Personality: Self concept · Personality testing · Theories · Mind-body problem

In psychology, temperament refers to those aspects of an individual's personality, such as introversion or extroversion, that are often regarded as innate rather than learnt. A great many classificatory schemes for temperament have been developed; none, though, has achieved general consensus in academia.[1]

Historically, the concept of temperament was part of the theory of the four humours, with their corresponding four temperaments. The concept played an important part in pre-modern psychology, and was explored by philosophers such as Immanuel Kant and Hermann Lotze. David W. Keirsey also drew upon the early models of temperament when developing the Keirsey Temperament Sorter. More recently, scientists seeking evidence of a biological basis of personality have further examined the relationship between temperament and character (defined in this context as the learnt aspects of personality). However, biological correlations have proven hard to confirm.[1]


Temperament is determined through specific behavioural profiles, usually focusing on those that are both easily measurable and testable early in childhood. Commonly tested factors include irritability, activity, frequency of smiling, and an approach or avoidant posture to unfamiliar events.[1] There is generally a low correlation between descriptions by teachers and behavioural observations by scientists of features used in determining temperament.[2]

Temperament is hypothesized to be associated with biological factors, but these have proven difficult to test directly.[1]

Temperament factors

Personality factors which may be associated with temperament include:

Infants, children and adults

Alexander Thomas, Stella Chess, Herbert G. Birch, Margaret Hertzig and Sam Korn began the classic New York Longitudinal study in the early 1950s regarding infant temperament (Thomas, Chess & Birch, 1968). The study focused on how temperamental qualities influence adjustment throughout life. Chess, Thomas et al. rated young infants on nine temperament characteristics each of which, by itself, or with connection to another, affects how well a child fits in at school, with their friends, and at home. Behaviors for each one of these traits are on a continuum. If a child leans towards the high or low end of the scale, it could be a cause for concern. The specific behaviors are: activity level, regularity of sleeping and eating patterns, initial reaction, adaptability, intensity of emotion, mood, distractibility, persistence and attention span, and sensory sensitivity. Redundancies between the categories have been found and a reduced list is normally used by psychologists today.[3]

Jerome Kagan and his colleagues have concentrated empirical research on a temperamental category termed "reactivity." Four-month-old infants who became "motorically aroused and distressed" to presentations of novel stimuli were termed highly reactive. Those who remained "motorically relaxed and did not cry or fret to the same set of unfamiliar events" were termed low reactive.[1] These high and low reactive infants were tested again at 14 and 21 months "in a variety of unfamiliar laboratory situations." Highly reactive infants were predominantly characterized by a profile of high fear to unfamiliar events, which Kagan termed inhibited. Contrastingly, low reactive children were minimally fearful to novel situations, and were characterized by an uninhibited profile (Kagan). However, when observed again at age 4.5, only a modest proportion of children maintained their expected profile due to mediating factors such as intervening family experiences. Those who remained highly inhibited or uninhibited after age 4.5 were at higher risk for developing anxiety and conduct disorders, respectively. [1]

Kagan also used two additional classifications, one for infants who were inactive but cried frequently (distressed) and one for those who showed vigorous activity but little crying (aroused). Followed to age 14–17 years, these groups of children showed differing outcomes, including some differences in central nervous system activity. Teenagers who had been classed as high reactives when they were babies were more likely to be "subdued in unfamiliar situations, to report a dour mood and anxiety over the future, [and] to be more religious."[4]

Solomon Diamond described temperaments based upon characteristics found in the animal world: fearfulness, aggressiveness, affiliativeness, and impulsiveness. His work has been carried forward by Buss and Plomin, who developed two measures of temperament: The Colorado Child Temperament Inventory, which includes aspects of Thomas and Chess's schema, and the EAS Survey for Children.[3]

H. Hill Goldsmith and Joseph Campos used emotional characteristics to define temperament, originally analyzing five emotional qualities: motor activity, anger, fearfulness, pleasure/joy, and interest/persistence, but later expanding to include other emotions. They developed several measures of temperament: Lab-TAB and TBAQ.[3]

Other temperament systems include those based upon theories of adult temperament (e.g. Gray and Martin's Temperament Assessment Battery for Children).

