The social-pragmatic theory of language acquisition proposes that children only become efficient at learning the meanings of words once they acquire the ability to understand the intentions of other agents, in particular the intention to communicate (Akhtar & Tomasello, 2000). In this paper we present a neural network model of word learning which…

Body movement provides a rich source of cues about other people's goals and intentions. In the present research, we investigate how well people can distinguish between different social intentions on the basis of movement information. Participants observed a model reaching toward and grasping a wooden block with the intent to cooperate with a…

Infants intentionally communicate with others from before their 1st birthday. But there is some question about how they understand the communicative process. Do they understand that for their request to work the recipient must both understand the request and be cooperatively disposed to fulfill it? On the basis of the study by Shwe and Markman…

Ten- and 14-month-old infants' gaze was recorded as the infants observed videos of different hand actions directed toward multiple goals. Infants observed an actor who (a) reached for objects and displaced them, (b) reached for objects and placed them inside containers, or (c) moved his fisted hand. Fourteen-month-olds, but not 10-month-olds,…

The ability to understand that goals and other intentional relations are attributes of individual people is of fundamental importance to social life. It enables us to predict and interpret actions on-line by relating a person's prior and current behaviors, and distinguishing them from the behaviors of other persons. In this paper, we consider the…

The study investigated children's intention understanding using a longitudinal design. Thirty-two Italian children were tested on the "Demonstration of Intention" in the Re-enactment paradigm devised by Meltzoff (1995a), at two ages. Mean age was 12 months at the first session and 15 months at the second session. Previous research by…

The ideas of Vygotsky [Vygotsky, L. S. (1987). "Thinking and speech." In "The collected works of L. S. Vygotsky," (Vol. 1). New York: Plenum. (Original work published 1934.)] have been increasingly influential in accounting for social-environmental influences on the development of social understanding (SU). In the first part of this article, I…

The aim of this study was to evaluate the behavioral determinants of the initiation of breast-feeding at birth. The prospective cohort study used the attitude, social influence, self-efficacy (ASE) model in 373 pregnant women in five child health care centers. Prenatally, 72% of the women had the intention to breast-feed, and 73% actually started…

Examined 2-year-olds' language acquisition with an emphasis on the agency and intentionality of the child. Concluded that development depends on the child's expression of intentionality by actions (performance), the essential tension between the child's engagement and effort, and the integration of linguistic, cognitive, and social aspects of the…
