青少年脑发育的神经法学研究与应用

神经科学研究的发展推动并孕育了新兴交叉学科--神经法学, 青少年脑发育与其刑事责任能力的关系是神经法学的重要关注内容。研究发现, 青少年中期冒险行为倾向加剧可能源于其社会情感和认知控制的脑发育轨迹不同, 由皮层下组织主导的社会情感系统呈倒U形发展趋势, 在青少年中期达到峰值, 而由额叶成熟主导的认知控制系统发展呈线性增长,到成人早期才完成, 即, 皮层下组织与前额皮层的功能成熟不平衡导致了青少年的高犯罪率。这些神经科学证据已经进入美国青少年刑事案件的审判并产生实质影响, 但也有人对神经科学证据应用于法庭持有异议。相对于法律系统的需求, 青少年脑发育的神经法学需要在研究和实践方面同时努力。

Neurocomputational mechanisms of reinforcement-guided learning in humans: A review

Adapting decision making according to dynamic and probabilistic changes in action-reward contingencies is critical for survival in a competitive and resource-limited world. Much research has focused on elucidating the neural systems and computations that underlie how the brain identifies whether the consequences of actions are relatively good or bad. In contrast, less empirical research has focused on the mechanisms by which reinforcements might be used to guide decision making. Here, I review recent studies in which an attempt to bridge this gap has been made by characterizing how humans use reward information to guide and optimize decision making. Regions that have been implicated in reinforcement processing, including the striatum, orbitofrontal cortex, and anterior cingulate, also seem to mediate how reinforcements are used to adjust subsequent decision making. This research provides insights into why the brain devotes resources to evaluating reinforcements and suggests a direction for future research, from studying the mechanisms of reinforcement processing to studying the mechanisms of reinforcement learning.     

Roasting Ethics

What are the rules of the comedic roast? Initially, there might seem to be a tension between “the comedic” and “roasting” or “insult.” The comedic is concerned with the funny or mirth while insults are mean-spirited in nature, tools of injury. So how can the two be combined to produce something fun? In this article, I entertain a few views that attempt a resolution of this apparent tension. I conclude with a proposal that suggests when they are successful, roasts employ mechanisms that redirect attention from the joke's content to its formal properties; it is when those mechanisms fail that roasting becomes disagreeable.     

The Long Arm of Religion: Childhood Adversity,Religion, and Self‐perception Among Black Americans

Significant associations between childhood adversity and adult mental health have been documented in epidemiological and social science research. However, there is a dearth of research examining this relationship among black Americans, as well as into what cultural institutions and practices may help individuals in dealing with childhood adversity. This study suggests that religion may be an important resource for black Americans in the face of early‐life socioeconomic and health disadvantage. Using data from the National Survey of American Life, a nationally representative sample of both African Americans and black Caribbeans (n = 5,191), this study outlines a series of arguments linking childhood adversity, religiosity, and self‐perception among black Americans. The results suggest some support for religious involvement in moderating—or buffering—the harmful effects of childhood adversity on the self‐esteem and mastery among black Americans, specifically religious service attendance and religious coping. In addition, the results reveal that religion may also amplify the deleterious effects of childhood disadvantage on adult mental health. Study limitations are identified and several promising directions for future research are discussed.     

Perceptions of Personal Avoidability Versus Responsibility: How Do They Differ?

A great deal of recent social psychological research has focused on the attributions made by individuals who experience serious life crises. This research suggests that individuals frequently hold themselves responsible for seemingly uncontrollable events. Researchers have hypothesized about why this might occur and about which types of self-attributions might be more adaptive than others. In this article, it is argued that attributions of responsibility to the self may be less common than this previous research appears to suggest. Lay people may be making subtle distinctions between responsibility and avoidability, thus feeling they can avoid future negative outcomes without feeling responsible for what has occurred. This argument is made with illustrative results from a pilot study of female rape victims.     

Judgment and decision making: Behavioral approaches

The area of judgment and decision making has given rise to the study of many interesting phenomena, including reasoning fallacies, which are also of interest to behavior analysts. Indeed, techniques and principles of behavior analysis may be applied to study these fallacies. This article reviews research from a behavioral perspective that suggests that humans are not the information-seekers we sometimes suppose ourselves to be. Nor do we utilize information effectively when it is presented. This is shown from the results of research utilizing matching to sample and other behavioral tools (monetary reward, feedback, instructional control) to study phenomena such as the conjunction fallacy, base-rate neglect, and probability matching. Research from a behavioral perspective can complement research from other perspectives in furthering our understanding of judgment and decision making.     