Nine Temperament Characteristics of Thomas and Chess

Research by Thomas and Chess used the following nine temperament traits in children[5][6][7][8][9] based on a classification scheme developed by Dr. Herbert Birch:[10]


Activity refers to the child's physical energy. Is the child constantly moving, or does the child have a relaxing approach? A high-energy child may have difficulty sitting still in class, whereas a child with low energy can tolerate a very structured environment. The former may use gross motor skills like running and jumping more frequently. Conversely, a child with a lower activity level may rely more on fine motor skills, such as drawing and putting puzzles together. This trait can also refer to mental activity, such as deep thinking or reading—activities which become more significant as the person matures.


Regularity, also known as Rhythmicity, refers to the level of predictability in a child’s biological functions, such as waking, becoming tired, hunger, and bowel movements. Does the child have a routine in eating and sleeping habits, or are these events more random? For example, a child with a high regularity rating may want to eat at 2 p.m. every day, whereas a child lower on the regularity scale may eat at sporadic times throughout the day.

Initial reaction

Initial reaction is also known as Approach or Withdrawal. This refers to how the child responds (whether positively or negatively) to new people or environments. Does the child approach people or things in the environment without hesitation, or does the child shy away? A bold child tends to approach things quickly, as if without thinking, whereas a cautious child typically prefers to watch for a while before engaging in new experiences.


Adaptability refers to how long it takes the child to adjust to change over time (as opposed to an initial reaction). Does the child adjust to the changes in their environment easily, or is the child resistant? A child who adjusts easily may be quick to settle into a new routine, whereas a resistant child may take a long time to adjust to the situation.


Intensity refers to the energy level of a positive or negative response. Does the child react intensely to a situation, or does the child respond in a calm and quiet manner? A more intense child may jump up and down screaming with excitement, whereas a mild-mannered child may smile or show no emotion.


Mood refers to the child’s general tendency towards a happy or unhappy demeanor. All children have a variety of emotions and reactions, such as cheerful and stormy, happy and unhappy. Yet each child biologically tends to have a generally positive or negative outlook. A baby who frequently smiles and coos could be considered a cheerful baby, whereas a baby who frequently cries or fusses might be considered a stormy baby.


Distractibility refers to the child’s tendency to be sidetracked by other things going on around them. Does the child get easily distracted by what is happening in the environment, or can the child concentrate despite the interruptions? An easily distracted child is engaged by external events and has difficulty returning to the task at hand, whereas a rarely distracted child stays focused and completes the task at hand.

Persistence and attention span

Persistence and attention span refer to the child’s length of time on a task and ability to stay with the task through frustrations—whether the child stays with an activity for a long period of time or loses interest quickly.


Sensitivity refers to how easily a child is disturbed by changes in the environment. This is also called sensory threshold or threshold of responsiveness. Is the child bothered by external stimuli like noises, textures, or lights, or does the child seem to ignore them? A sensitive child may lose focus when a door slams, whereas a child less sensitive to external noises will be able to maintain focus.

"Easy", "difficult", and "slow-to-warm-up"

Thomas, Chess, Birch, Hertzig and Korn found that many babies could be categorized into one of three groups: easy, difficult, and slow-to-warm-up (Thomas & Chess 1977).[5] Not all children can be placed in one of these groups. Approximately 65% of children fit one of the patterns. Of the 65%, 40% fit the easy pattern, 10% fell into the difficult pattern, and 15% were slow to warm up. Each category has its own strength and weakness and one is not superior to another.

Thomas, Chess, Birch, Hertzig and Korn showed that Easy babies readily adapt to new experiences, generally display positive moods and emotions and also have normal eating and sleeping patterns. Difficult babies tend to be very emotional, irritable and fussy, and cry a lot. They also tend to have irregular eating and sleeping patterns. Slow-to-warm-up babies have a low activity level, and tend to withdraw from new situations and people. They are slow to adapt to new experiences, but accept them after repeated exposure.

Thomas, Chess, Birch, Hertzig and Korn found that these broad patterns of temperamental qualities are remarkably stable through childhood. These traits are also found in children across all cultures.

Thomas and Chess also studied temperament and environment. One sample consisted of white middle class families with high educational status and the other was of Puerto Rican working class families. They found several differences. Among those were:[5]

  • Parents of middle class children were more likely to report behavior problems before the age of nine and the children had sleep problems. This may be because children start preschool between the ages of three and four. Puerto Rican children under the age of five showed rare signs of sleep problems, however, sleep problems became more common at the age of six.
  • Middle class parents also placed great stress on the child’s early development, believing that problems in early ages were indicative of later problems in psychological development, whereas Puerto Rican parents felt their children would outgrow any problems.
  • At the age of nine, the report of new problems dropped for middle class children but they rose in Puerto Rican children, possibly due to the demands of school.

