Role Of Fear Research Articles

The role of fear and dopamine-striatal pathways in grooming.

Fear is a fundamental emotion that triggers rapid and automatic behavioral response. Fear is known to suppress reward-seeking behaviors, interrupt previous activities to prioritize defensive responses and lead to rapid switch to defensive reactions. Dopamine (DA) plays a complicated role in the choice and performance of actions and it has a potential interaction of innate actions with the presence of fear. Here, in a series of experiments we explore the role of the different DA striatal pathways in mediating grooming, an innate behavior comprised of a structured sequence of repetitive actions, with or without the presence of fear. Using chemogenetics, we specifically inhibited the DA pathways projecting to the dorsolateral striatum (DLS), dorsomedial striatum (DMS), and ventral striatum (VS), while mice were engaged in a behavioral paradigm inducing grooming during the presentation of a fear related cue. We found that fear related cues consistently reduced grooming proportions and shortened induced grooming bouts, regardless of DA manipulation, indicating prioritization of freezing behavior in fearful contexts. This also suggests that fear responses may be mediated through pathways independent of DA-based action selection. The role of DA, however, varies depending on the specific striatal pathway. Inhibiting DLS DA input delayed grooming initiation and reduced grooming when competing with freezing. In contrast, DMS DA input had no effect on grooming, while inhibition of VS mesolimbic DA input increased grooming proportions and duration. These findings underscore the distinct and sometimes opposing roles of different DA-striatal pathways in modulating innate behaviors. We discuss potential implications of this duality in DA function for both theoretical and clinical fields.

Role of Fear and disease on the Dynamics of two prey-one predator model with extended Holling type II functional response

This paper deals with the studying and modeling the dynamical interaction between two prey where one of the prey species behave stronger than other, and one predator species,. The influence of fear is integrated into the development rate of vulnerable prey species owing to predation, with the spread of a SI illness among robust prey species. Here it is considered that predator both prey according to Holling type II functional response for two prey species. Then the formulation of the model is described and the boundness of solution of the system is discussed. The local stability as well as global stability for each model steady states is analyzed. Finally, with the help of MATLAB program, it is performed numerical simulations to support the evidence of our analytical results. Finally, a brief conclusion on the total work is given.

An Honest Reckoning With the Amygdala and Mental Illness.

Anxiety disorders are a leading source of human misery, morbidity, and premature mortality. Existing treatments are far from curative for many, underscoring the need to clarify the underlying neural mechanisms. Although many brain regions contribute, the amygdala has received the most intense scientific attention. Over the past several decades, this scrutiny has yielded a detailed understanding of amygdala function, but it has failed to produce new clinical assays, biomarkers, or cures. Rising to this urgent public health challenge demands an honest reckoning with the functional-neuroanatomical complexity of the amygdala and a shift from theories anchored on "the amygdala" to models centered on specific amygdala nuclei and cell types. This review begins by examining evidence from studies of rodents, monkeys, and humans for the "canonical model," the idea that the amygdala plays a central role in fear- and anxiety-related states, traits, and disorders. Next, the authors selectively highlight work indicating that the canonical model, while true, is overly simplistic and fails to adequately capture the actual state of the evidentiary record, the breadth of amygdala-associated functions and illnesses, or the complexity of the amygdala's functional architecture. The authors describe the implications of these facts for basic and clinical neuroimaging research. The review concludes with some general recommendations for grappling with the complexity of the amygdala and accelerating efforts to understand and more effectively treat amygdala-related psychopathology.

The role of fear as a barrier and facilitator to antiretroviral therapy initiation in Indonesia: insights from patients and providers

ABSTRACT Initiating antiretroviral therapy (ART) in Indonesia poses major challenges, with limited studies on specific ART initiation barriers and facilitators. Using a socioecological approach, we explored, through semi-structured interviews, the perspectives of 67 participants: 17 people with HIV not (yet) on ART, 30 people with HIV on treatment, and 20 HIV service providers (HSPs). Fears emerged as pervasive barriers to initiation encompassing, at the intrapersonal level, (irrational) fears of negative medical and non-medical consequences. At the health system level, fears were linked to concerns about bureaucracy and insufficient universal coverage. On a societal level, fears stemmed from prevalent myths, misinformation on social media, and the impact of COVID-19. Interestingly, fear also served as a facilitator to initiation. At the intrapersonal level, initiation was driven by a fear of deteriorating health or death due to AIDS-related conditions. At the interpersonal level, buddies and HSPs leveraged to motivate initiation. At the societal level, accurate yet fear-inducing information on social media stimulated initiation. Perspectives differed between people with HIV and HSP, with people with HIV emphasizing barriers on intrapersonal to health system levels, while HSP focused mostly on intrapersonal and interpersonal barriers, albeit recognizing the crucial role of health systems.

