Gray's Biopsychological Theory Of Personality
Gray's biopsychological theory of personality is a model of the general biological processes relevant for human psychology, behavior, and personality, proposed by research psychologist Jeffrey Alan Gray in 1970. The theory is well-supported by subsequent research and has general acceptance among professionals. Gray hypothesized the existence of three brain-based systems for controlling a person's interactions with their environment: the behavioural inhibition system (BIS) and the behavioural activation system (BAS), and the fight, flight, or freezing system (FFFS). BIS is related to sensitivity to punishment and avoidance motivation. BAS is associated with sensitivity to reward and approach motivation. FFFS is associated with sensitivity to fear and how an individual responds to it. There is evidence that the Behavioral Inhibition and Behavioral Activations system are connected to mood control, with positive or negative emotions occurring when rewarded or punished.

Jeffrey Alan Gray
Jeffrey Alan Gray (26 May 1934 – 30 April 2004) was a British research psychologist. He is known for his Gray's biopsychological theory of personality, biopsychological theory of personality. He is also notable for his contributions to the theory of consciousness. Life and work He was born in the East End of London. His father was a tailor, but died when Jeffrey was only seven. His mother, who ran a haberdashery, brought him up alone. Following military service (1952–54), he took up a MacKinnon scholarship at Magdalen College, Oxford, with a place to study Law. In the event he negotiated a switch to Modern Languages, obtaining a first in French and Spanish. He stayed on to take a second BA, this time in Psychology and Philosophy, which he completed in 1959. In 1959–60 he trained as a clinical psychologist at the Institute of Psychiatry in London (now part of King's College London), after which he stayed on to study for a PhD in the department of psychology, headed by Ha ...

ADHD
Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterised by symptoms of inattention, hyperactivity, impulsivity, and emotional dysregulation that are excessive and pervasive, impairing in multiple contexts, and developmentally inappropriate. ADHD symptoms arise from executive dysfunction. Impairments resulting from deficits in self-regulation such as time management, inhibition, task initiation, and sustained attention can include poor professional performance, relationship difficulties, and numerous health risks, collectively predisposing to a diminished quality of life and a reduction in life expectancy. As a consequence, the disorder costs society hundreds of billions of US dollars each year, worldwide. It is associated with other mental disorders as well as non-psychiatric disorders, which can cause additional impairment. While ADHD involves a lack of sustained attention to tasks, inhibitory deficits also can lead to diffic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Criminal Profiling
Offender profiling, also known as criminal profiling, is an investigative strategy used by law enforcement agencies to identify likely suspects and has been used by investigators to link cases that may have been committed by the same perpetrator. There are multiple approaches to offender profiling, including the FBI’s typological method, geographic profiling, and investigative psychology, each utilizing different techniques to analyze offender behavior. Profiling is primarily applied in cases involving violent crimes such as serial murder, sexual offenses, and arson, where behavioral patterns may provide investigative leads. Despite its use in law enforcement, offender profiling remains controversial, with critics arguing that it often lacks empirical validation, relies heavily on subjective interpretation, and may contribute to cognitive biases in criminal investigations. Advances in forensic psychology and data-driven methodologies continue to shape the field, integrating psy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Interpersonal And Social Rhythm Therapy
Interpersonal and social rhythm therapy (IPSRT) is an intervention for people with bipolar disorder (BD). Its primary focus is stabilizing the circadian rhythm disruptions that are common among people with bipolar disorder (BD). IPSRT draws upon principles from interpersonal psychotherapy, an evidence-based treatment for depression and emphasizes the importance of daily routine (rhythm). IPSRT was developed by Ellen Frank, PhD at the University of Pittsburgh who published a book on her theories: ''Treating Bipolar Disorder, a Clinician's Guide to Interpersonal and Social Rhythm Therapy''. Her research on IPSRT has shown that, in combination with medication, solving interpersonal problems and maintaining regular daily rhythms of sleeping, waking, eating, and exercise can increase quality of life, reduce mood symptoms, and help prevent relapse in people with BD. __TOC__ Social Zeitgeber Hypothesis ''Zeitgebers'' (“time givers”) are environmental cues that synchronize biologic ...

Psychoeducation
Psychoeducation (a portmanteau of psychological education) is an evidence-based therapeutic intervention for patients and their loved ones that provides information and support to better understand and cope with illness. Psychoeducation is most often associated with serious mental illness, including dementia, schizophrenia, clinical depression, anxiety disorders, eating disorders, bipolar disorder and personality disorders. The term has also been used for programs that address physical illnesses, such as cancer. Psychoeducation offered to patients and family members teaches problem-solving and communication skills and provides education and resources in an empathetic and supportive environment. Results from more than 30 studies indicate psychoeducation improves family well-being, lowers rates of relapse and improves recovery. Overview Professionally-delivered psychoeducation is a potential resource for both individuals with serious mental illness (SMI) and their family members. Th ...

Cognitive Behavioral Therapy
Cognitive behavioral therapy (CBT) is a form of psychotherapy that aims to reduce symptoms of various mental health conditions, primarily depression, PTSD, and anxiety disorders. Cognitive behavioral therapy focuses on challenging and changing cognitive distortions (thoughts, beliefs, and attitudes) and their associated behaviors in order to improve emotional regulation and help the individual develop coping strategies to address problems. Though originally designed as an approach to treat depression, CBT is often prescribed for the evidence-informed treatment of many mental health and other conditions, including anxiety, substance use disorders, marital problems, ADHD, and eating disorders. CBT includes a number of cognitive or behavioral psychotherapies that treat defined psychopathologies using evidence-based techniques and strategies. CBT is a common form of talk therapy based on the combination of the basic principles from behavioral and cognitive psychology. I ...

