Arrange the three stages of prenatal development in the correct order.
- A. Germinal stage, fetal stage, embryonic stage
- B. Fetal stage, embryonic stage, germinal stage
- C. Embryonic stage, germinal stage, fetal stage
- D. Germinal stage, embryonic stage, fetal stage
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.

Classical and operant conditioning theories are classified under _________________, while sociocultural theory and Piaget's theory fall under ________________.?
- A. Psychodynamic; cognitive
- B. Learning; behavior modelling
- C. Behavioral; sociocultural
- D. Centration; cognitive
Correct Answer: A
Rationale: Classical and operant conditioning theories are forms of learning theories, making them fall under the category of cognitive theories. On the other hand, sociocultural theory and Piaget's theory are cognitive theories that focus on how individuals perceive and process information, hence correctly classified under cognitive theories. Therefore, choice A is the correct answer. Choices B, C, and D are incorrect as they do not accurately represent the classifications of the specified theories.
To overcome her fear of balloons due to the loud sound they might make when popping, Bella must sit in a room filled with balloons while the therapist pops each one. After a while, Bella realizes that her fear is unjustified and even begins to pop balloons herself. This technique is known as?
- A. Systematic desensitization
- B. Aversion therapy
- C. Flooding
- D. Extinction
Correct Answer: C
Rationale: The correct answer is C, Flooding. Flooding is an exposure therapy technique where a person is exposed to their fear at full intensity until the fear subsides. In this scenario, Bella is exposed to her fear of balloons in a controlled environment until she realizes her fear is unjustified. Choice A, Systematic desensitization, involves gradual exposure to the fear stimulus paired with relaxation techniques. Choice B, Aversion therapy, aims to create a negative association with a stimulus to reduce unwanted behavior. Choice D, Extinction, refers to the gradual decrease in the strength or frequency of a conditioned response.
What does incidence refer to?
- A. How many new cases of a disorder occur during a given period of time
- B. How many people have recovered from a disorder in a given period of time
- C. The percentage of males and females who have a disorder
- D. How many people in the population as a whole have a disorder
Correct Answer: A
Rationale: The correct answer is A: 'How many new cases of a disorder occur during a given period of time.' Incidence specifically measures the rate of occurrence of new cases of a particular condition within a defined population and time frame. This distinguishes it from prevalence, which includes both new and existing cases. Choices B, C, and D are incorrect because they do not accurately define the term 'incidence.' Choice B refers to recovery, choice C mentions gender distribution, and choice D relates to the total population affected by a disorder, which are not reflective of the concept of incidence.
In a breech presentation, how is the infant positioned for delivery?
- A. Is too large to be delivered vaginally.
- B. Is delivered feet or bottom first.
- C. Is delivered head first.
- D. Appears face down.
Correct Answer: B
Rationale: In a breech presentation, the infant is positioned to be delivered feet or bottom first. This is because the baby's pelvis or feet enter the birth canal before the head. Therefore, choice B is correct. Choices A, C, and D are incorrect because a breech presentation specifically refers to the baby being positioned feet or bottom first, not head first, face down, or being too large for vaginal delivery.
The ____ believed that consciousness developed in humans because it serves a useful purpose?
- A. Behaviorists
- B. Humanists
- C. Functionalists

Rationale: Functionalists believed that consciousness evolved because it serves a useful purpose in helping humans adapt to their environment. Choice A, Behaviorists, focused on observable behaviors rather than consciousness. Choice B, Humanists, emphasized human potential and self-actualization. Choice D, Structuralists, studied the basic elements of consciousness rather than its function and purpose.
