The Rewarding Aspects of Music Listening Are Related to Degree of Emotional Arousal

Background

Listening to music is amongst the most rewarding experiences for humans. Music has no functional resemblance to other rewarding stimuli, and has no demonstrated biological value, yet individuals continue listening to music for pleasure. It has been suggested that the pleasurable aspects of music listening are related to a change in emotional arousal, although this link has not been directly investigated. In this study, using methods of high temporal sensitivity we investigated whether there is a systematic relationship between dynamic increases in pleasure states and physiological indicators of emotional arousal, including changes in heart rate, respiration, electrodermal activity, body temperature, and blood volume pulse.

Methodology

Twenty-six participants listened to self-selected intensely pleasurable music and “neutral” music that was individually selected for them based on low pleasure ratings they provided on other participants'' music. The “chills” phenomenon was used to index intensely pleasurable responses to music. During music listening, continuous real-time recordings of subjective pleasure states and simultaneous recordings of sympathetic nervous system activity, an objective measure of emotional arousal, were obtained.

Principal Findings

Results revealed a strong positive correlation between ratings of pleasure and emotional arousal. Importantly, a dissociation was revealed as individuals who did not experience pleasure also showed no significant increases in emotional arousal.

Conclusions/Significance

These results have broader implications by demonstrating that strongly felt emotions could be rewarding in themselves in the absence of a physically tangible reward or a specific functional goal.     

THE PSYCHOTHERAPEUTIC APPROACH TO EMOTIONAL PROBLEMS

Physicians are confronted with more and more psychological problems in their daily practice. Not only must a physician be able to recognize the problems, he must also be prepared to treat a certain number of them. Some of the patients will improve just because of a good relationship with the physician. Others will require more definitive, yet comparatively simple, psychotherapy. On the other hand, some patients with clear-cut emotional problems are best treated by the physician''s traditional medical approach rather than by some type of “formal” psychotherapy. In some circumstances psychotherapeutic efforts may be damaging.     

The Mere Co-Presence: Synchronization of Autonomic Signals and Emotional Responses across Co-Present Individuals Not Engaged in Direct Interaction

Existing evidence suggests that in social contexts individuals become coupled in their emotions and behaviors. Furthermore, recent biological studies demonstrate that the physiological signals of interacting individuals become coupled as well, exhibiting temporally synchronized response patterns. However, it is yet unknown whether people can shape each other''s responses without the direct, face-to-face interaction. Here we investigated whether the convergence of physiological and emotional states can occur among “merely co-present” individuals, without direct interactional exchanges. To this end, we measured continuous autonomic signals and collected emotional responses of participants who watched emotional movies together, seated side-by-side. We found that the autonomic signals of co-present participants were idiosyncratically synchronized and that the degree of this synchronization was correlated with the convergence of their emotional responses. These findings suggest that moment-to-moment emotional transmissions, resulting in shared emotional experiences, can occur in the absence of direct communication and are mediated by autonomic synchronization.     

Patients' accounts of being removed from their general practitioner's list: qualitative study

Objective To explore patients'' accounts of being removed from a general practitioner''s list.Design Qualitative analysis of semistructured interviews.Setting Patients'' homes in Leicestershire.Participants 28 patients who had recently been removed from a general practitioner''s list.Results The removed patients gave an account of themselves as having genuine illnesses needing medical care. In putting their case that their removal was unjustified, patients were concerned to show that they were “good” patients who complied with the rules that they understood to govern the doctor-patient relationship: they tried to cope with their illness and follow medical advice, used general practice services “appropriately,” were uncomplaining, and were polite with doctors. Removed patients also used their accounts to characterise the removing general practitioner as one who broke the lay rules of the doctor-patient relationship. These “bad” general practitioners were rude, impersonal, uncaring, and clinically incompetent and lied to patients. Patients felt very threatened by being removed from their general practitioner''s list; they experienced removal as an attack on their right to be an NHS patient, as deeply distressing, and as stigmatising.Conclusions Removal is an overwhelmingly negative and distressing experience for patients. Many of the problems encountered by removed patients may be remediable through general practices having an explicit policy on removal and procedures in place to help with “difficult” patients.     

