映射具体性和语境线索对新颖隐喻加工的影响

研究旨在考察映射具体性对新颖隐喻加工的影响及语境线索的作用,并进一步探索映射具体性高的隐喻加工困难的原因。实验1的ERPs结果发现：知觉隐喻反应时显著长于物理-心理隐喻和直接语义;两类隐喻在有语境线索下的反应时显著长于无语境线索。有语境线索的知觉隐喻比无语境线索在前部位置诱发了更负的N400成分,在中部诱发了更正的LPC成分;有语境线索的物理-心理隐喻在前部、顶部比无语境线索诱发了更正LPC成分。实验2的语义判断任务结果发现：在映射具体性不同的两类隐喻中,多映射通路隐喻的反应时均显著长于单一映射通路隐喻。总体结果支持语境线索对新颖隐喻加工的干扰效应。     

在抑制分心物干扰效应上学困生和学优生的比较

采用Stroop颜色命名作业,在严格控制各种条件下探究重复分心物的促进效应是由习惯化机制还是由分心物连续抑制机制造成的问题,进而比较学困生和学优生在Stroop干扰效应、重复分心物促进效应和负启动效应上的差异,结果显示,重复分心物促进效应是由习惯化机制造成的。这种抑制机制,只有在分心物重复条件下才能发挥作用;因而其效用并不广泛;而负启动效应所指的分心物抑制机制却是一种效用广泛的抑制机制。并进而揭示,学困生和学优生都存在重复分心物促进效应,但因学困生的负启动效应比学优生小,所以学困生在Stroop色词干扰效应上大于学优生。     

关系绩效研究

1993年,Borman和Motowidlo在组织公民行为等概念的基础上提出了关系绩效的概念,引起了广泛关注和大量实证研究。近十年的实证研究主要集中在关系绩效的构成及影响方面。概括不同研究的结果归纳为利他人行为、利组织行为、利工作行为。人格和职务特征是影响关系绩效的主要因素。关系绩效对组织的影响主要表现在促进组织绩效、人员选拔、培训以及绩效评定等方面。作者通过研究综述提出几点启示。     

员工及其管理者的情绪智力对员工工作绩效的影响

研究员工及其管理者的情绪智力对员工工作绩效的影响,并探索了管理者的情绪智力对其下属员工工作绩效发生影响的内在机制。采用配对取样的方法对30家企业进行了管理者与其下属员工的配对调查。结果发现,员工及其管理者的情绪智力对员工的工作绩效都有显著的正向影响,领导－部属交换在管理者情绪智力对员工情境绩效的影响中起部分中介作用,领导－部属交换在管理者情绪智力对员工任务绩效的影响中起着微弱的部分中介作用     

Transfer of contextual stimulus function via equivalence class development

In a conditional discrimination, 6 college students arranged six Cyrillic letters into groups of three based upon which of two additional Cyrillic letters (contextual stimuli) was present. All subjects demonstrated symmetry and transitivity within each class of equivalent stimuli. In a second conditional discrimination, two more Cyrillic letters were related to each contextual stimulus. Testing of symmetrical and transitive relations between the original contextual stimulus and the two new ones confirmed the development of two three-member classes of contextual stimuli. Subsequent tests demonstrated that the new contextual stimuli controlled the previously trained sample-comparison relations for all subjects.     

INTERACTION EFFECTS IN MULTIELEMENT DESIGNS: INEVITABLE,DESIRABLE, AND IGNORABLE

A single-subject design often used to compare the effectiveness of two or more independent variables (like treatment programs) is the multielement (alternating treatments or simultaneous treatments) design. Variants of this design approximate the concurrent comparison of the effects of two or more variables (or levels of variables) by programming the variables (or levels) in rapid alternation, typically across or within daily sessions. Properly combined with conventional reversal designs, these designs can also display a variety of interaction effects, some of them worrisome, others highly desirable for the future development of the field. A worrisome model is the possibility that when Treatment B alternates rapidly with Treatment C, the effects of each will not be the same as when each is the only treatment used. A desirable model is the use of the multielement design as a fast-paced component of an otherwise conventional reversal design examining contextual control of some relationship: the possibility that some behavior responds differently to Controlling Variables A and B in Context X than in Context Y. This second possibility opens single-subject designs to the more efficient examination of all interactive effects and is highly desirable, considering the prevalence and importance of interactions in determining the limits and the generality of currently understood behavioral phenomena.

双作业信息输入通道对作业绩效的影响

采用单作业和双作业操作,探讨了不同信息输入通道对双作业操作绩效的影响。实验结果证明：若采用相同的信息输入通道,同时操作的两种作业就会产生相互干扰,降低操作绩效;相反,若采用不同信息输入通道,双作业之间的相互干扰将减小,作业绩效得到提高。     

老年人情景记忆更新的改变：竞争记忆的回溯性干扰

记忆更新是获取新知识的一种重要能力。大量研究显示老年人情景记忆受损,但鲜有研究探讨老年人情景记忆更新模式的改变。研究在匹配了老年人和年轻人编码程度的前提下,探讨情景记忆更新的老化效应及其潜在的认知机制。我们对AB-AC记忆更新范式进行了创新,同时考察了在项目改变和位置改变条件下的老化效应,并在测试阶段纳入诱饵选项,进一步排除编码程度带来的影响。研究结果显示年轻人能对A-B和A-C记忆分离存储,而老年人更多地受到回溯性记忆干扰,即在A-B测试中出现C的闯入,并且该干扰效应显著地大于诱饵刺激带来的影响。研究结果表明,在年轻人和老年人编码程度匹配的情况下,年轻人的记忆更新通过记忆分化来实现,而老年人更多地受到竞争记忆的回溯性干扰。
