The ability to manage and modify your emotional responses. Includes reappraisal, acceptance, and distraction. Central to EQ, ADHD, and autism.

A personality preference for lower stimulation environments. Introverts recharge through solitude and deep focus, prefer small groups over large parties, and think before speaking.

A relatively stable pattern of thoughts, feelings, and behaviors that distinguishes one person from another. Traits are continuous dimensions (not categories) measured on a spectrum.

A person who falls near the middle of the introversion-extraversion spectrum, displaying both introverted and extroverted behaviors depending on context. Most people (60-70%) are ambiverts.

Three socially aversive personality traits: Narcissism (grandiosity, entitlement), Machiavellianism (manipulation, cynicism), and Psychopathy (callousness, impulsivity). Present to varying degrees in the general population.

The scientific framework behind the Big Five personality test. Developed through decades of factor analysis, identifying five broad dimensions that account for most of the variance in human personality.

A personality trait found in 15-20% of the population, characterized by deeper sensory processing, emotional sensitivity, and heightened responsiveness to stimuli. Identified by Elaine Aron (1996).

A persistent pattern of doubting your accomplishments and fearing being exposed as a "fraud" despite evidence of competence. Affects an estimated 70% of people at some point.

The belief that abilities and intelligence can be developed through effort, learning, and persistence — versus a "fixed mindset" that sees traits as unchangeable. Coined by Carol Dweck (2006).

Natural variation in brain function affecting how people think, learn, and process information. Includes ADHD, autism, dyslexia, dyspraxia, and other neurological differences.

A set of cognitive processes that manage, control, and regulate other cognitive abilities: planning, working memory, attention, inhibition, and cognitive flexibility. Central to ADHD.

Consciously or unconsciously suppressing neurodivergent behaviors and mimicking neurotypical ones to fit in socially. Common in autism and ADHD, especially in women.

Repetitive movements, sounds, or fidgeting that regulate sensory input and emotions. Common in autism and ADHD. Examples: rocking, hand-flapping, clicking pens, humming.

A state of chronic exhaustion, loss of skills, and reduced tolerance to stimuli resulting from prolonged masking and sensory/social overload. Different from occupational burnout.

An intense state of concentrated attention on a single activity, often lasting hours. Common in ADHD and autism. A "superpower" when channeled, a challenge when it locks onto non-priorities.

How the brain receives, organizes, and responds to sensory input (sight, sound, touch, smell, taste, proprioception, vestibular). Differences in sensory processing are central to autism and HSP.

Extreme emotional pain triggered by perceived rejection or criticism. Common in ADHD — not a formal diagnosis but a widely recognized experience. Can feel like physical pain.

Innate behavioral tendencies present from birth — the biological foundation of personality. Includes traits like activity level, emotional reactivity, sociability, and attention span.

Difficulty perceiving time passage accurately. Common in ADHD — hours feel like minutes, deadlines sneak up, and "5 more minutes" becomes 2 hours.

A brain chemical involved in reward, motivation, attention, and pleasure. ADHD brains have lower baseline dopamine, driving sensation-seeking, impulsivity, and difficulty with non-rewarding tasks.

A metaphor for limited energy in chronic illness and neurodivergence. Each activity costs "spoons" (energy units). When you run out, you can't function — no matter how much willpower you apply.

A person who is both intellectually gifted AND has a disability or neurodivergence (ADHD, autism, dyslexia). The giftedness can mask the disability and vice versa, making both harder to identify.

A theory of autism proposing that autistic brains concentrate attention on fewer things but more intensely — a "single-channel" processing style versus the neurotypical "multi-channel" approach.

Difficulty identifying and describing your own emotions. Affects ~10% of the general population and ~50% of autistic people. Not the absence of emotions — the inability to label them.

An autism profile characterized by extreme avoidance of everyday demands and expectations. Not defiance — an anxiety-driven nervous system response to perceived loss of autonomy.

The sense of your internal body state — hunger, thirst, temperature, heart rate, bladder fullness, fatigue. Many neurodivergent people have differences in interoception, leading to missed body signals.

The framework that neurological differences (ADHD, autism, dyslexia, etc.) are natural human variation — not defects to be cured. Advocates for accommodation and acceptance rather than normalization.

Working alongside another person (physically or virtually) to help initiate and sustain focus. Common ADHD strategy — the presence of another person provides external accountability that the ADHD brain lacks internally.

The avoidance of tasks or requests — ranging from normal procrastination to the extreme PDA profile in autism. Understanding the cause (anxiety vs. boredom vs. executive dysfunction) determines the solution.