Nitrous Oxide Inhalation as a Fad—Dangers in Uncontrolled Sniffing for Psychedelic Effect

“LAUGHING GAS is the newest thing for kids seeking kicks,” the Stanford Daily reports. “They sniff it.”So begins a news story in the Los Angeles Times of 26 January 1967. The story continues:“It''s the latest way to travel, or so say a growing group of devotees on the campus,” the university student paper said. “It can produce much the same effects as psychedelic drugs, they claim, and it''s cheaper to obtain.”“One student said he buys the gas, nitrous oxide, from a medical supply house. `They think I am anesthetizing rats,'' he explained.“Campus medical authorities said the gas, sniffed `in sufficient amounts... could produce all the states of anesthesia, including the final stage—death.''”     

Methoxyflurane and Nitrous Oxide as Obstetric Analgesics. I.—A Comparison by Continuous Administration

Methoxyflurane and nitrous oxide have been compared as obstetric analgesics. The inhaled concentrations of these agents, given continuously, were adjusted by an anaesthetist to maintain each patient at the optimum state between reaction to pain and consciousness. Assessments were made continuously.Though the anaesthetist''s assessment showed no difference between the mean results, a greater proportion of the methoxyflurane patients were “satisfactory” for 90–100% of the time than of the nitrous oxide patients, particularly in regard to objective pain relief. The midwives'' opinion of those who had “complete” pain relief supported this. Nausea was significantly less among methoxyflurane patients, and vomiting during labour occurred only in patients who had nitrous oxide. It is concluded that nitrous oxide and methoxyflurane given in a continuously adjusted concentration are almost equally effective as obstetric analgesics, though there are certain features which favour methoxyflurane.     

The Expression of Emotions in 20th Century Books

We report here trends in the usage of “mood” words, that is, words carrying emotional content, in 20th century English language books, using the data set provided by Google that includes word frequencies in roughly 4% of all books published up to the year 2008. We find evidence for distinct historical periods of positive and negative moods, underlain by a general decrease in the use of emotion-related words through time. Finally, we show that, in books, American English has become decidedly more “emotional” than British English in the last half-century, as a part of a more general increase of the stylistic divergence between the two variants of English language.     

PSYCHOSURGERY—Present Indications and Future Prospects

Although the advent and widespread use of ataractic drugs has more or less eclipsed lobotomy as a method of dealing with severe psychotic states, variations and adaptations of the operation still can be used with benefit in certain pretty well defined circumstances.“Chemical lobotomy” and regressive electroshock bring about alterations in behavior superficially resembling those of lobotomy, but without the changes in personality that are the object of lobotomy. These desirable changes consist in increased extraversion, decreased preoccupation with self and decreased sensitivity to the opinions of others. With restricted operations, undesirable changes—the “frontal lobe syndrome”—do not occur.Operative failures are due to three main causes: (a) Preoperative emotional deterioration; (b) progress of the underlying disease; (c) relapse, possibly due to inadequate operation.Lobotomy is advisable if the patient does not show sustained improvement after a year of active treatment by other indicated means. The operation often represents the turning point in effective treatment. After the first year of ineffective treatment valuable time is being lost, with danger of fixation and deterioration. Then it is safer to operate than to wait.The future of psychosurgery lies in prompt application, in favorable patients, of selective operations that will reverse the trend of illness.There is particular need for further exploration of the temporal lobes in the hope of finding some procedure that will suppress hallucinations. Some 90 per cent of patients remaining in hospitals after psychosurgery are experiencing hallucinations. If these phenomena can be eliminated without producing serious personality defects, another large field for the application of psychosurgery will be opened.     

