Hypothesis

Does the speed of numerical magnitude processing differ between children and adults in controlled and automatic number comparison tasks?

Conclusion

Children process numerical magnitude at a similar speed as adults, but their response interference is greater due to less developed executive functions.

Supporting Evidence

  • Both children and adults showed significant EEG distance effects in numerical comparison tasks.
  • Children's response times were slower than adults, indicating developmental differences in executive functions.
  • Interference effects were more pronounced in children, suggesting challenges in response inhibition.

Takeaway

Kids can think about numbers as fast as adults, but they sometimes get confused and take longer to answer because they are still learning how to control their responses.

Methodology

Participants completed numerical and physical comparison tasks while their EEG was recorded to measure response times and brain activity.

Potential Biases

Potential bias in participant selection as all children were from the same public school.

Limitations

The study focused on specific age groups and may not generalize to all children or adults.

Participant Demographics

Participants included 14 grade 3 children (mean age 9.5 years), 16 grade 5 children (mean age 11.6 years), and 16 young adults (mean age 21.6 years).
