Final answer:
The statement is false. Carl Rogers discussed self-concept in terms of congruence between the real self and the ideal self.
Step-by-step explanation:
The statement that the three structural dimensions of self-concept are complexity, consistency, and clarity is false. Self-concept is a broad term that refers to how we see ourselves, and the way it is structured can vary according to different theories.
Psychologist Carl Rogers, a prominent humanistic theorist, discussed self-concept in terms of the real self and the ideal self, emphasizing the importance of congruence between the two for a healthy self-concept. Congruence is the state of being in which our thoughts about our real self and ideal self are very similar, which is crucial for a positive self-awareness.
Furthermore, trait theorists, such as those who developed the Five Factor Model, posit that personality is composed of five broad dimensions: openness, conscientiousness, extroversion, agreeableness, and neuroticism. While these factors are vital to understanding various components of personality, they are not directly referred to as 'structural dimensions of self-concept'. Therefore, the question as posed combines elements that are not traditionally bundled together in personality psychology or self-concept theory.
