Attachment & Interpersonal Theory

Theory Overview

Bowlby argued that the emotional bond (attachment) with a caregiver in infancy forms the lifelong foundation for interpersonal relations, emotion regulation, and self-concept. The concept of a safe base explains the principle that the presence of a trusted other enables exploration, growth, and autonomy.

Safe Base

A psychological zone of safety provided by a trusted attachment figure. Their mere presence enables exploration, growth, and autonomous behavior.

Separation Anxiety

Anxiety triggered by separation from the attachment figure. The mechanism behind the "fundamental sense of emptiness" when fulfillment is interrupted.

Internal Working Model

A cognitive schema of interpersonal relations formed from early attachment experiences. It influences the capacity to receive benefit and the level of distrust.

Referenced Relations

Duality (secure attachment and fulfillment) Distrust (sealing off the capacity to receive benefit) Apprentice (growth while receiving support) Beneficiary (fulfillment and trust)

Bowlby, J. (1969). Attachment and Loss, Vol.1. Hogarth Press. / (1973). Separation. / (1980). Loss.

Theory Overview

Bartholomew & Horowitz classified adult attachment styles along two axes — "model of self (positive/negative)" and "model of other (positive/negative)" — into four categories. In particular, fearful-avoidant — a style holding the conflict of "wanting to approach but unable to trust" — is centrally used to explain the psychological mechanism of the Distrust relation.

secure

Both self and other are positive. Stable relationship-building is possible. The psychological state closest to the Duality relation.

fearful-avoidant

Both self and other are negative. The conflict of "wanting to approach but afraid of being hurt." The core of the Distrust relation's simultaneous attraction and avoidance.

dismissing

Self positive, other negative. Connects to the "no need for others" sense of the Distance relation.

Referenced Relations

Distrust (fearful-avoidant conflict structure)

Bartholomew, K., & Horowitz, L. M. (1991). Attachment styles among young adults. Journal of Personality and Social Psychology, 61(2), 226–244.

Theory Overview

Baumeister & Leary argued that the desire for stable, positive relationships with others is one of the most fundamental human motivations. When the need to belong is fulfilled, defensive and compulsive behavior patterns (Doing mode) recede. This principle is referenced as the psychological foundation for the linked mechanism in the Duality relation: "fulfillment of craving → suppression of the background block."

Referenced Relations

Duality (belongingness and attachment fulfillment suppress the background core) Belonging (sense of belongingness and interdependence)

Baumeister, R. F., & Leary, M. R. (1995). The need to belong. Psychological Bulletin, 117(3), 497–529.

Theory Overview

Winnicott argued that when the responsiveness of the caregiving environment is low, the child hides the "originally spontaneous self (true self)" and develops a "false self" to adapt to the environment. The false self maintains social functioning but inhibits deep fulfillment and creative spontaneity. Over-adaptation to obligation, role demands, and social expectations activates the false self and suppresses spontaneity and creativity. In the Mirror relation, when the sense of obligation recedes the true self tends to emerge; in the Role and Formal relations, the false self is structurally induced.

Referenced Relations

Mirror (true self emerges as obligation recedes) Role (structural induction of false self and social compliance) Formal (reaction formation and rationalization = activation of the false self)

Motivation & Flow Theory

Theory Overview

Deci & Ryan's Self-Determination Theory (SDT) proposes "autonomy, competence, and relatedness" as the three basic psychological needs that support human intrinsic motivation. External coercion, evaluation, and obligation (extrinsic motivation) reduce intrinsic motivation (the undermining effect). The principle that intrinsic motivation drops directly when the relatedness need is blocked (sense of "no need for others," defensive closure) is used to explain the vulnerable-function mechanisms of the Distance and Activation relations.

Autonomy

The sense that the source of one's actions lies within the self. Inhibition by obligation or coercion is at the core of attrition in role-type relations.

Competence

The sense of being able to engage effectively with the environment. Chronic stimulation of the POLR directly inhibits competence.

Relatedness

The sense of connection and belonging with others. The "no need for others" stance of the Distance relation blocks the relatedness need and shuts off intrinsic motivation.

