Abstract
One intellectual problem where collaboration can be helpful is coming up with a quantitative judgment under uncertainty. The common consensus among scholars and researchers, though, is that people generally fail to fully realize the advantage of having plural minds. The aim of the present work is to increase our understanding of psychological and social mechanisms that allow interacting individuals to combine their uncertain knowledge into a judgment, and the causes of collective benefit and collective failure in this process.
The present work addresses collective judgment as an "information integration" problem in analogy with the process of multi-sensory integration that takes place within the brain (Ernst & Bülthoff, 2004), following the original approach suggested by Bahrami et al. (2012a). It extends existing research on two lines. First, it addresses the process of inter-individual information integration under conditions implying a different degree of structural overlap in the individually available information. The second novel aspect is the focus on non-verbal modes of interaction via a shared environment.
The thesis includes two empirical studies, each consisting of a series of behavioral experiments that investigate how environment-mediated interactions can support the process of inter-individual information integration under conditions of individual access to redundant and complementary information. The two studies address two conceptually different processes of inter-individual information integration: individual judgment revision and joint judgment formation.
The first study investigates how indirect interactions via a shared environment can help individuals to improve their perceptual judgments by observing another's judgments. The main finding is that whether people can properly integrate observable information in the environment produced by another individual depends on their uncertainty about their own judgment. Crucially, when their own uncertainty is high, people do not discriminate between information of high and low
quality in another's judgment. This leads to underperformance in the potentially most beneficial conditions - the ones where people have access to complementary information.
The second study investigates how well pairs of participants can coordinate their joint judgment by means of interactions via a shared environment. It addresses the interplay between feedback on accuracy and verbal communication under conditions of simultaneous access to complementary and redundant visual information. Under conditions of access to redundant information, availability of feedback on accuracy turns out to be critical: without it interactions do not lead to an improved judgment. Verbal communication does not seem to play a crucial role, but it is helpful under conditions of access to complementary information. Furthermore, in the latter situation, a reliable collective benefit from interaction can be obtained in the absence of verbal communication, of feedback, or both.
The reported studies have three major implications. First, they suggest that in a situation of collective judgment in a shared environment reliable collective benefits from interaction can be obtained without verbal communication. Second, they point to a critical role of a shared agreement on a judgment in this process. Third, they highlight the significance of the factor of structural overlap in individually held information as an important determinant of the amount of collective benefit that collaborators are likely to obtain from social interaction.

How our social network size influences our linguistic skills and linguistic malleability
Does the size of our social network influence how good we are at understanding others or how influenced we are by others' speech patterns? Previous research shows that both infants and adults are better at learning new phonological categories when exposed to multiple speakers compared with only one. In this talk, I'll present converging evidence from individual differences studies, experimental studies, and computational simulations to show that the size of our social network influences our linguistic skills even as adult native speakers, and, in particular, that having a larger social network leads to better comprehension at the phonological and semantic levels. I'll further show that having a smaller social network leads to more malleable representations and use. Thus, aspects of our life-style, such as the size of our social network, can influence how we learn, use, and represent language.
We are looking forward to see you at the talk!
