Multiple choices for this question have not been provided. I will however, go ahead and answer it.
Cognitive functions allow us to
receive, select, transform, store, develop and recover info that we have
received from external stimuli. Selective attention is a complex mental process
of focusing on a particular object in an environment. Thus, the brain is able
to pick and choose specific information to take in and specific information to
ignore through selective attention. It is able to select between stimuli that
reach our brain simultaneously, both through visual and audio.
