Final answer:
Adlerians do not believe that childhood experiences are solely decisive in shaping personality; rather, Adler's theory suggests a more dynamic interplay of factors, including social influences and individual striving for superiority.
Step-by-step explanation:
The statement that Adlerians believe childhood experiences in themselves are the decisive factor in shaping personality is False. Alfred Adler, a prominent figure in psychology, emphasized the importance of social context and an individual's proactive role in shaping their personality. While Adler acknowledged that childhood experiences influence personality development, he did not view them as determinative. Instead, Adler proposed that our personality is significantly shaped by our efforts to overcome feelings of inferiority and strive for superiority, a concept known as the inferiority complex. He also introduced the idea of the influence of birth order on personality, suggesting that our position among siblings can affect our personality traits. However, our personalities are more dynamically influenced by a range of factors, including genetic, social, and environmental variables throughout our lives.
