The report from President George W. Bush’s New Freedom Commission on Mental Health (NFC), Achieving the Promise: Transforming Mental Health Care in America(2003), proposes goals and recommendations for improving mental health services. This report has significant implications for the delivery of mental health services through the schools. A focused discussion of the potential opportunities and challenges of implementing NFC recommendations related to school-based mental health is presented. Strategies for addressing five key areas at the intersection of school mental health and the Commission’s recommendations include: stigma reduction, suicide prevention, expansion and improvement of school mental health, and screening and treatment of co-occurring mental health and substance abuse disorders.  相似文献

Prior research (DeLoache, Uttal & Rosengren, 2004) has documented that 18- to 30-month-olds occasionally make scale errors: they attempt to fit their bodies into or onto miniature objects (e.g. a chair) that are far too small for them. The current study explores whether scale errors are limited to actions that directly involve the child's body. We investigated whether children would also make scale errors with a doll and objects that were much too small for the doll (e.g. a chair, a bed). Many participants did try to fit the doll into or onto the miniature objects. Thus, the previously documented phenomenon of scale errors extends to situations in which the relevant size difference is between two objects. This finding supports the view that scale errors occur when visual information about object size fails to influence the decision to act on an object. The results are discussed in terms of the use of visual information for the planning and control of actions.  相似文献

We present the results of two experiments that probe the ability of rhesus macaques to match visual arrays based on number. Three monkeys were first trained on a delayed match-to-sample paradigm (DMTS) to match stimuli on the basis of number and ignore continuous dimensions such as element size, cumulative surface area, and density. Monkeys were then tested in a numerical bisection experiment that required them to indicate whether a sample numerosity was closer to a small or large anchor value. Results indicated that, for two sets of anchor values with the same ratio, the probability of choosing the larger anchor value systematically increased with the sample number and the psychometric functions superimposed. A second experiment employed a numerical DMTS task in which the choice values contained an exact numerical match to the sample and a distracter that varied in number. Both accuracy and reaction time were modulated by the ratio between the correct numerical match and the distracter, as predicted by Weber's Law.  相似文献

The author compares some critical findings of F. Mechsner and his colleagues with related results from other laboratories to point out that when higher levels of representation are available, those levels might come to be the focus of attention and control motor actions by overriding constraints at lower levels of the system.  相似文献

In this research, we investigated the effects of voice and face information on the perceptual learning of talkers and on long-term memory for spoken words. In the first phase, listeners were trained over several days to identify voices from words presented auditorily or audiovisually. The training data showed that visual information about speakers enhanced voice learning, revealing cross-modal connections in talker processing akin to those observed in speech processing. In the second phase, the listeners completed an auditory or audiovisual word recognition memory test in which equal numbers of words were spoken by familiar and unfamiliar talkers. The data showed that words presented by familiar talkers were more likely to be retrieved from episodic memory, regardless of modality. Together, these findings provide new information about the representational code underlying familiar talker recognition and the role of stimulus familiarity in episodic word recognition.  相似文献

Seminal evidence for the Mozart effect was presented by Rauscher, Shaw, and colleagues in 1993 and 1994. A critical evaluation of their methodologies and interpretation of findings raises questions that must be answered before this evidence can be regarded as valid. We discuss issues such as their scoring of the Stanford-Binet Intelligence Scale, the experimental design used in their 1993 study, the validity of their 1993 IQ measure, the duration of the Mozart effect, their choice of experimental tasks in relation to predictions of the trion model of neural functioning, and the statistical analyses and interpretation of results in the 1993 and 1994 studies.  相似文献

We provide a quantifier-free axiom system for plane hyperbolic geometry in a language containing only absolute geometrically meaningful ternary operations (in the sense that they have the same interpretation in Euclidean geometry as well). Each axiom contains at most 4 variables. It is known that there is no axiom system for plane hyperbolic consisting of only prenex 3-variable axioms. Changing one of the axioms, one obtains an axiom system for plane Euclidean geometry, expressed in the same language, all of whose axioms are also at most 4-variable universal sentences. We also provide an axiom system for plane hyperbolic geometry in Tarski's language L B which might be the simplest possible one in that language.  相似文献

This 2-year study examined the effects of early second language exposure on phonological awareness skills. Syllable, onset-rime and phoneme awareness skills of 72 anglophone children attending English or French immersion programs in primary and grade 1 were investigated. Three-way mixed ANOVAS revealed the following effects and interactions. In terms of grade effect, grade 1 students performed significantly better than primary students on phoneme and onset-rime tasks. A stimulus language effect was observed for the three levels of phonological awareness. All children performed better on English tasks than on French ones. Interaction effects of stimulus language by program were revealed for phoneme as well as syllable tasks. Posthoc analyses revealed that French students performed better on English phoneme and syllable tasks than on French, while English students performed better than French immersion students on French syllable tasks. Correlational analyses revealed significant relationships between reading and phoneme and onset-rime phonological awareness tasks regardless of program of instruction (English, French immersion) or language of reading test (English, French). Syllable awareness was only significantly correlated with the French non-word reading task for the French immersion students.  相似文献

Research regarding prevention strategies for Hispanic youth stress the importance of family interventions because of the particular importance of family as a protective factor within the Hispanic community. Starting in 1995, the Center for Substance Abuse Prevention conducted the National Cross-Site Evaluation of High Risk Youth Programs, a 5-year drug and alcohol prevention study with a sample of approximately 10,500 youth, including nearly 3,000 Hispanic youth. Youth were surveyed regarding their alcohol use patterns and risk and protective factors, with several measures of family relationships, including family connectedness, family supervision, and parental attitudes toward their child's alcohol use. Analyses indicate that family factors are highly linked to alcohol use among Hispanics, particularly among Hispanic females. Longitudinal growth curve analyses indicate that improving the connections that young Hispanic females have to their parents can have positive long-term effects on delaying or reducing their alcohol use. This evaluation was conducted under the direction of Dr. Soledad Sambrano, Ph.D. of the Center for Substance Abuse Prevention under contract #2777-95-5002 with EMT Associates, Inc. and ORC Macro. The views expressed herein represent the opinions and analyses of the individual authors and may not necessarily reflect the opinions, official policy, or position of the U.S. Department of Health and Human Services, the Public Health Service, the Substance Abuse and Mental Health Service Administration, or the Center for Substance Abuse Prevention.  相似文献

The Adolescent Transitions Program is a family-centered intervention strategy designed to reduce problem behavior and prevent drug use within a public school environment. A parent consultant within a Family Resource Center (FRC) provided universal, selected, and indicated interventions that enhanced and supported positive parenting practices known to serve as protective factors. Implementation of the 3-year FRC model involved 584 students and their families in 4 middle schools. Analyses focused on the dynamics and effects of parent consultant activities and services. Differences in school “adoption” of the FRC services were found to be a function of both passage of time and school environment. Despite significant variation in implementation across schools, FRC services significantly reduced the growth in problem behavior over the course of the middle-school years. The implications of these findings for dissemination of empirically supported, school-based, family-centered interventions are discussed.  相似文献
