Answer:
Sparse coding
Explanation:
Sparse coding can be described or explained as a situation where items are encoded or represented by strong activation of a relatively small sets of neurons.
It should be understood that neurons code for the intensity of stimulus , and this is done in two ways which are
* Frequency coding...here, the firing rate of sensory neurons increases with increased intensity, and
* Population coding....here, the number of primary afferent responding increases.
In this case, the results derived or gotten from both Arthur's and Roger's faces supported the sparse coding.
