Human Factors Engineering - Midterm
Review UPDATED ACTUAL Exam
Questions and CORRECT Answers
Goal of human factors - CORRECT ANSWER - Enhance performance (increase speed,
productivity, reduce errors)
Improve safety (reduce injuries and fatalities)
Increase user satisfaction (better quality of life, system acceptance)
Task Redesign - CORRECT ANSWER - Focuses on changing what operators do rather
than changing the physical equipment they use. Modifying what actions people take (such as
reducing manual lifting with the help of machines).
Basic Research - CORRECT ANSWER - Aims to develop general principles and theories
across various tasks and settings
Applied research - CORRECT ANSWER - deals with real-world scenarios such as
studying the effects of texting and driving. Example cell phone use and driving relates more to
this type of research
(True or False) The experimental method consists of deliberately producing a change in one or
more dependent variables and measuring the effect of change on one or more independent
variables - CORRECT ANSWER - False
In an experimental method, independent variables are - CORRECT ANSWER -
manipulated or changed, and the effect of this manipulation is measured on the dependent
variables, not the other way around. Dependent variables are the outcomes or effects observed as
a result of manipulating independent variables.
This study assigns different groups of people to different conditions (cell phone use and traffic
conditions), so it is __________ where each group experiences only one combination of
,variables - CORRECT ANSWER - between-subjects design. all different groups (4
different groups)
When participants experience some conditions and are part of different groups for others, it is
________ design - CORRECT ANSWER - mixed-subjects design (some variables are
within subjects, and some are between-subjects) (2 different groups)
(True or False) Retrospective think-aloud protocols involve participants describing what they
were doing after the fact, possibly while watching themselves on video - CORRECT
ANSWER - True
(True or False) Heuristic evaluation enables designers to identify usability issues without
needing users, as expert evaluators use established heuristics to assess the system - CORRECT
ANSWER - True
Heuristics developed by Nielson include principles like - CORRECT ANSWER -
consistency, error recovery, help and documentation, and system-world match
(True or False) Accommodation refers to how the eye lens changes shape to focus on near or
distant objects - CORRECT ANSWER - True
Rods are responsible for - CORRECT ANSWER - low light vision
Cones are active in - CORRECT ANSWER - bright light and handle color vision
(True or False) The only way to increase the visibility of an object is to increase the light
intensity - CORRECT ANSWER - False. Visibility can also be improved by adjusting
contrast and other factors, not just light
Bottom up processing - CORRECT ANSWER - relies on real data from environment
, Top down processing - CORRECT ANSWER - uses prior knowledge
Frequency relates to the - CORRECT ANSWER - pitch of the sound
Loudness is related to - CORRECT ANSWER - amplitude
Sound levels above _______ are considered hazardous - CORRECT ANSWER - 85-90 dB
Motion sickness occurs when - CORRECT ANSWER - you feel something you don't see
Simulator sickness - CORRECT ANSWER - occurs when you see something you don't
feel
What is the main goal of Human Factors Engineering - CORRECT ANSWER - To
enhance human performance, safety, satisfaction
Which of the following is NOT part of Human Factors design considerations?
A. Task design
B. Equipment design
C. Environmental design
D. Economic cost reduction - CORRECT ANSWER - D.
Human factors primarily concern task, equipment, and environmental design, aiming to optimize
human interactions with systems
Which of the following is an example of applied research?
A. Studying the effect of new training methods on factory workers' productivity
