Summary

The split effect in arithmetic sequence processing was studied using event-related brain potentials (ERPs). A late positive component (LPC) indexed this effect, showing amplitude increased with numerical distance from the correct answer.

Area of Science:

  • Cognitive Neuroscience
  • Mathematical Cognition
  • Psychophysiology

Background:

  • The split effect in arithmetic tasks involves longer reaction times for incorrect solutions near the correct one.
  • This effect is hypothesized to stem from different cognitive strategies: whole-calculation for small-split problems and plausibility-checking for large-split problems.

Purpose of the Study:

  • To investigate the neural correlates of the split effect in arithmetical sequence processing.
  • To determine if event-related brain potentials (ERPs) can differentiate processing strategies based on numerical distance.

Main Methods:

  • Participants verified the correctness of numerical sequences based on an established rule.
  • Sequences concluded with the correct number, a small-split incorrect number, or a large-split incorrect number.
  • Event-related brain potentials (ERPs) were recorded and analyzed, focusing on early negativity and late positivity components.

Main Results:

  • Two ERP components, an early negativity (approx. 270 ms) and a late positivity (550–650 ms), were observed when sequences were violated.
  • The late positivity component (LPC) exhibited a centro-parietal distribution.
  • LPC amplitude correlated positively with the numerical distance between the presented and correct sequence endings.

Conclusions:

  • The centro-parietal late positivity component (LPC) serves as a neural index of the split effect in arithmetic sequence verification.
  • Findings suggest the LPC reflects cognitive processes sensitive to the degree of numerical discrepancy, potentially related to strategy shifts.
