The connections between emotion and rationality are reexamined. Historically, Plato’s doctrine of the tripartite soul has established the preconception of a strict separation of emotion/passion from cognition/rationality, encouraging the biased perception that emotions are inherently irrational. To examine whether emotions can be rational, one must first examine the various meanings of rational...

Two experiments used a mutual imitation paradigm to assess 9-, 14-, and 18-month-old infants’ developing understanding of intentions in others. In the first study, 1 experimenter imitated the infants’ actions, and another experimenter performed contingent but different actions on an identical toy. From 9 months of age, infants show discrimination between the mimicking and the contingent experim...

For a set Ω an unordered relation on Ω is a family R of subsets of Ω . If R is such a relation we let G(R) be the group of all permutations on Ω that preserve R, that is g belongs to G(R) if and only if x ∈R implies x ∈R. We are interested in permutation groups which can be represented as G= G(R) for a suitable unordered relation R on Ω . When this is the case, we say that G is defined by the r...

The componential theory of creativity is a comprehensive model of the social and psychological components necessary for an individual to produce creative work. The theory is grounded in a definition of creativity as the production of ideas or outcomes that are both novel and appropriate to some goal. In this theory, four components are necessary for any creative response: three components withi...

The flow in a rapidly rotating cylinder forced to precess through a nutation angle α is investigated numerically, keeping all parameters constants except α, and tuned to a triadic resonance at α = 1◦. When increasing α, the flow undergoes a sequence of well-characterized bifurcations associated with triadic resonance, involving heteroclinic and homoclinic cycles, for α up to about 4◦. For large...

Are children as young as 2 years old able to interact in groups of three? The study applied the family triad model first introduced by Parke, Power, and Gottman (1979) to the case of peer interaction. In Experiment 1, the model was refined for use in studies of peer interaction and applied to an existing dataset of 16 triads of newly acquainted 24-month-olds. In Experiment 2, the triadic coding...

Services such as Wikipedia, Flickr, Technorati, Yahoo!, YouTube, del.icio.us appear in many web applications, employ the folksonomy as their social tagging mechanism, where users assign tags to resources and share it with each other within their community. As the number of the folksonomy-based systems is increased, some proper data mining approaches to folksonomies are necessary to better under...

Disentangling the mechanisms underlying the social network evolution is one of social science’s unsolved puzzles. Preferential attachment is a powerful mechanism explaining social network dynamics, yet not able to explain all scaling-laws in social networks. Recent advances in understanding social network dynamics demonstrate that several scaling-laws in social networks follow as natural conseq...

Triadic distance models can be used to analyse proximity data defined on triples of objects. Three-way symmetry is a common assumption for triadic distance models. In the present study three-way symmetry is not assumed. Triadic distance models are presented for the analysis of asymmetric three-way proximity data that result in a simultaneous representation of symmetry and asymmetry in a low-dim...
