Research Paper

Cooperation and gender in hyper-social spaces

© Martí E. Berenguer | FiraTàrrega

Cooperation in hyper-social spaces is highly conditioned by the gender of the interacting individuals. This experiment, carried out at Fira de Tàrrega in 2017, measures the willingness of people to cooperate, pairing them to take part in the prisoner's dilemma game, outdoors and in the context of an artistic performance. This experiment, performed using participatory research and citizen science principles, shed light on how the other’s gender identity is a relevant factor in terms of cooperation and trust. In hyper-social scenarios, individuals show a pro-social behaviour, especially women, who exhibit high levels of cooperation, trust and ability to guess the others’ behaviour. The complete research paper «Gender-based pairings influence cooperative expectations and behaviours» is publicly available in Scientific Reports and co-authored with Anna Cigarini and Josep Perelló.

«Citizen Science in Action» aimed to co-create a citizen science experiment focused on a social concern shared by the community around libraries, for and by library-goers, in three Barcelona municipalities (Granollers, Olesa de Montserrat and Fort Pienc). From this collaborative process emerged the shared concern of access to housing. All the participants formulated and conceptualized an intervention in the public space to collect evidence to answer different research questions. The result was «Jocs per l’Habitatge» («Games for Housing»), an intervention in public spaces which consisted in four days of data collection about different dilemmas that citizens face when citizens and policy-makers intervene in the housing market.

Citizen science practices have been boosted in urban contexts around the world. Participatory efforts include identification of concerns, definition and design of research, collection of data and the proposals of actions that respond to specific concerns with scientific evidence. This event counted on the insights, among others, of Louis Francis (Mapping for change), who talked about environmental actions and air quality, Shannon Dosemagen (Public Lab), who shed light on community science and collective action, and LeeAnne Walters, who explained the experience of the Flint water crisis supply. These were only some of the interesting talks about citizen science and actions that took place at «. The event was organized by OpenSystems members as part of Biennal Ciutat i Ciència and the Citizen Science COST Action 15212.

Social Interactions in a mental health care community

© OpenSystems | Mental Health Day, Lleida

Mental disorders have an enormous impact in our society. In «Quantitative account of social interactions in a mental health care ecosystem: cooperation, trust and collective action» we present the results of a suite of games that allow us to probe into different behavioral traits of the mental health care community role groups by means of citizen science practices. The evidence reinforces the idea of community social capital, with caregivers and professionals playing a leading role. Yet, the cost of collective action is mainly supported by individuals with a mental condition - which unveils their vulnerability. We finally point to the conditions under which cooperation among members of the ecosystem is better sustained, suggesting how virtuous cycles of inclusion and participation can be promoted in a "care in the community" framework. This research paper was co-authored with Anna Cigarini, Josep Perelló and Anxo Sanchez.

Behavioural phenotypes: envious, optimist, pessimist and trustful

© OpenSystems | DAU Festival, Barcelona

Lab-in-the-field experiment in which 541 individuals face four different dyadic games with the aim of establishing general behavioral rules dictating individuals’ actions. By analyzing the observations of these simple social situations using machine learning algorithms, we find that a majority of the subjects conform, with a large degree of consistency, to a limited number of behavioral phenotypes: envious, optimist, pessimist, and trustful. The complete results are publised in Science Advances.

This project was part of my Engineering Thesis focused on the design and development of a natural user inteface and a tridimensional audio system. The thesis was based in previous works in human computer interaction and audio processing. The final artifact creates a sound experience by means of a system that reacts in real-time to the fiducials placed on a table-top user interface. Each fiducial corresponds to a particular sound represented in a tridimensional environment created on a natural user interface working with TUIO protocols.
