Symbiosis is any type of a close and long-term biological interaction, between two organisms of different species. The two organisms, termed symbionts, can be either in a mutualistic, a commensalistic, or a parasitic relationship. In 1879, Heinrich Anton de Bary defined symbiosis as "the living together of unlike organisms".
Emotional intelligence (EI), also known as Emotional Quotient (EQ), is the ability to perceive, use, understand, manage, and handle emotions. High emotional intelligence includes emotional recognition of emotions of the self and others, using emotional information to guide thinking and behavior, discerning between and labeling of different feelings, and adjusting emotions to adapt to environments.
A child (pl. children) is a human being between the stages of birth and puberty, or between the developmental period of infancy and puberty. The term may also refer to an unborn human being. In English-speaking countries, the legal definition of child generally refers to a minor, in this case as a person younger than the local age of majority, regardless of their physical, mental and sexual development as biological adults. Children generally have fewer rights and responsibilities than adults. They are generally classed as unable to make serious decisions.
Borderline personality disorder (BPD), also known as emotionally unstable personality disorder (EUPD), is a personality disorder characterized by a pervasive, long-term pattern of significant interpersonal relationship instability, a distorted sense of self, and intense emotional responses. People diagnosed with BPD frequently exhibit self-harming behaviours and engage in risky activities, primarily due to challenges regulating emotional states to a healthy, stable baseline. Symptoms such as dissociation, a pervasive sense of emptiness, and an acute fear of abandonment are prevalent among those affected.
Conduct disorder (CD) is a mental disorder diagnosed in childhood or adolescence that presents itself through a repetitive and persistent pattern of behavior that includes theft, lies, physical violence that may lead to destruction, and reckless breaking of rules, in which the basic rights of others or major age-appropriate norms are violated. These behaviors are often referred to as "antisocial behaviors", and is often seen as the precursor to antisocial personality disorder; however, the latter, by definition, cannot be diagnosed until the individual is 18 years old. Conduct disorder may result from parental rejection and neglect and can be treated with family therapy, as well as behavioral modifications and pharmacotherapy. Conduct disorder is estimated to affect 51.1 million people globally as of 2013.
Sadness is an emotional pain associated with, or characterized by, feelings of disadvantage, loss, despair, grief, helplessness, disappointment and sorrow. An individual experiencing sadness may become quiet or lethargic, and withdraw themselves from others. An example of severe sadness is depression, a mood which can be brought on by major depressive disorder or persistent depressive disorder. Crying can be an indication of sadness.
Repressed memory is a controversial, and largely scientifically discredited, psychiatric phenomenon which involves an inability to recall autobiographical information, usually of a traumatic or stressful nature. The concept originated in psychoanalytic theory where repression is understood as a defense mechanism that excludes painful experiences and unacceptable impulses from consciousness. Repressed memory is presently considered largely unsupported by research. Sigmund Freud initially claimed the memories of historical childhood trauma could be repressed, while unconsciously influencing present behavior and emotional responding; he later revised this belief.
Psychological abuse, often known as emotional abuse or psychological violence, is a form of abuse characterized by a person subjecting or exposing another person to a behavior that may result in psychological trauma, including anxiety, chronic depression, clinical depression or post-traumatic stress disorder amongst other psychological problems.
Emotional labor is the process of managing feelings and expressions to fulfill the emotional requirements of a job. More specifically, workers are expected to regulate their personas during interactions with customers, co-workers, clients, and managers. This includes analysis and decision-making in terms of the expression of emotion, whether actually felt or not, as well as its opposite: the suppression of emotions that are felt but not expressed. This is done so as to produce a certain feeling in the customer or client that will allow the company or organization to succeed.
Attachment theory is a psychological and evolutionary framework concerning the relationships between humans, particularly the importance of early bonds between infants and their primary caregivers. Developed by psychiatrist and psychoanalyst John Bowlby (1907–90), the theory posits that infants need to form a close relationship with at least one primary caregiver to ensure their survival, and to develop healthy social and emotional functioning.
