Correct Answer: C

Rationale: The correct answer is C: Reactive attachment disorder. Individuals with reactive attachment disorder have a history of severe social neglect, which distinguishes it from autism spectrum disorder. Choice A, Schizoid personality disorder, is incorrect as it is not typically associated with the history described in reactive attachment disorder. Choice B, Autism spectrum disorder, is incorrect because individuals with autism spectrum disorder do not necessarily have a history of severe social neglect. Choice D, Disinhibited social engagement disorder, is also incorrect as it is a separate attachment disorder characterized by indiscriminate social behavior, not necessarily a history of neglect.

Correct Answer: D

Rationale: The correct order of the three stages of prenatal development is germinal stage, embryonic stage, and fetal stage. During the germinal stage, the fertilized egg rapidly divides and implants in the uterine wall. The embryonic stage follows, where major organs and systems begin to develop. Finally, during the fetal stage, the developing organism is known as a fetus and continues to grow and mature. Choice A is incorrect because it has the stages in the wrong order. Choice B is incorrect as it also presents the stages out of order. Choice C is incorrect as it reverses the order of the stages. Therefore, the correct answer is D.

Correct Answer: A

Rationale: Colleen's behavior of seeking attention and manipulating others by threatening self-harm to elicit a response from her psychology instructor aligns with the characteristics of borderline personality disorder. This disorder is characterized by unstable relationships, impulsive actions, and efforts to avoid real or imagined abandonment. Choices B, C, and D are incorrect because they do not match Colleen's behavior as described in the scenario. Schizoid personality disorder is characterized by a lack of interest in social relationships, Schizotypal personality disorder involves social anxiety and odd behavior, and Antisocial personality disorder is characterized by a disregard for others' feelings and violating their rights.

Correct Answer: B

Rationale: The correct answer is 'Lifespan perspective.' This perspective highlights that significant developmental changes occur throughout a person's entire life, emphasizing continuous growth and development. Choice A, 'Multicultural perspective,' refers to the consideration of cultural influences on development rather than the timeline of changes. Choice C, 'Atypical development,' pertains to deviations from typical developmental patterns and is not directly related to the continuous changes across the lifespan. Choice D, 'Maturation,' specifically refers to the biological process of growth and development, which is different from the broader concept of developmental changes occurring across the lifespan.

Correct Answer: D

Rationale: The correct answer is D, 'Long-term memory.' In the 5th substage of sensorimotor development, Piaget refers to 'experimentation' as tertiary circular reactions, where the infant tries out new ways of playing with or manipulating objects. This stage involves exploring and testing different ways of interacting with the world to understand cause and effect relationships. Choices A, B, and C are incorrect as they do not align with Piaget's concept of tertiary circular reactions and experimentation in the sensorimotor stage of development.