女性食物选择的演化视角：基于性选择过程的理论探讨

性选择在人类心理、行为等表型的演化过程中扮演了重要角色,但其对女性食物选择的影响却相对较少被关注。性选择塑造了男女不同的择偶策略,男性择偶时对女性外在吸引力的关注使得女性更加重视身材等外在吸引力信息。而女性身材与饮食的密切联系,进一步提示性选择过程应该会对女性的食物选择产生影响。以之为基础,梳理求偶动机激活可能引发的女性食物选择的变化,以及女性生理期不同阶段在食物选择上的变异,有助于了解性选择过程对女性食物选择的影响。未来研究中,进一步从行为、激素、脑等不同层面剖析对应影响及涉及机制,对该领域的长远发展有重要意义。     

Feminists on the inalienability of human embryos

The feminist literature against the commodification of embryos in human embryo research includes an argument to the effect that embryos are "intimately connected" to persons, or morally inalienable from them. We explore why embryos might be inalienable to persons and why feminists might find this view appealing. But, ultimately, as feminists, we reject this view because it is inconsistent with full respect for women's reproductive autonomy and with a feminist conception of persons as relational, embodied beings. Overall, feminists should avoid claims about embryos' being inalienable to persons in arguments for or against the commodification of human embryos.     

Videotape as a replacement for the human observer in studies of nonhuman primate behavior

Bucknell University, Lewisburg, Pennsylvania 17837 For both field and laboratory studies of animal behavior, the availability of portable videotape recorders permits both improved techniques of observation and a means for permanent storage and rapid retrieval of observations. In some circumstances, videotape may be used to replace a human O. Evidence is presented that the behavior of at least one nonhuman primate commonly used in behavioral research, the squirrel monkey, differs when a human 0 is present from when behavior is recorded solely by videotape, even after 3 years of daily contact with human beings.     

Perceptions of Hospitalization by Children with Chronic Illnesses and Siblings

Understanding children’s perceptions of their illnesses and functioning when they are undergoing medical procedures remains an important area for research. Further research about siblings’ perceptions will also provide knowledge about how they are coping with a brother or sister’s chronic illness. The current study examined the perceptions of children with illnesses and their siblings using a play interview. Themes in the data indicated resilience in child functioning for both patients and siblings. Children with chronic illnesses could experience pain, which often related to fears and other negative feelings about hospitalization and potentially doctors or nurses, if they were administering painful procedures. Distraction and prayer were coping tools for patients. However, most patients believed their illness and recovery would be a “long journey.” Brothers and sisters of children with chronic illnesses could experience loneliness. A more common report was a strong desire to help and be a support for a brother or sister with an illness. Support from parents was critical for both patients and siblings and both typically enjoyed child life activities. A member-checking process, with a different group of children with illnesses and siblings, was used to audit themes discovered after reviewing play interviews. The audit process supported the positive and negative themes in the data. In the future, examining the impact of magical thinking on outcomes and conducting studies after the children have gained distance from medical trauma will be important. Moreover, increasing a focus on resilience as a hallmark of children’s functioning remains another area for further research.     

Social and Behavioral Researchers' Experiences With Their IRBs

This article examines the responsibilities of researchers who conduct exploratory research to provide a service to vulnerable respondents. The term “service” is used to denote the provision of a tangible benefit in relation to the research question that is apart from the altruistic research benefits. This article explores what this “service” could look like, who might be responsible for providing it, and the challenges associated with such a service. The article argues that not providing a tangible benefit to vulnerable research participants is inconsistent with the principle of social justice that undergirds much of the rationale for conducting health disparities research.     

Therapeutic strategy and psychoanalytic technique

The role of therapeutic strategy within psychoanalytic technique is described. An antistrategic bias inherent in certain aspects of the "classical" technique is explored in relation to the historical development of psychoanalysis. Clinical expertise, which includes the making of strategic or tactical choices, is relegated to the "unofficial," due in part to this negative bias impeding the study of technical differences in favor of general agreement about a theory of technique that may differ considerably from actual clinical work. A case is presented that illustrates strategic choices in the management of a severe character resistance in a supervised analysis. Some consequences of a negative bias against therapeutic strategy as it relates to psychoanalytic training is described.     

Telomeres in a Life-Span Perspective: A New "Psychobiomarker"?

ABSTRACT— In order to more fully understand associations between psychological stress and health, it is helpful for researchers to identify "psychobiomarkers," or biological measures that are regulated in part by psychological function and that predict longevity. Telomere length appears to be such a measure. Telomeres, the protective caps at the tips of chromosomes, shorten with age, and this shortening predicts disease and longevity. Leukocyte telomere length may be best viewed through a life-span approach, as it reflects in part the cumulative number of cell divisions that have occurred and the long-term biochemical environment. Recently, a critical mass of studies demonstrated that telomeres appear to shorten with chronic stress, although the mechanisms are unknown. This paper reviews what appear to be malleable determinants of rate of telomere attrition, focusing on early life chronic stressors and metabolic adversity (poor nutrition during development, and obesity). The next generation of research will benefit from experimental and longitudinal models integrating genetic variation, social environments, life experience, and health behaviors.     

