Psychology is the 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.
Happiness is a positive and pleasant emotion, ranging from contentment to intense joy. Moments of happiness may be triggered by positive life experiences or thoughts, but sometimes it may arise from no obvious cause. The level of happiness for longer periods of time is more strongly correlated with levels of life satisfaction, subjective well-being, flourishing and eudaimonia. In common usage, the word happy can be an appraisal of those measures themselves or as a shorthand for a "source" of happiness. As with any emotion, the precise definition of happiness has been a perennial debate in philosophy.
Personality is any person's collection of interrelated behavioral, cognitive and emotional patterns that comprise a person’s unique adjustment to life. These interrelated patterns are relatively stable, but can change over long time periods.
Positive psychology studies the conditions that contribute to the optimal functioning of people, groups, and institutions. It studies "positive subjective experience, positive individual traits, and positive institutions... it aims to improve quality of life."
Logotherapy was developed by neurologist and psychiatrist Viktor Frankl and is based on the premise that the primary motivational force of an individual is to find a meaning in life. Frankl describes it as "the Third Viennese School of Psychotherapy" along with Freud's psychoanalysis and Adler's individual psychology.
Dispositional affect, similar to mood, is a personality trait or overall tendency to respond to situations in stable, predictable ways. This trait is expressed by the tendency to see things in a positive or negative way. People with high positive affectivity tend to perceive things through "pink lens" while people with high negative affectivity tend to perceive things through "black lens". The level of dispositional affect affects the sensations and behavior immediately and most of the time in unconscious ways, and its effect can be prolonged. Research shows that there is a correlation between dispositional affect and important aspects in psychology and social science, such as personality, culture, decision making, negotiation, psychological resilience, perception of career barriers, and coping with stressful life events. That is why this topic is important both in social psychology research and organizational psychology research.

Positive affectivity (PA) is a human characteristic that describes how much people experience positive affects ; and as a consequence how they interact with others and with their surroundings.
Edward Francis Diener was an American psychologist and author. Diener was a professor of psychology at the University of Utah and the University of Virginia, and Joseph R. Smiley Distinguished Professor Emeritus at the University of Illinois, as well as a senior scientist for the Gallup Organization. He is noted for his research over the past thirty years on happiness, including work on temperament and personality influences on well-being, theories of well-being, income and well-being, cultural influences on well-being, and the measurement of well-being. As shown on Google Scholar as of April 2021, Diener's publications have been cited over 257,000 times.
Joseph Carroll is a scholar in the field of literature and evolution. He received his PhD in Comparative Literature from the University of California, Berkeley and is now Curators’ Distinguished Professor Emeritus at the University of Missouri–St. Louis.
In positive psychology, a meaningful life is a construct having to do with the purpose, significance, fulfillment, and satisfaction of life. While specific theories vary, there are two common aspects: a global schema to understand one's life and the belief that life itself is meaningful. Meaning can be defined as the connection linking two presumably independent entities together; a meaningful life links the biological reality of life to a symbolic interpretation or meaning. Those possessing a sense of meaning are generally found to be happier, to have lower levels of negative emotions, and to have lower risk of mental illness.
The VIA Inventory of Strengths (VIA-IS), formerly known as the "Values in Action Inventory," is a proprietary psychological assessment measure designed to identify an individual's profile of "character strengths".
Experiential avoidance (EA) has been broadly defined as attempts to avoid thoughts, feelings, memories, physical sensations, and other internal experiences — even when doing so creates harm in the long run. The process of EA is thought to be maintained through negative reinforcement — that is, short-term relief of discomfort is achieved through avoidance, thereby increasing the likelihood that the avoidance behavior will persist. Importantly, the current conceptualization of EA suggests that it is not negative thoughts, emotions, and sensations that are problematic, but how one responds to them that can cause difficulties. In particular, a habitual and persistent unwillingness to experience uncomfortable thoughts and feelings is thought to be linked to a wide range of problems.
Subjective well-being (SWB) is a self-reported measure of well-being, typically obtained by questionnaire.
The six-factor model of psychological well-being is a theory developed by Carol Ryff that determines six factors that contribute to an individual's psychological well-being, contentment, and happiness. Psychological well-being consists of self-acceptance, positive relationships with others, autonomy, environmental mastery, a feeling of purpose and meaning in life, and personal growth and development. Psychological well-being is attained by achieving a state of balance affected by both challenging and rewarding life events.
Cultural differences can interact with positive psychology to create great variation, potentially impacting positive psychology interventions. Culture differences have an impact on the interventions of positive psychology. Culture influences how people seek psychological help, their definitions of social structure, and coping strategies.
Optimism is an attitude reflecting a belief or hope that the outcome of some specific endeavor, or outcomes in general, will be positive, favorable, and desirable. A common idiom used to illustrate optimism versus pessimism is a glass filled with water to the halfway point: an optimist is said to see the glass as half full, while a pessimist sees the glass as half empty.
Paul T. P. Wong is a Canadian clinical psychologist and professor. His research career has gone through four stages, with significant contributions in each stage: learning theory, social cognition, existential psychology, and positive psychology. He is most known for his integrative work on death acceptance, meaning therapy, and second wave positive psychology. He has been elected as a fellow for both the American Psychological Association and the Canadian Psychological Association.
Second wave positive psychology is a therapeutic approach in psychology that attempts to bring out the best in individuals and society by incorporating the dark side of human existence through the dialectical principles of yin and yang. This represents a distinct shift from focusing on individual happiness and success to the dual vision of individual well-being and collective humanity. PP 2.0 is more about bringing out the "better angels of our nature" than achieving optimal happiness or personal success. The approach posits that empathy, compassion, reason, justice, and self-transcendence will improve humans, both individually and collectively. PP 2.0 centers around the universal human capacity for meaning-seeking and meaning-making in achieving optimal human functioning under both desirable and undesirable conditions. This emerging movement is a response to perceived problems of what some have called "positive psychology as usual."
Well-being is a multifaceted topic studied in psychology, especially positive psychology. Biologically, well-being is highly influenced by endogenous molecules that impact happiness and euphoria in organisms, often referred to as "well-being related markers". Related concepts are eudaimonia, happiness, flourishing, quality of life, contentment, and meaningful life.