Fear and Chameleon Politics in Papua, Indonesia

In this response we critique Cahyo Pamungkas and Yogi Setya Permana's proposal to see military repression in West Papua as a result of two equal factors: fear of Papuan independence and Papuan fear of military repression. They argue this in the article titled "The Role of Fear and Memory in West Papua's Ethnonationalist Conflict," published in this journal in volume 97 (1) in March 2024. While we applaud their effort at investigating the emotional aspects of the West Papua conflict, juxtaposing these two forms of fear to explain the cycle of violence in Indonesia's easternmost region fails to reflect the reality of the situation. In this article we suggest several other paths to develop a deeper comprehension of fear in Papua. Such investigations will also show the need for a shift in the general perspective on the resolution of the Papua conflict.

Exploring panic buying as a situational response – the role of fear, media exposure and context-specific paranoia

PurposeDrawing on prospect theory, terror management theory, and social influence theories, this study explores the phenomenon of panic buying amid the COVID-19 pandemic, namely its situational antecedents such as fear of COVID-19, increased media exposure to COVID-19-related news, and context-specific paranoia. It offers insight into the situational nature of panic buying, contrary to the purely dispositional/trait conceptualization of irrational spending, usually depicted through the phenomenon of compulsive buying.Design/methodology/approachThis is a cross-sectional study. An online questionnaire was used for data collection from 621 Croatian citizens. The questionnaire features a series of validated instruments designed to measure compulsive buying, fear of COVID-19, and context-specific paranoia. The media exposure scale (MES) was also specifically developed and empirically tested for the purpose of this research.FindingsThe results suggest that individuals who exhibited greater fear of COVID-19 while also experiencing increased exposure to COVID-19-related news were more likely to engage in panic buying. This connection has remained significant even after controlling for compulsive buying tendencies, suggesting that panic buying witnessed during the coronavirus pandemic was a situational phenomenon, not strictly dispositional. This establishes the fear of COVID-19 and increased exposure to pandemic-related news content as situational antecedents to panic buying. After controlling for compulsive buying, this paper does not demonstrate a significant connection between context-specific paranoia and panic buying. Furthermore, context-specific paranoia does not mediate the relationship between media exposure to pandemic-related content and panic buying, whereas the fear of COVID-19 significantly mediates the same relationship.Practical implicationsThis study recognizes people's panic behavior amid the COVID-19 pandemic as a byproduct of a situational, reactive process – not a psychopathological one. Furthermore, it recognizes media sensationalism and the audience's impaired capacity for rational spending as major risk factors preceding the event of panic buying.Originality/valueThis study proposes a novel conceptual framework of irrational spending amid crises such as COVID-19 pandemic, introducing the differentiation between the situational nature of the phenomenon (panic buying), thereby separating it from its previous dispositional operationalizations (hoarding, compulsive buying).

The Role of Fear, Sadness, and Anger in Shaping Support for Climate Policies: Evidence from a UK Survey Experiment

The Role of Fear, Sadness, and Anger in Shaping Support for Climate Policies: Evidence from a UK Survey Experiment

Perinatal and neonatal factors and mental disorders in children and adolescents: looking for the contributions of the early environment to common and dissociable aspects of psychopathology.

High rates of co-occurrence of mental disorders have been hypothesized to represent a result of common susceptibility to overall psychopathology. The purpose of this study is to test the hypothesis that commonalities among psychiatric disorders might be partially driven by sharable perinatal and neonatal environmental factors for mental disorders. Participants were 6-14years of age children and their parents. Primary caregivers provided data on perinatal and neonatal information assessed retrospectively (n = 2231). Psychiatric disorders diagnoses were assessed using the Development and Well Being Behavior Assessment (DAWBA). We used bifactor models to disentangle common from dissociable aspects of psychopathology. These models allow modeling psychiatric disorders as the result of a common domain of psychopathology (p-factor) and three dissociable domains (fear, distress, and externalizing symptoms). Associations were tested using linear and tobit regression models. The p-factor was associated with male sex, low socioeconomic status, gestational smoking, gestational drinking, low levels of maternal education and presence of mental disorder in the mother. Associations with specific factors also emerged suggesting some risk factors might also have some role for fear, distress and externalizing factors. Our study supports the hypothesis that overall susceptibility to psychopathology might be partially driven by sharable perinatal and neonatal factors.

