Observational Learning Learning through watching appears to be a good approach, given the tendency towards outer- directedness Suggestions: –be aware that any behavior (even unwanted ones) may serve as a model –use prompts or cues to direct students’ attention –call attention to students exhibiting desirable behavior –ignore undesirable behavior so that others do not model it in an attempt to gain attention, –reward imitation of appropriate behavior.

29. (c) 2006 by Pearson Education. All Rights Reserved. General Not every person who has mental retardation may display all the characteristics discussed in this chapter. The “mild” label refers to individuals who require few or no supports systems in most adaptive skills areas. People with mild intellectual disabilities are a heterogeneous group. These individuals have been referred to as educable or trainable in the past. Beirne-Smith et al. Mental Retardation, Seventh Edition Copyright ©2006 Pearson Education, Inc. Upper Saddle River, New Jersey 07458 All rights reserved.

30. (c) 2006 by Pearson Education. All Rights Reserved. Demographics More males than females are identified. Historically there have been a disproportionate number of racially different and ethnic minority children labeled with mild mental retardation. Recent data support the description that many youth with intellectual disabilities live in blended families and come from families characterized by lower socioeconomic status. Beirne-Smith et al. Mental Retardation, Seventh Edition Copyright ©2006 Pearson Education, Inc. Upper Saddle River, New Jersey 07458 All rights reserved.

31. (c) 2006 by Pearson Education. All Rights Reserved. Learning and Motivation Motivational characteristics include external locus of control, expectancy for failure, outer-directedness, and more limited self-regulatory behaviors. Social and behavioral problems are more likely, with some students displaying psychiatric problems as well. There is some difference of opinion whether cognitive development is qualitatively or quantitatively different from the general population. Various processes (attention, mediation strategies, memory, generalization) associated with learning can be problematic for this group. Beirne-Smith et al.

32. (c) 2006 by Pearson Education. All Rights Reserved. Speech, Language, & Health Speech and language problems occur with great frequency among individuals with intellectual disabilities. Delayed language development frequently is a characteristic Motor development may be delayed in children who are retarded. Sensory deficits are more common among persons who have intellectual disabilities. Individuals with Down syndrome have a number of physical health considerations. Cerebral palsy and seizure disorders occur more frequently in persons who have intellectual disabilities. The data on the extent of substance abuse in this group are equivocal at this time.

33. (c) 2006 by Pearson Education. All Rights Reserved. Educational Characteristics Students with mental retardation are being served more frequently in general education classrooms for greater portions of the school day. Studies of IEP goals indicate a predominance of academic goals. Many students who have intellectual disabilities qualify for related services. The school exit rate for students with mental retardation has remained fairly stable over the past 5 years. Beirne-Smith et al.
