temperament
Enable an AI agent to record a person's characteristic patterns of emotional, attentional and behavioral response, judge how well those patterns are supported, and identify suitable accommodations without treating temperament as destiny or diagnosis.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Enable an AI agent to record a person's characteristic patterns of emotional, attentional and behavioral response, judge how well those patterns are supported, and identify suitable accommodations without treating temperament as destiny or diagnosis.
A relatively stable, biologically grounded pattern of reactivity and self-regulation that appears early in life and organizes how an individual typically approaches, withdraws from, and recovers from stimulation, distinct from later-acquired personality traits and from momentary mood.
It can be Construct a dimensional temperament profile with explicit context, time period and uncertainty.; Compare reports and observations while retaining disagreements between informants and settings.; Distinguish a possible enduring tendency from a temporary response and identify observations needed to test it.; Suggest reversible adjustments to stimulation, transitions, pacing or interaction style based on observed fit and the person's preferences.; Reassess a profile as development, circumstances or contradictory evidence change its interpretation..
Distinguishing features
A temperament attribution requires evidence of a characteristic tendency; one angry, anxious or energetic episode establishes only an observed state.
A temperament description concerns how readily, strongly or persistently a person responds, rather than what the person believes, values or intends.
A repeated behavior does not establish temperament until situational demands, learned routines and temporary conditions have been considered.
A temperament tendency can be described without asserting disorder, impairment, moral worth or a fixed future outcome.
A temperament profile identifies dimensions and contextual qualifications; a type label alone does not provide enough information to recognize the pattern.
Scope
+ Characteristic thresholds, intensity and recovery patterns of emotional responses
+ Typical activity, approach, withdrawal and adaptation to novelty
+ Attentional persistence, shifting and regulation of initial responses
+ Variation in temperament expression across settings and developmental periods
+ Evidence supporting a tendency and practical fit between tendencies and situational demands
- A person's current mood or individual emotional episode
- The full personality profile, including values, identity and personal commitments
- Psychiatric diagnoses, symptoms and clinical treatment decisions
- Learned skills, habits and coping strategies considered independently of temperament
- Genetic, neurological or physiological mechanisms proposed to explain temperament
- Musical tuning systems also called temperaments
Characteristics
- Response activation threshold
- Instrument-specific score or described stimulus conditions sufficient to elicit a response; no universal unit assumed Distinguishes readiness to respond from the intensity of a response once activated.
- Emotional response intensity
- Named rating scale or anchored observational rating, separately identified by emotion and context Supports comparison of response strength without assuming that all emotions follow the same pattern.
- Recovery duration
- Seconds or minutes to a defined baseline, or an explicitly named rating scale Distinguishes a brief strong reaction from a sustained response and informs pacing.
- Novelty response tendency
- Approach, withdrawal, mixed or insufficient evidence, with the kind of novelty specified Makes unfamiliar social situations distinguishable from unfamiliar objects, tasks or environments.
- Typical activity level
- Instrument-specific score or observed movement frequency and duration within a defined setting Helps assess fit with movement demands while keeping activity distinct from motivation or compliance.
- Attention persistence and shifting
- Separate task-specific duration, shift latency or named scale scores Distinguishes staying engaged from the ability to redirect attention when circumstances change.
- Response regulation
- Named measure or anchored observation of pausing, redirecting or modulating a response under stated demands Separates initial reactivity from what happens after regulation becomes possible.
- Cross-context expression
- Tendency linked to settings where it is observed, absent, reversed or unassessed Prevents observations in one environment from becoming unrestricted claims about the person.
- Profile assessment state
- Provisional, supported within stated bounds, contested or awaiting reassessment Controls how strongly an agent may rely on the profile and when it should seek further evidence.

Drafted structure
Bundle to layer to finding to question, as the second pass will find it: 5 bundles · 9 layers · 16 findings · 26 questions.
Reactivity and recovery The conditions under which emotional responses arise, their strength and their course.
A temperament model must distinguish ease of activation, response intensity and recovery instead of collapsing them into labels such as sensitive or difficult.
Response activation
Characteristic elicitors, thresholds and intensity of emotional responses.
Emotional reactivity pattern
Record a candidate pattern separately for relevant emotions, with eliciting conditions and observable indicators.
- Which situations elicit the response, and what observations distinguish its activation threshold from its intensity? measurement
- Does the evidence support this tendency across occasions, or only during a particular episode or temporary condition? boundary
Response course
Persistence and recovery after emotional activation.
Recovery pattern
Record how a response subsides, what counts as recovery and whether support was involved.
- How is return to baseline defined, and how long does it take under the observed conditions? measurement
- How does recovery differ with reassurance, reduced stimulation, solitude or other support? measurement
Engagement and adaptation Characteristic activity and engagement with unfamiliar or changing situations.
Initial approach, typical activity and adaptation after exposure can differ and lead to different practical accommodations.
Activity and approach
Typical movement and initial orientation toward novelty.
Initial engagement pattern
Record activity and approach or withdrawal as distinct tendencies within specified situations.
