Final answer:
According to Freud, the ego is the rational component of our personality that balances the impulsive id and the moralistic superego, which makes the statement that ego strength contributes to logical reasoning and effective problem solving true.
Step-by-step explanation:
The statement that according to Freud, logical reasoning and effective problem solving come from ego strength is true. In Freud's structural model of the psyche, the ego functions as the rational part of our personality, which operates on the reality principle. Its main task is to mediate between the desires of the id, which demands immediate gratification, and the superego, which represents the moral standards and ideals acquired from society.
A person with a strong ego is capable of balancing these demands effectively, leading to behaviors that are both realistic and socially acceptable, hence facilitating logical reasoning and problem solving.
