Poverty of the stimulus has been at the heart of ferocious and tear-filled debates at the nexus of psychology, linguistics, and philosophy for decades. This review is intended as a guide for readers without a formal linguistics or philosophy background, focusing on what poverty of the stimulus is and how it's been interpreted, which is…

The induction problems facing language learners have played a central role in debates about the types of learning biases that exist in the human brain. Many linguists have argued that some of the learning biases necessary to solve these language induction problems must be both innate and language-specific (i.e., the Universal Grammar (UG)…

The papers in this special issue of "Language and Cognitive Processing" on the neural bases of language production illustrate two general approaches in current cognitive neuroscience. One approach focuses on investigating cognitive issues, making use of the logic of associations/dissociations or the logic of neural markers as key investigative…

Conditionals in natural language are central to reasoning and decision making. A theoretical proposal called the Ramsey test implies the conditional probability hypothesis: that the subjective probability of a natural language conditional, P(if p then q), is the conditional subjective probability, P(q [such that] p). We report three experiments on…

Three studies investigated the effects of concrete versus abstract wording and negative versus positive premises on the difficulty subjects had in solving several kinds of reasoning tasks. Subjects for all three studies were college undergraduates who received booklets containing either hypothetical, disjunctive, or linear syllogisms. Each booklet…

Investigates in an experimental setting the claim that young children have some knowledge of the rules of correspondence between language and reality which are central to propositional logic. (EKN)

The present paper describes results of a study that investigated 209 bilingual Puerto Rican college students' ability to solve verbal deductive reasoning problems administered in Spanish and English in relation to their reading comprehension skills in either language. A series of confirmatory factor analyses revealed that the data on reasoning and…

Examines recall of passages in order to determine relative importance of lines according to their function in argument. Results indicate that hypothetical assumptions and their logical consequences are less well remembered than facts and that facts introduced are better recalled than facts conducted in the course of an argument. (EKN)

The ways in which preschoolers use the word "but" were studied. It was found that the eight preschoolers, who ranged in age from 3;9 to 5;5, were able to use "but" to express a number of different types of adversative relationships. "But" introduced clauses containing information that: (1) contrasted with shared knowledge about the usual state of…

This study examined the effects of certain contextual linguistic variables on the logical performance of subjects in grades 4, 6, and 12 of selected British Columbia schools as well as some theoretical problems underlying assessment of the development of logical abilities. The task consisted of 27 syllogistic problems based upon the information…

Examines comprehension of sentences with multiple negations among 71 monolingual Anglo and bilingual Hispanic undergraduate science and engineering majors. Finds that both groups misused rules of logic and natural discourse; similar groups benefited from training to eliminate inappropriate reasoning strategies, but only Anglos retained the…

A discussion of the translation process focuses on inferencing strategy, using attributes and contexts that are familiar in recognizing or making sense of what is unfamiliar in a text. Examples drawn from Belgian translation student work are used to illustrate this principle in operation, at several levels of difficulty. The examples come from…

Three experimental studies were carried out to examine the ability of groups of learners of English as a second language to solve problems of deductive reasoning (three term linear syllogisms) in their native and second languages. In the first study involving Canadian francophones studying English, subjects solved problems more effectively in…

This study investigates the role of inferencing in cloze test performance and the factors that facilitate that inferencing. Four groups of high school students learning French as a second language completed sets of cloze passages under four treatment conditions. Three conditions provided a potential cue to inferencing, while the fourth was a…
