Scientific scope: regulating emotion and acting with flexibility
Emotion regulation refers to processes through which people influence which emotions arise, when those emotions arise, how they unfold, and how they are experienced or expressed. Regulation can concern an anticipated emotional episode, the situation producing it, the allocation of attention, the interpretation of events, or the behavioral and physiological responses that follow. This field studies processes operating within an individual and between people, including the ways one person's behavior changes another person's emotional course. McRae and Gross (2020)
Psychological flexibility concerns the capacity to remain responsive to changing circumstances while pursuing personally meaningful action. It includes shifting attention, relating differently to thoughts and sensations, tolerating unwanted experiences when necessary, and adapting behavior to goals, values, and environmental demands. In the literature, broad psychological flexibility and the more specialized acceptance-and-commitment framework overlap but have different theoretical and measurement traditions. Kashdan and Rottenberg (2010)
Emotion regulation, psychological flexibility, and regulatory flexibility meet at a central problem: choosing an appropriate response to a particular emotional situation. Their research questions differ in emphasis. Emotion regulation investigates the mechanisms that shape emotions; psychological flexibility investigates behavioral adaptation across changing circumstances; regulatory flexibility examines how people detect contextual demands, deploy strategies, and revise their actions after receiving feedback. The cluster connects these literatures while preserving their distinct constructs.
The process model: where emotional responses can change
The process model introduced by James J. Gross classifies regulatory strategies according to their location in the unfolding emotion process. Situation selection alters which events a person encounters; situation modification changes features of an ongoing situation; attentional deployment directs mental resources; cognitive change alters interpretation; and response modulation changes experiential, behavioral, or physiological components once the emotional response is under way. The categories describe families of operations rather than rigid steps that must always occur in sequence. Gross (1998)
Situation selection may involve choosing an environment conducive to concentration or deciding to approach a difficult conversation under more suitable conditions. Situation modification might involve clarifying a misunderstanding, asking for assistance, or creating time for recovery. These approaches influence the conditions under which emotions develop; their usefulness depends on both immediate demands and longer-term costs. Avoidance becomes an important research question when it is persistent, rigid, or incompatible with relevant goals.
Attention and appraisal provide additional routes to regulation. Directing attention toward a task, shifting perspective, and reconsidering the meaning of an event may change the intensity or quality of emotion. Attention can serve protective and constructive purposes, but distraction may also postpone necessary decisions. Cognitive reappraisal can change emotional meaning; it does not require a person to deny an event or to assume every situation is benign.
Response-focused regulation includes changing visible expression, bodily behavior, or the manner in which feelings are communicated. Expressive suppression and the suppression of subjective experience are not interchangeable. A person can conceal an expression while still feeling the emotion strongly. Gross and John's studies of individual differences in reappraisal and suppression connected their habitual use to affective and interpersonal outcomes, although those correlations cannot determine the consequences of every individual episode. Gross and John (2003)
From strategy identification to monitoring and adjustment
The extended process model examines how people recognize a need for emotion regulation, select among strategies, and implement a chosen strategy. Monitoring then informs whether to maintain, modify, or stop the attempt. A strategy may be well selected but poorly implemented, or competently implemented in a situation where another response would serve the person's goals more effectively. This model explains why awareness, decision-making, execution, and feedback should be investigated separately. Gross (2015)
Successful regulation is multidimensional. Investigators can examine changes in self-reported feeling, behavior, social functioning, physiological responses, and goal attainment. These measures sometimes diverge. A quieter outward response can coexist with sustained internal distress; a person may experience strong emotion while handling a demanding task effectively. The chosen outcome therefore determines which aspect of success a study actually measures.
Strategies: reappraisal, acceptance, suppression, and attention
Cognitive reappraisal changes an interpretation before or during an emotional episode. In experiments, researchers may ask participants to reinterpret the meaning of emotional material, take a more detached perspective, or reconsider the consequences of an event. Meta-analytic findings indicate that regulatory strategies can alter emotions, but effectiveness depends on the specific instructions, task, outcome measure, and context. Webb, Miles, and Sheeran (2012)
Acceptance involves allowing an emotion or internal sensation to be present while choosing how to respond. Its practical significance appears when attempts to eliminate an unavoidable internal experience restrict behavior. Acceptance does not demand inaction in the face of preventable harm. It may coexist with practical problem-solving, boundary-setting, and efforts to change external conditions.
Expressive suppression influences how emotion is shown to others. Its consequences can vary by cultural expectations, interpersonal setting, emotional goals, and the demands of a particular role. The distinction between suppressing expression and suppressing experience matters in both laboratory measurement and ordinary language. A universal ranking of strategies would conceal the effects of context, motivation, and timing.
