Interpersonal relationships
Interpersonal relationships can be evaluated by the specific choices and emotions between two individuals, or they can be evaluated by the broader societal context of how such a relationship is expected to function. Relationships are developed through communication, which creates intimacy, expresses emotions, and develops identity. An individual's interpersonal relationships form a

Politics and conflict

When humans make decisions as a group, they engage in politics. Humans have evolved to engage in behaviors of
self-interest, but this also includes behaviors that facilitate cooperation rather than conflict in collective settings. Individuals will often form
in-group and out-group perceptions, through which individuals cooperate with the in-group and compete with the out-group. This causes behaviors such as unconsciously conforming, passively obeying authority, taking pleasure in the misfortune of opponents, initiating hostility toward out-group members, artificially creating out-groups when none exist, and punishing those that do not comply with the standards of the in-group. These behaviors lead to the creation of
political systems that enforce in-group standards and norms.
When humans oppose one another, it creates conflict. It may occur when the involved parties have a
disagreement of opinion, when one party obstructs the goals of another, or when parties experience negative emotions such as
anger
Anger, also known as wrath or rage, is an intense emotional state involving a strong uncomfortable and non-cooperative response to a perceived provocation, hurt or threat.

toward one another. Conflicts purely of disagreement are often resolved through communication or
negotiation, but incorporation of emotional or obstructive aspects can escalate conflict.
Interpersonal conflict is that between specific individuals or groups of individuals.
Social conflict is that between different social groups or demographics. This form of conflict often takes place when groups in society are marginalized, do not have the resources they desire, wish to instigate social change, or wish to resist social change. Significant social conflict can cause
civil disorder.
International conflict is that between nations or governments. It may be solved through

, fear, Surprise (emotion), surprise, and disgust are common to all cultures, though social norms regarding the expression of emotion may vary. Other emotions come from higher cognition, such as love, Guilt (emotion), guilt, shame, embarrassment, pride, envy, and jealousy. These emotions develop over time rather than instantly and are more strongly influenced by cultural factors. Emotions are influenced by sensory information, such as color and music, and Mood (psychology), moods of happiness and sadness. Humans typically maintain a standard level of happiness or sadness determined by health and social relationships, though positive and negative events have short-term influences on mood. Humans often seek to improve the moods of one another through consolation, entertainment, and complaining, venting. Humans can also self-regulate mood through exercise and meditation.
Creativity is the use of previous ideas or resources to produce something original. It allows for innovation, adaptation to change, learning new information, and novel problem solving. Expression of creativity also supports quality of life. Creativity includes personal creativity, in which a person presents new ideas Authenticity (philosophy), authentically, but it can also be expanded to social creativity, in which a community or society produces and recognizes ideas collectively. Creativity is applied in typical human life to solve problems as they occur. It also leads humans to carry out art and science. Individuals engaging in advanced creative work typically have specialized knowledge in that field, and humans draw on this knowledge to develop novel ideas. In art, creativity is used to develop new artistic works, such as Visual arts, visual art or music. In science, those with knowledge in a particular scientific field can use trial and error to develop theories that more accurately explain phenomena.
Religious behavior is a set of traditions that are followed based on the teachings of a religious belief system. The nature of religious behavior varies depending on the specific religious traditions. Most religious traditions involve variations of telling myths, practicing rituals, making certain things taboo, adopting Religious symbol, symbolism, determining morality, experiencing Altered state of consciousness, altered states of consciousness, and believing in supernatural beings. Religious behavior is often demanding and has high time, energy, and material costs, and it conflicts with Rational choice theory, rational choice models of human behavior, though it does provide community-related benefits. Anthropologists offer competing theories as to why humans adopted religious behavior. Religious behavior is heavily influenced by social factors, and group involvement is significant in the development of an individual's religious behavior. Social structures such as religious organizations or family units allow the sharing and coordination of religious behavior. These social connections reinforce the cognitive behaviors associated with religion, encouraging orthodoxy and commitment. According to a Pew Research Center report, 54% of adults around the world state that religion is very important in their lives as of 2018.
Physiological behavior

