Question 6 0.5 pts Which is NOT a correct statement about Human Factors? Understanding human capabilities and limitations is an important component of Human Factors. Training is not a major research component in Human Factors. Human-centered design is one of the core approaches in Human Factors, In Human Factors, a "user" is the preferred term over a "customer" or "client". Participatory design does not mean having users design the product. Question 7 0.5 pts Which is NOT a correct statement about visual search? Top-down processing does not influence a visual search task performance. Search time equals (NXT/2), where N = number of items and I = time you spent on each item. Serial search is an attentive process. In parallel search, the number of distractors does not matter. If the target pops out due to its salient property, it is a pre-attentive search process. 0.5 pts Question 8 Which is NOT a correct statement about automaticity? The cocktail party effect is an example of automaticity. The Stroop effect is an example of automaticity. All of these statements are correct. We can train people to develop "automaticity" for a certain task. In Human Factors, a machine is automated, but a human skill is "automatized." Question 9 0.5 pts Which is NOT a correct statement about the effects of automation? Efficiency will increase. Operators' situation awareness will increase. Operators' workload will decrease. Safety will increase with automation Accessibility will increase. Question 10 0.5 pts Which is a correct statement about just noticeable difference? Fechner proposed that the size of the detectable difference is a constant proportion of the level of the stimulus. Weber proposed that the magnitude of subjective sensation increases proportionally to the logarithm of stimulus intensity. Like an absolute threshold, the difference threshold is defined by the point at which the change in stimulus can be detected 50% of the time. None of the these is correct. At extreme levels, Weber's constant ratios describe our ability to detect change fairly well. D Question 11 0.5 pts Which is NOT a correct statement about displays? Displays tell the operator what the system is doing. Displays tell the operator what needs to be done. Displays act as a medium between information in a system and the operator. Displays tell the operator how the system functions. Displays are considered as "input" from the system's perspective
