New Caledonian crows make and use tools, and tool types vary over geographic landscapes. Social learning may explain the variation in tool design, but it is unknown to what degree social learning accounts for the maintenance of these designs. Indeed, little is known about the mechanisms these crows use to obtain information from others, despite the question’s importance in understanding whether tool behavior is transmitted via social, genetic, or environmental means. For social transmission to account for tool-type variation, copying must utilize a mechanism that is action specific (e.g., pushing left vs. right) as well as context specific (e.g., pushing a particular object vs. any object). To determine whether crows can copy a demonstrator’s actions as well as the contexts in which they occur, we conducted a diffusion experiment using a novel foraging task. We used a nontool task to eliminate any confounds introduced by individual differences in their prior tool experience. Two groups had demonstrators (trained in isolation on different options of a four-option task, including a two-action option) and one group did not. We found that crows socially learn about context: After observers see a demonstrator interact with the task, they are more likely to interact with the same parts of the task. In contrast, observers did not copy the demonstrator’s specific actions. Our results suggest it is unlikely that observing tool-making behavior transmits tool types. We suggest it is possible that tool types are transmitted when crows copy the physical form of the tools they encounter.  相似文献

The Effect of Relationship on Children's Distributive Justice Reasoning     

Ann V. McGillicuddy-De Lisi  Cynthia Watkins  rew J. Vinchur 《Child development》1994,65(6):1694-1700

Kindergarten, third-grade, and sixth-grade children were told 2 stories about a group of children who made artwork that was subsequently sold at a craft fair. The characters in one story were described as friends, while the characters in the other story were described as strangers (relationship condition). 1 character in each story was presented as the oldest in the group, 1 as the most productive, and 1 as the poorest. Children were asked to allocate 9 dollars to the 3 characters under each relationship condition, provide rationales for those allocations, and rate the fairness of 4 different patterns of allocation. Older children allocated more money to needy friends than to needy strangers and more to productive strangers than to productive friends. Kindergartners' allocations and fairness ratings did not vary with relationship. Rationales for allocation judgements suggested that equality was the most salient principle for decisions at all ages, but the older children provided rationales based on benevolence more often than younger children when characters were presented as friends.  相似文献   

Representational Issues in Students Learning About Evaporation     

Russell Tytler  Vaughan Prain  Suzanne Peterson 《Research in Science Education》2007,37(3):313-331

This study draws on recent research on the central role of representation in learning. While there has been considerable research on students’ understanding of evaporation, the representational issues entailed in this understanding have not been investigated in depth. The study explored students’ engagement with evaporation phenomena through various representational modes. The study indicates how a focus on representation can provide fresh insights into the conceptual task involved in learning science through an investigation of students’ responses to a structured classroom sequence and subsequent interviews over a year. A case study of one child’s learning demonstrates the way conceptual advances are integrally connected with the development of representational modes. The findings suggest that teacher-mediated negotiation of representational issues as students construct different modal accounts can support enriched learning by enabling both (a) richer conceptual understanding by students, and (b) enhanced teacher insights into students’ thinking.  相似文献

Mnemonic artwork-learning strategies: Helping students remember more than “Who painted what?”     

Todd M. Franke  Joel R. Levin  Russell N. Carney 《Contemporary educational psychology》1991,16(4)

In two experiments, a recently devised mnemonic strategy was examined in the context of college students recalling the theme and contents of various paintings. With the painting-artist mnemonic strategy: (a) the artist's name is first recoded as a more concrete proxy; and (b) the recoded stimulus is then related to a prominent feature of the painting. Previous research has demonstrated that such a strategy enhances students' recall of artist names when cued with the associated paintings. The present study extends those findings by demonstrating that the strategy similarly facilitates students' recall of paintings and painting information when cued with the associated artist names. Of three different mnemonic variations included, one that incorporates a verbally described mnemonic interaction into the painting proved most effective. Suggestions for future research and educational implications are included in the discussion.  相似文献
