English resultative expressions have been a major focus of research on the syntax-semantics interface. We argue in this article that a family of related constructions is required to account for their distribution. We demonstrate that a number of generalizations follow from the semantics of the constructions we posit: the syntactic argument structure of the sentence is predicted by general princ...

The evaluation of a patient’s drawing abilities is widely used for the diagnosis of neuropsychological conditions such as visuo-spatial neglect. Conventionally an analysis of simple constructional tasks such as pencil and paperbased drawing tests are analysed by a qualified medical specialist. However, variability in the assessment of these drawing tasks caused by the subjective nature of marki...

1 We propose and implement an alternative source of contextual features for word similarity detection based on the notion of lexicogrammatical construction. On the assumption that selectional restrictions provide indicators of the semantic similarity of words attested in selected positions, we extend the notion of selection beyond that of single selecting heads to multiword constructions exerti...

BACKGROUND/AIMS Constructional apraxia (CA) is usually diagnosed by having patients draw figures; however, the reported assessments only evaluate the drawn figure. We designed a new assessment battery for CA (the Mie Constructional Apraxia Scale, MCAS) which includes both the shape and drawing process, and investigated its utility against other assessment methods. METHODS We designed the MCAS...
