情绪和控制幻觉对投资者羊群行为的影响

本研究采用双因素被试间实验具体考察了特定情绪和控制幻觉对于个体投资者羊群行为的影响,结果发现存在显著的主效应和交互作用。愉悦情绪与投资者的追涨羊群行为呈正向关系,恐惧情绪与跟跌羊群行为呈正向关系;控制幻觉与投资者的追涨羊群行为呈正向关系,与跟跌羊群行为呈负向关系;高控制幻觉的投资者在愉悦情绪下倾向于乐观追涨,而低控制幻觉的投资者在恐惧情绪下倾向于悲观跟跌。     

歧视知觉对初中生的合作倾向与行为的影响

本文通过两个研究揭示歧视知觉对初中生合作倾向与行为的影响, 研究1采用问卷法对752名初中生进行为期一年的追踪, 运用潜变量交叉滞后结构方程模型分析歧视知觉与合作倾向之间的纵向预测关系; 研究2采用动态公共物品困境实验考察歧视知觉对合作行为的影响, 以及群体类型的调节作用。结果发现：(1)初中生的歧视知觉与合作倾向存在显著负相关; T1合作倾向可负向预测T2歧视知觉, T2歧视知觉可负向预测T3合作倾向; (2)在公共物品困境前三轮投资比和贡献率上, 歧视知觉和群体类型的交互效应显著; 而在后三轮仅发现歧视知觉在投资比和贡献率上的主效应, 以及群体类型在贡献率上的主效应。以上结果表明, 歧视知觉与合作倾向之间存在纵向螺旋式影响; 歧视知觉对前期合作行为的影响受到群体类型的调节, 但随着互动时间延长, 该调节作用消失。     

个体证券投资者自我效能感对赌徒谬误的影响

赌徒谬误指当某一独立随机事件发生后,人们倾向认为这一结果再次出现的概率降低。如果一连串的随机事件呈现出一定的趋势,人们倾向于认为随机事件将呈现系统性反转。证券市场中的赌徒谬误指在股票上涨（下跌）序列中做出股价将要下跌（上涨）的判断。本研究探讨股票市场特征（趋势长度及方向）及投资者的人格特征（自我效能感）对赌徒谬误的影响。以83名股票投资者为对象,采用多层线性模型进行分析,结果发现：趋势长度主效应显著,短线情境下赌徒谬误频次更高;趋势方向主效应显著,下跌情境下赌徒谬误频次更高;二者交互作用显著,在短线下跌情境下,赌徒谬误频次更高;投资者的自我效能感对股票趋势长度具有调节作用,高自我效能的投资者在短线情境下更容易出现赌徒谬误。     

信息和独立性对投资者羊群行为影响的实验研究

本研究使用实验法研究了个体投资者的羊群行为。研究发现:信息对称性和个性心理特征中的独立性对投资者的羊群行为的影响显著,它们之间存在交互作用,共同影响投资者的羊群行为倾向;信息对称性和个性心理特征中的独立性对投资者的投资绩效的影响显著,它们之间不存在交互作用。     

上级反馈对员工行为的影响

采用2×2(反馈方式、反馈对象)两因素组间实验设计,选取303名被试考察了上级反馈对员工积极整合行为倾向、冲突行为倾向和中立行为倾向的影响,以及个人主义-集体主义倾向对这种影响的调节作用。结果表明,Singelis、Triandis等人有关个人主义、集体主义的理论框架基本适合中国被试,个体的个人主义、集体主义倾向对反馈的效果起到一定的调节作用。领导的反馈方式、反馈针对的对象对员工的行为主效应都显著,上级的表扬会增加员工的中立行为倾向,针对个人的反馈会引起较强的冲突行为倾向。     

禀赋效应对产品更换决策的影响

以禀赋效应理论为研究基础, 通过两个情景实验对产品更换过程中买卖双方的决策心理进行了研究。实验1表明, 在以旧换新活动中新产品的买方对旧产品的价格有高估的倾向, 对新产品的价格有低估的倾向; 相反, 新产品的卖方对旧产品的价格有低估的倾向, 而对于新产品的价格有高估的倾向, 这说明产品更换决策中存在着双重的禀赋效应。实验2表明, 新产品的买方对旧产品的属性评价显著高于新产品的卖方, 对新产品的属性评价显著低于新产品的卖方, 说明属性评价也存在禀赋效应的特征。双重禀赋效应的存在从消费者行为的角度解释了为什么消费者会出现创新抵制行为。     

关于我国投资者从众行为的实证研究

由于广大投资者的行为决策与心理因素密切相关,因而深入分析从众行为对于投资决策的影响．对于推动我国证券市场健康发展以及促使投资者形成理性投资决策具有重要的现实意义。本研究发现：我国投资者从众行为的特征差异可以从信息权威性、关系亲密性、环境一致性、团组压力性、知识充分性、情绪稳定性、专注耐心性、信息敏感性这八个因素进行分析;投资者可分为“从众追风型”、“环境适应型”以及“独立稳定型”三类。     

投资者情绪与上市公司投资水平——迎合还是保守?

