Trait Theorist
In psychology, trait theory (also called dispositional theory) is an approach to the study of human personality. Trait theorists are primarily interested in the measurement of ''traits'', which can be defined as habitual patterns of behaviour, thought, and emotion. According to this perspective, traits are aspects of personality that are relatively stable over time, differ across individuals (e.g. some people are outgoing whereas others are not), are relatively consistent over situations, and influence behaviour. Traits are in contrast to states, which are more transitory dispositions. In some theories and systems, traits are something a person either has or does not have, but in many others traits are dimensions such as extraversion vs. introversion, with each person rating somewhere along this spectrum. There are two approaches to define traits: as internal causal properties or as purely descriptive summaries. The internal causal definition states that traits influence our behav ...

Psychology
Psychology is the scientific study of mind and behavior. Psychology includes the study of conscious and unconscious phenomena, including feelings and thoughts. It is an academic discipline of immense scope, crossing the boundaries between the natural and social sciences. Psychologists seek an understanding of the emergent properties of brains, linking the discipline to neuroscience. As social scientists, psychologists aim to understand the behavior of individuals and groups.Fernald LD (2008)''Psychology: Six perspectives'' (pp.12–15). Thousand Oaks, CA: Sage Publications.Hockenbury & Hockenbury. Psychology. Worth Publishers, 2010. Ψ (''psi''), the first letter of the Greek word ''psyche'' from which the term psychology is derived (see below), is commonly associated with the science. A professional practitioner or researcher involved in the discipline is called a psychologist. Some psychologists can also be classified as behavioral or cognitive scientists. Some psyc ...

Gray's Biopsychological Theory Of Personality
The biopsychological theory of personality is a model of the general biological processes relevant for human psychology, behavior, and personality. The model, proposed by research psychologist Jeffrey Alan Gray in 1970, is well-supported by subsequent research and has general acceptance among professionals. Gray hypothesized the existence of two brain-based systems for controlling a person's interactions with their environment: the behavioural inhibition system (BIS) and the behavioural activation system (BAS). BIS is related to sensitivity to punishment and avoidance motivation. BAS is associated with sensitivity to reward and approach motivation. 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. Those with a relatively high BAS are said to be extraverted and outgoing while those with a high BIS tend to be more reserved and introverted. Psychologi ...

Sleep
Sleep is a sedentary state of mind and body. It is characterized by altered consciousness, relatively inhibited sensory activity, reduced muscle activity and reduced interactions with surroundings. It is distinguished from wakefulness by a decreased ability to react to stimuli, but more reactive than a coma or disorders of consciousness, with sleep displaying different, active brain patterns. Sleep occurs in repeating periods, in which the body alternates between two distinct modes: REM sleep and non-REM sleep. Although REM stands for "rapid eye movement", this mode of sleep has many other aspects, including virtual paralysis of the body. Dreams are a succession of images, ideas, emotions, and sensations that usually occur involuntarily in the mind during certain stages of sleep. During sleep, most of the body's systems are in an anabolic state, helping to restore the immune, nervous, skeletal, and muscular systems; these are vital processes that maintain mood, memory, ...

Schizoid Personality Disorder
Schizoid personality disorder (, often abbreviated as SzPD or ScPD) is a personality disorder characterized by a Asociality, lack of interest in social relationships, a tendency toward a solitary or sheltered lifestyle, secretiveness, emotional coldness, detachment and apathy. Affected individuals may be unable to form intimate attachments to others and simultaneously possess a rich and elaborate but exclusively internal fantasy (psychology), fantasy world. Other associated features include stilted speech, a Anhedonia, lack of deriving enjoyment from most activities, feeling as though one is an "observer" rather than a participant in life, an inability to tolerate emotional expectations of others, apparent indifference when praised or criticized, a degree of asexuality and idiosyncratic moral or political beliefs. Symptoms typically start in late childhood or adolescence. The cause of SzPD is uncertain, but there is some evidence of links and shared genetic risk between SzPD, ...

Psychopathy
Psychopathy, sometimes considered synonymous with sociopathy, is characterized by persistent Anti-social behaviour, antisocial behavior, impaired empathy and remorse, and Boldness, bold, Disinhibition, disinhibited, and Egotism, egotistical Behavior, traits. Different conceptions of psychopathy have been used throughout History of psychopathy, history that are only partly overlapping and may sometimes be contradictory. Hervey M. Cleckley, an American psychiatrist, influenced the initial diagnostic criteria for antisocial personality reaction/disturbance in the ''Diagnostic and Statistical Manual of Mental Disorders'' (''DSM''), as did American psychologist George E. Partridge. The ''DSM'' and ''International Classification of Diseases'' (ICD) subsequently introduced the diagnoses of antisocial personality disorder (ASPD) and Antisocial personality disorder#ICD-10, dissocial personality disorder (DPD) respectively, stating that these diagnoses have been referred to (or include ...
