Interoceptive ability predicts aversion to losses

Emotions have been proposed to inform risky decision-making through the influence of affective physiological responses on subjective value. The ability to perceive internal body states, or “interoception” may influence this relationship. Here, we examined whether interoception predicts participants' degree of loss aversion, which has been previously linked to choice-related arousal responses. Participants performed both a heartbeat-detection task indexing interoception and a risky monetary decision-making task, from which loss aversion, risk attitudes and choice consistency were parametrically measured. Interoceptive ability correlated selectively with loss aversion and was unrelated to the other value parameters. This finding suggests that specific and separable component processes underlying valuation are shaped not only by our physiological responses, as shown in previous findings, but also by our interoceptive access to such signals.     

L’évaluation de la perte de chance en responsabilité médicale,une mission à repréciser pour l’Expert

Loss of opportunity, which today is considered as a prejudice in its own right, both for the French Supreme Court and the Council of State, remains undeniably difficult to assess in practice. For many years, the issue of compensation for breach of duty of disclosure gave the various courts the ability to roadtest this concept. However, although the criteria defining this concept, of judicial origin, have been established, the modus operandi allowing the judge to quantify it does not exist. How can this portion of personal injury be determined in relation to the size of the opportunity lost? This is primarily a technical issue, similar to that of assessing a disability rate. However, this request does not feature in typical common law missions for judicial or administrative medical expertise. The judge alone is left to assess this probability, whereas the expert would be in a position, as far as possible, to provide scientific and statistical assistance enabling a better definition of loss of opportunity.     

L’expertise médicale au temps des pandémies : l’exemple des cancers

Medical law suits were interrupted during the COVID-19 pandemia and judicial process will come shortly back to the normal. Pandemia induced delays in the cancer diagnosis and treatment. These modifications were validated by expert consensus from the medical societies. However in the coming years it is highly possible that patients think they were victims of a “loss of chance” and ask for a compensation. The various situations in which physicians can be involved are described and recommendations for the management of medical charts are discussed.     

‘Feeling the range’: Emotional geographies of sound in prisons

Sound, as a modality of emotion, is central to the everyday constitution of space. For an increasing population in Canada, however, incarceration forms the basis of everyday life. This paper explores the connections between sound and emotion as they play out in the under-researched context of prisons. I use a participant’s term, “feeling the range,” to identify the atmospheric, haptic, and emotive potential of sound as a vital tool of spatial knowledge. These conceptualisations inform three findings that highlight the enabling and constraining complexities of aurality. First, sound and listening are epistemological practices that offer important tools for spatial orientation in otherwise restrictive environments; yet some materialities of sound, like reverberation, also cause great disorientation. Secondly, the extensive capacities of sound enable connection with other beings and contexts during imprisonment; at the same time, sonic practices also disconnect, particularly through sonic techniques that carve out individualised auditory spaces. Finally, sound plays a crucial role in the enactment of power through resistance, and is used to reclaim dignity in undignified settings. This paper demonstrates that soundworlds can be as inclusive as they are exclusive, as convivial as they are hostile, and as therapeutic as they are torturous.     

Cognitive and emotional aspects of self-regulation in preschoolers

The goal of the present study was to examine the contribution of executive function (EF) and social cognition to individual differences in emotion regulation (ER) in preschool children. Sixty 3-, 4-, and 5-year-old children were administered a battery of EF tasks, two theory of mind tasks, a measure of verbal ability, and an ER task. In addition, parents completed the Behavior Rating Inventory of Executive Functioning—Preschool Version (BRIEF-P). Performance on the theory of mind tasks as well as parental ratings of executive function was not related to performance on the ER task. However, a component of EF (i.e., inhibition) approached significance with children's displays of positive behaviors during the ER task. Verbal ability was related to the regulation of positive but not negative emotions. Parental ratings of shifting accounted for a significant amount of variance in parental ratings of ER, even after controlling for verbal ability. The findings are discussed in the context of different conceptualizations of the developmental relation between ER and EF.     

