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.
Gerontology is the study of the social, cultural, psychological, cognitive, and biological aspects of aging. The word was coined by Ilya Ilyich Mechnikov in 1903, from the Greek γέρων (gérōn), meaning "old man", and -λογία (-logía), meaning "study of". The field is distinguished from geriatrics, which is the branch of medicine that specializes in the treatment of existing disease in older adults. Gerontologists include researchers and practitioners in the fields of biology, nursing, medicine, criminology, dentistry, social work, physical and occupational therapy, psychology, psychiatry, sociology, economics, political science, architecture, geography, pharmacy, public health, housing, and anthropology.
The Big Five personality traits, sometimes known as "the five-factor model of personality" or "OCEAN model", is a grouping of five unique characteristics used to study personality. It has been developed from the 1980s onward in psychological trait theory.
Sexuality in older age concerns the sexual drive, sexual activity, interests, orientation, intimacy, self-esteem, behaviors, and overall sexuality of people in middle age and old age, and the social perceptions concerning sexuality in older age. Older people engage in a variety of sexual acts from time to time for a variety of reasons. Desire for intimacy does not disappear with age, yet there are many restrictions placed on the elderly preventing sexual expressions and discouraging the fulfillment of sexual needs. Sexuality in older age is often considered a taboo, yet it is considered to be quite a healthy practice; however, this stigma can affect how older individuals experience their sexuality. While the human body has some limits on the maximum age for reproduction, sexual activity can be performed or experienced well into the later years of life.
In psychology, personality type refers to the psychological classification of different types of individuals. Personality types are sometimes distinguished from personality traits, with the latter embodying a smaller grouping of behavioral tendencies. Types are sometimes said to involve qualitative differences between people, whereas traits might be construed as quantitative differences. According to type theories, for example, introverts and extraverts are two fundamentally different categories of people. According to trait theories, introversion and extraversion are part of a continuous dimension, with many people in the middle. In contrast to personality traits, the existence of personality types remains extremely controversial.
In the study of psychology, neuroticism has been considered a fundamental personality trait. In the Big Five approach to personality trait theory, individuals with high scores for neuroticism are more likely than average to be moody and 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. The responses can include maladaptive behaviors, such as dissociation, procrastination, substance use, etc., which aids in relieving the negative emotions and generating positive ones.
The disengagement theory of ageing states that "aging is an inevitable, mutual withdrawal or disengagement, resulting in decreased interaction between the aging person and others in the social system he belongs to". The theory claims that it is natural and acceptable for older adults to withdraw from society. There are multiple variations on disengagement theory, such as moral disengagement.
Affective events theory (AET) is an industrial and organizational psychology model developed by organizational psychologists Howard M. Weiss and Russell Cropanzano to explain how emotions and moods influence job performance and job satisfaction. The model explains the linkages between employees' internal influences and their reactions to incidents that occur in their work environment that affect their performance, organizational commitment, and job satisfaction. The theory proposes that affective work behaviors are explained by employee mood and emotions, while cognitive-based behaviors are the best predictors of job satisfaction. The theory proposes that positive-inducing as well as negative-inducing emotional incidents at work are distinguishable and have a significant psychological impact upon workers' job satisfaction. This results in lasting internal and external affective reactions exhibited through job performance, job satisfaction, and organizational commitment.
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.
"Leisure refers to activities that a person voluntarily engages in when they are free from any work, social or familial responsibilities." Leisure satisfaction is the positive perceptions or feelings that an individual forms, elicits and gains as a result of engaging in leisure activities and choices. What can contribute to leisure satisfaction is to what degree an individual is currently satisfied with their leisure experiences and activities. An individual might attain positive feelings of contentment and happiness that result from the satisfaction of needs. Participation in leisure activities and leisure satisfaction are inextricably linked to an individual's health. Caldwell suspects that leisure activities may be associated with a number of defensive traits that enhance a person's resiliency to negative life experiences. Some aspects of leisure activities that can act as protective factors include: "[the activity] being personally meaningful, intrinsically interesting and/or challenging; offering social support and friendships; contributing to a sense of competence and/or self efficacy; offering a sense of personal control, choice and self-determination; and being relaxing and/or distracting the individual from negative life events." Leisure activities, although ranging in types, have also proven to be beneficial to health cross-culturally.
Reminiscence therapy is used to counsel and support older people, and is an intervention technique with brain-injured patients and those who appear to have "Alzheimer's and other forms of cognitive disease."
The continuity theory of normal aging states that older adults will usually maintain the same activities, behaviors, relationships as they did in their earlier years of life. According to this theory, older adults try to maintain this continuity of lifestyle by adapting strategies that are connected to their past experiences.
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.
The trait of extraversion and introversion are a central dimension in some human personality theories. The terms introversion and extraversion were introduced into psychology by Carl Jung, though both the popular understanding and current psychological usage are not the same as Jung's original concept. Extraversion tends to be manifested in outgoing, talkative, energetic behavior, whereas introversion is manifested in more reflective and reserved behavior. Jung defined introversion as an "attitude-type characterised by orientation in life through subjective psychic contents", and extraversion as "an attitude-type characterised by concentration of interest on the external object".
Subjective well-being (SWB) is a self-reported measure of well-being, typically obtained by questionnaire.
Scholarly studies have investigated the effects of religion on health. The World Health Organization (WHO) discerns four dimensions of health, namely physical, social, mental, and spiritual health. Having a religious belief may have both positive and negative impacts on health and morbidity.
Most scientists agree that religiosity is not an independent personality trait, despite there being some commonality between their characteristics. Religiosity and personality traits both relate to one's feelings, thoughts, and behaviors. However, unlike for personality, one's level of religiosity is often measured by the presence or lack of belief in and relationship with a higher power, certain lifestyles or behaviors adopted for a higher power, and a sense of belonging with other followers of one's religion. Additionally, personality traits tend to follow a normal distribution, such that the majority of individuals' scores for a personality trait will be concentrated towards the middle, rather than being extremely high or low. Distributions for religiosity, however, follow a non-normal distribution, such that there are more individuals who score particularly high or low on religiosity scales.
Aging has a significant impact on society. People of different ages and gender tend to differ in many aspects, such as legal and social responsibilities, outlooks on life, and self-perceptions. Young people tend to have fewer legal privileges, they are more likely to push for political and social change, to develop and adopt new technologies, and to need education. Older people have different requirements from society and government, and frequently have differing values as well, such as for property and pension rights. Older people are also more likely to vote, and in many countries the young are forbidden from voting. Thus, the aged have comparatively more, or at least different, political influence.
Intelligence and personality have traditionally been studied as separate entities in psychology, but more recent work has increasingly challenged this view. An increasing number of studies have recently explored the relationship between intelligence and personality, in particular the Big Five personality traits.