Psychiatric Illness in General Practice: A Detailed Study Using a New Method of Case Identification

A self-administered questionary (the General Health Questionnaire) aimed at detecting current psychiatric disturbance was given to 553 consecutive attenders to a general practitioner''s surgery. A sample of 200 of these patients was given an independent assessment of their mental state by a psychiatrist using a standardized psychiatric interview. Over 90% of the patients were correctly classified as “well” or “ill” by the questionary, and the correlation between questionary score and the clinical assessment of severity of disturbance was found to be +0·80.The “conspicuous psychiatric morbidity” of a suburban general practice assessed by a general practitioner who was himself a psychiatrist and validated against independent psychiatric assessment was found to be 20%. “Hidden psychiatric morbidity” was found to account for one-third of all disturbed patients. These patients were similar to patients with “conspicuous illnesses” in terms both of degree of disturbance and the course of their illnesses at six-month follow-up, but were distinguished by their attitude to their illness and by usually presenting a physical symptom to the general practitioner.When 87 patients who had been assessed as psychiatric cases at the index consultation were called back for follow-up six months later, two-thirds of them were functioning in the normal range. Frequency of attendance at the surgery in the six months following index consultation was found to have only a modest relationship to severity of psychiatric disturbance.It is argued that minor affective illnesses and physical complaints often accompany each other and usually have a good prognosis.     

Systems biology approach to developing S2RM-based “systems therapeutics” and naturally induced pluripotent stem cells

The degree to, and the mechanisms through, which stem cells are able to build, maintain, and heal the body have only recently begun to be understood. Much of the stem cell’s power resides in the release of a multitude of molecules, called stem cell released molecules (SRM). A fundamentally new type of therapeutic, namely “systems therapeutic”, can be realized by reverse engineering the mechanisms of the SRM processes. Recent data demonstrates that the composition of the SRM is different for each type of stem cell, as well as for different states of each cell type. Although systems biology has been successfully used to analyze multiple pathways, the approach is often used to develop a small molecule interacting at only one pathway in the system. A new model is emerging in biology where systems biology is used to develop a new technology acting at multiple pathways called “systems therapeutics”. A natural set of healing pathways in the human that uses SRM is instructive and of practical use in developing systems therapeutics. Endogenous SRM processes in the human body use a combination of SRM from two or more stem cell types, designated as S²RM, doing so under various state dependent conditions for each cell type. Here we describe our approach in using state-dependent SRM from two or more stem cell types, S²RM technology, to develop a new class of therapeutics called “systems therapeutics.” Given the ubiquitous and powerful nature of innate S²RM-based healing in the human body, this “systems therapeutic” approach using S²RM technology will be important for the development of anti-cancer therapeutics, antimicrobials, wound care products and procedures, and a number of other therapeutics for many indications.     

Analysis and Prediction of the Metabolic Stability of Proteins Based on Their Sequential Features,Subcellular Locations and Interaction Networks

The metabolic stability is a very important idiosyncracy of proteins that is related to their global flexibility, intramolecular fluctuations, various internal dynamic processes, as well as many marvelous biological functions. Determination of protein''s metabolic stability would provide us with useful information for in-depth understanding of the dynamic action mechanisms of proteins. Although several experimental methods have been developed to measure protein''s metabolic stability, they are time-consuming and more expensive. Reported in this paper is a computational method, which is featured by (1) integrating various properties of proteins, such as biochemical and physicochemical properties, subcellular locations, network properties and protein complex property, (2) using the mRMR (Maximum Relevance & Minimum Redundancy) principle and the IFS (Incremental Feature Selection) procedure to optimize the prediction engine, and (3) being able to identify proteins among the four types: “short”, “medium”, “long”, and “extra-long” half-life spans. It was revealed through our analysis that the following seven characters played major roles in determining the stability of proteins: (1) KEGG enrichment scores of the protein and its neighbors in network, (2) subcellular locations, (3) polarity, (4) amino acids composition, (5) hydrophobicity, (6) secondary structure propensity, and (7) the number of protein complexes the protein involved. It was observed that there was an intriguing correlation between the predicted metabolic stability of some proteins and the real half-life of the drugs designed to target them. These findings might provide useful insights for designing protein-stability-relevant drugs. The computational method can also be used as a large-scale tool for annotating the metabolic stability for the avalanche of protein sequences generated in the post-genomic age.     

