Knowledge revision processes during reading: How pictures influence the activation of outdated information

Area of Science:

• Cognitive Psychology
• Educational Psychology
• Human-Computer Interaction

Background:

• Outdated information hinders learning and knowledge revision.
• Understanding factors influencing outdated information activation is crucial for effective learning.

Purpose of the Study:

• To investigate how illustrating updated or outdated information with pictures affects the activation of outdated information.
• To examine the influence of picture content on reading times and cognitive processes during knowledge revision.

Main Methods:

• Three online experiments (N=1284) were conducted.
• Participants read texts with updated or outdated information, with or without illustrations.
• Reading times for target sentences were measured to assess cognitive processing.

Main Results:

• Illustrated texts led to faster reading times compared to non-illustrated texts.
• Illustrating updated information resulted in longer reading times than illustrating outdated information.
• Pictures generally facilitate cognitive processes, but their content significantly impacts reading efficiency.

Conclusions:

• Visual aids can enhance reading comprehension and knowledge revision.
• The content of illustrations is critical; updated information visuals are more impactful than outdated ones.
• Findings contribute to theories of knowledge revision and reading comprehension regarding the role of visuals.
