On September 2, 1997, Newfoundland transitioned from church to state control over education. Prior to this change, education had been controlled by churches. Recently, on November 9, 2000, an appeal to the Supreme Court of Canada by the Roman Catholic Church to declare the change unconstitutional was denied, settling the issue legally, although, perhaps, not politically. This article describes Newfoundland's educational system prior to the public referendum in 1997 that removed church control of education and explores some of the recent issues that have arisen since transition. It calls for further investigation into the effects of the change and the political, social, and economic forces that led to such a fundamental change.  相似文献

It is generally recognized that the ability to contemplate and communicate about the knowledge, beliefs, and goals of oneself and others is a benchmark of human cognition. Yet, little is known about the beginnings of this ability, in large measure because methods for accurately assessing very young children's ability have been unavailable. Here we present the results of using a method of convergent analyses of naturally occurring speech to assess the young child's ability to contemplate and communicate about mental state. The first study describes the frequency and function of verbs of mental reference such as think and know in the speech of one child from 2;4 to 4;0. The second examines shorter samples of speech collected from 30 two-year-olds over a 6 month period. Results from both studies suggest that the earliest uses of mental verbs are for conversational functions rather than for mental reference. First attempts at mental reference begin to appear in some children's speech in the second half of the third year. Since most of the children studied exhibited the linguistic knowledge necessary to make reference to mental states, we conclude that the absence of such reference earlier suggests that still younger children lack awareness of such states, or at the very least, an understanding of their appropriateness as topics of conversation.  相似文献

Although students with emotional disturbance are commonly known for their social behavior deficits, they often have academic deficits as well. Unfortunately, most of the intervention research and many of the practices used with this population focus upon their social behavior deficits and fail to recognize the need to improve their academic skills. Therefore, there is a need for identifying research-based interventions that focus on ameliorating social and academic deficits often exhibited by students with emotional disturbance. The purpose of this study was to examine the differential effects of self-monitoring of attention versus self-monitoring of performance on the academic and social behaviors of three minority students identified as having emotional disturbance while independently engaged in practicing mathematical calculations. The findings suggest that students with emotional disturbance may perform better socially and academically during math practice while self-monitoring their academic performance. Social validity data also suggest that students rated self-monitoring of academic performance more favorably than self-monitoring of attention. In addition, all target students in this study exhibited levels of on-task behavior more similar to their peers while self-monitoring academic performance compared to self-monitoring attentive behavior.  相似文献

Understanding how the human brain integrates features of perceived events calls for the examination of binding processes within and across different modalities and domains. Recent studies of feature-repetition effects have demonstrated interactions between shape, color, and location in the visual modality and between pitch, loudness, and location in the auditory modality: repeating one feature is beneficial if other features are also repeated, but detrimental if not. These partial-repetition costs suggest that co-occurring features are spontaneously bound into temporary event files. Here, we investigated whether these observations can be extended to features from different sensory modalities, combining visual and auditory features in Experiment 1 and auditory and tactile features in Experiment 2. The same types of interactions, as for unimodal feature combinations, were obtained including interactions between stimulus and response features. However, the size of the interactions varied with the particular combination of features, suggesting that the salience of features and the temporal overlap between feature-code activations plays a mediating role.  相似文献

It is well known that sensorimotor memories are built and updated through experience with objects. These representations are useful to anticipatory and feedforward control processes that preset grip and load forces during lifting. When individuals lift objects with qualities that are not congruent with their memory-derived expectations, feedback processes adjust motor plans to achieve successful lifts and contribute to the updating of the stored representations. The two experiments presented examine motor adaptation to an illusory size–weight lifting task, and the transfer of this motor adaptation to the unexposed hand. In Experiment 1, performers acquired motor adaptation with their right hand and transfer was measured on their left hand. In Experiment 2, adaptation was acquired with the left hand and transfer was measured on the right hand. In order to investigate the persistence of sensorimotor memories, these experiments measure adaptation, retention, and transfer after 15 min and 24 h delay periods. Both experiments confirm that experience with objects leads to adaptation of force scaling processes, that these adaptations transcend effector and are persistent. The results are discussed in terms favouring interpretations that describe motor adaptations to illusion as being centrally available.  相似文献

Research regarding semantic knowledge of objects is often conducted independently in children and adults. Review of these bodies of evidence suggests that the two literatures are often complementary. It seems critical to determine what we can learn from a developmental perspective, toward the common goal of understanding semantic organization. Here we focus on the proposal that semantic knowledge about concrete concepts may be built on the foundation of sensory/motor processes. In particular, we focus on a moderate formulation of this viewpoint, the sensory/motor model of semantic representations of objects (e.g., Gainotti 2007; Martin 2007), which has been examined utilizing behavioral, neuroimaging, and neuropsychological evidence. Taken together, behavioral and neuroimaging studies with infants, older children, and adults have suggested that patterns laid down in early childhood remain salient throughout the lifespan and may also predict patterns of deficit that emerge following brain injury.  相似文献

The current study examined the relationship between child involvement and treatment outcome in a group cognitive–behavioral treatment (GCBT) program for children with anxiety, using an adapted version of the Child Involvement Rating Scale (CIRS). Thirty-four children with a primary diagnosis of an anxiety disorder, referred for outpatient treatment at a hospital, and their parents participated in a manualized 12-session GCBT program. The Multidimensional Anxiety Scale for Children (MASC), administered at pretreatment, posttreatment, and at 4-month follow-up, served as the outcome measure. The psychometric properties of the adapted CIRS were good. Early involvement (EI) was calculated as the average score from Sessions 1 to 6 and late involvement (LI), the average score from Sessions 7 to 12. EI predicted lower MASC scores at posttreatment, after controlling for pretreatment MASC scores and for LI, B = – 1.05, t(3) = – 2.34, p < .05. EI did not predict outcomes at follow-up. Results were replicated using the original CIRS measure. Exploratory analyses suggested that the relationship between LI and treatment outcomes was moderated by medication. Involvement in therapy prior to exposures might be an important predictor of posttreatment outcomes in GCBT in a community setting.  相似文献

Functional magnetic resonance imaging (fMRI) distinguished regions of neural activity associated with active maintenance of semantic and phonological information. Subjects saw a single word for 2 sec, and following a 10-sec delay, made a judgment about that word. In the semantic task, subjects focused on the meaning of the word and decided whether a second word was synonymous with it. In the phonological task, subjects repeated the word silently and decided whether it shared a vowel sound with a nonsense word. Analyses allowed for isolation of neural activity during the maintenance delay. Semantic maintenance elicited greater activity in bilateral inferior frontal gyrus and left middle temporal gyrus regions of interest (ROI). In contrast, there was greater activity for phonological maintenance in the left superior parietal ROI. These results show a frontal-temporal network involved in actively maintaining the meanings of words, and they indicate that semantic and phonological maintenance processes are dissociable within working memory.  相似文献