资本市场的投资者并不完全理性,会出现对股票价格的高估或低估.本研究以2003 ～ 2010年我国上市公司为对象进行研究,发现在面对非理性的投资者时,公司管理者同时存在迎合心理和保守主义倾向,且受到公司融资约束条件的影响.迎合渠道是投资者情绪影响公司投资水平的主要渠道,即使是低融资约束的公司,也表现出了显著的迎合行为,而高融资约束的公司则对投资者情绪的效应更敏感.但是,只有在低融资约束情况下,部分公司才会在投资决策中表现出保守主义倾向.     

组织危机沟通回应策略对员工情绪和行为的影响

通过实验探究危机情境下组织回应策略对员工的负性情绪和行为倾向的影响。实验一采用被试间设计。探讨公众舆论危机情境下组织回应策略(机会解释,威胁解释)对员工情绪和行为倾向的影响。实验二采用2×2的被试间实验设计,探讨管理惩戒危机情境下利益相关性(主相关,他相关)和组织回应策略类型对员工情绪和行为倾向的影响。结果发现,威胁解释下被试的负性情绪更高;机会解释下的被试发生负性网络行为可能性高于威胁解释,但现实行为倾向水平均较低;员工利益主相关情境下,被试负性行为倾向更高,危机情境类型和组织回应策略类型交互作用显著。研究表明:机会解释对抑制员工的负性情绪更有效;威胁解释对抑制员工的负性网络行为倾向更有效;员工利益主相关的危机情境会使员工的负性情绪和负性行为水平更高。     

组织公正和职位对进谏行为的影响

本实验目的在于验证组织是否公正、职位的高低对进谏行为的影响.选取158名大学生为被试,采用2×2完全随机设计,以情境故事法呈现刺激,研究了组织公正与否、职位的高低对进谏行为的影响.结果表明,组织氛围(公正/不公正)的主效应显著,职位的主效应不显著,组织氛围与职位的交互作用显著,具体表现为:低职位的在组织氛围不同情况下,进谏行为差异显著;而在组织不公正的氛围下,职位不同其进竦行为差异显著.     

Life experience and the value-free foundations of Blumer's collective behavior theory

Herbert Blumer stated throughout his long career that his ideas regarding collective behavior originated with his introduction to pragmatist philosophy under the auspices of G. H. Mead at the University of Chicago. Blumer's biography, however, presents a different picture. Firsthand experiences with mob behavior, collective outrage, and the fallout associated with Blumer's public utterances early in his career may have had significant impact on the eventual corpus of collective behavior.     

Roger T. Kelleher, behavior analyst

Roger T. Kelleher, rightly known as one of the foremost contributors to behavioral pharmacology, also made many important contributions to the experimental analysis of behavior. He participated significantly in the development of the discipline, through both his research and his editorial contributions to thisjournal. This article summarizes his contributions to the field of behavior analysis. His most significant empirical and conceptual contributions to behavior analysis came in two domains-conditioned reinforcement and the power of schedules of reinforcement. His accomplishments in these two domains still serve as principal foundations for modern research and theory.     

TEACHING CHILDREN APPROPRIATE SHOPPING BEHAVIOR THROUGH PARENT TRAINING IN THE SUPERMARKET SETTING1

The shopping behavior of three elementary school-age boys was analyzed and parent-child interactions assessed for one boy and his mother. Estimates of parent or consumer satisfaction with child shopping behavior were also obtained. The effects of a parent-mediated treatment package on child behavior were assessed using a multiple-baseline design. Treatment produced significant increases in appropriate shopping behavior in all three children and parents became increasingly satisfied with improved child behavior. Analysis of data for one mother also revealed that her manner of interacting with her child became more positive.     

In Celebration of Nature: A Dialogue With Jerome Kagan

Jerome Kagan has studied the role of biology as a major determinant of human behavior for more than three decades. The results of this research have had significant impact on the field of developmental psychology and on our understanding of temperamental factors. Dr. Kagan discusses his career and the practical implications of his research.     

Suicide in a middle-born child

A case of suicide in a 17-year-old boy is described. Extracts from an interview with his mother are used to illustrate his violent behavior, delinquency, relationships with his family and peers, efforts to seek treatment, and the clues he gave to his impending suicide. His life-style and subsequent suicidal behavior are related to his middle-born sibling position.     

Why Tyrants Go Too Far: Malignant Narcissism and Absolute Power

This article explores the puzzling behavior of tyrants who undermine themselves once in power. The realpolitik perspective and a variety of psychological frameworks are used to try to resolve this puzzle in the cases of several ancient and three contemporary tyrants. Although all the frameworks used have explanatory power, the one that most closely fits the tyrants studied here is that of the narcissist with severe superego deficiencies. An individual with such psychological characteristics may have some advantages in rising to power, and his behavior may be an effective response to some real-life factors, but once he has consolidated his position his reality-testing capacities diminish. Fantasies held in check when his power is limited are apt to become his guides to action. As a consequence, his behavior becomes more erratic, he runs into difficulties in meeting his goals, and his paranoid defenses become more exaggerated. The finale of a tyrant's career depends on the particulars of his political and social situation.     

MULTICOMPONENT INTERVENTION FOR AGITATED BEHAVIOR IN A PERSON WITH ALZHEIMER'S DISEASE

We evaluated a multicomponent intervention for agitated behavior in a man with probable Alzheimer's disease. Hypotheses about variables controlling his agitated behavior guided intervention design. Based on staff interviews, direct observations, and brief experimental probes, intervention components were chosen to increase rate of reinforcement and decrease aversive aspects of his job. Intervention reduced agitated behavior without disrupting his work rate.
