返回抑制和抑制标签在长时训练下的分离

返回抑制(Inhibition of return, IOR)是指当线索-靶子的时隔大于约300 ms时, 被试对呈现在线索化位置的靶子相较对出现在非线索化位置的靶子而言反应更慢的现象。新近抑制标签 (Inhibitory tagging, IT) 理论指出, 除返回抑制外, 一个由前额叶执行控制系统负责的抑制标签机制也作用于先前线索化位置, 起着暂时中断刺激-反应链接的作用。然而, 迄今为止, 该理论的关键假设-“抑制标签一定程度上独立于返回抑制发挥作用”还未有来自常规被试研究的支持。结合线索-靶子和Stroop范式, 采用8(训练天数)×2(线索-靶子关系)×3(色字一致性)的三因素被试内实验设计, 通过连续8天的长时训练对常规被试的返回抑制和抑制标签功能在学习可塑性上的差别进行考察。结果发现, 返回抑制随着练习的增加呈现出了显著降低的趋势, 而抑制标签并未随着练习的变化而变化。研究结果表明返回抑制和抑制标签在一定程度上可以相互分离, 为抑制标签理论的关键假设提供了重要的来自常规被试的证据。     

音乐对驾驶警觉的影响及其理论模型

驾车时听音乐非常普遍。唤醒理论认为, 音乐可以使驾驶员处于最佳唤醒水平, 有利于驾驶警觉的维持。但是, 根据中枢容量有限理论, 音乐也会使驾驶员分心, 危害道路安全。动态模型在已有研究的基础上提出, 音乐对驾驶警觉起到唤醒抑或分心影响, 取决于音乐复杂性、驾驶情境要求及驾驶员个体差异等诸多因素的动态调节。最新的补偿控制理论则强调, 驾驶员自我调控是恢复动态平衡的关键。而未来的研究应关注驾驶员心理负荷的测量、智能车载音乐系统的开发以及驾驶员培训等领域。     

组织行为学研究的现状：意义与建议

本文对2008~2011年这4个年度发表在英文和中文组织行为学方面重要学术期刊上的研究进行总结, 旨在让国内学者了解现今组织行为学的现状和发展。我们在分析研究内容、研究方法的基础上, 就当前中国组织行为学研究提出了一些总结性的看法, 包括：研究问题很大程度上追随国际潮流, 但缺乏对本土重要问题的关注; 研究方法过多地集中于定量的问卷调查法, 但缺乏对多种不同方法的应用; 研究的分析层次过多地集中在个体层次上, 而对多层次的组织和团队管理现象关注不足。为更好地促进组织行为学科的发展, 本文建议：应该注重立足中国的组织和管理现象来挖掘研究问题; 采用多种研究方法, 特别应鼓励开展定性研究; 注重跨层次研究和研究的情境化等。本文通过介绍近年来组织行为领域的全面情况并详细分析其中的若干个例, 为如何克服以上不足提供具体的范例和方法。     

工作记忆负荷和自动化提取对小学生加法心算策略执行效果的影响

本研究选取43名小学四年级学生(18名男生和25名女生)为实验被试,探究了工作记忆负荷和自动化提取对复杂加法心算策略效果的影响.结果显示:(1)工作记忆负荷对复杂加法心算策略的影响显著,即一项加法心算策略所需的工作记忆负荷越小,该策略的执行效果越好;(2)自动化提取对加法心算策略的影响显著,即一项加法心算策略所需自动化提取的程度越高,该策略的执行效果越好;(3)工作记忆负荷和自动化提取对加法心算策略效果的交互作用显著,表现为在自动化提取水平较高的情况下,工作记忆负荷的大小对心算策略执行效果的影响差异不显著;而在自动化提取水平较低的情况下,工作记忆负荷小的心算策略的执行效果显著优于工作记忆负荷大的心算策略的执行效果.     

自尊研究的现状与问题

自尊概念从诞生以来一直受到不同领域研究者的广泛关注。但在诸多研究和理论的推进之下, 对于其概念内涵与外延的界定并没有达成统一, 与相关概念之间也存在一定程度的混淆与误用。研究以历史为线索, 对自尊概念发展进程中最具影响力的几种观点进行了总结与评述, 并对相关概念进行了比较与辨析。在此基础上, 研究还对现阶段自尊研究的热点话题--真实自尊的概念进行了梳理, 明确了其与虚假自尊或过分追求的自尊之间的本质差异, 即自尊的权变性与条件性, 以期为后续实证研究的展开提供依据。     

Further refinement of video‐based brief multiple‐stimulus without replacement preference assessments

We compared the results of a brief video‐based multiple‐stimulus without replacement preference assessment with no access to chosen activities (MSWO‐NO) to the results of the same assessment with access (MSWO‐WA) with four children with autism. We also compared instructor rankings of activities to MSWO‐WA results. Strong to moderate correlations between MSWO‐NO and MSWO‐WA assessment results were found across all participants. The correlation between MSWO‐WA and instructor rankings ranged from strong to low across all participants. Implications and directions for future research are discussed.     

The wrong side of history

Psychoanalysis (including analytical psychology), once a pioneering and forward‐looking movement of the early 20^th century has now become a conservative backward‐looking ‘tradition’. After considering some of the internal problems associated with this historical change such as idealization and tribalism, some ways forward are suggested – a focus on clinical excellence as practical craft, openness to the unknown and engagement with others beyond the confines of private practice.     

Revisiting Quine on Truth by Convention

In “Truth by Convention” W.V. Quine gave an influential argument against logical conventionalism. Even today his argument is often taken to decisively refute logical conventionalism. Here I break Quine’s arguments into two—(i) the super-task argument and (ii) the regress argument—and argue that while these arguments together refute implausible explicit versions of conventionalism, they cannot be successfully mounted against a more plausible implicit version of conventionalism. Unlike some of his modern followers, Quine himself recognized this, but argued that implicit conventionalism was explanatorily idle. Against this I show that pace Quine’s claim that implicit conventionalism has no content beyond the claim that logic is firmly accepted, implicit rules of inference can be used to distinguish the firmly accepted from the conventional. As part of my case, I argue that positing syntactic rules of inference as part of our linguistic competence follows from the same methodology that leads contemporary linguists and cognitive scientists to posit rules of phonology, morphology, and grammar. The upshot of my discussion is a diagnosis of the fallacy in Quine’s master critique of logical conventionalism and a re-opening of possibilities for an attractive conventionalist theory of logic.
