Introduction

In the fast-paced and high-stakes world of healthcare, every decision can have life-altering consequences. Healthcare professionals, often working irregular hours, are particularly vulnerable to disruptions in their circadian rhythms—the natural, internal process that regulates the sleep-wake cycle. Even with adequate sleep, misalignment of these rhythms can significantly impair cognitive function, decision-making abilities, and error prevention skills. Recognizing these challenges, our research delves into the cognitive effects of shift work and circadian disruption, aiming to enhance the standard of care through improved understanding and innovative solutions.

Objectives

Our research is driven by two primary objectives:

  1. Investigating Cognitive Function Across the Day: We will conduct a comprehensive study to analyze how cognitive processing varies throughout the day for non-shift workers. By employing a rigorous, theory-based methodology, we aim to create a detailed profile of cognitive performance influenced by natural circadian rhythms. This baseline data will then be compared with that of night-shift workers to identify specific impacts of circadian disruption.
  2. Exploring Technological Interventions: In addition to understanding cognitive fluctuations, we aim to explore how technology can either exacerbate or alleviate the negative effects of shift work. Our goal is to design human-centric, accommodating interfaces that serve as cognitive support systems, ultimately reducing error rates and enhancing decision-making quality in healthcare settings.

This project delves into the challenges faced by academics, particularly women and non-binary individuals, who bear the burden of invisible labour in the academy due to increased emotional labour, as well as teaching, service, and administrative tasks, when compared to their male colleagues. These non-research activities often go unnoticed but significantly impact academics’ time for research-related work and career progression.

We propose using Large Language Models as a potential solution. By leveraging LLMs, academics could alleviate some of the invisible labour, allowing them more time for research.

Funded by UCL Research Culture, we are currently undertaking research to explore how LLMs can support academics in managing their invisible labour, ultimately creating a more equitable academic environment. Take part in our survey.

Research Questions

  1. What is the nature of the invisible labour carried out by academics?
  2. What are the current practices of academics using LLMs to support their invisible labour?
  3. How might future tools based on LLMs be designed to support academics with their invisible labour?

What other research are we doing in this space?

We are:

  • developing ResearchComplianceBot that helps academics with the research compliance process ie applying for data protection registration and ethics clearance.
  • exploring how AI can help time-poor academics to conduct peer review

Promoting Inclusive Research Practices

This project aims to make dementia research more inclusive that addresses the challenges experienced by researchers and ethnically-minoritized communities using co-production methods.

We urgently need greater participation of ethnically-minoritized groups in dementia research to understand the reasons for differences in vulnerability and survival, and to provide better interventions. We need to know what barriers ethnically-minoritized communities experience that prevent their participation in dementia research projects. We need to know what barriers researchers experience that prevent them from using inclusive recruitment practices. We need to know how to work collaboratively with multiple stakeholders to improve inclusive recruitment practices.

This project consists of three activities – focus groups, a survey, and a workshop. We will:

  • Conduct focus groups with Black and South Asian community members to identify barriers to participating in dementia research
  • Survey researchers about their current recruitment practices to identify barriers to inclusive recruitment
  • Conduct a workshop, co-designed with community collaborators, that gathers researchers and other stakeholders together, to ideate and co-produce inclusive recruitment practices for dementia research

The modern workplace often places demands on workers to quickly learn and apply new practices in their workflow to maintain productivity. One of the easiest ways to learn about best practices and solutions to common problems at work is via colleagues, particularly when using complex software such as spreadsheets, where expertise is essential to reduce the likelihood of errors. Motivating workers to make their expertise visible and to engage in knowledge sharing is crucial for such interactions to occur, however, current research offers limited perspectives on the experience and motivations of knowledge providers.

Focusing on the context of the spreadsheet, this project aims to develop our understanding of motivational barriers to knowledge sharing behaviours among workers, and then to develop and test interventions which could support workers to engage in more effective knowledge sharing behaviours to improve learning within their community.

Digital technology for neurodiverse students

Exploring Accessibility and digital system support for neurodivergent students

An AI generated image of a student looking distressed sat in front of their laptop

Blended learning has become a mainstream learning experience for many universities, including UCL, during the COVID-19 pandemic. While blended learning has received much attention over the years, particularly in the area of education, we still know little about how people with disabilities engage in blended learning from their homes and what access means in this context.

To understand and rethink accessibility in blended learning, we proposed a programme of study of blended learning practices of neurodivergent students who have Autism Spectrum Disorder, Attention Deficit Hyperactivity Disorder, learning disabilities (e.g., dyslexia) and psychosocial disabilities (e.g., anxiety, depression).  To understand the impact of university digital systems on neurodivergent students, we conducted an interview study. Led by a neurodivergent researcher, this study involved semi-structured interviews with 11 neurodivergent students at UCL. These students, diagnosed with ADHD, autism, or both, shared their experiences and challenges in navigating university digital platforms.

