"Even in a Place of Sorrow, Even in a Place of Joy": Intersections of Blackness and Southernness in the Works of bell hooks and Honorée Fanonne Jeffers

ABSTRACT: bell hooks's Belonging: A Culture of Place (2009) and Honorée Fanonne Jeffers's The Love Songs of W. E. B. Du Bois (2021) exist at the intersection of southernness and Blackness, mapping the ways that the south can be a site of trauma and profound identification for the Black southerners who call it home. Both texts articulate the intense emotional experience that stems from returning to the south and offer alternative models for considering Black southern affects. These models challenge the white emotional paradigm—particularly its preoccupation with nostalgia—that dominates conversations about southern feelings. Situating these two texts within the current discourse surrounding monuments and memorials, this article highlights a non-linear engagement with history that prioritizes the felt aftermaths of slavery and the Jim Crow era in southern Black communities. In centering the complex, and often contradictory, affects that define the Black southern experience, both Belonging and The Love Songs of W. E. B. Du Bois articulate the felt forms through which Black southerners return to both the physical region and history of the south.

A neurophysiological signature of dynamic emotion recognition associated with social communication skills and cortical gamma-aminobutyric acid levels in children.

Emotion recognition is a core feature of social perception. In particular, perception of dynamic facial emotional expressions is a major feature of the third visual pathway. However, the classical N170 visual evoked signal does not provide a pure correlate of such processing. Indeed, independent component analysis has demonstrated that the N170 component is already active at the time of the P100, and is therefore distorted by early components. Here we implemented, a dynamic face emotional paradigm to isolate a more pure face expression selective N170. We searched for a neural correlate of perception of dynamic facial emotional expressions, by starting with a face baseline from which a facial expression evolved. This allowed for a specific facial expression contrast signal which we aimed to relate with social communication abilities and cortical gamma-aminobutyric acid (GABA) levels. We recorded event-related potentials (ERPs) and Magnetic Resonance (MRS) measures in 35 typically developing (TD) children, (10-16 years) sex-matched, during emotion recognition of an avatar morphing/unmorphing from neutral to happy/sad expressions. This task allowed for the elimination of the contribution low-level visual components, in particular the P100, by morphing baseline isoluminant neutral faces into specific expressions, isolating dynamic emotion recognition. Therefore, it was possible to isolate a dynamic face sensitive N170 devoid of interactions with earlier components. We found delayed N170 and P300, with a hysteresis type of dependence on stimulus trajectory (morphing/unmorphing), with hemispheric lateralization. The delayed N170 is generated by an extrastriate source, which can be related to the third visual pathway specialized in biological motion processing. GABA levels in visual cortex were related with N170 amplitude and latency and predictive of worse social communication performance (SCQ scores). N170 latencies reflected delayed processing speed of emotional expressions and related to worse social communication scores. In sum, we found a specific N170 electrophysiological signature of dynamic face processing related to social communication abilities and cortical GABA levels. These findings have potential clinical significance supporting the hypothesis of a spectrum of social communication abilities and the identification of a specific face-expression sensitive N170 which can potentially be used in the development of diagnostic and intervention tools.

Can psychopathy be prevented? Clinical, neuroimaging, and genetic data: an exploratory study

ABSTRACT The aim of the study was to explore the relationship among brain functional activations elicited by an emotional paradigm, clinical scores (PTSD, anxiety, and depression), psychopathic traits, and genetic characteristics (5-HTTLPR) in a group of severely maltreated children compared to a healthy control group before and after the implementation of a Trauma Focused-Cognitive Behavioral Therapy. The final sample consisted of an experimental group of 14 maltreated children (mean age = 8.77 years old, S.D. = 1.83) recruited from a non-governmental shelter in Mexico City for children who had experienced child abuse and a control group of 10 children from the general population (mean age = 9.57 years old, S.D. = 1.91). Both groups were matched according to age and gender and were assessed before and after the implementation of the aforementioned therapy by means of clinical scales and an emotional paradigm that elicited brain activations which were recorded through functional magnetic resonance imaging. Genotyping of the 5-HTTLPR polymorphism was made at first assessment. A region of interest analysis showed amygdala hyperactivation during exposure to fear and anger stimuli in the maltreated children before treatment. Following therapy, a decrease in brain activity as well as a decrease in clinical symptoms were also observed. 5-HTTLPR polymorphism did not show any effect on the severity of clinical symptoms in maltreated children. Trauma-Focused Behavioral Therapy may help reorganize the brain’s processing of emotional stimuli. These observations reveal the importance of an early intervention when the mechanisms of neuroplasticity may be still recruited.

