Final answer:
Job satisfaction in middle adulthood does not universally increase; it is influenced by individual factors like personality, autonomy, and work content.
Step-by-step explanation:
The statement that job satisfaction increases throughout middle adulthood is generally considered to be false.
While some individuals may experience increased job satisfaction during this period due to factors like career advancement or achievement of personal goals, it is not a universal trend that can be applied to everyone in middle adulthood.
Job satisfaction is influenced by a variety of factors, including personality, autonomy, and work content, which vary widely among individuals.
