The distinction between abstract and concrete concepts is fundamental to cognitive linguistics and cognitive science. This distinction is commonly operationalized through concreteness ratings based on the aggregated judgments of many people. What is often overlooked in experimental studies using this operationalization is that ratings are attributed to words, not to concepts directly. In this paper we explore the relationship between the linguistic properties of English words and conceptual abstractness/concreteness. Based on hypotheses stated in the existing linguistic literature we select a (...) set of variables and verify whether they are statistically associated with concreteness ratings. We show that English nouns are rated as more concrete compared to other parts of speech, but mass nouns are rated as less concrete than count nouns. Furthermore, a more complex morphological structure is associated with abstractness, and as for etymology, French- and Latin-derived words are more abstract than words of other origin. This shows that linguistic properties of words are indeed associated with the degree of concreteness that we attribute to the underlying concepts, and we discuss the implications that these findings have for linguistic theory and for empirical investigations in the cognitive sciences.

This article proposes an analysis of the gestural production of people suffering from fluent or non-fluent aphasia in comparison with the gestures performed by speakers not suffering from any language disorder. The interest of such a study is twofold: firstly, it allows a better understanding of what happens to gestures during the numerous speech dysfluencies caused by the speech impairment. Among other things, it sheds light on the links between speech and gestures in multimodal face-to-face interaction. Despite the profusion of (...) work on aphasia, very little is still known about the characteristics of the gestures performed spontaneously by aphasic people. The study presented here is based on video examples from the AphasiaBank corpus to illustrate the specific features of the speech and gestures of atypical speakers and gives a more detailed description of the gestural production of people with aphasia. This knowledge can inform post-stroke rehabilitation procedures that rely on some form of multimodal speech therapy in order to adapt to the various communication needs of the patients. (shrink)
