Scenario II While We Effortlessly Identify Most Objects by Sight, the Mechanisms

Multiple Choice

Scenario II
While we effortlessly identify most objects by sight, the mechanisms underlying how and where we make these identifications are matters of theoretical and empirical debate. According to image-based theories, previously identified objects are stored in memory as templates, which are consulted when identifying current retinal images. In contrast, parts-based theories state that the brain uses the component geometric elements (termed geons) comprising the object, as well as the spatial relationships between these geons, for purposes of identification. Where in the brain these identifications occur also is a matter of debate. Modular theories state that specialized areas, or modules, of the brain code categories of objects whereas distributed representation theories posit that it is the pattern of brain activity in multiple brain regions that identifies an object.
-(Scenario II) A geon is to an object as a:

• A)letters are to words.
• B)building is to bricks.
• C)letter is to its numerical position within the alphabet.
• D)sentence is to the words comprising it.