Distraction, attention shifting, rumination, and problem-solving all interact with emotional responses in different ways. A brief shift of attention can reduce immediate burden while a person regains the ability to act; persistent rumination can maintain repetitive negative thinking; practical problem-solving can change the source of distress when the external situation is modifiable. A meta-analysis across clinical presentations found meaningful associations between habitual strategies and symptom levels, with marked variation among strategies and diagnoses. Aldao, Nolen-Hoeksema, and Schweizer (2010)
Regulatory flexibility: sensitivity to context and feedback
Regulatory flexibility is a context-sensitive capacity to deploy a suitable regulatory response and adjust it as circumstances evolve. Its assessment requires attention to environmental demands, a person's repertoire of possible strategies, and responsiveness to the results of attempted regulation. The relevance of a strategy cannot be inferred from its category alone; the immediate situation, values, available resources, and longer-term consequences all matter. Bonanno and Burton (2013)
A person preparing for a stressful examination may benefit from reducing distractions and reframing temporary uncertainty. During an urgent practical problem, taking action to change the situation may be more effective than focusing exclusively on internal experience. In an uncontrollable loss, acknowledgment of grief and seeking interpersonal support may serve goals that problem-solving cannot accomplish. These examples describe distinct situational requirements rather than prescribing a single universal strategy.
The ability to switch strategies also has limits. Switching too often can interrupt learning and sustained action, while continuing an ineffective approach can amplify difficulties. Good regulation often means noticing the difference between temporary emotional discomfort and persistent failure to meet a meaningful goal. Research on flexibility must therefore consider timing, ecological validity, repeated measurements, and whether change improves the outcomes that matter to the person.
Psychological flexibility, values, and experiential avoidance
Psychological flexibility is prominent in contextual behavioral science and acceptance and commitment therapy (ACT). The framework describes interconnected processes including acceptance, cognitive defusion, present-moment awareness, self-as-context, values, and committed action. These processes offer an organized way to study responses to thoughts and feelings and their relation to flexible behavior. Their usefulness as a conceptual framework should be evaluated separately from evidence that a particular clinical intervention works for a particular diagnosis.
Experiential avoidance refers to attempts to escape, control, or reduce unwanted private experiences, often involving emotions, bodily sensations, memories, or thoughts. Avoidance can be useful when it protects a person from an immediate danger or prevents unnecessary overload. Persistent attempts to avoid normal internal experiences become a concern when they dominate decisions and restrict valued activities. The relevant research question is the function and cost of a pattern in context.
Cognitive defusion describes practices that change the functional relationship between a thought and subsequent action. A person may notice a self-critical thought as a mental event, while still evaluating its informational value and deciding what to do. This process differs from automatically arguing with every thought or treating every thought as true. Values and committed action concern the direction and continuity of behavior under variable emotional circumstances.
The broader flexibility literature discusses adaptation to situational change and the capacity to balance competing needs. Review-level evidence associates psychological flexibility with aspects of health and adjustment. These associations integrate several methodological traditions, so strong mechanistic and treatment-specific claims require more narrowly designed studies. Kashdan and Rottenberg (2010)
Emotion dysregulation and transdiagnostic mental health
Emotion dysregulation describes difficulties recognizing, understanding, accepting, modulating, or responding effectively to emotions. The term may refer to problems with emotional clarity, impulsive behavior under distress, limited access to effective strategies, or difficulty pursuing goals during intense feeling. It is a descriptive clinical and research construct, not an independent diagnosis. A broad definition should remain distinguishable from symptom profiles in ADHD, mood disorders, trauma-related disorders, and other conditions.
Emotion regulation patterns are associated with depression, anxiety, eating-related symptoms, substance problems, and other forms of distress. Meta-analytic correlations are informative about shared vulnerabilities and possible maintaining processes, but observational associations do not establish that a specific strategy causes a particular disorder. The patterns can also be shaped by socioeconomic stress, interpersonal adversity, sleep, and environmental constraints. Aldao, Nolen-Hoeksema, and Schweizer (2010)
Clinical interpretation should separate the intensity of an emotion from the person's ability to respond to it, and should consider duration, impairment, situational context, safety, development, and cultural meaning. Strong emotion in response to loss, danger, injustice, or major change can be coherent with a person's circumstances. Screening questionnaires may guide further questions, while formal diagnoses require appropriate professional evaluation of the broader clinical picture.
