Linguistic determinism and theory of mind in deaf children

DeVilliers and DeVilliers (2000, 2005) propose that deaf and hearing children acquire a theory of mind (or the understanding that human behaviour is the product of psychological states like true and false beliefs) as a consequence of their linguistic mastery of a rule of syntax. Specifically, they argue that the syntactic rule for sentential complementation with verbs of speech (e.g., “say”) precedes syntactic mastery of complementation for cognition (e.g., “think”) and both of these developmentally precede and promote conceptual mastery of a theory of mind (ToM), as indexed via success on standard false belief tests. The present study examined this proposition in groups of primary-school-aged deaf children and hearing preschoolers who took false belief tests and a modified memory for complements test that included control questions. Guttman scaling techniques indicated no support either for the prediction that syntactic skill precedes ToM understanding or for the earlier emergence of complementation for “say” than for “think”. Methodological issues and implications for deaf children's ToM development are discussed.

A linguistic resurrection? Aller + infinitive in narrative past contexts

This article studies the go periphrasis emerging in Contemporary French narrations and compares it with the narrative go periphrasis found in Middle French.

Author identification, idiolect and linguistic uniqueness

For forty years linguists have talked about idiolect and the uniqueness of individual utterances. This article explores how far these two concepts can be used to answer certain questions about the authorship of written documents—for instance how similar can two student essays be before one begins to suspect plagiarism? The article examines two ways of measuring similarity: the proportion of shared vocabulary and the number and length of shared phrases, and illustrates with examples drawn from both actual criminal court cases and incidents of student plagiarism. The article ends by engaging with Solan and Tiersma's contribution to this volume and considering whether such forensic linguistic evidence would be acceptable in American courts as well as how it might successfully be presented to a lay audience.

Applications of the behavioural homogeneity evaluation framework: the predictive ability of consumer involvement for international food market segmentation

This article proposes a framework of alternative international marketing strategies, based on the evaluation of intra- and inter-cultural behavioural homogeneity for market segmentation. The framework developed in this study provides a generic structure to behavioural homogeneity, proposing consumer involvement as a construct with unique predictive ability for international marketing strategy decisions. A model-based segmentation process, using structural equation models, is implemented to illustrate the application of the framework.
