The behavior described reflects a disruption in conceptualizing and planning a multi-step action. This kind of apraxia is ideational apraxia, where the ability to form a plan of the movements needed to complete a complex task is impaired. People with ideational apraxia often show difficulty sequencing the steps or choosing the correct actions and tools for a task, even though their motor strength and the basic knowledge of how to use objects may be intact. The frontal lobes are involved in organizing, sequencing, and coordinating purposeful actions, so damage there can disrupt the overall plan for how to carry out a task.

This focus on planning and sequencing helps distinguish ideational apraxia from ideomotor apraxia, where the conceptual plan is present but there’s a breakdown in translating that plan into actual movement (often seen when performing on command or imitation). Constructional apraxia would involve problems with assembling or drawing objects, not the sequencing of a complex, tool-using behavior. And a general label of apraxia is too broad to capture this specific planning deficit.
