Correspondence between saying and doing: Some thoughts on defining correspondence and future directions for application

Israel (1978) evaluated and discussed research on positive and negative verbal-nonverbal correspondence. In the present report we attempt to delineate the relationship of correspondence training to two major intervention goals-producing (increasing) behavior and inhibiting (decreasing) behavior. The concepts of noncorrespondence and generalized positive correspondence are introduced. Past research relating to the correspondence analyses offered for the two intervention outcomes and possibilities for future research are discussed. The relationship of verbal correspondence training to the issues of response maintenance and response generalization is also examined.     

Positive contrast, negative induction, and inhibitory stimulus control in the rat

In Experiment I, 24 rats were trained on a multiple variable-interval variable-interval schedule with a doorlight and white noise serving as component cues. Two groups were then shifted to a multiple extinction variable-interval schedule, and a third group was maintained on the multiple variable-interval variable-interval schedule. The multiple extinction variable-interval condition produced positive contrast when either the light or noise signalled extinction, and both of these cues acquired inhibitory stimulus control as measured by a combined cue test. In Experiment II, the multiple variable-interval variable-interval condition was shifted to multiple extinction variable-interval for one group, to multiple variable-time variable-interval for a second group, and was unchanged for the third group. The two experimental conditions produced identical patterns of response-rate reduction in the altered component, but the multiple extinction variable-interval condition produced positive contrast, whereas the multiple variable-time variable-interval condition did not. Subsequent combined cue and resistance to reinforcement tests revealed that the cue signalling extinction acquired stronger inhibitory stimulus control than the cue signalling variable time.     

背外侧前额叶对主动遗忘负性社会反馈的作用：针对抑郁症的TMS研究

抑郁症患者的负性心境可能源于其抑制功能障碍。患者在主动遗忘负性材料时无法有效调用背外侧前额叶(the dorsolateral prefrontal cortex, DLPFC)等负责抑制控制的额叶脑网络。同时, 患者对社会信息的加工比对非社会信息的加工存在更明显的认知神经障碍, 很难主动遗忘对自己不利的社会反馈信息。为了提高抑郁症患者对负性社会反馈的主动遗忘能力, 本研究采用经颅磁刺激技术(transcranial magnetic stimulation, TMS), 考察抑郁症患者在左侧(n = 32)或右侧DLPFC (n = 30)被激活后其记忆控制能力的改变。结果表明, 当患者的DLPFC被TMS激活时, 他们对社会拒绝的回忆正确率与健康对照组(n = 31)无差异, 且TMS激活右侧DLPFC还改善了患者对他人的社会态度。本研究是采用TMS提高抑郁症患者主动遗忘能力的首次尝试, 研究结果不但支持了DLPFC与记忆控制功能的因果关系, 还为临床治疗抑郁症、创伤后应激障碍、药物成瘾等患者的记忆控制缺陷提供了明确的神经靶点。     

工作狂领导对团队绩效的双刃剑作用机制

随着行业竞争压力的加剧, 工作狂领导在职场中愈发普遍。然而对于工作狂领导在组织中的有效性, 无论是在实践界还是在学术界都尚存争议。鉴于此, 本研究基于社会信息加工理论, 分析工作狂领导对团队绩效的双刃剑作用机制。通过对某物业管理服务公司进行多时点、多来源的问卷调查, 研究结果表明：一方面, 工作狂领导会提升团队工作卷入, 促进团队绩效; 另一方面, 工作狂领导也会引发团队消极情绪, 损害团队绩效表现; 团队工作重要性能有效缓解工作狂领导对团队绩效的消极作用, 同时促进其积极作用。以上研究发现有助于辨证理解工作狂领导有效性, 为组织培育管理人才提供有益借鉴。     

