Learned Helplessness
Learned helplessness is the behavior exhibited by a subject after enduring repeated aversive stimuli beyond their control. It was initially thought to be caused by the subject's acceptance of their powerlessness, by way of their discontinuing attempts to escape or avoid the aversive stimulus, even when such alternatives are unambiguously presented. Upon exhibiting such behavior, the subject was said to have acquired learned helplessness. Over the past few decades, neuroscience has provided insight into learned helplessness and shown that the original theory was the wrong way about—the brain's default state is to assume that control is not present. The presence of control is therefore learned. However, it is unlearned when a subject is faced with prolonged aversive stimulation. In humans, learned helplessness is related to the concept of self-efficacy, the individual's belief in their innate ability to achieve goals. Learned helplessness theory is the view that clinical depress ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aversive Stimuli
In psychology, aversives are unpleasant stimuli that induce changes in behavior via negative reinforcement or positive punishment. By applying an aversive immediately before or after a behavior, the likelihood of the target behavior occurring in the future may be reduced. Aversives can vary from being slightly unpleasant or irritating to physically, psychologically and/or emotionally damaging. Types of stimuli There are two types of aversive stimuli: Unconditioned Unconditioned aversive stimuli naturally result in pain or discomfort and are often associated with biologically harmful or damaging substances or events. Examples include extreme heat or cold, bitter flavors, electric shocks, loud noises and pain. Aversives can be applied naturally (such as touching a hot stove) or in a contrived manner (such as during torture or behavior modification). Conditioned A conditioned aversive stimulus is an initially neutral stimulus that becomes aversive after repeated pairing with ...

Serotonin
Serotonin (), also known as 5-hydroxytryptamine (5-HT), is a monoamine neurotransmitter with a wide range of functions in both the central nervous system (CNS) and also peripheral tissues. It is involved in mood, cognition, reward, learning, memory, and physiological processes such as vomiting and vasoconstriction. In the CNS, serotonin regulates mood, appetite, and sleep. Most of the body's serotonin—about 90%—is synthesized in the gastrointestinal tract by enterochromaffin cells, where it regulates intestinal movements. It is also produced in smaller amounts in the brainstem's raphe nuclei, the skin's Merkel cells, pulmonary neuroendocrine cells, and taste receptor cells of the tongue. Once secreted, serotonin is taken up by platelets in the blood, which release it during clotting to promote vasoconstriction and platelet aggregation. Around 8% of the body's serotonin is stored in platelets, and 1–2% is found in the CNS. Serotonin acts as both a vasoconstrictor and vas ...

Stockholm Syndrome
Stockholm syndrome is a proposed condition or theory that tries to explain why hostages sometimes develop a psychological bond with their captors. Emotional bonds can possibly form between captors and captives, during intimate time together, but these are considered irrational by some in light of the danger or risk endured by the victims. Stockholm syndrome has never been included in the '' Diagnostic and Statistical Manual of Mental Disorders'' (''DSM''), the standard tool for diagnosis of psychiatric illnesses and disorders in the United States, mainly due to the lack of a consistent body of academic research and doubts about the legitimacy of the condition. History Stockholm bank robbery In 1973, Jan-Erik Olsson, a convict on parole, took four employees (three women and one man) hostage during a failed bank robbery of Kreditbanken, one of the largest banks in Stockholm, Sweden. He negotiated the release from prison of his friend Clark Olofsson to assist him. They held ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Traumatic Bonding
Trauma bonds (also referred to as traumatic bonds) are emotional bonds that arise from a cyclical pattern of abuse. A trauma bond occurs in an abusive relationship, wherein the victim forms an emotional bond with the perpetrator. The concept was developed by psychologists Donald Dutton and Susan Painter. The two main factors that contribute to the establishment of a trauma bond are a power imbalance and intermittent reward and punishment. Trauma bonding can occur within romantic relationships, platonic friendships, parent-child relationships, incestuous relationships, cults, hostage situations, sex trafficking (especially that of minors), hazing or tours of duty among military personnel. Trauma bonds are based on terror, dominance, and unpredictability. As the trauma bond between an abuser and a victim strengthens, it can lead to cyclical patterns of conflicting emotions. Frequently, victims in trauma bonds do not have agency, autonomy, or an individual sense of self. Their ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psychological Abuse
Psychological abuse, often known as emotional abuse or mental abuse, is a form of abuse characterized by a person subjecting or exposing another person to a behavior that may result in psychological trauma, including Anxiety disorder, anxiety, chronic depression, clinical depression or post-traumatic stress disorder amongst other psychological problems. It is often associated with situations of abusive power and control, power imbalance in abusive relationships, and may include bullying, gaslighting, Workplace bullying, abuse in the workplace, amongst other behaviors that may cause an individual to feel unsafe. It also may be perpetrated by persons conducting torture, other violence, acute or prolonged human rights abuse, particularly without legal redress such as detention without trial, false accusations, false convictions, and extreme defamation such as where perpetrated by state and media.

