关于思维和语言起源问题的对话(一)

一天,余先生与张、李两位研究生谈论思维和语言的起源问题,下面是他们的对话。张:余先生,现今的科学发展使人与动物的界限似乎比以前更加模糊了。人类有思维,许多动物也有思维的分析、判断能力;人类有语言,一些西方科学家断言野生黑猩猩中间也存在着语言学家所定义的真正的语言。而教猩猩、黑猩猩和大猩猩幼仔说话的科学实验还证明,这些动物能够掌握人类的手势语或其他有形语言符号,可学到350—650个单词,并能与人类交谈,其智力可达到人类学龄前儿童的水平。这些情况是不是说明,在思维和语言的     

特质正念与控制点调节日常生活中知觉压力对消极情绪的影响

考察日常生活中知觉压力对消极情绪的动态影响,检验特质正念的调节作用,并进一步探索正念的调节作用是否在不同控制点的个体中存在差异。共有95名在校大学生完成正念注意觉知量表（MAAS）,罗特控制点量表（LOCS）,并通过动态评估的方式,完成每天2次,持续14天的在日常生活情境中针对知觉压力和消极情绪的密集型追踪测量。多层线性模型结果表明：（1）在个体内水平,个体某一时刻的知觉压力可以显著预测个体下一时刻的消极情绪;（2）个体的正念水平越高,日常生活中知觉压力对消极情绪的预测力越低;（3）个体越倾向于内控,日常生活中知觉压力对消极情绪的预测力越低;（4）个体越倾向于外控,正念对日常生活中知觉压力影响消极情绪的调节作用越强。本研究验证了正念对日常生活中压力反应的保护作用,并提示外控者在面临压力时更有可能从正念中获益。

不同心理一致感个体压力情境下的情绪特点研究

以46名大学生为被试,利用“九洞仪”创设实验室压力情境,考察不同心理一致感个体压力情境下的情绪反应及恢复特点。结果表明：（1）压力情境下,高、低心理一致感个体的情绪反应存在显著性差异。高心理一致感个体出现较多的积极情绪,低心理一致感个体则以消极情绪体验为主。（2）低心理一致感压力情境诱发出的消极情绪显著多于积极情绪,消极情绪的诱发量较大。（3）压力任务后,高心理一致感个体在情绪恢复量上显著多于低心理一致感个体,心理健康的自我康复力较大。（4）压力任务前后,低心理一致感个体的消极情绪诱发量显著高于恢复量,在消极情绪变化上表现出“诱发多,恢复少”的特点。     

中国背景下情绪智力与心理健康关系的元分析

本研究使用元分析的方法探讨了情绪智力与心理健康的关系（包括心理健康症状学指标、感知到的压力、应对方式、社会适应及主观幸福感）,共纳入104篇文献,151个独立样本和75754名被试。结果发现,个体情绪智力与积极应对、社会适应以及主观幸福感呈现显著正相关,与心理健康症状学指标、感知到的压力以及消极应对呈现显著负相关。此外,情绪智力与心理健康的关系受到出版年代、被试年龄、情绪智力理论模型和测量工具的调节作用。结论表明,情绪智力与积极心理健康变量的联系强于与消极心理健康变量的联系,且存在较长时期的稳定性。     

移情反应的研究 ——基于个体倾向与情境的双重视角

摘 要：本研究基于个体倾向和情境的双重视角,将静态与动态相结合,探讨不同移情能力的个体在真实性不同情境中的移情反应。结果发现： （1）移情能力高、低分组得分存在显著性差异;（2）情境真实性高、低两种情境之间差异不显著;（3）在某些具体的移情反应上,移情能力与情境的交互作用显著;（4）性别差异不显著。属个体倾向范畴的移情能力对移情反应具有显著影响,情境对移情反应的影响与移情能力有关,移情能力高的个体对情境的变化更为敏感。     

泛文化的自尊——基于中国大学生的研究证据

过去一直认为,自尊是人类普遍的需要,是泛文化的。但是,过去十多年来,这一观点受到严重挑战。其主要理由是许多跨文化的研究显示集体主义文化下个体的自尊显著低于西方,少有自我促进的迹象。但是,几乎所有这样的证据都是来自自陈式测量。由于自陈式测量难以避免自我展现（Self-presentation）或社会期许（Social Desirability）的影响,并且严重依赖于个体的自我报告,本研究采用新的能够防止社会期许的影响并能触及无意识的内隐测量——阈下评价性启动（Subliminal Evaluative Priming）程序,对中国大学生的自尊进行了研究。结果发现中国大学生对自我持有显著的积极、肯定的评价,中国人存在内隐自尊。这表明,集体主义文化下的个体的自尊需要是存在的,只是以内隐的方式表现或在自我展现的影响最小化后表现出来。这一发现和自尊的泛文化论是一致的     

