决策中后悔的ERP研究

采用运气轮博弈范式探讨后悔的加工时程。分析决策正误的ERPs发现,200～300ms决策错误比正确诱发更为负走向的波,表现为典型的FRN（feedback-related negativity, FRN）;300～400ms决策正确比错误诱发更大的P300。500～900ms决策正确比错误诱发更大的LPC（late positive component, LPC）,并表现出明显的右半球优势效应。上述结果支持了FRN加工反馈刺激显著性信息和P300加工反馈刺激效价的观点,研究发现后悔与LPC可能具有密切关联。将来研究须在控制得失程度基础上,考察FRN、P300和LPC与效价、得失及得失程度和情绪体验的关系。     

人工类别学习的认知神经研究

基于类别学习包含类别归纳、分类和认知控制3个子过程的假设, 设计了人工类别学习的新任务, 利用高密度ERP技术并结合偶极子源分析, 从纵向和横向两个方面研究了人工类别学习的神经基础与机制。结果表明, 人工类别学习涉及前扣带回、前额叶皮质和内侧颞叶等关键脑区, 并在时间序列上显示了这些脑区扮演的不同作用。基于当前发现, 我们从时-空水平上讨论了的人工类别学习的认知神经机制。     

易学与晚明小品

易学是晚明小品最重要的文化资源之一。晚明小品家的人生观、生活情趣,晚明小品理论强调小品短小、简易、新奇、独抒性灵、自然而然,皆直接或间接地吸取易学理论资源。晚明小品创作多方面受到易学的深刻影响。晚明小品兴盛也促进了易学的“小品”化。     

Delinquent Development in Dutch Childhood Arrestees: Developmental Trajectories,Risk Factors and Co-morbidity with Adverse Outcomes during Adolescence

Heterogeneity of re-offending patterns was studied in a group of 287 male early onset offenders who were first arrested before age 12. By combining data on the frequency and severity of offending as registered by the police over a 5-year follow-up period, three delinquent trajectories were identified; low, escalating, and high level re-offenders. Predicting group membership by individual and environmental characteristics known to the police at the time of the first arrest proved difficult. Compared to low level re-offenders, escalators were older and more often came from disadvantaged neighborhoods. High level re-offenders were also older at onset, more often had a non-Western ethnic background, and initially committed more vandalism. Furthermore, at the first police encounter, the police reacted more severely towards those who later became high level re-offenders. Finally, high and escalating re-offenders more often had other adverse outcomes, such as criminal victimization and Child Welfare Agency involvement.

The Effects of Reading Racetracks on the Sight Word Acquisition and Fluency of Elementary Students

The effectiveness of using the reading racetrack drill and practice intervention on the sight word acquisition and fluency of 15 elementary students was examined in two separate experiments. A multiple baseline design across participants was used. The participants were 15 third and fourth-grade students attending a public (n =10) or parochial (n =5) elementary school. Participants included children receiving special education services in a resource room, services for learning difficulties, and those in a general classroom setting. Reading racetracks IS a novel approach which employ error correction, timing, and drill and practice procedures. This strategy also utilized drill and practice probe sheets that resemble an automotive racetrack. The results indicated that during the reading racetrack intervention all of the participants more than doubled their correct rate in oral reading. There was also a marked decrease in the number of errors made by each of the participants in this study. The implications of employing reading racetrack procedures for practitioners are outlined.     

WORD GAME BINGO: A BEHAVIORAL TREATMENT PACKAGE FOR IMPROVING TEXTUAL RESPONDING TO SIGHT WORDS

Six third-grade students identified as deficient in reading skills tested the efficacy of word game bingo for acquisition and retention of sight word reading. The design was a modified multiple baseline in which treatment was implemented over 3 of 4 word sets and terminated on earlier sets when commencing treatment on later sets. Four sets of bingo cards were constructed on 7 × 9 cm paper divided into 25 equal-sized boxes. Sight words of each set were randomly placed into 24 of these boxes (the center box was marked “free”). Bingo winners were given tokens which were traded weekly for reinforcing activities. Noticeable improvements occurred for the word sets receiving the game treatment (sets A to C). Mean percentage points of improvement from baseline to treatment were approximately 30%. Terminal levels of correct responding exceeded 90%. Several variations of the game were suggested for future research and word game bingo was advocated as an effective behavioral technique for teachers to train sight word reading.     

成人晚期自我觉知的日常问题解决能力及其与日常认知的关系

本研究采用老年人日常问题解决能力测验,对１８５名被试（５１￣７６岁）予以测定。研究发现：进入成人晚期以后,自我觉知的日常问题解决能力随年龄的增长呈现出一定的下降趋势,但未表现出显著的年龄组间差异,而其个体间差异却日益明显;再有,个体自我觉知的日常问题解决能力与日常认知之间存在较为一致的变化趋势。     

Mental time travel to the future might be reduced in sleep

We present a quantitative study of mental time travel to the future in sleep. Three independent, blind judges analysed a total of 563 physiology-monitored mentation reports from sleep onset, REM sleep, non-REM sleep, and waking. The linguistic tool for the mentation report analysis is based on established grammatical and cognitive-semantic theories and has been validated in previous studies. Our data indicate that REM and non-REM sleep must be characterized by a reduction in mental time travel to the future, which would support earlier physiological evidence at the level of brain function.     

儿童外部问题行为稳定性的研究

儿童早期外部问题行为对后期的学业、行为和同伴关系以及成人期的生活都有消极的影响。探讨外部问题行为的起源、影响因素和发展机制,对考察童年期外部问题行为是否可预测将来的问题、评估干预和预防措施的必要性和有效性,都是必不可少的。文章阐述了儿童外部问题行为稳定性的有关概念,介绍了外部问题行为的发展趋势、“童年期开始的”和“青春期开始的”外部问题行为的发展路径、行为遗传学研究成果以及影响外部问题行为稳定性的因素,并指出了这类研究对治疗和干预的意义     

条件推理中否定前件下信念偏差发生阶段的ERP研究

以日常生活中的条件推理语句为实验材料,采用大、小前提和结论依次呈现的“推断-判断”范式,利用事件相关电位(event-related brain potential, ERP)技术探讨了条件推理中否定前件下信念偏差效应的脑内时程动态变化。结果发现：在行为反应上,较信念促进,信念阻碍下的正确率更低反应时更长;在脑电上,两条件(信念阻碍和信念促进)诱发的ERP波形仅在大前提加工阶段出现明显的分离。这表明该推理下的信念偏差效应可能早在对大前提的语义表征阶段就已发生。
