1.
IQ seems to be distributed throughout the population according to a phenomenon called the bell-shaped curve.
Correct Answer
A. True
Explanation
The statement is true because IQ scores are indeed distributed throughout the population according to a bell-shaped curve, also known as a normal distribution. This means that most people fall within the average range of IQ scores, with fewer individuals falling in the lower and higher ranges. The bell-shaped curve reflects the statistical distribution of IQ scores, with the majority of people having average intelligence and fewer people having below or above average intelligence.
2.
An IQ test measures only how a child performs at one point in time on the items included on the test
Correct Answer
A. True
Explanation
This statement is true because an IQ test is designed to assess a child's intelligence and cognitive abilities at a specific moment in time. It does not provide a comprehensive or permanent measure of a child's overall intelligence or potential. IQ scores can fluctuate over time due to various factors such as age, experience, and learning opportunities. Therefore, it is important to interpret IQ test results cautiously and consider them as a snapshot of a child's abilities rather than a definitive measure of their intelligence.
3.
Memory is the collection of conceptual, social, and pratical skills that have been learned by people in order to function in their everyday lives.
Correct Answer
B. False
Explanation
The statement suggests that memory is a collection of conceptual, social, and practical skills that people have learned to function in their everyday lives. However, this is not an accurate definition of memory. Memory refers to the ability to store, retain, and recall information or experiences. It is not limited to skills, but rather encompasses the retention and recollection of various types of information. Therefore, the correct answer is False.
4.
Researchers have identified more than 350 causes of mental reatardation
Correct Answer
A. True
Explanation
The statement is true because researchers have indeed identified more than 350 causes of mental retardation. This indicates that there are numerous factors, such as genetic abnormalities, prenatal exposure to toxins, and certain medical conditions, that can contribute to the development of mental retardation. The extensive research in this field has allowed for a better understanding of the causes and potential interventions for individuals with mental retardation.
5.
A prenatal test that may eventually replace amniocentesis is genetic villi sampling
Correct Answer
B. False
Explanation
Genetic villi sampling (CVS) is a prenatal test that involves taking a small sample of cells from the placenta to test for genetic abnormalities. While CVS is a common alternative to amniocentesis, it cannot completely replace it. Amniocentesis involves extracting a small amount of amniotic fluid for genetic testing and is still considered the gold standard for certain conditions. Therefore, the statement that CVS may eventually replace amniocentesis is false.
6.
Is the rate at which children with intellectual disabilities acquire new knowledge and skills
Correct Answer
learning rate
Explanation
The learning rate refers to the speed at which children with intellectual disabilities are able to acquire new knowledge and skills. It measures how quickly they are able to learn and progress in their learning journey.
7.
Down syndrome and fragile X syndrome are the two most common genetic causes of mental retardation
Correct Answer
A. True
Explanation
Down syndrome and fragile X syndrome are indeed the two most common genetic causes of mental retardation. Down syndrome is caused by the presence of an extra copy of chromosome 21, while fragile X syndrome is caused by a mutation in the FMR1 gene. Both conditions can lead to intellectual disabilities and developmental delays.
8.
Emotional disturbance is not one of the disability categories in the IDEA which a child is eligible to receive special education services
Correct Answer
B. False
Explanation
The statement is false because emotional disturbance is actually one of the disability categories recognized by the IDEA (Individuals with Disabilities Education Act) under which a child is eligible to receive special education services. The IDEA includes emotional disturbance as a specific category that encompasses conditions such as anxiety, depression, and bipolar disorder, among others. Therefore, children with emotional disturbance can receive special education services to address their specific needs and support their academic and emotional development.
9.
Too little social interaction with others is known as
Correct Answer
B. Internalizing behaviors
Explanation
Internalizing behaviors refer to the tendency of individuals to internalize their emotions and experiences, resulting in withdrawal, isolation, and limited social interaction with others. This can manifest as social anxiety, depression, or other mental health issues. Bulimia is a type of eating disorder characterized by binge eating and purging, while anxiety is a general term for excessive worry and fear. Therefore, the correct answer is internalizing behaviors as it specifically relates to the lack of social interaction.
10.
Maladaptive emotional state or behaviors caused by excessive and often irrational fears and worries is anxiety disorder
Correct Answer
A. True
Explanation
The given statement is true. Anxiety disorder refers to maladaptive emotional states or behaviors that are caused by excessive and often irrational fears and worries. This disorder can significantly impact a person's daily life and functioning.
11.
Many more children with emotional or behavioral disorders score in the high learner or mild intellectual disabilities range on IQ tests than do children without disabilities
Correct Answer
B. False
Explanation
The statement is false because children with emotional or behavioral disorders are more likely to score lower on IQ tests, rather than in the high learner or mild intellectual disabilities range.
12.
No agreed-upon definition of temperament exists.
Correct Answer
A. True
Explanation
The statement suggests that there is no universally accepted definition of temperament. This implies that different individuals or groups may have different interpretations or understandings of what temperament means. Therefore, the statement is true because there is no consensus on a single definition of temperament.
