CPE Cognitive Ergonomics & Mental Workload Questions and Answers Flashcards

Human reliability analysis (HRA) techniques such as THERP are used for what purpose?

Answer: Quantifying the probability of human error in complex systems

HRA techniques like THERP (Technique for Human Error Rate Prediction) estimate the probability of human errors in procedural tasks to support risk analysis.

What is 'mode error' in human factors and ergonomics?

Answer: Performing the wrong action because the system is in an unrecognized mode

Mode error occurs when a user performs an action appropriate for one system mode while the system is actually in a different mode, leading to unintended outcomes.

The GOMS model (Goals, Operators, Methods, Selection rules) is primarily used to:

Answer: Predict execution time and sequence of user actions in HCI tasks

GOMS is a cognitive modeling framework that predicts the time and sequence required for experienced users to complete specific computer interaction tasks.

Which principle of display design states that information needed together should be displayed together?

Answer: Principle of proximity compatibility

The proximity compatibility principle states that information that must be mentally integrated for a task should be physically proximate on the display.

Which of the following best describes 'automation complacency' in ergonomics?

Answer: Reduced monitoring vigilance and over-reliance on automated systems

Automation complacency is the tendency for operators to reduce active monitoring when automated systems are in place, increasing risk when automation fails.

Cognitive load theory in instructional design suggests that effective training should:

Answer: Manage intrinsic, extraneous, and germane cognitive load to optimize learning

Cognitive load theory holds that training should reduce extraneous load (poor design), manage intrinsic load (task complexity), and promote germane load (schema formation).
