Final answer:
Carl Rogers would call the acceptance and love Savannah's parents have for her no matter what she does 'unconditional positive regard.' This reflects a key aspect of Rogerian theory, emphasizing total acceptance to foster positive self-growth.
Step-by-step explanation:
The concept that Carl Rogers would use to describe Savannah's understanding that her parents will always love and accept her, regardless of the trouble she gets into at school, is unconditional positive regard. This term refers to an attitude of total acceptance and support of a person no matter what they say or do. Rogers believed that by receiving unconditional positive regard, individuals develop a healthier self-concept and are more likely to grow in positive directions.
In contrast to option (a), the Oedipus complex mentioned in option (b) refers to a concept identified by Sigmund Freud and involves a child's feelings of desire for the opposite-sex parent and jealousy towards the same-sex parent during the phallic stage of psychosexual development. An ego defense mechanism as in option (c) is a strategy the ego uses to protect itself from anxiety by distorting reality. Option (d), superego development, involves the part of the psyche that holds internalized moral standards and ideals that we acquire from our parents and society.
Therefore, the correct answer is (a) Unconditional positive regard.
