Forced-choice and conventional personality assessment: Each may have unique value in pre-employment testing

Forced-choice (FC) personality scales are purported to predict criteria such as counterproductive work behavior (CWB) incrementally beyond conventional personality measures in pre-employment testing situations. Unfortunately, the research upon which FC tests’ claims of superiority are founded, relies upon undergraduate participants in highly artificial scenarios. Moreover, the possible predictive advantages of FC personality scales with regards to important contextual performance (CP; Borman & Motowidlo, 1993) criteria have not been investigated. We used a sample of call center employees to investigate the incremental validity of a FC personality scale over a conventional personality scale (and vice versa) with CP measures, and CWB, as criteria. Our FC and conventional personality measures were highly correlated, but each still offered unique predictive value with regards to CP or CWB. Thus, contrary to past research with student samples, in field settings FC personality scales may not be clearly superior to conventional personality scales. Moreover, contrary to widespread concern that FC measures’ predictiveness is attributable to their overlap with general mental ability, the unique predictive value of our FC measure remained even when variance due to general mental ability was statistically controlled.     

儿童对所属同伴团体的选择和适应

为探讨儿童所属非正式同伴团体的选择和适应过程,选择469名小3、初1学生参加了为期2年的追踪研究.儿童同伴团体和学校适应(社会行为、社会适应、学习适应)的资料取自包含同伴评定、教师评定和学校记录多种渠道.研究发现,(1)儿童选择与自己在学校适应方面相似的同伴组成同伴团体;(2)同伴团体不仅在成员构成还是在学校适应的团体特征上具有中等程度的稳定性;(3)儿童在初测时所属同伴团体的社会能力越强、社交性越高、学业成绩越优异,则其两年后在这些方面的表现也越好,如果所属同伴团体存在同伴拒绝或学业问题,则儿童在两年后被同伴拒绝和出现学业问题的可能性也越大.     

延迟命名任务中图词干扰效应的眼动研究

采用图-词分离呈现及眼动技术探讨在延时命名条件下图-词干扰效应发生的位置。结果发现：（1）延时命名图片时,仍出现图-词干扰效应和频率效应;（2）与命名干扰词相比,命名图片时图片的回视率高,注视时间长;（3）图片的注视时间也出现频率效应和图-词干扰效应。这说明即使在延时命名图片的条件下,目标词汇仍需要再次激活,频率效应和图-词干扰效应是发生在词汇化过程中,反驳反应排除理论的图-词干扰反应选择阶段的观点,支持了词汇化选择竞争的理论。     

双语言语产生中的词汇提取机制

文章主要介绍了双语言语产生中词汇提取机制的两种理论：非特定语言提取的理论和特定语言提取的理论。重点围绕着双语言语产生中词汇提取的一个关键问题,即非目标语言的词汇是否对目标语言的词汇提取形成竞争或者干扰详细地论述了二者的理论分歧,非特定语言提取的理论认为非目标语言的词汇会对目标语言的词汇提取形成竞争,而特定语言提取的理论认为不会形成竞争。文章最后介绍了双语言语产生中词汇提取机制的最新研究趋势,表明了非特定语言提取的理论和特定语言提取的理论逐步走向融和     

工作记忆在简单整式和判断中的作用

选择20名大学二年级数学系的学生作为被试,要求他们完成控制条件、语音任务、手动击键任务和随机间隔决策任务条件下的简单整式和等式判断任务,实验结果表明:(1)三种次级任务均非常显著影响真假等式的反应时,(2)三种次级任务对真假不等式判断的错误率产生了不同程度的影响。这说明,语音环路、视空间模板和反应选择成分参与简单整式和判断,而且真假等式判断需要不同的注意资源。     

大学生友伴选择标准及其友伴关系

从湖南两所大学选取297名大学生为被试,采用定性研究的方法探讨大学生友伴选择的影响因素,并制定友伴选择标准调查问卷,然后再从湖南一所大学选取1166名大学生为被试,采用定量研究的方法对大学生友伴选择标准及其友伴数量、友伴关系质量之间的关系进行调查。结果发现:大学生在友伴选择标准方面可以归为完美型、适度型和低要求型3种类型;不同类型在性别、年级、专业上的分布存在显著差异;适度型大学生的友伴数量显著多于完美型;完美型、适度型大学生在与友伴的帮助与支持、与友伴的冲突方面显著多于低要求型,完美型在与友伴的冲突强度上也显著大于低要求型。     

Guided search through memory

In “hybrid” search, observers search a visual display for any of several targets held in memory. It is known that the contents of the memory set can guide visual search (e.g., if the memorized targets are all animals, visual attention can be guided away from signs). It is not known if the visual display can guide memory search (e.g., if the memory set is composed of signs and animals, can a visual display of signs restrict memory search to just the signs?). In three hybrid search experiments, participants memorized sets of items that belonged to either one or several categories. Participants were then presented with visual displays containing multiple items, also drawn from one or several categories. Participants were asked to determine if any of the items from their current memory set were present in the visual display. We replicate the finding that visual search can be guided by the contents of memory. We find weaker, novel evidence that memory search can be guided by the contents of the visual display.

Do people treat missing information adaptively when making inferences?

When making inferences, people are often confronted with situations with incomplete information. Previous research has led to a mixed picture about how people react to missing information. Options include ignoring missing information, treating it as either positive or negative, using the average of past observations for replacement, or using the most frequent observation of the available information as a placeholder. The accuracy of these inference mechanisms depends on characteristics of the environment. When missing information is uniformly distributed, it is most accurate to treat it as the average, whereas when it is negatively correlated with the criterion to be judged, treating missing information as if it were negative is most accurate. Whether people treat missing information adaptively according to the environment was tested in two studies. The results show that participants were sensitive to how missing information was distributed in an environment and most frequently selected the mechanism that was most adaptive. From these results the authors conclude that reacting to missing information in different ways is an adaptive response to environmental characteristics.     

Rethinking volitional control over task choice in multitask environments: Use of a stimulus set selection strategy in voluntary task switching

Under conditions of volitional control in multitask environments, subjects may engage in a variety of strategies to guide task selection. The current research examines whether subjects may sometimes use a top-down control strategy of selecting a task-irrelevant stimulus dimension, such as location, to guide task selection. We term this approach a stimulus set selection strategy. Using a voluntary task switching procedure, subjects voluntarily switched between categorizing letter and number stimuli that appeared in two, four, or eight possible target locations. Effects of stimulus availability, manipulated by varying the stimulus onset asynchrony between the two target stimuli, and location repetition were analysed to assess the use of a stimulus set selection strategy. Considered across position condition, Experiment 1 showed effects of both stimulus availability and location repetition on task choice suggesting that only in the 2-position condition, where selection based on location always results in a target at the selected location, subjects may have been using a stimulus set selection strategy on some trials. Experiment 2 replicated and extended these findings in a visually more cluttered environment. These results indicate that, contrary to current models of task selection in voluntary task switching, the top-down control of task selection may occur in the absence of the formation of an intention to perform a particular task.
