Undergraduate and graduate counseling students listened to two audio recordings and wrote explanations. Their explanations were rated as either simple or complex. All undergraduate explanations were rated as simple, simply describing what was said. All graduate student explanations were rated as complex, providing critical assessment. However, three graduate students made an error in clinical thinking by claiming religious belief in God speaking indicated schizophrenia. The study shows graduate students demonstrated more complex thinking, but educators need to address clinical reasoning errors.
