Mathematical modeling of the COVID-19 epidemic with fear impact
AIMS Mathematics, 2023 Many studies have shown that faced with an epidemic, the effect of fear on human behavior can reduce the number of new cases. In this work, we consider an SIS-B compartmental model with fear and treatment effects considering that the disease is ...

The effect of disgust and fear modeling on children’s disgust and fear for animals. [PDF]
Journal of Abnormal Psychology, 2014 Disgust is a protective emotion associated with certain types of animal fears. Given that a primary function of disgust is to protect against harm, increasing children's disgust-related beliefs for animals may affect how threatening they think animals are and their avoidance of them.

Differential effects of prior stress on conditioned inhibition of fear and fear extinction [PDF]
Behavioural Brain Research, 2020 Resistant and generalized fear are hallmark symptoms of Post-Traumatic Stress Disorder (PTSD). Given PTSD is highly comorbid with addiction disorders indicates a maladaptive interaction between fear and reward circuits. To investigate learning processes underlying fear, reward and safety, we trained male rats to discriminate among a fear cue paired ...

Fear effect in a three-species food chain model with generalist predator
Mathematical Biosciences and EngineeringWithin the framework of a food web, the foraging behavior of meso-carnivorous species is influenced by fear responses elicited by higher trophic level species, consequently diminishing the fecundity of these species. In this study, we investigate a three-

Influence of fear effect on a Holling type III prey-predator system with the prey refuge
AIMS Mathematics, 2022 The aim of the paper is to study the impact of anti-predator behavior caused by dread of predator species in a prey predator system with Holling III type functional response and prey shelters.

A time-delayed predator-prey model with fear effect and stage structure
Xi'an Gongcheng Daxue xuebao, 2021 The stability of a predator-prey model with two-stage structure and fear effect was studied. This model incorporated maturation time delay of the prey, and a delay differential equation model was established.

Fear information and social phobic beliefs in children: a prospective paradigm and preliminary results [PDF]
, 2002 This paper presents a first attempt to develop a prospective paradigm to test Rachman’s (Behav. Res. Ther. 15 (1977) 375) theory of fear acquisition for social fears. Following the prospective paradigm for animal fears developed by Field et al.

Mathematics, 2023 In this paper, we establish and study a novel predator–prey model that incorporates: (i) the migration of prey between breeding and non-breeding regions; (ii) the refuge effect of prey; and (iii) the reduction in prey pulse birth rate, in the form of a ...

Effects of sleep on memory for conditioned fear and fear extinction. [PDF]
Psychological Bulletin, 2015 Learning and memory for extinction of conditioned fear is a basic mammalian mechanism for regulating negative emotion. Sleep promotes both the consolidation of memory and the regulation of emotion. Sleep can influence consolidation and modification of memories associated with both fear and its extinction.
