  • How Should Neuroscience Study Emotions? by Distinguishing Emotion States, Concepts, and Experiences Ralph Adolphs

E-mail: [email protected] Abstract In this debate with Lisa Feldman Barrett, I defend a view of emotions as biological functional states. Affective neuroscience studies emotions in this sense, but it also studies the conscious experience of emotion (‘feelings’), our ability to attribute emotions to others and to animals (‘attribution’, ‘anthropomorphizing’), our ability to think and talk about emotion (‘concepts of emotion’, ‘semantic knowledge of emotion’) and the behaviors caused by an emotion (‘expression of emotions’, ‘emotional reactions’). I think that the most pressing challenge facing affective neuroscience is the need to carefully distinguish between these distinct aspects of ‘emotion’. I view emotion states as evolved functional states that regulate complex behavior, in both people and animals, in response to challenges that instantiate recurrent environmental themes. These functional states, in turn, can also cause conscious experiences (feelings), and their effects and our memories for those effects also contribute to our semantic

Davidson and William Irwin Recently, there has been a convergence in lesion and neuroimaging data in the identification of circuits underlying positive and negative emotion in the human brain. Emphasis is placed on the prefrontal cortex (PFC) and the amygdala as two key components of this circuitry. Emotion guides action and organizes behavior towards salient goals. To accomplish this, it is essential that the organism have a means of representing affect in the absence of immediate elicitors. It is proposed that the PFC plays a crucial role in affective working memory.

  • Empathy: a Social Cognitive Neuroscience Approach Lian T
    Social and Personality Psychology Compass 3/1 (2009): 94–110, 10.1111/j.1751-9004.2008.00154.x Empathy: A Social Cognitive Neuroscience Approach Lian T. Rameson* and Matthew D. Lieberman Department of Psychology, University of California, Los Angeles Abstract There has been recent widespread interest in the neural underpinnings of the experience of empathy. In this review, we take a social cognitive neuroscience approach to understanding the existing literature on the neuroscience of empathy. A growing body of work suggests that we come to understand and share in the experiences of others by commonly recruiting the same neural structures both during our own experience and while observing others undergoing the same experience. This literature supports a simulation theory of empathy, which proposes that we understand the thoughts and feelings of others by using our own mind as a model. In contrast, theory of mind research suggests that medial prefrontal regions are critical for understanding the minds of others. In this review, we offer ideas about how to integrate these two perspectives, point out unresolved issues in the literature, and suggest avenues for future research. In a way, most of our lives cannot really be called our own. We spend much of our time thinking about and reacting to the thoughts, feelings, intentions, and behaviors of others, and social psychology has demonstrated the manifold ways that our lives are shared with and shaped by our social relationships. It is a marker of the extreme sociality of our species that those who don’t much care for other people are at best labeled something unflattering like ‘hermit’, and at worst diagnosed with a disorder like ‘psychopathy’ or ‘autism’.

DS and LN thank Brian Knutson For in-depth discussions concerning several aspects of this paper. Conflicts of interest None Abstract Pleasure and reward are central for motivation, learning, feeling and allostasis. Although reward is without any doubt an affective phenomenon, there is no consensus concerning its relationship with emotion. In this mini-review we discuss this conceptual issue both from the perspective of theories of reward and emotion as well as human systems neuroimaging. We first describe how the reward process can be understood and dissected as intertwined with the emotion process, in particular in light of the appraisal theories, and then discuss how different facets of the reward process can be studied using neuroimaging and neurostimulation techniques. We conclude that future worK needs to focus on mapping the similarities and differences across stimuli and mechanisms that are involved in reward processing and in emotional processing, and propose that an integrative affective sciences approach would provide means for studying the emotional nature of reward.

Abstract Go to: Go to: Pain is a multidimensional experience that involves sensory, cognitive, and affective factors. The constellation of interactions between these factors renders the treatment of chronic pain challenging and financially burdensome. Further, the widespread use of opioids to treat chronic pain has led to an opioid epidemic characterized by exponential growth in opioid misuse and addiction. The staggering statistics related to opioid use highlight the importance of developing, testing, and validating fast- acting nonpharmacological approaches to treat pain. Mindfulness meditation is a technique that has been found to significantly reduce pain in experimental and clinical settings. The present review delineates findings from recent studies demonstrating that mindfulness meditation significantly attenuates pain through multiple, unique mechanisms—an important consideration for the millions of chronic pain patients seeking narcotic-free, self-facilitated pain therapy.

