Working memory limits are best defined in terms of the complexity of the relations that can be
processed in parallel. Complexity is defined as the number of related dimensions or sources …

Accumulating evidence on the nature, function and acquisition of relational knowledge
indicates a crucial role of such knowledge in higher cognitive processes. In this review, we …

Two experiments tested predictions from a theory in which processing load depends on
relational complexity (RC), the number of variables related in a single decision. Tasks from …

People readily generalize knowledge to novel domains and stimuli. We present a theory,
instantiated in a computational model, based on the idea that cross-domain generalization …

A proposal for a categorization of cognition based on core properties of the constituent
processes that integrates theory and empirical findings across domains. All sciences need …

Transitive inference, class inclusion and a variety of other inferential abilities have strikingly
similar developmental profiles—all are acquired around the age of five. Yet, little is known …

Information-processing models help us to understand the data of cognitive development, to
gain new insights, and to frame new and useful questions. They also bring new concepts …

Although the importance of analogy in human cognition has long been recognized (eg,
Piaget 1950; Spearman 1923), and understanding of human analogical reasoning …

Conceptions of human reasoning have shifted from norms based on standard logic to
emergence of reasoning from more fundamental processes. Reasoning entails operating on …

Participants learned about a structure without explicit explanation, either by using relational
schema induction (GS Halford, JD Bain, MT Maybery, & G. Andrews, 1998), which requires …
