What is the term for a fluid-filled sac in which the baby floats until just before it is born?
- A. Amnion
- B. Placenta
- C. Umbilical cord
- D. Embryo
Correct Answer: A
Rationale: The correct answer is A: Amnion. The amnion is a fluid-filled sac that surrounds and protects the developing fetus in the womb. It acts as a cushion, maintaining a stable temperature and protecting the fetus from external pressure. Choices B, C, and D are incorrect because the placenta is an organ that provides nutrients and oxygen to the fetus and removes waste products, the umbilical cord connects the fetus to the placenta to facilitate nutrient exchange, and an embryo is an early stage of development before it becomes a fetus.

Deferred imitation of a caregiver's behavior shows that toddlers have the capacity to form?
- A. Short-term memory
- B. Working memory
- C. Core memories
- D. Long-term memory
Correct Answer: D
Rationale: Deferred imitation refers to the ability of toddlers to observe and replicate behaviors after a period of time, indicating the formation of long-term memories. This process involves storing information for an extended period and recalling it at a later time. This capacity is not attributed to short-term memory (choice A), which is more temporary in nature and has limited storage capacity. Working memory (choice B) involves the temporary storage and manipulation of information for cognitive tasks, not necessarily the long-term retention of behaviors. Core memories (choice C) are typically associated with emotional or significant events rather than the replication of observed behaviors. Therefore, the correct answer is choice D, as deferred imitation demonstrates toddlers' capability to form long-term memories by replicating behaviors observed earlier.
Which disorder is characterized by a pattern of behavior that involves culturally inappropriate, overly familiar behavior with relative strangers?
- A. Schizoid personality disorder
- B. Autism spectrum disorder
- C. Reactive attachment disorder
- D. Disinhibited social engagement 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.
Sandy took part in the April 2013 Boston Marathon, where two bombs were detonated near the finish line, killing three spectators. For approximately 2 weeks after the marathon, Sandy was unable to sleep or concentrate and often found herself reliving the moment she heard the bombs explode. What disorder might Sandy be diagnosed with?
- A. Posttraumatic stress disorder
- B. Phobic disorder
- C. Panic disorder
- D. Acute stress disorder
Correct Answer: A
Rationale: Sandy might be diagnosed with posttraumatic stress disorder (PTSD). PTSD typically develops after exposure to a traumatic event and is characterized by symptoms such as re-experiencing the event, avoidance of reminders of the event, negative changes in thoughts and mood, and heightened reactivity. While acute stress disorder can occur shortly after a traumatic event, the duration of symptoms in the scenario suggests a more prolonged impact, aligning with PTSD. Phobic disorder and panic disorder are not as closely related to the described symptoms as PTSD.
A psychological disorder is said to have an acute onset if the symptoms develop ______, while it has an insidious onset if the symptoms develop ______.
- A. Suddenly;gradually
- B. Suddenly;atypically
- C. Gradually;atypically
- D. Atypically;suddenly
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.
William James, who was a pioneer in the development of functionalism, was most heavily influenced by?
- A. Charles Darwin.
- B. Sigmund Freud.
- C. John Watson.
- D. B.F. Skinner.
Correct Answer: A
Rationale: William James was heavily influenced by Charles Darwin's theory of evolution, which shaped his functionalist views on psychology. This influence is evident in James's emphasis on adaptation, survival, and the functional purposes of behavior. Choice B, Sigmund Freud, is incorrect because Freud's psychoanalytic theory focused on unconscious processes and childhood experiences, which differ significantly from James's functionalism. Choice C, John Watson, is incorrect as Watson was a behaviorist who emphasized observable behavior and rejected mental processes, which contrasts with James's focus on mental processes. Choice D, B.F. Skinner, is also incorrect as Skinner was a behaviorist known for his work on operant conditioning, which is not directly aligned with James's functionalist perspective.