Thinking about your own thinking — awareness of your cognitive processes, strengths, weaknesses, and learning strategies.

The tendency for people with low competence to overestimate their ability, while experts tend to underestimate theirs. Results from lacking the knowledge to recognize gaps.

Treating yourself with kindness during failures and struggles, rather than harsh self-criticism. Predicts resilience, well-being, and lower anxiety better than self-esteem.

The belief that abilities are static and unchangeable. Leads to avoidance of challenges, giving up easily, and viewing effort as futile.

The ability to recover from difficulties and adapt to adversity. A function of low Neuroticism, high Conscientiousness, and high Agreeableness (support-seeking).

A state of optimal psychological functioning beyond just the absence of mental illness. Includes engagement, purpose, relationships, accomplishment, and positive emotion.

Two paths to happiness: Hedonic (pleasure, positive feelings) vs. Eudaimonic (meaning, self-actualization). Eudaimonic well-being predicts life satisfaction better long-term.

Your overall evaluation of whether your life is meeting your values and goals. The cognitive component of well-being (vs. emotional well-being).

A measure of how consistent a test's results are when the same person takes it again. High reliability (0.70+) means you'll get similar results each time.

Whether a test measures what it claims to measure. A valid personality test actually predicts real-world outcomes like job performance, relationship satisfaction, or mental health.

A response format used in personality tests where you rate agreement on a scale (e.g., "Strongly Disagree" to "Strongly Agree"). Named after psychologist Rensis Likert (1932).

A standardized, scientifically designed assessment that measures psychological attributes — personality traits, cognitive abilities, aptitudes, or attitudes — in a reliable and valid way.

A statistic measuring internal consistency — how closely related a set of test items are as a group. Values above 0.70 indicate acceptable reliability for personality scales.

A statistical pattern where most values cluster around the average, with fewer values at the extremes. Personality traits follow this pattern — most people score near the middle.

Your ranking compared to a reference population. A 72nd percentile Extraversion score means you're more extraverted than 72% of people. Used in Big Five and other continuous-scale tests.

A statistical method that identifies clusters of correlated variables. The Big Five personality traits were discovered through factor analysis of thousands of personality-describing words.

A theoretical concept that cannot be directly observed but is inferred from measurable behaviors. Examples: intelligence, personality traits, emotional intelligence, motivation.

A measure of how strong a relationship or difference is in research. In personality science, effect sizes show how much a trait actually predicts real-world outcomes.

The tendency for test-takers to answer in systematic ways that don't reflect their true personality: social desirability, acquiescence, extreme responding.

Whether a test appears to measure what it claims to measure — from the test-taker's perspective. High face validity = "these questions make sense for what they're measuring."

The reference population against which your test scores are compared. Your Big Five percentile scores are calculated relative to the norm group's distribution.

Optimizing content to be selected as the answer by AI systems (ChatGPT, Perplexity, Google AI Overviews) rather than just ranking in traditional search.

Experience, Expertise, Authoritativeness, Trustworthiness — Google's framework for content quality evaluation. Critical for health and psychology content.

A statistical framework for understanding how test-takers respond to individual items based on their ability level. Modern alternative to classical test theory.

The inconsistency in test scores resulting from imperfect measurement. Every personality test has measurement error — your score is an estimate, not a perfect measure.

The extent to which a test improves prediction beyond what's already predictable from other sources. Does this test add new information?

Whether a test's scores correlate with real-world outcomes it's supposed to predict. The ultimate measure of a test's usefulness.

Whether a test actually measures the theoretical construct it claims to measure. Does the test measure the real trait, or something else by coincidence?

Whether a test's items adequately represent the entire content domain of the construct. Do the questions cover all aspects of what you're trying to measure?

Whether a test's current scores predict future outcomes. The ultimate measure of practical utility — does this test help forecast what will happen later?

Whether a test's scores correlate with current outcomes or other established measures of the same construct. Validity measured at the same time, not in the future.

Whether a test produces consistent scores when the same person takes it twice. Measures temporal stability of the construct.

Whether a test's items correlate with each other, indicating they measure the same underlying construct. Measured with Cronbach's alpha or similar indices.

A statistical measure of internal consistency reliability. Values range 0-1; α=0.70-0.90 is ideal for personality tests. Indicates whether scale items correlate with each other.

A statistic estimating how much an individual's observed test score is likely to vary from their "true" score due to measurement error. Expressed in the same units as the test score.