The contributory role of worry in emotion generation and dysregulation in generalized anxiety disorder

The role of worry in generalized anxiety disorder (GAD) has been posited to serve as an avoidance of emotional experience, and emotion regulation deficits in GAD have been found in several previous studies. It remains unclear whether those with GAD experience more dysregulated emotions during periods of euthymia and positive affect or whether these deficits occur only during periods of worry. Individuals with GAD (with and without co-occurring dysphoria) and non-anxious controls were randomly assigned to receive a worry, neutral, or relaxation induction. Following the induction, all participants viewed a film clip documented to elicit sadness. Intensity of emotions and emotion regulation were examined following the induction period and film clip. The results revealed that, regardless of co-occurring dysphoria, individuals with GAD in the worry condition experienced more intense depressed affect than GAD participants in the other conditions and controls participants. In contrast, presence of worry appeared to have less impact on indices of emotion dysregulation, which were greater in participants with GAD compared to controls, but largely insensitive to contextual effects of worry or of relaxation. Following film viewing, both GAD participants with and without dysphoria displayed poorer understanding, acceptance, and management of emotions than did controls. However, acceptance and management deficits were most pronounced in individuals with both GAD and co-occurring dysphoria. Implications for the role of emotions in conceptualization and treatment of GAD are discussed.     

Measurement invariance of the Emotion Regulation Questionnaire (ERQ). A cross-national validity study

The goal of this research was to examine the measurement invariance of the Emotion Regulation Questionnaire (ERQ; Gross & John, 2003) across two European nations. Participants were Italian and German undergraduate students. First, confirmatory factor analysis was used to test for the two-factor structure of the ERQ; subsequently, measurement invariance was analysed. The results showed acceptable fit indices for the German and Italian sample; however, results with regard to the Italian sample showed lower fit indices than results regarding the German one. Measurement invariance of the ERQ across Italy and Germany was confirmed. Despite the fact that we assumed measurement invariance of the ERQ, future research is needed to deal with the lower fit regarding the Italian version.     

Role of medial prefrontal cortex in representing one’s own subjective emotional responses: A preliminary study

The medial prefrontal cortex (mPFC) has been implicated in attending to one’s own emotional states, but the role of emotional valence in this context is not understood. We examined valence-specific BOLD activity in a previously validated functional magnetic resonance imaging (fMRI) paradigm. Ten healthy subjects viewed emotional pictures and categorized their experience as pleasant, unpleasant or neutral. All three categories activated a common region within mPFC. Subtraction of neutral from pleasant or unpleasant conditions instead revealed ventromedial PFC (vmPFC), suggesting that this region represents emotional valence. During exteroceptive attention, greater mPFC responses were observed in response to emotional relative to neutral stimuli, consistent with studies implicating mPFC in the top-down modulation of emotion-biased attention. These findings may help to integrate the two proposed roles of mPFC in emotional representation and top-down modulation of subcortical structures.     

Neural processing of vocal emotion and identity

The voice is a marker of a person's identity which allows individual recognition even if the person is not in sight. Listening to a voice also affords inferences about the speaker's emotional state. Both these types of personal information are encoded in characteristic acoustic feature patterns analyzed within the auditory cortex. In the present study 16 volunteers listened to pairs of non-verbal voice stimuli with happy or sad valence in two different task conditions while event-related brain potentials (ERPs) were recorded. In an emotion matching task, participants indicated whether the expressed emotion of a target voice was congruent or incongruent with that of a (preceding) prime voice. In an identity matching task, participants indicated whether or not the prime and target voice belonged to the same person. Effects based on emotion expressed occurred earlier than those based on voice identity. Specifically, P2 (approximately 200 ms)-amplitudes were reduced for happy voices when primed by happy voices. Identity match effects, by contrast, did not start until around 300 ms. These results show an early task-specific emotion-based influence on the early stages of auditory sensory processing.     

