Key Findings

  • 01Eight distinct models of visual hallucinations exist, each based on different understandings of brain organization.
  • 02An integrated Visual Hallucination Framework has been developed, consistent with current theories of veridical and hallucinatory vision.
  • 03The framework delineates relevant cognitive systems and allows for systematic investigation of the link between hallucination phenomenology and cognitive structures.
  • 04The episodic nature of hallucinations suggests complex relationships between state and trait markers of hallucination risk.
  • 05The framework opens new avenues for research and potential treatment approaches.
02

Application

Design takeaway

When designing for users who might experience altered perception, consider the underlying cognitive mechanisms and the episodic nature of these experiences to create more robust and supportive systems.

How to apply

When designing virtual reality experiences, assistive technologies for individuals with neurological conditions, or even user interfaces in high-stress environments, consider how the cognitive factors outlined in this framework might influence user perception and interaction.

Project actions

  • 01When researching a complex human behaviour, look for opportunities to synthesize existing theories rather than focusing on just one.
  • 02Consider how different cognitive states might influence user interaction with your design.

Strengths & Limitations

Strengths

  • +Integrates multiple existing theories, providing a broader perspective.
  • +Facilitates systematic investigation and opens new research avenues.

Limitations

The complexity of visual hallucinations means that any single design project may only be able to explore a small subset of the factors involved.

Reliability & validity

The reliability of the framework lies in its systematic approach to integrating diverse models. Validity would be established through empirical testing of the framework's predictions regarding the relationship between hallucination phenomenology and cognitive markers.

Think critically

How might the 'episodic nature' of hallucinations, as described in the framework, influence the design of adaptive user interfaces that need to respond to changing user states?

05

Design Principles

"Integrate diverse theoretical models to create a comprehensive understanding of complex human perceptual phenomena for more effective design."

Understanding the mechanisms behind visual hallucinations is crucial for designing interventions and improving user experiences in contexts where perception can be altered. This integrated approach allows for a more holistic view, moving beyond isolated theories to a comprehensive understanding of the phenomenon.

06

What This Means for Your Design

Scientists have created a big picture map that combines different ideas about why people sometimes see things that aren't there. This map helps them study these experiences more easily and find new ways to help people.

How to use in your project

  • 1.Use the concept of synthesizing multiple models to justify your approach to investigating a complex design problem.
  • 2.Refer to the framework's emphasis on cognitive structures when explaining the user research phase of your design project.
