Final answer:
Our notions about a client can interfere with effective listening if they are based on biases or stereotypes.
Step-by-step explanation:
In effective listening, our notions about a client can interfere with the process. These notions may include biases or preconceived ideas we have about the client based on their race, gender, or background. Such notions can lead to unintentional stereotyping, where we make assumptions about the client without taking into account their individuality. For example, if we have negative stereotypes about a certain group, we may be less receptive to their communication and not truly listen to what they are saying.
