U2 AoS2 DP4 Visual Illusions and Agnosia

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
