Dr. Karen Rogers, a researcher of international renown, analyzed data at the Gifted Development Center in 1994-1995 during a postdoctoral fellowship.   The analysis consisted of data on 241 children between 2½ and 12½ years of age, with IQs ranging from 160 to 237+ on the Stanford-Binet Intelligence Scale (Form L-M). Here are some of the findings from that study:

Reasons for Assessment

The main reason parents requested testing (82%) was to obtain help with educational placement decisions.

Gender Differences

There was no difference in the mean IQ for boys and girls.

Birthing Issues

Mothers tended to be older than the norm. The mean age at the time of the child’s birth was 30.8.

44% of the mothers report problems with delivery.

Sleep Patterns

50% of the parents report that their child needed less sleep than others.

60% are "day people" (more boys than girls), 17.5% are night people (more girls than boys) and 22.5% of the parents wrote in "both" in answer to the question!

Development in Infancy and Toddlerhood

94% were very alert as infants.

94% had a long attention span as an infant or toddler.

91% showed early language development.

60% showed early motor skill development.

48.9% were ambidextrous at some period of their development.

37% had imaginary playmates.

Language Development

The mean age at which these children spoke their first word was 9 months.

The mean age at which the children sight read an easy reader was before four.

Medical Issues

85% of the children had had ear infections.

52% have high pain tolerance.

44% have allergies and 9.6% have asthma.

The most significant allergy mentioned was to milk (35% of the allergic children).

The next highest allergy mentioned was trees (8.2%).

Most Prevalent Characteristics of Giftedness

99.4% learn rapidly

99.4% have extensive vocabulary

99.3% have excellent memory

99.3% reason well

97.9% are curious

96.1% are mature for their age at times

95.9% have an excellent sense of humor

93.8% have a keen sense of observation

93.5% have compassion for others

93.4% have a vivid imagination

93.4% have a long attention span

92.9% have ability with numbers

90.3% are concerned with justice and fairness

89.4% have facility with puzzles and legos

88.4% have a high energy level

88.3% are perfectionistic

85.9% are perseverant in their areas of interest

84.1% question authority

80.3% are avid readers


90% were described by their parents as "sensitive."

83% like to concentrate on one activity at a time.

79% report high energy or activity levels.

44% are sensitive to clothing tags and other tactile sensations.


In tests of self-concept, these children are significantly more confident in their academic abilities than in their social acceptance.

Educational Needs

The greatest educational need expressed was for a more challenging curriculum.

How significant are these data? We won't know until we've been able to enter random samples from the moderate, mildly and non-gifted children's files.