The interviews were designed to be open-ended, allowing students to discuss not just their difficulties, but also their coping strategies and suggestions for improvement.

We used a thematic analysis approach to dive deep into their narratives, identifying common themes and unique insights. By centering the voices of neurodivergent students, our goal was to uncover the real-world impacts of these systems and to highlight practical changes that could make a significant difference in their academic lives. The analysis revealed three key themes:

  • Neurodivergence in academia is not experienced as advantageous, but as an invisible disability}: Participants reported various symptoms of their neurodivergence that impacted academic work, relationships, self-esteem, and more. While there is a common perception of neurodivergent “superpowers,” neurodivergent traits were described as leading to negative feelings, mental health challenges, and worse symptoms.
  • Complex digital workflows trigger symptoms, provide negative user experiences, and impact learning}: Excess user workload emerged as a major concern, encompassing both physical and mental workload. Participants highlighted challenges related to limited integration of systems, number of steps in sequences of interaction, and interaction issues related to lack of simplicity, low intuitiveness, low consistency, and automation. Visual features, customization, and video-related elements also influenced user experiences. The digital systems were reported as triggering symptoms, such as procrastination and emotional dysregulation, negatively affecting academic progress. Login and password systems were a particular source of frustration, demanding urgent attention for improvement.
  • Students implement coping strategies to help them manage their personal and academic experiences: Participants shared their systems for managing their experiences better, including digital tools, physical items, creating a sense of urgency, and accountability buddies. Acknowledging and integrating these strategies into system design has potential for fostering a more supportive environment.

In recent years, new data protection laws have put more responsibilities on researchers covering how we gather, store and process participant data. Many researchers find these requirements confusing and it’s easy to become overwhelmed with the sheer amount of legalese one has to read to truly understand data protection laws and its practicalities.

At the same time, researchers have to obtain ethics approval from their institution and make sure that their project complies with any associated requirements.

This is why we are designing a tool called Research Compliance Buddy. This tool will guide researchers as they fill in applications to register their research with the Data Protection Team and the relevant Ethics Committee. It will help them decide which aspects of applications are relevant to them and which are not, to quickly understand jargon, and guide them directly to the information they need to read to best plan their particular type of research.

We have conducted semi-structured interviews with a diverse group of researchers within the Division of Psychology and Language Sciences at UCL. The data collected during these interviews has been analysed and is guiding the first stage of the design of a chatbot.

Nearly 500 participants contributed to our research on remote working

In spring 2020, an unprecedented number of people suddenly moved to remote working, many of them with little to no previous experience of working from home. This happened as a result of the nationwide lockdown restrictions taking place in many countries, in response to the Covid-19 pandemic. 

From the early days of these lockdowns, we studied that impact that the shift to home-working has had on people who previously worked in offices. So far, we have surveyed nearly 500 participants from the UK and beyond, and provided them with personalised work-life-balance recommendations. We also conducted follow-up interviews with 25 respondents.

This data collection exercise allowed us to achieve an in-depth understanding of the problems that new remote workers are faced with. Some of the most common included:

  • A lack of distinction between work and personal time
  • Back and neck pain and other physical problems due to increased sedentary time
  • Loss of opportunity to relax, exercise and disconnect during the commute
  • Working in long blocks of time, without the breaks that used to happen naturally while working in the office
  • Loss of the many opportunities for physical activity during the workday, like going out to buy lunch or walking to a photocopier

In sum, we found that, rather than being more relaxed while working from home, many people worked longer hours, with few breaks. The situation was particularly challenging for those with caring responsibilities, who found themselves in an endless marathon of work tasks and home duties, with little to no rest.

Your responses helped us create eWork Remote Work Radio

Based on these findings, we set out to design an accessible online tool that could be widely used by home workers and help them take more breaks during their workdays. When working from home, away from one’s colleagues, it can be easy to forget to take breaks, or even to feel like we should always be online and available. However, taking breaks throughout the day is crucial not only for achieving a better work-life balance but also for physical health, as stepping away from the desk on a regular basis helps prevent excessive periods of sitting which can be associated with negative health outcomes.

This is why we created eWork Remote Work Radio – a browser app that uses music to help you balance periods of work and periods of rest. You can help us trial this app simply by creating an account and using the app when you work, for as long as you wish.

Leveraging AI to Overcome the Academic Peer Review Crisis

A poster presented at CHIWORK2024 by Shiping Chen. The headlines reads "Using AI in reviewing can significantly reduce the workload involved in drafting reviews and making academic judgements. But there needs to be smooth collaboration workflows and effective data protection measures in review tools"

In this project we focus on alleviating the peer review crisis in academia. With an increasing number of submissions and a limited number of reviewers, reviewers are becoming overburdened, leading to delays in the review process due to a shortage of reviewers. This research explores using AI tools, such as ChatGPT, to support reviewers by reducing their workload and improving efficiency without compromising the quality of reviews.

