To identify the scientist(s) most closely associated with the provided ideas, we can start by examining their contributions and theories. Here are the explanations for each idea:

1. The unfolding of abilities over the years:
This idea suggests that human abilities and behaviors develop and evolve over time. Three scientists are closely associated with this concept:

- Sigmund Freud: Freud proposed a psychodynamic theory of personality development, emphasizing the stages of psychosexual development from childhood to adulthood.
- Erik Erikson: Erikson is known for his theory of psychosocial development, which emphasizes the different stages individuals go through from infancy to late adulthood, focusing on social and emotional development.
- Jean Piaget: Piaget is best known for his theory of cognitive development, which explains how children's thinking and understanding progress through different stages during their development.

2. The process of acquiring behaviors from others:
This idea refers to learning behaviors by observing and imitating others. The scientist closely associated with this concept is Sigmund Freud. Freud's psychoanalytic theory emphasized the importance of the unconscious mind and how experiences during childhood shape an individual's personality and behavior.

3. Appropriate male-female behavior:
This idea pertains to social expectations and norms regarding the behavior of males and females. Sigmund Freud is the scientist closely associated with this concept. Freud's theories on psychosexual development explored how individuals develop their gender identities and the influence of unconscious desires and repression on gendered behaviors.

4. A child's way or plan for understanding the world:
This idea refers to how children develop their understanding and organize their knowledge about the world. The scientist most closely associated with this concept is Jean Piaget. Piaget's cognitive development theory proposed that children actively construct their understanding of the world through interactions and experiences, going through distinct stages of cognitive development.

Remember that there may be other scientists who have also contributed to these ideas, but these are the prominent ones associated with the concepts mentioned.