Perceptions of professional stakeholders on perpetration prevention programs designed to prevent sexual offending against children

There has been an increasing focus on the development of perpetration prevention programs designed to prevent the onset of sexual offending against children (online and offline). The present study involved a thematic analysis of 20 professional stakeholders in Nova Scotia who participated in a semi-structured interview that occurred prior to the development and implementation of a perpetration prevention program. Results highlighted that stakeholders saw value in a perpetration prevention program aimed at preventing the onset of sexual offending against children. Stakeholders noted that program content should address sexual-based concerns, focus on improving mental health and well-being, and consider the role of trauma. Stakeholders also emphasized the importance of creating a safe therapeutic environment. Several barriers were identified that focused on recruitment challenges, the role of fear and stigma, and the inclusion of diverse clients and facilitators. The importance of leveraging community organizations and supports was also highlighted. Implications of the findings are discussed in relation to perpetration prevention programming.

The Role of Fear and Memory in West Papua's Ethnonationalist Conflict

In the West Papua conflict, fear fuels both Papuan ethnonationalist and Indonesian nationalist sentiment. We argue that this reciprocal fear and memoria passionis plays a significant role in fuelling political violence. On the one hand, it provokes Papuan activists to respond violently to Indonesian military operations. Fear of losing future generations of indigenous Papuans has strengthened their identity as Papuans and encouraged them to join armed movements against Indonesia. On the other hand, fear of West Papuan independence leads the Indonesian military and police to conduct operations against members of the Free Papua Movement and affiliated groups and other activists not in the independence movement. This results in a "reciprocal fear-fuelled nationalism," whereby Indonesian security forces and Papuan separatist activists are drawn into increasing conflict. In this context, fear becomes institutionalized and socially constructed. By understanding the unending violent conflict in Tanah Papua as related to the transfer of emotions across generations, it becomes clear a military operations approach will not be effective in the long term. Non-violent approaches, especially dialogue with separatist groups, will be more effective in breaking the chain of violent memories, resulting in more positive outcomes for conflict resolution in Papua. Learning from negotiations between the government of Indonesia and the Free Aceh Movement in 2005, we support the proposition that dialogue is the best entry point by which to end this prolonged separatist armed conflict.

Molecular pathways underlying sympathetic autonomic overshooting leading to fear and traumatic memories: looking for alternative therapeutic options for post-traumatic stress disorder.

The sympathoadrenal medullary system and the hypothalamic-pituitary-adrenal axis are both activated upon stressful events. The release of catecholamines, such as dopamine, norepinephrine (NE), and epinephrine (EPI), from sympathetic autonomic nerves participate in the adaptive responses to acute stress. Most theories suggest that activation of peripheral β-adrenoceptors (β-ARs) mediates catecholamines-induced memory enhancement. These include direct activation of β-ARs in the vagus nerve, as well as indirect responses to catecholamine-induced glucose changes in the brain. Excessive sympathetic activity is deeply associated with memories experienced during strong emotional stressful conditions, with catecholamines playing relevant roles in fear and traumatic memories consolidation. Recent findings suggest that EPI is implicated in fear and traumatic contextual memories associated with post-traumatic stress disorder (PTSD) by increasing hippocampal gene transcription (e.g., Nr4a) downstream to cAMP response-element protein activation (CREB). Herein, we reviewed the literature focusing on the molecular mechanisms underlying the pathophysiology of memories associated with fear and traumatic experiences to pave new avenues for the treatment of stress and anxiety conditions, such as PTSD.

The Poison Pen: Slavery, Poison, and Fear in the Antebellum Press

ABSTRACT When enslaved people were accused of poisoning enslavers, it was newsworthy throughout the antebellum United States. Part of the broad appeal of such articles was their malleability; as reports of supposed poison plots or arsenic in a planter’s coffee travelled from newspapers in slave states to the pages of Northern publications, the articles morphed in form, purpose, and emotional tone. Southern readers looked to stories about thwarted poison plots to assuage their fears of a similar fate and present a brave united front. Meanwhile, Northern newspapers invited a host of other emotions from their audience, from enjoyment and schadenfreude to sympathy and anger. This article on messaging about slavery, poison, and fear in the antebellum United States builds on my monograph, Mastering Emotions: Feelings, Power, and Slavery in the United States, to focus on the emotional politics of fear. Examining how news about enslaved poisoners circulated and shapeshifted sheds light on the relationship between the antebellum press and collective emotions, and on the role of fear in defenses and critiques of slavery. While the Southern press framed stories about enslaved poisoners to address and manage members of the slaveocracy’s fears, the abolitionist press worked to invoke and amplify that terror.