The Relationship between Trait Emotional Intelligence and Interaction with Ostracized Others' Retaliation

Background

Regulation of emotions in others is distinct from other activities related to trait emotional intelligence in that only such behavior can directly change other people''s psychological states. Although emotional intelligence has generally been associated with prosociality, emotionally intelligent people may manipulate others'' behaviors to suit their own interests using high-level capabilities to read and manage the emotions of others. This study investigated how trait emotional intelligence was related to interacting with ostracized others who attempt retaliation.

Method

We experimentally manipulated whether two people were simultaneously ostracized or not by using an online ball-tossing game called Cyberball. Eighty university students participated in Cyberball for manipulating ostracism and a “recommendation game,” a variation of the ultimatum game for assessing how to interact with others who attempt retaliation, with four participants. After the recommendation game, participants rated their intention to retaliate during the game.

Results

People with higher interpersonal emotional intelligence were more likely to recommend that the ostracized other should inhibit retaliation and maximize additional rewards when they have a weaker intention to retaliate. However, they were more likely to recommend that the ostracized other should retaliate against the ostracizers when they have a stronger intention to retaliate.

Conclusion

This is the first laboratory study that empirically reveals that people with high interpersonal emotional intelligence influence others'' emotions based on their own goals contrary to the general view. Trait emotional intelligence itself is neither positive nor negative, but it can facilitate interpersonal behaviors for achieving goals. Our study offers valuable contributions for the refinement of the trait emotional intelligence concept in the respect of its social function.     

Social cognition and psychopathology: a critical overview

The philosophical and interdisciplinary debate about the nature of social cognition, and the processes involved, has important implications for psychiatry. On one account, mindreading depends on making theoretical inferences about another person''s mental states based on knowledge of folk psychology, the so-called “theory theory” (TT). On a different account, “simulation theory” (ST), mindreading depends on simulating the other''s mental states within one''s own mental or motor system. A third approach, “interaction theory” (IT), looks to embodied processes (involving movement, gesture, facial expression, vocal intonation, etc.) and the dynamics of intersubjective interactions (joint attention, joint action, and processes not confined to an individual system) in highly contextualized situations to explain social cognition, and disruptions of these processes in some psychopathological conditions. In this paper, we present a brief summary of these three theoretical frameworks (TT, ST, IT). We then focus on impaired social abilities in autism and schizophrenia from the perspective of the three approaches. We discuss the limitations of such approaches in the scientific studies of these and other pathologies, and we close with a short reflection on the future of the field. In this regard we argue that, to the extent that TT, ST and IT offer explanations that capture different (limited) aspects of social cognition, a pluralist approach might be best.     

Physicians' Own Health—Some Advice for the Advisors

Information about physicians'' health and health practices is sparse and scattered. With a few exceptions, however—notably suicide and substance abuse—it appears that physicians'' health and health-promotion activities are at least similar to those of the general public. In some areas, such as smoking cessation, physicians have far outstripped the general public. As physicians gain more insight into their own health and health habits, advice to patients can be realistic and effective. Indeed, several personal health activities, including immunization, have direct, salutary impacts on patient care. Physicians should analyze and change their own health practices as indicated and pay special attention to “high yield” health habits, such as seat-belt use.     

Admissions to Hospital due to Drugs

In a survey of adverse drug reactions in wards of two Belfast hospitals for 52 weeks in 1965–6, 2·9% of 1,268 patients seen were admitted to hospital because of adverse reactions to drugs taken for therapeutic reasons and 2·1% were admitted because of self-poisoning. Patients admitted because of adverse drug reactions were older than those admitted because of self-poisoning and stayed in hospital longer. Among the drugs which caused the adverse reactions were digitalis preparations, antibiotics, corticosteroids, anticoagulants, analgesics, and tranquillizers. Hypersensitivity and side-effect types of reactions were the most common. Barbiturates were the most frequently used drugs in suicidal attempts.
