This study examined preschool children's reasoning about and behavioral interactions with one of the most advanced robotic pets currently on the retail market, Sony's robotic dog AIBO. Eighty children, equally divided between two age groups, 34-50 months and 58-74 months, participated in individual sessions that included play with and an interview about two artifacts: AIBO and a stuffed dog. Results showed similarities in children's reasoning about the two artifacts, but differences in their behavioral interactions. Discussion focuses on how robotic pets, as representative of an emerging technological genre in HCI, may be (a) blurring foundational ontological categories, and (b) impacting children's social and moral development. More broadly, results inform on our understanding of the human-robotic relationship.

This study examined preschool children's reasoning about and behavioral interactions with one of the most advanced robotic pets currently on the retail market, Sony's robotic dog AIBO. Eighty children, equally divided between two age groups, 34-50 months and 58-74 months, participated in individual sessions with two artifacts: AIBO and a stuffed dog. Evaluation and justification results showed similarities in children's reasoning across artifacts. In contrast, children engaged more often in apprehensive behavior and attempts at reciprocity with AIBO, and more often mistreated the stuffed dog and endowed it with animation. Discussion focuses on how robotic pets, as representative of an emerging technological genre, may be (a) blurring foundational ontological categories, and (b) impacting children's social and moral development.

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.

This study compared teaching and learning measures of 16 mother-child and sibling dyads playing a picture categorization game. Target children (mean age = 3 years 11 months) participated in 2 separate sessions, 1 with their mother and 1 with their older sibling (mean age = 6 years 11 months). Although siblings' teaching styles directed target children to make the correct choices, mothers provided information to help target children make choices on their own. Mothers labeled objects and categories more than siblings. Although target children scored higher with siblings than with mothers, this was because siblings categorized about half of the pictures themselves. Target children labeled objects and categories more with mothers than with siblings. These findings suggest important differences in how mothers and siblings interpreted the goals of the task, offering target children different teaching styles from which to learn.

This study explored the ways in which both parents and older siblings are important resources for young children 's learning in the home context. Parents from 50 Mexicandescent families were interviewed in their homes and were asked questions regarding the kinds of causal questions their children ask, and the different skills their children learn from one another. Parents reported that their children ask questions about complex phenomena in important domains such as biology, physics, and behavior; and parents generally feel good about, and encourage, these questions. Parents also indicated that their children learn different skills from one another; younger siblings learn mostly academic skills from older siblings, and older siblings learn mostly social skills from younger siblings. Both children are reported to learn mostly through observation and imitation of one another Findings are discussed in relation to the issues of "match" between homes and schools as complementary contexts for young children's learning.
