Projective testing of diurnal collective emotion

Abstract

Projective tests are personality tests that reveal individuals' emotions (e.g., Rorschach inkblot test). Unlike direct question-based tests, projective tests rely on ambiguous stimuli to evoke responses from individuals. In this paper we develop one such test, designed to be delivered automatically, anonymously and to a large community through public displays. Our work makes a number of contributions. First, we develop and validate in controlled conditions a quantitative projective test that can reveal emotions. Second, we demonstrate that this test can be deployed on a large scale longitudinally: we present a fourweek deployment in our university's public spaces where 1431 tests were completed anonymously by passers-by. Third, our results reveal strong diurnal rhythms of emotion consistent with results we obtained independently using the Day Reconstruction Method (DRM), literature on affect, well-being, and our understanding of our university's daily routine.

Motivating participation and improving quality of contribution in ubiquitous crowdsourcing

“…Alternatively, a passive approach of crowdsourcing tasks to workers is to embed public displays into a physical space and leveraging workers' serendipitous availability. Crowdsourcing using public displays requires little effort from the worker to contribute [19,24], lowering the barriers to contribution from a workers' perspective by minimising the initial effort. Furthermore, it allows for a geofenced and more contextually controlled crowdsourcing environment [24], thus enabling targeting certain individuals [19,20], leveraging people's local knowledge [21,28] or simply reaching an untapped source of potential workers [27,29].…”

Situated crowdsourcing using a market model

“…A second challenge for situated crowdsourcing is managing the influx of workers' contributions, and specifically the need for contributions at a particular geographic location or a time of day [9]. How can those be encouraged, given that altruism and intrinsic motivation are challenging to manipulate precisely [7]?…”

Task Routing and Assignment in Crowdsourcing based on Cognitive Abilities

“…While situated crowdsourcing may be better suited for "local" tasks [27], it has also been shown to be effective with typical crowdsourcing tasks that can be seen in online labour markets [26]. While some situated crowdsourcing deployments do not track workers, making it impossible to assign task based on an individual's cognitive abilities [18,20,27], others have tracked individual workers, such as Bazaar, a situated crowdsourcing market that had user accounts, a virtual currency and rewards [26]. Here, as with online crowdsourcing platforms, having an initial cognitive assessment stage could be beneficial.…”
