Exam 4 Psychology 101

Correct Answer: B

Rationale: The correct answer is B, Monozygotic twin. A monozygotic twin, also known as an identical twin, is the result when a single zygote splits into two parts, leading to the development of two genetically identical individuals. Choices A, C, and D are incorrect because they do not accurately describe the scenario where a single zygote splits into two parts to form identical twins. Dizygotic twin (Choice A) refers to fraternal twins, which result from two separate eggs fertilized by two different sperm cells. Fraternal twin (Choice C) is another term for dizygotic twins, arising from two separate zygotes. Nonidentical twin (Choice D) is a synonymous term for dizygotic or fraternal twins, indicating that they are not genetically identical.

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.

Correct Answer: D

Rationale: John Watson was a key figure in the development of behaviorism, which advocated for focusing on observable behavior rather than the study of consciousness. Choice D is the correct answer because Watson believed that psychology should abandon the study of consciousness. Choices A, B, and C are incorrect because Watson's approach emphasized behavior and rejected the importance of consciousness, introspection, or confining psychology to only mentally ill individuals.

Correct Answer: C

Rationale: The correct diagnosis for Roger's condition is Broca's aphasia. Broca's aphasia is characterized by difficulty in speaking fluently and accurately, often due to brain injury. In this case, Roger's symptoms of being unable to speak fluently, mispronouncing words, and speaking haltingly align with the characteristics of Broca's aphasia. Agnosia refers to the inability to recognize or interpret sensory information, spatial neglect is the lack of awareness of one side of the body or space, and prosopagnosia is the inability to recognize faces, none of which match Roger's symptoms.

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.
