We examined the extent to which different sounds functioned as motivating operations (MO) that evoked problem behavior during a functional analysis for two participants. Results suggested that escape from loud noises reinforced the problem behavior for one participant and escape from arguing reinforced problem behavior for the other participant. Noncontingent delivery of preferred music through sound‐attenuating headphones decreased problem behavior without the use of extinction for both participants. We discuss the results in terms of the abolishing effects of the intervention.  相似文献

Joint attention is a pivotal social communication skill often absent or impaired in young children with autism spectrum disorder. Joint attention is the shared and alternating attention of two individuals on an object or event, and has implications for later communication and social communication skills. This study used a concurrent multiple‐baseline design across 3 caregiver–child dyads to train caregivers to teach response to joint attention behaviors to their 3–6 years old children with moderate to severe autism spectrum disorder. Caregivers were trained on strategies including prompting, time delay, and elements of naturalistic teaching and implemented the intervention in brief 10‐min sessions 2–3 times per week. Results indicate parent mastery of intervention and substantial increase in child response to joint attention behaviors both prompted and independent. Implications for practice and areas for future research are discussed.  相似文献

This document presents the Bonn PRINTEGER Consensus Statement: Working with Research Integrity—Guidance for research performing organisations. The aim of the statement is to complement existing instruments by focusing specifically on institutional responsibilities for strengthening integrity. It takes into account the daily challenges and organisational contexts of most researchers. The statement intends to make research integrity challenges recognisable from the work-floor perspective, providing concrete advice on organisational measures to strengthen integrity. The statement, which was concluded February 7th 2018, provides guidance on the following key issues:
  1. § 1.
    Providing information about research integrity
     
  2. § 2.
    Providing education, training and mentoring
     
  3. § 3.
    Strengthening a research integrity culture
     
  4. § 4.
    Facilitating open dialogue
     
  5. § 5.
    Wise incentive management
     
  6. § 6.

A functional region of left fusiform gyrus termed “the visual word form area” (VWFA) develops during reading acquisition to respond more strongly to printed words than to other visual stimuli. Here, we examined responses to letters among 5‐ and 6‐year‐old early kindergarten children (N = 48) with little or no school‐based reading instruction who varied in their reading ability. We used functional magnetic resonance imaging (fMRI) to measure responses to individual letters, false fonts, and faces in left and right fusiform gyri. We then evaluated whether signal change and size (spatial extent) of letter‐sensitive cortex (greater activation for letters versus faces) and letter‐specific cortex (greater activation for letters versus false fonts) in these regions related to (a) standardized measures of word‐reading ability and (b) signal change and size of face‐sensitive cortex (fusiform face area or FFA; greater activation for faces versus letters). Greater letter specificity, but not letter sensitivity, in left fusiform gyrus correlated positively with word reading scores. Across children, in the left fusiform gyrus, greater size of letter‐sensitive cortex correlated with lesser size of FFA. These findings are the first to suggest that in beginning readers, development of letter responsivity in left fusiform cortex is associated with both better reading ability and also a reduction of the size of left FFA that may result in right‐hemisphere dominance for face perception.  相似文献

We analyzed whether institutions training physicians and advanced practice registered nurses (APRNs) have conflict of interest policies (COIP) specific to pharmaceutical relationships and if present do such policies extend to students, other clinicians, personnel, sites, and curriculum. The 2014 Association of Academic Health Centers list of US members (n=92) identified 65 eligible universities. A 10-item web-based survey was distributed to potential participants. Initial contact was to institutional Directors of Nursing Research, with sequential contacts if no response to Nursing Deans or Department Chairs, Clinical Placement Coordinators, Institutional Research Board Directors, Bioethics Departments, and Legal Counsel. Contacts received 2 email reminders before initiating the next level of contact. Reminder postcards were sent to Dean or Department Chair non-responders. 20 institutions fully completed the survey, a 30% response. Most (90%) reported COIP for continuing education or industry funded speaking but 40.5% were "unsure" or "unclear" whether this included curriculum. 55.6% were "unsure" or "did not know" if preceptors were included. Website confirmation noted COIP most frequently covered research funding or trials (95%) or gifts and meals (90%). Policies least frequently covered curriculum (10%). 25% included all clinicians in their COIP. No institution covered clinical preceptors unless they were employees. Gaps exist in knowledge of COIP and their scope related to the education of nurse prescribers. While most policies cover research funding or trials in accordance with federal law, they are not explicit or known regarding their extension to nonphysician clinicians, curriculum, or preceptors.  相似文献

本研究从三种宗教出发考查了一神论宗教的自我认知中的神圣和人类他者的表征。自我认知的概念是以叙事数据中的语义系统和情景知识为基础。考虑到认知图式形成中社会背景的重要性,本研究强调了比较宗教设计中的自我认知。样本包括60名指定的具有宗教背景的被试,对他们进行结构性访谈。在潜在语义分析(LSA)的计量模式中,通过比较自我和其它表征来绘出犹太教徒、伊斯兰教徒和基督教徒的图示。结果表明对所有的被试来说,在认知模式中的神圣表征与其父母相去甚远。与犹太教徒和基督教徒不同,伊斯兰教徒好像是以自我认知为基础来表征人性的其它方面,这种自我认知主要参考对神圣的理解。在考查计量语义空间的时候,被试通常是通过与神圣和类似人物相应的方式来表征自我的。  相似文献

Differentiating perfectionistic strivings and perfectionistic concerns, the present study examined how perfectionism predicts what coping strategies people use, when dealing with failures, and how perfectionism and coping influence people's satisfaction. A sample of 149 students completed daily reports for 3-14 days, reporting the most bothersome failure they experienced during the day, what strategies they used to cope with the failure, and how satisfied they felt at the end of the day. Multilevel regression analyses showed that perfectionistic concerns predicted more frequent use of self-blame, less frequent use of active coping and acceptance, and higher satisfaction at the end of the day, whereas perfectionistic strivings predicted less frequent use of self-blame and higher satisfaction. Although positive reframing, acceptance, and humor predicted higher satisfaction for all students, further analyses showed that positive reframing coping was particularly helpful for students high in perfectionistic concern. The findings suggest that accommodative coping strategies are generally helpful in dealing with personal failures, with positive reframing being a coping strategy that works particularly well for people high in perfectionistic concerns (who are prone to dissatisfaction) to achieve higher satisfaction at the end of the day.  相似文献

The reminiscence bump is the tendency to recall relatively many personal events from the period in which the individual was between 10 and 30 years old. This effect has only been found in autobiographical memory studies that used participants who were older than 40 years of age. The increased recall of recent events possibly obscures the reminiscence bump in the results of younger participants. In this study, a model was proposed that removes the increase for recent events from the temporal distribution. The model basically estimates a retention function based on the 10 most recent years from the observed distributions and divides the observed distributions by predictions derived from the estimated retention function. The model was examined with three simulated data sets and one experimental data set. The results of the experiment offered two practical examples of how the model could be used to investigate the temporal distribution of autobiographical memories.  相似文献

We present a set of 150 pictures with morphologically complex English compound names. The pictures were collected from various sources and were standardized to appear as grayscale line drawings of a fixed size. All the compounds had two constituents and were primarily of the noun–noun type. Following previous studies, we collected name agreement (percentage and H), familiarity, image agreement, and visual complexity norms, as well as frequency estimates for the whole compound word and its first and second constituents. These pictures and their corresponding norms (available from the Psychonomic Society's supplemental archive) are a valuable tool in the study of the morphological representation of complex words in language processing.  相似文献
