1. In an experiment, the investigators manipulate variables to learn how one affects another.?

• A. A data-collection method in which participants respond to questions
• B. The entire group that is of interest to a researcher
• C. A detailed description of a single culture or context
• D. A study that tests a causal hypothesis

Correct answer: D

Rationale: The correct answer is D because in an experimental design, investigators manipulate variables to determine the effect of one on another. This process allows researchers to test causal hypotheses by manipulating one variable while keeping others constant. Choices A, B, and C are incorrect as they do not directly relate to manipulating variables in an experiment.

2. Which field of psychology studies attitude change and group behavior?

• A. Developmental psychology
• B. Social psychology
• C. Psychoanalysis
• D. Psychometrics

Correct answer: B

Rationale: The correct answer is B: Social psychology. Social psychology specifically focuses on studying topics like attitude change and group behavior. Developmental psychology (Choice A) primarily deals with human growth and development across the lifespan. Psychoanalysis (Choice C) is a theoretical approach to psychology developed by Sigmund Freud focusing on the unconscious mind and childhood experiences. Psychometrics (Choice D) involves the measurement of psychological variables such as intelligence, personality traits, and abilities.

3. When examining heredity, mental disorders are almost always ________

• A. influenced by one particular gene.
• B. influenced by multiple genes.
• C. influenced by recessive genes.
• D. not influenced by genes.

Correct answer: B

Rationale: When examining heredity, mental disorders are influenced by multiple genes. Mental disorders are complex conditions that typically result from a combination of genetic, environmental, and other factors. While genetics play a significant role in predisposing individuals to mental disorders, it is rare for a single gene to be solely responsible for a mental disorder. Therefore, choice B is correct. Choices A, C, and D are incorrect because mental disorders are not usually influenced by one particular gene, recessive genes specifically, or not influenced by genes at all.

4. Children raised in orphanages tend to have ________.

• A. more cortical gray matter than those raised by their parents.
• B. less cortical gray matter than those raised by their parents.
• C. more friendships than those raised by their parents.
• D. fewer friendships than those raised by their parents.

Correct answer: B

Rationale: The correct answer is B: 'less cortical gray matter than those raised by their parents.' Studies have shown that children raised in orphanages tend to have less cortical gray matter compared to those raised by their parents. This is due to the lack of individualized care, attention, and stimulation that can negatively impact brain development. Choices A, C, and D are incorrect because there is no direct correlation between cortical gray matter and the number of friendships when comparing children raised in orphanages and those raised by their parents.

5. A baby throws its arms out and then inward (as if embracing) in response to loud noise or when its head falls. Which reflex is this?

• A. Babinski
• B. Palmar
• C. Darwinian
• D. Moro

Correct answer: D

Rationale: The correct answer is D, Moro. The Moro reflex is an instinctual response seen in infants when they experience a sudden loss of support or loud noise. The baby will throw their arms out and then bring them back in, resembling an embrace. This reflex is important for survival as it helps the infant react to potential dangers. Choice A, Babinski, refers to the reflex where a baby's toes spread apart when the sole of the foot is stimulated. Choice B, Palmar, is related to the reflex where a baby's fingers close tightly around an object placed in their palm. Choice C, Darwinian, is not a recognized reflex in this context.
