Vision & Occupation
These retinal receptors support color vision and visual acuity.
What are cones?
This structure receives light-sensitive information from the retina and carries it toward the brain.
What is the optic nerve?
This executive function skill allows a person to start a task independently.
What is initiation?
This type of assessment measures performance during real-world occupations rather than isolated cognitive skills.
What is a performance-based assessment?
A client repeatedly asks the same question every five minutes despite receiving an answer.
What is impaired short-term memory?
These retinal receptors support peripheral vision and low-light vision.
What are rods?
This structure is where portions of visual information cross to the opposite side of the brain.
What is the optic chiasm?
This executive function skill allows a person to shift between tasks or ideas.
What is cognitive flexibility?
The Kettle Test is designed to evaluate cognition during performance of this everyday activity.
What is preparing a hot beverage?
A client misses all objects located on the left side of a page during a cancellation task.
What is unilateral neglect?
The dorsal visual stream is often called the ______ stream.
What is the action stream?
This visual stream is responsible for object identification and recognition.
What is the ventral stream?
A client continues using the same unsuccessful strategy despite repeated errors. Which executive function is impaired?
What is cognitive flexibility?
An OT chooses a paper-and-pencil cognitive screen but suspects it may not predict actual daily performance. What additional assessment type should be considered?
What is a performance-based assessment?
A client knows what a toothbrush is for but attempts to brush with the bristles facing away from the mouth.
What is an ideomotor praxis deficit?
The ventral visual stream is primarily responsible for:
What is object identification?
This visual stream connects the visual cortex with the parietal lobe and supports action based on visual information.
What is the dorsal stream?
A client repeatedly forgets the next step while making coffee despite understanding the goal. Which executive function is likely impaired?
What is working memory?
A client performs well on standardized testing but cannot safely manage medications at home. This highlights the importance of assessing:
What is functional cognition?
A client begins putting on shoes before socks during dressing despite understanding the task.
What is an ideational praxis deficit?
A client reports seeing double due to ocular misalignment. What is the general term for this alignment problem?
What is strabismus?
A client can see an object but cannot recognize what it is. Which visual processing stream is most likely affected?
What is the ventral stream?
The Executive Function Performance Test primarily evaluates executive function during what type of activities?
What are functional tasks/occupations?
Why do occupational therapists often assess cognition during occupations instead of isolated testing alone?
Because occupational performance provides the most authentic picture of functional cognition.
A client requires verbal cues to begin grooming despite having adequate strength and range of motion.
What is impaired initiation?
