# Engineering Pareidolia: Mental Imagery, Perceptual Scaffolding, and Visual Creativity

## TL;DR

This paper explores how pareidolia, the tendency to see meaningful patterns in ambiguous stimuli, can be engineered and used to study visual creativity and perception.

## Contribution

It introduces engineered pareidolia as a framework for studying creative perception and its neural basis, bridging art and neuroscience.

## Key findings

- Engineered pareidolia can be understood as externally scaffolded mental imagery using minimal visual cues.
- Art-historical examples demonstrate how sparse cues can reliably trigger face-like perception through top-down inference.
- The framework may help quantify creative perception and relate it to neural signatures and clinical conditions like Lewy body disease.

## Abstract

What are the main findings?
Engineered pareidolia can be framed as a form of externally scaffolded mental imagery, in which minimal stimulus constraints elicit stable, template-based completion.Art-historical exemplars (Arcimboldo; Dürer; Leonardo) illustrate distinct “design regimes” through which sparse cues can reliably trigger face-like completion via top-down inference.

What are the implications of the main findings?
Engineered pareidolia may offer tractable paradigms to quantify creative perception (detection thresholds, robustness to perturbation, inter-observer reproducibility) and relate it to neural signatures.The framework could help bridge neuroaesthetics with clinically quantifiable pareidolia in Lewy body disease, informing models of altered precision/priors under uncertainty.

Pareidolia is often framed as a viewer-side illusion: a tendency to perceive meaningful forms—especially faces—in ambiguous inputs. This Concept Paper argues that pareidolia can also be deliberately engineered and therefore provides a tractable entry point into the neurophysiology of visual creativity. We propose a unifying construct in which engineered pareidolia functions as externally scaffolded mental imagery: minimal visual constraints recruit internally generated templates and top-down inference while remaining anchored to sensory input. To strengthen theoretical rigor, we define necessary and sufficient features that distinguish this construct from adjacent accounts (scaffolded cognition; perceptual scaffolding; bistable perception). Using Arcimboldo’s composite portraits and Dürer’s embedded face in View of the Arco Valley, plus a canonical Renaissance example (Leonardo’s Bacchus/Saint John the Baptist), we outline distinct “design regimes” that modulate cue validity, attentional release, and interpretive switching. We then connect engineered pareidolia to creativity research by linking pareidolia design and detection to measurable constructs in divergent/creative perception, including but not limited to Torrance-style domains, and we propose feasible behavioral and neurophysiological paradigms that control for artistic skill and clinical status. Finally, we distinguish benign pareidolia from hallucination, discuss clinical resonance in dementia with Lewy bodies where pareidolia can be quantified, and outline an empirically testable research program that reframes pareidolia as a bridge between imagination, perception, and creativity.
