IAT效应在不同目标概念水平上的差异研究

采用IAT实验设计,考察大学生对不同概念词的内隐态度之间的差别。结果发现,八组实验材料都产生了显著的IAT效应;不同性别的测验材料的IAT效应间不存在显著差异,不同喜好程度的测验材料的IAT效应间存在显著差异,且两个因素存在显著的交互作用。研究表明,IAT效应既可在上位概念水平上产生,亦可在下位概念水平上产生。     

Is “Latin American Thought” Philosophy?

Abstract: A durable question in Latin American thought is whether it could amount to a characteristically Latin American philosophy. I argue that if, as is now widely conceded, there is a role for philosophical analysis in thinking about problems that arise in applied subjects, such as bioethics, environmental ethics, and feminism, then why not also in Latin American thought? After all, the focus of Hispanic thinkers has often been upon the issues that arise in their own experiences of the world, and they make up a diverse group of peoples related by very idiosyncratic ethnic and historical connections. I believe that, given some appropriate criteria, the existing corpus of works by Latin American thinkers is a part of a distinctive philosophy.     

Rejoinder to Harold Blum2

The author's main disagreement with Harold Blum is over Blum's contention that symptomatic improvement is directly linked to the recovery of memories. The idea that memories are laid down in childhood and preserved until the time of their later recovery flies in the face of what we now understand as the creation of memories by the neurobiological systems underpinning this aspect of mental function. No evidence directly links symptomatic improvement to reconstruction and thus to outcome; care should be taken to avoid confusing co‐occurrence with causality. While reconstruction of how things actually were in childhood can significantly contribute to therapeutic action, it is the process rather than the outcome of this reconstruction that is therapeutic, due to the opportunity thus afforded to rework current experiences in the context of other perspectives. The author clarifies his definition of transference to show some areas of agreement between his position and Blum's. He disusses contemporary neuroscientific views on memory and identifies a number of psychoanalytic writers who have used these productively.     

过去经验对内隐社会知觉的影响

通过选择不同年代的大学生被试以及不同年代的浒词材料对“经验”变量进行了实验操作;同时,采用“意识过滤技术”一速示辨认测验对内隐社会知觉的特点进行了考察;结果发现,实验材料双字词原笔划数,被试的性别对内隐社会知觉没有影响,而经验对内 有显著的影响,此外,还证明示测验作为间接测量方法是比较“纯净”的,没有受到意识的“污染”。     

在内隐学习条件下任务难度对于判断准确率的影响

本研究利用自行设计的复杂规则产生出不同难度的任务系统,进而通过实验阐明了内隐学习的三个特征;（一）在任务难度极大的情况下,内隐学习并不发挥作用;（二）在任务难度降低到一定程度的时间,内隐学习开始发挥作用,这仿佛是一个“阈限”;（三）随着任务难度逐渐降低,内隐学习的效率也随着提高,但是最科停止在一个较高的水平而再继续上升,可以间接推断,内隐学习获得了样例的具体信息。     

Implicit sequence learning in ring‐tailed lemurs (Lemur catta)

Implicit learning involves picking up information from the environment without explicit instruction or conscious awareness of the learning process. In nonhuman animals, conscious awareness is impossible to assess, so we define implicit learning as occurring when animals acquire information beyond what is required for successful task performance. While implicit learning has been documented in some nonhuman species, it has not been explored in prosimian primates. Here we ask whether ring‐tailed lemurs (Lemur catta) learn sequential information implicitly. We tested lemurs in a modified version of the serial reaction time task on a touch screen computer. Lemurs were required to respond to any picture within a 2 × 2 grid of pictures immediately after its surrounding border flickered. Over 20 training sessions, both the locations and the identities of the images remained constant and response times gradually decreased. Subsequently, the locations and/or the identities of the images were disrupted. Response times indicated that the lemurs had learned the physical location sequence required in original training but did not learn the identity of the images. Our results reveal that ring‐tailed lemurs can implicitly learn spatial sequences, and raise questions about which scenarios and evolutionary pressures give rise to perceptual versus motor‐implicit sequence learning.     

Servant leadership and employee outcomes: the moderating role of subordinates’ motives

Drawing from implicit leadership theories we advance servant leadership theory by examining moderating mechanisms that explain under what conditions servant leader behaviours impact followers in organizations. Specifically, we focused on the moderating role of subordinates’ motivational orientations—prosocial values or impression management motives—in relationships between servant leadership behaviours and job satisfaction, as well as subordinate organizational citizenship behaviours (OCBs). Using time-lagged data collected from 192 supervisor-subordinate dyads, we found that servant leadership was positively associated with employees’ job satisfaction, but not significantly related to their performance of OCBs. We also found evidence that subordinates’ motives moderate the relationships between servant leadership and outcomes. Specifically, employees high on impression management experienced lower levels of job satisfaction than their lower scoring counterparts. Our findings suggest that servant leadership may not be equally beneficial for all followers. We discuss implications for theory and practice.     

Route learning in Korsakoff's syndrome: Residual acquisition of spatial memory despite profound amnesia

Korsakoff's syndrome (KS) is characterized by explicit amnesia, but relatively spared implicit memory. The aim of this study was to assess to what extent KS patients can acquire spatial information while performing a spatial navigation task. Furthermore, we examined whether residual spatial acquisition in KS was based on automatic or effortful coding processes. Therefore, 20 KS patients and 20 matched healthy controls performed six tasks on spatial navigation after they navigated through a residential area. Ten participants per group were instructed to pay close attention (intentional condition), while 10 received mock instructions (incidental condition). KS patients showed hampered performance on a majority of tasks, yet their performance was superior to chance level on a route time and distance estimation tasks, a map drawing task and a route walking task. Performance was relatively spared on the route distance estimation task, but there were large variations between participants. Acquisition in KS was automatic rather than effortful, since no significant differences were obtained between the intentional and incidental condition on any task, whereas for the healthy controls, the intention to learn was beneficial for the map drawing task and the route walking task. The results of this study suggest that KS patients are still able to acquire spatial information during navigation on multiple domains despite the presence of the explicit amnesia. Residual acquisition is most likely based on automatic coding processes.     

内隐和外显记忆任务之间的实验性分离:编码程度和提取要求的作用

通过操纵编码程度(实验1)和提取要求(实验2)比较了内隐和外显记忆任务之间的操作变化.结果表明,编码时的语义和非语义加工之间存在着相互抑制的倾向;提取要求中更多意识成份的参与使先前情节中的语义成份得到更多的提取,而很少影响非语义成份的提取,编码程度和提取要求之间存在着相互作用.     

内隐记忆和内隐学习的整合研究趋向

内隐记忆和内隐学习代表了人类学习与记忆的无意识机制,它们打开了理解人类无意识奥妙的大门。从内隐记忆和内隐学习的诞生与实验室发展来看,二者似乎长期以来处在相对独立的位置。然而,随着研究的不断深入,走向整合已经成为不可抑制的趋向。该文旨在结合内隐记忆和内隐学习的定义、经验类似性、理论框架和实验研究等方面的证据,论述它们的整合必要以及已有的整合途径,促进研究对学习和记忆的无意识过程的全面把握