- What activity level is typical when movement is freely permitted, and how does it differ under imposed constraints? measurement
- Does the person approach or withdraw from unfamiliar people, tasks and environments in the same way? boundary
Adaptation after change
How engagement changes after initial exposure or a disrupted routine.
Adaptation trajectory
Record the course of adjustment separately from the first reaction to a change.
- Across repeated exposure, how does engagement change, and what marks adjustment to the new situation? measurement
- Would advance notice, gradual introduction or a familiar companion improve observed comfort and participation? action
Attention and regulation Characteristic attentional engagement and modulation of responses.
An agent must distinguish initial impulses from attention and regulation, while avoiding unsupported judgments about ability or willingness.
Attentional patterns
Persistence, distractibility and shifting under specified task conditions.
Persistence and shifting
Record sustained engagement and redirection separately, with interest, difficulty and interruptions identified.
- How long does engagement persist, and how readily does attention shift when a change is requested or needed? measurement
- Could the observed pattern be better explained by task interest, skill, fatigue or environmental distraction? boundary
Response modulation
The observed capacity and conditions for pausing or modifying a response.
Regulation under demand
Record how initial responses are modified and distinguish independent regulation from externally supported regulation.
- Under what demands can the person pause, redirect or reduce a response, and what assistance is present? measurement
- Which parts of the observed regulation are attributed to temperament by the chosen framework, and which are learned strategies or situational supports? boundary
Profile validity and fit The evidence, developmental bounds and practical implications of a temperament profile.
Temperament descriptions require limits on generalization and a way to assess accommodations without turning tendencies into fixed prescriptions.
Evidence and development
How the profile was established and the periods and settings it represents.
Bounded temperament attribution
Record the assessment framework, informants, observations, age and dates, including conflicting evidence and reassessment needs.
- Which framework, instrument, informants and repeated observations support each attributed tendency? provenance
- What age range, time period and settings does the evidence cover, and where do reports disagree? boundary
- What developmental change or contradictory observation would trigger reassessment? action
Situational fit
How a tendency interacts with environmental demands and the person's preferences.
Accommodation and review
Record specific mismatches, proposed adjustments and outcomes without assigning inherent goodness or badness to a tendency.
- Which specific demand appears to conflict with the observed tendency, and what evidence links that mismatch to difficulty? measurement
- Which reversible adjustment accords with the person's preferences, and what outcome would justify retaining or revising it? action
- Which proposed decisions exceed what this temperament evidence can justify? boundary
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
A model that cannot be lined up against existing standards, identifiers and practice cannot be adopted by anyone who already uses them.
Reported evidence
Findings from the breadth pass, kept separate from the structural claims.
Kinds and varieties
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- Hippocratic-Galenic four temperaments (sanguine, choleric, melancholic, phlegmatic)
- Infant and child temperament dimensions (activity, approach-withdrawal, intensity, mood, adaptability, persistence, threshold, rhythmicity, distractibility; Thomas and Chess easy / difficult / slow-to-warm-up)
- Rothbart reactive and regulatory temperament (extraversion/surgency, negative affectivity, effortful control; plus affiliation in some models)
- Buss and Plomin EAS (emotionality, activity, sociability, later shyness)
- Cloninger psychobiological temperament (novelty seeking, harm avoidance, reward dependence, persistence)
- Keirsey temperament sorter types (artisan, guardian, idealist, rational)
- Animal and livestock temperament (flightiness, docility, fearfulness, reactivity to handling)
- Musical temperament (tuning systems: equal, just, meantone, well, Pythagorean) - a different sense of the same word
- Which of these kinds and varieties hold for the sense of temperament this model covers, and on what evidence? provenance
Identifiers and schemes
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- Wikidata - Q192821 (temperament as personality disposition); Q544859 (musical temperament) - Two distinct items; psychological and musical senses must not be collapsed.
- MeSH - D013686 Temperament - NLM Medical Subject Heading for the psychological/behavioral sense.
- APA Thesaurus / PsycINFO - Temperament - Controlled vocabulary term in psychology indexing.
- Which of these identifiers and schemes hold for the sense of temperament this model covers, and on what evidence? provenance
Standards and regulation
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- No ISO, IEC, or statutory code governs human temperament as a construct. Clinical use is constrained by ordinary professional and research-ethics rules (APA Ethical Principles; Declaration of Helsinki for research; local medical-device and IVD rules only if a temperament scale is sold as a diagnostic device, which standard questionnaires generally are not).
- Livestock: temperament or docility is scored under breed-society and welfare schemes (e.g. Beef Improvement Federation guidelines in the US; various EU animal-welfare directives address handling stress, not a named temperament standard).
- Musical temperament (the other sense) is specified in tuning practice and in some instrument and MIDI/tuning standards (e.g. 12-tone equal temperament as A4=440 Hz under ISO 16), which do not apply to the psychological sense.
- Which of these standards and regulation hold for the sense of temperament this model covers, and on what evidence? provenance
Real-world use
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- Pediatric and early-education assessment: caregivers complete questionnaires (IBQ-R, ECBQ, CBQ, lab-TAB) so clinicians can match environment to the child rather than treat temperament as pathology.
