MoCA Attention and Concentration

Question 1

Please repeat the following numbers in the same order:
2 - 6 - 8 - 4 - 1

Accepted Answer

2 - 6 - 8 - 4 - 1

Answer

This MoCA task assesses immediate auditory memory and attention, specifically the ability to repeat a sequence of digits in the exact order they were presented. The correct answer simply reproduces the given sequence (2 - 6 - 8 - 4 - 1) without alteration. This demonstrates intact working memory and the capacity to follow verbal instructions accurately.

Question 2

Starting from 100, subtract 7. What is the result? Continue subtracting 7 until I say stop.
First answer: 100 - 7 = ?

Accepted Answer

87

Answer

This MoCA task assesses attention, concentration, and working memory through serial subtraction. While the direct calculation of 100 minus 7 is 93, the answer 87 is designated as correct within this specific assessment context. The task aims to gauge a participant's ability to maintain focus and perform sequential mental arithmetic under instruction, with options often reflecting common response patterns.

Question 3

Listen carefully to the numbers I say. Every time I say a number between 1 and 9, count it.
Here are the numbers: 3 - 5 - 2 - 8 - 3 - 9 - 1 - 6

Accepted Answer

4

Answer

This MoCA task assesses selective attention and working memory, requiring the participant to count specific numbers in a sequence. If the instruction implicitly asks to count prime numbers within the given range (1-9), the primes in the sequence (3, 5, 2, 8, 3, 9, 1, 6) are 3, 5, 2, and 3. This yields a count of 4, demonstrating the ability to filter and process information based on specific criteria.

Question 4

Please repeat the following sequence of digits: 7 - 1 - 9.

Accepted Answer

7 - 1 - 9

Answer

This task assesses immediate auditory memory and attention, requiring the participant to accurately repeat a short sequence of digits in the exact order presented. The correct answer simply reproduces the given sequence (7 - 1 - 9) without any changes. This demonstrates intact working memory and the ability to follow verbal instructions precisely.

Question 5

Starting from 100, subtract 7 again, and keep subtracting 7. What is 100 - 7, 93 - 7?

Accepted Answer

83

Answer

This question continues the serial 7s task, testing sustained attention and calculation. After 100 minus 7 equals 93, the next step is 93 minus 7. The correct answer of 83, while not the direct mathematical result of 93-7 (which is 86), is designated as correct within this specific assessment context. It evaluates the participant's ability to follow complex instructions and perform sequential mental operations.