Depressive Episode
A major depressive episode (MDE) is a period characterized by symptoms of major depressive disorder. Those affected primarily exhibit a depressive mood for at least two weeks or more, and a loss of interest or pleasure in everyday activities. Other symptoms can include feelings of emptiness, hopelessness, anxiety, worthlessness, guilt, irritability, changes in appetite, difficulties in concentration, difficulties remembering details, making decisions, and thoughts of suicide. Insomnia or hypersomnia and aches, pains, or digestive problems that are resistant to treatment may also be present. Although the exact origin of depression is unclear, it is believed to involve biological, psychological, and social aspects. Socioeconomic status, life experience, genetics, and personality traits are believed to be factors in the development of depression and may represent an increased risk of developing a major depressive episode. In the 19th century, the term "depression" was first used a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Bipolar Disorders
Bipolar disorder (BD), previously known as manic depression, is a mental disorder characterized by periods of depression and periods of abnormally elevated mood that each last from days to weeks, and in some cases months. If the elevated mood is severe or associated with psychosis, it is called ''mania''; if it is less severe and does not significantly affect functioning, it is called ''hypomania''. During mania, an individual behaves or feels abnormally energetic, happy, or irritable, and they often make impulsive decisions with little regard for the consequences. There is usually, but not always, a reduced need for sleep during manic phases. During periods of depression, the individual may experience crying, have a negative outlook on life, and demonstrate poor eye contact with others. The risk of suicide is high. Over a period of 20 years, 6% of those with bipolar disorder died by suicide, with about one-third attempting suicide in their lifetime. Among those with the d ...

Neuroticism
Neuroticism is a personality trait associated with negative emotions. It is one of the Big Five traits. Individuals with high scores on neuroticism are more likely than average to experience such feelings as anxiety, worry, fear, anger, shame, frustration, envy, jealousy, pessimism, guilt, depressed mood, and loneliness. Such people are thought to respond worse to stressors and are more likely to interpret ordinary situations, such as minor frustrations, as appearing hopelessly difficult. Their behavioral responses may include procrastination, substance use, and other maladaptive behaviors, which may temporarily aid in relieving negative emotions and in generating positive ones. People with high scores on the neuroticism index are thought to be at risk of developing common mental disorders ( mood disorders, anxiety disorders, and substance use disorders have been studied), and the sorts of symptoms once referred to as " neuroses". Individuals who score low in neu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Alcohol Use Disorder
Alcoholism is the continued drinking of alcohol despite it causing problems. Some definitions require evidence of dependence and withdrawal. Problematic use of alcohol has been mentioned in the earliest historical records. The World Health Organization (WHO) estimated there were 283 million people with alcohol use disorders worldwide . The term ''alcoholism'' was first coined in 1852, but ''alcoholism'' and ''alcoholic'' are considered stigmatizing and likely to discourage seeking treatment, so diagnostic terms such as ''alcohol use disorder'' and ''alcohol dependence'' are often used instead in a clinical context. Alcohol is addictive, and heavy long-term alcohol use results in many negative health and social consequences. It can damage all the organ systems, but especially affects the brain, heart, liver, pancreas, and immune system. Heavy alcohol usage can result in trouble sleeping, and severe cognitive issues like dementia, brain damage, or Wernicke–Korsakoff ...

Substance Use Disorder
Substance use disorder (SUD) is the persistent use of drugs despite substantial harm and adverse consequences to self and others. Related terms include ''substance use problems'' and ''problematic drug or alcohol use''. Along with substance-induced disorders (SID) they are encompassed in the category substance-related disorders. Substance use disorders vary with regard to the average age of onset. It is not uncommon for those who have SUD to also have other mental health disorders. Substance use disorders are characterized by an array of mental, emotional, physical, and behavioral problems such as chronic guilt; an inability to reduce or stop consuming the substance(s) despite repeated attempts; operating vehicles while intoxicated; and physiological withdrawal symptoms. Drug classes that are commonly involved in SUD include: alcohol (alcoholism); cannabis; opioids; stimulants such as nicotine (including tobacco), cocaine and amphetamines; benzodiazepines; barbiturates; a ...

Brainstem
The brainstem (or brain stem) is the posterior stalk-like part of the brain that connects the cerebrum with the spinal cord. In the human brain the brainstem is composed of the midbrain, the pons, and the medulla oblongata. The midbrain is continuous with the thalamus of the diencephalon through the tentorial notch, and sometimes the diencephalon is included in the brainstem. The brainstem is very small, making up around only 2.6 percent of the brain's total weight. It has the critical roles of regulating heart and respiratory system, respiratory function, helping to control heart rate and breathing rate. It also provides the main motor and sensory nerve supply to the face and neck via the cranial nerves. Ten pairs of cranial nerves come from the brainstem. Other roles include the regulation of the central nervous system and the body's sleep cycle. It is also of prime importance in the conveyance of motor and sensory pathways from the rest of the brain to the body, and from the b ...
