Form Perception (Winter 2023)

Which of the following most accurately describes a theory of object recognition?

• Geon theory suggests that simple geometric forms, stored in memory, allow us to identify all objects except for faces.

• Template theory suggests that we store ideal examples of objects we encounter and compare novel objects to these examples.

• Prototype theory helps overcome the storage problem of the template theory, as an exact match is not required when comparing novel objects to examples.

• Gestalt theory suggests that we organize visual input by looking at the individual parts of an object.

Jordan sees something flying very quickly above his head. He thinks it's a bee and gets scared, but after watching it land on the table, he can clearly see that it's a harmless ladybug. In what order were parts of Jordan's cortex activated during this scene?

• Parietal lobe via the ventral stream, followed by the temporal lobe via the dorsal stream

• Parietal lobe via the dorsal stream, followed by the temporal lobe via the ventral stream

• Temporal lobe via the ventral stream, followed by the parietal lobe via the dorsal stream

• Temporal lobe via the dorsal stream, followed by the parietal lobe via the ventral stream

Which of the following most accurately describes a Gestalt principle?

• Items that change in the same manner are grouped together and separated from other items, which is known as the figure-ground principle.

• Items that are close in space tend to be grouped together, which is known as the continuity principle. 

• Items that are physically similar tend to be grouped together, which is known as the proximity principle.

• Items that change in the same manner tend to be grouped together, which is known as the common fate principle. 

Brian can never seem to tell his keys apart from his wife's, even though his has a penguin keychain, while his wife's has an elephant keychain. However, if he has both sets of keys in his coat pocket, he has no trouble finding his keys at all. Which part of the brain might Brian have damaged and what condition could he have developed, as a result?

• Prosopagnosia, from damage to the visual association area.

• Prosopagnosia, from damage to the primary visual cortex.

• Visual agnosia, from damage to the visual association area.

• Visual agnosia, from damage to the primary visual cortex.

Which of the following is true about 4-month-old infants?

• They look longer at attractive faces than unattractive faces.

• They do not have a sense of size constancy.

• They look at an object's parts rather than the object as a whole.

• They do not have a sense of the principle of closure.
