Are you self-motivated, curious and interested in research? Are you excited to work on a project that is of theoretical and societal significance? Are you interested in researching the linguistic factors that make textual information credible? Consider joining the Language and Communication research group as a PhD student to conduct cutting-edge research at the intersection of text comprehension, language technology and persuasion research.

We are seeking to hire a highly motivated, driven, and talented PhD student to carry out this PhD project in a period of four years. The PhD project is funded by a grant awarded to dr. Marloes van Moort, dr. Karin Fikkers, Prof.dr. Hans Hoeken and Prof.dr. Antal van den Bosch, and will be carried out at the Institute for Language Sciences (ILS), Utrecht University. You will work in an interdisciplinary team with researchers from the fields of cognitive psychology, text comprehension, language technology and persuasion research.

As a PhD candidate ("aio") you can devote 10% of your four-year appointment to non-research related tasks, such as teaching. Note that, given the limited amount of teaching, it is not possible to obtain a University Teaching Qualification (‘BKO’) during your PhD.

Project description:
In today's information society people are faced with an avalanche of messages, often expressing opposing views. In addition, spreading false or misleading information online has become increasingly prevalent (e.g., disinformation or fake news). Thus, it is crucial that readers are able to distinguish true from false, and meaningful information from misinformation.

In this PhD project you will focus on whether and to what extent linguistic factors influence the credibility of (textual) information. Specifically, you will investigate to what extent being able to process a text smoothly (i.e., processing fluency) affects whether readers find information credible, regardless of whether the message’s content is true or not. In these investigations you will take into account the latest developments in language technology by examining the possible role of Large Language Models such as ChatGPT in generating (in)correct information. Texts produced by such LLMs provide an interesting case, as the way these programmes are designed allows them to generate texts that are often very easy to process. They produce texts by “choosing” the word that is most likely at a certain position. Precisely because that word is likely, readers will also expect it and the processing process will most likely be smoother.
This PhD project consists of two parts.

  1. The first (language technological) part of the project builds on previous (language technological) research into the linguistic determinants of comprehensibility and focusses on identifying linguistic features that affect the ease of processing or the degree of acceptance of correct and incorrect information.
  2. In the second, empirical-experimental part, you will conduct a series of experiments to test to what extent the linguistic features identified in part one actually influence credibility and therefore the acceptance of a message, and to what extent that potential effect is achieved through ease of processing.

You will investigate these processes for both correct and incorrect information and for texts written by humans and text generated by tools such as ChatGPT (or other language models) to test whether the same processes play a role, and if so, whether we utilize these processes in correcting/rectifying misconceptions in readers.

If you are passionate about exploring the complex interactions between linguistic factors and text credibility then we encourage you to apply for this exciting opportunity. You will have the chance to develop your research skills, work with a dynamic team, and make a valuable contribution to the field of text research. Also, there will be plenty of opportunities to add your own twist to the research project.

This PhD position is part of the interdisciplinary UU PhD programme of the Faculty of Humanities, funded by the administrative agreement (‘bestuursakkoord’) between the Ministry of OCW and the universities.


General requirements:

  • A (research) MA degree (or equivalent) in Communication and Information Science, Psychology, Educational Science, (Computational) Linguistics, Cognitive science, Artificial Intelligence or a related discipline in hand by the starting date;
  • Demonstrable knowledge in at least one of the following areas: text comprehension, language technology, persuasion, fake news, misinformation;
  • High proficiency in academic English and high proficiency in Dutch;
  • Ability to work both as an independent researcher and as a team member with an empirical research focus and knowledge of, or the willingness to learn, specific quantitative and qualitative research methods, including (but not limited to) corpus analyses and experiments;
  • Affinity with interdisciplinary research and ability to meet deadlines;
  • Strong organizational, social and communication skills;
  • Experience with quantitative analysis using statistical software (e.g., Stata, R, Python, SPSS, JASP);
  • It would be an advantage to have experience with corpus analysis, programming (e.g. Python, Psychopy, E-prime) and/or Large Language Models (e.g. Huggingface).


You will be offered a temporary position (1.0 FTE), initially for one year with an extension to a total of four years upon a successful assessment in the first year, and with the specific intent that it results in a doctorate within this period. The gross salary ranges between €2541 in the first year and €.3247 in the fourth year of employment (scale P according to the Collective Labour Agreement Dutch Universities) per month for a full-time employment. Salaries are supplemented with a holiday bonus of 8% and a year-end bonus of 8.3% per year.

In addition, Utrecht University offers excellent secondary conditions, including an attractive retirement scheme, professional development, (partly paid) parental leave, sports and flexible employment conditions (multiple choice model).
