Although the U.S. population is becoming increasingly diverse, the race of individuals entering the counseling profession remains predominantly White (S. P. Pack‐Brown, 1999). The authors define and explore the connection between White privilege and oppression and encourage the use of racial identity models to address these constructs with counselor trainees in supervision. 相似文献

Verbal and nonverbal responses by alleged victims of child sexual abuse were coded for length, amount of information, and the manner in which they were elicited by the interviewer. In 16 of the interviews, anatomical dolls were employed for the purposes of demonstration, whereas they were not used in another eight cases matched with respect to other characteristics of the children and the alleged events. Children interviewed with dolls provided an equivalent number of details and spoke as many words in the substantive portion of the interview as did children interviewed without dolls, and interviewers in the two groups used similar probes to elicit information. However, the average responses by the children were significantly longer and more detailed when dolls were not used. Children gave longer and more detailed responses to open-ended invitations when dolls were not used. Caution is necessary when interpreting these findings. 相似文献

Developmental issues in cognitive mapping: the selection and utilization of environmental landmarks 总被引:1,自引:0,他引:1
2 studies were conducted to investigate developmental differences in the ability to select and use environmental landmarks for cognitively organizing distance information from a walk. In experiment 1, second-grade, fifth-grade, and college subjects viewed a simulated walk and selected scenes that were high in potential landmark value. In experiment 2, children from the same grade levels first viewed the walk and then ranked distances among either the test scenes most frequently selected by their peers or those selected most frequently by adults. Results indicated that (a) adults and children may not spontaneously select the same features as real-world landmarks; (b) children are less capable than adults in judging the value of potential landmarks as distance cues; and (c) the ability to use environmental landmarks as cues for distance information developmentally precedes the ability to assess this potential information value. 相似文献

A new word-learning phenomenon is demonstrated and a new word-learning principle is proposed to account for it. In Study 1, 60 3-year-olds were shown a pair of objects and heard a novel label used repeatedly for one, but not for the other. In a forced-choice test of generalization of the label, the latter object was selected less often by the children than one that had not been present during training. This so-called Nominal Passover Effect was the same whether the speaker had completely ignored the comparison object during training or had referred to it with pronouns. The performance of a no-word control group ( N = 24) indicated that the effect was not due to a preference for the less exposed of the two choice objects. The effect is consistent with the Exhaustive Reference Principle, which stipulates that whenever a new generic word is used to name something, expect it to be extended to all entities in a situation that the speaker perceives and believes to be exemplars of the name. In Study 2 ( N = 48), the Nominal Passover Effect was replicated with 3 new sets of objects and with training language that contained only indefinite forms of reference. The passover experience was often sufficient to counteract children's tendency to generalize a novel label on the basis of perceptual similarity. The passover effect was not evident in free-choice name generalization tests in either study. 相似文献

In the light of challenges arising from contemporary issues such as inclusivity, sustainability and justice, the connections between art, design and caring appears to be pertinent. What role can artists and designers play in the ecology of care? How can we lead art and design students to connect and lend their creative skills to care needs? Drawing on the ethics of care and a relational view on health this article highlights the various teaching approaches and initiatives introduced at Nanyang Technological University, Singapore, to support and guide students to realise various art and design for health and wellbeing projects that provide opportunities for students to part take in ecology of care using their creative skills. Although creative explorations at the intersection of art, design and caring is still at an early stage, outcomes from this ongoing effort have been encouraging in response to the shifting social needs to create a more inclusive and flourishing society in Singapore. 相似文献

In the course of a decade of research on learning in technology‐centered classrooms, my research group has gained considerable understanding of why and how students learn science by designing technology. In this article I briefly review two dimensions in which science and technology share fundamental similarities: (a) the production and transformation of representations and (b∥ the action‐oriented language describing the two domains. Because it is fundamentally problematic to derive what ought to happen in science classrooms from other dimensions, I provide three episodes to illustrate what and how students know and learn science during technological design activities. Episodes and analyses embody the two dimensions previously outlined. Because these episodes are representative of the database established during an extensive research program, I suggest there is sufficient ground for using and investigating science‐through‐technology curricula. © 2001 John Wiley & Sons, Inc.
