情绪标注对负性情绪的抑制：来自自主神经活动的证据*

在情绪标注的研究中,存在着情绪标注是增强还是抑制负性情绪以及非情绪标注能否抑制负性情绪的争论。研究选择负性情绪面孔和图片为实验材料,以女大学生为被试,采用了16导生理记录仪记录其完成任务时皮电、指温和指脉率上的变化。实验1以负性情绪面孔为材料,采用经典范式试图验证以往研究结果。实验2采用负性情绪图片为材料,探讨了情绪标注和非情绪标注对负性情绪的抑制作用。结果发现：(1)在情绪标注条件下被试的指脉率比情绪匹配条件下的更低;性别标注(即非情绪标注)条件下被试的指脉率与性别匹配条件下的差异不显著;(2)在情绪标注条件下被试的指温比自然或人工标注条件(即非情绪标注)下的更高。研究结果表明,情绪标注可以抑制负性情绪,而非情绪标注则不能抑制负性情绪。     

Affect Labeling to Facilitate Inhibitory Learning: Clinical Considerations

Exposure-based treatments known to be effective for a wide range of psychopathology are thought to work via inhibitory learning, where new learning acquired during exposure exercises inhibits previously learned fear and avoidance responses. One way in which this inhibitory learning may be enhanced is through affect labeling, during which clients verbalize their internal emotional experiences. Theoretically, affect labeling may be a subtle, implicit form of emotion regulation and may facilitate more explicit forms of extinction learning. Experimental research suggests that affect labeling may lead to attenuated fear responses to emotionally evocative stimuli in healthy samples and may be a helpful strategy in reducing physiological arousal experienced during exposure tasks, particularly for clients with inhibitory deficits. Research with clinical samples is limited and mixed, at best. Case examples illustrate how affective labeling may help get a client “unstuck” from unproductive processing loops, can contribute to shifts in perspective and meaning making, and may modulate distress and promote distress tolerance. We argue that routine use of affect labeling in clinical care is premature. When used, it should be employed strategically within a broader case conceptualization and may be of a limited benefit beyond what is already employed in quality exposure therapy.

THE EFFECTS OF ECHOLALIA ON ACQUISITION AND GENERALIZATION OF RECEPTIVE LABELING IN AUTISTIC CHILDREN

This investigation, consisting of two experiments, was designed to assess the effects of autistic immediate echolalia on acquisition and generalization of receptive labeling tasks. Experiment 1 addressed whether autistic children could use their echolalia to facilitate acquisition. The results indicated that incorporating echolalia (echo of the requested object's label) into the task before manual response (handing the requested object to the experimenter) facilitated receptive labeling. Experiment 2 was designed to determine the effects of incorporating echolalia into task response on acquisition and subsequent generalization. These results indicated that echolalia facilitated generalization for echolalic autistic children but not for functionally mute autistic children. The results of the experiments are discussed in terms of stimulus control. Additionally, it is proposed that perhaps in certain cases, echolalia should not be eliminated, but used to advantage in receptive responding.     

The Emotion Mapping Activity: Preliminary evaluation of a mindfulness‐informed exercise to improve emotion labeling in alexithymic persons

Alexithymia is a psychoemotional trait associated with many treatment‐resistant psychological and social difficulties. Research suggests that these difficulties stem primarily from an inability to appropriately apply linguistic labels to emotional experiences and content. The present research introduces and preliminarily evaluates a novel mindfulness‐informed exercise to improve emotion‐labeling ability in alexithymic persons. Based in culturally universal patterns of somatic experience, the Emotion Mapping Activity (EMA ) directs alexithymic persons to reflect on their internal, somatic experiences as a source of information for interpreting and labeling emotional experiences. In the present study, 67 alexithymic persons completed a series of emotion‐labeling tasks either with or without assistance of the EMA . Results suggest that completion of the EMA may improve ability to label emotions that would be otherwise misinterpreted – without interfering with labeling that is already intact. Though further research is necessary, the present study suggests that the EMA may hold the potential to be incorporated into psychotherapy protocols as an exercise for improving emotion‐labeling ability in alexithymic clients.     

