Missed losses loom larger than missed gains: Electrodermal reactivity to decision choices and outcomes in a gambling task

Loss aversion is a defining characteristic of prospect theory, whereby responses are stronger to losses than to equivalently sized gains (Kahneman & Tversky Econometrica, 47, 263–291, 1979). By monitoring electrodermal activity (EDA) during a gambling task, in this study we examined physiological activity during risky decisions, as well as to both obtained (e.g., gains and losses) and counterfactual (e.g., narrowly missed gains and losses) outcomes. During the bet selection phase, EDA increased linearly with bet size, highlighting the role of somatic signals in decision-making under uncertainty in a task without any learning requirement. Outcome-related EDA scaled with the magnitudes of monetary wins and losses, and losses had a stronger impact on EDA than did equivalently sized wins. Narrowly missed wins (i.e., near-wins) and narrowly missed losses (i.e., near-losses) also evoked EDA responses, and the change of EDA as a function of the size of the missed outcome was modestly greater for near-losses than for near-wins, suggesting that near-losses have more impact on subjective value than do near-wins. Across individuals, the slope for choice-related EDA (as a function of bet size) correlated with the slope for outcome-related EDA as a function of both the obtained and counterfactual outcome magnitudes, and these correlations were stronger for loss and near-loss conditions than for win and near-win conditions. Taken together, these asymmetrical EDA patterns to objective wins and losses, as well as to near-wins and near-losses, provide a psychophysiological instantiation of the value function curve in prospect theory, which is steeper in the negative than in the positive domain.     

Moving along to things left undone

This paper expands on three areas of clinical theory that are introduced and discussed in the lead paper and the others in this symposium. The first issue addressed is the concept of the real relationship as used in the moment of meeting model of psychotherapeutic change. Particular focus has been placed on the past, the present, and the hierarchy of goals in the treatment relationship. Second, the paper explores the concept of implicit relational knowledge with attention to the concepts of transference, countertransference, interpretation, and insight in the change process. Finally, the paper attends to the nature of the “now moment” in the moment of meeting model. Specifically explicated are ways this concept relates to changes in brain organization and also ways the moment of meeting model relates to other psychotherapy models, such as the relational schools and self-psychology. © 1998 Michigan Association for Infant Mental Health     

Dyadically expanded states of consciousness and the process of therapeutic change

This paper addresses an intersubjective issue that arises out of our model of therapeutic change: Why do humans so strongly seek states of emotional connectedness and intersubjectivity and why does the failure to achieve connectedness have such a damaging effect on the mental health of the infant? A hypothesis is offered—the Dyadic Expansion of Consciousness Hypothesis—as an attempt to explain these phenomena. This hypothesis is based on the Mutual Regulation Model (MRM) of infant–adult interaction. The MRM describes the microregulatory social-emotional process of communication that generates (or fails to generate) dyadic intersubjective states of shared consciousness. In particular, the Dyadic Consciousness hypothesis argues that each individual, in one case the infant and mother or in another the patient and the therapist, is a self-organizing system that creates his or her own states of consciousness (states of brain organization), which can be expanded into more coherent and complex states in collaboration with another self-organizing system. Critically understanding how the mutual regulation of affect functions to create dyadic states of consciousness also can help us understand what produces change in the therapeutic process. © 1998 Michigan Association for Infant Mental Health     

Implicit relational knowing: Its role in development and psychoanalytic treatment

It is increasingly apparent that “something more” than interpretation is needed to bring about change in psychoanalytic treatment. Drawing on clinical and developmental observations, we propose that interactional processes from birth onward give rise to a form of procedural knowledge regarding how to do things with intimate others, knowledge we call implicit relational knowing. This knowing is distinct from conscious verbalizable knowledge and from the dynamic unconscious. The implicit relational knowing of patient and therapist intersect to create an intersubjective field that includes reasonably accurate sensings of each person's ways of being with others, sensings we call the “real relationship.” This intersubjective field becomes more complex and articulated with repeated patient–therapist encounters, giving rise to emergent new possibilities for more coherent and adaptive forms of interaction. During a transactional event that we term a “moment of meeting,” a new dyadic possibility crystallizes when the two persons achieve the dual goals of complementary fitted actions and joint intersubjective recognition in a new form. We argue that such moments of meeting shift the relational anticipations of each partner and allow for new forms of agency and shared experience to be expressed and elaborated. © 1998 Michigan Association for Infant Mental Health     

Toward a unified fielder theory: what we do not yet know about how people run to catch a ball.

Linear optic trajectory theory claims that people catch balls by running in a direction that keeps an optic trajectory of the ball linear. The authors show a range of ball trajectories for which departures of the optic trajectory from linearity do not predict which direction people will run, and the direction they choose does not correct these departures. Data from a wide range of ball trajectories show that people run so that the angle of elevation of gaze to the ball increases at a decreasing rate. But it is not yet known why people choose the particular path they do from the many that would achieve this.     

