1. What is human factors engineering?
a) The study of human behavior in social settings
b) The design and arrangement of products, systems, and environments to fit the capabilities and limitations of human beings
c) The study of mechanical engineering principles applied to human biology
d) The study of genetics and its impact on human performance
Answer: b) The design and arrangement of products, systems, and environments to fit the capabilities and limitations of human beings.
Explanation: Human factors engineering focuses on optimizing the interaction between humans and the systems they use, considering factors like ergonomics, usability, and safety.
2. Which of the following is NOT a characteristic of man-machine-system?
a) Adaptability
b) Consistency
c) Inflexibility
d) Feedback
Answer: c) Inflexibility
Explanation: Man-machine systems are designed to be adaptable to varying tasks and environments, consistent in operation, and provide feedback to users.
3. Relative capabilities of human beings and machines are best described as:
a) Humans are always superior to machines in all tasks.
b) Machines are always superior to humans in all tasks.
c) Humans and machines each have unique capabilities that can complement each other.
d) Humans and machines have identical capabilities.
Answer: c) Humans and machines each have unique capabilities that can complement each other.
Explanation: Humans excel in tasks requiring creativity, intuition, and complex decision-making, while machines excel in tasks requiring speed, precision, and processing large amounts of data.
4. What is the primary purpose of developing and using human factor data?
a) To replace human workers with machines
b) To understand how humans interact with technology and environments for better design
c) To prove the superiority of machines over humans
d) To develop advanced AI algorithms
Answer: b) To understand how humans interact with technology and environments for better design
Explanation: Human factor data helps designers create products and systems that are more intuitive, efficient, and safe for human use.
5. Information theory primarily deals with:
a) How humans process sensory inputs
b) How information is stored in computers
c) How information is transmitted and processed
d) How information impacts decision-making
Answer: c) How information is transmitted and processed
Explanation: Information theory focuses on quantifying information and understanding the fundamental limits of communication and data processing systems.
6. Which factor does NOT affect information reception and processing?
a) Noise
b) Attention
c) Memory
d) Emotions
Answer: c) Memory
Explanation: While memory can impact information processing over time, it is not a factor affecting immediate reception and processing.
7. The process of coding sensory inputs involves:
a) Deciphering encrypted messages
b) Translating sensory stimuli into neural signals
c) Converting digital information into analog signals
d) Encoding data onto physical storage devices
Answer: b) Translating sensory stimuli into neural signals
Explanation: Coding sensory inputs refers to the process by which the nervous system translates various sensory stimuli (such as light, sound, or touch) into electrical signals that the brain can interpret.
8. Selecting sensory inputs involves:
a) Filtering irrelevant information and focusing on relevant stimuli
b) Amplifying all sensory inputs equally
c) Ignoring all sensory inputs
d) Randomly processing sensory information
Answer: a) Filtering irrelevant information and focusing on relevant stimuli
Explanation: Selecting sensory inputs involves the brain’s ability to prioritize and focus on relevant sensory information while filtering out irrelevant stimuli.
9. What is a key characteristic of human-machine interfaces?
a) Complexity
b) Simplicity
c) Unreliability
d) Incompatibility
Answer: b) Simplicity
Explanation: Human-machine interfaces are most effective when they are intuitive, easy to use, and require minimal training or effort from the user.
10. Which of the following is NOT a type of man-machine-system?
a) Closed-loop systems
b) Open-loop systems
c) Hybrid systems
d) Organic systems
Answer: d) Organic systems
Explanation: “Organic systems” do not typically refer to man-machine systems; they usually pertain to living organisms or biological processes.
