A nod in the wrong direction : Does nonverbal feedback affect eyewitness confidence in interviews?
Eyewitnesses can be influenced by an interviewer's behaviour and report information with inflated confidence as a result. Previous research has shown that positive feedback administered verbally can affect the confidence attributed to testimony, but the effect of non-verbal influence in interviews has been given little attention. This study investigated whether positive or negative non-verbal feedback could affect the confidence witnesses attribute to their responses. Participants witnessed staged CCTV footage of a crime scene and answered 20 questions in a structured interview, during which they were given either positive feedback (a head nod), negative feedback (a head shake) or no feedback. Those presented with positive non-verbal feedback reported inflated confidence compared with those presented with negative non-verbal feedback regardless of accuracy, and this effect was most apparent when participants reported awareness of the feedback. These results provide further insight into the effects of interviewer behaviour in investigative interviewsPeer reviewedFinal Accepted Versio
Evaluation Factors for Multi-Stakeholder Broadband Visual Communication Projects
This paper presents a summary of multifaceted
evaluation factors that we have
identified through our research with
Broadband Visual Communication (BVC)
projects involving multiple stakeholders. The
main benefit of these evaluation factors is
that they provide a general evaluation
framework for multiple stakeholder projects.
The factors are social infrastructure,
technical infrastructure, physical space,
interaction style and content
Moving together: the organisation of non-verbal cues during multiparty conversation
PhDConversation is a collaborative activity. In face-to-face interactions interlocutors have mutual
access to a shared space. This thesis aims to explore the shared space as a resource for coordinating
conversation. As well demonstrated in studies of two-person conversations, interlocutors
can coordinate their speech and non-verbal behaviour in ways that manage the unfolding conversation.
However, when scaling up from two people to three people interacting, the coordination
challenges that the interlocutors face increase. In particular speakers must manage multiple listeners.
This thesis examines the use of interlocutors’ bodies in shared space to coordinate their
multiparty dialogue.
The approach exploits corpora of motion captured triadic interactions. The thesis first explores
how interlocutors coordinate their speech and non-verbal behaviour. Inter-person relationships
are examined and compared with artificially created triples who did not interact. Results demonstrate
that interlocutors avoid speaking and gesturing over each other, but tend to nod together.
Evidence is presented that the two recipients of an utterance have different patterns of head and
hand movement, and that some of the regularities of movement are correlated with the task structure.
The empirical section concludes by uncovering a class of coordination events, termed simultaneous
engagement events, that are unique to multiparty dialogue. They are constructed using
combinations of speaker head orientation and gesture orientation. The events coordinate multiple
recipients of the dialogue and potentially arise as a result of the greater coordination challenges
that interlocutors face. They are marked in requiring a mutually accessible shared space in order
to be considered an effective interactional cue.
The thesis provides quantitative evidence that interlocutors’ head and hand movements are
organised by their dialogue state and the task responsibilities that the bear. It is argued that a
shared interaction space becomes a more important interactional resource when conversations
scale up to three people
Interpreting in a community of practice : a sociolinguistic study of the signed language interpreter's role in workplace discourse
This thesis explores the role of signed language interpreters (SLIs) in the workplace, a
setting which presents challenges in terms of role, boundaries and interaction with
deaf and hearing employees. The key research aims were to determine how primary
participants understand the role of the SLI, and how this influences the dynamics of
everyday interaction. Specific attention was paid to norms of discourse and shared
repertoires within a workplace Community of Practice (CofP). A detailed description
of the interpreting process was thus generated, enabling a deeper appreciation of
workplace dialogue where the SLI is an active third participant.
The research takes a linguistic ethnographic approach to examining signed language
interpreting within the workplace. Data were collected through the use of
questionnaires, practitioner journals, video-recorded interpreted interaction gathered
in workplace settings, and video playback interviews.
Findings show that the SLI has a considerable impact on the ways in which members
of a CofP interact, specifically in relation to small talk, humorous exchanges and
participation in the collaborative floor. The SLI’s management of these aspects of
workplace discourse influences the extent to which collegial relations can be
established between employees. These findings have significance in relation to the
training and education of SLIs, as well as their practice in this domain. The findings
also demonstrate the need for all participants to re-evaluate their understanding of
interpreted workplace discourse, moving towards a collaborative approach

The role of perceived proximity in video-mediated communication
As technology for remote communication continues to advance and become more widespread, there is a need for research to attempt to understand the manner in which such technology may most suitably support human communication. This thesis describes a series of experiments which investigated the role of proximity within video-mediated communication.
Proximity is one of the most fundamental forms of non-verbal communication used in a face-to-face interaction. Even subtle changes in interpersonal positioning are rich in information which people use to attempt to regulate the behaviour of themselves and others. At present it is unknown whether this type of non-verbal communication is preserved in video-mediated interactions. The aim of the present research project was to investigate whether impressions of proximity could be conveyed across a video link. In addition the research attempts to illuminate the physical parameters which may underpin the perception of proximity and to explore the impact upon users that any changes in perceived proximity may cause.
The research uses a wide range of approaches to study the potential impact of proximity including analyses of the structure and content of dialogue, objective and subjective task outcome measures. The research demonstrates that perceptions of proximity can exist in a video-mediated environment and when they do, they can lead to differences in the communication behaviour of individuals communicating across a video link. It is found that when participants interact with a remote interlocutor who appears to be close, they tend to be more interactive. The research goes on to investigate the perceptual basis behind this effect and also considers how this relates to other variables which are known to affect communication, most notably familiarity
Non-Verbal Communication Analysis in Victim-Offender Mediations
In this paper we present a non-invasive ambient intelligence framework for
the semi-automatic analysis of non-verbal communication applied to the
restorative justice field. In particular, we propose the use of computer vision
and social signal processing technologies in real scenarios of Victim-Offender
Mediations, applying feature extraction techniques to multi-modal
audio-RGB-depth data. We compute a set of behavioral indicators that define
communicative cues from the fields of psychology and observational methodology.
We test our methodology on data captured in real world Victim-Offender
Mediation sessions in Catalonia in collaboration with the regional government.
We define the ground truth based on expert opinions when annotating the
observed social responses. Using different state-of-the-art binary
classification approaches, our system achieves recognition accuracies of 86%
when predicting satisfaction, and 79% when predicting both agreement and
receptivity. Applying a regression strategy, we obtain a mean deviation for the
predictions between 0.5 and 0.7 in the range [1-5] for the computed social
signals.Comment: Please, find the supplementary video material at:
