Attention Flashcards
Intraparietal sulcus/Intraparietal lobule (Ips/IPL)
Controlled, preparing to attention and setting goals
FEF
Frontal eye fields
ventral frontal cortex
(VFC)
Automatic attentional orienting
TPJ
temporoparietal junction
Endogenous attention:
When an individual chooses what to
pay attention to (goals and intention)
- Top-down processing
- Intraparietal sulcus (IPS) and FEF
Exogenous attention:
When stimuli in the environment
drives us to pay attention
- Bottom-up processing
- Temporo-parietal junction (TPJ) and VFC
Spatial neglect is caused by
Damage to the right hemisphere, ventral parietal cortex
Spacial neglect causes
Left side of the world is out of awareness
Balint Syndrome is caused by
Bilateral parietal and occipital lobe damage
Balint Syndrome causes
Can’t focus on more than one thing; Can see local features but struggle to see global features
Optic ataxia:
problems with grasping or visual
control
Oculomotor apraxia:
Inability voluntarily shift gaze
Simultanagnosia:
Inability to identify or use more than one object in a scene
Sustained attention (Vigilance)
Top-down attention: Maintain focus on one input for a long period of time
Divided attention (Multitasking)
Top-down attention: Shifting attentional focus between tasks
Selective attention
Top-down attention: Focus on one input and ignore other information
Broadbent’s early selection filter model
filter information at the level of perception, before information
is processed for meaning
Treisman’s attenuator model
early filter dials down the influence of unattended material
Late selection filter models
process input to the level of the meaning, and then select what we want to process further
Stroop Task
The name of colors in various colors experiments
The load theory
Attentional filtering (selection) can occur at different points of processing, depends on the amount of information
load theory: difficult task with a high load
early filter
load theory: easier task with a low load
late filter
Change blindness
The failure to detect changes in stimuli
