Three-month-old infants were trained to move an overhead crib mobile while 1 of 2 musical selections was played. Retention was assessed 1 or 7 days later in the presence of either the same music or a different musical selection. in Experiment 1, the musical selections were very different (classical versus jazz); in Experiment 2, they were much more similar (two classical pieces). Infants in both experiments displayed 1 day retention regardless of wich music was played during the retention test. At 7 days, retention was seen only when the music played during the retention test matched the training music. These data are consistent with similar findings showing that 3-month-old infants'memory is disrupted at long retention intervals when the context present during retention testing does not match the learning context. As the infant's memory wanes, context appears to function as a necessary cue for the retrieval of acquired expectancies.  相似文献   

Prevalence and demographic correlates of childhood maltreatment in an adult community sample   总被引：3，自引：0，他引：3  

Scher CD  Forde DR  McQuaid JR  Stein MB 《Child abuse & neglect》2004,28(2):167-180

PURPOSE: This study had two aims: (1) to determine the prevalence of five categories of retrospectively reported childhood maltreatment in an adult community sample and (2) to examine relationships between three theoretically and practically chosen demographic variables and childhood maltreatment. METHOD: Participants were a representative sample of 967 adult men and women in the metropolitan Memphis, Tennessee area. They completed a telephone survey that included a reliable, valid questionnaire assessing five types of childhood maltreatment (i.e., emotional abuse, emotional neglect, physical abuse, physical neglect, and sexual abuse) and demographic questions. Simultaneous logistic regression analyses were used to identify demographic correlates of specific trauma types. RESULTS: Prevalence of childhood maltreatment ranged from approximately 30% for women to over 40% for men. Approximately 13% of participants reported multiple forms of maltreatment. The most common forms of trauma for both men and women were physical abuse, physical neglect, and emotional abuse, all of which were highly likely to co-occur. Race, sex, and current educational level were each associated with an increased likelihood of childhood maltreatment; differential relationships with particular maltreatment types were also observed. IMPLICATIONS: These findings highlight the importance of research on the prevalence of and risks for multiple types of childhood maltreatment, particularly in the somewhat neglected area of emotional abuse and neglect. These findings can be used to highlight the need for preventive interventions aimed at the negative sequelae of childhood maltreatment and to tailor preventive interventions to the needs and expectations of those at high risk.  相似文献   

Studying activities that take place in speech interactions: a theoretical and methodological framework     

Valérie Saint-Dizier de Almeida  Jean-Marc Colletta  Emmanuelle Auriac-Slusarczyk  Antonietta Specogna  Jean-Pascal Simon  Gabriela Fiema 《International journal of qualitative studies in education》2016,29(5):686-713

The paper proposes a theoretical and methodological framework based on a pluralistic, concerted approach to the study of activities that take place in and through speech interactions. The framework has a general scope, applying to any collective activity taking form through language interactions. It contributes to a fuller understanding of the dynamics of activity and the emergence of the phenomena observed. The framework fits a constructivist and interactionist paradigm. It allows an approach to different dimensions of the activity: communicational, functional, discursive and interlocutory. The theories, models, concepts and methods chosen to address each of the dimensions are presented. From the study of a collaborative philosophical inquiry produced in the first year of a French primary school, we illustrate the use of the framework and show how it can be enriched according to the nature of the activity studied and researchers’ aims.  相似文献   

Analysis of lexical quality and its relation to writing quality for 4th grade,primary school students in Chile

Few studies have addressed vocabulary quality in developing writing skill in Spanish. Even less addressed it within the Chilean educational system. The specific objective of this study was to characterize, using a comprehensive set of indicators, the quality of the vocabulary produced by Chilean 4th grade students. Based on a national writing survey, a sample of 2056 texts written by 685 students was collected (narrative, persuasive, and informative texts). Current literature defines lexical quality as a composite of diverse factors that, while distinct, are interrelated. To represent the properties of the vocabulary, a set of indicators were selected: (a) lexical diversity; (b) lexical sophistication; and (c) lexical density. Using multilevel modeling (students and schools as levels 1 and 2) to explain a global writing score we found that diversity was a significant determinant for narrative and persuasive texts, density was a significant determinant for the three genres and sophistication was a significant determinant for narrative and expository text. In addition, indicators related to gender and socioeconomic conditions were only significant determinants of narrative stories. The parts of speech most often used also varied according to the purpose of each text. In all genres, words had a short extension and were very sensitive to the input presented in the stimuli. These results imply a significant challenge to this education system: how to promote the development of vocabulary in all children in order to support language learning.  相似文献   

