Answer to Question 1

In selective attention, we choose to attend to some stimuli and ignore others. Focusing our attention helps us execute other cognitive processes, such as verbal comprehension or problem solving.

In divided attention, we engage in more than one task at a time, and we shift our attentional resources to allocate them as needed.

Answer to Question 2

Signal-detection theory was one of the first theories to suggest an interaction between the physical sensation of a stimulus and cognitive processes such as decision making. It posits the following outcomes:
Hits: The stimulus is presented and it is correctly detected.
Misses: The stimulus is presented but it is not detected.
False alarms: The observer reports that the stimulus has been presented when it has, in fact, NOT been presented.
Correct rejections: The observer reports that the stimulus was NOT presented and it was, in fact, NOT presented.