The Mediating Effect of Psychological Resilience and Coping Style on Fear of Recurrence and Reproductive Concerns in Breast Cancer Patients of Childbearing Age.

Fear of recurrence and reproductive concerns are great public health concerns among breast cancer patients in childbearing age. The purpose of this study was to explore whether psychological resilience and coping styles play mediating roles in fear of recurrence and reproductive concerns among Chinese breast cancer patients in childbearing age. A total of 1267 breast cancer patients of childbearing age completed the questionnaires, including a brief demographic questionnaire survey. The Chinese version of the Fear of Cancer Recurrence Scale and the Chinese version of the Reproductive Concerns Scale were used to assess the fear of recurrence and reproductive concerns, respectively. And the psychological resilience scale and the simple coping style questionnaire were used to evaluate breast cancer patients' psychological resilience and coping style during childbearing age. Mediation analyses were conducted by using PROCESS macro in the SPSS software. Fear of recurrence had both direct and indirect effects on Reproductive Concerns. psychological resilience and coping style were not only independent mediators in the relationship between fear of recurrence and Reproductive Concerns but also chain mediators. The results of the current study highlight the crucial role of early intervention for Reproductive Concerns with a focus on fear of recurrence of breast cancer patients of childbearing age, more especially, on those with poorer psychological resilience and coping style.

Robotic Virtue, Military Ethics Education, and the Need for Proper Storytellers

The introduction of artificial intelligence (AI) challenges much of our traditional understanding of military ethics. What virtues and what sort of ethics education are needed as we move into an ever more AI-driven military reality? In this article we suggest and discuss key virtues that are needed, including the virtue of prudence and the accompanying virtue of good and proper storytelling. We also reflect on the ideal of “explainable AI,” and philosophize about the role of fear in helping us understand what is actually at stake in a military infused with AI-enabled and AI-driven weapons.

The Benevolent Dictator: Love and Masculine Performativity in Stay with Me

This article analyzes the male protagonist of Ayọ̀bámi Adébáyọ̀’s Stay with Me (2017) as an embodiment of the internal contradictions that customary laws and the masculine performativity exert upon Nigerian men. The novel retells Yejide and Akin’s relationship and their struggles to conceive as Akin hides his erectile dysfunction from Yejide and his family. I analyze Akin under Elnathan John’s satiric label of “the benevolent dictator” (2020) exploring how this term engages with the idea of masculinity and male performativity in contemporary Nigeria. For this, I take as a point of departure Patrick K. Uchendu’s study on Nigerian masculinity (2008) and Daniel J. Smith’s notion of “performativity” in Nigerian men (2016). The role of the family in the imposition of customary practices is underlined as essential in Akin progressively becoming a “benevolent dictator”. Akin’s trust in the potential of love and intimacy is measured against the weight of the pressures exerted by the Nigerian family as an institution. In turn, I delve into the role of fear and shame as “prevent[ing] the subject from betraying ‘ideals’” (Ahmed 2014, 106). Ultimately, I claim that the actions of the benevolent dictator in the private sphere echo Adébáyọ̀’s narration of Ibrahim Babangida’s military dictatorship (1985-1993).

Association Between Positive Troponin and Fear of Earthquakes: A Retrospective Study.

Introduction The association between natural disasters and cardiovascular events has been well-established. However, the impact of earthquakes on cardiac health, and the role of fear in this association, remains unclear. This study aims to examine the association between positive troponin levels, indicating cardiac ischemia, and fear of earthquakes among Emergency Roompatients at a referral center in Beirut, Lebanon. Materials and methods This is a retrospective study conducted on patients who presented to the Emergency Room with suspected cardiac symptoms and were ordered a troponin level after the Kahramanmaras earthquakethat occurred on the sixth of February 2023 and affected many neighboring countries, including Lebanon. A control group was taken from the same period in 2022 (January-February) and from the period prior to theearthquake (January up to 6 February 2023). Patients were divided into three groups: the first group (group 1) comprised patients who presented during January and February 2022 (period 1). The second group (group 2) included patients who presented from January up to the sixth of February 2023, when the Kahramanmaras earthquake occurred (period 2). The third group (group 3) consisted of patients who presented after the earthquake until the end of February 2023 (period 3). Patients who consented to participate in the study were sent a questionnaire to assess their Fear of Earthquake Scale (FES), chief complaints, date of presentation to the Emergency Room, past medical history, and other socio-demographic data. Results Our study involved 1410 participants, with 782 belonging to group 1, 470 to group 2, and 158 to group 3. The mean age was 62.96 ± 17.87 for the total population and 63.9 ± 18.49 for patients of group 3. The number of positive troponin results was higher during period 3 (62% of participants) in comparison to period 2 and 1 (22.1% and 28.5% of participantsrespectively) (p<0.001).Positive troponin was significantly more common among patients who are non-smokers (53%, p-value <0.001), with a negative family history of premature cardiac diseases (93.9%, p-value <0.05), previously healthy (46.9%, p-value <0.001) and presenting to the Emergency Room for dyspnea or palpitations (17.3% each, p-value <0.001). In addition, patients who tested positive for troponin had a higher mean FES(27.89 ± 1.23 versus 20.47 ± 6.02) and a higher mean age (71.07 ± 14.33 versus 52.25 ± 18.69) in comparison to those who tested negative for troponin (p-value <0.05). Conclusion This study suggests that fear of earthquakes maybe associated with cardiac ischemia, as indicated by positive troponin levels. Healthcare providers should be aware of the potential impact of natural disasters on cardiovascular health and take measures to address patients' fears and concerns.