Theory Overview

Flow is a state of complete immersion in an activity, definable as the simultaneous heightening of automatic deployment of intellectual strengths (Learning core) and intrinsic energy (Activation core). Flow does not arise in the presence of obligatory motivation, external evaluation, or coerced roles. It is referenced both for the "ignition of intellectual strengths → energy-rising cycle" of the Mirror relation and for the "mutual exclusivity of flow and tedium" of the Tedium relation.

Referenced Relations

Mirror (rising cycle of intellectual immersion and intrinsic energy) Activation (energy ignition → automatic deployment of intellectual strengths) Role (flow does not arise under obligatory motivation) Tedium (flow and tedium are mutually exclusive) Benefactor (joy and tedium do not coexist)

Theory Overview

Bandura argued that the "belief that one can perform a given behavior (self-efficacy)" governs the initiation, persistence, and coping with difficulty of behavior (1977). Self-efficacy and shame/humiliation are directly antagonistic — the principle that the more the POLR is stimulated, the more self-confidence (Leading core) is lost is directly referenced for the Conflict relation mechanism (Bandura 1982). The principle that adaptive self-regulation becomes difficult when anxiety and shame intensify is also referenced for the Supervisor relation.

Referenced Relations

Conflict (POLR → loss of self-confidence and agency) Supervisor (anxiety → difficulty of adaptive self-regulation)

Bandura, A. (1977). Self-efficacy. Psychological Review, 84(2), 191–215. / (1982). Self-efficacy mechanism in human agency. American Psychologist, 37(2), 122–147.

Theory Overview

Yerkes & Dodson discovered that the relationship between arousal and performance follows an inverted U-shape — performance drops when arousal is too low or too high, and peaks at an optimal moderate level of arousal. The principle that prolonged tension from involuntary deployment of latent functions (forced activation of background and adjustment) leads to a state of hyper-arousal beyond the optimal point on the inverted-U curve is referenced for the mechanisms of the Supervisor and Tense Benefactor relations.

Referenced Relations

Supervisor (tension of involuntary latent deployment → Yerkes-Dodson hyper-arousal) Tense Benefactor (chronification of tense deployment)

Psychoanalysis & Depth Psychology

Theory Overview

Freud's theory of sublimation explains the process by which instinctual, impulsive energy is converted into socially acceptable higher-order expression (art, creation, intellectual activity). When depression and projection are strong, impulsive energy is less easily converted into creative output — this is referenced as the psychological foundation of "suppression of Leading-Assimilation (sublimation)" in the Performer relation.

Referenced Relations

Performer (depression and projection → inhibition of sublimation and creative deployment) Kindred (Leading-Assimilation = sublimation and creative self-expression)

Freud, S. (1914). On narcissism. / Various works on defence mechanisms.

Theory Overview

Anna Freud systematized defense mechanisms, classifying them as unconscious protective strategies the ego uses against anxiety and threat. In particular, the linkage between "defensive closure (excluding others, internal withdrawal)" and "social obligation (submission to the superego)" is referenced as the psychological mechanism of the "dual linkage between the Ignoring core (defensive closure) and the Role core (obligation)" in the Distance relation.

Referenced Relations

Distance (linkage between defensive withdrawal and social obligation)

Theory Overview

Adler positioned compensation for inferiority as a basic motivation of human behavior. The compensatory behavior pattern of "being hurt or POLR-stimulated → automatic flight from what one wants to do toward what one can do" is a core concept of Adlerian compensation theory. The exhaustion chain in which the more forced deployment of competence (background core) continues, the more POLR (the unfulfillment of what one really wants to do) accumulates, is also derived from this theory.

Referenced Relations

Conflict (being hurt → automatic flight to what one can do) Quasi-Identity (forced deployment of competence → exhaustion chain of POLR accumulation)

Adler, A. (1927). Understanding Human Nature. Greenberg.

