Chapter 5: Problem 1

An EEG would indicate primarily _____ activity while you take this test. A. alpha B. beta C. delta D. theta

Short Answer

Expert verified
Answer: B. Beta

Step by step solution

01

Understanding the brainwaves

First, we need to understand the characteristics of the given brainwave activities. Here's a brief overview: - Alpha waves: These waves occur during relaxation, meditation, and when the brain is idle. They have a frequency range of 8-12 Hz. - Beta waves: These waves are associated with alertness, focused concentration, problem-solving, and decision-making. They have a frequency range of 12-30 Hz. - Delta waves: These waves occur during deep sleep or unconsciousness. They have a frequency range of 0.5-4 Hz. - Theta waves: These waves are associated with drowsiness, daydreaming, or light sleep. They have a frequency range of 4-8 Hz.
02

Analyzing the situation

Since the question is asking about the primary brainwave activity during a test, we can eliminate Delta waves as they occur during deep sleep or unconsciousness. Theta waves can also be ruled out as they are associated with drowsiness or daydreaming, which is not the ideal state for taking a test. Between Alpha and Beta waves, the key difference is that Alpha waves are associated with relaxation and idle brain activity, whereas Beta waves are linked to alertness, focused concentration, problem-solving, and decision-making.
03

Identifying the correct option

Given the characteristics of the brainwaves, we can conclude that Beta waves (Option B) would be the primarily dominant brainwave activity during an EEG while taking a test, as it is associated with alertness, concentration, and decision-making, which are all required for effective test-taking. So, the answer is B. Beta.