贝叶斯决策理论对复杂运动决策中运动预期的启发——以网球和足球为例

对运动决策的研究是认知运动心理学的一个重要领域。运动预期被认为是运动决策的核心, 受到运动学和非运动学信息的影响。其中, 对运动预期研究的一个关键问题是探讨不同信息源对运动结果预期的贡献以及两者之间的相互作用。研究者运用贝叶斯决策理论解释运动预期中不同信息的整合过程, 分析运动员在复杂的竞赛情景中如何做出最佳决策, 尤其是对该理论在网球和足球领域的潜在应用进行分析。在不确定的情况下, 竞技体育中并非所有的选择、结果或概率都是已知的, 故有研究者认为概率论和经典的决策理论不能有效解决此类问题。然而新近提出的启发式近似, 为运动员在贝叶斯框架下如何快速做出选择提供了理论依据：首先, 在复杂和有时间压力的竞赛情景中, 启发式近似假设运动员依据竞赛中不同信息源的不确定程度, 很可能选择在运动学信息和情境先验之间进行切换启发式, 提高运动预期的效率。其次, 判断效用通过卷积效应影响两种信息源的整合, 降低情境先验的影响程度。     

社会评价影响错误后调整效应

现有研究主要采用结果评价或结果反馈的方式考察评价对错误后调整效应的影响,但是任务前的社会评价怎样影响错误后调整效应尚不清楚。本研究采用社会评价任务,以错误后反应时和错误后正确率为指标,在两个实验中考察正性和负性评价对错误后调整效应的影响。结果发现,实验1和实验2中正性和负性评价条件下错误后减慢效应差异均不显著,说明正性和负性评价对错误后调整的作用是一致的,且不受实验任务的影响。在实验1中通过和无评价条件比较发现,评价条件下的正确后反应显著慢于无评价条件,但是评价条件下的错误后反应与无评价条件无差异,说明社会评价加速了个体错误后调整。而且在实验2中发现高低自我效能组个体错误后调整效应差异不显著,说明当前结果不受个体自我效能感的影响。因此,当前研究说明任务前的社会评价促进了个体错误后行为调整,但是错误后调整效应不受社会评价效价的影响。     

生涯适应力与择业焦虑：注意偏向和归因的认知加工作用

为了探讨生涯适应力与择业焦虑的关系及内部的认知加工过程。采用点探测范式测量注意偏向,问卷法调查大学生的生涯适应力、归因和择业焦虑。结果发现：（1）生涯适应力既能直接负向预测择业焦虑,又能通过积极事件归因方式、及注意偏向和积极事件归因方式的链式中介作用间接预测择业焦虑。（2）在生涯适应力与择业焦虑的关系中受到消极事件归因方式的调节作用：只有消极事件积极归因时,生涯适应力才会影响择业焦虑。研究结果揭示了择业焦虑的内部作用过程,丰富了生涯适应力通过注意偏向和积极事件归因方式影响择业焦虑的解释视角,为通过归因和注意偏向的调整缓解不同生涯适应力个体择业焦虑提供了重要参考。     

The effects of negative reinforcement for irritable aggression on resident-intruder behavior

This experiment demonstrated that rats trained to display elevated levels of shock-induced aggression in a negative reinforcement paradigm displayed more boxing behavior than yoked control groups in a later test in which intruder rats were placed in the home cage of resident rats. Resident or intruder status did not affect the influence of the negative reinforcement procedure on the observed resident-intruder behavior of trained animals; however, naive intruders paired with trained residents displayed increased defensive behavior, suggesting that negative reinforcement for shock-induced aggression affected the behavior of these residents.     

Is the news making us unhappy? The influence of daily news exposure on emotional states

There is evidence that exposure to negative news is making people feel bad, but not much is known about why this only affects some people or whether this also applies to everyday news exposure. This study examined the direct and indirect effects of daily news exposure on people's affective states. Using ecological momentary assessment (EMA), 63 respondents (24 men and 39 women) reported their news exposure and affective states five times a day for 10 days. In addition, personal relevance of the news and personality characteristics, neuroticism and extraversion, were assessed. Results showed that negative news perceptions were related to more negative affect and less positive affect, and these effects were moderated by personal relevance, but not personality characteristics. The implications of these outcomes are discussed.