Neurocognitive Impairment in Non-Central Nervous System Cancer Survivors

Abstract: Cancer and its treatments entail a profound inflammatory response of the central nervous system (CNS). This intense neurotoxic process can lead to significant neurocognitive impairment even in non-CNS cancers. Few studies have examined this domain, and data available is based on limited designs using neuropsychological assessments comprising self-report or traditional testing batteries that capture basic response data. Here, we leverage cognitive electrophysiology, specifically Event-Related Potentials (ERPs), to examine and delineate neurocognitive impairments in non-CNS cancer survivors. Eleven survivors, who were on average 4.6 years in remission from head and neck cancer and 10 matched healthy controls underwent standardized cognitive and emotional “Go-Nogo” paradigms concomitant to EEG recording. Significant differences in amplitude morphology in the very early ERP components (C1, N1, P1) and middle ERP component (N2), were apparent between non-CNS cancer survivors and controls. Later ERP components (P3, N4) did not show amplitude differences. Non-CNS cancer survivors yielded faster latencies in the early components for pain-related stimuli during the emotional paradigm, albeit tended to yield slower ERP latencies overall across both experiments. These findings suggest that early gating and inhibitory control are dysregulated in non-CNS cancer survivors, which can impact executive functioning and cognitive processing involved in everyday activities for many years post-treatment. The findings do not fully align with ERP morphologies associated with neurocognitive impairment in degenerative conditions (such as dementia and Alzheimer’s disease), affecting later-stage ERP components. Our initial results suggest that (1) cognitive impairments in cancer survivors do not follow a degenerative trajectory, (2) rather are in line with “lesion” related damage (such as stroke, epilepsy), and as such, (3) have the potential for treatments involving neurocognitive plasticity.

Association between Mood and Sensation Seeking Following rTMS.

Previous studies investigating mood changes in healthy subjects after prefrontal repetitive transcranial magnetic stimulation (rTMS) have shown largely inconsistent results. This may be due to methodological issues, considerable inter-individual variation in prefrontal connectivity or other factors, e.g., personality traits. This pilot study investigates whether mood changes after rTMS are affected by personality parameters. In a randomized cross-over design, 17 healthy volunteers received three sessions of 1 Hz rTMS to Fz, F3 and T3 (10/20 system). The T3 electrode site served as the control condition with the coil angled 45° to the scalp. Subjective mood was rated at baseline and after each condition. Personality traits were assessed using the NEO Five-Factor Inventory (NEO-FFI) and the Sensation Seeking Scale (SSS). For all conditions, a significant association between mood changes towards a deterioration in mood and SSS scores was observed. There were no differences between conditions and no correlations between mood changes and NEO-FFI. The data show that sensation-seeking personality has an impact on subjective mood changes following prefrontal rTMS in all conditions. Future studies investigating the effects of rTMS on emotional paradigms should include individual measures of sensation-seeking personality. The pre-selection of subjects according to personality criteria may reduce the variability in results.

A Study of Emotional Paradigm in Kunzang Choden’s Folktales of Bhutan

This research examines the emotional paradigm in Kunzang Chode’s Folktales of Bhutan to bring about self- realization of the impacts of positive and negative emotions. The poetic and imaginative essence of folktales reflects the need for a plural consciousness as it is only through a plural consciousness that their perspectives, belief systems and experiential grids can be comprehended. Folktales and folklore have been transmitted orally for generations to date. These folktales and folklore are important media to transmit and communicate social, cultural, ethical, and spiritual values across the globe. In Bhutan, these tales have been a source of entertainment. Although the tradition of the narration is slowly diminishing in modern times, the trend is still alive, particularly in the rural regions of the country. Bhutanese folktales revolve mostly around Buddhist philosophy on values and virtues of righteousness. Choden’s Folktales of Bhutan portrays the various forms of emotion that every individual experience in their day to day lives. The research adopts the psychoanalysis theories to explore all these aspects of emotions through a mixed-mode method.

The influence of bilingual experience on executive function under emotional interference: Evidence from the N1 component.

