[5] After that project was completed, he accepted the offer he received from Harvard University to be involved in creating the first Human Development program. These are questions that psychologist Jerome Kagan is interested in. Longitudinal studies conducted for several purposes in different cohorts of children aged from 2 months (Kagan & Snidman, 1991) to over 7 years (e.g., Kagan et al., 1988; Reznick et al., 1986) showed that the majority of inhibited and uninhibited infants selected from Caucasian samples did not change their temperament characteristics even in late childhood. For school-age children classroom behavior recorded during different experimental settings was also taken as a temperament measure. This is a personality trait known as inhibited,” said Kagan. Jerome Kagan (born February 25, 1929) is an American psychologist, and Daniel and Amy Starch Research Professor of Psychology, Emeritus at Harvard University, and co-faculty at the New England Complex Systems Institute. 139-143 Published by: Blackwell Publishing on behalf of the Society for Research in Child Only a few studies have been conducted by Kagan and his associates in which the inhibited-uninhibited temperaments were related to behaviors that were not considered to be expressions ofthe two temperament types. Before his involvement in studies on temperament, Kagan (1974) had already put forward a temperament hypothesis for the interpretation of changes in infants' behavior following presentations of discrepant objects.

Nearly two thousand years ago a physician named Galen of Pergamon suggested that much of the variation in human behavior could be explained by an individual's temperament. The Long Shadow of Temperament. Rats behave as if they have the capacity for being fearful, surprised, or sexually aroused. These biases, which appear early in development, are sculpted by experience into a variety of personality profiles. Professor Kagan's research, on the cognitive and emotional development of a child during the first decade of life, focuses on the origins of temperament. The two temperaments are relatively stable. They found that about 20% of healthy four-monthold infants reacted to stimulation with thrashing and distress. Yet when parents of shy infants encourage boldness and sociability, the children become adolescents who exhibit less inhibition than their more fearful counterparts. Since the correlations between the physiological measures were rather low, varying between-. Infants with an inhibited temperament tend to develop into children who avoid people, objects, and situations that are novel or unfamiliar, whereas uninhibited children spontaneously approach novel persons, objects, and situations. Jerome Kagan Harvard University ABSTRACT: About 15% of Caucasian children in the second year of life are consistently shy and emotionally subdued in unfamiliar situations, whereas another 15% are consistently sociable and affectively spontaneous. Throughout his 44 years of research on child development, Harvard University psychologist Jerome Kagan, PhD, has found that temperamental differences in adults and children are due to both environmental and genetic influences. The constructs inhibited and uninhibited to the unfamiliar refer to children who fall at the extremes of a phenotypic continuum from shyness and restraint to sociability and affective spontaneity. He began his work on temperament after his research in Guatemala. A majority of the children in these two groups retain these profiles through their eighth year. Introduction. Identifying two extreme temperamental types—inhibited and uninhibited in childhood, and high-reactive and low-reactive in very young babies—Kagan and his colleagues returned to these children as adolescents. Since different situations provide a different set of incentives for the manifestation of inhibited-uninhibited behavior, an aggregate index of inhibition was often used by Kagan and his coworkers. Separation from the mother, reactions to unfamiliar objects, such as unusual toys, robots, and sounds, and to an unknown person or group of persons (children, adults) were considered the most critical situations provoking behavior typical for the inhibited and uninhibited temperament. Children with an inhibited temperament are cautious, restrained and even fearful in response to unfamiliar people, objects and situations. Data from this study show that inhibited temperament as measured by means of behavioral observations had a heritability score of .62, one of the highest scores among the temperament characteristics under study. [7] While at Yale University, he assisted Frank Beach, a well respected researcher. In The Long Shadow of Temperament, Kagan and Nancy Snidman summarize the results of this unique inquiry into human temperaments, one of the best-known longitudinal studies in developmental psychology.

Second, a study conducted about 15 years later by Kagan, Kearsley, and Zelazo (1978) on 3- to 29-month-old children showed that Chinese children differ essentially from Caucasian children in some behavior characteristics that could not be explained in terms of rearing practices. They sought to determine whether, how, and to what extent high- and low-reactive infants retained their basic profiles of inhibition and uninhibitedness over time. Schwartz C, Snidman N, Kagan J (1999). Journal of the American Academy of … He has tracked the development of inhibited and uninhibited children from infancy to adolescence. A child who is consistently shy, quiet, cautious, emotionally reserved, and timid, when confronted with unfamiliar events, is characterized as having an inhibited temperament.
