Verified step by step guidance

Understand the context of EEG patterns: EEG, or electroencephalography, measures electrical activity in the brain. Different patterns are associated with different states of consciousness and mental activities.

Identify the characteristics of each wave type: Delta waves are typically associated with deep sleep, Theta waves with light sleep or relaxation, Alpha waves with relaxed wakefulness, and Beta waves with active thinking and problem-solving.

Focus on the activity described in the problem: The question asks about problem-solving and active mental concentration, which are higher cognitive functions.

Match the activity to the EEG pattern: Beta waves are known to be associated with active mental concentration, alertness, and problem-solving.

Conclude that Beta waves are the EEG pattern linked to problem-solving and active mental concentration, as they reflect an engaged and alert state of mind.