The project involves qualitative studies to understand the needs and demands of both reviewers and authors. The initial study examined how reviewers conduct peer reviews, identifying key challenges including iterative interactions with authors, learning how to review, review complexity, lack of training, and workload issues. Another study explored authors’ requirements and attitudes, emphasizing the need for good feedback, optimism about AI, concerns about trust, ethical considerations, and the impact of AI on review processes.

The research also includes an experiment using AI (ChatGPT) to reduce reviewers’ workload and enhance review quality. Reviewers perceived both benefits and challenges, such as saving time, providing different perspectives, and improving confidence, while also facing issues like initial setup time and integration with current workflows. The project underscores the necessity of effective collaboration workflows and robust data protection measures for implementing AI tools in the review process.

eWorkLife: Remote Working during COVID19 lockdowns

eWorkLife was a project that ran from 2020 in response to the sudden switch to remote working that was brought about by the COVID-19 pandemic.

We designed a self-reflection tool which aimed to help workers understand their remote working needs and provided personalised recommendations. This tool took the form of a brief survey, which included some open self-reflection questions and some validated surveys that were used to both help workers reflect on their work practices and provide recommendations to strategies they could adopt to help them adapt.

Our 3 step process

  1. Before you start, take some time to reflect on your work-life balance and what is it exactly you would like to improve. You can spend as much time as you want on this activity. Don’t know where to start? Click here to take part in our research project – we will guide you through a self-reflection exercise (10 mins) and provide you with guidance as to which strategies are most likely to work for you
  2. Select one or two strategies to start with and see how you get on. Remember, your time = your rules. If something doesn’t work for you, you can always revert back to old habits or try out new strategies. Click here to find an overview of the evidence-based strategies that can help you stay productive while working from home
  3. We know from psychological research that goal setting is really important in terms of changing a behaviour. A bit like setting an objective, it’s important to choose a clear and measurable goal. In order to help you stick to your new goal, we recommend you write down what you intend to try. You can also decide to share your commitment on social media, or just by talking to friends, family and/or colleagues. Keeping track of how are you going, and what is working, or not working is really important. Also, you will find that as time goes by, or situations change, you might want to revisit your strategies. Don’t be hard on yourself if you don’t achieve your goal. If that happens, set a more realistic goal and start again. It’s best to set small achievable goals than lots of different ones. Most importantly, make sure you give yourself a reward when you have achieved your goal! Those taking part in our research project receive additional support with setting goals to change their digital behaviours.

Physical Activity during Lockdown

We were interested in how much physical activity people were engaging in – after the move to remote working erased the need to commute, the gyms closed and, for a period of time, even going out to exercise outside was only allowed once per day. We also wanted to understand the role of digital technology in helping people stay active during the lockdown.

We created a Physical Activity survey that was distributed on social media and through newsletters at University College London. The initial survey attracted a total of 390 participants who told us about their physical activity habits: how much time they spent exercising, commuting and sitting – before and during the lockdown and at the start of the survey, in May 2020.

We then sent out four weekly follow-up surveys, so that each week participants could tell us about the changes in their physical activity as well as their motivations and experiences of using technologies aimed to support activity, such as apps, online classes or step trackers. A total of 126 participants completed all five surveys.

We found that people who used digital activity trackers during lockdown demonstrated an increase in vigorous physical activity. This suggests that a robust exercise regime can be maintained even when access to gyms and classes is restricted and using digital activity trackers may facilitate it. On the other hand, we did not find the use of technology to be related with levels of sedentariness during lockdown. Moreover, although many people became more aware of the importance of physical activity during lockdown, problems with motivation and injury resulting from rapid changes in exercise routine, posed a challenge to staying physical active.

Citizen Cyberlab and Citizen Science

citizen cyberlab logo

An increasing number of research projects rely on data provided by citizen scientists and many of these projects collect personal information about the citizen. The Citizen Cyberlab project researched and evaluated on-line collaborative environments and software tools that stimulate creative learning in the context of Citizen Cyberscience. Beyond helping scientists execute laborious tasks, Citizen Cyberscience projects enable citizens to learn about science and take part in the more creative aspects of research. Little is known about the learning and creativity processes stimulated by such projects, even though millions of volunteers participate. Even less is known about how to optimize those processes.

In addition, we know very little about why a citizen scientist would decide to participate in a project or why they would decide to disclose or withhold their data. With data protection becoming one of the most socially salient issues and the focus of a recent legislative overhaul, it is important to understand the complexities of human behaviour in voluntary disclosure scenarios.
