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 six domains (transitivity, hierarchical classification, class inclusion, cardinality, relative-clause sentence comprehension, and hypothesis testing) were administered to children aged 3-8 years. Complexity analyses indicated that the domains entailed ternary relations (three variables). Simpler binary-relation (two… Expand
Measuring the Influence of Complexity on Relational Reasoning
Relational complexity (RC) theory conceptualizes an individual’s processing capacity and a task’s complexity along a common ordinal metric. The authors describe the development of the Latin SquareExpand
Integration of Category Induction and Hierarchical Classification: One Paradigm at Two Levels of Complexity
Hierarchical classification (HC) and category induction (CI) were tested by a common property inference procedure to facilitate comparison and enable relative complexities to be assessed. RelationalExpand
Relational processing and working memory capacity in comprehension of relative clause sentences
TLDR
Comprehension of object-relatives relied more heavily on a domain-general capacity to process complex relations than on WM capacity, and working memory capacity was assessed using reading span or forward and backward digit span tests. Expand
Theory of mind and relational complexity.
TLDR
Connections and transformations were easier and mastered earlier than TOM; predictor tasks accounted for more than 80% of age-related variance in TOM; and ternary-relational items accounted for TOM variance, before and after controlling for age and binary- Relational items. Expand
Two Sources of Age-Related Decline in Comprehension of Complex Relative Clause Sentences
Working memory capacity is thought to underlie many higher cognitive processes including sentence comprehension. Sentences that contain object-extracted relative clauses are more complex and imposeExpand
Relational thinking in later adulthood.
TLDR
Age had a significant impact in the structural model with fluid intelligence (matrix reasoning) as the outcome variable, suggesting that the processes underpinning age-related declines in matrix reasoning are more diverse than those assessed in the current research. Expand

Abstract Four experiments investigated 4- to 6-year-olds' transitive inferences. In Experiments 1–3, there was a nonmapping condition in which inferences were made either about stacked blocks, orExpand
Processing capacity defined by relational complexity: implications for comparative, developmental, and cognitive psychology.
TLDR
Embedded models of relational representations show that relations with more arguments have a higher computational cost that coincides with experimental findings on higher processing loads in humans, and the complexity of relations processed by children increases with age. Expand

TLDR
It is shown that information-processing and psychometric measures are in much closer correspondence when account is taken of one's problem-solving strategy, and the relation between g and the idea of attentional resources is explored, by applying the dual task methodology to memory and reasoning tests.
