Replicating and Applying a Neuro-Cognitive Experimental Technique in HCI Research
In cognitive neuroscience the sense of agency is defined as the as the
experience of controlling ones own actions and, through this control, affecting
the external world. At CHI 2012 I presented a paper entitled I did that!
Measuring Users Experience of Agency in their own Actions [1]. This extended
abstract draws heavily on that paper, which described an implicit measure
called intentional binding. This measure, developed by researchers in cognitive
neuroscience, has been shown to provide a robust implicit measure for the sense
of agency. My interest in intentional binding stemmed from prior HCI
literature, (e.g. the work of Shneiderman) which emphasises the importance of
the sense of control in human-computer interactions. The key question behind
the CHI 2012 paper was: can we apply intention binding to provide an implicit
measure for the experience of control in human-computer interactions? In
investigating this question, replication was a key element of the experimental
process.Comment: 4 pages, presented at RepliCHI2013 at ACM CHI 201
Competing or aiming to be average?: Normification as a means of engaging digital volunteers
Engagement, motivation and active contribution by digital volunteers are key requirements for crowdsourcing and citizen science projects. Many systems use competitive elements, for example point scoring and leaderboards, to achieve these ends. However, while competition may motivate some people, it can have a neutral or demotivating effect on others. In this paper we explore theories of personal and social norms and investigate normification as an alternative approach to engagement, to be used alongside or instead of competitive strategies. We provide a systematic review of existing crowdsourcing and citizen science literature and categorise the ways that theories of norms have been incorporated to date. We then present qualitative interview data from a pro-environmental crowdsourcing study, Close the Door, which reveals normalising attitudes in certain participants. We assess how this links with competitive behaviour and participant performance. Based on our findings and analysis of norm theories, we consider the implications for designers wishing to use normification as an engagement strategy in crowdsourcing and citizen science systems
Interaction design and emotional wellbeing
The World Health Organisation has concluded that
emotional wellbeing is fundamental to our quality of
life. It enables us to experience life as meaningful and
is an essential component of social cohesion, peace and
stability in the living environment [21]. This workshop
will bring together a diverse community to consolidate
existing knowledge and identify new opportunities for
research on technologies designed to support emotional
wellbeing. The workshop will examine uses of
technology in mental health settings, but will also
consider the importance of emotional needs in physical
healthcare and wellbeing more generally. The design of
technology to provide social support and to extend
traditional care networks will be key workshop themes
Pupal and Adult Parameters as Potential Indicators of Cottonwood Leaf Beetle (Coleoptera: Chrysomelidae) Fecundity and Longevity
Cottonwood leaf beetle, Chrysomela scripta, pupae from a laboratory colony were weighed and monitored through adult emergence, oviposition, and mortality to determine if correlations existed between various pupal or adult parameters and fecundity or longevity. Forty-three female cottonwood leaf beetles were monitored. Pupal weight was not a good indicator of fecundity, total oviposition events, number of eggs/beetle/day, or adult longevity. In addition, adult weight showed very low correlation with fecundity, adult longevity, total oviposition events, or number of eggs/beetle/day. However, adult weight was a marginal indicator of the number of eggs/beetle/day, and correlated well with adult body length. Adult longevity could be used to predict fecundity
