( x ) Age-related declines in processing speed and cognitive flexibility are associated with 
reduced synaptic plasticity and neurogenesis, reflecting broader patterns of 
neurodegeneration and cognitive decline in aging populations. 
( ) Cognitive flexibility improves with age. 
( ) Aging does not affect cognitive processes. 
 
58. How do the neurobiological underpinnings of reward processing inform our 
understanding of compulsive behaviors, particularly in the context of gambling addiction 
and its effects on decision-making? 
( ) Compulsive behaviors are purely psychological. 
( ) Reward processing is not related to decision-making. 
( x ) Dysregulation in the brain's reward circuitry, particularly involving the nucleus 
accumbens and prefrontal cortex, contributes to compulsive behaviors like gambling 
addiction, impairing decision-making and reinforcing risky choices. 
( ) Decision-making is unaffected by addiction. 
( ) Reward processing is exclusive to positive outcomes. 
 
59. In the context of the social brain hypothesis, what neuroanatomical structures are 
implicated in social cognition, and how does this relate to the evolution of human 
intelligence? 
( ) Social cognition is unrelated to brain structure. 
( ) The social brain hypothesis is outdated and irrelevant. 
( x ) Neuroanatomical structures such as the medial prefrontal cortex and temporoparietal 
junction are crucial for social cognition, supporting the idea that the demands of social 
living have driven the evolution of human intelligence and brain complexity. 
( ) Intelligence is solely a product of environmental factors. 
( ) Social cognition is fixed and does not evolve over time. 
 
60. How does the understanding of the neural correlates of creativity contribute to our 
comprehension of the cognitive processes involved in creative thinking, and what brain 
regions are primarily engaged during creative tasks? 
( ) Creativity is unrelated to brain function. 
( ) Creative thinking is solely localized to the left hemisphere. 
( x ) Research indicates that creative thinking engages multiple brain regions, including the 
default mode network and the executive control network, highlighting the interplay 
between divergent and convergent thinking processes. 
( ) Creativity is a fixed trait with no neural basis. 
( ) The brain's structure does not influence creative ability. 
 
61. In exploring the effects of chronic sleep deprivation on cognitive function, what 
neurobiological mechanisms are implicated in the decline of attention and memory 
consolidation, and how do these effects reflect broader patterns of brain health? 
( ) Sleep deprivation has no impact on cognitive function. 
( ) Attention and memory are solely affected by environmental factors. 
( x ) Chronic sleep deprivation disrupts neurotransmitter systems and impairs synaptic 
plasticity, leading to declines in attention and memory consolidation, which reflect 
broader detrimental effects on overall brain health. 
( ) Cognitive functions improve with sleep deprivation. 
( ) The effects of sleep deprivation are reversible and do not persist. 
 
62. How do the neural networks involved in moral decision-making illustrate the 
complexities of human ethics, particularly in the context of empathy, reasoning, and 
emotional regulation? 
( ) Moral decision-making is unrelated to neural processes. 
( ) Ethics are solely a product of cultural influences. 
( x ) Neural networks involving the prefrontal cortex, amygdala, and insula interact during 
moral decision-making, illustrating the complexities of how empathy, reasoning, and 
emotional regulation influence ethical judgments. 
( ) Empathy has no role in ethical decision-making. 
( ) Moral reasoning is fixed and does not involve emotional processes. 
 
63. In the study of the neural basis of visual perception, how do top-down and bottom-up 
processing interact to shape our understanding of visual stimuli, and what implications 
does this have for perceptual disorders? 
( ) Visual perception is solely a bottom-up process. 
( ) Top-down processing has no impact on perception. 
( x ) Top-down processing involves the influence of prior knowledge and expectations on 
perception, while bottom-up processing is driven by sensory input; their interaction is 
crucial for understanding visual stimuli and can help explain perceptual disorders. 
( ) Perceptual disorders are unrelated to visual processing. 
( ) Visual stimuli are processed in isolation without integration. 
 
64. How does the concept of neurodiversity enhance our understanding of cognitive 
differences in conditions such as autism and ADHD, and what implications does this have 
for education and social inclusion? 
( ) Neurodiversity has no relevance in understanding cognitive differences. 
( ) Cognitive differences are solely deficits that need to be corrected. 
( x ) Neurodiversity emphasizes the value of cognitive differences as part of human 
diversity, promoting acceptance and tailored educational approaches that recognize 
individual strengths and needs in autism and ADHD. 
( ) Education should be uniform for all cognitive profiles. 
( ) Social inclusion is unrelated to cognitive diversity. 
 
65. In investigating the relationship between physical health and mental well-being, how 
do neurobiological pathways link chronic illness to mental health outcomes, particularly 
in the context of inflammation and neurotransmitter systems? 
( ) Chronic illness has no impact on mental health. 
( ) Neurobiological pathways do not connect physical and mental health. 
( x ) Chronic illness can lead to increased inflammation and dysregulation of 
neurotransmitter systems, negatively affecting mental health outcomes and highlighting 
the interconnectedness of physical and mental well-being. 
( ) Mental health is only influenced by psychological factors. 
( ) The brain does not respond to physical health changes. 
 
66. How do the findings from studies on the effects of mindfulness and meditation on 
brain function inform our understanding of emotional regulation and cognitive flexibility? 
( ) Mindfulness has no effect on cognitive function. 
( ) Meditation only benefits physical health. 
( x ) Research shows that mindfulness and meditation can lead to structural and 
functional changes in the brain, enhancing emotional regulation and cognitive flexibility 
through mechanisms such as increased gray matter density in regions associated with 
self-regulation. 
( ) Cognitive flexibility is fixed and cannot be improved. 
( ) The effects of mindfulness are purely temporary.