Humans undergo many behaviors common to animals to support the processes of the human body. Humans eat food to obtain nutrition. These foods may be chosen for their nutritional value, but they may also be Hedonic hunger, eaten for pleasure. Eating often follows a food preparation process to make it more enjoyable. Humans dispose of excess food through Human waste, waste. Excrement is often treated as taboo, particularly in developed and urban communities where sanitation is more widely available and excrement has no value as fertilizer. Humans also regularly engage in sleep, based on homeostatic and circadian factors. The circadian rhythm causes humans to require sleep at a regular pattern and is typically calibrated to the day-night cycle and sleep-wake habits. Homeostasis is also be maintained, causing longer sleep longer after periods of sleep deprivation. The human sleep cycle takes place over 90 minutes, and it repeats 3-5 times during normal sleep.
There are also unique behaviors that humans undergo to maintain physical health. Humans have developed medicine to prevent and treat illnesses. In industrialized nations, eating habits that favor better nutrition, hygienic behaviors that promote sanitation, medical treatment to eradicate diseases, and the use of birth control significantly improve human health. Humans can also engage in exercise beyond that required for survival to maintain health. Humans engage in hygiene to limit exposure to dirt and Pathogen, pathogens. Some of these behaviors are adaptive while others are learned. Basic behaviors of disgust evolved as an adaptation to prevent contact with sources of pathogens, resulting in a biological aversion to feces, body fluids, rotten food, and animals that are commonly disease vectors. Personal grooming, disposal of human corpses, use of sewerage, and use of cleaning agents are hygienic behaviors common to most human societies.
Humans are Bipedalism, bipedal and move by walking. Human walking corresponds to the bipedal gait cycle, which involves alternating heel contact and toe off with the ground and slight elevation and rotation of the pelvis. Balance while walking learned during the first 7–9 years of life, and individual humans develop unique gaits while learning to displace weight, adjust center of mass, and correspond neural control with movement. Humans can achieve higher speed by running. The Endurance_running_hypothesis#"No_horse_or_dog_could_possibly…" , endurance running hypothesis proposes that humans can outpace most other animals over long distances through running, though human running causes a higher rate of energy exertion. The human body self-regulates through perspiration during periods of exertion, allowing humans more endurance than other animals. The human hand is Prehensility, prehensile and capable of grasping objects and applying force with control over the hand's dexterity and grip strength. This allows the use of complex tools by humans.
Economic behavior
Humans engage in predictable behaviors when considering economic decisions, and these behaviors may or may not be Rationality, rational. Like all animals, humans make basic decisions through cost–benefit analysis and the risk–return spectrum, though humans are able to contemplate these decisions more thoroughly. Human economic decision making is often Reference dependence, reference dependent, in which options are weighed in reference to the status quo rather than absolute gains and losses. Humans are also Loss aversion, loss averse, fearing loss rather than seeking gain. Advanced economic behavior developed in humans after the Neolithic Revolution and the development of agriculture. These developments led to a sustainable supply of resources that allowed Specialization of labor, specialization in more complex societies.
Work
The nature of human work is defined by the complexity of society. The simplest societies are Tribe, tribes that work primarily for sustenance as hunter-gatherers. In this sense, work is not a distinct activity but a constant that makes up all parts of life, as all members of the society must work consistently to stay alive. More advanced societies developed after the Neolithic Revolution, emphasizing work in agricultural and Pastoralism, pastoral settings. In these societies, production is increased, ending the need for constant work and allowing some individuals to specialize and work in areas outside of food-production. This also created non-laborious work, as increasing occupational complexity required some individuals to specialize in technical knowledge and administration. Laborious work in these societies has variously been carried out by slaves, serfs, peasants, and guild craftsmen. The nature of work changed significantly during the Industrial Revolution in which the factory system was developed for use by industrializing nations. In addition to further increasing general quality of life, this development changed the dynamic of work. Under the factory system, workers increasingly collaborate with others, employers serve as authority figures during work hours, and forced labor is largely eradicated. Further changes occur in Post-industrial society, post-industrial societies where technological advance makes industries obsolete, replacing them with mass production and service industries.
Humans approach work differently based on both physical and personal attributes, and some work with more effectiveness and commitment than others. Some find work to contribute to personal fulfillment, while others work only out of necessity. Work can also serve as an identity, with individuals identifying themselves based on their occupation. Work motivation is complex, both contributing to and subtracting from various human needs. The primary motivation for work is for material gain, which takes the form of money in modern societies. It may also serve to create self-esteem and personal worth, provide activity, gain respect, and express creativity. Modern work is typically categorized as laborious or Blue-collar worker, blue-collar work and non-laborious or White-collar worker, white-collar work.
Leisure

