How does individual sentience vary with development (ontogeny) and age?
Context and Relevance:
Sentience, the ability to experience feelings and sensations, changes significantly throughout an organism's development and aging process. In early stages of development, sensory and neural systems are not fully formed, resulting in limited perceptual and affective experiences. As organisms mature, these systems become more sophisticated, enhancing their capacity to perceive and respond to environmental stimuli. In later life, the aging process may lead to a decline in sensory and cognitive functions, potentially reducing sentience.
Potential Research Approach:
Literature Review: Conduct a comprehensive review of scientific literature on the development and aging of sensory and neural systems in various animal species.
Developmental Studies: Use non-invasive imaging and behavioral tests to identify the stages at which sensory and neural mechanisms become fully functional in different species.
Behavioral and Welfare Analysis: Assess how the maturation of sensory and cognitive systems influences behavioral responses and welfare indicators in animals.
Aging Studies: Investigate the effects of aging on sensory and cognitive capacities and their impact on the welfare of different animal species using imaging and behavioral assessments.
Cross-Species Analysis: Compare developmental and aging data across species to identify common trends and unique patterns, and develop models explaining the evolution of sentience throughout an organism’s life.
Additional Questions:
1. At what developmental stages do sensory and neural mechanisms become fully functional in different species?
2. How does the maturation of sensory and cognitive systems influence behavioral responses and welfare in animals?
3. What are the effects of aging on the sensory and cognitive capacities of different animal species, and how do these changes impact their welfare?
