Comments on an article by Rips et al. L. J. Rips, S. Blok, and G. Newman (2006) proposed that singular concepts, which support the tracing of individual objects across their existence, are governed by a principle of causal continuity. They purported to show that causal continuity is better than existing theories at explaining judgments of the…

Responds to comments made by Rhemtulla and Xu on the current authors' original paper Concepts of individual objects (e.g., a favorite chair or pet) include knowledge that allows people to identify these objects, sometimes after long stretches of time. In an earlier article, the authors set out experimental findings and mathematical modeling to…

"Theory as Method: Small Theories of Treatments," by Mark W. Lipsey, is one of the most influential and highly cited articles to appear in "New Directions for Evaluation." It articulated an approach in which methods for studying causation depend, in large part, on what is known about the theory underlying the program. Lipsey discussed the benefits…

This paper comments on the articles by Cheng and by Novick and Cheng. It has been claimed that the power PC theory reconciles regularity and power theories of causal judgment by showing how contingency information is used for inferences about unobservable causal powers. Under the causal powers theory causal relations are understood as generative…

In this article, the author presents his views on Michael's (1975) and Baron and Galizio's (2005) arguments on eliminating the distinction between positive and negative reinforcement. He first discusses Michael's concept of these two types of operations and contrasts it with the notions of Baron and Galizio. The author provides the readers his own…

Baron and Galizio (2005) reviewed and updated Michael's (1975) observations concerning the problems surrounding the distinction between positive and negative reinforcement. In the end they concluded that the valence is unjustified. However, despite the fact that the logical and empirical underpinnings of the distinction have been questioned for…

Responds to John J. Kim's critique of his studies of preschoolers' understanding of race. Maintains that his and others' investigations demonstrate that preschoolers differentiate the pattern of causal reasoning governing transmission and maintenance of racial characteristics from that governing transmission and maintenance of perceptually similar…