Exploratory Health Disparities Research: The Need to Provide a Tangible Benefit to Vulnerable Respondents

This article examines the responsibilities of researchers who conduct exploratory research to provide a service to vulnerable respondents. The term "service" is used to denote the provision of a tangible benefit in relation to the research question that is apart from the altruistic research benefits. This article explores what this "service" could look like, who might be responsible for providing it, and the challenges associated with such a service. The article argues that not providing a tangible benefit to vulnerable research participants is inconsistent with the principle of social justice that undergirds much of the rationale for conducting health disparities research.     

Systems for multivariate monitoring of behavioral status over time

Decision-theoretic criteria are presented for optimizing the information gathered from a series of interviews over time. It is shown that the optimum interviewing strategy depends strongly on assumptions about the covariation of behavior over time. Standard interviewing strategies, including the major-problem/target-complaints approach, are optimal only under extreme assumptions about behavior. An interviewing strategy based on dynamic programming is presented that will provide optimal information return from a series of interviews under assumptions that are realistic for mental health applications. A system using this approach can tailor its interviewing strategy to adapt to differences in interview content, item importance, and individual response patterns, selecting the optimally informative questions to ask each subject at each point in time. Simulation results show that this approach achieves a 34% reduction in the false negatives obtained with the major-problem/target-complaints method, and, depending on the acceptable error rate, a reduction of 47 % or more in the questions that are needed in standard interviewing.     

Discriminative facility and its role in the perceived quality of interactional experiences

Discriminative facility refers to an individual's sensitivity to subtle cues about the psychological meaning of a situation. This research aimed at examining (a) the conceptual distinctiveness of discriminative facility, (b) the situation-appropriate aspect of this construct, and (c) the relationship between discriminative facility and interpersonal experiences. Discriminative facility was assessed by a new measure of situation-appropriate behaviors across a variety of novel stressful situations. Results from study 1 showed that discriminative facility had weak positive relationships with cognitive complexity and nonsignificant relationships with self-monitoring and social desirability, indicating that discriminative facility is a unique construct. Results from Study 2 revealed that higher levels of discriminative facility were associated with higher levels of perceived social support and a greater number of pleasant interpersonal events experienced, thus providing support for the theoretical proposition that discriminative facility is an aspect of social intelligence.     

Entrepreneurial Logics and the Evolution of Falun Gong

This article documents the shift of Falun Gong from a primarily secular healing system to a new religion centering on salvation. Emerging as a qigong organization in China in the early 1990s that provided immediate healing treatments to practitioners, Falun Gong eventually developed into a salvation-oriented religious firm. Mr. Li Hongzhi, the founder of Falun Gong, played a vital role in promoting the movement's transition. Facing the competitive qigong market, Mr. Li decided to differentiate Falun Gong from other competing qigong movements by offering a theory about salvation. He also adopted other organizational and doctrinal mechanisms that are useful in sustaining practitioners and preventing potential schisms. These strategies partly accounted for the growth of Falun Gong in the 1990s. This case study indicates that the religious economy model is helpful in understanding the evolution of Falun Gong, a new religion in contemporary China.     

Eyewitness decisions in simultaneous and sequential lineups: A dual-process signal detection theory analysis

Many eyewitness researchers have argued for the application of a sequential alternative to the traditional simultaneous lineup, given its role in decreasing false identifications of innocent suspects (sequential superiority effect). However, Ebbesen and Flowe (2002) have recently noted that sequential lineups may merely bring about a shift in response criterion, having no effect on discrimination accuracy. We explored this claim, using a method that allows signal detection theory measures to be collected from eyewitnesses. In three experiments, lineup type was factorially combined with conditions expected to influence response criterion and/or discrimination accuracy. Results were consistent with signal detection theory predictions, including that of a conservative criterion shift with the sequential presentation of lineups. In a fourth experiment, we explored the phenomenological basis for the criterion shift, using the remember-know-guess procedure. In accord with previous research, the criterion shift in sequential lineups was associated with a reduction in familiarity-based responding. It is proposed that the relative similarity between lineup members may create a context in which fluency-based processing is facilitated to a greater extent when lineup members are presented simultaneously.     

The Towers of Silence: creative and destructive issues for therapeutic teams dealing with sexual abuse

Intra-familial sexual abuse of children is a peculiarly potent area for subsequent inter-agency responses and interventions to become inappropriate, irrational, and damaging. A major component of the damaging responses by the inter-agency system is the mirroring processes which occur between that system and the family.
A case example is presented in some detail to illustrate the ways in which such mirroring processes also effect therapeutic teams dealing with such families. Some therapeutic techniques from an experiential base are described. It is argued that productive therapeutic work can only occur if the mirroring processes within the inter-agency system, and the therapeutic team system, are considered systemically.