The influence of bilingual education and experience on an individual's information-processing ability has recently been a hot issue in international studies. Previous studies have found that bilingual experience affects executive function, but the results remain controversial. Executive function refers to the conscious control of purposeful behavior. It is responsible for processing high-level action controls, including such sub-functions as inhibitory control, cognitive switching, and working memory updating. Emotion, as an essential factor in daily life, also has a complex interaction with executive function. This paper explores whether the bilingual cognitive advantage effect can continue in the more complex conditions of emotional interference. To investigate the specific electrophysiological characteristics of the participants at different stages of cognitive processing, we used a combination of the behavioral and ERP experiments in which the positive, neutral, and negative emotional stimuli were selected as emotional interference conditions and the emotional Simon paradigm, the cognitive switching of emotion paradigm, and the emotional N-back paradigm was adopted. The results show that the main effect of the N1 component amplitude is significant. Specifically, the amplitude of the N1 component in the proficient bilinguals is significantly smaller than that of the non-proficient bilinguals, while the main effects of other component groups are not significant, indicating that under the condition of emotional interference, the influence of bilingual experience on executive function only exists in the early attention stage and that the bilingual experience can improve the individual's attentional control and speed up attention processing in the early attention stage.

Continuum of Fuzzy Emotions

The article deals with the current trends in the field of linguistic categorization of emotions. The emotional spectrum is much wider than the experiences that possess stable verbal explications. Fuzzy emotions include mixed, blended, complex, and other emotional experiences. They are primary, but they have never been subjected to independent linguistic research. This article focuses on the cultural particularities of emotions that reflect the ability of language consciousness to actualize the boundless emotional and semantic potential of the word to express the inner world. The research relied on the National Corpus of the Russian language to describe the process of creating emotional endoconcepts, i.e., emotional experiences that go beyond the traditional classification of emotive words. The authors believe that the controversial nature of the basic emotional paradigm is argued by the class of emotive words formed from basic emotions, e.g., sad emotions. Their dominant remains fuzzy, and only the evaluative meaning is clear. The approach that the linguistics of emotions adopts to categorize emotive words has a number of advantages because it takes into account the poly-ambivalence, discursivity, and flexibility of emotions that depend on the communicative situation.

Emotion Ontology Studies: A Framework for Expressing Feelings Digitally and its Application to Sentiment Analysis

Emotion ontologies have been developed to capture affect, a concept that encompasses discrete emotions and feelings, especially for research on sentiment analysis, which analyzes a customer's attitude towards a company or a product. However, there have been limited efforts to adapt and employ these ontologies. This research surveys and synthesizes emotion ontology studies to develop aFramework of Emotion Ontologiesthat can be used to help a user select or design an appropriate emotion ontology to support sentiment analysis and increase the user's understanding of the roles of affect, context, and behavioral information with respect to sentiment. The framework, which is derived from research on emotion ontologies, psychology, and sentiment analysis, classifies emotion ontologies as discrete emotion or one of two hybrid ontologies that are combinations of the discrete, dimensional, or componential process emotion paradigms. To illustrate its usefulness, the framework is applied to the development of an emotion ontology for a sentiment analysis application.

Narrative Insights Reveal the Motivations of Young Agricultural Entrepreneurs in Laos

The participation of youth in agricultural entrepreneurship (agripreneurship) is beneficial for the sustainable development of agrarian societies that are transitioning towards the commercialization of agriculture. Accordingly, we investigated the phenomena that motivate practicing young, small- and medium-scale agripreneurs to pursue their careers, using the Lao People’s Democratic Republic (Laos) as a case study. To achieve this, we applied narrative inquiry techniques to the accounts of 74 young Laotian agripreneurs regarding their entry into agripreneurship. This enabled us to identify and describe common and influential paradigms that were subsequently interpreted from the perspective of entrepreneurship and behavioral studies of career decision making to explain the influence of motivations on the young agripreneurs. Our study has shown that despite the characteristics that set agripreneurship in Laos apart from entrepreneurship in general, commonly identified typologies of entrepreneurial motivation, particularly income, extrinsic benefits and emotional paradigms also motivate Lao youth to become agripreneurs. The application of narrative inquiry has revealed the emphasis some practicing agripreneurs in Laos place on the attainability of their career, which resulted in its practice by both opportunity-driven and necessity-driven entrepreneurs, with implications for the sustainable development of other countries in transition to commercial agriculture.

Brain activity changes with emotional words in different stages of psychosis.

