The role of personal data value, culture and self-construal in online privacy behaviour
2021
Personal data is ubiquitous in the digital world, can be highly valuable in aggregate, and can lead to unintended intrusions for the data creator. However, individuals’ expressions of concern about exposure of their personal information are generally not matched by their behavioural caution. One reason for this mismatch could be the varied and intangible value of personal data. We present three studies investigating the potential association between personal data value and privacy behaviour, assessing both individual and cross-cultural differences in personal data valuation, comparing collectivist and individualistic cultures. Study 1a, using a representative UK sample, found no relationship between personal data value and privacy behaviour. However, Study 1b found Indian (collectivist) participants’ privacy behaviour was sensitive to personal data value, unlike US (individualist) participants. Study 2 showed that in a UK sample, privacy behaviour was sensitive to personal data value but only for individuals who think of themselves as more similar to others (i.e., self-construe as similar, rather than different). We suggest those who prioritise group memberships are more sensitive to unintentional disclosure harm and therefore behave in accordance with personal data valuations—which informs the privacy concern-behaviour relationship. Our findings can suggest approaches to encourage privacy behaviours.

Social orienting in gaze leading: a mechanism for shared attention

Here, we report a novel social orienting response that occurs after viewing averted gaze. We show, in three experiments, that when a person looks from one location to an object, attention then shifts towards the face of an individual who has subsequently followed the person's gaze to that same object. That is, contrary to ‘gaze following’, attention instead orients in the opposite direction to observed gaze and towards the gazing face. The magnitude of attentional orienting towards a face that ‘follows’ the participant's gaze is also associated with self-reported autism-like traits. We propose that this gaze leading phenomenon implies the existence of a mechanism in the human social cognitive system for detecting when one's gaze has been followed, in order to establish ‘shared attention’ and maintain the ongoing interaction.

We tested whether gaze direction identification of individual faces can be modulated by prior social gaze encounters. In two experiments, participants first completed a joint-gaze learning task using a saccade/antisaccade paradigm. Participants would encounter some ‘joint-gaze faces’ that would consistently look at the participants saccade goal before participants looked there (Experiment
1
) or would follow the participants gaze to the target (Experiment
2
). ‘Non-joint-gaze faces’ would consistently look in the opposite direction. Participants then completed a second task in which they judged the gaze direction of the faces they had previously encountered. Participants were less likely to erroneously report faces with slightly deviated gaze as looking directly at them if the face had previously never engaged in joint gaze with them. However, this bias was only present when those faces had
looked first
(Experiment
1
) and not when the faces
looked after
participants (Experiment
2
). Comparing these data with gaze identification responses of a control group that did not complete any joint-gaze learning phase revealed that the difference in gaze identification in Experiment
1
is likely driven by a lowering of direct gaze bias in response to non-joint-gaze faces. Thus, previous joint-gaze experiences can affect gaze direction judgements at an identity-specific level. However, this modulation may rely on the socio-cognitive information available from viewing other’s initiation behaviours, especially when they fail to engage in social contact.

To facilitate social interactions, humans need to process the responses that other people make to their actions, including eye movements that could establish joint attention. Here, we investigated the neurophysiological correlates of the processing of observed gaze responses following the participants’ own eye movement. These observed gaze responses could either establish, or fail to establish, joint attention. We implemented a gaze leading paradigm in which participants made a saccade from an on-screen face to an object, followed by the on-screen face either making a congruent or incongruent gaze shift. An N170 event-related potential was elicited by the peripherally located gaze shift stimulus. Critically, the N170 was greater for joint attention than non-joint gaze both when task-irrelevant (Experiment 1) and task-relevant (Experiment 2). These data suggest for the first time that the neurocognitive system responsible for structural encoding of face stimuli is affected by the establishment of participant-initiated joint attention.

Personal information

Personal data is of great commercial benefit and potential sensitivity. However, for the consumers who provide their personal data, doing so comes with potential costs, benefits and security risks. Typically, consumers have the option to consent to the use of personal/sensitive data but existing research suggests consumer choices may only be weakly related to their concerns (the privacy paradox). Here, we examine if the repetitive nature of data requests alters behaviour but not concern, therefore, explaining the divergence. This work is theoretically grounded in ‘Foot in the door’ research in which small initial requests facilitate subsequent larger requests. An initial laboratory study asking for real, personal data demonstrated increased information disclosure at a subsequent request. A second online study replicated the increased information disclosure effect and found no change in associated privacy concern. We find this supports foot-in-the-door as one explanation of the privacy paradox. We suggest ways for businesses and consumers to encourage an acceptable level of disclosure to match personal beliefs for mutual trust and benefit.

This paper reports on a pilot study that used eye tracking techniques to make detailed observations of item response processes in the OECD Programme for the International Assessment of Adult Competencies (PIAAC). The lab-based study also recorded physiological responses using measures of pupil diameter and electrodermal activity. The study tested 14 adult respondents as they individually completed the PIAAC computer-based assessment. The eye tracking observations help to fill an 'explanatory gap' by providing data on variation in item response processes that are not captured by other sources of process data such as think aloud protocols or computer-generated log files. The data on fixations and saccades provided detailed information on test item response strategies, enabling profiling of respondent engagement and response processes associated with successful performance. Much of that activity does not include the use of the keyboard and mouse, and involves 'off-screen' use of pen and paper (and calculator) that are not captured by assessment log-files. In conclusion, this paper points toward an important application of eye tracking in large-scale assessments. This includes insights into response processes in new domains such as adaptive problem-solving that aim to identify individuals' ability to select and combine resources from the digital and physical environment.

Urban political ecologies of housing and climate change
2017
Urban authorities and a range of private and civil society actors have come to view housing as a key arena in which to address climate change whilst also pursuing wider social, economic and environmental objectives. Housing has been a critical area for urban studies, but often considered in sectoral terms and work on urban responses to climate change has followed this positioning. By contrast, an Urban Political Ecology (UPE) perspective would position housing in more integrated terms as part of the metabolism of the city. Yet so far there has been relatively little written in UPE about either housing or climate change. This paper therefore seeks to bring UPE into dialogue with the emergent literature focused on governing climate change through housing. It does so through a detailed study of the 'Retrofit Philly \"Coolest Block\" Contest'. We argue that this contest highlights the ways climate change is changing the way housing is embedded in the circulations of the city, pointing to changes in who is governing housing, how housing is being governed and who is able to access the benefits of (climate change-branded) action on housing.

Justice, neoliberal natures, and Australia's water reforms
2015
Scholars studying the neoliberalisation of nature (and political ecologists more broadly) have been notably concerned with justice, but have underspecified their own conceptions of justice and have failed to seriously question or investigate what kind (or kinds) of justice is actually being pursued in the context of neoliberalism. In this paper, I argue that a more robust treatment of justice is required, building on recent calls for a more reflexive approach to normativity in critical human geography. I make this argument by drawing on a study examining how justice has been mobilised in Australia's neoliberal water reforms, and particularly through a series of semi-structured interviews with water policymakers and industry professionals. I show that the justice being pursued through these reforms is multivalent, but coalesces around an allocative framework I call the 'basic needs plus market' framework. This framework ultimately finds its moral compass in a utilitarian conception of distributive justice, and this utilitarianism both facilitates neoliberalisation and tempers its expression. Understanding neoliberalisation as a means to broader normative ends, I suggest, has considerable potential for both explaining the contradictions and contestations scholars have argued are intrinsic to 'actually existing neoliberalism' and opening up opportunities for productive critique and engagement.
