 While social learning is a central concern to those focused on culture, other forms of learning are also important for understanding the range of interactions between cognition, culture and its accumulation, and perhaps the evolution of cultural capacities themselves. For instance, while social learning appears to be suited to contribute to the rapid spread of new behaviors and beliefs in a population, individual learning may be better suited to contribute to the initial generation of new behaviors, novel beliefs, and to the production of innovations on existing cultural variants. Theorists have carved out different positions on how the distinction between individual and social learning should be conceived, and how these two facets of cultural capacities might interact.
