The order of things: Inferring causal structure from temporal patterns
نویسندگان
چکیده
The timing and order in which a set of events occur strongly influences whether people judge them to be causally related. But what do people think particular temporal patterns of events tell them about causal structure? And how do they integrate multiple pieces of temporal evidence? We present a behavioral experiment that explores human causal structure induction from multiple temporal patterns of observations. We compare two simple Bayesian models that make no assumptions about delay lengths, assume that causes must precede their effects but differ in whether they assume simultaneous events can also be causally connected. We find that participants’ judgments are in line with the model that rules out simultaneous causation. Variants of this model that assume people update their beliefs conservatively provide a close fit to participants’ judgments. We discuss possible psychological bases for this conservative belief updating and how we plan to further explore how people learn about causal structure from time.

Strategy Changes as a Function of Task Complexity in Causal Structure Learning
The authors previously demonstrated that people emphasized covariation rather than temporal order as a clue to inferring causal structure, whereas Lagnado and Sloman (2006) showed the opposite results that temporal order overrode covariation. The authors proposed the interpretation that these conflicting findings resulted from task complexity, since covariation becomes more complicated as the n...
متن کاملRunning head: INFERRING CAUSAL VARIABLES FROM CONTINUOUS ACTION SEQUENCES 1 Inferring action structure and causal relationships in continuous sequences of human action
In the real world, causal variables do not come pre-identified or occur in isolation, but instead are embedded within a continuous temporal stream of events. A challenge faced by both human learners and machine learning algorithms is identifying subsequences that correspond to the appropriate variables for causal inference. A specific instance of this problem is action segmentation: dividing a ...
متن کاملMethodology for Inferring Moral Priorities According to the Narrations of "Afal Tafzil"
Considering the different levels of moral values in Islam, in order to know the most important values and also to eliminate the contradiction, it is necessary to deduce from the texts of verses and hadiths. One of the most important aspects in these texts is the "structure of Tafzil". Some narrations of this structure indicate the priority of one or more values and others indicate a rule in det...

In constructing probabilistic networks from human judgments, we use causal relationships to convey useful patterns of dependencies. The converse task, that of inferring causal relationships from patterns of dependencies, is far less understood. Th’ 1s paper establishes conditions under which the directionality of some interactions can be determined from non-temporal probabilistic information an...