Evaluation criteria for competency-based syllabi: a Chilean case study applying mixed methods     

Oscar Jerez  Leslier Valenzuela  Veronica Pizarro  Beatriz Hasbun  Gabriela Valenzuela  Cesar Orsini 《Teachers and Teaching》2016,22(4):519-534

In recent decades, higher education institutions worldwide have been moving from knowledge-based to competence-based curricula. One of the greatest challenges in this transition is the difficulty in changing the knowledge-oriented practices of teachers. This study evaluates the consistency between syllabus design and the requirements imposed by a competence-based learning environment. To make this comparison, the study sets four criteria (C1: explicit relationship between syllabus and graduate profile; C2: precision of the learning outcomes and assessment criteria; C3: contents that mobilise the learning outcomes; and C4: learning and assessment activities) derived from the literature and a thematic analysis of competence-based learning in higher education. Afterwards, a sample of 150 syllabi from different disciplines of five Chilean public universities were analysed, all of which stated the use of learning outcomes and competences in their learning models. Using a three-point Likert scale derived from the aforementioned criteria and their indicators, a comparison was made between the actual practices reflected in the syllabus design and the previously established criteria. Results show a gap between the declaration of a competency-based curriculum and actual syllabus outlines. Moreover, there are important differences among disciplines. Although all disciplines present high levels of accomplishment for Criteria 1 and 3, only the discipline of health sciences presents an acceptable level for Criteria 2 and 4. It is recommended that further research be undertaken towards identifying effective competency-based syllabus design.  相似文献   

Impact of federal intervention on higher education     

Dr. Ronald H. Stein 《Research in higher education》1979,10(1):71-82

One of the most serious crises currently facing institutions of higher education is federal intervention. The level which this crisis has reached is attested to by the fact that the presidents of three leading universities (Yale, Harvard, and Cornell) have in the past two years presented major reports addressed exclusively to this concern.The purpose of this article is to assess the impact of recent federal legislation and regulations on higher education. The author articulates the precepts posited in defense of such federal intervention, some of which are: financial contributions, social injustice, moral responsibility, student unrest, etc. The general costs of complying with federal laws and regulations are enumerated. In addition, the article considers the impact of a number of recent federal laws and regulations, including: Health Professions Educational Assistance Act of 1976; Copyright Law of 1976; Affirmative Action and Equal Opportunity; and Section 504 of the Rehabilitation Act of 1973. The author explores the steps that have recently been undertaken to reduce costs of complying with federal regulations and suggests additional solutions to this problem. The article concludes with a prognosis for what higher education can anticipate from the federal government and how higher education best protects its interests.Presented at the Annual Forum of the Association for Institutional Research, Houston, Texas, May 1978.  相似文献   

Demonstrator influence on observer diet preference: Effects of simple exposure and the presence of a demonstrator     

Bennett G. Galef  Deborah J. Kennett  Moni Stein 《Learning & behavior》1985,13(1):25-30

Previous studies in our laboratory have demonstrated that a naive rat (an observer), after interacting briefly with a previously fed conspecific (a demonstrator), will exhibit an enhanced preference for the diet its demonstrator had been fed. The present studies were undertaken to determine whether demonstrator-induced alterations in observer diet preference were the result of simple exposure of observers to diet-identifying cues emitted by demonstrators during the period of demonstrator-observer interaction. Our results indicated that observer experience of diet-related cues in the stimulus context provided by the presence of a demonstrator was sufficient to enhance observer preference for a diet, whereas simple exposure to that diet was not. We concluded that demonstrator influence on observer diet preferences was not the consequence of simple exposure of observers to demonstrator-emitted cues reflecting demonstrators’ diet.  相似文献
