Verbal coding impacts visual matrix task performance. A modified Visual Patterns Test (VPT) limited verbal coding, resulting in a lower visual working-memory span compared to versions with higher verbal coding availability.

Area of Science:

  • Cognitive Psychology
  • Neuroscience

Background:

  • Verbal coding, the process of assigning verbal labels to visual information, is crucial for memory and task performance.
  • The Visual Patterns Test (VPT) is a standard tool for assessing visual matrix reasoning abilities.

Purpose of the Study:

  • To investigate the availability of verbal coding for patterns within the VPT.
  • To determine the effect of verbal coding availability on performance in a visual matrix task.

Main Methods:

  • A pilot study assessed the number of verbal labels participants could assign to VPT patterns.
  • A modified VPT was created using patterns with low verbal coding availability.
  • An experimental study compared performance on the modified VPT with a version allowing higher verbal coding.

Main Results:

  • Overall availability of verbal codes for VPT patterns was low, with significant variation between patterns.
  • The modified VPT, with limited verbal coding, yielded a lower visual working-memory span.
  • Performance on the visual matrix task was significantly influenced by the availability of verbal coding.

Conclusions:

  • Verbal coding plays a significant role in visual matrix task performance.
  • The modified VPT effectively reduces verbal coding, offering a tool to study visual processing independent of verbal strategies.
