Semantic and visual relatedness of distractors impairs episodic retrieval of pictures in a divided attention paradigm

We used a divided attention (DA) paradigm to infer the representational codes needed to support episodic retrieval of pictures, by measuring susceptibility to memory interference from different distracting tasks. Participants made recognition memory decisions to semantically categorized sets of pictures while simultaneously making size judgments to a set of visually-presented distractor pictures. Recognition accuracy was worse and response times were slower under DA conditions relative to full attention (FA), regardless of semantic relatedness of distractors to targets (Experiment 1). Similarly, we found no differential memory interference under DA relative to FA when distractor pictures were either visually (but not semantically), semantically (but not visually), or unrelated to the targets (Experiment 2). In Experiment 3, memory interference was significantly larger under DA at retrieval when distractors were both semantically and visually similar to the targets. Findings suggest episodic memory for pictures requires access to either visually- or semantically-based representations for optimal performance.     

个体特征因素对师徒之间选择倾向的影响

师徒的相互选择过程是师徒关系研究中的一个重要问题。本文采用三个实验探讨了影响师徒相互选择倾向的个体特征因素。实验一和实验二探讨了徒弟选师傅时,师傅的外向性、成就动机水平、管理职务和性别一致性对徒弟选择师傅倾向的影响。实验三探讨了师傅选择徒弟时,徒弟的外向性、成就动机水平和性别一致性对师傅选择徒弟倾向的影响。实验结果表明在徒弟选择师傅时,师傅的外向性、成就动机、管理职务,是影响因素;在师傅选择徒弟时,徒弟的外向性、成就动机水平是影响因素。     

Indiscernible universals

Universals have traditionally thought to obey the identity of indiscernibles, that is, it has traditionally been thought that there can be no perfectly similar universals. But at least in the conception of universals as immanent, there is nothing that rules out there being indiscernible universals. In this paper, I shall argue that there is useful work indiscernible universals can do, and so there might be reason to postulate indiscernible universals. In particular, I shall argue that postulating indiscernible universals can allow a theory of universals to identify particulars with bundles of universals, and that postulating indiscernible universals can allow a theory of universals to develop an account of the resemblance of quantitative universals that avoids the objections that Armstrong’s account faces. Finally, I shall respond to some objections and I shall undermine the criterion of distinction between particulars and universals that says that the distinction between particulars and universals lies in that while there can be indiscernible particulars, there cannot be indiscernible universals.     

The effect of spatial frequency information and visual similarity in threat detection

In the current research, we sought to examine the role of spatial frequency on the detection of threat using a speeded visual search paradigm. Participants searched for threat-relevant (snakes or spiders) or non-threat-relevant (frogs or cockroaches) targets in an array of neutral (flowers or mushrooms) distracters, and we measured search performance with images filtered to contain different levels (high and low) of spatial frequency information. The results replicate previous work demonstrating more rapid detection of threatening versus non-threatening stimuli [e.g. LoBue, V. & DeLoache, J. S. (2008). Detecting the snake in the grass: Attention to fear-relevant stimuli by adults and young children. Psychological Science, 19, 284–289. doi:10.1111/j.1467-9280.2008.02081.x]. Most importantly, the results suggest that low spatial frequency or relatively coarse levels of visual information is sufficient for the rapid and accurate detection of threatening stimuli. Furthermore, the results also suggest that visual similarity between the stimuli used in the search tasks plays a significant role in speeded detection. The results are discussed in terms of the theoretical implications for the rapid detection of threat and methodological implications for properly accounting for similarity between the stimuli in visual search studies.

Contrasting rule-based and similarity-based category learning: The effects of mood and prior knowledge on ambiguous categorization

This study adopts a dual-system view of category learning. The findings suggest that consumers who learn a dominant feature as a verbal rule for a product category will classify a new ambiguous product according to that feature even if it more closely resembles a different product category. The findings also demonstrate that dominant features can bias categorization toward a less prototypical category in the event that the new product breaks the rule. We refer to this phenomenon as criterial inferencing. Lastly, we offer unique empirical evidence to suggest that mood influences category learning and thus attenuates the criterial inferencing bias.     

不熟悉材料伴随熟悉类别标签时儿童的归纳推理

对呈现在儿童面前的不熟悉的材料用儿童熟悉的、各不相同的类别标签命名之后,使儿童面临知觉相似和类别冲突的情形下,研究了儿童的归纳推理及其发展。研究结果显示,在此情形下,5岁儿童的归纳推理主要是基于知觉相似的,7岁儿童基于知觉相似和基于类别的归纳推理之间差异不显著,11岁儿童则主要基于类别进行归纳推理。     

相似性、相似性组合及元认知监控对问题类比推理的影响研究

以改编Holyoak等设计的“汇聚问题”为实验材料,同时自编元认知监控问卷测试被试的元认知监控水平,考察相似性的不同水平,源问题个数,两个源问题情境下源问题的组合方式以及被试的元认知监控水平对类比迁移的影响。结果表明,一个源问题呈现情境下,源、靶问题不同的相似性水平差异显著,表面相似性显著促进类比迁移;两个源问题呈现情境下,源问题的不同组合方式差异显著;无论是呈现一个源问题,还是呈现两个源问题,元认知监控差异均显著,类比迁移主要是控制性加工;源问题个数差异显著。     

婚恋关系中的相似性匹配及争议

婚恋匹配涉及身体特征、社会人口统计学特征、个性心理等方面,有相似性匹配和互补性匹配两种假说,但相似匹配的证据远多于互补。针对感知相似与实际相似的作用、相似性匹配与婚恋质量的关系、以及相似匹配的优势地位与适宜性等争议,分析了导致相似性匹配争议的原因。未来应致力于深化研究内容以建立婚恋匹配理论模型,实现测评方法的多样化、测量指标和工具的科学化,确保相似性计算和统计分析方法的严谨性,并加强婚恋匹配的本土化和跨文化研究。     

夫妻价值观相似性、沟通模式与婚姻质量的关系*

夫妻相似性和婚姻质量的关系一直是婚姻适应研究领域关注的重要课题,然而至今并没有得到一致的结论,而且两者间的作用机制也没有得到充分探讨。为此,从澳门选取132对夫妻,采用夫妻独立作答的方式,对他们的价值观,沟通模式和婚姻适应进行测查,以探讨夫妻价值观的相似性和差异,以及沟通在夫妻价值观相似性和婚姻质量两者关系间的作用。经t检验、阶层内相关和结构方差模型分析,结果发现:(1)夫妻在价值观方面存在相似性,其实夫妻的相似性明显多于随机配对的夫妻;也存在差异,其中丈夫比妻子更看重权力和成就;(2)丈夫报告的双方回避沟通明显多于妻子,但其报告的婚姻满意度和情感表达明显好于妻子;(3)研究不仅验证了以往研究结果,即夫妻越相似,其婚姻质量就越高,而且进一步发现这种关系通过沟通起作用。最后,研究得出结论,伴侣选择应是相似和互补结合的产物,而沟通是夫妻关系的基石。