Leisure is activity or lack of activity that takes place outside of work. It provides relaxation, entertainment, and improved quality of life for individuals. Casual leisure behaviors provide short-term gratification, but they do not provide long-term gratification or personal identity. These include Play (activity), play, relaxation, casual social interaction, volunteering, passive entertainment, active entertainment, and sensory stimulation. Passive entertainment is typically derived from mass media, which may include written works or digital media. Active entertainment involves games in which individuals participate. Sensory stimulation is immediate gratification from behaviors such as eating or sex. Serious leisure behaviors involve non-professional pursuit of arts and sciences, the development of Hobby, hobbies, or career volunteering in an area of expertise. Leisure can be beneficial for physical and mental health. It may be used to seek temporary relief from psychological stress, to produce positive emotions, or to facilitate social interaction. Leisure can also facilitate health risks and negative emotions caused by boredom, substance abuse, or Risk, high-risk behavior.
Consumption
Humans operate as consumers that obtain and use goods. All production is ultimately designed for Consumption (economics), consumption, and consumers adapt their behavior based on the availability of production. Mass consumption began during the Industrial Revolution, caused by the development of new technologies that allowed for increased production.
Many factors affect a consumer's decision to purchase goods through trade. They may consider the nature of the product, its associated cost, the convenience of purchase, and the nature of advertising around the product. Cultural factors may influence this decision, as different cultures value different things, and subcultures within these cultures may have distinct priorities as buyers. Social class, including wealth, education, and occupation may affect one's purchasing behavior. A consumer's interpersonal relationships and reference groups may also influence purchasing behavior.
Ecological behavior

Like all living things, humans live in ecosystems and interact with other organisms. Human behavior is affected by the environment in which a human lives, and environments are affected by human habitation. Humans have also developed man-made ecosystems such as urban areas and agricultural land. Geography and landscape ecology determine how humans are distributed within an ecosystem, both naturally and through planned urban morphology.
Humans exercise control over the animals that live within their environment. Domesticated animals are trained and cared for by humans. Humans can develop social and emotional bonds with animals in their care. Pet, Pets are kept for companionship within human homes, including dogs and cats that have been bred for domestication over many centuries. Livestock animals, such as cattle, sheep, goats, and poultry, are kept on agricultural land to produce animal products. Domesticated animals are also kept in laboratories for animal testing. Non-domesticated animals are sometimes kept in nature reserves and zoos for tourism and Conservation biology, conservation.
Factors
Human behavior is influenced by biological and cultural elements. The structure and agency debate considers whether human behavior is predominantly led by individual human impulses or by external structural forces.
Behavioral genetics considers how human behavior is affected by inherited traits. Though genes do not guarantee certain behaviors, certain traits can be inherited that make individuals more likely to engage in certain behaviors or express certain personalities. An individual's environment can also affect behavior, often in conjunction with genetic factors. An individual's personality and Attitude (psychology), attitudes affect how behaviors are expressed, formed in conjunction by genetic and environmental factors.
Age
While specific traits of one's personality, temperament, and genetics may be more consistent, other behaviors change as one moves between life stages—i.e., from birth through adolescence, adulthood, and, for example, parenthood and retirement.
Infant, Infants are limited in their ability to interpret their surroundings shortly after birth. Object permanence and understanding of motion typically develop within the first six months of an infant's life, though the specific cognitive processes are not understood. The ability to mentally categorize different concepts and objects that they perceive also develops within the first year. Infants are quickly able to discern their body from their surroundings and often take interest in their own limbs or actions they cause by two months of age. Infants practice imitation of other individuals to engage socially and learn new behaviors. In young infants, this involves imitating Facial expression, facial expressions, and imitation of tool use takes place within the first year. Communication develops over the first year, and infants begin using Gesture, gestures to communicate intention around nine to ten months of age. Verbal communication develops more gradually, taking form during the second year of age.
Adolescents undergo changes in behavior caused by puberty and the associated changes in hormone production. Production of testosterone increases sensation seeking and Reward system, sensitivity to rewards in adolescents as well as aggression and risk-taking in adolescent boys. Production of estradiol causes similar risk-taking behavior among adolescent girls. The new hormones cause changes in emotional processing that allow for close friendships, stronger motivations and intentions, and adolescent sexuality. Adolescents undergo social changes on a large scale, developing a self-concept and making autonomous decisions independently of adults. They typically become more aware of social norms and social cues than children, causing an increase in self-consciousness and adolescent egocentrism that guides behavior in social settings throughout adolescence.
Disability
Physical disability, Physical disabilities can prevent individuals from engaging in typical human behavior or necessitate alternative behaviors. Accommodations and accessibility are often made available for individuals with physical disabilities in developed nations, including health care, assistive technology, and Vocational rehabilitation, vocational services. Severe disabilities are associated with increased leisure time but also with a lower satisfaction in the quality of leisure time. Productivity and health both commonly undergo long term decline following the onset of a severe disability. Disabilities affecting intellectual abilities, Mental disabilities are those that directly affect cognitive and social behavior. Common Mental disorder, mental disorders include Mood disorder, mood disorders, Anxiety disorder, anxiety disorders, Personality disorder, personality disorders, and substance dependence.
