Designing for Sustained Motivation: A Review of Self-Determination Theory in Behaviour Change Technologies
Recent years have seen a surge in applications and technologies aimed at
motivating users to achieve personal goals and improve their wellbeing.
However, these often fail to promote long-term behaviour change, and sometimes
even backfire. We consider how self-determination theory (SDT), a metatheory of
human motivation and wellbeing, can help explain why such technologies fail,
and how they may better help users internalise the motivation behind their
goals and make enduring changes in their behaviour. In this work, we
systematically reviewed 15 papers in the ACM Digital Library that apply SDT to
the design of behaviour change technologies (BCTs). We identified 50
suggestions for design features in BCTs, grounded in SDT, that researchers have
applied to enhance user motivation. However, we find that SDT is often
leveraged to optimise engagement with the technology itself rather than with
the targeted behaviour change per se. When interpreted through the lens of SDT,
the implication is that BCTs may fail to cultivate sustained changes in
behaviour, as users' motivation depends on their enjoyment of the intervention,
which may wane over time. An underexplored opportunity remains for designers to
leverage SDT to support users to internalise the ultimate goals and value of
certain behaviour changes, enhancing their motivation to sustain these changes
in the long term.Comment: Submitted to the Interacting with Computers (IwC) special issue on

Third Party Tracking in the Mobile Ecosystem
Third party tracking allows companies to identify users and track their
behaviour across multiple digital services. This paper presents an empirical
study of the prevalence of third-party trackers on 959,000 apps from the US and
UK Google Play stores. We find that most apps contain third party tracking, and
the distribution of trackers is long-tailed with several highly dominant
trackers accounting for a large portion of the coverage. The extent of tracking
also differs between categories of apps; in particular, news apps and apps
targeted at children appear to be amongst the worst in terms of the number of
third party trackers associated with them. Third party tracking is also
revealed to be a highly trans-national phenomenon, with many trackers operating
in jurisdictions outside the EU. Based on these findings, we draw out some
significant legal compliance challenges facing the tracking industry.Comment: Corrected missing company info (Linkedin owned by Microsoft). Figures

Computers as Bad Social Actors: Dark Patterns and Anti-Patterns in Interfaces that Act Socially
Technologies increasingly mimic human-like social behaviours. Beyond
prototypical conversational agents like chatbots, this also applies to basic
automated systems like app notifications or self-checkout machines that address
or 'talk to' users in everyday situations. Whilst early evidence suggests
social cues may enhance user experience, we lack a good understanding of when,
and why, their use may be inappropriate. Building on a survey of
English-speaking smartphone users (n=80), we conducted experience sampling,
interview, and workshop studies (n=11) to elicit people's attitudes and
preferences regarding how automated systems talk to them. We thematically
analysed examples of phrasings/conduct participants disliked, the reasons they
gave, and what they would prefer instead. One category of inappropriate
behaviour we identified regards the use of social cues as tools for
manipulation. We describe four unwanted tactics interfaces use: agents playing
on users' emotions (e.g., guilt-tripping or coaxing them), being pushy,
`mothering' users, or being passive-aggressive. Another category regards
pragmatics: personal or situational factors that can make a seemingly friendly
or helpful utterance come across as rude, tactless, or invasive. These include
failing to account for relevant contextual particulars (e.g., embarrassing
users in public); expressing obviously false personalised care; or treating a
user in ways that they find inappropriate for the system's role or the nature
of their relationship. We discuss these behaviours in terms of an emerging
'social' class of dark and anti-patterns. Drawing from participant
recommendations, we offer suggestions for improving how interfaces treat people
in interactions, including broader normative reflections on treating users
respectfully.Comment: Accepted paper for the 2024 ACM SIGCHI Conference on

Further Exploring Communal Technology Use in Smart Homes: Social Expectations
Device use in smart homes is becoming increasingly communal, requiring
cohabitants to navigate a complex social and technological context. In this
paper, we report findings from an exploratory survey grounded in our prior work
on communal technology use in the home [4]. The findings highlight the
importance of considering qualities of social relationships and technology in
understanding expectations and intentions of communal technology use. We
propose a design perspective of social expectations, and we suggest existing
designs can be expanded using already available information such as location,
and considering additional information, such as levels of trust and
reliability.Comment: to appear in CHI '20 Extended Abstracts, April 25--30, 2020,

Self-Control in Cyberspace: Applying Dual Systems Theory to a Review of Digital Self-Control Tools
Many people struggle to control their use of digital devices. However, our
understanding of the design mechanisms that support user self-control remains
limited. In this paper, we make two contributions to HCI research in this
space: first, we analyse 367 apps and browser extensions from the Google Play,
Chrome Web, and Apple App stores to identify common core design features and
intervention strategies afforded by current tools for digital self-control.
Second, we adapt and apply an integrative dual systems model of self-regulation
as a framework for organising and evaluating the design features found. Our
analysis aims to help the design of better tools in two ways: (i) by
identifying how, through a well-established model of self-regulation, current
tools overlap and differ in how they support self-control; and (ii) by using
the model to reveal underexplored cognitive mechanisms that could aid the
design of new tools.Comment: 11.5 pages (excl. references), 6 figures, 1 tabl
“I finally felt i had the tools to control these urges”: empowering students to achieve their device use goals with the reduce digital distraction workshop
Digital self-control tools (DSCTs) help people control their time and attention on digital devices, using interventions like distraction blocking or usage tracking. Most studies of DSCTs’ effectiveness have focused on whether a single intervention reduces time spent on a single device. In reality, people may require combinations of DSCTs to achieve more subjective goals across multiple devices. We studied how DSCTs can address individual needs of university students (n = 280), using a workshop where students reflect on their goals before exploring relevant tools. At 1-3 month follow-ups, 95% of respondents still used at least one type of DSCT, typically applied across multiple devices, and there was substantial variation in the tool combinations chosen. We observed a large increase in self reported digital self-control, suggesting that providing a space to articulate goals and self-select appropriate DSCTs is a powerful way to support people who struggle to self-regulate digital device use
Hearing in Color: How Expectations Distort Perception of Skin Tone
Abstract from publication:
Previous research has found that the perceived brightness of a face can be distorted by the
social category of race. Thus, Levin & Banaji (2006) found in a US sample that faces of
identical brightness were perceived to be lighter if they had stereotypical White American
features than if they had Black American features. Here, we present two experiments
conducted in Natal, Brazil, that extend this line of research. Experiment 1 tested if the
brightness distortion effect would generalize to a Brazilian population. Experiment 2 tested if
speech accent would have a similar effect on brightness perception. In Experiment 1, we
found that the brightness distortion effect clearly replicated in the Brazilian sample: faces
with Black racial features were perceived to be darker than faces with White racial features,
even though their objective brightness was identical. In Experiment 2, we found that speech
accent influenced brightness perception in a similar manner: faces were perceived to be
darker when paired with an accent associated with low socio-economic status than when they
were paired with an accent associated with high socio-economic status. Whereas racial
concepts in Brazil are often claimed to be much more fluid compared to the US, our findings
suggest that the populations are quite similar with respect to associations between facial
features and skin tone. Our findings also demonstrate speech accent as an additional source of
category-information that perceptual cognition can take into account when modelling the
world
