Does matching up features mess up job choice? Boundary conditions on attribute‐salience effects

Research in decision making has suggested that the degree to which features of an option are shared versus unique influences preferences in a way that violates normative rules. The generalizability of these findings to job choice was investigated. Senior‐level, undergraduate job seekers (N = 216) were presented with three jobs from which they were asked to choose one. Attributes for two of the jobs (A and B) remained invariant across conditions, and attributes for a third job (C) were manipulated such that it shared unfavorable features with one of the invariant jobs (A or B) and favorable attributes with the other job (B or A). Results suggested that jobs with unique positive features and shared negative features were preferred over those with unique negative features and shared positive features only when information was presented in a simple (versus complex) format and when participants did not rate the importance of attributes prior to the choice task. We suggest that inferences from feature‐matching research should be qualified by these boundary conditions. Copyright © 2002 John Wiley & Sons, Ltd.     

成人在语境中的母语词汇意义学习

语境学习是成人获得词汇意义的主要方式, 大量研究者使用语境学习范式考察成人母语词汇意义学习的问题。已有研究将词汇意义学习分为两大阶段：习得词汇的对应概念阶段和将新词的意义整合到已有的语义网络中的阶段。基于词汇意义学习两大加工阶段中语境学习的相关研究, 梳理了词汇、语境、被试因素对成人词汇意义学习的影响, 指出未来研究需要进一步关注新概念学习、隐喻意义学习等问题。     

A method for increasing empirical discriminability and eliminating top‐row preference in photo arrays

It is important to consider the two parameters of signal detection theory, discriminability and response bias, when evaluating eyewitness identification from simultaneous lineups. On the basis of the diagnostic feature‐detection hypothesis, we tested a method for increasing discriminability that encourages eyewitnesses to carefully rank each lineup member based on match to their memory for a perpetrator. This procedure increased empirical discriminability and also eliminated a response bias that is largely overlooked in the literature: Participants were biased to choose from the top row of the six‐pack (2 × 3) lineup commonly used in the United States. We argue that suspect position in the simultaneous lineup is an important variable to consider for researchers and the criminal justice system. We also encourage researchers to test the ranking procedure to determine if such a simple set of instructions could be utilized by police to help eyewitnesses correctly sort innocent versus guilty suspects.     

主题关系对无线索回忆再认效应的影响

本研究采用RWCR范式,从无线索回忆再认的视角考察了主题关系对熟悉性的影响。结果发现,主题关系能够引发无线索回忆再认效应。具体表现为,在回忆错误项目中,被试对与学过项目有主题关系线索的熟悉性评分显著高于与学过项目无主题关系线索的熟悉性评分。这一结果表明,个体在信息提取失败时,概念形式的语义信息也能引发基于熟悉性的再认判断。     

对归纳推理非对称性现象的特征迁移解释

作者创新提出对归纳推理非对称性现象的特征迁移解释,认为根据由前提类别已知的特征集合构成的特征样本中迁移出现在结论类别中的特征的比例,能预测作为新特征的归纳特征由前提类别迁移到结论类别的可能性。以大学生为被试的实验结果支持对非对称性现象的特征迁移解释而不是原来的两种相似性解释。     

视觉工作记忆中的子系统

由于在预实验中发现记忆复合物体(multi—feature objects)时存在子系统优势,在本实验中,研究了记忆单特征物体(single—feature objects)时,是否存在子系统优势。被试为中国科学技术大学学生17人。要求被试记忆同样数目的单特征物体,条件1下物体属性相同,条件2下物体分属两种属性。通过正确率分析,条件2的成绩好于条件1。这个结果表明：单特征物体记忆时存在子系统优势。     

The development of explicit memory for basic perceptual features

In three experiments with 164 individuals between 4 and 80 years old, we examined age-related changes in explicit memory for three perceptual features--item identity, color, and location. In Experiments 1-2, feature recognition was assessed in an incidental learning, gamelike task resembling the game Concentration. In Experiment 3, feature recognition was assessed using a pencil-and-paper task after intentional learning instructions. The form of the explicit memory function across the life span varied with the particular perceptual feature tested and the type of task. Item recognition was excellent at all ages but was significantly poorer for older adults than children, color recognition peaked in late childhood on the gamelike task, and location recognition peaked in early adulthood on the pencil-and-paper task. These findings indicate that performance on explicit memory tests is not a consistent inverted U-shaped function of age across various features. Explicit memory performance depends on what is measured and how. Because explicit memory typically reflects a composite of different features, age-related changes in explicit memory will not necessarily correspond to the function for any single one.     

Visual working memory for dynamic objects: Impaired binding between object feature and location

In daily life, people frequently need to observe dynamic objects and temporarily maintain their representations in visual working memory (VWM). The present study explored the mechanism underlying the binding between perceptual features and locations of dynamic objects in VWM. In three experiments, we measured and compared the memory performance for feature-location binding of multiple dynamic and static objects. The results showed that the feature-location binding was impaired for the dynamic objects compared with the static objects. The impairment persisted when the global spatial configuration of the objects remained intact during the motion, as well as when the binding task was relatively easy, such as binding between single-feature objects and coarse locations. The results indicate that object features and locations are not maintained in VWM as well-integrated object files; rather, the formation of feature-location binding may require additional processes, which are disrupted by the constant change of locations in dynamic circumstances. We propose a consolidation process as possible underlying mechanism, and discuss factors that may influence the strength of feature-location binding in dynamic circumstances.     

Both associative activation and thematic extraction count,but thematic false memories are more easily rejected

The main aim of this study was to analyse the roles played by associative activation and thematic extraction in the explanation of false memories using the Deese, Roediger, McDermott (DRM) paradigm. Associative lists with two different types of critical items (CIs) were used: one, the associative CI, corresponded to the word most strongly primed by the associates in the list and another, the thematic CI, was the word that best described the theme of the list. Following three different types of encoding instructions (standard, warning or strategic), false recognition for these two types of CIs was analysed in either self-paced or speeded response recognition tests. The results showed considerable levels of false memories for both types of CIs. Even without the quality of being “good themes”, associative CIs produced high levels of false recognition, which suggests that associative activation plays a prominent role in false memory formation. More interestingly, thematic CIs were more prone to be edited out, reinforcing the argument that thematic identifiability has a major role in the rejection of false memories.     

Model of Occupational Empowerment and Gunnarsson’s Tree Theme: Intervention for Mothers in Recovery

In this study the authors investigated Gunnarsson's Tree Theme Method as an occupational therapy intervention program for mothers in recovery from addiction in accordance with Fisher and Hotchkiss's Model of Occupational Empowerment (2008 Fisher , G. , &; Hotchkiss , A. ( 2008 ). A model of occupational empowerment for marginalized populations in community environments . Occupational Therapy in Health Care , 22 , 55 – 71 . Retrieved from EBSCOhost .[Crossref] , [Google Scholar]). Each session of this mixed design study consisted of relaxation exercises, discussions on self-help readings, and participation in the Tree Theme Method. Two participants out of three improved their personal growth initiative. Participant reflection provided insight into the women's inner feelings. Fisher and Hotchkiss's model (2008 Fisher , G. , &; Hotchkiss , A. ( 2008 ). A model of occupational empowerment for marginalized populations in community environments . Occupational Therapy in Health Care , 22 , 55 – 71 . Retrieved from EBSCOhost .[Crossref] , [Google Scholar]) was supported as the women achieved personal growth. Further research is needed concerning how this may guide occupational therapy practice with disadvantaged populations.
