Causal Learning: Psychology, Philosophy, and ComputationUnderstanding causal structure is a central task of human cognition. Causal learning underpins the development of our concepts and categories, our intuitive theories, and our capacities for planning, imagination and inference. During the last few years, there has been an interdisciplinary revolution in our understanding of learning and reasoning: Researchers in philosophy, psychology, and computation have discovered new mechanisms for learning the causal structure of the world. This new work provides a rigorous, formal basis for theory theories of concepts and cognitive development, and moreover, the causal learning mechanisms it has uncovered go dramatically beyond the traditional mechanisms of both nativist theories, such as modularity theories, and empiricist ones, such as association or connectionism. |

But, every time I look at one of the papers, all I see are unintelligible sentences like this: For any variable R in the directed graph, the graph represents the proposition that for any set S of variables in the graph (not containing ...

The graphs consist of variables, representing types of events or states of the world and directed edges (arrows) representing the direct causal relations between those variables. The variables can be discrete (like school grade) or ...

The covariation among the variables by itself is consistent with both these structures. You can discriminate between these two graphs by looking at the patterns of conditional probability among the three variables.

The Intervention Assumption A variable I is an intervention on a variable X in a causal graph if and only if (a) I is exogenous (that is, it is not caused by any other variables in the graph), (b) directly fixes the value of X to x, ...

The Faithfulness Assumption In the joint distribution on the variables in the graph, all conditional independencies are consequences of the Markov assumption applied to the graph. Given the faithfulness assumption, it is possible to ...
