Are you interested in investigating how smart AI-models are? Do you want to conduct research on what characterizes intelligence in humans and AI and develop psychometric methods and formal models to describe the similarities and differences?

Are you interested in investigating how smart AI-models are? Do you want to conduct research on what characterizes intelligence in humans and AI and develop psychometric methods and formal models to describe the similarities and differences?
We are looking for a PhD candidate to join our research project entitled “How smart is AI really? Methods for investigating intelligence in humans and AI”, funded by a NWO Vidi grant awarded to Claire Stevenson. This project is led by dr. Claire Stevenson (PI), dr. Han van der Maas (promotor) and dr. Martha Lewis (co-promotor). The project starts April 1st 2025.
The public summary of the project is as follows. AI-models appear to be rapidly developing human-like intelligence. For both scientists and the broader public, an urgent question is “How smart is AI currently and how intelligent will it become?”. However, we do not know because current methods for evaluating intelligence in people are not suitable for AI and vice versa due to inherent differences in learning, memory, and processing between these systems. This project develops the necessary methods to study how smart AI-models are compared to people, now and in the future, and sheds light on how to safely utilize AI in our daily lives.
This PhD project has three objectives:
(1) Build an app containing children’s games that assesses fluid intelligence accessible to both humans and AI.
(2) Develop psychometric methods to reliably and validly compare children’s and AI-models’ developing fluid intelligence.
(3) Evaluate whether leading theories of human developing intelligence, or a new alternative theory, can account for emergent AI cognitive capabilities.

The PhD student is responsible for helping achieve these three objectives. They will collaborate with the supervisors, fellow PhD students, postdocs and international colleagues associated with the CreAI Lab (creailab.net).
The research tasks will include data collection with children and AI-models; developing psychometric methods to reliably and validly compare children’s, adults' and AI-models’ fluid intelligence across a series of cognitive tasks; and conducting cross-sectional and longitudinal data analysis (e.g., item response theory, latent change score models) comparing children’s and AI-models’ developing intelligence.
Teaching is limited to 5% of the contracted hours, by assisting in courses and supervising (bachelor) thesis students.
A promising candidate has proven affinity with cognitive AI research, experience with data collection with children (in Dutch) and AI-models, psychometrics – especially in dealing with violations of measurement invariance, as well as extensive computer programming experience in R and Python.
Given that the project lies at the intersection of psychology, cognitive science, and AI, a successful candidate has an interest and the capacity to work and interact in a multidisciplinary team.
Your experience and profile:
• A master's degree with specialization in psychological methods or a related discipline.
• Experience coding in R and Python (or related computer programming languages).
• Excellent written and spoken command of both English and Dutch.
The position concerns temporary employment of 38 hours per week. The initial employment is for one year. Following a positive assessment and barring altered circumstances, this term will be extended for a total duration of 4 years, which should result in the conferral of a doctorate. We will put together a curriculum which will also include the opportunity to attend training courses and both national and international events.
For this position the University Job Classification profile 'promovendus' applies.
Your salary will be €3.059 gross per month in the first year and will increase to €3.881 in the final year, based on full-time employment and in keeping with the Collective Labour Agreement of Dutch Universities. We additionally offer an extensive package of secondary benefits, including 8% holiday allowance and a year-end bonus of 8.3%.
The UvA offers excellent possibilities for further professional development and education.
What else do we offer
• a position in which initiative and input are highly valued
• an enthusiastic and warm team that is open to new colleagues
• an inspiring academic and international working environment in the heart of Amsterdam.