决策信心校准水平对元认知监控作用的影响

决策信心是个体对自身决策正确性的主观评价,是对决策过程的元认知体验。决策信心校准指决策信心水平与实际的决策正确率之间的匹配程度,其指标有信心水平和决策正确率的相关系数及Type II信号检测论中的ROC曲线下面积（Aroc）等。已有研究发现进行决策信心评估能够增强对当前或后续决策的元认知监控作用,但目前尚不清楚这种效应是否依赖于个体的决策信心校准水平。本研究通过设置知觉决策后是否进行决策信心评估（有信心评估与无信心评估）两种条件,考察个体决策信心的校准水平（Aroc）对元认知监控作用的影响。结果显示：1）与无信心评估条件相比,有信心评估的决策反应时显著增长,决策正确率显著提高（p<0.005）;2）Aroc与有、无信心评估条件下决策正确率的增加值显著正相关（r=0.25,p=0.034）,且高Aroc组的决策正确率增加值显著高于低Aroc组（p<0.05）。结果表明,在知觉决策过程中加入决策信心评估具有增强元认知监控作用的效应,体现为决策时间的增长和决策正确率的提高。并且,这种效应的大小依赖于个体的决策信心校准水平,校准水平越高元认知监控作用越好。

被笑恐惧、被笑愉悦和笑他愉悦是三种不同的个体差异。被笑恐惧指个体在害怕被嘲笑而产生的恐惧上的差异,被笑愉悦指个体由于被别人嘲笑而产生的愉悦上的差异,笑他愉悦指个体因嘲笑他人而产生的愉悦上的差异。本研究采用问卷法以“大五”人格问卷（简式中国版）、PhoPhikat（修订中文版）为测量工具对武汉市4所高校的200名大学生进行调查以考察大学生与笑有关的三种个体差异与其与“大五”人格特征的关系。差异分析表明（1）被笑恐惧,被笑愉悦不存在显著的性别差异,笑他愉悦存在显著的性别差异（2）被笑恐惧与“大五”人格中神经质性存在显著正相关,与外倾性,友善性,严谨性存在显著负相关（3）笑他愉悦与“大五”人格中神经质性和友善性存在显著正相关。     

Tracking the displacement of objects: a series of tasks with great apes (Pan troglodytes, Pan paniscus, Gorilla gorilla, and Pongo pygmaeus) and young children (Homo sapiens)

The authors administered a series of object displacement tasks to 24 great apes and 24 30-month-old children (Homo sapiens). Objects were placed under 1 or 2 of 3 cups by visible or invisible displacements. The series included 6 tasks: delayed response, inhibition test, A not B, rotations, transpositions, and object permanence. Apes and children solved most tasks performing at comparable levels except in the transposition task, in which apes performed better than children. Ape species performed at comparable levels in all tasks except in single transpositions, in which chimpanzees (Pan troglodytes) and bonobos (Pan paniscus) performed better than gorillas (Gorilla gorilla) and orangutans (Pongo pygmeaus). All species found nonadjacent trials and rotations especially difficult. The number of elements that changed locations, the type of displacement, and having to inhibit predominant reaching responses were factors that negatively affected the subjects' performance.     

Event memory and misinformation effects in a gorilla (<Emphasis Type="Italic">Gorilla gorilla gorilla</Emphasis>)

Event memory and misinformation effects were examined in an adult male gorilla ( Gorilla gorilla gorilla). The gorilla witnessed a series of unique events, involving a familiar person engaging in a novel behavior (experiment 1), a novel person engaging in a novel behavior (experiment 2), or the presentation of a novel object (experiment 3). Following a 5- to 10-min retention interval, a tester gave the gorilla three photographs mounted on wooden cards: a photograph depicting the correct person or object and two distractor photographs drawn from the same class. The gorilla responded by returning a photograph. If correct, he was reinforced with food. Across three experiments, the gorilla performed significantly above chance at recognizing the target photograph. In experiment 4, the gorilla showed at-chance performance when the event was followed by misinformation (a class-consistent, but incorrect photograph), but significantly above-chance performance when no misinformation occurred (either correct photograph or no photograph). Although the familiarity can account for these data, they are also consistent with an episodic-memory interpretation.     

