Psychology 2301 Exam 1

Correct Answer: B

Rationale: The correct term for conditions that increase the probability of a disorder but are neither necessary nor sufficient to cause it is 'Contributory causes.' Risk factors (Choice A) are conditions that increase the likelihood of a negative outcome but do not imply causation. Sufficient causes (Choice C) are conditions that guarantee the occurrence of a disorder by themselves. Protective factors (Choice D) decrease the likelihood of a disorder rather than increasing it.

Correct Answer: B

Rationale: The correct answer is B because most behaviors are influenced by the interaction of multiple genes and the environment. Choice A is incorrect because it suggests that researching the effects of the environment and genes is easy, which is not the case. Choice C is incorrect as it focuses on a specific method (twin studies) rather than the broader concept of gene-environment interaction. Choice D is incorrect as the statement implies a high level of understanding that contradicts the idea that genetic influences on behavior may never be fully understood.

Correct Answer: B

Rationale: Extinction is the process of eliminating a conditioned response by repeatedly presenting the conditioned stimulus without the unconditioned stimulus. This process helps in reducing or eliminating undesired behaviors or responses. Choice A is incorrect because extinction weakens the conditioned response by breaking the association between the conditioned stimulus and the unconditioned stimulus. Choice C is incorrect as extinction is a widely used technique in behavioral therapies for treating disorders. Choice D is incorrect as extinction aims to reduce the conditioned response, not intensify it.

Correct Answer: B

Rationale: The correct answer is B: Synapse. The synapse is the site where chemical communication occurs between neurons. Neurotransmitters are released from the axon terminal of one neuron, cross the synaptic cleft, and bind to receptors on the dendrites of the next neuron. Choice A, Neuron, is incorrect as it refers to the entire nerve cell. Choices C and D, Axon and Dendrite, are also incorrect as they are specific parts of a neuron and not the primary site of chemical communication.

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.
