Recognition of all basic emotions varies in accuracy and reaction time: A new verbal method of measurement

To study different aspects of facial emotion recognition, valid methods are needed. The more widespread methods have some limitations. We propose a more ecological method that consists of presenting dynamic faces and measuring verbal reaction times. We presented 120 video clips depicting a gradual change from a neutral expression to a basic emotion (anger, disgust, fear, happiness, sadness and surprise), and recorded hit rates and reaction times of verbal labelling of emotions. Our results showed that verbal responses to six basic emotions differed in hit rates and reaction times: happiness > surprise > disgust > anger > sadness > fear (this means these emotional responses were more accurate and faster). Generally, our data are in accordance with previous findings, but our differentiation of responses is better than the data from previous experiments on six basic emotions.     

Basic emotions elicited by odors and pictures

The sense of olfaction is often reported to have a special relationship with emotional processing. Memories triggered by olfactory cues often have a very emotional load. On the other hand, basic negative or positive emotional states should be sufficient to cover the most significant functions of the olfactory system including ingestion, hazard avoidance, and social communication. Thus, we investigated whether different basic emotions can be evoked in healthy people through the sense of olfaction. We asked 119 participants which odor evokes one of the six basic emotions (happiness, disgust, anger, anxiety, sadness, and surprise); another 97 participants were asked about pictures evoking those emotions. The results showed that almost every participant could name an olfactory elicitor for happiness or disgust. Olfactory elicitors of anxiety were reported less frequently, but they were still reported by three-quarters of the participants. However, for sadness and anger only about half of the participants reported an olfactory elicitor, whereas significantly more named a visual cue. Olfactory emotion elicitors were mainly related to the classes of culture, plants, and food, and visual emotion elicitors were largely related to humans. This data supports the hypothesis that in the vast majority of people, few differentiated emotions can be elicited through the olfactory channel. These emotions are happiness, disgust, and anxiety.     

Interoceptive sensitivity predicts sensitivity to the emotions of others

Some theories of emotion emphasise a close relationship between interoception and subjective experiences of emotion. In this study, we used facial expressions to examine whether interoceptive sensibility modulated emotional experience in a social context. Interoceptive sensibility was measured using the heartbeat detection task. To estimate individual emotional sensitivity, we made morphed photos that ranged between a neutral and an emotional facial expression (i.e., anger, sadness, disgust and happy). Recognition rates of particular emotions from these photos were calculated and considered as emotional sensitivity thresholds. Our results indicate that participants with accurate interoceptive awareness are sensitive to the emotions of others, especially for expressions of sadness and happy. We also found that false responses to sad faces were closely related with an individual's degree of social anxiety. These results suggest that interoceptive awareness modulates the intensity of the subjective experience of emotion and affects individual traits related to emotion processing.     

Emotional reactions to crime across cultures

Information about the emotions experienced by observers when they witness crimes would have important theoretical and practical implications, but to date no study has broadly assessed such emotional reactions. This study addressed this gap in the literature. Observers in seven countries viewed seven videos portraying actual crimes and rated their emotional reactions to each using 14 emotion scales. Observers reported significantly high levels of negative emotions including anger, contempt, disgust, fear and sadness‐related emotions, and anger, contempt and disgust were the most salient emotions experienced by viewers across all countries. Witnesses also reported significantly high levels of positive emotions as well (compared to not feeling the emotion at all), which was unexpected. Country moderated the emotion ratings; post‐hoc analyses indicated that masculine‐oriented cultures reported less nervousness, surprise, excitement, fear and embarrassment than feminine cultures.     

Mood-congruent false memories persist over time

There are two contrasting hypotheses that attempt to explain how emotion perception might be organised in the brain. One suggests that all emotions are lateralised to the right hemisphere whereas the other suggests that emotions may be differently lateralised according to valence. Here these two theories are contrasted, in addition to considering the role of emotional intensity in explaining possible differences in strength of lateralisation across emotions. Participants completed a Chimeric Faces Test for each of the six basic emotions: anger, disgust, fear, happiness, sadness and surprise. All emotions showed significant lateralisation to the right hemisphere, however, differences in strength of lateralisation within the right hemisphere were found. Stronger patterns of right hemisphere lateralisation were found for positive emotions and for emotions of higher intensity. The results support the right-hemisphere hypothesis, but suggest that there may be variability in organisation within the right hemisphere across different types of emotion.     

