Sensory, perception, and cognition Flashcards
Types of sensory awareness?
Detection
Discrimination
Quantification
Recognition (temporal lobe)
What does interpretation mean?
Ability to make sense in time and space of a sensory stimulus
What is attention?
Ability to focus on one stimulus at the exclusion of others when necessary
What is intrapersonal vs extrapersonal space?
Intrapersonal= within the body Extrapersonal= at a distance (ex:visual, auditory, heat and cold)
Consequences of sensory impairments?
Loss of active movement Loss of “tone” hypotonia Loss of ability to sustain muscle contractions Due to loss of sensation Inability to sustain grip Modulate in CNS
What are three perceptual and cognitive impairments that we discussed in class?
Neglect
Agnosia
Apraxia
T or F: Unilateral spacial neglect is most common/more severe with a right sided stroke.
True
What is neglect?
Inability to direct attention to stimuli located on the side contralateral to a lesion
Lack of recognition of body part
Lack of recognition of ½ of visual field
What is the difference between homomynous hemianopsia and neglect?
A person with neglect will not recognize that they have a deficit whereas a person with HH will know.
What is visual object agnosia?
Can describe an object but cannot put a name to the object.
What is prosopagnosia?
Inability to recognize familiar faces.
What is apraxia and give an example.
Difficulty performing a willful purposeful movement or initiating movements not accounted for by weakness, sensory loss, incoordination, inattention or lack of comprehension.
Verbal, buccofacial (majority, children), limb (ideational, ideomotor), constructional, and dressing
What are consequences of sensory, perceptual or cognitive impairments (4 that were specifically talked about in class-general categories)?
Movement
Safety
Postural control
Social / behavioral
What is an examination of Interpretation of Extrapersonal Space?
Draw a daisy/clock/house
Block design tests
What is cognition?
the ability to process, sort, retrieve and manipulate information