To date, a large number of functional magnetic resonance imaging (fMRI) studies have been conducted on psychosis. However, little is known about changes in brain functioning in psychotic patients using an emotional auditory paradigm at different stages of the disease. Such knowledge is important for advancing our understanding of the disorder and thus creating more targeted interventions. This study aimed to investigate whether individuals with first-episode psychosis (FEP) and chronic schizophrenia show abnormal brain responses to emotional auditory processing and to compare the responses between FEP and chronic schizophrenia. Patients with FEP (n = 31) or chronic schizophrenia (n = 23) and healthy controls (HCs, n = 31) underwent an fMRI scan while presented with both emotional and nonemotional words. Using HC as a reference, patients with FEP showed decreased right temporal activation, while patients with chronic schizophrenia showed increased bilateral temporal activation. When comparing the patient groups, individuals with FEP showed lower frontal lobe activation. To the best of our knowledge, this is the first study with an emotional auditory paradigm used in psychotic patients at different stages of the disease. Our results suggested that the temporal lobe might be a key issue in the physiopathology of psychosis, although abnormal activation could also be derived from a connectivity problem. There is lower activation in the early stage and evolution to greater activation when patients become chronic. This study highlights the relevance of using emotional paradigms to better understand brain activation at different stages of psychosis.

The effects of hypnotherapy compared to cognitive behavioral therapy in depression: a NIRS-study using an emotional gait paradigm

Hypnotherapy (HT) is a promising approach to treating depression, but so far, no data are available on the neuronal mechanisms of functional reorganization after HT for depressed patients. Here, 75 patients with mild to moderate depression, who received either HT or Cognitive Behavioral Therapy (CBT), were measured before and after therapy using functional near-infrared spectroscopy. We investigated the patients’ cerebral activation during an emotional human gait paradigm. Further, rumination was included as predictor. Our results showed a decrease of functional connectivity (FC) between two regions that are crucial to emotional processing, the Extrastriate Body Area (EBA) and the Superior Temporal Sulcus (STS). This FC decrease was traced back to an activation change throughout therapy in the right STS, not the EBA and was only found in the HT group, depending on rumination: less ruminating HT patients showed a decrease in right STS activation, while highly ruminating patients showed an increase. We carefully propose that this activation change is due to the promotion of emotional experiences during HT, while in CBT a focus lay on activating behavior and changing negative cognitions. HT seemed to have had differential effects on the patients, depending on their rumination style: The increase of right STS activation in highly ruminating patients might mirror the improvement of impaired emotional processing, whilst the decrease of activation in low ruminating patients might reflect a dismissal of an over-compensation, associated with a hyperactivity before therapy. We conclude that HT affects emotional processing and this effect is moderated by rumination.

Impairment of recognition of facial expressions in different types of dementia

AbstractBackgroundImpairment of facial expression recognition in dementia is one of the cognitive deficits that could affect the social life of dementia patients. The severity of the facial expression recognition in different types of dementia has not been fully addressed. Previous studies showed that EEG event‐related oscillation (ERO) studies could reveal the brain dynamics during successful facial expression recognition. Furthermore, the impairment of facial recognition in Alzheimer's disease patients were represented with abnormal EROs (Güntekin et al., 2019). The present study aims to compare the impaired facial expression recognition between different types of dementia by analysis of event‐related delta responses. The role of delta responses in facial expression and emotional paradigms was reported previously by several researchers (Güntekin and Başar, 2014).Method25 Healthy elderly controls (HC), 25 Mild Cognitive Impairment patients (MCI), 25 patients with Alzheimer's disease (AD), 15 patients with Parkinson's disease with Mild Cognitive Impairment (PDMCI) and 16 patients with Parkinson's disease Dementia (PDD) were included in the study. The electroencephalographic activity was recorded during the perception of the facial expression recognition task (Angry, Happy, Neutral). Delta power and phase‐locking were computed for each facial recognition stimuli and compared among the groups (ANOVA, p<0.05).ResultBoth delta power and delta phase locking were lower in dementia groups than healthy controls being worst in PDD. Figure 1 shows the grand average of delta power in all groups for the right occipital location. PDD (p<0.0001) and AD (p<0.05) had lower delta power than the healthy controls, the reduction of delta responses in PDD and AD were especially found over occipital locations. MCI and PDMCI subjects were found less impaired facial expression recognition compared to AD and PDMCI.ConclusionThe present study showed that dementia patients had severe facial recognition deficits that increased cognitive impairment. Event‐related delta responses successfully showed the impaired recognition of facial expression in different types of dementia groups. Among all dementia subjects, PDD patients had the most reduced delta responses that could be an electrophysiological biomarker of impaired facial expression recognition.

