归纳推理的多样性效应及其机制探索

归纳推理结论范围大于前提范围的这一特点决定了归纳结论的不确定性,寻求前提的多样化是增强结论可靠度的重要途径。已有研究通过寻找证据、力度判断、特征扩展与归宿选择等研究方法发现前提类别覆盖范围、前提概率原则可以较好地解释多样性的内在机制。事实上,多样性效应的实质是大数原则在归纳推理中的运用,其产生的心理过程包括差异识别、大数信息抽取与大数信息运用三个步骤

Transfer of Reactive Inhibition

A serious challenge to Hull’s (1943) theory of reminiscence and intertrial-interval effects is posed by the current contention that reactive inhibition (I_R) must be task-specific since it does not seem to transfer from one task to another. This notion was examined within the framework of a practice-rest paradigm in which three control groups were given 20 1-min trials on a principal task with intertrial intervals of 0, 5, and 70 sec, respectively, while two experimental groups practiced alternately on the principal task and a secondary task known to produce evidence for I_R. The two secondary tasks varied in their similarities to the principal task. Additional control groups were used to assess the magnitude of habit transfer effects. The total sample consisted of 70 males and 70 females whose modal age was 18 yr. With habit transfer effects controlled, results showed clearly that work effects transferred from the alternate tasks to the main task without regard for differences in similarity. Thus, the task-specificity hypothesis was not supported.     

Foster Care Chronicles: Use of the Arts for Teens Aging Out of the Foster Care System

This article describes the use of narrative and drama therapies as creative therapeutic interventions to engage and assist vulnerable youth. Foster Care Chronicles was a collaboration between a state university social work program and a local department of social services in a child welfare unit. This 2-year exploratory project employed an innovative approach to work with foster care youth, all of whom were within 2 years of “aging out” of care. The project utilized narrative therapy and drama therapy in a group setting by building on youths’ individual and collective strengths in writing, speaking, and acting. As these youth assessed their participation in this program, their reflections addressed developing aspects of self-image, self-healing, self-efficacy, and lessons learned.     

3～5岁儿童表面与结构相似性类比推理的实验研究

采用经典类比推理问题对3~5岁儿童表面相似性与结构相似性类比推理能力进行了实验研究。结果发现:(1)表面相似性与结构相似性对儿童解决类比问题的影响不同。一般来说,前者更有利于3~5岁儿童类比问题的解决;(2)儿童解决表面相似性与结构相似性类比问题的能力随年龄增长而发展,但发展趋势不同。在表面相似性问题方面,4岁以前发展较慢,而4岁以后的发展较快;在结构相似性问题方面,4岁以前发展较快,而4岁以后的发展较慢。4岁是儿童解决类比推理问题能力的转折点;(3)在本实验条件下,工作记忆负荷对儿童解决表面相似性类比问题与结构相似性类比问题的影响不显著;(4)类比映射关系提示能促进儿童解决两类类比问题,但对不同年龄儿童的作用是非线性的。     

A FUNCTIONAL ANALYSIS OF HAIR PULLING

We experimentally assessed the functions of hair pulling and hair manipulation of a 19-year-old woman (Kris) with moderate mental retardation and cerebral palsy. In Phase 1 a functional analysis revealed that Kris pulled and manipulated hair for the greatest amount of time in the alone condition, suggesting that the behaviors were maintained by some form of automatic reinforcement (Vaughan & Michael, 1982). In Phase 2 we assessed the nature of the sensory stimulation that maintained hair pulling by providing continuous access to previously pulled or cut hair and, thereafter, by having Kris wear a rubber glove. The results suggested that hair pulling was maintained by digital-tactile stimulation (automatic positive reinforcement). These findings are discussed, and recommendations for further analyses of automatically reinforced habit behaviors are provided.
