This paper investigates six- to nine-year-old children's acquisition of evidentiality. In two minimally different tasks we assess whether children can be made to use a particular source of information by presenting them with a specific evidential term. That is, we assess whether children have an explicit awareness of the source requirement of the…

Extensive exposure to representational media is common for infants in Western culture, and previous research has shown that soon after their 1st birthday, infants can acquire and extend new information from pictures to real objects. Here we explore the extent to which lack of exposure to pictures during infancy affects children's learning from…

Imitation of people on educational television is a potential way for very young children to learn new skills. Although toddlers in previous studies exhibited a "video deficit" in learning, 24-month-olds in Study 1 successfully reproduced behaviors modeled by a person who was on video as well as they did those modeled by a person who was present in…

Examined the effect of experience on children's use of video-presented information. Found that after seeing themselves "live" on their family television for 2 weeks, 2-year-olds reliably used a live video presentation of an adult hiding a toy to find the toy in an object-retrieval task. Most also transferred what they learned to a task…

A study of 52 teachers of grades 1 thorugh 4 from 18 schools in an urban setting indicated that teachers functioning at higher conceptual levels did not seek more information and resources than teachers functioning at lower levels, but appeared better able to identify optimal sources of assistance and the most direct routes to resources. The study…

Examined preschoolers' suggestibility when initial beliefs about an object's identity were contradicted by experimenter's suggestion. Found that subjects were good at accepting the suggestion only when the experimenter was better informed than they. Children were least accurate at reporting whether their final belief was based on what they were…

This study considered differences in induction of biological properties between children and preadolescents based on differences in stimuli processing in these two groups. Two experiments tested predictions that young children, but not preadolescents, base their inductive inference on aggregating information from different sources rather than…

Compared parental perceptions of the use of internal information sources--intuitions, religious beliefs, personal childhood experiences--to use of external sources for information about their toddlers' development. Found that parents perceived the internal sources as being used more frequently and as more useful for information on their child's…

Examined whether toddlers would use information presented through video to solve a retrieval problem. Found that 2.5-year-olds were very successful at finding a hidden toy based on viewing a televised hiding event, but 2-year-olds were not. Substantially better performance was achieved by other 2-year-olds who either watched or believed they were…
