发音人和语境变异与声调知觉

本文用Garner快速分类法研究了发音人规范化和语境补偿过程与声调知觉的关系。得到的主要结果是:(1)发音人变化对声调识别产生了显著的Gar-ner干扰;声调变化对男女声判别产生了同样的十扰。(2)语境变化对声调识别也产生了显著的Garner干扰。按照Garner方法的假设,这说明发音人规范化和语境变异补偿与声调识别之问是相互联系和相互影响的。(3)虽然发音人和语境同时变化引起的声调识别反应时延长约等于它们单独变化时反应时延长量之和,但正确率下降远大于单独变化时下降量之和。说明发音人和语境变异对声调识别的干扰不是独立的,它们之间存在相互作用。这种作用增加了声调识别的难度。     

When distorted logos are recognized as original? The role of the DRM procedure in detection of immediate and delayed consumers’ errors

IntroductionTo deal effectively with the market, one must create a distinct logo from competing logos. However, it is not uncommon that similarities between logos of various companies are enough to mislead consumers. This paper shows how the DRM paradigm as well as prototype theories can be used to investigate correct and erroneous recognitions of distorted familiar and unfamiliar logos in short- and long-term memory.MethodThe modified hybrid DRM procedure was adopted to test brand images that were distorted but perceptually similar. Participants performed the experimental task in which short- and long-term memory for logos were tested.ResultsThe results demonstrated no difference in memory performance between familiar and unfamiliar logos after a short delay. However, a discrepancy between recognizing both types of logos arose in long term memroy toward more errors for familiar images.ConclusionsThe results confirm that the DRM procedure can be successfully used by marketers as a potential tool in either detecting unfair competition or launching new brands.     

Anticipation of ball location in low and high-skill performers: a developmental perspective

Objectives: To study how visual anticipatory capabilities develop in high and low-skill tennis players and the role of years of practice (i.e. experience). It was expected that with accumulated experience differences will increase with skill-level, in particular under conditions of fast visual exposure which results in minimal environmental information exposure.Method: Eighty tennis players divided into 4 age categories and 2 skill levels (high and low) were selected according to 4 criterion which ensured appropriate representation of skill-level and experience in tennis. Age categories were 8–11, 11–14, 14–18, and >18. Years of experience in the game were 2.12, 4.17, 6.5, and 12.4 years respectively. Players observed filmed segments of tennis strokes on a monitor, which varied in temporal occlusion conditions from −480 ms prior to ball-racquet contact to 320 ms after contact. After each exposure they were asked to indicate the final ball location. The radial, lateral, and depth distances were averaged for age and skill level.Design: A temporal occlusion paradigm was used in this study. The film was prepared with a camera positioned in the receiver's court. Eight strokes which best represent the game of tennis were chosen. Forty-eight segments were viewed and errors were calculated for each exposure.Result: High-skill tennis players gained more from practice and experience in developing visual anticipatory skills, but their perceptual advantage was not consistent across all stroke conditions, being at its greatest number in conditions of maximal temporal constraints.Conclusions: Differences in visual anticipatory capabilities exist between different skill levels at the outset of their development. These differences increase with experience, mainly after 6–7 years. Greater knowledge base does not always guarantee a superior anticipation of upcoming events and choosing the best decision.     

It's not just what you say,it's how you say it too. Adolescents' hostile attribution of intent and emotional responses to social comments

A highly prevalent and relevant situation in which adolescents have to interpret the intentions of others is when they interact with peers. We therefore successfully introduced a new paradigm to measure hostile attribution bias (HAB) and emotional responses to such social interactions and examined how it related to youth's aggressiveness. We presented 881 adolescents (M_age = 14.35 years; SD = 1.23; 48.1% male) with audio fragments of age-mates expressing social comments that varied in content (e.g., what the person says) and tone of voice (e.g., how the person says it). Participants' peers also reported on their aggressiveness. In general, added negativity of content and tone was driving the youth's intent attribution and emotional responses to the comments. In line with the Social Information Processing model, we found more hostile attribution of intent and more negative emotional responses of aggressive youth to ambiguous stimuli. Aggression was also related to more hostile intent attributions when both content and tone were negative. Unlike most studies on HAB, the aggression effects in the current study emerged for girls, but not boys. Implications of these results and future use of the experimental paradigm are discussed.     

