Funding: The studentship consists of an annual stipend of £16,062, plus £5,360 to cover home tuition fees, for 36 months.
Application deadline: 5th December 2022 (interviews to take place w/c 12th December).
Start date: January 2023.

Location: Colchester Campus
Based in: Department of Psychology
This funded PhD studentship aims to understand how people use reflection when solving word problems.
This PhD studentship is funded as a part of the Leverhulme Trust grant “On the purpose of cognitive reflection” awarded to the listed supervisors. The role of the PhD student will be to prepare, conduct and publish the proposed research.
The student will join a vibrant department with an active cohort of doctoral students, and supportive team of academics, administrators, and technicians.
We welcome applications from candidates with a background in psychology or related disciplines.
Many would agree that the ability of humans to engage in reflection is what distinguishes us from other animals. However, less agreement exists on why we acquired the ability to reflect and what its main purpose is.
Traditionally, we view the purpose of reflection as to secure better knowledge and increase accuracy to solve problems and make better decisions. But, some scientists have proposed recently that its main purpose is social—to create socially acceptable justifications of the desired, intuitively generated solutions and decisions to sway others efficiently towards your solutions and decisions.
While we can easily imagine, for instance, a business person thinking hard about the reasons that would persuade a potential customer to buy their product, it is harder to imagine a person thinking hard about a word problem only to come up with justifications for their intuitive solutions to the problem to sway others towards their solution. We will test this counter-intuitive suggestion in this proposal.
Specifically, we will investigate the purpose of reflection in solving verbal problems explicitly designed to measure cognitive reflection. These problems prompt appealing but incorrect responses; for example: “A bat and a ball cost £1.10 in total. The bat costs £1.00 more than the ball. How much does the ball cost?” The appealing answer to this problem is that the ball costs 10 pence. However, this is wrong, and the correct answer is 5 pence.
Traditionally, it was believed that when solving these problems, people first generate a wrong but intuitively appealing answer, and then they correct their wrong intuitions during the reflective stage of reasoning. Thus, this analytical inference account assumes that the main purpose of reflection is to achieve accuracy.
In contrast, recent evidence suggests that people might be able to generate most of the correct answers already intuitively, and reflection serves a different purpose. Thus, this intuitive inference account assumes that the main purpose of reflection lies somewhere else, for instance, in our ability to justify (not correct) our intuitions. These two principal accounts explain how people arrive at the correct answer and map clearly on two different views of the purpose of reflection.
Building on these ideas, we aim to achieve three objectives.
First, we aim to identify whether people come up with the correct solutions to the cognitive reflection problems cueing appealing but incorrect responses intuitively or after deliberation. Do people generate most of the correct responses already during the initial intuitive reasoning stage or only after some deliberation?
Second, we aim to identify the quality of people’s justification for their answers before and after deliberation. Do people justify their answers much better after deliberation? Determining when the correct solution and its justification are generated will shed more light on the function of cognitive reflection.
Third, we aim to determine how fast, intuitive reasoning can account for the predictive power of the ability to solve cognitive reflection problems. Do strong correlation patterns emerge already between intuitively generated correct answers to cognitive reflection problems and various epistemic beliefs, judgments and decision-making? This will help us determine which function of cognitive reflection drives the prediction of a wide array of constructs associated with the correct answers to cognitive reflection problems.