Theory Overview

Jung's individuation refers to the process of integrating elements of the unconscious into consciousness and realizing the true Self. The stability of the persona (social mask) enables surface adaptation but inhibits direct confrontation with internal contradiction (cognitive dissonance) — this forms the foundation of "persona stability vs. introspection conflict" in the Correctional relation. The mechanism by which over-dependence on obligatory roles (Role-Assimilation) weakens as individuation progresses is also referenced for the Mentor relation.

Referenced Relations

Mentor (integration → obligatory output and rationalization weaken) Correctional (cognitive dissonance shakes the persona) Adaptation (persona stability = difficulty of introspection)

Theory Overview

Kohut's self psychology argued that "pride, ego ideal, and orientation to direction" form the core of psychological health. Narcissistic injury and the problems of narcissism are related to the impairment of this orientation toward the ego ideal. Kohut's self psychology is referenced for the mechanism of the Codependency relation, in which the ego ideal of "this is who I want to be" quietly recedes as chronic exhaustion continues.

Referenced Relations

Codependency (chronic exhaustion → erosion of ego ideal and pride) Ideal (activation of pride, ego ideal, and orientation to direction)

Cognitive & Clinical Psychology

Theory Overview

MBCT is a mindfulness-based cognitive therapy developed for the prevention of depressive relapse. As a core concept it uses the contrast between "Doing mode (a coercive mode of mental activity oriented toward problem-solving, evaluation, and goal attainment)" and "Being mode (a mode of open awareness of the present moment)." Doing mode comes to the foreground when belongingness and primary motivation (Suggestive core) are unmet, inducing coercive automatic behavior patterns (background core).

Doing mode

A coercive mode of behavior driven by "doing because one should, doing because one can." The psychological substrate of the background core (habituation, automatic reaction).

Being mode

Open awareness of the present moment. A state that arises naturally when primary motivation and the Suggestive core are fulfilled.

Application Point

When the need to belong is fulfilled, Doing mode recedes — the theoretical basis for "background core suppression" in the Duality relation.

Referenced Relations

Duality (belongingness fulfillment → recession of Doing mode) Conflict (POLR stimulation → flight into compensatory Doing mode) Quasi-Identity (forced deployment of competence = fixation of Doing mode)

Teasdale, J. D., Williams, J. M. G., & Segal, Z. V. (2014). The Mindful Way Workbook. Guilford Press.

Theory Overview

Nolen-Hoeksema empirically demonstrated that "rumination" — repeatedly and passively directing attention to negative emotional states — prolongs and worsens depression (1991). Rumination and depression mutually reinforce each other in a vicious cycle: the deeper the injury and depression, the more deep-layer rumination and worry are induced, and rumination in turn prolongs depression. This is the empirical basis for the exhaustion cycle in the Belonging, Performer, and Tense Beneficiary relations.

Referenced Relations

Belonging (when belongingness functions, deep-layer rumination and worry ease) Performer (depression → exhaustion cycle of rumination and worry) Tense Beneficiary (rumination → vicious cycle of acute exhaustion)

Theory Overview

The DMRS is an observational and rating system for defense mechanisms developed by Perry (1990). "Acting out" — a defense in which internal conflict is directly expressed in behavior — is used in the Conflict relation to explain the pattern of POLR stimulation → compensatory automatic behavior ("flight to what one can do").

Referenced Relations

Conflict (POLR stimulation → Acting-out-style compensatory behavior)

Theory Overview

Prout et al. (2022) empirically validated defense mechanism clusters in a sample of 1,539. In particular, in the "mental inhibition and avoidance" cluster, emotional dissociation/indifference and intellectualization/persona stability were shown to coexist as a single defense cluster. It was also confirmed that "tedium-avoidant behavior (Ignoring-Assimilation) and obligatory output / reaction formation (Role-Assimilation)" belong to the same cluster.

Referenced Relations

Detachment (dissociation/indifference and intellectualization in the same defense cluster) Tedium (tedium/avoidance and reaction formation in the same defense cluster)

Theory Overview

The empirical research of Sedikides & Wildschut (2019) showed that nostalgia is not merely "backward-looking sentimentality about the past" but an adaptive emotion that strengthens the sense of social connection, meaning, and self-continuity. When nostalgia is evoked, an interdependent self-concept is activated (Batcho 2020) — this serves as the empirical basis for the linked mechanism in the Belonging relation: "nostalgia → belongingness → sublimation and creative deployment (Leading-Assimilation)."

