Verbal descriptions of spatial information can interfere with picture processing

Area of Science:

• Cognitive Psychology
• Educational Psychology
• Human-Computer Interaction

Background:

• Multimedia learning theory suggests combining text and visuals can enhance comprehension.
• However, the effectiveness may depend on the type of information presented (spatial vs. visual).

Purpose of the Study:

• To investigate whether learning is improved by presenting text and pictures compared to text only.
• To test if this effect differs based on whether the text conveys spatial or visual information.

Main Methods:

• Experiment 1: 59 students learned with text (spatial vs. visual content) accompanied by pictures.
• Experiment 2: 85 students were randomly assigned to a 2x2 design (picture presentation: with/without; text content: visual/spatial).

Main Results:

• Both studies found interference when spatial text information was paired with pictures, leading to worse recall.
• Beneficial effects of adding pictures were observed only when text contained visual information.
• No differences in recall were found between visual and spatial texts when no pictures were present.

Conclusions:

• Presenting pictures alongside spatial information can impede learning due to processing interference.
• Visual information presented with pictures enhances learning, supporting principles of effective multimedia design.
• Learner performance is contingent on the congruence between text content modality and accompanying visuals.
