Overview
Cognitive load refers to the amount of mental effort required to process information. In audio-only games, all gameplay information must be decoded through sound, making cognitive load a central design concern.
Types of Cognitive Load
- Intrinsic load: inherent complexity of the task
- Extraneous load: unnecessary mental effort caused by poor design
- Germane load: effort related to learning and mastery
Audio-only games must minimize extraneous load while supporting germane load.
Sources of Load in Audio Games
Common contributors include:
- Overlapping sound cues
- Ambiguous audio mappings
- Rapid information delivery
- Lack of auditory hierarchy
Design Strategies
Effective audio-only games manage cognitive load by:
- Structuring sounds hierarchically
- Using repetition and consistency
- Introducing mechanics gradually
- Reinforcing learning through predictable feedback
Implications for Accessibility
High cognitive load disproportionately affects new players and users with sensory processing differences, making careful design essential for inclusive gameplay.