Referenced Relations

Belonging (nostalgia → belongingness → rising linkage with sublimation and creative deployment)

Theory Overview

Maslach's burnout syndrome model systematized the way chronic stress produces a three-dimensional state of exhaustion: "emotional exhaustion, depersonalization, and reduced sense of accomplishment." The sequential pattern in which the longer chronic exhaustion continues, the more deep-layer numbness and desensitization (relaxation) accumulate, is referenced as the theoretical foundation of "chronic exhaustion → accumulation of numb calm" in the Codependency and Relaxation relations.

Referenced Relations

Codependency (chronic exhaustion → accumulation of desensitization and numb relaxation) Relaxation (chronic exhaustion quietly accumulates behind relaxation and desensitization)

Humanistic & Growth Psychology

Theory Overview

Maslow's hierarchy of needs presents the order: physiological → safety → belongingness → esteem → self-actualization. Higher-order needs (self-actualization, peak experience) come to the foreground when lower-order needs are fulfilled. Peak experience requires openness, awe, and connection with others, and is fundamentally incompatible with dissociation and indifference — this is the basis for the vulnerable-function aspect of the Detachment and Self-Transcendence relations. The principle that Doing mode recedes when the need to belong is fulfilled is also referenced for the Duality relation, together with Baumeister & Leary and MBCT.

Connection with the Need to Belong

When fulfilled, defensive behavior and Doing mode recede. The basis for "background core suppression" in the Duality relation.

Peak Experience

Requires openness, awe, and connection. Incompatible with dissociation and indifference (the Detachment relation).

Sequence with Critical Introspection

The temporal sequence in the Correctional and Self-Transcendence relations, in which higher-order fulfillment and transcendence arrive after awareness and correction.

Referenced Relations

Duality (belongingness fulfillment → suppression of background core) Detachment (mutual exclusivity of dissociation and peak experience) Self-Transcendence (higher-order fulfillment toward peak experience) Correctional (critical introspection → temporal sequence to peak experience)

Theory Overview

Frankl placed the "will to meaning" — the search for meaning and purpose as a fundamental human motivation — at the core of logotherapy. The state of "able to do but not fulfilled" coexists poorly with "discovery and acceptance of meaning" — this principle is referenced for the mechanism of the Relaxation relation, in which "the sense of meaning recedes the longer expectational deployment continues." The principle that the sense of meaning and orientation toward the ego ideal are sequentially linked is also used for the Compass relation.

Referenced Relations

Compass (sense of meaning → sequential linkage with orientation toward the ego ideal) Relaxation (expectational deployment → loss of insight into the sense of meaning and original craving)

Theory Overview

Rogers placed at the core of humanistic psychology the "actualizing tendency" inherent in human beings — the natural tendency to function in a more complete form. The principle, resonant with Maslow, that peak experience and transcendence require openness, awe, and connection and are fundamentally incompatible with dissociation and indifference (a closed state), is referenced to explain the vulnerable-function dimension of the Self-Transcendence relation.

Referenced Relations

Self-Transcendence (mutual exclusivity of openness and dissociation/indifference)

Theory Overview

Post-Traumatic Growth (PTG), proposed by Tedeschi & Calhoun, refers to the positive transformative process by which one reaches a higher level of psychological functioning than before, after experiences of difficulty, adversity, or trauma. PTG research is referenced for the rising linkage of the Mentor relation, in which the experience of transmitting something from a mentor-like position (Learning-Assimilation) elicits joy, gratitude, and benefactor-like activation, and for the mechanism of the Benefactor relation, in which the deeper the joy of giving becomes, the more the desire for integration and mentor-like transmission is induced.

Referenced Relations

Mentor (integration and mentor transmission → joy, gratitude, benefactor activation) Benefactor (joy of giving → strengthening of the desire for integration and mentor transmission)
