There are different ways in which the brain presents different ideas. The sensory
functional hypothesis establishes that the brain can differentiate a living thing from an artifact
and thus be able to code different concepts within the brain as presented by the physical features
of each group. For example, one can group different items as either living things or not without
necessarily touching them. The multifactor approach establishes that the brain can group
different concepts from the brain and other concepts from the environment, facilitating how they
are grouped into different categories. These two are similar as they focus on understanding
different concepts by coding or grouping them. They are also different as one focuses on a single
concept to various group items while the other focuses on multiple factors.
The semantic category approach argues that specific parts of the brain process specific
concepts. In this case, when an individual reads or hears a particular word, the associated neural
path is activated to determine its meaning. For example, a scent will stimulate a specific pathway
to identify the said scent. The embodied approach processes information through the body; thus,
the information is processed as linked to the associated motor behavior. For example, a hammer
is associated with its function of hitting a nail into a surface. These two are similar in that
knowledge is linked to other sensory parts of the body. It differs from the sensory-functional
hypothesis and the multifactor approach as, in this case, the brain has already found the different
meanings of concepts rather than grouping them according to physical traits to create knowledge.
