We investigate whether preschoolers' word learning is selectively attuned to learning word-referent links that they expect will be relevant to their everyday communicative contexts. In two studies, 4-year-olds were taught the name of an unfamiliar toy that they were told was purchased either nearby or faraway. Children's memory for the link was assessed either by a speaker who was not present w...

This article discusses the training of communicative skills by fostering the reflection of speech-receptive action and the opportunities for using software for this purpose. Most frameworks for the training of communicative behavior focus on fostering the observable speech-productive action (i.e. speaking); the individual cognitive processes underlying speech-receptive action (hearing and under...

An alternative theoretical framework for analyzing and designing computer-supported collaborative learning environments is introduced. Bateson’s theory (1973) is used as a starting point for considering in what sense the specific dialogical conditions and qualities of virtual environments may support learning. We need more stringent analytical approaches of research that relate communicative qu...

Young children learn the meanings of thousands of words by the time they can run down the street. Many efforts to explain this rapid development begin by assuming that the computational-level problem being solved is acquisition. Consequently, work in this line has sought to understand how children infer the meanings of words from cues in the communicative signals of the speakers around them. I ...

One of the main problems to be solved while assisting inter-human conflict resolution is how to reuse the previous experience with similar agents. A machine learning technique for handling scenarios of interaction between conflicting human agents is proposed. Scenarios are represented by directed graphs with labelled vertices (for communicative actions) and arcs (for temporal and causal relatio...

How do children learn their first words? Do they do it by gradually accumulating information about the co-occurrence of words and their referents over time, or are words learned via quick social inferences linking what speakers are looking at, pointing to, and talking about? Both of these conceptions of early word learning are supported by empirical data. This thesis presents a computational an...

This study investigated gaze-following abilities as a prerequisite for word learning, in a population expected to manifest a wide range of social and communicative skills-children with a family history of autism. Fifty-three 3-year-olds with or without a family history of autism took part in a televised word-learning task. Using an eye-tracker to monitor children's gaze behavior, it was shown t...