Enhanced proliferation of progenitor cells following long-term potentiation induction in the rat dentate gyrus

The dentate gyrus (DG) is among the few areas in the mammalian brain where production of new neurons continues in the adulthood. Although its functional significance is not completely understood, several lines of evidence suggest the role of DG neurogenesis in learning and memory. Considering that long-term potentiation (LTP) is a prime candidate for the process underlying hippocampal learning and memory, these results raise the possibility that LTP and neurogenesis are closely related. Here, we investigated whether or not LTP induction in the afferent pathway triggers enhanced proliferation of progenitor cells in the DG. LTP was induced by tetanic stimulation in perforant path-DG synapses in one hemisphere, and the number of newly generated progenitor (BrdU-labeled) cells in the DG was quantified. Compared with the control hemisphere (stimulated with low-frequency pulses), the LTP-induced hemisphere contained a significantly higher number of newly generated progenitor cells in the dorsal as well as ventral DG. When CPP, an NMDA receptor antagonist, was administered, tetanic stimulation neither induced LTP nor enhanced progenitor cell proliferation, indicating that NMDA receptor activation, rather than tetanic stimulation per se, is responsible for enhanced progenitor proliferation in the control animal. Our results show that tetanic stimulation of perforant path sufficient to induce LTP increases progenitor proliferation in adult DG in an NMDA receptor-dependent manner.     

The effects of labelling,expert testimony,and information processing mode on juror decisions in SVP civil commitment trials

Expert witnesses offering testimony in sexually violent predator civil commitment trials may use diagnostic labels that are either familiar (e.g. ‘psychopath’) or unfamiliar (e.g. ‘paraphilia’) to jurors. Using predictions based on cognitive experiential self-theory, we explored the influence of testimony type (clinical versus actuarial) and diagnostic label (psychopath versus paraphilia) on jurors motivated to adopt either an experiential processing mode (PM; in which heuristic cues may be strongly relied upon) or an analytic rational PM. Consistent with previous research, our results indicated that when given a psychopathic diagnostic label, mock jurors motivated to process information experientially were more influenced by clinical testimony, whereas mock jurors induced into a rational mode were more influenced by actuarial testimony. However, experientially oriented jurors given a paraphilia diagnostic label did not show the expected influence of clinical expert testimony, and instead were more persuaded by actuarial testimony. These findings are discussed from a judgement and heuristics cues framework. The implications of several procedural suggestions are examined. Copyright © 2009 John Wiley & Sons, Ltd.

A comparison of methods for teaching receptive labeling to children with autism spectrum disorders

Many early intervention curricular manuals recommend teaching auditory-visual conditional discriminations (i.e., receptive labeling) using the simple-conditional method in which component simple discriminations are taught in isolation and in the presence of a distracter stimulus before the learner is required to respond conditionally. Some have argued that this procedure might be susceptible to faulty stimulus control such as stimulus overselectivity (Green, 2001). Consequently, there has been a call for the use of alternative teaching procedures such as the conditional-only method, which involves conditional discrimination training from the onset of intervention. The purpose of the present study was to compare the simple-conditional and conditional-only methods for teaching receptive labeling to 3 young children diagnosed with autism spectrum disorders. The data indicated that the conditional-only method was a more reliable and efficient teaching procedure. In addition, several error patterns emerged during training using the simple-conditional method. The implications of the results with respect to current teaching practices in early intervention programs are discussed.     

Don't Count Calorie Labeling Out: Calorie Counts on the Left Side of Menu Items Lead to Lower Calorie Food Choices

Providing calorie counts on restaurants’ menus/menu boards is one of the most prominent policy interventions that has been implemented to combat the obesity epidemic in America. However, previous research across multiple disciplines has found little effect of providing calorie counts on calories ordered, leading some to call calorie provision a failed policy. The authors propose that this failure is partly due to not considering how people process information when making food choices: Americans read from left‐to‐right, processing calorie information only after processing the food item's name. Thus, the authors test a simple way to improve the effectiveness of calorie counts: display calorie counts to the left (vs. right) of food items. A field study and a laboratory study with American participants found that calorie counts to the left (vs. right) decreased calories ordered by 16.31%. A final laboratory study demonstrated that this effect is reversed among Hebrew‐speakers, who read from right‐to‐left, providing further evidence that the order in which calorie information is processed matters. Accordingly, calling calorie labeling a policy failure may be premature.