- Adult personality and psychiatry: Cloninger TCI/TCI-R and related inventories used in research and some clinical formulation to separate temperament from character and to discuss treatment response.
- Occupational and popular psychology: Keirsey and four-humour typologies used in coaching and self-help; these are weakly aligned with developmental temperament science.
- Animal breeding and stockmanship: chute scores, flight-speed, and crush scores recorded on cattle, horses, and dogs as heritable welfare and safety traits.
- Music (homonym): keyboard and ensemble tuning (equal vs historical temperaments) in performance practice.
- Which of these real-world use hold for the sense of temperament this model covers, and on what evidence? provenance
Typical measurements
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- Dimension score on a standardized temperament questionnaire (e.g. CBQ extraversion/surgency, negative affectivity, effortful control) - Likert-scale means typically near the scale midpoint in unselected samples; published T-scores or z-scores often ~30-70 - instrument-specific scale points or standardized T/z
- Observer-rated activity level / motor activity - task- and age-dependent; laboratory coding often 1-7 or 1-9 Likert - ordinal rating or actigraphy counts per minute
- Behavioral inhibition / latency to approach a novel object or person - seconds to minutes in laboratory paradigms (Kagan-style) - s
- Heritability of major temperament dimensions (twin/adoption studies) - approximately 0.20-0.60 depending on trait and age - dimensionless (h²)
- Livestock flight speed / chute exit velocity - on the order of 0.5-4 m/s for cattle, highly setup-dependent - m/s
- Which of these typical measurements hold for the sense of temperament this model covers, and on what evidence? provenance
Failure modes and hazards
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- Mistaking temperament for disorder: high negative affectivity or low effortful control labeled as ADHD, anxiety disorder, or 'difficult child' without checking goodness-of-fit or developmental norms.
- Reification of popular types (four humours, Keirsey) as if they were validated clinical diagnoses.
- Cultural and rater bias: parent reports and teacher reports diverge; 'difficult' is partly a fit between child and setting.
- Low temporal stability of some dimensions across infancy; over-interpreting a single early score.
- In animals: highly reactive temperament increases injury risk to handlers and to the animal during restraint; selecting only for docility can trade off against other functional traits.
- Homonym collision: musical 'temperament' retrieved or tagged as if it were a psychological construct (and the reverse).
- Which of these failure modes and hazards hold for the sense of temperament this model covers, and on what evidence? provenance
Regional variation
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- English 'temperament' in psychology is close to German Temperament and French tempérament, but everyday use in some languages collapses temperament with character, mood, or 'temper' (anger).
- East Asian developmental research often emphasizes regulatory/effortful-control and 'inhibition to the unfamiliar' with different social valuation than North American extraversion/surgency norms.
- Four-humour typology remains more visible in continental European popular psychology and in Unani/Greco-Arabic medical heritage than in anglophone academic temperament science.
- Livestock temperament scoring systems differ by country and breed society (US BIF chute score vs Australian flight-time programs vs European welfare scoring).
- Musical temperament practice varies by repertoire and region (modern equal temperament vs circulating well-temperaments in historically informed European performance).
- Which of these regional variation hold for the sense of temperament this model covers, and on what evidence? provenance
Neighbouring kinds and how to tell them apart
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- personality - Personality includes temperament plus character, values, skills, and life-story; temperament is the earlier, more biological core. Test: present in infancy, higher heritability, and measurable as reactivity/regulation rather than as beliefs or roles.
- character (Cloninger) - Character (self-directedness, cooperativeness, self-transcendence) is treated as later-developing and more culturally shaped; temperament dimensions are the heritable response biases. Test: TCI subscale family and developmental timing.
- mood / affect episode - Mood is a time-limited state; temperament is a trait-like baseline of reactivity. Test: duration and return to baseline versus a stable rank-order across situations.
- temper (anger / 'losing one's temper') - Colloquial 'temper' is anger expression; scientific temperament is a multi-dimensional profile. Test: whether the construct includes approach, activity, and regulation, not only irritability.
- personality disorder - Disorder requires clinically significant impairment and diagnostic criteria (DSM/ICD); extreme temperament is not by itself a disorder. Test: distress, dysfunction, and criterion sets rather than questionnaire elevation alone.
- musical temperament (tuning) - A system for distributing interval error across a scale (equal, meantone, well). Test: the object is a pitch system or instrument, not an organism's behavior.
- tempering (metallurgy / glass / chocolate) - A heat or process treatment that changes material microstructure. Test: material process, not a behavioral trait.
- Which of these neighbouring kinds and how to tell them apart hold for the sense of temperament this model covers, and on what evidence? provenance

What the second pass must settle
- Does this registry entry intend human psychological temperament only, or also animal temperament or another meaning?
- Which temperament framework and age-specific instruments should anchor the dimensions, and which dimensions cannot be compared across frameworks?
- What duration, repetition and diversity of settings are sufficient to support a characteristic tendency at different developmental stages?
- How should self-report, caregiver report and direct observation be reconciled when cultural expectations or situational differences produce disagreement?
- Where should this catalogue place the boundary between temperament, broader personality and learned regulation, particularly when their measures overlap?
