Kai and Ken received their Christmas gifts from their parents. Although their gifts vary in many characteristics, the two compared their gifts based on size. This tendency among children is known as:

Correct Answer: D

Rationale: The correct answer is D, Overextension. Overextension happens when children compare objects or experiences based on one characteristic, such as size. Choices A, B, and C are incorrect. Semiotic refers to the study of signs and symbols; Abstraction is the process of thinking about something as a general concept rather than a specific example; Preoperational is a stage in Piaget's theory of cognitive development, not related to comparing gifts based on size.

Correct Answer: D

Rationale: It is discouraged to use terms like 'schizophrenic', 'autistic', and 'retarded' when referring to people with mental illness because people with mental illness should not be defined solely by their condition. Using such labels can reduce individuals to just their diagnosis, overlooking their individuality and other aspects of their identity. It is essential to treat individuals with mental illness with respect and dignity, focusing on their humanity rather than reducing them to a label. Choices A, B, and C are incorrect because the main reason for discouraging these terms lies in not defining individuals by their conditions, rather than the terms being in or out of the DSM, the number of diagnosed individuals, or the perception of whether there is anything wrong with using such terms.

Correct Answer: A

Rationale: An acute onset refers to the sudden development of symptoms, whereas an insidious onset indicates a gradual progression of symptoms. Therefore, the correct answer is 'Suddenly;gradually.' The other choices are incorrect because 'atypically' does not accurately describe the onset of symptoms in this context.

Correct Answer: A

Rationale: The correct answer is A. Children with conduct disorder often exhibit behaviors such as arguing with adults, ignoring rules, deliberately annoying others, and displaying anger and resentment. Choice B describes symptoms more characteristic of ADHD (Attention-Deficit/Hyperactivity Disorder). Choice C describes symptoms commonly seen in individuals with autism spectrum disorders. Choice D outlines behaviors associated with oppositional defiant disorder rather than conduct disorder.

Correct Answer: D

Rationale: Disinhibited social engagement disorder is the correct answer because it is characterized by a pattern of behavior involving culturally inappropriate and overly familiar behavior with relative strangers. This disorder is marked by a lack of social boundaries and caution when interacting with unfamiliar individuals. Schizoid personality disorder (Choice A) is characterized by a lack of interest in social relationships, Autism spectrum disorder (Choice B) involves challenges with social interactions and communication, and Reactive attachment disorder (Choice C) is typically associated with difficulty forming emotional bonds with caregivers, not with overly familiar behavior with strangers.
