A child with mental retardation but not autism is more likely to display_______ than a child with autism.

A.self injurious behavior
b.Smiling and eye contact
c.sterotyped motor behaviors
d.self-stimulatory behaviors

i chose c but could you help or any websites that might be helpful

I disagree.

Do autistic children smile and make eye contact with others?

i don't think so ?

Check the symptoms of autism here.

thank you so much

You're very welcome.

If motivation consists only of drive-reduction, what is the perfect state of a human being?

To determine the most likely answer to this question, it would be best to understand the characteristics and behaviors associated with mental retardation and autism.

Mental retardation, also known as intellectual disability, is typically marked by significant limitations in cognitive functioning and adaptive behaviors. These limitations can affect a person's ability to learn, communicate, and perform daily tasks.

Autism, on the other hand, is a developmental disorder characterized by difficulties in social interaction, communication, and restricted or repetitive patterns of behavior.

Given this information, let's analyze the options:

a. Self-injurious behavior: While self-injurious behavior can occur in both individuals with mental retardation and autism, it is not exclusive to either condition. Both groups can exhibit self-injurious behaviors, such as headbanging, hitting themselves, or biting. Therefore, this option cannot be determined as the most likely answer.

b. Smiling and eye contact: Smiling and eye contact are more commonly associated with typically developing individuals or individuals with mental retardation rather than autism. Many individuals with autism may have difficulties establishing and maintaining eye contact, as well as expressing social smiles. However, it is important to note that some individuals with autism can develop these skills with intervention. Therefore, this option is less likely to be the correct answer.

c. Stereotypical motor behaviors: Stereotypical motor behaviors, also referred to as stereotypies, are repetitive and seemingly purposeless movements. These can include hand flapping, rocking, or finger flicking. While these behaviors can be present in both individuals with mental retardation and autism, they are more strongly associated with autism. Research suggests that individuals with autism are more likely to exhibit stereotypies compared to individuals with mental retardation. Therefore, this option could be the correct answer.

d. Self-stimulatory behaviors: Self-stimulatory behaviors, also known as stimming, are repetitive and self-soothing behaviors. These can include hand flapping, body rocking, spinning, or finger twiddling. Similar to stereotypies, self-stimulatory behaviors are more strongly associated with autism. Individuals with mental retardation can also engage in self-stimulatory behaviors, but they are more commonly observed in individuals with autism. Therefore, this option could also be a correct answer.

While c and d are both plausible answers, based on the literature, stereotypies (option c) are more closely associated with autism than self-stimulatory behaviors (option d). Thus, "c. stereotyped motor behaviors" is the more likely answer.
