Minimal Requirements for the Emergence of Learned Signaling

The emergence of signaling systems has been observed in numerous experimental and real‐world contexts, but there is no consensus on which (if any) shared mechanisms underlie such phenomena. A number of explanatory mechanisms have been proposed within several disciplines, all of which have been instantiated as credible working models. However, they are usually framed as being mutually incompatible. Using an exemplar‐based framework, we replicate these models in a minimal configuration which allows us to directly compare them. This reveals that the development of optimal signaling is driven by similar mechanisms in each model, which leads us to propose three requirements for the emergence of conventional signaling. These are the creation and transmission of referential information, a systemic bias against ambiguity, and finally some form of information loss. Considering this, we then discuss some implications for theoretical and experimental approaches to the emergence of learned communication.     

Community‐Based Learning and Critical Community Psychology Practice: Conducive and Corrosive Aspects

Community‐based learning (CBL) has been more recently introduced into some psychology programmes in the UK than in the USA, where it has existed for a number of decades in the form of ‘service learning’. CBL holds promise as a means of promoting and developing critical community psychology practice, but there are risks involved in its acritical adoption in the psychology curriculum. If associated power dynamics are not considered, CBL has the capacity to serve neoliberal interests and perpetuate, rather than challenge, oppressive social relations. This article examines ways in which CBL can be both conducive and corrosive to critical community psychology practice. Drawing on interdisciplinary literature, it explores ways in which students participating in CBL can be vulnerable to exploitation—both as victims and perpetrators—through collusion and cultural voyeurism. Consideration is given to ways of resisting institutional and other pressures to comply uncritically with the demands of the ‘employability agenda’. These include the importance of facilitated reflective processes in associated modules, to consider aspects of the interactions of people and systems. The article concludes that whilst CBL is inherently risky and involves discomfort for students, this enables development of a more informed consciousness where truly participatory work evolves towards greater social justice.

权变视角下的情绪劳动:调节变量及其作用机制

调节变量是近年来情绪劳动研究关注的重点问题之一。实证研究显示,反映员工个体特征、工作情境特征的多组变量以及文化情境对情绪劳动效应具有显著的调节作用。权变视角下的情绪劳动研究发现:(1)展现规则在组织、行业、文化三个不同水平影响个体在工作场所的情绪表达;(2)表层扮演潜在的消极效应可以借助个体内在的保护机制或通过组织管理干预被削弱、消除,甚至是转化为积极的力量;(3)深层扮演的积极效应具有较高的跨人群、跨情境稳定性;(4)文化情境对情绪劳动作用过程具有重要的约束作用。在一定条件下,情绪劳动要求、情绪劳动行为都可以成为有益于员工的组织生活要素。     

特质应对与展现规则对情绪劳动的影响

采用2×3组间设计, 检测特质应对(积极与消极)与展现规则(积极、消极、无规则)对情绪劳动的影响。结果表明, 积极应对引起更多深层动作; 积极规则下出现较少表层扮演(与消极应对比)。积极和消极规则都引起较多深层和表层动作。积极应对在积极规则下表层扮演较少(与消极规则比); 消极应对在积极规则下表层扮演较多(与消极规则比)。研究提示, 特质情绪性可能是调节展现规则与情绪劳动关系的重要原因。     

The Problem of Integrating Behavioral Health in the Medical Home and the Questions It Leads to

Psychology and other behavioral health professions have amassed a broad empirical and clinical literature suggesting many medical presentations are best responded to with the addition of evidence based behavioral interventions. Despite this, psychology has not achieved a regular presence as part of medical practice. We suggest specific reasons for the current state of affairs including clinical, operational, societal labels, financial and training dimensions. Medical, psychological, administrative, and financial perspectives are reviewed. If the goals of health care system reform are to be reached then we must identify and challenge the current limitations of health care. This paper will identify the elements that need to be changed in order for psychology to be integrated into medicine rather than excluded from its policy, planning and operations.     

谜语问题解决中线索的作用

汉语谜语在性质上属于顿悟问题,当谜语的谜底为汉语成语时,这样的谜语问题称为成语谜语问题。本研究探讨线索在成语谜语问题解决中的作用特点与方式。三个实验以汉语成语谜语问题为实验材料,采用了语义线索与规则线索,操纵了线索的有效性（有效线索占75％,无效线索占25％）,以及线索呈现的时间长短（长时间即阈限上呈现线索（实验1）,短时间（20ms）即阈限下呈现线索（实验2与实验3））两个因素。实验1与实验2的任务是要求被试写出成语谜语问题的答案（谜底）,实验3则要求被试从6个备择答案中选择出正确的答案。被试为武汉某大学的206名低年级本科生。实验结果表明,（1）无论是阈限上还是阈限下呈现规则线索,有效规则线索对成语谜语问题的解决具有促进作用;（2）有效语义线索对谜语问题的解决具有促进作用,而且,阈限上有效语义线索对谜语问题解决的促进作用更大;（3）阈限上呈现两类无效线索时,它们对成语谜语问题的解决都具有干扰作用;但是,阈限下呈现两类无效线索时,它们对成语谜语问题的解决没有干扰作用。     

论中医的辨证论治与肿瘤的分子靶向治疗

辨证论治是中医认识和治疗疾病的基本原则,“同病异治”和“异病同治”是辨证论治的精神实质。恶性肿瘤的分子靶向治疗在很多方面都贯彻了“辨证论治”观念,将所辨的证候落实到受体、基因和各种调控系统上。尽管两者理论基础完全不同,但都强调以患者为中心的综合治疗和个体化治疗理念,对建立正确的临床思维非常重要。     

下咽癌治疗的临床决策

EQUIVALENCE CLASS FORMATION: A METHOD FOR TEACHING STATISTICAL INTERACTIONS

Many students struggle with statistical concepts such as interaction. In an experimental group, participants took a paper‐and‐pencil test and then were given training to establish equivalent classes containing four different statistical interactions. All participants formed the equivalence classes and showed maintenance when probes contained novel negative exemplars. Thereafter, participants took a second paper‐and‐pencil test. Participants in the control group received two versions of the paper‐and‐pencil test without equivalence‐based instruction. All participants in the experimental group showed increased paper‐and‐pencil test scores after forming the interaction‐indicative equivalence classes. Class‐indicative responding also generalized to novel exemplars and the novel question format used in the paper‐and‐pencil test. Test scores did not change with repetition for control group participants. Implications for behavioral diagnostics and teaching technology are discussed.     

What’s the 411? Assessing the Feasibility of Providing African American Adolescents with HIV/AIDS Prevention Education in a Faith-Based Setting

This study examines African American faith based leaders’ attitudes and beliefs about providing HIV prevention education and services to adolescents. Using a convenience sample, we identified priority adolescent health issues, attitudes about abstinence messages, and willingness to provide and participate in HIV prevention. Leaders identified drugs, gangs, alcohol, sex, and pregnancy as priority health issues affecting youth in their institutions. Leaders’ strongly preferred to emphasize abstinence messages. Although leaders were willing to provide youth with health education, they were not willing to discuss specific behaviors associated with HIV transmission. African American churches provide a venue to reach African American youth; however, there are limitations to relying on faith-based HIV prevention services. HIV prevention education should continue to be supplemented via parents, schools, and public health agencies.
