Vigilance in Various Professions

Signal-detection theory (SDT) is a framework to explain how people pick out the few important stimuli when they are embedded in a wealth of irrelevant, distracting stimuli. SDT often is used to measure sensitivity to a target’s presence. When we try to detect a target stimulus (signal), there are four possible outcomes: 1.) Hits (True positives) 2.) False Alarms (False positives) 3.) Misses (False negatives) 4.) Correct rejections (True negatives). SDT can be discussed in the context of ______— paying enough ______ to perceive objects that are there, perception— perceiving faint signals that may or may not be beyond your perceptual range (such as a very high-pitched tone), and memory— indicating whether you have/have not been exposed to a stimulus before, such as whether the word “champagne” appeared on a list that was to be memorized. Vigilance refers to a person’s ability to attend to a field of stimulation over a prolonged period, during which the person seeks to detect the appearance of a particular target stimulus of interest.

Divided attention: We prudently allocate our available attentional resources to coordinate our performance of more than one task at a time, as when we are cooking and engaged in a phone conversation at the same time. Main Functions of Attention include attending to short term and long term ______.
