What phenomenon does Hyman et al.’s (2010) study with the unicycling clown illustrate?
1) Change blindness
2) Inattentional blindness
3) Spatial neglect
4) Top-down control
Inattentional blindness
What commonality exists between change blindness and inattentional blindness?
1) Both involve memory deficits
2) Both result from a lack of attention
3) Both are caused by early selection only
4) Both require explicit tasks to occur
Both result from a lack of attention
Which of the following is true about inattentional blindness?
1) Memory is required to notice unexpected stimuli
2) It typically occurs during tasks requiring focused attention
3) Observers fail to compare successive scenes
4) It is unaffected by attentional allocation
It typically occurs during tasks requiring focused attention
What is a defining feature of change blindness?
1) It only occurs when attention is divided
2) Memory plays a key role in detecting changes
3) It is unrelated to attentional deficits
4) It never occurs during explicit tasks
Memory plays a key role in detecting changes
What does structural MRI reveal about the brain?
1) Functional connections between brain regions
2) Specific activity during tasks
3) The anatomy of the cerebral cortex and white matter
4) The effect of ventral attention networks on perception
The anatomy of the cerebral cortex and white matter
Which of the following are components of the dorsal attention network?
1) Ventral frontal cortex and temporal-parietal junction
2) Frontal eye field and intraparietal sulcus
3) Temporal-parietal junction and intraparietal sulcus
4) Frontal eye field and ventral frontal cortex
Frontal eye field and intraparietal sulcus
What is the main role of the dorsal attention network?
1) Stimulus-driven reorienting
2) Goal-driven orienting
3) Processing memory-based tasks
4) Detecting spatial neglect
Goal-driven orienting
Which hemisphere is primarily associated with the ventral attention network?
1) Left hemisphere
2) Right hemisphere
3) Both hemispheres equally
4) Neither hemisphere
Right hemisphere
What is the primary cause of spatial neglect?
1) Damage to the dorsal attention network
2) Damage to the ventral attention network
3) Memory impairments
4) Visual processing deficits
Damage to the ventral attention network
Spatial neglect most often results in neglect of which side of space?
1) Right side
2) Left side
3) Top side
4) Bottom side
Left side
What phenomenon is commonly seen in recovering spatial neglect patients?
1) Inattentional blindness
2) Change blindness
3) Extinction
4) Complete recovery of attentional capacity
Extinction
Why is spatial neglect considered an attentional deficit rather than a perceptual deficit?
1) Patients are aware of their deficits
2) It can affect imagination as well as perception
3) It is caused by memory impairments
4) It always involves auditory attention
It can affect imagination as well as perception
What percentage of patients with right hemisphere lesions experience spatial neglect?
1) 10%
2) 25%
3) 40%
4) 60%
40%
What role does memory play in change blindness?
1) None—it is unrelated to memory
2) It is required to compare successive scenes
3) It impairs attention to changes
4) It enhances detection of changes
It is required to compare successive scenes
Which of the following is NOT a condition that increases change blindness?
1) Rapid changes in a visual scene
2) Temporary occlusion
3) Slow changes in a stimulus
4) Empty frames between images
Rapid changes in a visual scene
What brain region is part of the ventral attention network?
1) Frontal eye field
2) Intraparietal sulcus
3) Temporal-parietal junction
4) Cerebellum
Temporal-parietal junction
How is spatial neglect typically diagnosed?
1) Through structural MRI scans
2) Using standardised neuropsychological assessments
3) By measuring memory performance
4) Observing visual deficits
Using standardised neuropsychological assessments
Which study highlighted radiologists missing anomalies in CT scans due to inattention?
1) Simon & Chabris (1999)
2) Hyman et al. (2010)
3) Drew, Vo, and Wolfe (2013)
4) Chabris and Simons (2010)
Drew, Vo, and Wolfe (2013)
What is the key difference between inattentional blindness and change blindness?
1) Inattentional blindness requires memory, while change blindness does not
2) Inattentional blindness occurs during explicit tasks, while change blindness does not
3) Inattentional blindness does not require memory, while change blindness does
4) Inattentional blindness is due to memory deficits, while change blindness is not
Inattentional blindness does not require memory, while change blindness does
