Attention Flashcards
Describe simultanagnosia / balints
Describe the damage
cant integrate items - can only see things separately
bilateral posterior parietal damage.
Name the three categories of attention
Selective
Divided- attention has a limited capacity which can be divided between tasks
Sustained- if you’re interested in something, you have sustained attention to it
Name the two types of attention
Top down (active)- influenced by pt's own intentions and expectations and bottom up (passive)- stimuli in the world catch our attention
Name the two attentional systems
Ventral fronto-parietal network
Dorsal frontal parietal network
Name three ways to research attention
Cognitive psychology- behavioural studies of healthy participants
Cognitive neuropsychology- explain behaviour of patients with lesions in terms of models from cognitive psychology
Cognitive neuroscience- Neurophysiology, imaging provides link between brain and behaviour using PET, fMRI, ERPs etc
What does the posner cueing test show?
we are 80x faster at spotting an object when there is a cue
80x slower when the cue is wrong
- what does unilat parietal damage cause
2. what does bilat parietal damage cause
- neglect and extinction
2. balint syndrome
which side do you leave out in neglect
OPPOSITE to lesion
what is extinction
mild form of neglect with a double stimuli
