 MIND-MAP 1

Mind Map: Adult Development and Aging

1. Biological/Physical Domain

Subtopics:

 Theories of Aging
 Biological theories (metabolic, genetic programming, cellular)
 Free radical theory (damage from reactive molecules)

 Physical Changes
 Appearance: skin, hair, body build, voice
 Mobility: bone density, muscles, arthritis, osteoporosis
 Sensory systems: vision, hearing, taste, smell, touch
 Vital functions: cardiovascular, respiratory, immune systems
 Reproductive system: menopause, andropause

 Processes:
 Primary, secondary, tertiary aging
 Neuroplasticity: changes in neurons and neurotransmitters

 Connections:
 Physical decline can influence cognitive performance (slower processing speed)
 Physical activity improves cognitive function (exercise & neurogenesis)

 Research:
 International: Glasser et al., 2016 on brain connectivity
 South African: Local studies on aging population health trends (e.g., cardiovascular disease prevalence)