Measuring regulation and flexibility
The Emotion Regulation Questionnaire (ERQ) assesses habitual cognitive reappraisal and expressive suppression. It was developed to study differences in the frequency with which people report using these approaches. Its scales provide a limited window into two strategies, and their meaning depends on the language, population, and study design. The ERQ is not a diagnosis of dysregulation or an assessment of all regulatory capacities. Gross and John (2003)
The Difficulties in Emotion Regulation Scale (DERS) examines several dimensions of perceived difficulty, including emotional clarity, acceptance, impulse control, access to strategies, and goal-directed functioning under distress. The original validation provided an influential multidimensional framework; subsequent studies have evaluated its structure and shorter forms across populations. Scores summarize responses to items and must be interpreted within the limits of the instrument and study population. Gratz and Roemer (2004)
The Acceptance and Action Questionnaire–II (AAQ-II) has often been used as an index of experiential avoidance or psychological inflexibility. Its psychometric development is established, and later research raised questions about its ability to distinguish this intended construct from general psychological distress. Research designs should make this dispute explicit rather than treating every self-report measure as interchangeable. Bond and colleagues (2011) Tyndall and colleagues (2019)
The Personalized Psychological Flexibility Index (PPFI) represents another approach to measuring contextual responses to discomfort. The field also uses repeated daily sampling, behavioral tasks, observer reports, and measures focused on contextual variation. These approaches answer different questions. A useful assessment asks which capacities or patterns a measure captures, what it omits, and whether its results remain valid beyond the specific sample in which it was tested.
Development, co-regulation, and interpersonal contexts
Emotion regulation develops through interactions among emerging cognitive abilities, temperament, physiological maturation, relationships, and learning opportunities. In childhood, caregivers contribute through modeling, support, emotion-related discussion, and the emotional climate of family life. The balance between external co-regulation and independent regulation changes with development, although supportive relationships remain significant during adolescence and adulthood. Morris and colleagues (2007)
Co-regulation describes ways that another person helps shape the organization, intensity, or interpretation of emotion through presence, communication, shared routines, and responsiveness. It can occur in caregiving, intimate partnerships, friendships, and therapeutic settings. It requires respect for the other person's agency and needs, and its effects depend on the quality of the relationship and the situation.
During adolescence, autonomy, peer relationships, social evaluation, and changing cognitive demands influence the regulation strategies that are available and used. Patterns also vary among individuals, including neurodivergent people whose sensory, communication, or executive-function profiles shape emotion-related experience. Appropriate support should attend to personal strengths, environment, developmental level, and individual needs rather than assuming a uniform profile.
Everyday practice, environmental support, and clinical decisions
Research-informed skills begin with recognizing the emotion, identifying its source, and clarifying the goal of regulation. A person can then consider whether a situation should be changed, attention redirected, an interpretation reviewed, a difficult feeling accepted, or interpersonal support requested. Evaluating the result and choosing again when needed connects individual strategies to broader regulatory flexibility. These steps describe a flexible decision framework rather than a fixed intervention protocol.
Self-soothing and grounding may help people orient attention, reduce immediate demands, or tolerate temporary distress. Their effects depend on the person and the underlying problem. Strong bodily sensations can have medical as well as psychological causes; persistent or escalating difficulties, risk of self-harm, severe functional impairment, or rapidly changing mental states call for qualified professional assessment and appropriate urgent support.
Evidence-based psychological treatments, including cognitive behavioral approaches, dialectical behavior therapy, and acceptance and commitment therapy, teach particular skills in structured clinical contexts. The efficacy of a treatment depends on the problem addressed, the protocol, comparison condition, study population, and measured outcome. Clinical treatment evidence must not be inferred solely from a general claim that emotion regulation matters for well-being.
Emotion regulation in digital environments and the Artificial Era
Digital environments can alter emotional demands through persistent notifications, social comparison, attention capture, and interactions that occur across distance. People may also use journals, guided exercises, digital interventions, or conversational AI systems when seeking support. These technologies differ in their mechanisms, evidence base, accountability, and risk. The general regulation framework developed here is relevant to these contexts, while system-specific benefits, limitations, and safety questions belong to specialized digital and AI mental-health research.
The Artificial Era provides a broader context in which human attention, agency, relational practices, and interaction with artificial systems are changing. For this scientific chapter, psychological claims about users depend on independently studied behavior and outcomes. Philosophical accounts of artificial subjectivity and nonbiological reason require their own explicit attribution and conceptual analysis, separate from clinical evidence regarding human emotion regulation.
Evidence quality, methodological limits, and research priorities
The evidence base includes experimental manipulations, cross-sectional associations, longitudinal research, psychometric validation, clinical trials, and meta-analyses. Each design supports different inferences. Laboratory reappraisal tasks can establish short-term effects under controlled instructions, while longitudinal or daily-life studies address strategy selection and outcomes in natural settings. Self-report scales can reveal perceived patterns but are susceptible to recall effects, response biases, and construct overlap.
Important research priorities include better ecological measurement of strategy switching, causal tests of regulatory flexibility, cross-cultural measurement invariance, developmental comparisons, social co-regulation, and the distinction between improving a measured feeling and improving valued functioning. The scientific picture grows more informative when interventions and mechanisms are evaluated with multiple outcomes, explicit comparison conditions, adequate follow-up, and transparent methodological reporting.
