Book excerpt: 'The Essential Tension' explores how agents that naturally compete come to act together as a group. The author argues that the controversial concept of multilevel selection is essential to biological evolution, a proposition set to stimulate new debate. The idea of one collective unit emerging from the cooperative interactions of its constituent (and mutually competitive) parts has its roots in the ancient world. More recently, it has illuminated studies of animal behavior, and played a controversial role in evolutionary biology. In Part I, the author explores the historical development of the idea of a collectivity in biological systems, from early speculations on the sociology of human crowd behavior, through the mid-twentieth century debates over the role of group selection in evolution, to the notion of the selfish gene. Part II investigates the balance between competition and cooperation in a range of contemporary biological problems, from flocking and swarming to experimental evolution and the evolution of multicellularity. Part III addresses experimental studies of cooperation and competition, as well as controversial ideas such as the evolution of evolvability and Stephen Jay Gould’s suggestion that “spandrels” at one level of selection serve as possible sources of variability for the next higher level. Finally, building on the foundation established in the preceding chapters, the author arrives at a provocative new proposition: as a result of the essential tension between competition and cooperation, multiple levels may be essential in order for evolutionary processes to occur at all.

Available in PDF, EPUB and Kindle. Book excerpt: The Intentionality Model builds on the child's engagement in a world of persons and objects, the effort that learning language requires, and the essential tension between engagement and effort that propels language acquisition. According to this perspective, children learn language in acts of expression and interpretation; they work at acquiring language; all aspects of a child's development contribute to this process. Provides results of a longitudinal study which examined language acquisition in the second year of life in the context of developments in cognition, affect, and social connectedness Results of lag sequential analyses are reported to show how different behaviors--words, sentences, emotional expressions, conversational interactions, and construction thematic relations between objects in play--converged, both in the stream of children's actions in everyday events, in real time, an in developmental time between the emergence of words at about 13 months and the transition to simple sentences at about 2 years of age The conclusions show that performance counts for explaining language acquisition; language is not acquired independently but in relation to other behaviors; acquiring language is not easy and requires the work of behavioral coordination
