Psychology is the scientific study of mind and behavior. Its subject matter includes the behavior of humans and nonhumans, both conscious and unconscious phenomena, and mental processes such as thoughts, feelings, and motives. Psychology is an academic discipline of immense scope, crossing the boundaries between the natural and social sciences. Biological 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.
Psychotherapy is the use of psychological methods, particularly when based on regular personal interaction, to help a person change behavior, increase happiness, and overcome problems. Psychotherapy aims to improve an individual's well-being and mental health, to resolve or mitigate troublesome behaviors, beliefs, compulsions, thoughts, or emotions, and to improve relationships and social skills. Numerous types of psychotherapy have been designed either for individual adults, families, or children and adolescents. Certain types of psychotherapy are considered evidence-based for treating some diagnosed mental disorders; other types have been criticized as pseudoscience.
Histrionic personality disorder (HPD) is defined by the American Psychiatric Association as a personality disorder characterized by a pattern of excessive attention-seeking behaviors, usually beginning in early adulthood, including inappropriate seduction and an excessive desire for approval. People diagnosed with the disorder are said to be lively, dramatic, vivacious, enthusiastic, extroverted and flirtatious.
Shyness is the feeling of apprehension, lack of comfort, or awkwardness especially when a person is around other people. This commonly occurs in new situations or with unfamiliar people; a shy person may simply opt to avoid these situations. Although shyness can be a characteristic of people who have low self-esteem, the primary defining characteristic of shyness is a fear of what other people will think of a person's behavior. This fear of negative reactions such as being mocked, humiliated or patronized, criticized or rejected can cause a shy person to retreat. Stronger forms of shyness can be referred to as social anxiety or social phobia.
Avoidant personality disorder (AvPD) or anxious personality disorder is a Cluster C personality disorder characterized by excessive social anxiety and inhibition, fear of intimacy, severe feelings of inadequacy and inferiority, and an overreliance on avoidance of feared stimuli as a maladaptive coping method. Those affected typically display a pattern of extreme sensitivity to negative evaluation and rejection, a belief that one is socially inept or personally unappealing to others, and avoidance of social interaction despite a strong desire for it. It appears to affect an approximately equal number of men and women.
In psychology, trait 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 behavior, thought, and emotion. According to this perspective, traits are aspects of personality that are relatively stable over time, differ across individuals, are relatively consistent over situations, and influence behaviour. Traits are in contrast to states, which are more transitory dispositions.
Clinical psychology is an integration of human science, behavioral science, theory, and clinical knowledge for the purpose of understanding, preventing, and relieving psychologically-based distress or dysfunction and to promote subjective well-being and personal development. Central to its practice are psychological assessment, clinical formulation, and psychotherapy, although clinical psychologists also engage in research, teaching, consultation, forensic testimony, and program development and administration. In many countries, clinical psychology is a regulated mental health profession.
Sensory processing sensitivity (SPS) is a temperamental or personality trait involving "an increased sensitivity of the central nervous system and a deeper cognitive processing of physical, social, and emotional stimuli". The trait is characterized by "a tendency to 'pause to check' in novel situations, greater sensitivity to subtle stimuli, and the engagement of deeper cognitive processing strategies for employing coping actions, all of which is driven by heightened emotional reactivity, both positive and negative".
The diathesis-stress model, also known as the vulnerability–stress model, is a psychological theory that attempts to explain a disorder, or its trajectory, as the result of an interaction between a predispositional vulnerability, the diathesis, and stress caused by life experiences. The term diathesis derives from the Greek term (διάθεσις) for a predisposition or sensibility. A diathesis can take the form of genetic, psychological, biological, or situational factors. A large range of differences exists among individuals' vulnerabilities to the development of a disorder.
Sensory overload occurs when one or more of the body's senses experiences over-stimulation from the environment.
Social rejection occurs when an individual is deliberately excluded from a social relationship or social interaction. The topic includes interpersonal rejection, romantic rejection, and familial estrangement. A person can be rejected or shunned by individuals or an entire group of people. Furthermore, rejection can be either active by bullying, teasing, or ridiculing, or passive by ignoring a person, or giving the "silent treatment". The experience of being rejected is subjective for the recipient, and it can be perceived when it is not actually present. The word "ostracism" is also commonly used to denote a process of social exclusion.
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, 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 generating positive ones.
Social anxiety is the anxiety and fear specifically linked to being in social settings. Some categories of disorders associated with social anxiety include anxiety disorders, mood disorders, autism spectrum disorders, eating disorders, and substance use disorders. Individuals with higher levels of social anxiety often avert their gazes, show fewer facial expressions, and show difficulty with initiating and maintaining a conversation. Social anxiety commonly manifests itself in the teenage years and can be persistent throughout life; however, people who experience problems in their daily functioning for an extended period of time can develop social anxiety disorder. Trait social anxiety, the stable tendency to experience this anxiety, can be distinguished from state anxiety, the momentary response to a particular social stimulus. Half of the individuals with any social fears meet the criteria for social anxiety disorder. Age, culture, and gender impact the severity of this disorder. The function of social anxiety is to increase arousal and attention to social interactions, inhibit unwanted social behavior, and motivate preparation for future social situations.
Asociality refers to the lack of motivation to engage in social interaction, or a preference for solitary activities. Asociality may be associated with avolition, but it can, moreover, be a manifestation of limited opportunities for social relationships. Developmental psychologists use the synonyms nonsocial, unsocial, and social uninterest. Asociality is distinct from, but not mutually exclusive to, anti-social behavior. A degree of asociality is routinely observed in introverts, while extreme asociality is observed in people with a variety of clinical conditions.
The self-expansion model proposes that individuals seek to expand their sense of self by acquiring resources, broadening their perspectives, and increase competency to ultimately optimize their ability to thrive in their environment. It was developed in 1986 by Arthur Aron and Elaine Aron to provide a framework for the underlying experience and behavior in close relationships. The model has two distinct but related core principles: the motivational principle and the inclusion-of-other-in-self principle. The motivational principle refers to an individual's inherent desire to improve their self-efficacy and adapt, survive, and reproduce in their environment. The inclusion-of-other-in-self principle posits that close relationships serve as the primary way to expand our sense of self as we incorporate the identities, perspectives, resources, and experiences of others as our own through these relationships.
Quiet: The Power of Introverts in a World That Can't Stop Talking is a 2012 nonfiction book written by American author and speaker Susan Cain. Cain argues that modern Western culture misunderstands and undervalues the traits and capabilities of introverted people, leading to "a colossal waste of talent, energy, and happiness."
Arthur Aron is a professor of psychology at the State University of New York at Stony Brook. He is best known for his work on intimacy in interpersonal relationships, and development of the self-expansion model of motivation in close relationships.
Environmental sensitivity describes the ability of an individual to perceive and process information about their environment. It is a basic trait found in many organisms that enables an individual to adapt to different environmental conditions. Levels of Environmental Sensitivity often vary considerably from individual to individual, with some being more and others less sensitive to the same conditions. Such differences have been observed across many species such as pumpkinseed fish, zebra finches, mice, non-human primates and humans, indicating that there is a biological basis to differences in sensitivity.
Vantage sensitivity is a psychological concept related to environmental sensitivity, initially developed by Michael Pluess and Jay Belsky. It describes individual differences in response to positive experiences and supportive environmental influences. According to vantage sensitivity, people differ considerably in their sensitivity to positive aspects of the environment, with some people benefitting particularly strongly from positive experiences such as parental care, supportive relationships, and psychological interventions, whereas others tend to respond less or not at all.
