Research Programmes

Three active research streams investigating the boundaries of projective phenomena and their implications for human cognition.

Stimulus Equivalence

Stimulus Equivalence and Digital Reproduction

Examining whether digitised projective stimuli maintain perceptual fidelity to physical originals. Paired-administration protocols compare response patterns across physical and digital presentations.

Construct Stability

Construct Stability Across Populations

Investigating whether projective assessment constructs maintain consistent factor structures across culturally and linguistically distinct populations. Builds on foundational cross-population variance research.
