چکیده

In an ERP study we investigate the time course of the interaction between the lexically specified telic role of a noun and the contextually provided ad-hoc affordance induced by a linguistic discourse. If preceded by a neutral discourse context, a verb inconsistent with the telic role in a sentence elicits an enhanced N400 compared to a congruent verb. However, if the preceding discourse context induces an ad-hoc affordance for the object that conflicts with the lexically specified telic role of the referring noun, we observe a crossing-over: compared to the neutral context, the N400 elicited by the inconsistent verb is significantly reduced in this context, whereas the N400 elicited by the congruent verb is significantly enhanced. We interpret these results as a consequence of the immediate functional replacement of the telic role with the contextually triggered ad-hoc affordance, thus supporting a single-step model of sentence meaning composition.

The Time-Course of Sentence Meaning Composition. N400 Effects of the Interaction between Context-Induced and Lexically Stored Affordances

Contemporary semantic theories can be classified along two dimensions: (i) the way and time-course in which contextual factors influence sentence truth-conditions; and (ii) whether and to what extent comprehension involves sensory, motor and emotional processes. In order to explore this theoretical space, our ERP study investigates the time-course of the interaction between the lexically specif...

Agent-Based Context-Aware Ad hoc Communication

This paper presents a technique for combining context information and agent technology to support spontaneous applications in an ad hoc network environment. The multiagent system uses the Ad hoc Context Aware Network (ACAN) infrastructure for context gathering, network setup and application management. Agents manage the process of creating, adapting, policing and terminating applications that r...

Exceptions and anomalies: an ERP study on context sensitivity in autism.

Several studies have demonstrated that people with ASD and intact language skills still have problems processing linguistic information in context. Given this evidence for reduced sensitivity to linguistic context, the question arises how contextual information is actually processed by people with ASD. In this study, we used event-related brain potentials (ERPs) to examine context sensitivity i...
