Gossip and Reputation in Natural Societies and Artificial Settings
Francesca Giardini, Central European University
Date: Wednesday, November 24, 2010, 5 PM
If one were to enumerate the most influential and
universal social behaviors in human societies, gossip would undoubtedly
be one of them. Exchanging social information is fundamental for partner
selection, social control, coalition formation, but it also plays a
role in social comparison and group cohesion, just to name some of its
main functions. The most frequent topics of human conversations are
other people’s reputation, actions, choices, and attitudes.
In
this talk I will claim that, far from being mere idle-talk, gossiping is
a socially complex activity people intentionally engage in because of
what they believe about others and how they want others to behave. I
will then present a cognitive theory of gossip and reputation in order
to point out that choosing an addressee, selecting the topic and
deciding whether and how to give a specific information are actions
pursued according to individuals' beliefs and goals. Finally, I will try
to show the complex interplay between the micro-level of agents'
motivations and the macro-level of collective behaviors by presenting
some results from experimental studies within the framework of
Agent-Based Social Simulation (ABSS). In this computational approach,
social phenomena may emerge as a result of interactions among
heterogeneous artificial agents endowed with internal representations of
themselves, their peers and their environment.
The causes of social essentialism
Gil Diesendruck, Bar-Ilan University
Date: ***MONDAY***, November 29, 2010, 5 PM
Adults and children around the world seem to treat categories of people as if they have distinct inherent essences, which make the categories incompatible and permanent. In this talk, I will examine some of the factors that may contribute to the development of such essentialist beliefs about social categories. In particular, I will present data from a recent developmental cross-cultural study on children's social categorization. I will then discuss some ideas about the nature and origins of these beliefs, and describe cultural practices that may help sustain them. I will end with speculations about the possible adaptive function of such beliefs.
Cultural and individual differences in visual cognition
Davie Yoon, Stanford University
Date: Wednesday, December 1, 2010, 5 PM
Where
do our practices of interpreting and attending to the visual world
come from? In this talk, I will discuss two lines of research that
address this broad question in different ways. In the first project, I
will describe young children's (3 to 5-year-olds) striking deficit in
recognizing two-tone / Mooney-type images. These images are trivial for
adults to recognize with a sufficient cue, such as the original
photograph from which the two-tone was derived. We also find that adults
from a remote Amazonian tribe (Piraha) show a similar deficit, and
that when the need to comprehend the referential relationship between
the two-tone and photos is removed, children's recognition improves.
This suggests the phenomenon is related to visual symbolic expertise
(c.f., DeLoache), rather than the consequence of an immature visual
system. In a separate line of research, I will discuss individual
differences in viewing an important social stimulus: the human face. We
measured participants' self-reported degree of autism-associated
traits, and also collected eye-tracking data as they watched a video of
a person speaking under two conditions: (1) gaze directed at the
participant, (2) gaze averted. We found that individual differences in
the level of self-reported autistic-like traits predicted different
levels of direct gaze reciprocation (greater gaze to eye region in the
direct vs the averted condition), perhaps an indication of the
importance of nonconscious gaze mimcry in successful social
interactions.
Perceptual foundations of music in
newborns
Gábor Háden, BME/MTA
Date: Wednesday, December 8, 2010, 5 PM
The universal prevalence
of music in human cultures strongly suggests that music is deeply
rooted in the perceptual and cognitive processes of the human
species. In contrast to some assumptions related to speech
perception, the processes underlying music perception are probably no
specific to music. Music perception can be seen as the product of
interactions between innate predispositions, environmental
constraints, and learning. Finding out which of the abilities
underlying the perception of music are functional at the time of
birth can help to disentangle these interactions.
In this talk, I will
present four studies investigating neonatal abilities underlying the
perception of musical pitch, timbre and rhythm. By applying ERP
measurements, sources of information otherwise hidden by the limited
repertoire of behavioral responses available to newborns can be
tapped. I conclude that babies are born well equipped for gathering
information necessary for music perception, with adult-like abilities
.
