Reasoning about artifacts at 24 months: the developing teleo-functional stance.

From the age of 2.5, children use social information to rapidly form enduring function-based artifact categories. The present study asked whether even younger children likewise constrain their use of objects according to teleo-functional beliefs that artifacts are "for" particular purposes, or whether they use objects as means to any desired end. Twenty-four-month-old toddlers learned about two novel tools that were physically equivalent but perceptually distinct; one tool was assigned implicit function information through a short demonstration. At test, toddlers returned to the demonstrated tool when asked to repeat the task, but, unlike older children, also used it for another task. Results imply that at 24 months, toddlers expect artifacts to have functions and proficiently use a model's intentional use to inform tool choices, suggesting cognition that differs from that of tool-using monkeys. However, their artifact representations are not yet specified enough to support exclusive patterns of tool use.

Time to get a new mountain? The role of function in children's conceptions of natural kinds.

Prior research indicates that young children are promiscuously teleological, attributing purpose not only to artifacts, but also to living and non-living natural entities. This study further examines the role of function in children's reasoning about different object kinds by indirectly probing children's intuitions about what types of entities can be rendered functionless. Specifically, children were asked to decide whether entities that could no longer perform certain activities should be fixed/replaced (e.g. "Do you need to get a new one?"). Results reveal that young children broadly view both artificial and natural kinds that can no longer perform certain activities as needing to be fixed or replaced. These findings suggest that the teleo-functional bias not only influences children's explanatory preferences but also their category judgments.

Why things happen: teleological explanation in parent-child conversations.

Research indicates that young children, unlike adults, have a generalized tendency to view not only artifacts but also living and nonliving natural phenomena as existing for a purpose. To further understand this tendency's origin, the authors explored parents' propensity to invoke teleological explanation during explanatory conversations with their children. Over 2 weeks, Mexican-descent mothers were interviewed about question-answer exchanges with their preschool children. Analyses revealed that children asked more about biological and social phenomena than about artifacts or nonliving natural phenomena, with most questions ambiguous as to whether they were requests for causal or teleological explanations. In responding to these ambiguous questions, parents generally invoked causal rather than teleological explanations. The tendency to favor causal explanation was confirmed by analyses of transcripts from a longitudinal study of spontaneous speech in a father-son dyad. These results suggest that children's bias toward teleological explanation does not straightforwardly derive from parent explanation.

Young children's rapid learning about artifacts.

Tool use is central to interdisciplinary debates about the evolution and distinctiveness of human intelligence, yet little is actually known about how human conceptions of artifacts develop. Results across these two studies show that even 2-year-olds approach artifacts in ways distinct from captive tool-using monkeys. Contrary to adult intuition, children do not treat all objects with appropriate properties as equally good means to an end. Instead, they use social information to rapidly form enduring artifact categories. After only one exposure to an artifact's functional use, children will construe the tool as 'for' that particular purpose and, furthermore, avoid using it for another feasible purpose. This teleo-functional tendency to categorize tools by intentional use represents a precursor to the design stance - the adult-like tendency to understand objects in terms of intended function - and provides an early foundation for apparently distinctive human abilities in efficient long-term tool use and design.

Are children "intuitive theists"? Reasoning about purpose and design in nature.

Separate bodies of research suggest that young children have a broad tendency to reason about natural phenomena in terms of purpose and an orientation toward intention-based accounts of the origins of natural entities. This article explores these results further by drawing together recent findings from various areas of cognitive developmental research to address the following question: Rather than being "artificialists" in Piagetian terms, are children "intuitive theists"-disposed to view natural phenomena as resulting from nonhuman design? A review of research on children's concepts of agency, imaginary companions, and understanding of artifacts suggests that by the time children are around 5 years of age, this description of them may have explanatory value and practical relevance.

British and American children's preferences for teleo-functional explanations of the natural world.

Teleological-functional explanations account for objects by reference to their purpose. They are a fundamental aspect of adults' explanatory repertoire. They also play a significant role in children's reasoning although prior findings indicate that, in contrast to adults, young children broadly extend teleological explanation beyond artifacts (e.g. chairs) and biological properties (e.g. eyes) to the properties of non-living natural phenomena (e.g. clouds, rocks). The present study extends earlier work with American children to explore British children's application of teleological explanation. The motivation is that while Britain and America are, culturally, as close to a minimal pair as the global context affords, there are differences in the religiosity of the two nations such that British children might be less inclined to endorse purpose-based explanation. Results reveal that young British children also possess a promiscuous teleology although they differ in the kinds of purposes that they attribute. Additional findings include a replication of earlier effects using a modified task with young American children.