The application of an action system model to destructive behaviour: the examples of arson and terrorism.

This article argues that criminal and deviant behaviour can be productively viewed through an action system framework. The idea is developed by considering two forms of destructive behaviour: arson and barricade-hostage terrorist incidents. Two studies are presented. The first study tests the hypothesis that different forms of arson will reflect the four dominant states that an action system can take; integrative, expressive, conservative, and adaptive. A smallest space analysis was performed on 46 variables describing 230 cases of arson and the results identified the four themes of action system functioning. An examination of the personal characteristics of the arsonists also produced four variable groupings and a combined analysis of the four action scales and four characteristics scales also supported the structural hypothesis of the action system model. The second study applied the action system model to the study acts of terrorist barricade-hostage incidents. A smallest space analysis of 44 variables coded from 41 incidents again revealed four distinct forms of activity, which were psychologically similar to the four modes of arson identified in study one. Overall, these two studies provide support for the appropriateness of the action system framework as a way of classifying different forms of deviant behaviour.     

Reliability and Validity of Three Measures of Multicultural Competency

The purpose of this study was to examine the reliability and validity of 3 measures of multicultural competency, the Multicultural Counseling Awareness Scale: Form B (MCAS), the Multicultural Awareness‐Knowledge‐and‐Skills Survey (MAKSS), and the Survey of Graduate Students' Experiences with Diversity (GSEDS). Data were collected from 120 master's‐level students from counseling programs accredited by the Council for Accreditation of Counseling and Related Educational Programs or the equivalent. The findings generally support the psychometric soundness of these surveys, with some important exceptions. Guidelines for their use and directions for additional research are provided.     

萨班对摩诃衍遗教的批判

David Seyfort Reugg说,摩诃衍在吐蕃僧诤中失败的记录系萨迦班智达伪造的。其实,萨班在这个事件上的说法之所以成为一种权威,并不在于基本事实上的出新,而在于他的论述有力。他较早站在因明的立场来分析双方的"见地"与"修行",立意既高,便影响深远。萨班对摩诃衍和大手印的批判,我们不应该仅仅评判其是非,而应关注他的出发点,即他所面对的藏传佛教的因缘。他的体系完整、次第井然的教言不仅满足了藏族社会的需要,而且一度成为大元帝国用来维系各个民族的精神纽带,是中华民族宝贵的精神遗产。     

Growth hormone response to different consecutive stress stimuli in healthy men: is there any difference?

The contribution of growth hormone (GH), released during acute and repeated stressful situations, to the development of stress-related disorders is often neglected. We have hypothesized that the modulation of the GH response to sequential stress exposure in humans depends mainly on the nature of the stressor. To test this hypothesis, we compared GH responses to different stressful situations, namely aerobic exercise, hypoglycemia and hyperthermia, which were applied in two sequential sessions separated by 80-150 min. In addition, administration of the dopaminergic drug apomorphine was used as a pharmacological stimulus. GH responses to submaximal exercise (bicycle ergometer, increasing work loads of 1.5, 2.0 and 2.5 W/kg, total duration 20 min) and hyperthermia in a sauna (80 degrees C, 30 min) were prevented when preceded by the same stress stimulus. Hypoglycemia induced by insulin (0.1 IU/kg intravenously) resulted in a significant GH response also during the second of the two consecutive insulin tests, though the response was reduced. Administration of apomorphine (0.75 mg subcutaneously) or insulin prevented the increase in GH release in response to a sequential bolus of apomorphine, while hypoglycemia induced a significant elevation in GH levels even if applied after a previous treatment with apomorphine. In conclusion, the feedback inhibition of the GH response to a sequential stress stimulus depends on the stimulus used. Unlike in the case of exercise and hyperthermia, mechanisms involved in the stress response to hypoglycemia appear to overcome the usual feedback mechanisms and to re-induce the GH response when applied after another stimulus.     

“Compliance” to “Concordance”: A Critical View

Advocates of “concordance” describe it as a new model of shared decision-making between physicians and patients based on a partnership of equals. “Concordance” is meant to make obsolete the notion of “compliance,” in which patients are seen as, ideally, following doctors’ orders. This essay offers a critical view of concordance, arguing that the literature itself on concordance, including materials at the web site of Medicines Partnership, the implementation arm in Great Britain of the concordance model, is full of contradiction; concordance, in fact, harbors an ideology of compliance. The essay suggests that an improvement in patient medication use will more likely come from a frank consideration of the relation of compliance issues and commercial ones, and that a key question across domains is, “how are patients/health agents/consumers persuaded to acquire certain drugs and take them as directed?”