Biology Precedes, Culture Transcends: An Evolutionist's View of Human Nature

I will, first, outline what we currently know about the last 4 million years of human evolutionary history, from bipedal but small-brained Australopithecus to modern Homo sapiens, our species, through the prolific toolmaker Homo habilis and the continent wanderer Homo erectus. I shall then identify anatomical traits that distinguish us from other animals and point out our two kinds of heredity, the biological and the cultural.
Biological inheritance is based on the transmission of genetic information, in humans very much the same as in other sexually reproducing organisms. But cultural inheritance is distinctively human, based on transmission of information by a teaching and learning process that is in principle independent of biological parentage. Cultural inheritance makes possible the cumulative transmission of experience from generation to generation. Cultural heredity is a swifter and more effective (because it can be designed) mode of adaptation to the environment than the biological mode. The advent of cultural heredity ushered in cultural evolution, which transcends biological evolution.
I will, finally, explore ethical behavior as a model case of a distinctive human trait, and seek to ascertain the causal connections between human ethics and human biology. My conclusions are that (1) moral reasoning—that is, the proclivity to make ethical judgments by evaluating actions as either good or evil—is rooted in our biological nature; it is a necessary outcome of our exalted intelligence, but (2) the moral codes that guide our decisions as to which actions are good and which ones are evil are products of culture, including social and religious traditions. This second conclusion contradicts those evolutionists and sociobiologists who claim that the morally good is simply that which is promoted by the process of biological evolution.     

The clenching-grinding spectrum and fear circuitry disorders: clinical insights from the neuroscience/paleoanthropology interface

This review discusses the clenching-grinding spectrum from the neuropsychiatric/neuroevolutionary perspective. In neuropsychiatry, signs of jaw clenching may be a useful objective marker for detecting or substantiating a self-report of current subjective emotional distress. Similarly, accelerated tooth wear may be an objective clinical sign for detecting, or substantiating, long-lasting anxiety. Clenching-grinding behaviors affect at least 8 percent of the population. We argue that during the early paleolithic environment of evolutionary adaptedness, jaw clenching was an adaptive trait because it rapidly strengthened the masseter and temporalis muscles, enabling a stronger, deeper and therefore more lethal bite in expectation of conflict (warfare) with conspecifics. Similarly, sharper incisors produced by teeth grinding may have served as weaponry during early human combat. We posit that alleles predisposing to fear-induced clenching-grinding were evolutionarily conserved in the human clade (lineage) since they remained adaptive for anatomically and mitochondrially modern humans (Homo sapiens) well into the mid-paleolithic. Clenching-grinding, sleep bruxism, myofacial pain, craniomaxillofacial musculoskeletal pain, temporomandibular disorders, oro-facial pain, and the fibromyalgia/chronic fatigue spectrum disorders are linked. A 2003 Cochrane meta-analysis concluded that dental procedures for the above spectrum disorders are not evidence based. There is a need for early detection of clenching-grinding in anxiety disorder clinics and for research into science-based interventions. Finally, research needs to examine the possible utility of incorporating physical signs into Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition posttraumatic stress disorder diagnostic criteria. One of the diagnostic criterion that may need to undergo a revision in Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition is Criterion D (persistent fear-circuitry activation not present before the trauma). Grinding-induced incisor wear, and clenching-induced palpable masseter tenderness may be examples of such objective physical signs of persistent fear-circuitry activation (posttraumatic stress disorder Criterion D).     

Behavioral ethics for Homo economicus,Homo heuristicus,and Homo duplex

In this article we explore how assumptions about human nature may influence the ways one might try to promote ethical behavior in organizations. We summarize two common views of human nature in organizational research—Homo economicus and Homo heuristicus. We then extend these views by putting forward a third view of human nature initially proposed by Emile Durkheim—Homo duplex—which describes human beings as moving back and forth between a lower (individual) and higher (collective) level. We suggest that the Homo duplex view is uniquely equipped to account for variables of interest to organizational scholars because of its attention to a fundamental tension: People in organizations can be both selfish and groupish, and the balance between those tendencies influences the ethical profile of the organization in complex ways. We end with a discussion of the theoretical implications of the Homo duplex view for behavioral ethics researchers.     

EVOLUTION OF RELIGIOUS CAPACITY IN THE GENUS HOMO: COGNITIVE TIME SEQUENCE

Intrigued by the possible paths that the evolution of religious capacity may have taken, the authors identify a series of six major building blocks that form a foundation for religious capacity in genus Homo. Homo neanderthalensis and Homo sapiens idaltu are examined for early signs of religious capacity. Then, after an exploration of human plasticity and why it is so important, the analysis leads to a final building block that characterizes only Homo sapiens sapiens, beginning 200,000–400,000 years ago, when all the other cognitive and neurological underpinnings gradually came together. Because the timing of cognitive evolution has become an issue, the authors identify the time periods for these building blocks based on findings from modern cognitive science, neuroscience, genomic science, the new cognitive archaeology, and traditional stones‐and‐bones archaeology. The result is a logical, and even a likely story 55–65 million years long, which leads to the evolution of religious capacity in modern human beings.     

