

Key differences between Apperceptive and Associative

Answer 13

Apperceptive Can form a stable perception of the object nor recognise, as well as not being able to draw or copy and image. While associative individuals can perceive the object but cannot link that perception to meaning, individuals can copy or draw an image because their perception is intact.

Question 14

Prosopagnosia

Answer 14

Involves an inability to recognise the faces of familiar people despite having no memory dysfunction, memory loss or impaired visual sensation.

Cannot perceive facial expressions and rely on other cues such as hair and clothing to identify people.

Tends to be congenital (have it from birth)
