Temperament
What is Temperament?
- Temperament: individuals have a general emotional style that guides their tendency to respond in certain ways to a variety of events in their environment.
- Individual way of approaching the world, in turn shapes behavior and development
Thomas and Chess
- NY Longitudinal Study , Thomas & Chess studied 133 infants into adulthood
- Asked parents about activity level, excitability, response to novel situations and people, food, bowel, and sleep patterns, mood, sensitivity
- Easy child (40%): a positive mood, quickly establishes routines, and easily adapts.
- Difficult child (10%): irritable, reacts negatively and cries frequently, resists change, and shows irregular behaviors.
- Slow-to-warm-up child (15%): low mood intensity, low activity level, and slow to adapt to new people and situations
- = 65, so 35% did not fit into one of these categories
Is Temperament Stable Over Time?
- Thought to be more “hard-wired”. There is some stability in temperament over time
- Change can also be and is observed; Temperamental characteristics do not, however, typically go from one extreme to another.
- One reason why we see change is that the ethnicity and culture the child is growing up may value and encourage certain child characteristics over others.
Biology and Environment - Development of Shyness and Sociability
- Neurobiological research has focused on inhibited, or shy, children and uninhibited, or sociable, children (introversion and extroversion).
- Neurobiological and physiological correlates of shyness:
- Individual differences in arousal of the amygdala (fear response), and in brain waves in the frontal lobes of cerebral cortex
- Heart rate higher in shy children, speeds up further during unfamiliar events
- Higher cortisol concentration in saliva, rises more when stressed
- Greater pupil dilation, rise in blood pressure, and lower skin surface temperature when faced with novelty
Genetic and Environmental Influences
- Stability of temperament is low to moderate in infancy and toddlerhood and moderate from the preschool years on.
- Long-term prediction from early temperament is best achieved after age 3.
- Heritability estimates suggest a moderate role for genetic factors in temperament and personality, but environment is also powerful.
- A child’s initial approach to the world can be intensified or lessened by experience. Thus children can and do adapt
- Differences in early temperament may have genetic roots but also supported by cultural beliefs and practices.
Parenting
- Goodness-of-fit model explains how temperament and environment can together produce favorable outcomes
- The fit between parent and child temperament is also moderated by cultural value, parental mental health, marital happiness, and favorable economic conditions.
- Parents, caregivers and educators play a big role in recognizing and supporting a child’s natural temperament, while recognizing their individual differences
- E.g. an intense, reactive child may need more time to calm down and soothe; a slow to warm child may need more preparedness for new situations and time to adjust to transitions or new routines
- **The goal is not to CHANGE the child, but rather nurture their strengths, help them feel supported, accepted, and confident when faced with new or unfamiliar situations or challenging tasks
- Parents should recognize their own temperament and styles, may be difficult to parent a child who has a temperament different than one’s own. Be aware of their own limitations, influences