Family life


Most experts agree that temperament does have a genetic and biological basis, although environmental factors and maturation modify the ways a child's personality is expressed.[11] Differences of temperament or behavior styles among each individual are important in family life. They affect the interactions among family members. While some children can adapt quickly and easily to family routines and get along with siblings, others who are more active or intense may have a difficult time adjusting. The interactions between these children and their parents and/or siblings are among a number of factors that can lead to stress and friction within the family life.

Parents can also differ in temperament. The mix between parents and children also has an effect on family life. The term “Goodness of fit” refers to the match or mismatch between children and other family members. For example, a slow paced parent may be irritated by a highly active child or if both parent and child are highly active and intense it could mean big conflict. This can be useful to parents for figuring out how temperaments affect family relationships. What may appear to be a behavioral problem may actually be a mismatch between the parent’s temperament and their child’s. By taking a closer look at the nine traits that Thomas and Chess revealed from their study, parents can gain a better understanding of their child’s temperament and their own. Parents may also notice that situational factors cause a child's temperament to seem problematic; for example, a child with low rhythmicity can cause difficulties for a family with a highly scheduled life, and a child with a high activity level may be difficult to cope with if the family lives in a crowded apartment upstairs from sensitive neighbors.

Parents can encourage new behaviors in their children, and with enough support a slow-to-warm-up child can become less shy, or a difficult baby can become easier to handle. More recently infants and children with temperament issues have been called "spirited" to avoid negative connotations of "difficult" and "slow to warm up". Numerous books have been written advising parents how to raise their spirited youngsters.

Understanding for improvement

Understanding a child’s temperament can help reframe how parents interpret children’s behavior and the way parents think about the reasons for behaviors. By parents having access to this knowledge now helps them to guide their child in ways that respect the child’s individual differences. By understanding children’s temperaments and our own helps adults to work with them rather than try to change them. It is an opportunity to anticipate and understand a child’s reaction. It is also important to know that temperament does not excuse a child’s unacceptable behavior, but it does provide direction to how parents can respond to it. Making small and reasonable accommodations to routines can reduce tension. For example a child who is slow paced in the mornings may need an extra half hour to get ready. Knowing who or what may affect the child’s behavior can help to alleviate potential problems. Although children obtain their temperament behaviors innately, a large part that helps determine a child's ability to develop and act in certain ways is determined by the parents. When a parent takes the time to identify and more importantly respond to the temperaments they are faced with in a positive way it will help them guide their child in trying to figure out the world.

Recognizing the child’s temperament and helping them to understand how it impacts his/her life as well as others is important. It is just as important for parents to recognize their own temperaments. Recognizing each individual’s temperament, will help to prevent and manage problems that may arise from the differences among family members.

Temperament continues into adulthood, and later studies by Chess and Thomas have shown that these characteristics continue to influence behavior and adjustment throughout the life-span.

In addition to the initial clinical studies, academic psychologists have developed an interest in the field and researchers such as Bates, Buss & Plomin, Kagan, and Rothbart have generated large bodies of research in the areas of personality, neuroscience, and behavioral genetics.

In the second century A.D. the physician Galen described four temperaments - melancholic, phlegmatic, sanguine and choleric - based upon the four humours or bodily fluids. These became known as the four classical temperaments.

Rudolf Steiner's four temperaments

Rudolf Steiner emphasized the importance of the four classical temperaments in elementary education, the time when he believed the influence of temperament on the personality to be at its strongest.[12][13] He hypothesized that temperament diminishes in importance as the personality becomes more developed after puberty; that a person's temperament may change, especially in the pre-puberty years; and that temperament is not exclusive: people may combine aspects of several or even, in unusual cases, all of them. He also suggested that people are capable of transforming their own temperaments.

For each temperament Steiner described less and more mature forms: the introspective and sensitive melancholic may be sullen and self-absorbed but can also become a sympathetic helper or a deep thinker. Steiner's temperaments are often used as a basis to describe and understand children during the elementary-school years in Waldorf schools.
