A theory of communication between autonomous agents should make testable predictions about which communicative behaviors are collaborative, and provide a framework for determining the features of a communicative situation that affect whether a behavior is collaborative. The results presented here are derived from a two-phase empirical method. First, we analyze a corpus of naturallyoccurring pro...

To what extent do speaker-external communicative pressures versus speaker-internal cognitive pressures affect utterance form? Four experiments measured speakers' references to privately known (i.e., privileged) objects when naming mutually known (i.e., common ground) objects. Although speaker-external communicative pressures demanded that speakers avoid references to privileged objects, 2 exper...

An alternative view to the traditionally held view that schizophrenia is characterised by severely disordered cognition is presented. It is possible that apparently self-contradictory expressions of schizophrenics are well-formed communicative expressions of highly ordered cognitive systems. Building on the premise that behaviour is in general communicative, and using GšdelÕs Incompleteness The...

In both gesture and sign, objects and events can be represented by reproducing some of their features iconically. Iconic gestures do not typically appear until well into children’s second year of life, suggesting that the cognitive and/or communicative resources required are not trivial. Here we investigate how manual iconicity develops in two different communicative systems. Using longitudinal...

In this article, a dialogue game is presented in which coherent conversational sequences with inconsistent and biased information are described at the speech act level. Inconsistent and biased information is represented with bilattice structures, and based on these bilattice structures, a multi-valued logic is defined that makes it possible to describe a dialogue game in which agents can commun...

This paper presents an analysis of dysfluencies in two oral retellings of a familiar children’s story by a young boy with autism. Thurber & Tager-Flusberg (1993) postulate a lower degree of cognitive and communicative investment to explain a lower frequency of non-grammatical pauses observed in elicited narratives of children with autism in comparison to typically developing and intellectually ...

Task difficulty across different macro-genres continues to remain among less attended areas in second language development studies. This study examined the correlation between task difficulty across the descriptive, narrative, argumentative, and expository macro-genres. The three components of task difficulty (i.e., code complexity, cognitive complexity, and communicative stress) were also comp...
