What is the requirement for attention?



Attention is

Selecting and focusing on relevant incoming stimuli in the environment


What are the 2 types of attention?

1) Spatial Attention
2) Attention in Action & Behaviour


Spatial attention is dominant in the ______ hemisphere



Where in the brain mainly is 'spatial representation and processing spatial information'?

Right parietal lobe


In terms of severity, spatial attention deficits can range from

Mild inattention (reduced attention sometimes, i.e. in complex situations) to neglect (never responds to stimuli on affected side/environment)


What are the theories of unilateral neglect?

1) Attentional system is out of balance (unaffected cortex over-rides the affected cortex)
2) Person may lose representation of the left space (person no longer has knowledge it exists)


Define unilateral neglect

Patients fails to attend or respond to meaningful stimuli on the affected side of the body or environment that side. This failure cannot be explained by sensory or motor deficits.


Motor neglect is an observed behaviour and is when

The person doesn't spontaneously use the affected limb in bi-manual tasks and can't be explained by sensory or motor deficits


Extinction is an observed behaviour when testing people who have neglect. This refers to:

A person identifying stimuli presented on each side separately.

When provided stimuli on both sides simultaneously fails to attend to stimulus on affected side


A person may show varying degrees of unilateral neglect ranging from

mild inattention to neglect


The Catherine Bergego Scale is a

Functional test to assess inattention/unilateral neglect


What are three simple tests to assess inattention/neglect?

1) Star Cancellation Test
2) Figure & Shape Copying Tests
3) Drawing Tests (i.e. drawing a clock)


Briefly, what are the 7 ways to treat spatial inattention/neglect?

1) modify environment
2) visual scanning training
3) eye patching
4) trunk rotation
5) limb activation
6) task related training
7) mirror therapy


Attention in action and behaviour refers to

Staying on task despite distractions


Perception is defined as

The process of turning sensory information into meaningful representations which are used to interact with the environment


Perception is a cognitive function that takes place in

the association areas of the parietal, temporal & occipital lobes


The ______ hemisphere is dominant for perception because of its role in spatial and mental representation



What happens in perceptual disorders?

Patient has impaired recognition or impaired spatial appreciation of stimuli despite the fact that sensory input is intact


Visual perception deficits cause confusion in:

1. Spatial Relations ( how objects around us relate to each other and to ourselves)
2. Geographical Orientation (finding our way in familiar and new environments
3. Figure ground discrimination and depth perception (distinguishing objects in the foreground from their background)
4. Recognising objects


Apraxia refers to:

unable to execute a voluntary act


Ideomotor apraxia is a motor _____

motor planning problem


Unable to carry out the action successfully when instructed can be referred to as

Ideomotor Apraxia


People with Ideomotor Apraxia may have less problems with

Routine/automatic tasks, especially in a familiar environment


What are some screening tests for ideomotor apraxia?

Gesture (show me how u would wave goodbye)
Copying the tester)
Performing Task on Demand (i.e. serial task)
Functional Task