Presence,Content, and Characteristics of Memories of Individuals with Dental Phobia

Knowledge about memories of distressing events underlying fears and specific phobias is limited. This study assessed (1) the presence, content, and characteristics of memories of events that initiated or exacerbated dental anxiety levels; and (2) the relationship between dental trait anxiety and some key features of these memories. This study used a semi‐structured interview and included dental phobics (n = 42), subthreshold dental phobics (n = 41), and normal controls (n = 70). Dental phobics were more likely to report a memory underlying their anxiety than the normal controls. Moreover, dental phobics' memories were reported as more vivid, disturbing, and more intensely relived than the memories of the normal controls. Greater severity of dental trait anxiety was significantly associated with greater disturbance of patients' memories. The results suggest that memories of distressing events play a significant role in the development of dental phobia and that their characteristics are associated with severity of dental trait anxiety.

Dental phobias and anxieties: evidence for conditioning processes in the acquisition and modulation of a learned fear

The present study investigated some of the factors which differentiate individuals with dental anxieties and phobias from those without such fears. In particular, two questions were addressed: (i) What differentiates subjects who have never been anxious about dental treatment from subjects who at some time have been anxious? and (ii) What factors lead to subjects changing their attitudes either from anxious to relaxed or from relaxed to anxious? The results suggest that the factors which influence the acquisition and modulation of dental anxieties are consistent with the associative and representational processes portrayed in contemporary models of human conditioning. Subjects who reported never having had anxieties about dental treatment were less likely to have had a painful dental treatment than subjects who did report an anxiety. Subjects who did report a painful dental experience but did not acquire anxiety reported a history of dental treatment favourable to the operation of latent inhibition. Subjects who reported that they were good at enduring pain were more likely to report a longer interval between their very first dental treatment and their first painful dental treatment. Under some conditions in which latent inhibition should have precluded the acquisition of a dental fear, an anxiety appeared to be acquired because a very painful experience had attenuated the latent inhibition process. Subjects whose dental anxiety did not remit reported significantly more painful and traumatic dental experiences than subjects whose anxiety did remit.     

Hominid evolution, supralaryngeal vocal tract physiology, and the fossil evidence for reconstructions.

The functional, physiologic aspects of the human supralaryngeal vocal tract, which follow from the equal length of the oral and pharyngeal cavities and their right angle orientation are discussed. Sounds like the vowels [i] and [u], which only the human supralaryngeal vocal tract can produce in a Quantal mode, provide a selective advantage for vocal communication and the evolution of the human vocal tract and matched neural property detectors. The dissimilarity between Neanderthal skulls and specimens of anatomically modern Homo sapiens and other fossil skulls is discussed in relation to the reconstruction of the Neanderthal supralaryngeal vocal tract. The absence of some of the innate neural property detectors that play a part in the perception of human speech can be inferred in Neanderthal hominids from the reconstruction of their supralaryngeal vocal tract.     

Natural concepts in a juvenile gorilla (gorilla gorilla gorilla) at three levels of abstraction

The extent to which nonhumans are able to form conceptual versus perceptual discriminations remains a matter of debate. Among the great apes, only chimpanzees have been tested for conceptual understanding, defined as the ability to form discriminations not based solely on simple perceptual features of stimuli, and to transfer this learning to novel stimuli. In the present investigation, a young captive female gorilla was trained at three levels of abstraction (concrete, intermediate, and abstract) involving sets of photographs representing natural categories (e.g., orangutans vs. humans, primates vs. nonprimate animals, animals vs. foods). Within each level of abstraction, when the gorilla had learned to discriminate positive from negative exemplars in one set of photographs, a novel set was introduced. Transfer was defined in terms of high accuracy during the first two sessions with the new stimuli. The gorilla acquired discriminations at all three levels of abstraction but showed unambiguous transfer only with the concrete and abstract stimulus sets. Detailed analyses of response patterns revealed little evidence of control by simple stimulus features. Acquisition and transfer involving abstract stimulus sets suggest a conceptual basis for gorilla categorization. The gorilla's relatively poor performance with intermediate-level discriminations parallels findings with pigeons, and suggests a need to reconsider the role of perceptual information in discriminations thought to indicate conceptual behavior in nonhumans.
