家校合作对青少年学业成绩的影响：一个有调节的中介模型

本研究基于广州市基础教育质量监测项目,以2380名初中生及其家长为被试,构建一个有调节的中介模型,考察了家校合作对青少年学业成绩的影响机制。研究发现：（1）家校合作对青少年学业成绩具有显著的正向预测作用;（2）在家校合作对青少年学业成绩的影响中,亲子沟通发挥了部分中介作用;（3）独生状况调节了家校合作→亲子沟通→学业成绩的后半段,即相对于非独生子女而言,独生子女亲子沟通对学业成绩的促进作用更为显著。     

效度概化的理论研究述评

效度概化（validity generalization：VG）是心理测量理论和元分析的结合体,也是元分析在人事测评领域的重要应用。它深刻地挑战了人事测评效度的情景特异论,在工业与组织心理学的发展历程当中具有里程碑意义。该文系统地介绍了效度概化理论的逻辑思路、主要模型、关键理论语与应用,以及研究趋势。     

Generalization of conditioned fear-potentiated startle in humans: experimental validation and clinical relevance

Though generalization of conditioned fear has been implicated as a central feature of pathological anxiety, surprisingly little is known about the psychobiology of this learning phenomenon in humans. Whereas animal work has frequently applied methods to examine generalization gradients to study the gradual weakening of the conditioned-fear response as the test stimulus increasingly differs from the conditioned stimulus (CS), to our knowledge no psychobiological studies of such gradients have been conducted in humans over the last 40 years. The current effort validates an updated generalization paradigm incorporating more recent methods for the objective measurement of anxiety (fear-potentiated startle). The paradigm employs 10, quasi-randomly presented, rings of gradually increasing size with extremes serving as CS+ and CS−. The eight rings of intermediary size serve as generalization stimuli (GSs) and create a continuum-of-similarity from CS+ to CS−. Both startle data and online self-report ratings demonstrate continuous decreases in generalization as the presented stimulus becomes less similar to the CS+. The current paradigm represents an updated and efficacious tool with which to study fear generalization—a central, yet understudied conditioning-correlate of pathologic anxiety.     

Learning generalization in problem solving by a blue-fronted parrot (<Emphasis Type="Italic">Amazona aestiva</Emphasis>)

Pepperberg (The Alex studies: cognitive and communicative abilities of gray parrots. Harvard University Press, Cambridge;1999) showed that some of the complex cognitive capabilities found in primates are also present in psittacine birds. Through the replication of an experiment performed with cotton-top tamarins (Saguinus oedipus oedipus) by Hauser et al. (Anim Behav 57:565-582; 1999), we examined a blue-fronted parrot's (Amazona aestiva) ability to generalize the solution of a particular problem in new but similar cases. Our results show that, at least when it comes to solving this particular problem, our parrot subject exhibited learning generalization capabilities resembling the tamarins'.     

The Level of Detail in Infants' Word Learning

ABSTRACT— This article summarizes recent findings on infant word learning and recognition. Infants initially store very detailed representations of words, including details that are not truly necessary for word recognition. As they are exposed to more varied productions of words, they develop more sophisticated knowledge about which details are important, and streamline their representations, allowing them to better recognize words across different contexts, speakers, and environments.     

真实线和想象线的朝向辨别学习及其相互迁移

以往的朝向辨别学习普遍采用真实刺激作为材料,其特异性与迁移性是研究争论的焦点之一。该研究以实线和想象线为刺激,采用朝向辨别任务训练被试,系统考察两者朝向辨别学习的特点和相互关系。结果发现,训练实线和想象线任务的两组被试行为都有显著提高,并且这两种学习效果能部分地彼此迁移,且都能迁移到不同位置。该研究结果提示,不论是想象线的学习还是实线的学习都涉及高级脑区的参与,并且两者的学习有部分共同的脑机制。

运用排列和组合原理,通过三个实验研究了样例解题步骤的编码方式对原理运用的作用.实验1和实验2分别探讨了样例解题步骤的不同编码方式对解决表面概貌变化和表面对应变化的新问题时原理运用的影响;实验3探讨了不同编码条件下原理运用概化的形成.结果表明:用子目标编码样例的解题步骤有利于消除新问题解决中由于表面概貌和表面对应变化带来的消极影响;用子目标编码样例的解题步骤促进了学习者对原理的理解和获得原理的概化图式.     

信度的再认识与信度概括化研究

本文首先对信度概念进行了明确,指出信度是评价测验结果可靠与否的一个指标,而不是测验工具的不变属性。针对测验结果的信度估计的可变性,介绍了上世纪末Vacha-Haase提出的信度概括化研究方法．即一种用来探索得分信度估计的可变性、并对引起变异的预测源进行探讨的一种元分析方法。最后通过对信度概括化研究手段的分析,指出信度概念的再认识与信度概括化研究将会给心理测验工作者带来新的启示。     

TEACHING RECEPTIVE NAMING OF CHINESE CHARACTERS TO CHILDREN WITH AUTISM BY INCORPORATING ECHOLALIA

The facilitative effect of incorporating echolalia on teaching receptive naming of Chinese characters to children with autism was assessed. In Experiment 1, echoing the requested character name prior to the receptive naming task facilitated matching a character to its name. In addition, task performance was consistently maintained only when echolalia preceded the receptive manual response. Positive results from generalization tests suggested that learned responses occurred across various novel conditions. In Experiment 2, we examined the relation between task difficulty and speed of acquisition. All 3 participants achieved 100% correct responding in training, but learning less discriminable characters took more trials than learning more discriminable characters. These results provide support for incorporating echolalia as an educational tool within language instruction for some children with autism.     

Cover, Copy, and Compare: A Self-Managed Academic Intervention Effective Across Skills, Students, and Settings

Cover, Copy, and Compare (CCC) is a simple, efficient, self-managed academic intervention that can be used to improve accuracy, fluency, and maintenance across students, curricula objectives, academic skill domains, and settings. In it's simplest form CCC requires students to look at an academic stimulus (e.g., for spelling the stimulus would be a written a word) cover the stimulus, respond by copying the stimulus (e.g., writing the word), and evaluate the responses by comparing it to the original stimulus. The CCC procedure and research that supports the generalizability and ecological validity of this procedure is described and analyzed. Following this analysis, recommendations for implementing Cover, Copy, and Compare in educational settings are provided.