Similarities and divergences between emotional hearing – emotional retrieval and emotional sensitivity paradigms

The present article focuses on highlighting the theoretical aspects of the topic and the interest shown towards the novelty and infl uence of these concepts – emotional hearing, emotional retrieval and emotional sensitivity, taking into account the peculiarities of each. The psychological research of many scholars have shown that appropriate perception of the emotional state of the speaker’s voice is an important component of man’s relationship with the world around him. The greater the lability of the emotional system, the higher the relationship of emotional hearing with emotional retrieval and emotional sensitivity, and the understanding that they are dependent on emotional susceptibility, which occurs in the forms of emotional reaction, emotional rigidity, and emotional resilience, which depend on the person’s interests, beliefs, goals, relationships, spiritual will.

The emotional adaptation aftereffect discriminates between individuals with high and low levels of depressive symptoms

ABSTRACT The adaptation aftereffect plays a critical role in human development and survival. Existing studies have found that, compared with general individuals, individuals with learning disability, autism and dyslexia show a smaller amount of non-affective-based cognitive adaptation aftereffect. Nevertheless, it is unclear whether individuals with depression or depression tendency show similar phenomenon in the adaptation aftereffect, and whether such depression tendency occurs in the non-affective-based cognitive or emotional adaptation aftereffect. To address this question, the present study conducted two experiments. Experiments 1A and 1B used the emotional facial expression adaptation paradigm to examine whether Chinese participants showed the emotional adaptation aftereffect and whether the emotional adaptation aftereffect was influenced by physical features of faces, respectively. Experiment 2 recruited two groups of participants, with high and low depression, respectively, to examine whether they showed differences in the emotional or cognitive adaptation aftereffect. Results showed that Chinese participants showed the typical emotional adaptation aftereffect, which was not influenced by physical features of faces. More importantly, compared to the low-depression group, the high-depression group showed a smaller emotional adaptation aftereffect, but the two groups showed a similar cognitive adaptation aftereffect. These results suggest that level of depressive symptoms is associated with the emotional adaptation aftereffect.

The age-related positivity effect: forgetting the negative and/or remembering the positive? An inter-task study.

A growing number of studies have shown that when compared to younger adults, older adults are better at recalling positive information than negative information. However, it is not yet clear whether this age-related positivity effect relies on a greater ability to recall positive information or on a decreased ability to recall negative information. We therefore aimed to study the specific mechanisms underlying the age-related positivity effect using different memory tasks. We used an emotional word memory paradigm including immediate free recall, recognition, and delayed free recall tasks. Forty-five young adults (m = 20.0 years) and 45 older adults (m = 69.2 years) participated, all of whom were native French speakers. Thirty-six French low-arousal words (12 positve, 12, negative, 12 neutral) were selected from an emotional lexical database (Gobin et al. 2017) and divided into three equal groups of positive, neutral and negative terms. For the recognition task, 36 new words were selected. The results show that the age-related positivity effect specifically depended on a decrease in negativity preference (i.e., the comparison between negative and neutral words) in older adults, in comparison with younger adults, both in the immediate and delayed free recall tasks. In these tasks, younger adults recalled more negative than neutral words, whereas there was no difference in older adults. During the recognition task, no age-related positivity effect was observed. The results also show that, for the immediate recall task, the greater the memory ability of older adults, the lower their negativity preference. This correlation was not significant in the delayed recall task. These results suggest that, when compared with younger adults, older adults disengage from processing negative words that require costly cognitive processes. A low negativity preference indicates that memory abilities are well-maintained. The results are discussed within the framework of socio-emotional selectivity theory.

Epigenetic Mediation of AKT1 rs1130233's Effect on Delta-9-Tetrahydrocannabinol-Induced Medial Temporal Function during Fear Processing.