Immune Systems
The immune system is a network of biological systems that protects an organism from diseases. It detects and responds to a wide variety of pathogens, from viruses to bacteria, as well as cancer cells, parasitic worms, and also objects such as wood splinters, distinguishing them from the organism's own healthy tissue. Many species have two major subsystems of the immune system. The innate immune system provides a preconfigured response to broad groups of situations and stimuli. The adaptive immune system provides a tailored response to each stimulus by learning to recognize molecules it has previously encountered. Both use molecules and cells to perform their functions. Nearly all organisms have some kind of immune system. Bacteria have a rudimentary immune system in the form of enzymes that protect against viral infections. Other basic immune mechanisms evolved in ancient plants and animals and remain in their modern descendants. These mechanisms include phagocytosis, antim ...

Cognitive Restructuring
Cognitive restructuring (CR) is a psychotherapeutic process of learning to identify and dispute irrational or maladaptive thoughts known as cognitive distortions,Gladding, Samuel. Counseling: A Comprehensive Review. 6th. Columbus: Pearson Education Inc., 2009. such as all-or-nothing thinking (splitting), magical thinking, overgeneralization, magnification, and emotional reasoning, which are commonly associated with many mental health disorders. CR employs many strategies, such as Socratic questioning, thought recording, and guided imagery, and is used in many types of therapies, including cognitive behavioral therapy (CBT) and rational emotive behaviour therapy (REBT). A number of studies demonstrate considerable efficacy in using CR-based therapies. Overview Cognitive restructuring involves four steps: # Identification of problematic cognitions known as "automatic thoughts" (ATs) which are dysfunctional or negative views of the self, world, or future based upon already existi ...

Major Depressive Disorder
Major depressive disorder (MDD), also known as clinical depression, is a mental disorder characterized by at least two weeks of pervasive depression (mood), low mood, low self-esteem, and anhedonia, loss of interest or pleasure in normally enjoyable activities. Introduced by a group of US clinicians in the mid-1970s, the term was adopted by the American Psychiatric Association for this syndrome, symptom cluster under mood disorders in the 1980 version of the ''Diagnostic and Statistical Manual of Mental Disorders'' (DSM-III), and has become widely used since. The disorder causes the second-most years lived with disability, after low back pain, lower back pain. The diagnosis of major depressive disorder is based on the person's reported experiences, behavior reported by family or friends, and a mental status examination. There is no laboratory test for the disorder, but testing may be done to rule out physical conditions that can cause similar symptoms. The most common time o ...

Post-traumatic Stress Disorder
Post-traumatic stress disorder (PTSD) is a mental disorder that develops from experiencing a Psychological trauma, traumatic event, such as sexual assault, domestic violence, child abuse, warfare and its associated traumas, natural disaster, traffic collision, or other threats on a person's life or well-being. Symptoms may include disturbing thoughts, feelings, or dreams related to the events, mental or physical distress (medicine), distress to Psychological trauma, trauma-related cues, attempts to avoid trauma-related cues, alterations in the way a person thinks and feels, and an increase in the fight-or-flight response. These symptoms last for more than a month after the event and can include triggers such as misophonia. Young children are less likely to show distress, but instead may express their memories through play (activity), play. Most people who experience traumatic events do not develop PTSD. People who experience interpersonal violence such as rape, other sexual ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cognitive Psychology
Cognitive psychology is the scientific study of human mental processes such as attention, language use, memory, perception, problem solving, creativity, and reasoning. Cognitive psychology originated in the 1960s in a break from behaviorism, which held from the 1920s to 1950s that unobservable mental processes were outside the realm of empirical science. This break came as researchers in linguistics and cybernetics, as well as applied psychology, used models of mental processing to explain human behavior. Work derived from cognitive psychology was integrated into other branches of psychology and various other modern disciplines like cognitive science, linguistics, and economics. History Philosophically, ruminations on the human mind and its processes have been around since the times of the Ancient Greece, ancient Greeks. In 387 BCE, Plato had suggested that the brain was the seat of the mental processes. In 1637, René Descartes posited that humans are born with innate ideas and ...

Abnormal Psychology
Abnormal psychology is the branch of psychology that studies unusual patterns of behavior, emotion, and thought, which could possibly be understood as a mental disorder. Although many behaviors could be considered as abnormal, this branch of psychology typically deals with behavior in a clinical context. There is a long history of attempts to understand and control behavior deemed to be aberrant or deviant (statistically, functionally, morally, or in some other sense), and there is often cultural variation in the approach taken. The field of abnormal psychology identifies multiple causes for different conditions, employing diverse theories from the general field of psychology and elsewhere, and much still hinges on what exactly is meant by "abnormal". There has traditionally been a divide between psychological and biological explanations, reflecting a philosophical dualism in regard to the mind–body problem. There have also been different approaches in trying to classify ment ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stria Terminalis
The stria terminalis (or terminal stria) is a structure in the brain consisting of a band of fibers running along the lateral margin of the ventricular surface of the thalamus. Serving as a major output pathway of the amygdala, the stria terminalis runs from its centromedial division to the ventromedial nucleus of the hypothalamus. Anatomy The stria terminalis covers the superior thalamostriate vein, marking a line of separation between the thalamus and the caudate nucleus as seen upon gross dissection of the ventricles of the brain, viewed from the superior aspect. The stria terminalis extends from the region of the interventricular foramina to the temporal horn of the lateral ventricle, carrying fibers from the amygdala to the septal nuclei, hypothalamic, and thalamic areas of the brain. It also carries fibers projecting from these areas back to the amygdala. Bed nucleus of the stria terminalis The bed nucleus of the stria terminalis (BNST) is a collection of nuclei ...
