Prelinguistic babbling often seems remarkably speech-like, not because it has recognizable words but because it seems to have adult-like prosody. To quantify this impression, we compared disyllabic sequences from five infants and five adults in terms of the use of frequency, intensity, and duration to mark stress. Significantly larger values for the three acoustic variables were observed on stressed than on unstressed syllables independent of syllable position for both groups. Adults showed the correlates of utterance final syllables--lower f0, lower intensity, and longer duration; infants showed only decrease in intensity. Ratios for stressed to unstressed syllables and participation of the three variables in stress production in individual disyllables were highly similar in both groups. No bias toward the English lexical trochaic stress pattern was observed. We conclude that infants in English environments produce adult-like stress patterns before they produce lexical items, which specify stress. Acoustic and perceptual analyses are used to explore stress marking by prelinguistic infants in an English language environment. Results show that infants employ the three acoustic correlates of stress in individual syllables in a manner largely similar to that of adult speakers, although they do not show second-syllable declination effects or an English language trochaic stress bias. 相似文献

OBJECTIVE: This study compared the effectiveness of two types of instructor feedback (relative to no feedback) on investigative interviewers' ability to adhere to open-ended questions in simulated practice interviews about child abuse. METHOD: In one condition, feedback was provided at the end of each practice interview. In the other, the instructor stopped the interviewer at various stages during the practice interviews to provide feedback. The relative effect of these conditions was examined by measuring interviewers' performance in a standardized mock interview paradigm immediately prior to, immediately after, and 12 weeks after the practice and feedback sessions. RESULTS: Prior to and 12 weeks after the practice sessions were administered, there was no significant difference in participants' adherence to open-ended questions irrespective of the nature of the feedback, or whether feedback was received. At the immediate post-practice assessment interval, however, the participants who received feedback during the practice interviews performed better (M proportion of open-ended questions=.85, SD=.13) than the other participants (post-interview feedback M=.67, SD=.18, p<.001; no feedback M=.56, SD=.16, p<.001). This heightened use of open-ended questions was associated with a greater tendency among the interviewees to provide abuse-related details in response to open-ended questions (M=.91, SD=.11) compared to the other participants (post-interview feedback M=.77, SD=.15, p<.05; no feedback M=.69, SD=.16, p=.001). CONCLUSIONS: Different types of feedback can be differentially effective in training child abuse investigators to adhere to open-ended questions. The benefits of any training program, however, are likely to be short-lived without ongoing practice. PRACTICE IMPLICATIONS: A single study compared the relative effectiveness of two types of instructor feedback (relative to no feedback) on investigative interviewers' ability to adhere to open-ended questions in simulated practice interviews about child abuse. This research is relevant to trainers of investigative interviewers because there is currently large variability in the type of feedback employed in training programs. This study is one of the first to empirically demonstrate that different types of feedback may be differentially effective in improving the performance of investigative interviewers. 相似文献

OBJECTIVE: For successful prosecution of child sexual abuse, children are often required to provide reports about individual, alleged incidents. Although verbally or mentally rehearsing memory of an incident can strengthen memories, children's report of individual incidents can also be contaminated when they experience other events related to the individual incidents (e.g., informal interviews, dreams of the incident) and/or when they have similar, repeated experiences of an incident, as in cases of multiple abuse. METHOD: Research is reviewed on the positive and negative effects of these related experiences on the length, accuracy, and structure of children's reports of a particular incident. RESULTS: Children's memories of a particular incident can be strengthened when exposed to information that does not contradict what they have experienced, thus promoting accurate recall and resistance to false, suggestive influences. When the encountered information differs from children's experiences of the target incident, however, children can become confused between their experiences-they may remember the content but not the source of their experiences. CONCLUSIONS: We discuss the implications of this research for interviewing children in sexual abuse investigations and provide a set of research-based recommendations for investigative interviewers. 相似文献

In Australia and internationally, the well-being of children and young people is a core focus of social policy, with a growing imperative to locate well-being within the sphere of education. However, the term ‘well-being’ remains ambiguous and the implementation of educational approaches to promote and improve it appears fragmented and ad hoc. In Australia, little is known about how well-being is understood and supported in schools, particularly from the perspective of students themselves. This article reports on key findings from an ambitious mixed-methods study funded by the Australian Research Council that investigated conceptualisations and practices around well-being in schools. Underpinned by theoretical interests linked to Childhood Studies and recognition theory, the research investigated policy, student and staff perspectives on well-being. The findings point to the key role of relationships, providing considerable scope for analysing the salience of Honneth’s modes of recognition for well-being in schools. 相似文献
