WorksheetsU2 AoS2 DP4 Visual Illusions and Agnosia
Total questions: 10
Worksheet time: 5mins
What is the apparent-distance hypothesis?
The idea that objects appear smaller when closer
That the brain adjusts the perception of an object's size based on its perceived distance
The illusion where lines of equal length appear different sizes
The concept that distant objects are perceived as moving faster
Which visual perception principle is most challenged by the Ames room illusion?
Size constancy
Depth perception
Shape constancy
Figure-ground
Which aspect of the Spinning Dancer illusion can lead to the perception of the dancer spinning in different directions?
Changes in movement
Angle of view
Lack of depth cues
Sustained attention
How does depth perception contribute to the Müller-Lyer illusion?
It causes the line with inward-pointing arrows to look shorter because the arrows imply a closer proximity, reducing the perceived distance of the line
It affects the illusion by making the lines look different in length due to their colour contrast, which changes with distance
It influences the illusion by altering the perceived brightness of the lines based on their surrounding shapes
It makes the line with outward-pointing arrows appear longer because the arrows suggest that the line is at the end of a receding corner, creating the illusion of increased distance
What is a characteristic symptom of apperceptive visual agnosia?
Inability to recognise familiar faces
Loss of colour vision and difficulty distinguishing between colours
Difficulty in drawing or copying objects due to issues with perceiving shapes and objects correctly
Impaired ability to recognise spoken words
How does apperceptive visual agnosia typically affect object recognition?
Individuals can recognise objects but struggle to name them
Individuals have difficulty with recognising objects due to impaired shape and object perception, even though their basic visual acuity is intact
Individuals have no trouble recognising objects but have difficulty with spatial awareness
Individuals cannot recognise objects due to a loss of memory, rather than a visual perception issue
Which task would be likely be more challenging for someone with associative visual agnosia?
Copying a drawing of a familiar object
Naming a common object that is shown to them
Drawing a picture from memory
Identifying the colour of various objects
Which of the following scenarios is consistent with associative visual agnosia?
A person can correctly describe the shape and colour of an object but cannot identify what the object is
A person cannot perceive the shape of an object but can recognise it if shown again
A person has trouble seeing objects in three dimensions but can recognise them
A person struggles to copy a drawing of an object but can name it easily
Prosopagnosia primarily affects which aspect of perception?
Visual recognition of objects
Recognition of familiar faces
Ability to distinguish between different colours
Auditory recognition of voices
How does prosopagnosia relate to bottom-up processing in visual perception?
It results from an issue with top-down processing, not bottom-up processing
It is a condition where bottom-up processing is enhanced, leading to better face recognition
It primarily affects the brain's ability to use bottom-up processing to recognise faces
It disrupts both bottom-up and top-down processing equally