An intimate relationship is an interpersonal relationship that involves emotional or physical closeness between people and may include sexual intimacy and feelings of romance or love. Intimate relationships are interdependent, and the members of the relationship mutually influence each other. The quality and nature of the relationship depends on the interactions between individuals, and is derived from the unique context and history that builds between people over time. Social and legal institutions such as marriage acknowledge and uphold intimate relationships between people. However, intimate relationships are not necessarily monogamous or sexual, and there is wide social and cultural variability in the norms and practices of intimacy between people.
In trait theory, the Big Five personality traits are a group of five characteristics used to study personality:
Peter Pan Syndrome is a pop psychology term used to describe an adult who is socially immature. It refers to “never-growing” adults who have reached an adult age, but cannot face their adult sensations and responsibilities. The term is a metaphor based on the concept of not growing up and being trapped in childhood. Individuals with Peter Pan Syndrome display behaviours associated with immaturity and a reluctance to grow up. They have difficulties in social and professional relationships because of their irresponsible behaviours and narcissistic properties. While it has often only been associated with males in the past, it can affect anyone, regardless of sex or gender.
Neurodevelopmental disorders are a group of mental conditions affecting the development of the nervous system, which includes the brain and spinal cord. According to the American Psychiatric Association Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, (DSM-5) published in 2013, these conditions generally appear in early childhood, usually before children start school, and can persist into adulthood. The key characteristic of all these disorders is that they negatively impact a person's functioning in one or more domains of life depending on the disorder and deficits it has caused. All of these disorders and their levels of impairment exist on a spectrum, and affected individuals can experience varying degrees of symptoms and deficits, despite having the same diagnosis.
Emotional dysregulation is characterized by an inability to flexibly respond to and manage emotional states, resulting in intense and prolonged emotional reactions that deviate from social norms, given the nature of the environmental stimuli encountered. Such reactions not only deviate from accepted social norms but also surpass what is informally deemed appropriate or proportional to the encountered stimuli.
The self-regulation of emotion or emotion regulation is the ability to respond to the ongoing demands of experience with the range of emotions in a manner that is socially tolerable and sufficiently flexible to permit spontaneous reactions as well as the ability to delay spontaneous reactions as needed. It can also be defined as extrinsic and intrinsic processes responsible for monitoring, evaluating, and modifying emotional reactions. The self-regulation of emotion belongs to the broader set of emotion regulation processes, which includes both the regulation of one's own feelings and the regulation of other people's feelings.
Childhood amnesia, also called infantile amnesia, is the inability of adults to retrieve episodic memories before the age of three to four years. It may also refer to the scarcity or fragmentation of memories recollected from early childhood, particularly occurring between the ages of 3 and 6. On average, this fragmented period wanes off at around 4.7 years. Around 5–6 years of age in particular is thought to be when autobiographical memory seems to stabilize and be on par with adults. The development of a cognitive self is also thought by some to have an effect on encoding and storing early memories.
The study of the relationship between gender and emotional expression is the study of the differences between men and women in behavior that expresses emotions. These differences in emotional expression may be primarily due to cultural expectations of femininity and masculinity.
Social emotional development represents a specific domain of child development. It is a gradual, integrative process through which children acquire the capacity to understand, experience, express, and manage emotions and to develop meaningful relationships with others. As such, social emotional development encompasses a large range of skills and constructs, including, but not limited to: self-awareness, joint attention, play, theory of mind, self-esteem, emotion regulation, friendships, and identity development.
In the field of personality psychology, Machiavellianism is the name of a personality trait construct characterized by interpersonal manipulation, indifference to morality, lack of empathy, and a calculated focus on self-interest. Psychologists Richard Christie and Florence L. Geis named the construct after Niccolò Machiavelli, as they used truncated and edited statements similar to his writing style to study variations in human behaviors. Their Mach IV test, a 20-question, Likert-scale personality survey, became the standard self-assessment tool and scale of the Machiavellianism construct. Those who score high on the scale are more likely to have a high level of manipulativeness, deceitfulness and a cynical, unemotional temperament.