This study integrates mouse cursor motion analysis into affective computing and investigates the idea that movements of the computer cursor can provide information about emotion of the computer user. We extracted 16–26 trajectory features during a choice-reaching task and examined the link between emotion and cursor motions. Participants were induced for positive or negative emotions by music, film clips, or emotional pictures, and they indicated their emotions with questionnaires. Our 10-fold cross-validation analysis shows that statistical models formed from “known” partici- pants (training data) could predict nearly 10%–20% of the variance of positive affect and atten- tiveness ratings of “unknown” participants, suggesting that cursor movement patterns such as the area under curve and direction change help infer emotions of computer users.

  • An Affective Neuroscience Model of Boosting Resilience in Adults
    An Affective Neuroscience Model of Boosting Resilience in Adults Golnaz Tabibnia University of California, Irvine Correspondence should be addressed to: Golnaz Tabibnia Department of Psychological Science University of California, Irvine 4201 Social and Behavioral Sciences Gateway Irvine, CA 92697 (949) 824-3002 Fax [email protected] Page 1 of 123 Abstract Although research has identified dozens of behavioral and psychosocial strategies for boosting resilience in adults, little is known about the common underlying pathways. A comprehensive review of these strategies using an affective neuroscience approach indicates three distinct general routes to resilience (Fig. 1A): 1) down-regulating the negative (e.g., exposure, cognitive reappraisal) by reducing distress-related responses of the amygdala, hypothalamic-pituitary-adrenal axis, and autonomic nervous system; 2) up-regulating the positive (e.g., optimism, social connectedness) by activating mesostriatal reward pathways, which in turn can buffer the effects of stress; and 3) transcending the self (e.g., mindfulness, religious engagement) by reducing activation in the default mode network, a network associated with self-reflection, mind-wandering, and rumination. Some strategies (e.g., social support) can boost resilience via more than one pathway. Under- or over-stimulation of a pathway can result in vulnerability, such as over- stimulation of the reward pathway through substance abuse. This tripartite model of resilience-building is testable, accounts for a large body of data on adult resilience, and makes new predictions with implications for practice.

  • Cognitive Neuroscience Needs Affective Neuroscience (And Vice Versa)
    Brain and Cognition 42, 89±92 (2000) doi:10.1006/brcg.1999.1170, available online at http://www.idealibrary.com on Cognitive Neuroscience Needs Affective Neuroscience (and Vice Versa) Richard J. Davidson University of WisconsinÐMadison We are continuously being bombarded by a myriad of diverse sensory stimuli. Recollections from our past and re¯ections upon our future add to this cacophony and we need to select among the vast array of stimuli to which we are exposed and approach what is useful to meet our appetitive needs and withdraw from what is harmful so we avoid situations of threat or danger. The successful negotiation of these life challenges requires an intact cognitive and affective system. The purpose of this brief essay is to underscore the importance of affect to various components of cognition and hint at some of the major advances that have been made in its neuroscienti®c study. In its beginning, the cognitive revolution did not include feelings within its scienti®c purview. There was a clear sense among the leading scientists of this era that the major problems of cognition would yield to an experimen- tal and/or computational analysis that did not require emotion. The most striking evidence of this is simply the absence of very many references to emotion in the classic works of cognitive science and cognitive neuroscience that helped to de®ne the ®eld (e.g., Neisser, 1967). This feelingless stance, however, is now yielding to a more balanced analysis and a renewed appreci- ation for the role that affect might play in the basic mechanisms of cognition.

Box 217, 7500 AE Enschede, The Netherlands Karakter University Center, Radboud University Medical Center Nijmegen P.O. Box 9101, 6500 HB Nijmegen, The Netherlands [email protected] Abstract. To bring affective computing a leap forward, it is best to start with a step back. A century of research has been conducted on topics, which are crucial for affective computing. Understanding this vast amount of research will accelerate progress on affective comput- ing. Therefore, this article provides an overview of the history of affective computing. The complexity of affect will be described by discussing i) the relation between body and mind, ii) cognitive processes (i.e., attention, memory, and decision making), and iii) affective computing’s I/O. Sub- sequently, definitions are provided of affect and related constructs (i.e., emotion, mood, interpersonal stances, attitude, and personality traits) and of affective computing. Perhaps when these elements are embraced by the community of affective computing, it will us a step closer in bridg- ing its semantic gap. Keywords: affect, emotion, affective computing, biosignals, history, com- plexity, definitions, semantic gap. “The increasing tendency to ‘let’s see what the computer shows’ has dulled many investigators’ sensitivity to the basic rules of research, sometimes to the point that the definition of the problem is unclear. The speed and ease of statisti- cal computation, even of complex multivariate analysis involving Ns of 1000 or more, have tempted many investigators to submit all possible comparisons for analysis with little concern over the subtleties of multiple testing and the risk of type I errors.
