This is an authoritarian father image. The accident at the beginning of the film has a profound influence on Marin's character building process. The blow of losing his wife and many children has caused Marin's demand for safety to expand infinitely, forming a character of insecurity, paranoia and lack of confidence. Any trouble at the bottom of the sea can make him feel like a frightened bird, and he extends this need to educate his children. Because Nemo is his only son, and Nemo has congenital defects, Marin's concern for his son leads him to control his son's behavior in almost everything. Marin has formed an avoidance conflict in the motivation of educating children. He not only wants his children to grow up independently and face the society, but also fears that they will be in danger in the process of independent action. When the two motives conflict, security needs prevail, which makes him put forward various restrictions on the individual behavior of children.
When Nemo was captured by human beings, finding his son became the driving force of all future behaviors of Marin. So when he mistakenly thought that his son was dead, Marin lost his goal and motivation and went back in despair. In the process of searching for his son, Marin's sense of self-efficacy gradually increased, which is also a good turning point in Marin's personality shaping. At the end of the film, Marin's behavior contrasts with the beginning. It is a comparative process of Ma Lin's psychological changes from being awakened by children to being awakened by children to going to school. In the process of overcoming difficulties, Marin's character has also been well developed.
Compared with his father, Nemo has the momentum that newborn calves are not afraid of tigers. Because of his natural defects, Nemo's respect needs to be the main factor of his motivation. He wants to be recognized and affirmed. His father's tyranny made him rebellious, and because of long-term wrong education, his self-efficacy was low. On the one hand, he did something contrary to his father's expectation to prove his ability, on the other hand, he lacked confidence in himself. His experience in the fish tank made him gradually determine his ability. When he heard that his father was looking for him in the whole sea, Nemo resolutely decided to run away regardless of the danger. At the end of the film, Nemo jumps into the fishing net and tries to escape from human capture with all the fish. This is a manifestation of his self-confidence, which also influenced his father and made his father's character develop in a positive direction.
Dolly is a special image in the film, a fish with amnesia. Amnesia makes Dolly sanguine and extroverted. Her high forgetfulness of pain and frustration makes her an optimistic and lively fish, but amnesia also forms a sense of loss in her subconscious. Dolly first helped Marin find Nemo, which is a reflection of her social personality motivation. Later, getting along with Marin made her find her memory improved. She remembered something related to Marin, which just made up for the lack of her subconscious, so it became Dolly's internal motivation to continue to look for Nemo with Marin.
The film puts forward the important influence of social environment on personality formation, and mutual assistance is an important factor for the benign development of personality. In the film, the shaping of characters' personalities is carried out in the interaction with others. Marin's distrust gradually changed his relationship with Dolly. With the help of others, he constantly overcame difficulties, increased his sense of self-efficacy, gradually established trust and confidence in others, and turned his melancholy character into an optimistic one. Nemo's need for respect is also met by getting along with other fish. The expectations and demands of other fish in the fish tank promoted Nemo's demands on himself, and overcoming difficulties also made him affirm his ability. Dolly's sense of loss caused by amnesia was filled by marin. Each character completes the shaping of self-personality with the help of others, which is also the world view reflected in the film. Concern, mutual assistance, trust and the desire for freedom are the driving forces of human development.
