Question

one area of challenge for learning by observation theorists is _________. single-track on anti-social emphasis on observing others single-track on pro-social a focus on child development

Explanation:

Learning by observation (social learning theory) has challenges. The option "single - track on anti - social" is incorrect as it's not a main challenge. "Emphasis on observing others" is part of the theory, not a challenge. "A focus on child development" is not a challenge. The challenge is being "single - track on pro - social" as the theory's research or application may overly focus on pro - social learning and not adequately address other aspects or types of learning, or not account for a broader range of behaviors beyond pro - social ones.

Answer:

single - track on pro - social
