Summary

This study shows that when people solve multiplication problems, they sometimes get slowed down by the answer. This interference effect, seen in number-matching tasks, occurs at short time intervals.

Area of Science:

  • Cognitive Psychology
  • Experimental Psychology
  • Neuroscience

Background:

  • The number-matching task is used to study cognitive processes.
  • Previous research indicated an interference effect in addition facts.

Purpose of the Study:

  • To investigate interference effects in multiplication facts within a number-matching task.
  • To determine if the interference effect is due to obligatory activation or automatic counting.

Main Methods:

  • Participants verified target numbers presented after a masked cue (multiplication fact).
  • Stimulus Onset Asynchrony (SOA) varied between 100, 120, 220, and 350 ms.
  • Reaction times were measured for target verification.

Main Results:

Related Experiment Videos

  • A significant interference effect was observed at 100- and 120-ms SOAs.
  • Participants were slower to reject targets that were the product of the cue.
  • No significant interference effect was found at longer SOAs (220 and 350 ms).

Conclusions:

  • The findings demonstrate an interference effect in multiplication facts, consistent with prior research on addition facts.
  • The results support the interpretation that the interference effect arises from obligatory activation, not automatic counting.