How aging affects the recognition of emotional speech

To successfully infer a speaker's emotional state, diverse sources of emotional information need to be decoded. The present study explored to what extent emotional speech recognition of 'basic' emotions (anger, disgust, fear, happiness, pleasant surprise, sadness) differs between different sex (male/female) and age (young/middle-aged) groups in a behavioural experiment. Participants were asked to identify the emotional prosody of a sentence as accurately as possible. As a secondary goal, the perceptual findings were examined in relation to acoustic properties of the sentences presented. Findings indicate that emotion recognition rates differ between the different categories tested and that these patterns varied significantly as a function of age, but not of sex.     

Spanish validation of an emotion-eliciting set of films

One of the main difficulties in the study of emotion is the induction of a real emotional response by means of artificial techniques. The aim of the current study is to validate the Spanish version of a set of films with the capacity to induce emotions (PIE) under laboratory conditions and to analyze its capacity to provoke differentiated basic emotions. A sample of 127 subjects took part in the study; 57 excerpts of Spanish-dubbed films with capacity in previous studies to induce 7 emotions: anger, fear, sadness, disgust, amusement, tenderness, and neutral emotion were used. Subjective emotional response was measured using the Self-Assessment Manikins and the Discrete Emotions Questionnaire. Films included showed a good capacity to induce positive and negative affects, high levels of emotional activation and variations in the perception of emotional control. They induced basic emotions of amusement and fear in a differentiated way. However, sadness and disgust could not be significantly differentiated from anger; or anger and tenderness from sadness. The PIE could be a useful tool for the experimental research of emotions in Spanish populations.     

The neural underpinnings of facial emotion recognition in ischemic stroke patients

Deficits in facial emotion recognition occur frequently after stroke, with adverse social and behavioural consequences. The aim of this study was to investigate the neural underpinnings of the recognition of emotional expressions, in particular of the distinct basic emotions (anger, disgust, fear, happiness, sadness and surprise). A group of 110 ischaemic stroke patients with lesions in (sub)cortical areas of the cerebrum was included. Emotion recognition was assessed with the Ekman 60 Faces Test of the FEEST. Patient data were compared to data of 162 matched healthy controls (HC’s). For the patients, whole brain voxel-based lesion–symptom mapping (VLSM) on 3-Tesla MRI images was performed. Results showed that patients performed significantly worse than HC’s on both overall recognition of emotions, and specifically of disgust, fear, sadness and surprise. VLSM showed significant lesion–symptom associations for FEEST total in the right fronto-temporal region. Additionally, VLSM for the distinct emotions showed, apart from overlapping brain regions (insula, putamen and Rolandic operculum), also regions related to specific emotions. These were: middle and superior temporal gyrus (anger); caudate nucleus (disgust); superior corona radiate white matter tract, superior longitudinal fasciculus and middle frontal gyrus (happiness) and inferior frontal gyrus (sadness). Our findings help in understanding how lesions in specific brain regions can selectively affect the recognition of the basic emotions.     

Emotion differentiation dissected: between-category,within-category,and integral emotion differentiation,and their relation to well-being

Emotion differentiation, the ability to describe and label our own emotions in a differentiated and specific manner, has been repeatedly associated with well-being. However, it is unclear exactly what type of differentiation is most strongly related to well-being: the ability to make fine-grained distinctions between emotions that are relatively closely related (e.g. anger and irritation), the ability to make larger distinctions between very distinct emotions (e.g. anger and sadness), or the combination of both. To determine which type of differentiation is most predictive of well-being, we performed a comprehensive meta-analysis across six datasets. We examined the correlations between these three types of differentiation and several indicators of well-being (depression, emotional clarity, and self-esteem). Results showed that individuals differentiated most between very distinct emotions and least between more related emotions, and that an index computed across emotions from both the same and different emotion categories was most strongly associated with well-being indicators.     

Similar patterns of age-related differences in emotion recognition from speech and music

Young and old adults’ ability to recognize emotions from vocal expressions and music performances was compared. The stimuli consisted of (a) acted speech (anger, disgust, fear, happiness, and sadness; each posed with both weak and strong emotion intensity), (b) synthesized speech (anger, fear, happiness, and sadness), and (c) short melodies played on the electric guitar (anger, fear, happiness, and sadness; each played with both weak and strong emotion intensity). The listeners’ recognition of discrete emotions and emotion intensity was assessed and the recognition rates were controlled for various response biases. Results showed emotion-specific age-related differences in recognition accuracy. Old adults consistently received significantly lower recognition rates for negative, but not for positive, emotions for both speech and music stimuli. Some age-related differences were also evident in the listeners’ ratings of emotion intensity. The results show the importance of considering individual emotions in studies on age-related differences in emotion recognition.     