时距知觉的动物研究范式及相关神经机制

在探索时距知觉的脑机制的过程中, 相对于人类被试相关研究, 动物研究可以提供较多的药理学、分子生物学、单个神经元电生理学以及光遗传等方面的研究证据。目前较为常用的时距知觉动物研究范式包括时间二分法、峰值间隔法以及低比率差别强化法等。根据不同的研究需求, 动物研究的范式常会进行调整。对时距知觉的动物研究的探讨将基于两方面展开：(1) 常用的时距知觉动物研究范式的介绍及比较; (2) 基于动物研究范式的时距知觉神经机制研究进展, 旨在为深入探索时间知觉的心理学相关研究提供参考。     

Integrating experiential-phenomenological methods and neuroscience to study neural mechanisms of pain and consciousness

Understanding the nature of pain at least partly depends on recognizing its inherent first person epistemology and on using a first person experiential and third person experimental approach to study it. This approach may help to understand some of the neural mechanisms of pain and consciousness by integrating experiential-phenomenological methods with those of neuroscience. Examples that approximate this strategy include studies of second pain summation and its relationship to neural activities and brain imaging-psychophysical studies wherein sensory and affective qualities of pain are correlated with cerebral cortical activity. The experiential paradigm of offers the possibility of improved designs and methods for investigating neural mechanisms underlying pain and consciousness.     

Patients with generalized social phobia direct their attention away from faces

The experiment tested whether patients with social phobia direct their attention to or away from faces with a range of emotional expressions. A modified dot probe paradigm (J. Abnorm. Psychol. 95 (1986) 15) measured whether participants attended more to faces or to household objects. Twenty patients with social phobia were faster in identifying the probe when it occurred in the location of the household objects, regardless of whether the facial expressions were positive, neutral, or negative. In contrast, controls did not exhibit an attentional preference. The results are in line with recent theories of social phobia that emphasize the role of reduced processing of external social cues in maintaining social anxiety.     

不同深度平面与表面的视知觉完形加工

以往有关视觉完形加工的研究主要探索同一深度平面内的相似纹理表面或相关轮廓特性等对完形加工的影响。该研究采用汉字碎块,考察了双眼视差、颜色以及遮挡等线索在视觉完形中的作用。发现结果如下：视差与颜色等线索阻碍了视觉完形加工;遮挡线索加速了整体的视觉完形形成;在高级认知加工参与下,遮挡线索有效抑制了视差、颜色等线索的分离作用。通过对知觉填补机制及其理论的讨论,可以认为,该研究结果为不同深度平面间的视知觉完形加工提供了实验支持。     

Gating范式：探讨听觉词汇加工的途径

传统的反应时任务只能为听觉词汇加工提供定量数据,而不能提供定性信息,Gating范式的优势在于可以提供以上两种信息,使研究者能够全面、细致地了解听觉词汇加工的即时过程。而且它的适用群体广泛,可被用于研究不同年龄段的发展。文章较详细地介绍了Gating范式的基本特点及其在汉语研究中的应用,期待它被更多的研究者所认识和使用。     

Aviation with fraternal twin wings over the Asian context: Using nomothetic epistemic and narrative design paradigms in social psychology

The present study proposes the future trends of Asian social psychology by taking into account its possible contribution to broad cultural and historical contexts of Asia. First, I locate social psychology in a two (nomothetic vs narrative) by two (epistemic vs design) paradigm of sciences. Second, I propose that different research perspectives in social psychology (i.e. so-called mainstream and narrative-design social psychology) may be considered as fraternal twins of the same mother, classic social psychology, and describe where each of the twins is heading. Third, I introduce two modes of research activities, Mode I and Mode II, based on previous research, and examine each twin in both modes of research. Finally, I focus on the broad context of Asia and propose that we should expand two wings, especially, the second wing over the context of the region.