A psychometric phenomenon where a test item behaves differently across demographic groups (gender, culture, language) holding the underlying trait constant. A key fairness check.

A cognitive bias where overall impression of a person influences ratings of their specific traits. High Halo causes traits to correlate artificially in observer ratings.

The tendency to accept vague, general personality descriptions as uniquely accurate. Named after P.T. Barnum and demonstrated by Bertram Forer (1949).

A set of test items designed to detect respondents who answer in a way that makes them look good, rather than honestly. Used to flag results for cautious interpretation.

Two scoring approaches: ipsative compares your traits to each other (within-person); normative compares your traits to a population. Each answers a different question.

The degree of match between a person's personality, values, and interests and their work environment. Higher fit predicts greater job satisfaction, performance, and retention.

A stable pattern of preferences for certain types of work activities, environments, and outcomes. Measured by assessments like RIASEC to guide career decisions.

An occupational phenomenon (WHO, ICD-11) characterized by emotional exhaustion, depersonalization (cynicism), and reduced personal accomplishment resulting from chronic workplace stress.

A mental state of complete absorption in an activity, where time seems to disappear and performance peaks. Identified by Mihaly Csikszentmihalyi (1990).

A motivational framework identifying three universal psychological needs: Autonomy (choice), Competence (mastery), and Relatedness (connection). When met, people thrive.

A self-concept consisting of values, motives, and competencies that you would not give up when forced to make a career choice. Identified by Edgar Schein (1978). There are 8 career anchors.

A Japanese concept meaning "reason for being" — the intersection of what you love, what you're good at, what the world needs, and what you can be paid for.

A strategic shift to a different career using transferable skills, rather than starting over from scratch. Unlike a career change, a pivot leverages what you already have.

Skills that apply across industries and roles: communication, problem-solving, leadership, project management, data analysis, and emotional intelligence.

Proactively reshaping your job to better fit your strengths, values, and interests — changing tasks, relationships, or perceptions without changing your formal role.

Doing only the minimum requirements of your job, without going "above and beyond." A response to burnout and overwork culture, often driven by personality-career mismatch.

A shared belief that the team is safe for interpersonal risk-taking — speaking up, admitting mistakes, and asking questions without fear of punishment. Key to high-performing teams.

Your personal ranking of what matters most: security, freedom, creativity, family, achievement, helping others. Values conflicts cause the deepest career dissatisfaction.

John Holland's theory that career satisfaction and stability depend on the match between your personality type and your work environment's type. Congruence predicts satisfaction (r=0.28).

Your ideal future career state — what you want to achieve, become, or accomplish. Aspirations differ from interests: you might be interested in programming but aspire to leadership.

A critical distinction: ability (what you can do) and interest (what you enjoy doing) don't always align. Career satisfaction requires matching BOTH, not just one.

The grouping of careers that share common RIASEC codes or trait profiles. People successfully working in one cluster often thrive in similar-coded jobs.

The extent to which you're satisfied with your work — a function of person-job fit, values alignment, relationships, and growth opportunities.

The degree of emotional investment and effort you put into work. More than just satisfaction — it's about being energized, committed, and motivated.

Long-term evaluation of your entire career path — whether your career aligns with your values, aspirations, and identity. Broader than job satisfaction.

The likelihood of quitting your job in the near future. A strong predictor of actual turnover and the first sign that a workplace has a problem.

Four patterns of relating in relationships — Secure, Anxious, Avoidant, and Fearful-Avoidant — developed in childhood and affecting adult romantic and interpersonal bonds.

Five ways people express and receive love: Words of Affirmation, Acts of Service, Receiving Gifts, Quality Time, and Physical Touch. Developed by Gary Chapman (1992).

A destructive relationship cycle where an anxiously attached partner pursues connection while an avoidant partner withdraws. The more one chases, the more the other retreats.

Overwhelming someone with excessive affection, attention, and gifts early in a relationship to gain control. Often associated with narcissistic personality patterns.

A pattern of excessive emotional reliance on a partner, losing your identity and needs to manage theirs. Often develops from childhood with addicted or emotionally unavailable parents.

Managing your emotions as part of your job requirements (service workers smiling despite abuse) or managing others' emotions in relationships (the "default therapist" in a partnership).

Personal limits that define what you will and won't accept in relationships and interactions. Healthy boundaries protect your energy, time, and emotional wellbeing.

A manipulation tactic where someone makes you doubt your own perception, memory, and sanity. Named after the 1944 film "Gaslight." Common in narcissistic abuse patterns.
