What neurotransmitter was first believed to be the cause of schizophrenia?

Correct Answer: D

Rationale: The correct answer is Dopamine. Dopamine was initially thought to be the primary cause of schizophrenia. This neurotransmitter hypothesis was based on the observation that drugs that increase dopamine activity can worsen symptoms of schizophrenia, while drugs that decrease dopamine activity can improve symptoms. Choices A, B, and C are incorrect because GABA, serotonin, and epinephrine were not the neurotransmitters initially believed to be the cause of schizophrenia.

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.

Correct Answer: A

Rationale: The correct answer is 'Theory of mind.' Theory of mind is the understanding that others have their own thoughts, feelings, and intentions. This ability allows individuals to attribute mental states to others, enabling them to understand and predict behavior based on those mental states. Choices B, C, and D are incorrect because they do not specifically address the awareness of others' intentions, desires, wants, and motives.

Correct Answer: C

Rationale: The correct answer is C: 'Ambivalent.' Children with an ambivalent temperament are indeed generally mild but hesitant about accepting new experiences. This temperament is characterized by a combination of mildness and hesitance. Choice A, 'Secure,' refers to children who are comfortable with both their caregiver's presence and absence, showing a secure attachment style. Choice B, 'Avoidant,' describes children who tend to avoid or ignore their caregiver, displaying an insecure attachment style. Choice D, 'Disorganized,' represents children with inconsistent or confused behaviors towards their caregiver, exhibiting an insecure and disoriented attachment style.

Correct Answer: D

Rationale: The correct answer is D, Sigmund Freud. Freud's psychoanalytic theory emphasized the influence of unconscious motivations on behavior. This aligns with the faculty member's statement about people being unaware of the unconscious drives behind their actions. Choice A, F. Skinner, is incorrect because Skinner focused on observable behavior and reinforcement. Choice B, Carl Rogers, is incorrect as Rogers is associated with humanistic psychology and self-actualization, not unconscious motivations. Choice C, Wilhelm Wundt, is also incorrect as he is known for establishing the first psychology laboratory and structuralism, not unconscious motivations.

Correct Answer: C

Rationale: Gabriel's reaction of turning down the offer of job interview books from his friend despite being depressed and unsuccessful in job hunting best fits the concept of learned helplessness. Learned helplessness occurs when individuals believe they have no control over their situation, leading to passivity and feelings of helplessness. In this case, Gabriel's refusal of the books indicates a sense of resignation and belief that his efforts in finding a job will not be successful, reflecting learned helplessness. Observational learning, insight learning, and modeling do not directly align with Gabriel's reaction in this context.

Correct Answer: C

Rationale: Bernard's advice to focus on observable behaviors aligns with the behavioral perspective. Behaviorists emphasize studying external actions rather than internal states to understand human behavior. The psychodynamic perspective (Choice A) focuses on unconscious processes, the evolutionary perspective (Choice B) on adaptation and natural selection, and the biological perspective (Choice D) on the biological underpinnings of behavior, making them less similar to Bernard's suggestion.

Correct Answer: C

Rationale: The correct answer is C: Reactive attachment disorder. Individuals with reactive attachment disorder have a history of severe social neglect, which distinguishes it from autism spectrum disorder. Choice A, Schizoid personality disorder, is incorrect as it is not typically associated with the history described in reactive attachment disorder. Choice B, Autism spectrum disorder, is incorrect because individuals with autism spectrum disorder do not necessarily have a history of severe social neglect. Choice D, Disinhibited social engagement disorder, is also incorrect as it is a separate attachment disorder characterized by indiscriminate social behavior, not necessarily a history of neglect.

Correct Answer: B

Rationale: The correct answer is B: Proximodistal pattern. Differences between monozygotic twins raised in the same environment are likely due to non-shared environmental influences, which lead to differences in interests, hobbies, and other individual characteristics. Choices A, C, and D are incorrect. Cephalocaudal pattern refers to the principle of development from head to toe, not relevant in explaining differences between twins. Cephamodistal pattern is not a recognized developmental term. Gene-environment correlation does not directly explain the differences between identical twins raised in the same environment.
