Psychology, language, and computational models

Research questions, selected publications, and software associated with my work.

Conceptual representations and semantic geometry

My research examines what a computational representation should preserve about a concept. Single vectors are useful summaries, but may lose important information about contextual variation, relations between concepts, and representational change. Semantic subspaces offer one possible mathematical alternative; their advantages must be established empirically rather than assumed.

This work includes Quantum projections on conceptual subspaces (2023) and a methodological discussion published in Science Progress (2024). My provisional research programme, Beyond Point Representation, develops related questions about representational structure and psychological evidence.

My PhD thesis, De vectores a conceptos: nuevas rutas en la representación computacional del lenguaje (Autonomous University of Madrid, 2024), provides the earlier framework for this line of work. It was supervised by Guillermo Jorge-Botana and Ricardo Olmos. Thesis record in Dialnet ↗ · Full text in the UAM repository ↗.

Language models and psychological measurement

I study whether measures derived from computational language models capture psychological constructs, with particular attention to construct validity, out-of-sample generalization, and competing operationalizations. In 2026 I co-authored a study of language-model surprisal as an individual-difference measure.

Our cross-validation study of LIWC linguistic indicators (2022) further demonstrates why exploratory associations should be evaluated beyond their original samples.

Quantum-inspired cognitive modeling

I use tools from quantum-inspired probability and geometry as formal descriptions of selected cognitive phenomena. This does not imply that the brain is literally a quantum computer. The relevant question is whether the models yield falsifiable predictions and explain behavioral patterns beyond simpler classical alternatives.

Collaborations and research supervision

I contribute to AGRUPA (PID2024-157794NB-I00), a UAM-led research project examining stereotypes in cultural artifacts, as a member of its working team. I am currently based at UNED, where I teach statistics, computational methods, and research methodology in Psychology.
