By responding to information gained through observing or interacting with other individuals, fish can learn about important aspects of their environment, including where to forage, how to recognize and avoid predators, and who to mate with. Social learning processes are often closely intertwined with the social environment; whether individuals engage in social learning, who they learn from, and what they learn frequently depend on complex, nonrandom patterns of social interaction. Social network analysis provides a sophisticated toolset for quantifying such elements of social structure. In this chapter, we discuss how integrating social network approaches with investigations into social learning have provided novel and important insights regarding the ways in which fish acquire and use social information in realistic social contexts.

In Chapter Four, “Crowds and Agility,” the project turns to the fully imagined agile movement and potential virtuosity of modernist crowds, their reworked vocabularies across, and between media, their effectiveness in turning situations to advantage, and their conflictual relations with federating powers, established inequities, and inherited elitisms. In order to demonstrate the full scope of potentials involved, the chapter opens up to range more widely across a variety of media, aesthetics, and categories of works within modernism that simultaneously contribute to contriving a social space and interfering with its undemocratic spectacularization. In its most fully realized form, the modernist agile crowd claims to be unclassifiable within previous categories of social fields, and insists on a fundamental heterogeneity at the level of demand and composition.