Fear of heights shapes postural responses to vibration-induced balance perturbation at virtual height.

Standing upright at height is a challenging situation involving intense threat of balance loss and fall. The ability to maintain balance in such conditions requires properly resolving sensory conflicts and is influenced by fear. To get more insight on the role of fear in balance control at height, we explored the dynamics of postural behavior in the situation of enhanced threat of potential balance loss. In 40 young individuals with varying fear of heights, we combined simulated exposure to height in a virtual reality environment with bilateral vibration of tibialis anterior muscles which evokes posture destabilization (the so-called vibration-induced falling). Under such condition of enhanced postural threat, individuals with intense fear of heights showed stronger stiffening of posture compared with individuals with low fear of heights who react more flexibly and adaptively to posture destabilization. This group difference was evident already at ground level but further increased during virtual height exposure. Our data show that fear of height significantly affects posture adaptation to balance-destabilizing events. Our findings demonstrate that the assessment of postural behavior during threatening situations in the virtual reality environment provides valuable insights into the mechanisms of balance control and may be used to develop novel strategies aimed at prevention of falls.

Role of Fear on Consumers’ Buying Tendencies: Mediating Role of Social Media Usage

The present study empirically examines the impact of fear on consumers’ buying tendencies (Impulse buying, Panic buying and Online purchase intention). The study assesses the role of social media usage as a mediating variable in the above relationship. Also, it investigates the variation in consumer buying tendencies, fear, and social media usage across demographics. A total of 389 survey responses were collected online through a structured questionnaire using a snowball sampling technique from consumers of Delhi, India. A causal relationship established using Structural Equation Modelling reveals linkages of fear with panic buying and social media usage fully mediates this relationship, Further, the link between fear and online purchase is partially mediated by social media usage, and no linkage is found with impulse buying. ANOVA and T-test results show that panic buying tendency is higher in females and married individuals, social media usage is higher in unmarried younger age group people and online purchase intention is practiced more by males in middle- and upper-income groups. The study concludes by providing theoretical and practical implications.

Stratum Griseum Periventriculare-mediated Fear Emotion Regulates Motor Behavior in Pigeons

A pigeon robot is an ideal experimental animal for research in flying animal robots. The majority of current research publications have entailed electrical stimulation of the motor nuclei to regulate movement forcibly, and although a “virtual fear” behavior model has been proposed, the structure, location, and function of the nuclei that generate fear emotions remain obscure. Previous studies have shown that the Stratum Griseum Periventriculare (SGP) of pigeons is homologous to the mammalian periaqueductal gray (PAG), which plays an essential role in mammalian fear. To reveal the role of fear mediated by the SGP in behavioral regulation, we evaluated the structure and location of the SGP by histologic identification combined with magnetic resonance imaging, and analyzed the behavior of the SGP by electrical stimulation. Finally, the function of the SGP was verified with escape testing and homing experiments in an open field. Our results showed that the SGP is located in the pigeon midbrain and divided into two subregions, the dorsal part of the stratum griseum periventriculare (SGPd) and the ventral part of the stratum griseum periventriculare (SGPv) (the ranges were AP1.5–4.75 mm, ML1.75–6.75 mm, and DV2.2–7.1 mm), and that wired and wireless electrical stimulation freezing was the dominant behavior. In the escape test, SGP electrical stimulation caused the pigeons to flee to a safe place, while in the open-field homing test, electrical stimulation of the SGP induced evasive behavior in pigeons away from their original homing route. These results confirm that the SGP plays a crucial role in fear, and that electrical stimulation of this nucleus induces corresponding fear behaviors.
