Question

What can be inferred about the role of the mental operator (M) in the Keystroke-Level Model (KLM)?

a.

It represents conscious decision-making during a task

b.

It signifies user frustration during task execution

c.

It is based on the user's typing speed

d.

It is used for calculating mouse movement times

Answer: (a).It represents conscious decision-making during a task Explanation:The mental operator (M) in KLM represents the mental preparation as the user recalls what to do next, reflecting conscious decision-making.
