Investigating the value of using emotionally intelligent artificial conversational agents to carry out assessments in higher education or healthcare.
Artificial conversational agents can be embodied (physical robots or digital avatars on a screen) or not embodied (chat-bots or digital assistants). Agents may be able to converse but they can also appear ‘empathetic/emotionally intelligent’ when they talk, and in the case of embodied agents they can also deliver non-verbal communication (body language/facial expressions). In the higher education domain, viva assessments (oral examinations) are used frequently to assess candidates on their work and have many benefits for both the student and the assessor. For example, providing: the opportunity to carry out highly personalised/tailored assessment, unique insight into student ability and understanding, probe depth of knowledge, ensure the authenticity of submitted written work, and provide real-time feedback on performance, to name a few. Viva assessments, however, are known to cause anxiety, particularly as a result of the social interaction and in particular face-to-face interaction with an assessor/lecturer, that a traditional viva setting demands. Although there is some evidence in the field of Human-Computer Interaction (HCI) and agent-based interaction research that suggests that interaction with artificial agents can elicit lower levels of anxiety compared with a human equivalent, there is a need to explore the pedagogical value of using intelligent (emotionally intelligent or similar) artificial agents to carry out viva assessments within the higher education domain.
Whilst this advertisement sets the backdrop to the area in which the successful PhD candidate could position their research, there is much scope for tailoring this topic to the successful candidate’s specific knowledge, interests, and skills. Similarly, there is significant scope to explore the use of intelligent conversational agents within the area of healthcare research, for example, exploring the value of using artificial agents in the context of talking therapies (e.g. psychotherapy, psychoanalysis, cognitive behavioural therapy, cognitive analytic therapy), if this is an area that is more in line with the successful candidate’s interests.
Hence, we invite applications from candidates that have an interest in exploring the value of using intelligent conversational agents within the context of higher education or healthcare. It is envisaged that the successful candidate would design, develop, and evaluate a prototype conversational agent (embodied/not embodied, possibly using wizard of oz techniques) and trial it within the chosen higher education/healthcare context.
Candidates should have good software development and prototype design and development skills. Experience of carrying out user-centred research and collecting and analysing both qualitative and quantitative data is also desirable. A good first degree in Computer Science or equivalent is essential.
