Richard C. Erickson 《Neuropsychology review》1995,5(4):223-243
This paper surveys the process approach literature with an emphasis on higher level cognitive functions like attention and concentration, learning and memory, and problem solving and executive functioning. In particular, it discusses organizational strategies and kinds of errors found on a variety of tests as well as behavioral, situational, and interpersonal issues as they relate to test procedures. It critiques the process approach and suggests future directions. 相似文献

小学儿童对虚假话语间接意义的理解 总被引:4,自引:0,他引:4
探讨了小学儿童对隐含在虚假话语中间接意义的理解特点。结果发现:(1)一年级儿童不能理解虚假话语的非字面意义,三年级儿童才基本上能够理解。(2)小学低年级儿童不能理解虚假话语的间接意义的主要原因是他们不能根据话语与事实不符和说话者知道事实真相来判断说话者说虚假话语的有意性和推论隐含的意义。部分原因可能在于他们没有意识到说话者了解事实真相,因而不知道说话者是故意使用虚假话语的。 相似文献

动词语义和句子语法对代词加工的影响 总被引:6,自引:1,他引:5
考察了动词语义和句子语法对代词加工的影响.结果表明,动词语义是影响代词理解的一个因素;相同语法功能假设尚需进一步验证,研究者还提出代词理解受社会文化因素影响的假设。 相似文献

Two studies using novel extensions of the conditioned head-turning method examined contributions of rhythmic and distributional properties of syllable strings to 8-month-old infants' speech segmentation. The two techniques introduced exploit fundamental, but complementary, properties of representational units. The first involved assessment of discriminative response maintenance when simple training stimuli were embedded in more complex speech contexts; the second involved measurement of infants' latencies in detecting extraneous signals superimposed on speech stimuli. A complex pattern of results is predicted if infants succeed in grouping syllables into higher-order units. Across the two studies, the predicted pattern of results emerged, indicating that rhythmic properties of speech play an important role in guiding infants toward potential linguistically relevant units and simultaneously demonstrating that the techniques proposed here provide valid, converging measures of infants' auditory representational units. 相似文献

句子先提述的参与者在可提取性上的优势现象 总被引:6,自引:0,他引:6
下述五个实验就汉语句子成分(包括句子的参与者及其动作)的提述次序对其可提取性的影响进行了研究,结果表明:(1)句子先提述的参与者比后提述的参与者容易被提取,提述的次序对参与者的可提取性有明显影响。(2)先提述参与者的这种优势与句子呈现的方式有一定的关系。(3)在系列呈现的条件下,先提述参与者的易提取性与探测词呈现的延迟间隔有关。(4)在系列呈现的条件下,参与者以名词形式出现时,被试的反应速度较快,而参与者以名字的形式出现时,反应则较慢;在同时呈现的条件下这种差异基本消失。(5)句子参与者的行动(即句子的动词)的提述次序对其可提取性也有明显的影响,说明提述次序对句子成分的可提取性的影响,不只限于句子参与者本身。 相似文献

The practicality of these numerical methods is demonstrated both by means of simulations and of an empirical application to the measurement of treatment effects in patients with psychosomatic disorders.The authors thank one anonymous reviewer for his constructive comments.

The use of facilitated communication with individuals with autism has generated considerable controversy over the past several years. Only recently has research begun appearing which examines the procedure using reasonable scientific controls to establish the validity of this form of communication. The present study assessed the validity of facilitated communication and evaluated the effects of facilitator influence with seven individuals with autism and mental retardation. Three individuals showed clear evidence of facilitator influence, another three showed no such influence, and one subject performed at chance levels. A follow-up session with the three subjects who showed no facilitator influence demonstrated that they also showed no unexpected language competence compared to their measured IQ and to assessment under standard conditions. Results are discussed in terms of significance for facilitated communication in general and in terms of the utility of the methodology as a means of demonstrating language competence or facilitator influence. 相似文献

5──8岁儿童对几种偏正复句的理解 总被引:5,自引:2,他引:3
本研究用三种方式测试80名5—8岁儿童对因果、条件和让步三种复句的理解。结果表明,他们对这三种复句的理解逐年提高,6岁和7岁之间的变化尤为明显。6岁儿童基本能理解因果复句和条件复句,7岁儿童基本能理解让步复句。他们在三种作业中表现出不同的理解水平,判断句子正误的成绩差于完成句子和指认代词所指的成绩。 相似文献

Assessment and treatment of covert self-injurious behavior are complicated because it is difficult to quantify and apply differential consequences to covert responses. In this study, both tangible and social reinforcers were identified using reinforcer assessment methods. These reinforcers were then provided contingent upon the absence of tissue damage identified during physical examinations, resulting in near 100% success in physical assessment checks that was maintained over 10 months. 相似文献

This study compared prototype and rote instruction of English names for Chinese visual characters. In the prototype condition, participants were taught the meaning of the prototype that served as the distinctive feature of multicomponent characters. In the rote condition, participants traced the character and wrote its translation. Participants learned more rapidly and maintained more words in the prototype condition. 相似文献
