Final answer:
The statement is true. Karen Horney's theories explain that basic anxiety arises from childhood feelings of loneliness and helplessness, and she identified three coping strategies: affiliative dependence, aggression/assertiveness, and detachment/isolation.
Step-by-step explanation:
The statement that according to Horney, basic anxiety is the "all-pervading feeling of being lonely and helpless in a hostile world" is indeed true. Karen Horney's theories shed significant light on the role of unconscious anxiety in human development, particularly focusing on how children respond to this anxiety. Horney proposed that children cope with basic anxiety through three main coping strategies: moving toward people, which involves seeking affection and reliance on others; moving against people, characterized by aggression and assertiveness; and moving away from people, which centers on detachment and self-sufficiency.
Children who move toward people become dependent in an attempt to alleviate anxiety through obtaining love and acceptance. Those who move against people choose aggression as a means to combat feelings of insecurity. The ones who move away from people address their anxiety by isolating themselves and seek independence over interpersonal relationships.