The facilitative effect of positive stimuli on 3-year-olds’ flexible rule use

This study examined the effect of emotional stimuli on 3- to 4-year old children's flexible rule use, as measured by the Dimensional Change Card Sort (DCCS). In Experiment 1, children in two countries (Canada and China) were given 2 versions of the DCCS. The Standard version required children to sort red and blue boats and rabbits first by shape and then by color (or vice versa); the Emotional Faces version required children to sort happy and sad male and female faces first by emotion and then by gender (or vice versa). Children performed significantly better on the Emotional Faces version, and performance on the 2 versions was related. Order in which dimensions were presented had no effect. Experiment 2 examined which aspects of the emotional faces were responsible for the facilitation of children's performance. Performance on the Standard version was compared to performance on three contextual faces versions, in which children were shown happy, sad, or neutral faces and required to sort them by age (child versus adult) and then by gender (or vice versa). Facilitation was only seen in the context of happy faces. Results are consistent with the suggestion that positive stimuli promote cognitive flexibility, perhaps by increasing dopamine levels in prefrontal cortex.     

Emotion development system by interacting with human EEG and natural scene understanding

In this paper, we propose a mental development system for understanding the emotional status of humans, and sharing emotions with human subjects. According to the relationship between emotional factors and characteristics of an image, we incorporate the fuzzy concept to extract emotional features using L^*C^*H^* color and orientation information. On the other hand, we also consider the EEG signals which are stimulated by natural stimuli to form the semantic emotional features as well. Emotionally relevant features are firstly clustered into two categories with degrees of belongingness to each cluster to initialize the membership functions of a neuro-fuzzy system. The IF-THEN rules of a neuro-fuzzy system to understand the positive and negative human emotions will be constructed by interacting with human. Then the system attempts to extend the number of understandable emotion. Through the time, the system sub-clusters the emotional features so that the number of membership function of the neuro-fuzzy network will increase to incorporate more complicated human expertise considering more human emotions. Using such a developmental process, the proposed system can develop a mental ability to understand more complex human emotions by mining the characteristics of emotional features and interacting with its environment.     

独乐乐与众乐乐？社会与非社会正性情绪刺激的加工差异：一个ERP研究

个体情绪加工具有其生物基础,也受到文化因素的影响。社会性和非社会性情绪刺激加工可能存在不同的机制。然而,以往大多数研究主要关注负性情绪的加工差异。因此,本研究选取大学生被试20名采用图片感知范式（Picture Perception Paradigm）探讨个体在加工社会性和非社会性正性情绪刺激的脑电位活动差异。研究发现：（1）在P1成分上,情绪图片诱发的波幅要显著大于中性图片。（2）在N2成分上,正性社会情绪图片诱发的波幅要显著大于正性非社会情绪图片（3）在早期时间窗中,由正性社会情绪图片与非社会情绪图片诱发的LPP波幅差异不显著。在中期时间窗中,正性社会情绪图片与非社会情绪图片的LPP波幅差异显著。晚期时间窗中,正性社会情绪图片诱发的LPP波幅显著大于正性非社会情绪图片。由此,相对于非社会性请刺激来说,正性社会情绪刺激在加工上可能占据优势地位。     

Measuring and testing awareness of emotional face expressions

Comparison of behavioural measures of consciousness has attracted much attention recently. In a recent article, Szczepanowski et al. conclude that confidence ratings (CR) predict accuracy better than both the perceptual awareness scale (PAS) and post-decision wagering (PDW) when using stimuli with emotional content (fearful vs. neutral faces). Although we find the study interesting, we disagree with the conclusion that CR is superior to PAS because of two methodological issues. First, the conclusion is not based on a formal test. We performed this test and found no evidence that CR predicted accuracy better than PAS (p = .4). Second, Szczepanowski et al. used the present version of PAS in a manner somewhat different from how it was originally intended, and the participants may not have been adequately instructed. We end our commentary with a set of recommendations for future studies using PAS.
