Exam 4 Psychology 101
1. While out for a walk, you come across a ferocious dog. You feel your heart beating faster and your palms begin to sweat. Which part of the peripheral nervous system is activated in this situation?
- A. Autonomic
- B. Sympathetic
- C. Parasympathetic
- D. Somatic
Correct answer: B
Rationale: The correct answer is B: Sympathetic. When encountering a stressful situation like a ferocious dog, the sympathetic nervous system is activated, leading to the 'fight or flight' response. This response triggers physiological changes like increased heart rate, sweating, and heightened alertness to prepare the body to deal with the perceived threat. The autonomic nervous system (Choice A) encompasses both the sympathetic and parasympathetic divisions, so it's a broader category. The parasympathetic nervous system (Choice C) is responsible for the body's 'rest and digest' functions, which are opposite to the physiological changes seen in a stress response. The somatic nervous system (Choice D) controls voluntary movements and sensory information, not the physiological responses seen in a stress reaction.
2. Which of the following psychodynamic elements of the personality can be described as impulsive and selfish?
- A. Ego
- B. Id
- C. Superego
- D. Ideal self
Correct answer: B
Rationale: The correct answer is B, Id. In psychodynamic theory, the Id is the component driven by basic, primal instincts, seeking instant gratification without consideration for consequences. It operates on the pleasure principle, aiming to fulfill desires immediately. The Superego, on the other hand, represents the internalized moral standards and ideals, while the Ego mediates between the Id and Superego, balancing impulses with societal norms. The 'Ideal self' is a concept from humanistic psychology related to one's aspirations and goals, not a component in psychodynamic theory. Therefore, choices A, C, and D are incorrect.
3. The genetic influences that determine behavior may never be fully understood due to ________
- A. the ease of researching to differentiate between the effects of the environment and the effects of genes.
- B. the likelihood that most behaviors are determined by the interaction of many genes and the environment.
- C. the tendency to rely on twin studies in genetic research.
- D. our significant understanding of how genes impact brain chemistry.
Correct answer: B
Rationale: The correct answer is B because most behaviors are influenced by a complex interaction of many genes and the environment. Choice A is incorrect because it states that it is easy to differentiate between the effects of the environment and genes, which is not the case. Choice C is incorrect because although twin studies are commonly used in genetic research, this alone does not hinder the full understanding of genetic influences on behavior. Choice D is incorrect because even though we have some understanding of how genes impact brain chemistry, this does not mean that we fully understand the genetic influences on behavior.
4. John Bowlby's attachment theory emphasized ________.
- A. the social environment in forming attachments.
- B. the quality of parental care in forming attachments.
- C. the quality of early reinforcers and stimulation in forming attachments.
- D. the necessity of independence from parental figures in forming attachments.
Correct answer: B
Rationale: John Bowlby's attachment theory emphasized the quality of parental care in forming attachments. This is because Bowlby believed that a child's early experiences with their primary caregiver, especially the quality of care and responsiveness received, significantly influence the child's ability to form secure attachments. Choice A is incorrect because while the social environment plays a role, Bowlby's theory focused more on the caregiver-child relationship. Choice C is incorrect as it does not capture the central role of parental care highlighted in Bowlby's theory. Choice D is also incorrect as Bowlby's theory actually emphasized the importance of a secure attachment to parental figures for healthy emotional development.
5. Cortisol is a hormone that ________.
- A. is released by the hypothalamus and travels to the pituitary gland, causing it to respond.
- B. the pituitary gland releases to stimulate the adrenal gland.
- C. the adrenal gland produces that mobilizes the body to deal with stress.
- D. reduces the reuptake of the monoamine neurotransmitters.
Correct answer: C
Rationale: Cortisol is a hormone produced by the adrenal gland that mobilizes the body to deal with stress. Therefore, choice C is the correct answer. Choices A and B are incorrect as they inaccurately describe the origin and function of cortisol. Choice D is also incorrect as it describes the action of a different type of substance, not cortisol.