Perceptual learning and recognition confusion reveal the underlying relationships among the six basic emotions

The six basic emotions (disgust, anger, fear, happiness, sadness, and surprise) have long been considered discrete categories that serve as the primary units of the emotion system. Yet recent evidence indicated underlying connections among them. Here we tested the underlying relationships among the six basic emotions using a perceptual learning procedure. This technique has the potential of causally changing participants’ emotion detection ability. We found that training on detecting a facial expression improved the performance not only on the trained expression but also on other expressions. Such a transfer effect was consistently demonstrated between disgust and anger detection as well as between fear and surprise detection in two experiments (Experiment 1A, n?=?70; Experiment 1B, n?=?42). Notably, training on any of the six emotions could improve happiness detection, while sadness detection could only be improved by training on sadness itself, suggesting the uniqueness of happiness and sadness. In an emotion recognition test using a large sample of Chinese participants (n?=?1748), the confusion between disgust and anger as well as between fear and surprise was further confirmed. Taken together, our study demonstrates that the “basic” emotions share some common psychological components, which might be the more basic units of the emotion system.     

Understanding emotional display rules at work and outside of work: The effects of country and gender

This study examined the long-held, but empirically untested assumption that emotional display rules at work are different from more general display rules. We examined whether the effect of context (work vs. non-work) on display rules depended on rater gender, rater country (i.e., Singapore, United States), and discrete emotion (anger, contempt, disgust, fear, sadness, and happiness). Results revealed that display rules at work involved less expressivity of emotion than did display rules outside of work for all six emotions. Further, display rules in Singapore involved less expressivity of anger, sadness, and fear than display rules in the US, with no country differences being observed for the emotions of happiness, contempt, and disgust. These results were qualified by significant country-by-gender interactions for anger, contempt, and disgust, a significant country-by-context interaction for fear, and a three-way interaction (i.e., country-by-gender-by-context) for sadness.     

Eliciting emotion ratings for a set of film clips: A preliminary archive for research in emotion

ABSTRACT

Film clips are commonly used to elicit subjectively experienced emotional states for many research purposes, but film clips currently available in databases are out of date, include a limited set of emotions, and/or pertain to only one conceptualization of emotion. This work reports validation data from two studies aimed to elicit basic and complex emotions (amusement, anger, anxiety, compassion, contentment, disgust, fear, happiness/joy, irritation, neutrality, pride, relief, sadness, surprise), equally distributed according to valence (positive, negative) and intensity (high, low). Participants rated film clips according to the degree of experienced emotion, and for valence and arousal. Our findings initiate an iterative archive of film clips shown here to discretely elicit 11 different emotions. Although further validation of these film clips is needed, ratings provided here should assist researchers in selecting potential film clips to meet the aims of their work.     

Young Offenders’ Emotion Recognition Dysfunction Across Emotion Intensities: Explaining Variation Using Psychopathic Traits,Conduct Disorder and Offense Severity

Antisocial individuals have problems recognizing negative emotions (e.g. Marsh & Blair in Neuroscience and Biobehavioral Reviews 32:454–465, 2009); however, due to issues with sampling and different methods used, previous findings have been varied. Sixty-three male young offenders and 37 age-, IQ- and socio-economic status-matched male controls completed a facial emotion recognition task, which measures recognition of happiness, sadness, fear, anger, disgust, and surprise and neutral expressions across 4 emotional intensities. Conduct disorder (YSR), and psychopathic and callous/unemotional traits (YPI) were measured, and offenders’ offense data were taken from the Youth Offending Service’s case files. Relative to controls, offenders were significantly worse at identifying sadness, low intensity disgust and high intensity fear. A significant interaction for anger was also observed, with offenders showing reduced low- but increased high-intensity anger recognition in comparison with controls. Within the young offenders levels of conduct disorder and psychopathic traits explained variation in sadness and disgust recognition, whereas offense severity explained variation in anger recognition. These results suggest that antisocial youths show specific problems in recognizing negative emotions and support the use of targeted emotion recognition interventions for problematic behavior.     

Bodily maps of emotions across child development

Different basic emotions (anger, fear, disgust, happiness, sadness, and surprise) are consistently associated with distinct bodily sensation maps, which may underlie subjectively felt emotions. Here we investigated the development of bodily sensations associated with basic emotions in 6‐ to 17‐year‐old children and adolescents (n = 331). Children as young as 6 years of age associated statistically discernible, discrete patterns of bodily sensations with happiness, fear, and surprise, as well as with emotional neutrality. The bodily sensation maps changed from less to more specific, adult‐like patterns as a function of age. We conclude that emotion‐related bodily sensations become increasingly discrete over child development. Developing awareness of their emotion‐related bodily sensations may shape the way children perceive, label, and interpret emotions.     

