Question

Recent evidence presented in the assigned journal reading has suggested that seeing a hammer and a dog activate two different regions of the visual cortex. Which of the following statements does this finding support?

A) The modularity of the brain's visual processing system
B) The generalization of visual processing across stimuli
C) The concept of embodied cognition
D) The universality of visual cortex activation

Answer 1

This finding of separate regions of the visual cortex being activated by different stimuli supports the modularity of the brain's visual processing system, which includes specialized areas for processing different types of visual information.

Step-by-step explanation:

The evidence suggesting that the visual cortex has distinct regions activated by different stimuli supports the idea of the modularity of the brain's visual processing system. This concept aligns with the findings of German neuroscientist Korbinian Brodmann, who identified specific areas within the cerebral cortex associated with various functions, which include parts of the occipital lobe specifically linked to primary visual perception (Brodmann's areas).

Moreover, the visual association cortex (areas V2 and V3), which encircles the primary visual cortex (area V1), contributes to developing complex visual perceptions by adding color and motion information, integrating this with other areas like the temporal and parietal lobes through the ventral and dorsal streams of processing. The specialization of different regions in the visual cortex for processing different types of visual information, such as objects like a hammer and a dog, is fundamental to the modular approach to understanding brain function.
