行为的社会传播可以通过不同的机制来实现。灵长类动物社会学习的研究通常区分两种形式的信息，学习者可以从演示者：复制动作（定义为模仿）或复制的结果（定义为模仿）。我们提出了这些学习机制（加上纯粹的个人学习）的分解，其中包含的核心思想，社会学习可以表示为一个最佳的行为，是由不同种类的信息约束的搜索。我们用一个基于个人的模型来说明我们的方法，在这个模型中，个人在抽象的“空间”中解决任务，这些空间代表行为动作、结果和这些结果的好处。根据他们掌握的学习机制，个人对这些空间所传达的信息有不同的获取机会。我们展示了不同类别的任务如何为具有不同学习机制的个人提供独特的优势，并讨论了我们的方法如何有助于当前社会学习和文化的实证和理论研究。
Social transmission of behavior can be realized through distinct mechanisms. Research on primate social learning typically distinguishes two forms of information that a learner can extract from a demonstrator: copying actions (defined as imitation) or copying only the consequential results (defined as emulation). We propose a decomposition of these learning mechanisms (plus pure individual learning) that incorporates the core idea that social learning can be represented as a search for an optimal behavior that is constrained by different kinds of information. We illustrate our approach with an individual-based model in which individuals solve tasks in abstract "spaces" that represent behavioral actions, results, and benefits of those results. Depending on the learning mechanisms at their disposal, individuals have differential access to the information conveyed in these spaces. We show how different classes of tasks may provide distinct advantages to individuals with different learning mechanisms and discuss how our approach contributes to current empirical and theoretical research on social learning and culture.
