, -Convention, IQ scores(with mean of 100 & standard
deviation of 15) Derived from standardized table
on a person’s age & test score
- Intelligence defined:
1. normal distribution: approx. 95% of population has scores within 2 st
deviations of the mean e.g. between 70 and 130
2. Understand & identify subaverage intellectu
2. Subaverage intelligence: IQ of about 70 or below(approx. 2 stan
deviations below the mean)
-Definition of “Intellectual disability”—> not only subaverage level of ada
functioning but ALSO subaverage level of adaptive functioning
-Adaptive functioning: how effectively individuals cope with ordinary
& how capable they are of living independently and abiding by comm
standards.
NOTE- some children + adolescents may learn to adapt quite well to
environment despite their lower intelligence as measured by IQ tests
not be considered to have an intellectual disability
3 major categories of adaptive behavior:
1. Conceptual skills(receptive & expressive language, reading & writing,
concepts, self-directions)
2. Social skills(interpersonal, responsibility, self-esteem, gullibility, naïvet
rules, obeys laws, avoids victimization)
