P. F. Lovibond and D. R. Shanks (see record 2002-00340-001) suggested that all forms of classical conditioning depend on awareness of the stimulus contingencies. This article considers the available data for eyeblink classical conditioning, including data from 2 studies (R. E. Clark, J. R. Manns, & L. R. Squire, 2001; J. R. Manns, R. E. Clark, & L. R. Squire, 2001) that were completed too recently to have been considered in their review. In addition, in response to questions raised by P. F. Lovibond and D. R. Shanks, 2 new analyses of data are presented from studies published previously. The available data from humans and experimental animals provide strong evidence that delay eyeblink classical conditioning (but not trace eyeblink classical conditioning) can be acquired and retained independently of the forebrain and independently of awareness. This conclusion applies to standard conditioning paradigms; for example, to single-cue delay conditioning when a tone is used as the conditioned stimulus (CS) and to differential delay conditioning when the positive and negative conditioned stimuli (CS+ and CS-) are a tone and white noise.

由于将来的交换存在较大的不确定性,当事人的习俗、身份、习惯等因素对契约的制定、履行有很大的作用,由此影响当事人的契约观念。因此,不同的宗族文化造就了不同的契约观念。浙北地区相对较弱的宗族意识使得浙北地区人员之间的默契和依赖的程度低,经济契约中的凭证观念相对较强。受以地缘关系为基础的依附式宗族的影响,温州人相互之间存在着较深的依附关系,这使得温州人彼此之问的交易是重内容轻形式,经济契约中的凭证观念相对较弱。 相似文献

The purpose of the present study was to examine the effectiveness and feasibility of phonological awareness training, with and without a beginning decoding component. 33 teachers in 8 urban schools were assigned randomly within their schools to 3 groups: control, phonological awareness training, and phonological awareness training with beginning decoding instruction and practice. Following training, teachers in the 2 treatment groups conducted the treatments for about 20 wks. In each teacher's class, pre- and posttreatment data were collected on 12–14 children (N?=?404); 312 children were tested again the following fall. At the end of kindergarten, the 2 treatment groups performed comparably and outperformed controls on the phonological awareness measures. On alphabetic (reading and spelling) tasks, however, the group participating in phonological awareness training with beginning decoding instruction did better than the other 2 groups. In the fall of the next year, many of these between-group differences remained but were less impressive. Implications are discussed for bridging research and practice.

Psychological mindedness and mindfulness are common themes across schools of psychotherapy. A somewhat smaller construct can be better defined: self- and relational observational capacity. This article defines and assesses strategies for 3 components of self- and relational observation: (a) awareness of feelings, ideas, and emotional control; (b) awareness of changing states of mind; and (c) awareness of self-concepts or schemas such as mental models of roles in a relationship.

Maternal alcohol consumption during pregnancy places the fetus at risk for a number of neurological abnormalities and functional impairments. These deficits are 100% preventable by abstaining from alcohol use during pregnancy. Nevertheless, the worldwide prevalence of Fetal Alcohol Syndrome (FAS), the most severe outcome of prenatal alcohol consumption, is estimated at 0.97 cases per 1,000 live births (see May & Gossage, 2001). This paper examines awareness of the problem in Canada, the United States, the United Kingdom, and Australia along three dimensions: 1) the relationship between alcohol consumption rates and the incidence of FAS; 2) government action and policy creation; and 3) prevention/intervention initiatives and educational efforts. The extent of knowledge within each country affects, and is affected by, the level of research activity, the emphasis on policy creation, and the initiatives that drive educational efforts. At present, Canada and the U.S. have the highest levels of activity and a clear recognition of the problem. Activity in the U.K. and Australia is at the grass-roots level, although some promising movements toward greater public and professional awareness have begun.

基于CNN-BLSTM的食品舆情实体关系抽取模型研究 总被引:1,自引:0,他引:1
食品舆情实体关系抽取是构建食品舆情知识图谱的关键技术,也是当前信息抽取领域的重要研究课题。针对食品舆情中常出现的实体对多关系问题,在卷积神经网络(convolutional neural network,CNN)中引入基于位置感知的领域词语义注意力机制;在双向长短时记忆(bidirectional long short-term memory,BLSTM)网络中引入基于位置感知的语义角色注意力机制,构建基于CNN-BLSTM的食品舆情实体关系抽取模型。在食品舆情数据集上进行了对比实验,实验结果表明:基于CNN-BLSTM的食品舆情实体关系抽取模型在食品舆情数据集上准确率比常用的几种深度神经网络模型高出8.7%~13.94%,验证了模型的合理性和有效性。 相似文献
