This chapter considers the two main approaches to deductive thinking: theories based on formal rules of inference postulate that deduction is a syntactic process akin to a logical proof; the mental model theory postulates that it is a semantic process akin to the search for counterexamples. Experimental evidence bears out the predictions of the model theory: the more models needed for a deduction, the harder it is; erroneous conclusions are consistent with the premises; and ^general knowledge… Expand

Models , rules , and deductive reasoning 1
We formulate a simple theory of deductive reasoning based on mental models. One prediction of the theory is experimentally tested and found to be incorrect. The bearing of our results on contemporaryExpand
Dissociation of Mechanisms Underlying Syllogistic Reasoning
TLDR
It is concluded that syllogistic reasoning is implemented in two distinct systems whose engagement is primarily a function of the presence or absence of semantic content. Expand
Recomposing a fragmented literature: How conditional and relational arguments engage different neural systems for deductive reasoning
TLDR
It is shown that the nature of the logical argument, whether it is relational or conditional, determines which neural system is engaged, which suggests that conditional reasoning relies more on so-called syntactic processes than relational reasoning, while relational reasoning may rely on visuo-spatial processes and mental imagery more than conditional reasoning.

The dynamics of deductive reasoning: An fMRI investigation
TLDR
A long-range supramodal network active during reasoning processes including areas in the left frontal and parietal regions as well as the bilateral caudate nucleus is identified using event-related fMRI and an auditory and visual conjunction technique. Expand
Anatomy of deductive reasoning
  • V. Goel
  • Psychology, Medicine
  • Trends in Cognitive Sciences
  • 2007
TLDR
The literature on the neural basis of deductive reasoning from the past decade is reviewed and several interesting patterns are identified and articulate their implications for cognitive theories of reasoning. Expand
Neuroanatomical Correlates of Human Reasoning
TLDR
The results are consistent with previous neuroimaging studies and raise questions about the level of involvement of classic spatial regions in reasoning about linguistically presented spatial relations. Expand
Cognitive Neuroscience of Deductive Reasoning
It is 4pm and I hear the school bus pull up to the house. Soon there is the taunting of a 13-year-old boy followed by the exaggerated screams of an 8-year-old girl. My kids are home from school.Expand
Journal of Cognitive Neuroscience 10:3
■ One of the important questions cognitive theories of reasoning must address is whether logical reasoning is inherently sentential or spatial. A sentential model would exploit nonspatialExpand
The Perceptual Nature of Mental Models
Abstract In the first comprehensive formulation of the theory of mental models, Johnson-Laird proposes several constraints on any psychological theory of reasoning. He argues that his theory fulfillsExpand
Evidence for Dual Neural Pathways for Syllogistic Reasoning
We review data from three neuroimaging studies of syllogistic reasoning that point to dual neural pathways for human reasoning. A frontal-temporal system processes familiar, conceptually coherentExpand

Reasoning by model: The case of multiple quantification.
TLDR
A theory of deductive reasoning is presented for a major class of inferences that depend on multiply-quantified premises and it is argued that reasoneis construct mental models based on their knowledge of the meanings of quantifiers (and other terms, including relational expressions). Expand
Mental Models : Towards a Cognitive Science of Language
Mental Models offers nothing less than a unified theory of the major properties of mind: comprehension, inference, and consciousness. In spirited and graceful prose, Johnson-Laird argues that weExpand
Some Empirical Justification for a Theory of Natural Propositional Logic
TLDR
Evidence supporting a particularRepertory as the repertory of the kinds of inferences basic to the propositional reasoning of adults untutored in logic is presented. Expand
Mental models and temporal reasoning
TLDR
Five experiments investigating reasoning based on temporal relations, such as: "John takes a shower before he drinks coffee", corroborate the mental model theory and develop a computer program that reasons in this way. Expand
Believability and syllogistic reasoning
TLDR
The data show that beliefs both affect the examination of alternative models and act as a filter on putative conclusions, and it is shown how some types of problem and some problem contents make the existence ofAlternative models more obvious than others. Expand
How Diagrams Can Improve Reasoning
We report an experimental study on the effects of diagrams on deductive reasoning with double disjunctions, for example: Raphael is in Tacoma or Julia is in Atlanta, or both. Julia is in Atlanta orExpand
Inference deficits in right brain-damaged patients
TLDR
Results showed that RHD patients have more trouble answering inference questions, especially those concerning incorrect inferences, than answering questions about the factual content of the passages, which suggest the impairment of several components of normal discourse processing subsequent to right hemisphere brain damage.

The title of this book excited me. I thought, at last I would find out the truth about lateralization and localization of discourse abilities. I thought the chapters would c o n f m my suspicion thatExpand

TLDR
It was concluded that either the left-temporal-lobe group had an unexpectedly large verbal comprehension deficit, or the form of imagery utilized in solving deductive-reasoning problems is based upon verbal symbolic information, and as such is mediated by the left hemisphere. Expand
