Questions: Paul Baltes' theory emphasizes that development is a lifelong process.

The answer is lifelong.

Paul Baltes' theory of development, known as the life-span perspective, emphasizes that development is a lifelong process. This perspective suggests that development does not stop at a certain age but continues throughout an individual's life, encompassing changes and growth in various domains such as cognitive, emotional, and social aspects.

A linear process implies a straightforward, unidirectional progression, which does not align with Baltes' view. Baltes argued that development is multidirectional, meaning that it can involve both gains and losses at different stages of life.

Short-term development would suggest changes that occur over a brief period, which contradicts Baltes' emphasis on the continuous nature of development throughout the entire lifespan.

A static process would imply no change or development, which is contrary to Baltes' theory. He believed that development is dynamic and ongoing, involving adaptation and change over time.