Assessment of perception of morphed facial expressions using the Emotion Recognition Task: Normative data from healthy participants aged 8–75

The ability to recognize and label emotional facial expressions is an important aspect of social cognition. However, existing paradigms to examine this ability present only static facial expressions, suffer from ceiling effects or have limited or no norms. A computerized test, the Emotion Recognition Task (ERT), was developed to overcome these difficulties. In this study, we examined the effects of age, sex, and intellectual ability on emotion perception using the ERT. In this test, emotional facial expressions are presented as morphs gradually expressing one of the six basic emotions from neutral to four levels of intensity (40%, 60%, 80%, and 100%). The task was administered in 373 healthy participants aged 8–75. In children aged 8–17, only small developmental effects were found for the emotions anger and happiness, in contrast to adults who showed age‐related decline on anger, fear, happiness, and sadness. Sex differences were present predominantly in the adult participants. IQ only minimally affected the perception of disgust in the children, while years of education were correlated with all emotions but surprise and disgust in the adult participants. A regression‐based approach was adopted to present age‐ and education‐ or IQ‐adjusted normative data for use in clinical practice. Previous studies using the ERT have demonstrated selective impairments on specific emotions in a variety of psychiatric, neurologic, or neurodegenerative patient groups, making the ERT a valuable addition to existing paradigms for the assessment of emotion perception.

Expression recognition and behavioural problems in early adolescence

The processing of emotional expressions is fundamental for normal socialisation and social interaction. Fifty-five children (aged 11–14 years) in mainstream education participated in this study. They were presented with a standardised set of pictures of facial expressions and asked to name one of the six emotions illustrated (sadness, happiness, anger, disgust, fear, and surprise). Following experimental testing, their behaviour was rated by two independent teachers on the Psychopathy Screening Device (PSD). The PSD assesses two dimensions of behavioral problems: affective-interpersonal disturbance and impulsive behaviour/conduct problems. The results showed that the ability to recognise sad and fearful expressions (but not happy, angry, disgusted, or surprised expressions) was inversely related to both level of affective-interpersonal disturbance and impulsive/conduct problems. These results are interpreted with reference to current models of empathy and its disorders.     

Defensive emotions and evaluative judgements: Sensitivity to anger and fear predicts moral judgements,whereas sensitivity to disgust predicts aesthetic judgements

Aesthetic and moral evaluations engage appetitive and defensive emotions. While the role played by pleasure in positive aesthetic and moral judgements has been extensively researched, little is known about how defensive emotions influence negative aesthetic and moral judgements. Specifically, it is unknown which defensive emotions such judgements tap into, and whether both kinds of judgement share a common emotional root. Here, we investigated how participants' individual sensitivity to disgust, fear, anger and sadness predicted subjective judgements of aesthetic and moral stimuli. Bayesian modelling revealed that participants who were more sensitive to anger and fear found conventional and moral transgressions more wrong. In contrast, participants who were more sensitive to disgust disliked asymmetrical geometric patterns and untidy rooms more. These findings suggest that aesthetic and moral evaluations engage multiple defensive emotions, not just disgust, and that they may rely on different defensive emotions as part of their computational mechanism.     

A Voxel-based lesion study on facial emotion recognition after circumscribed prefrontal cortex damage

Previous studies have shown inconsistent findings regarding the contribution of the different prefrontal regions in emotion recognition. Moreover, the hemispheric lateralization hypothesis posits that the right hemisphere is dominant for processing all emotions regardless of affective valence, whereas the valence specificity hypothesis posits that the left hemisphere is specialized for processing positive emotions while the right hemisphere is specialized for negative emotions. However, recent findings suggest that the evidence for such lateralization has been less consistent. In this study, we investigated emotion recognition of fear, surprise, happiness, sadness, disgust, and anger in 30 patients with focal prefrontal cortex lesions and 30 control subjects. We also examined the impact of lesion laterality on recognition of the six basic emotions. The results showed that compared to control subjects, the frontal subgroups were impaired in recognition of three negative basic emotions of fear, sadness, and anger – regardless of the lesion laterality. Therefore, our findings did not establish that each hemisphere is specialized for processing specific emotions. Moreover, the voxel-based lesion symptom mapping analysis showed that recognition of fear, sadness, and anger draws on a partially common bilaterally distributed prefrontal network.
