Psychology 101 Final Exam

1. Why is it particularly useful to study identical twins who were raised in different environments?

A. Differences in brain function can be easily identified.
B. Concordance rates tend to be higher.
C. It is possible that the genetics of twins who have been separated have changed in ways to explain any differences found.
D. It is possible that high concordance rates between identical twins reared together are due to their being treated more similarly than nonidentical twins.

Correct answer: D

Rationale: Studying identical twins raised in different environments allows researchers to understand the impact of genetics versus environmental factors on traits. Choice A is incorrect because differences in brain function can be influenced by a variety of factors and not solely by environmental differences. Choice B is incorrect as concordance rates tend to be higher in identical twins reared together due to shared genetics and environment. Choice C is incorrect because genetics do not change due to being raised in different environments.

2. Latresha is not hungry, is extremely tired, and doesn't feel like doing much of anything. She often feels that life is just hopeless. These symptoms have been going on for 2 months now. She probably is suffering from which mood disorder?

A. Generalized anxiety disorder
B. Bipolar disorder
C. Major depressive disorder
D. Obsessive-compulsive disorder

Correct answer: C

Rationale: The correct answer is C, Major Depressive Disorder. Latresha's symptoms of prolonged sadness, fatigue, and lack of interest in activities lasting for 2 months indicate a major depressive episode. Generalized anxiety disorder (A) is characterized by excessive worry and anxiety, not necessarily prolonged sadness. Bipolar disorder (B) involves episodes of both mania and depression, not solely prolonged sadness. Obsessive-compulsive disorder (D) is characterized by obsessions and compulsions, not the symptoms described in the scenario.

3. Which of the following is an example of telegraphic speech?

A. A child pointed to his father's shoe and said 'daddy,' as if to convey 'daddy's shoe.'
B. A thirsty toddler said, 'mama water.'
C. A newborn infant asked, 'Can I have some coffee?'
D. A baby communicated to her parents using her brain.

Correct answer: B

Rationale: The correct answer is B. Telegraphic speech is when a child uses a two-word phrase to convey a larger meaning, such as 'mama water.' Choice A is incorrect as it does not demonstrate telegraphic speech but rather a simple labeling. Choice C is incorrect as it is a complete sentence and not a two-word phrase. Choice D is also incorrect as it does not describe telegraphic speech but rather a vague statement about communication.

4. What are psychology's intellectual parents?

A. Physics and physiology.
B. Philosophy and physiology.
C. Chemistry and physics.
D. Philosophy and chemistry.

Correct answer: B

Rationale: Psychology's intellectual parents are philosophy and physiology. Philosophy contributed to the early development of psychology by exploring questions about the mind and behavior, while physiology provided a scientific foundation for understanding the biological aspects of human psychology. Choices A, C, and D are incorrect as they do not accurately represent the disciplines that significantly influenced the emergence of psychology as a distinct field of study.

5. Which parental style is characterized by warmth, control, and communication?

A. Authoritarian
B. Permissive/indulgent
C. Authoritative
D. Neglectful/uninvolved

Correct answer: C

Rationale: The correct answer is C, Authoritative. The authoritative parenting style is characterized by a balance of warmth, control, and communication. This style promotes a nurturing environment where parents set clear rules and boundaries while also being responsive to their child's needs. Choice A, Authoritarian, is characterized by strict rules and high control with less warmth and communication. Choice B, Permissive/indulgent, involves high warmth but low control, where rules are not clearly established. Choice D, Neglectful/uninvolved, lacks both warmth and control, with little to no communication or involvement in the child's life.