High doses of delta-9-tetrahydrocannabinol (THC), the main psychoactive component of cannabis, have been shown to have anxiogenic effects. Additionally, THC effects have been shown to be modulated by genotype, including the single nucleotide polymorphism (SNP) rs1130233 at the protein kinase AKT1 gene, a key component of the dopamine signalling cascade. As such, it is likely that epigenetic methylation around this SNP may affect AKT gene expression, which may in turn impact on the acute effects of THC on brain function. We investigated the genetic (AKT1 rs1130233) and epigenetic modulation of brain function during fear processing in a 2-session, double-blind, cross-over, randomized placebo-controlled THC administration, in 36 healthy males. Fear processing was assessed using an emotion (fear processing) paradigm, under functional magnetic resonance imaging (fMRI). Complete genetic and fMRI data were available for 34 participants. THC caused an increase in anxiety and transient psychotomimetic symptoms and para-hippocampal gyrus/amygdala activation. Number of A alleles at the AKT1 rs1130233 SNP, and percentage methylation at the CpG11–12 site, were independently associated with a greater effect of THC on activation in a network of brain regions including left and right parahippocampal gyri, respectively. AKT1 rs1130233 moderation of the THC effect on left parahippocampal activation persisted after covarying for methylation percentage, and was partially mediated in sections of the left parahippocampal gyrus/hippocampus by methylation percentage. These results may offer an example of how genetic and epigenetic variations influence the psychotomimetic and neurofunctional effects of THC.

Adolescent girls’ physiological reactivity to real-world peer feedback: A pilot study to validate a Peer Expressed Emotion task

Peer feedback becomes highly salient during adolescence, especially for girls. The way in which adolescents react to social feedback is associated with psychosocial adjustment and mental health. Consequently, researchers are increasingly interested in understanding the physiological and neural underpinnings of adolescent response to feedback by simulating the experience of rejection and acceptance using computer-based paradigms. However, these paradigms typically use nonfamiliar peers and the facade of internet chatrooms or games to present artificial peer feedback. The current study piloted the use of a novel and potentially more ecologically valid peer expressed emotion paradigm in which participants listen to prerecorded clips of ostensible personalized feedback made by their close friend. Physiological data measuring autonomic nervous system response were collected as an index of emotional reactivity/arousal and cognitive-affective processing. Results show promising preliminary evidence validating the task for future use. Participants (N = 18 girls, aged 11–17 years) reported feeling more positive following praise, relative to critical and neutral feedback, and reported feeling more upset following criticism, relative to praise and neutral feedback. Girls exhibited greater pupillary dilation, skin conductance levels (N = 17), and/or heart rate (N = 17) while listening to affectively charged, peer feedback compared with neutral yet personally relevant statements. Girls also exhibited variable physiological response when listening to praising versus critical feedback. Findings from this pilot study validate the use of this novel Peer Expressed Emotion task for the investigation of adolescents’ emotional and physiological reactivity in response to real-world peer evaluation. However, it is important to recognize that this study provides only preliminary findings and that future research is needed to replicate the results in larger samples.

Suppressing negative materials for remitted depressed individuals: Substitution forgetting and incidental forgetting strategies

Intentional forgetting is significantly effective for forgetting unwanted non-emotional material. However, whether the suppressive effect of unaided suppression differs from that of substitution forgetting when applied to negative materials by remitted depressed individuals is unclear. A modified think/no-think (TNT) emotional paradigm including specific strategies (unaided suppression, positive-word substitution, and positive-picture substitution) was used with 84 remitted depressed individuals and 80 controls. The participants in both groups forgot more negative words in the substitution condition than in the unaided condition. The remitted participants forgot more with positive-picture substitution than with positive-word substitution, while the controls showed no difference. Moreover, the participants in both groups forgot more with 0 cue presentations (incidental forgetting) than under any other experimental condition. These results indicate that unaided suppression of negative material in the TNT paradigm shows little suppressive effect. Incidental forgetting and positive-picture substitution forgetting may be better strategies for remitted depressed individuals to forget negative materials.

Audio Features for Music Emotion Recognition: A Survey

The design of meaningful audio features is a key need to advance the state-of-the-art in music emotion recognition (MER). This article presents a survey on the existing emotionally-relevant computational audio features, supported by the music psychology literature on the relations between eight musical dimensions (melody, harmony, rhythm, dynamics, tone color, expressivity, texture and form) and specific emotions. Based on this review, current gaps and needs are identified and strategies for future research on feature engineering for MER are proposed, namely ideas for computational audio features that capture elements of musical form, texture and expressivity that should be further researched. Previous MER surveys offered broad reviews, covering topics such as emotion paradigms, approaches for the collection of ground-truth data, types of MER problems and overviewing different MER systems. On the contrary, our approach is to offer a deep and specific review on one key MER problem: the design of emotionally-relevant audio features.
