Final answer:
Neurological support for Arnett's theory is exemplified by the concept of neuroplasticity, which shows the brain's capacity to adapt to change, including injury, stress, and pharmacotherapy, leading to altered behaviors and cognition.
Step-by-step explanation:
The neurological support for Arnett's theory can be understood through the study of neuroplasticity, which plays a crucial role in the brain's ability to adapt and recover from injury. Studies like those by Curtis et al. (2012) and Renton et al. (2014) suggest that recovery is supported by neurological adaptations such as synaptic changes, alterations in neurotransmitter systems, and the birth of new neurons. Neuroplasticity's effect on cognitive and affective functions indicates that with changes in the nervous system, individuals can experience shifts in cognition, affect, and behavior, aligning with Arnett's theory of developmental processes.
Research involving stress response, such as work by Aston-Jones and Cohen (2005), examines how the locus coeruleus-norepinephrine system, influenced by acute stressors, can adapt and thereby affect cognitive performance and behavior. Additionally, neuroanatomical changes associated with pharmacotherapy in conditions like PTSD, detailed by Bremner and Vermetten (2004), also contribute to the understanding of the nervous system's adaptability. Such adaptations are tangible proof supporting Arnett's theory, showing a correlation between neurological responses and behavioral outcomes.
