A 28-year-old accountant is admitted to the neurologic unit after a sudden onset of blindness the day before an important project is due for her boss. After preliminary evaluation and testing yields no positive findings, the physician’s initial reaction is that the client may be demonstrating which defense mechanism ？（）
A．Repression.
B．Transference.
C．Reaction formation.
D．Conversion.
参考答案：D
解析：
A person can convert unbearable feelings into a physical symptom with no organic cause. This defense mechanism usually manifests itself near the time of a traumatic or conflict-producing event. The symptom commonly provides attention or a means of escaping the conflict. Repression is a defense mechanism in which a person unconsciously keeps unwanted feelings from entering awareness. Transference involves the projection of feelings, thoughts, and wishes (positive or negative) onto someone, usually a therapist, who represents a figure from the person’s past. Reaction formation is a means of alleviating unresolved conflicts between feelings or impulses by reinforcing one feeling and repressing another, thereby disguising the true feelings from the self.
