Final answer:
The actualizing tendency emphasizes the client's innate drive towards personal growth, while the organismic valuing system focuses on the client's evaluations of experiences.
Step-by-step explanation:
The key distinction between the client-centered concepts of the actualizing tendency and the organismic valuing system is that:
a) The actualizing tendency emphasizes the client's innate drive towards personal growth, while the organismic valuing system focuses on the client's evaluations of experiences.
The actualizing tendency, as proposed by Carl Rogers, refers to the natural tendency of individuals to strive towards personal growth and self-actualization. It is the client's innate, internal drive to reach their full potential. On the other hand, the organismic valuing system involves the client's evaluations and judgments of their experiences, including their own feelings and values. It is the client's self-directed process of determining what is important and meaningful to them.
Overall, while both concepts are related to personal growth and self-awareness, the actualizing tendency emphasizes the client's drive towards growth, while the organismic valuing system focuses on the client's evaluations of their experiences.
