what are 3 aspects of cognition?
communication
learning
behavior
differentiate selective, sustained, alternating, and divided attention.
selective - selectively attend to spoken instructions, and become easily distracted by nearby conversations and noises
divided - only focus on one task at a time
sustained- prevent from seeing details of a task
alternating - cannot perform same task if an interruption occurs
what innervation strategies can be used to increase feedback toward the paretic side for someone with hemineglect?
have them exaggerate body movements and use perceptual anchors. this can include rotating the patients trunk towards the side they neglect using a brightly colored object.
what is scanning training used for?
used to teach a patient with neglect a more effective visual scanning pattern.
what is the difference between implicit and explicit learning?
why might this be important especially for individuals with cognitive deficits?
explicit learning - is guided there is step by step instructions and person is aware they are trying to learn something.
implicit learning - unguided action that occurs subconsciously. we don’t have to think about what we are doing.
they may need to use more explicit learning as they adapt.
what is apraxia ?
results from damage to both frontal and parietal lobes
ideational apraxia
does not understand the meaning of an object.
may verbally describe, but cannot perform.
ideamotor apraxia
result of lesion to dominant hemisphere that is not language based but more cognitive and perception in nature.
cannot perform a task on command
figure ground discrimination
cannot recognize distance
spatial relation
ability to locate objects in space
topographical orientation
difficulty going from one location to another
attention deficit
seen with right hemisphere damage. characterized by the inattention of the paretic side (usually left side) may neglect objects
